SAN DIEGO, USA—A frequently fatal side effect of immune checkpoint inhibition known as the “Triple M Overlap Syndrome” can be predicted if myocarditis is noted in the first month of immunotherapy. That’s according to researchers who reported study findings at the 2026 Annual Meeting of the American Association for Cancer Research.

First author Hassan Abushukair MD, a Post-Doctoral Researcher at Oklahoma University Stephenson Cancer Center in Oklahoma City gave the details to Peter Goodwin.

STUDY CONCLUSION:

“This is the largest global dataset to characterize TMOS and MC fatality. Our data shows that TMOS represents a uniquely fatal phenotype of ICI-MC with a higher tendency in cancers with wider ICI use. Regarding MC fatality, we show MC timing to be a critical determinant of fatality, specifically within the first month of ICI start, demonstrating the need for refined screening and monitoring strategies within this time window”

Background:

Immune checkpoint inhibitor (ICI)-induced myocarditis (MC) is one of the most fatal immune-related adverse events (irAEs) in cancer patients, often overlapping with myositis (MS) and myasthenia gravis (MG), forming the fulminant triad of Triple M Overlap Syndrome (TMOS). In this study, we report the largest clinical series of this rare fatal syndrome, aimed at delineating clinical features, fatality predictors, and temporal trends.

Methods:

We surveyed the WHO Vigibase pharmacovigilance database for cases of ICI- MC, MS, and MG in cancer cases through January 1, 2025. Seven groups emerged: MC alone, MS alone, MG alone, MC+MS, MC+MG, MS+MG, and TMOS. A machine learning (ML) model using the XGBoost algorithm was constructed using a subset (n = 858) of ICI- MC with complete data availability (age, sex, co-reactions, cancer/ICI type, and MC timing) for MC fatality prediction with an 80/20% data split for training and internal testing. An external public real-world dataset (n = 28) of ICI-MC was used for independent validation of our fatality ML prediction model.

Results:

Among a total of 4,950 ICI-MC/MS/MG cases, we identified 2,641 ICI-MC cases, of which 1,911 (72.4%) were MC alone and 730 (27.6%) were overlapping with MS and/or MG (MC+MS = 364, 13.8%; MC+MG = 159, 6%; TMOS = 207, 7.8%). TMOS occurred predominantly in melanoma (35.8%) and was more likely in males (64.7% vs 52.9%, p- value = 0.0049) treated with ICI dual therapy (25.1% vs 20.4%, p-value = 0.0030) compared with MC alone. Hepatitis was the most common irAE co-occurring in cases with TMOS (n = 30, 14.5%). MC-specific fatality rates were higher in TMOS (38%) compared to MC alone (21.2%), MC+MS (22.5%), or MC+MG (25.7%). MC alone had a later onset from ICI start than MC+MS, MC+MG, and TMOS (median time-to-MC: 60.8, 27, 27, and 26 days, respectively; p < 0.05). Early-onset MC within the first month of ICI initiation was independently associated with increased MC fatality after adjustment for age, ICI regimens, cancer type, and co-reactions (≤1 vs 1-3 months – OR: 0.41, 95% CI [0.22- 0.73], p-value = 0.0036; ≤1 vs 3-12 months – OR: 0.44, 95% CI [0.21-0.86], p-value = 0.0212). Our final MC fatality classifier achieved an AUC of 0.79, 0.75, and 0.85 with the training (n = 686), internal testing (n = 172), and external independent validation (n = 28) datasets, respectively, with the top predictive features for MC fatality being early-onset MC occurrence (within the first month of ICI start) and cardiorespiratory co-reactions.

Conclusion:

This is the largest global dataset to characterize TMOS and MC fatality. Our data shows that TMOS represents a uniquely fatal phenotype of ICI-MC with a higher tendency in cancers with wider ICI use. Regarding MC fatality, we show MC timing to be a critical determinant of fatality, specifically within the first month of ICI start, demonstrating the need for refined screening and monitoring strategies within this time window.

PRESS RELEASE:

Early Myocarditis Onset After Immunotherapy May Predict Treatment- related Fatality

Co-occurrence of myocarditis with myositis and myasthenia gravis may also increase risk of death

SAN DIEGO – Patients who developed myocarditis within the first month of receiving immune checkpoint inhibitor therapy were more likely to die of myocarditis, and myocarditis-specific fatality was more common in patients who experienced co-occurring myositis and myasthenia gravis, according to results from a study presented at the American Association for Cancer Research (AACR) Annual Meeting 2026, held April 17-22.

Immune checkpoint inhibitors (ICIs) have ushered in a new era of cancer immunotherapies, but on rare occasions, they can cause myocarditis, which can prove more immediately deadly than the cancers the drugs are meant to treat in some cases, explained Hassan M. Abushukair, MD, a postdoctoral researcher at the Oklahoma University Stephenson Cancer Center, who presented the study.

When ICIs cause myocarditis, he added, they can often also cause myositis (autoimmune muscle inflammation) and myasthenia gravis (nerve-muscle communication disruption), which come together to form what researchers term “triple-M overlap syndrome,” or TMOS.

“TMOS and the conditions that compose it can easily cause fatalities for the subset of ICI-treated patients who develop these side effects. But clinicians need to know who may be at the greatest risk for fatal outcomes, and we do not yet have that level of understanding,” said Abushukair. “Our analysis aimed to identify how we can more systematically approach risk stratification for patients who may develop fatal cardiac and autoimmune side effects from ICI treatment.”

Abushukair and colleagues identified ICI-induced myocarditis, myositis, and myasthenia gravis in cancer cases within the World Health Organization (WHO) VigiBase pharmacovigilance databases. From this dataset, they formed seven groups of ICI side effects of concern: myocarditis alone; myositis alone; myasthenia gravis alone; myocarditis and myositis; myocarditis and myasthenia gravis; myositis and myasthenia gravis; and TMOS.

Out of 4,950 cases of myocarditis, myositis, and myasthenia gravis identified within the dataset, the researchers identified 2,641 ICI-induced myocarditis cases. Of those instances of myocarditis, 1,911 (72%) were myocarditis alone, and 730 (27.6%) overlapped with myocarditis and/or myasthenia gravis. The most common overlap combination was myocarditis and myositis (364 cases), followed by TMOS (207 cases). An overlap of myocarditis and myasthenia gravis was the least common combination, with 159 cases.

Following the start of ICI therapy, myocarditis had a significantly later median date of onset (60.8 days) than myocarditis and myositis (27 days); myocarditis and myasthenia gravis (27 days); and TMOS (26 days).

After adjusting for age, ICI regimens, cancer type, and co-reactions, the researchers found that myocarditis occurring during the first month of ICI therapy start was associated with a significantly increased likelihood of myocarditis-specific fatality. Patients with ICI-induced myocarditis that began less than a month after starting treatment were 59% more likely to die from myocarditis than those whose myocarditis began one to three months after starting treatment; they were also 56% more likely to die from myocarditis than those whose ICI-induced myocarditis occurred three to 12 months after starting treatment.

Myocarditis-specific fatality was highest in patients with TMOS (38%). Deaths attributable to myocarditis were less frequent in patients with myocarditis alone (21.2%); myocarditis and myositis (22.5%); and myocarditis and myasthenia gravis (25.7%).

The team is also developing an algorithm to predict fatality from ICI-induced myocarditis by using machine learning based on 858 cases of ICI-induced myocarditis with complete data availability. The researchers’ tool achieved considerable accuracy in classifying fatal and nonfatal cases.

“Our analysis indicates that the first month of a patient receiving ICI therapy is the crucial period for determining patients’ risk of myocarditis fatality. If a patent on ICIs develops myocarditis in those first 30 days, that’s a flashing warning light,” said Abushukair. “This gives clinicians an actionable timeframe for determining whom ICI therapy may be dangerous for.”

Abushukair also spoke to the potential of his team’s algorithmic model, which he hopes, following additional training data and validation currently ongoing, might have use on the clinical side for patient monitoring and risk stratification for patients receiving ICI therapy.

“I believe the model we’re developing is a great illustration of how even simple clinical data analysis can be used to address fatality in cancer treatment. Ultimately, we envision a helpful bedside tool to rule out high-risk fatality from TMOS and its constituent conditions,” he said. “With a greater understanding of the risks that these ICI side effects pose, clinicians and patients alike can be more attuned to which symptoms to be on the lookout for. Our hope is that this will create a safer paradigm for ICI treatment.”

Limitations of this study include its retrospective, descriptive design and the use of a global dataset that contained considerable heterogeneity for various protocols, thresholds, etc. The WHO dataset also lacked complete treatment information.

Abushukair reports no funding sources for the study and discloses no conflicts of interest.

ASCO 2026 Abstract LBA5

Daraxonrasib, a RAS(ON) multi-selective inhibitor vs chemotherapy in previously treated metastatic pancreatic adenocarcinoma (mPDAC): Primary and final analysis from the phase 3 RASolute 302 study.

ASCO Presenting author:

Brian M Wolpin MD MPH, Dana-Farber Cancer Institute, Gastrointestinal Cancer Center, Boston, USA

Background:

Available 2L therapies offer limited clinical benefit in mPDAC with reported mPFS of 3–4 mo and mOS of 6–7 mo. Aberrant RAS pathway activation is the key driver of PDAC, with oncogenic RAS mutations (mut) identified in >90% of cases, most commonly at codon G12. Daraxonrasib is an oral, RAS(ON) multi-selective, tri-complex inhibitor of the active, GTP-bound state of mutant and wild type RAS.

Methods:

RASolute 302 (NCT06625320) is a global, randomized, open-label, Ph 3 study in pts with 2L mPDAC and ECOG PS 0-1. Pts were randomized 1:1 to receive daraxonrasib 300 mg PO QD or investigator’s choice of SOC cytotoxic chemo. Dual primary endpoints were OS and PFS by BICR in the RAS G12 mutant (RAS G12) population. Key secondary endpoints included OS and PFS by BICR in the overall population, ORR by BICR in RAS G12 and overall populations.

Results:

248 pts were randomized to daraxonrasib and 252 to chemo. Baseline characteristics were balanced between arms. At data cutoff (Feb 10, 2026; mFU: 8.5 mo), all primary and key secondary endpoints were met. Statistically significant, clinically meaningful improvements in OS and PFS were observed with daraxonrasib vs chemo in the RAS G12 and overall populations (Table). Gr ≥3 TRAEs occurred in 43.6% of pts receiving daraxonrasib vs 57.5% receiving chemo. The most common (≥10%) Gr ≥3 TRAEs were rash (13.7%) and stomatitis (12.0%) for daraxonrasib; neutrophil decrease (18.2%) and anemia (16.4%) for chemo. TRSAEs occurred in 10.8% of pts receiving daraxonrasib vs 18.7% receiving chemo. Discontinuation due to TRAEs occurred in 1.2% of pts for daraxonrasib vs 11.2% for chemo. Median/mean daraxonrasib dose intensity was 93.1%/84.7%.

Conclusions:

Daraxonrasib demonstrated unprecedented improvements in OS and PFS vs chemo in pts with 2L mPDAC with or without an identified tumor RAS mut. Daraxonrasib was generally well tolerated, with a manageable safety profile and with no new safety signals. Results support daraxonrasib as the new SOC for 2L mPDAC.

Background:

Ciltacabtagene autoleucel (cilta-cel), a B-cell maturation antigen (BCMA)- directed chimeric antigen receptor (CAR) T-cell therapy, is approved for patients with relapsed/refractory multiple myeloma after 1 line of therapy. In the CAR-PRISM trial, we hypothesized that early use of cilta-cel in patients with high-risk smoldering myeloma (HR-SMM) would yield even higher efficacy with the potential for cure. Here, we report the initial safety and efficacy results from the complete study cohort.

Methods:

In this single-center, phase 2 study, patients received a single infusion of cilta- cel at target doses of 0.3, 0.5, or >0.5×106 CAR+ T cells/kg following lymphodepleting chemotherapy. No induction or bridging therapy was administered. High-risk SMM was defined by the 20/2/20 model or bone marrow plasma cells >10% with additional adverse features. Patients with >40% infiltration were excluded. Primary endpoint was the incidence of dose-limiting toxicities (DLTs) and treatment-emergent adverse events (AEs); key secondary endpoints included overall response rate and minimal residual disease (MRD) negativity.

Results:

As of December 31, 2025, 20 patients (median age, 58 years; 6 women) received cilta-cel. No pre-specified DLTs were observed during the dose-escalation phase. The most common AEs were transient hematologic toxicities (neutropenia grade 4: 11/20, grade 3: 7/20; median duration 3 days). Cytokine release syndrome occurred in all patients (grade 1: 17/20, grade 2: 3/20). Non-ICANS neurologic toxicities (NINTs) occurred in seven patients, predominantly at the >0.5×106 dose level; five events were low grade and included facial palsy, tremor or paresthesia. Among two patients with movement and neurocognitive treatment-emergent AEs (MNTs); one patient’s work-up demonstrated CAR-T persistence and testing suggestive of a pre-existing synucleinopathy characterized by phosphorylated α-synuclein on skin biopsy and abnormal dopamine transporter imaging, whereas the other experienced grade 1 symptoms. Patients with NINTs showed significantly different longitudinal profiles, with higher absolute lymphocyte count (ALC, p

Background

The RAS-MAPK pathway is altered in ~40% of all human cancers, yet its therapeutic inhibition has been limited by adaptive resistance, paradoxical activation, and poor CNS penetration. NST-628 is a potent non-degrading fully brain penetrant pan-RAF-MEK molecular glue that leads to inactive complex formation between MEK and all isoforms of RAF preventing activation of MEK by RAF resulting in broad anti-tumor activity preclinically. We report preliminary findings from the first-in-human Phase 1a/b study of NST-628 in pts with RAS-MAPK-altered cancers.

Methods

NST-628-001 is an open-label Phase 1a/b study evaluating the safety, pharmacokinetics, and preliminary efficacy of oral NST-628 in pts with refractory metastatic/advanced solid tumors with K/NRAS or RAF mutations. Dose escalation employed BOIN method, with accelerated titration. Longitudinal PK and PD were analyzed. Tumor assessments were performed with RECIST 1.1 for primary extracranial solid tumors, and with RANO 2.0 for CNS malignancies.

Results

As of 02/01/2026, NST-628 has been administered to 64 pts across 7 dose regimens in the dose-escalation phase and to 5 pts in the expansion phase. Most common tumors were melanoma (48%), pancreatic (14%) and colorectal (8%) cancer. Median age was 65 yrs (range 18-89); median number of prior lines of systemic therapy was 2 (range 1-8). Most common treatment related adverse events (TRAEs) included rash, diarrhea, CK elevations and retinopathy. Majority of TRAEs were Grade (G) 1-2. Most common ≥G3 TRAEs were CK elevations (N = 6) and diarrhea (N = 3). No G5 TRAEs. The PK of NST-628 was characterized by apparent clearance of 0.143 L/hr. Exposure was dose-proportional at doses < 0.4 mg, and > dose-proportional at ≥ 0.4 mg. MTD was 0.4 mg QD and recommended dose for expansion (RDE) was 0.4 mg QD x7 followed by 0.3 mg QoD. At the RDE in response-evaluable BRAF Class II/III or NRAS mutant melanoma (N = 13) response rate (RR) was 38% (one response unconfirmed); across all doses (N = 28), RR was 29% (two responses unconfirmed at data cutoff). With median follow-up of 6.4 mo. median duration of response in melanoma was not reached. In addition to melanoma, responses were observed in ovarian, cervical, thymic and colorectal cancer. Baseline ctDNA confirmed driver mutations in 86% of pts and on treatment measurements correlate changes in ctDNA with radiographic response.

Conclusions

NST-628 showed a manageable safety profile in pts with advanced solid tumors and promising anti-tumor activity in previously treated BRAF Class II/III or NRAS-mutant melanoma and other RAS/RAF-driven malignancies. Beyond positioning NST-628 as a promising new therapy for pts with melanoma, the safety profile and anti-tumor activity support evaluation as monotherapy and in rational combinations in other patients with RAS-RAF-driven tumors.

Background:

Wildfires are becoming more frequent and severe, reversing decades of progress in reducing fine particulate matter (PM2.5) in the United States. Although wildfire smoke (WFS) contains numerous carcinogens and toxicants, its association with cancer incidence remains unclear.

Methods:

We examined associations between WFS exposure and cancer incidence in the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial. The PLCO trial prospectively assessed cancer incidence from enrollment (1993-2001) through 2018. WFS exposure was quantified monthly at participants’ residences using near-ground WFS PM2.5, WFS black carbon (BC), and satellite-derived WFS plume-day counts from 2006 until first cancer diagnosis or last contact. Guided by evidence that three years of air- pollution exposure can influence the development of EGFR-positive lung adenocarcinoma, WFS exposure was modeled as a time-varying variable using 36-month moving averages preceding each month. Hazard ratios (HRs) were estimated using Cox proportional hazards models stratified by study center, with proportional hazards assumptions verified. Restricted cubic splines were applied to evaluate dose-response relationships. Covariates included age, sex, race and ethnicity, education, smoking history, body mass index, and trial arm.

Results:

Among 91,460 PLCO participants with linked WFS exposure data, we identified incident cases of 1,758 lung, 800 colorectal, 1,739 breast, 242 ovarian, 896 bladder, and 1,696 hematopoietic cancers, and 1,127 melanoma during 2006-2018. Median (range) 36-month moving-averages were 0.37 (0.0083-1.72) μg/m3 for WFS PM2.5, 0.0083 (0.00- 0.21) μg/m3 for WFS BC, and 1.94 (0.097-7.18) days for monthly WFS plume-day counts. Restricted cubic splines indicated statistically significant associations (P

SAN DIEGO, USA—Pathology slides hold the key to distinguishing precisely which patients with metastatic non-small cell lung cancer can respond well to immune checkpoint inhibition monotherapy from those who need a combination of immunotherapy with chemotherapy, according to a research study discussed at the 2026 Annual Meeting of the American Association for Cancer Research.

In the study, immune signatures recognized by an artificial intelligence-driven “pathomics framework”, were able to assess risk scores to precisely inform survival prediction, according to first author of the study, Rukhmini Bandyopadhyay MD, a postdoctoral fellow at the University of Texas MD Anderson Cancer Center in Houston, USA. She gave more of the details to our reporter Peter Goodwin:

Background:

Immune checkpoint inhibitors (ICIs) have improved survival in non-small-cell lung cancer (NSCLC), yet only a subset of patients benefits, and biomarkers like PD-L1 remain limited. Here, we introduce a deep learning-based pathomics framework that utilizes routine H&E-stained slides to predict therapeutic response and survival outcomes in ICI-treated metastatic NSCLC.

Methods:

The study included 797 ICI-treated NSCLC patients from MD Anderson, with external validation in 280 patients from Mayo Clinic, Gustave Roussy, and the Phase III ICI-naïve LUSC Lung-MAP S1400I trial receiving nivolumab with or without ipilimumab. Path-IO (Pathology-Driven Immunotherapy Optimization) comprised of four major steps: (1) pathologist-verified tissue classifier segmented WSIs into eight compartments— Background, Bronchi, Immune, Lung, Necrosis, Stroma, Tumor, and Vessel—and was validated on TCGA and CPTAC dataset; (2) a survival prediction module generating patient-level risk scores in the MD Anderson cohort and validated across external datasets; (3) integration of Path-IO risk scores with radiomics and clinical features to improve prognostic accuracy; and (4) biological interpretability analyses correlating Path- IO risk immune contexture from multiplex immunofluorescence and transcriptomic signatures from NanoString profiling.

Results:

Path-IO effectively stratified patients into high and low-risk groups with significant survival differences. In the MD Anderson cohort, it achieved HR = 2.11 (p < 0.001) and HR = 2.51 (p < 0.001) for OS in the discovery and validation sets, and HR = 2.34 (p < 0.001) and HR = 1.87 (p < 0.001) for PFS, respectively. In the multicenter Phase III Lung- MAP S1400I trial, Path-IO achieved HR = 1.78 (p = 0.016) for OS and HR = 2.76 (p = 0.006) for PFS. In external validation, it predicted outcomes in the Gustave Roussy (OS = 1.97, p = 0.003; PFS = 1.51, p = 0.046) and Mayo Clinic (OS = 2.46, p = 0.007; PFS = 2.45, p = 0.027) cohorts. Path-IO outperformed PD-L1 and remained an independent predictor in multivariate analysis (p < 0.001). It enabled data-driven frontline selection between anti-PD-1 monotherapy and chemo-immunotherapy, offering guidance toward more personalized treatment decisions. Integration with radiomics and clinical features further improved predictive accuracy (OS 0.63→0.75; PFS C-index 0.58→0.70), while high Path-IO risk scores correlated with immune-cold phenotypes identified by multiplex immunofluorescence and NanoString transcriptomics.

Conclusions:

Path-IO demonstrates that deep learning models rooted in histopathologic

architecture can generate interpretable and biologically informed survival predictions in NSCLC treated with ICIs. By integrating pathology, radiology, and clinical data, Path-IO provides complementary predictive value beyond established biomarkers such as PD-L1.

PRESS RELEASE:

A Deep Learning Pathomics Platform May Help Predict Response to Immunotherapy in Lung Cancer Patients

SAN DIEGO – A biology-guided artificial intelligence model applied to routine pathology slides accurately predicted outcomes and response to immunotherapy in patients with metastatic non-small cell lung cancer (NSCLC), according to a study presented at the American Association for Cancer Research (AACR) Annual Meeting 2026, held April 17-22.

“Immunotherapy has transformed cancer treatment, but only a subset of patients benefit from it, and predicting who will respond remains challenging,” said presenter Rukhmini Bandyopadhyay, PhD, a postdoctoral fellow at The University of Texas (UT) MD Anderson Cancer Center. “While routine pathology slides contain rich information about the tumor and its surrounding environment, the large amount of complex data can be difficult for human experts to fully quantify.”

Pathomics is an emerging field that applies computational and machine learning methods for high- throughput analysis of digital pathology images to extract and analyze large-scale data related to cell and tissue architecture that can be linked to disease outcomes.

Bandyopadhyay and colleagues developed a pathomics framework based on a deep learning survival prediction model called Pathology-driven Immunotherapy Optimization or Path-IO, which can analyze pathology slide images and study patterns across the tissue to help identify patients who are most likely to benefit from immunotherapy.

“The core idea was to identify specific features, known as niches, within the tumor microenvironment to understand how tumors and the surrounding tissues are organized,” said Bandyopadhyay, adding that the model then combines this information with available imaging and clinical data to estimate whether a patient may have a higher or lower risk of poor outcomes from immunotherapy.

The researchers tested the platform in a study that included 797 immune checkpoint inhibitor-treated NSCLC patients from UT MD Anderson, with external validation in 280 additional patients from Mayo Clinic, Gustave Roussy, and the phase III Lung-MAP S1400I trial in which immunotherapy-naïve patients with lung squamous cell carcinoma (a subtype of NSCLC) were treated with immune checkpoint inhibitors.

Study results showed that the model could reliably stratify patients into higher and lower risk groups with significantly different outcomes. In the UT MD Anderson cohort, patients in the high‐risk group had more than double the risk of death or disease progression compared with patients in the low‐risk group. Comparable results were obtained in the validation datasets.

Model performance was evaluated using the concordance index (C-index), which measures how well each biomarker distinguishes between patients with different outcomes, explained Bandyopadhyay. Notably, Path-IO consistently outperformed PD-L1, the U.S. Food and Drug Administration-validated standard-of-care biomarker for guiding immunotherapy use in NSCLC patients, across both discovery and test cohorts. “PD-L1 alone showed limited prognostic performance, with C-indices of 0.58 for overall survival (OS) and 0.57 for progression-free survival (PFS) in the discovery cohort, declining to 0.50 and 0.51, respectively, in the test cohort. In contrast, Path-IO demonstrated stronger discriminative ability, achieving C-indices of 0.69 for OS and 0.65 for PFS in the discovery cohort and 0.63 for OS and 0.58 for PFS in the test cohort.”

Furthermore, combining pathology-based predictions with radiomics and clinical data further improved the model’s ability to distinguish patient outcomes, with the C-index increasing from 0.58 to 0.70 for PFS and from 0.63 to 0.75 for OS. “These observations highlight the value of integrating multiple sources of information to guide treatment decisions,” said Bandyopadhyay.

Bandyopadhyay explained that, unlike prior pathomics studies, Path-IO is a biology-guided approach that grounds the predictions in tissue structures that are familiar to clinicians to reflect how pathologists naturally interpret tissue.

The model’s predictions correlated with immune profiling and multiplex imaging data because higher risk scores assigned by the model corresponded to phenotypes that are less likely to be sensitive to immunotherapy. “This correlation provides biological evidence for why certain patients may have better or worse outcomes with immunotherapy,” added Bandyopadhyay.

Bandyopadhyay emphasized that, since this approach was designed to be applied to routine pathology slides, if validated as a predictive tool, it could be incorporated into existing clinical workflows without significant expense compared to other emerging data-based technologies.

“This study represents, to our knowledge, the first deep learning-based pathomics biomarker rigorously validated across international real-world cohorts and a phase III randomized clinical trial, directly addressing one of the most urgent unmet needs in precision oncology: reliable patient selection and stratification for immunotherapy,” said Bandyopadhyay.

Limitations of the study, according to Bandyopadhyay, include that the study design is retrospective in nature and, although the results suggest that Path-IO may have predictive value in certain patient subgroups, further investigation is critically needed to go beyond the identification of patients who would benefit from immunotherapy and help predict what type of immunotherapy they can benefit from. “Future directions include prospective validation and the integration of paired, more comprehensive molecular profiling to enhance predictive performance and provide deeper molecular insights,” said Bandyopadhyay.

Abstract

PURPOSE: Presence of circulating tumor DNA (ctDNA) is strongly associated with recurrence risk in early triple-negative breast cancer (TNBC). NSABP B-59/GBG-96-GeparDouze evaluated atezolizumab or placebo added to neoadjuvant therapy (NAT) and as adjuvant therapy in 1,550 patients with stage II/III TNBC. A prospective ctDNA sub-study collected serial blood during the first two years after randomization. In the recent 2025 San Antonio Breast Cancer Symposium, we presented the primary endpoint demonstrating that post-surgery ctDNA positivity was associated with an ~30-fold higher risk of distant recurrence. Here, post- NAT correlation with pCR and distant recurrence is presented. METHODS: Blood was collected at baseline, at completion of NAT prior to surgery, 3-6 weeks post-surgery, and 12- and 24-months after randomization. Primary tumors were analyzed via whole-exome sequencing for variant discovery. For ctDNA detection, libraries containing 15-60 ng of cell-free DNA from plasma samples were hybridized to patient-specific probes to enrich variant-containing regions, then sequenced. The association of post-NAT ctDNA status with pathological complete response, pCR (ypT0/is, ypN0) status and distant recurrence-free interval (dRFI) was determined. Additionally, baseline plasma ctDNA concentration was analyzed by T stage and nodal status RESULTS: At baseline, ctDNA was detected in 153 of 160 patients (96%). ctDNA was detected in 14 of 155 (9%) patients after completion of NAT. Positive ctDNA status after NAT was associated with residual invasive disease at surgery, and positive predictive value for non-pCR was 85.7%. Among the 97 patients with pCR after NAT, 95 (97.9%) were ctDNA-negative prior to surgery. Post-NAT pre-surgery ctDNA status was strongly associated with dRFI, with an HR 10.2 (3.8- 27.3; p

Abstract Body:

Background: QLS5132 is a highly selective ADC composed of a humanized anti-CLDN6 hIgG1 antibody and a novel topoisomerase-1 inhibitor as cytotoxic payload via a hydrophilic cleavable linker LK1b, with a drug-to-antibody ratio of 8. QLS5132 showed an expanded therapeutic window and potent antitumor activity in PROC in preclinical studies.

Methods: The trial (NCT06932094) recruited pts with histologically or cytologically confirmed advanced PROC, who failed or had no standard therapy. Accelerated titration design and Bayesian optimal interval design were adopted in dose-escalation stage. QLS5132 was administered via intravenous infusion once Q3W at dose levels of 1.6 mg/kg, 3.2 mg/kg, 4.8 mg/kg, 5.6 mg/kg, and 6.4 mg/kg. Two dose levels would be selected in dose-expansion phase. The primary endpoints were safety.

Results:

As of Jan 21, 2026, 28 pts with advanced PROC were enrolled (ovarian cancers:26 pts, fallopian tube cancers:2 pts). The dose-escalation for the 6.4 mg/kg cohort was completed. Median age was 57.5 years. Ten (35.7%) pts received ≥5 lines of prior treatment, 25 (89.3%) pts received prior bevacizumab, and 22 (78.6%) pts received prior polyADP ribose polymerase inhibitors. Dose-limiting toxicity of grade 4 platelet count decreased occurred in one patient at 6.4 mg/kg dose level. Twenty-six (92.9%) pts experienced TEAEs (treatment-related, 92.9%). The most common TRAEs of any grade with incidence >50% were nausea (85.7%), anorexia (60.7%), anemia (53.6%), and weakness (53.6%). Alopecia, bone pain, back pain, hypoesthesia, and mucositis oral occurred in one (3.6%) patient, respectively. No interstitial lung disease, ocular toxicity, or febrile neutropenia occurred. Most gastrointestinal TRAEs were grade 1 or 2. Nine (32.1%) pts experienced grade ≥3 TRAEs. The hematological TRAEs of grade ≥3 occurred in 2 (66.7%) pts at 6.4 mg/kg dose level, and 5 (20.0%) pts at

Background: Oral premalignant lesions affect 5% of the global population with transformation rates of 1-8% in mild-moderate dysplasia and up to 36% in severe dysplasia. Current management via surgical excision yields 30-40% recurrence despite negative margins, with cumulative functional morbidity. While systemic PD-1 blockade demonstrated biological activity in oral dysplasia, immune-related toxicity precludes use in non-cancer populations. We hypothesized intralesional delivery would achieve immune remodeling while eliminating systemic exposure. We conducted a phase 1, open-label, dose- escalation trial of intralesional nivolumab in patients with histologically confirmed oral epithelial dysplasia (NCT05327270). Twenty-nine patients received 10 mg or 20 mg intralesional nivolumab every three weeks for four cycles. Primary endpoints were safety and tolerability; secondary endpoints included lesion response, progression to carcinoma, pharmacokinetics, spatial immune profiling, and, uniquely for this population, prospective patient-reported outcomes (PROs). No dose-limiting toxicities occurred; 94% of adverse events were grade 1-2 with no systemic immune-related toxicities. Plasma nivolumab concentrations remained 10-fold below IV dosing without accumulation. Lesion area decreased 60% across cohorts with 41% histologic downgrading. Twelve-month cancer- free survival was 75.8%; all progression events were detected early and surgically salvageable. We performed the first prospective longitudinal analysis of PROs in oral premalignancy. High study completion (86%) and adherence, despite significant travel burden, coupled with stable or improved quality-of-life scores (specifically pain and swallowing), indicate that repeated intralesional injections are a feasible, non-toxic approach associated with no functional adversity. Unlike surgical standards that degrade function, this strategy preserved patient quality-of-life. Mechanistic analyses using spatial transcriptomics (Xenium) and multiplexed imaging (CODEX) revealed immune activation exclusively in treated lesions: increased CD4+ and CD8+ T cell infiltration, enriched CCR7+ activated dendritic cells, elevated CD103+ tissue-resident CD8+ T cells, and formation of higher-order immune assemblies. Untreated non-index lesions from the same patients showed no immune changes, definitively demonstrating anatomically restricted immune activation. PBMC profiling confirmed absence of systemic immune perturbation.

This first-in-class trial demonstrates intralesional PD-1 blockade safely reprograms premalignant tissue immunity without systemic perturbation, establishing lesion-directed checkpoint inhibition as a viable cancer interception strategy. These findings have established the foundation for a randomized, placebo-controlled Phase 2 trial currently enrolling at MD Anderson Cancer Center (NCT06561087) and support broader applicability to accessible epithelial precancers including cervical, anal, and cutaneous dysplasia.

PRESS RELEASE:

Intralesional Nivolumab May Be Effective Against Precancerous Oral Lesions

The treatment preserved quality of life

SAN DIEGO – Injecting nivolumab (Opdivo) directly into precancerous oral lesions led to reduction in lesion size and allowed some patients to avoid surgery, according to research from a phase I clinical trial presented at the American Association for Cancer Research (AACR) Annual Meeting 2026, held April 17- 22.

Approximately 5% of the general population have precancerous lesions in their mouth that can carry a 1% to 36% risk of progression to oral cancer, depending on the extent of dysplasia (i.e., how abnormal the cells of the lesion are) and other factors, explained presenter Moran Amit, MD, PhD, a surgeon and assistant professor at The University of Texas MD Anderson Cancer Center. Since there are no reliable biomarkers to predict the risk of progression, many patients typically undergo surgical resection of their lesions, but this procedure is associated with high morbidity, he said.

“The mouth is the main conduit to so many different functions, including speaking, eating, drinking, and breathing. Think about the last time you had a sore spot in your mouth, how debilitating that was. Now imagine a patient who has to undergo surgery at many locations in their mouth, over and over again as the lesions recur,” said Amit, noting that about 60% of patients present with multiple lesions and that the risk of recurrence after surgery can be as high as 40%.

“Each time a patient has to undergo surgery, they are losing volume of their oral cavity, most commonly on the tongue. Once you lose a certain amount of your tongue, you cannot articulate anymore, you cannot swallow effectively,” he added. “Because of precancerous lesions, patients can lose their ability to speak and eat. The objective of our study was to find a way to spare patients from this oftentimes debilitating surgery.”

Prior research has indicated that treatment with the immune checkpoint inhibitor nivolumab could reduce the size and progression risk of precancerous oral lesions, but this treatment, which is delivered systemically through intravenous infusion, comes with severe toxicities, said Amit.

“While effective, systemic nivolumab can lead to toxicities that would not be acceptable for patients who do not even have cancer yet,” he noted.

Amit and colleagues reasoned that injecting a lower dose (2% to 4% of the intravenous dose) of nivolumab directly into the oral lesion could effectively treat the lesion without inducing the systemic toxicities associated with intravenous nivolumab.

To test this hypothesis, they conducted a phase I clinical trial to evaluate the safety and efficacy of intralesional nivolumab.

The trial enrolled 29 patients with at least one histologically confirmed, untreated premalignant oral lesion that had a high risk of progression to oral cancer due to its size, location, morphology, or extent of dysplasia, or the patient’s age or medical history. More than half of the lesions were located on the tongue. Fifteen patients had lesions with high-grade (moderate or severe) dysplasia; the remaining 14 patients had low-grade (mild) dysplasia.

Patients received either 10 mg or 20 mg of nivolumab injected directly into one of their oral lesions every three weeks for a total of four cycles. The trial protocol allowed treatment of only one lesion per patient in order to assess whether intralesional nivolumab’s effects would be systemic or restricted to the site of injection. In instances where patients had more than one lesion, the largest lesion was chosen for treatment.

After a median follow-up of 14.5 months after the first injection, 25 of 29 patients (85%) had experienced a clinical response, defined as a decrease in lesion size. Lesion area decreased by an average of 60%, and 19 patients experienced reductions greater than 50%. Clinical responses were observed for lesions that were high-grade and those that were low-grade at baseline. Twelve patients (41%) experienced histologic downgrading of their treated lesion, and six patients had complete pathologic response, meaning their treated lesion had no signs of dysplasia at the time of follow-up. Of the six patients with complete pathologic response, four had moderate dysplasia before treatment, and two had mild dysplasia.

Twelve months after treatment, 82.13% of treated lesions continued to be cancer free. For the six patients whose treated lesions progressed to cancer, the progressions were detected early, and the lesions were surgically removed. None of the patients whose lesions didn’t progress required or opted for surgical resection of their treated lesions during the follow-up time.

Serum levels of nivolumab were consistently 10-fold lower than typically observed with systemic administration. No dose-limiting toxicities occurred with intralesional treatment. The most common adverse events were fatigue, diarrhea, and rash. Mild injection-site reactions occurred in 40% of injections but resolved within 48 hours without intervention. Most adverse events were grade 1 or 2, but there was one case each of grade 3 diarrhea, grade 3 hyperglycemia, and grade 4 acidosis.

All but four enrolled patients completed all treatment cycles and monitoring. Patients’ symptoms, such as those related to swallowing, mouth and throat soreness, voice, communication, taste, and nutrition, either improved or remained stable during treatment and follow-up, according to patient-reported outcomes. Patients reported greater enjoyment of life and increased physical activity after treatment as compared with baseline.

The researchers also examined tissue samples from 23 patients to determine how intralesional nivolumab impacted the immune microenvironment of treated and untreated lesions. They observed immune activation exclusively in the treated lesions, as indicated by greater infiltration of CD4+ T cells, CD8+ T cells, and activated dendritic cells, as well as immune-cell interactions indicative of adaptive immune responses. Untreated lesions from the same patients did not exhibit immune changes, which, according to Amit, suggests that intralesional delivery effectively limited nivolumab’s function to target sites.

“Our findings demonstrate that intralesional delivery of nivolumab is safe, well tolerated, and results in efficacy rates unparalleled by other nonsurgical methods, which allowed us to spare surgery for the majority of patients—spare removal of pieces of their mouth, whether it’s the tongue, the cheek, the floor of their mouth, or their palate,” said Amit. “Even if a patient ends up undergoing surgery later, the average 60% reduction in lesion size from intralesional nivolumab means we can substantially minimize the amount of surgery they’ll need down the road, which would hopefully translate to a much lower impact on their quality of life.”

Amit noted that the findings may have implications beyond oral lesions. “Many cancer types are preceded by precursor lesions, such as those arising on the skin, cervix, or colon. Our results raise the possibility that local immunotherapy administration could be an effective interception strategy for those precancerous lesions as well.”

Limitations of the study include the single-arm design, short follow-up time, and the fact that the study was not statistically powered to assess efficacy.

The study was supported by the Cancer Prevention and Research Institute of Texas. Amit declares no conflicts of interest.

Background:

Elisrasib is a next-generation KRAS-G12C inhibitor (G12Ci) designed to improve target engagement (TE) efficiency and overcome growth factor-induced nucleotide exchange. This unique MoA distinguishes elisrasib from first-generation G12Ci and has led to robust anti-tumor activity in G12Ci-naïve/-resistant PDX models. Ph1 results demonstrated favorable safety and promising efficacy across NSCLC, CRC and PDAC. Here, we present updated findings in previously treated locally advanced or metastatic NSCLC patients (pts) (naïve and refractory to G12Ci) from the ongoing Ph1/2 trial (NCT05410145).

Methods: Pts with locally advanced or metastatic KRAS G12C-mutated NSCLC were eligible. All pts must had received at least one prior line of systemic treatment, including IO and/or platinum doublet chemotherapy. For G12Ci-refractory pts, they were required to have radiologically or clinically documented PD following a KRAS G12Ci. Elisrasib was administered orally QD in 21-day cycles at 6 planned dose levels (50-900mg) in the dose escalation and 600mg was selected as the treatment dose for expansion cohorts. The key objectives included safety, efficacy, and ctDNA kinetics by liquid biopsy (Guardant360® CDx or OncoCompass® Target). Results: As of 06 Jan 2026, total 165 NSCLC pts across 9 countries received elisrasib monotherapy (2 in 50mg, 5 in 100mg, 4 in 200mg, 6 in 400mg, 144 in 600mg and 4 in 900mg). Median study follow up time for 2L+ G12Ci-naive and G12Ci-refractory NSCLC were 11.3m and 10.6m, respectively. TRAEs of any grade occurred in 143/165 (87.9%) pts, ≥G3 TRAEs occurred in 19/165 (11.5%) pts. The safety profile in NSCLC pts is comparable with overall population. In 2L+ G12Ci-naïve NSCLC (50-900mg QD), 84 pts were evaluable for efficacy. ORR was 57.1% (48/84) with 1 CR and DCR of 98.8%. mPFS, mDOR and 12m OS rate (OS was not matured) were 8.8m, 12.5m, and 67%, respectively. At 600mg QD (68 evaluable pts), ORR was 55.9% (38/68) with 1 CR and DCR of 98.5%. mPFS, mDOR and 12m OS rate (OS was not matured) were 11.8m, 14.9m, and 71%, respectively. In 2L+ G12Ci-refractory NSCLC (600mg QD), 31 pts were evaluable for efifcacy. ORR was 32.3% (10/31) and DCR of 83.9%. mPFS, mDOR and 12m OS rate (OS was not matured) were 8.1m, 8.2m, and 69%, respectively. PK at 600mg QD achieved Ctrough exposure (5.6 nM) which was 5x greater than required exposure (1 nM) for complete TE. Baseline ctDNA G12C+ was detected in 68% (54/80, 4 pts were excluded due to incomplete data) of G12Ci-naïve and 68% (21/31) G12Ci- refractory pts, with 93% (50/54) and 76% (16/21) achieved molecular response (≥90% G12C MAF reduction), respectively. Notably, 4/5 G12Ci-refractory pts with G12C amplification, a known resistant MoA, showed tumor shrinkage, including three achieved cPR.

Conclusions:

Elisrasib monotherapy demonstrates robust and durable efficacy and favorable tolerability in 2L+ NSCLC pts, naïve and refractory to G12Ci.

PRESS RELEASE

SAN DIEGO – Treatment with the investigational next-generation KRAS-G12C inhibitor elisrasib led to clinical benefit in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) whose tumors harbored a KRAS G12C mutation and whose disease progressed after prior therapies, according to results presented at the American Association for Cancer Research (AACR) Annual Meeting 2026, held April 17-22.

The G12C mutation is the most common KRAS alteration in NSCLC. Two first-generation inhibitors targeting this mutation, sotorasib (Lumakras) and adagrasib (Krazati), have been approved by the U.S. Food and Drug Administration (FDA) for treatment of this patient population. However, these drugs benefit only approximately 30% of patients, half of whom experience disease progression within six months, and safety remains a challenge in the clinic, explained Byoung Chul Cho, MD, PhD, a professor in the Division of Medical Oncology, Yonsei Cancer Center, Yonsei University College of Medicine in Korea, who presented the study.

“Research is now focused on next-generation inhibitors aiming for safer, more effective, and longer- lasting results,” said Cho. “These new treatments may address challenges such as brain metastases and resistance to earlier drugs, potentially improving outcomes and redefining care for lung cancer patients with KRAS G12C mutations.”

Similar to the first-generation KRAS inhibitors, elisrasib selectively binds to mutant KRAS G12C and locks it in its inactive state, thus inhibiting its oncogenic function. However, elisrasib was designed for faster and stronger target engagement, resulting in sustained inhibition, Cho explained.

Safety and efficacy of elisrasib alone and in combination with other drugs are being tested in an ongoing phase I/II clinical trial in patients with KRAS G12C-mutant solid tumors. Early data from a subgroup of NSCLC patients showed promising results.

The new analysis included a larger cohort of 165 patients with locally advanced or metastatic NSCLC who were previously treated with immunotherapy and/or chemotherapy. Some of them also received first- generation KRAS G12C inhibitor therapy and experienced progressive disease. Elisrasib was administered orally once daily in 21-day cycles at six dose levels ranging from 50 to 900 mg, and 600 mg was selected as the recommended treatment dose.

Median follow up time was 11.3 months in patients who had not been previously exposed to KRAS G12C inhibitor therapy (naïve) and 10.6 months in patients with G12C inhibitor-refractory disease. Grade 3 and higher treatment-related adverse events were observed in 11.5% of patients. “Elisrasib demonstrated a favorable safety and tolerability profile,” said Cho.

The efficacy analysis included 84 participants who were naïve for KRAS G12C inhibitor therapy and 31 with KRAS G12C inhibitor-refractory disease. Among the naïve cohort, for patients treated at the recommended dose of 600 mg, overall response rate and disease control rate were 58.8% (including one complete response) and 98.5%, respectively. Median progression-free survival (mPFS) was 12.2 months; median duration of response (mDoR) and overall survival (OS) rate at 12 months were 16.5 months and 72%, respectively. “In our study, elisrasib demonstrated a significantly higher response rate and prolonged tumor responses than first-generation KRAS G12C inhibitors, indicating that its molecular design may be translating into improved clinical outcomes for patients,” said Cho. He added that elisrasib has received Fast Track and Breakthrough Therapy designations from the FDA for the indication of second-line therapy in KRAS G12C inhibitor-naïve patients.

Among patients who experienced disease progression on earlier KRAS G12C inhibitor therapy, all of whom were treated at the 600 mg elisrasib dose, overall response rate was 32.3%, and disease control rate was 83.9%. Further, mPFS, mDoR, and OS rate at 12 months were 8.1 months, 15.6 months, and 71%, respectively. Tumor responses were also observed in patients with brain metastases, a difficult-to- treat population, said Cho.

KRAS G12C-positive circulating tumor (ctDNA) was detected in 70% of patients before treatment. Molecular responses, defined as reductions of 90% or greater in the fraction of KRAS G12C-mutant ctDNA, were observed with elisrasib in 93% of G12C inhibitor-naïve patients and 80% of those whose disease had progressed on previous G12C inhibitor therapy.

“Among patients whose disease progressed on first-generation inhibitors, we found five cases of KRAS gene amplification, an important mechanism of evasion of KRAS G12C inhibitor efficacy,” said Cho. “Out of those five KRAS amplification cases, four experienced tumor shrinkage, three showed a clinical response, and the disease control rate was 100%, indicating elisrasib’s effectiveness in this biomarker- defined group.”

Cho added, “Elisrasib demonstrates the ability to provide deeper, longer-lasting tumor responses, even in cases where first-generation KRAS G12C inhibitors failed. Overall, these findings indicate that elisrasib may significantly improve treatment for lung cancer patients with KRAS G12C mutations.”

Commenting on the limitations of the study, Cho said that it was an early-phase, single-arm trial, so its primary purpose was to assess safety and early efficacy and establish the correct dose. “Although the safety and initial efficacy findings are encouraging, larger randomized studies are necessary to confirm effectiveness and tolerability. Additionally, longer follow-up will be crucial for evaluating how durable the responses truly are.”

Background:

DKY709 is an orally administered molecular glue degrader of IKZF2, a transcription factor expressed in regulatory T cells. PDR001 (spartalizumab) is a humanized monoclonal antibody directed against programmed cell death 1 protein (PD-1). This phase 1 study was designed to assess the safety, pharmacokinetics, and preliminary efficacy of DKY709 as monotherapy or in combination with PDR001 in patients with advanced solid cancers. Methods:

DKY709A12101C (NCT03891953) was a global, phase 1, open-label study in patients with advanced cancers, including non-small cell lung cancer (NSCLC) and melanoma previously treated with anti-PD-1/PD-L1 therapy, or previously treated nasopharyngeal carcinoma (NPC). Patients received DKY709 alone (arm A) or in combination (arm B) with PDR001 (400 mg Q4W or 300 mg Q3W intravenously). During dose escalation, 20 mg was the starting dose and patients also received 4, 6, 10, or 40 mg (arm A only) of DKY709 by mouth QD continuously. An intermittent dosing schedule for DKY709 (20 or 10 mg) of either 3 or 2 weeks on followed by 1 week off was implemented in both arms. Primary endpoints were safety and tolerability. Secondary endpoints included pharmacokinetics, pharmacodynamics, and preliminary antitumor activity. Results:

At data cutoff (Sep 5, 2024), 58 patients were treated with DKY709 (30 with melanoma, 4 with NPC, and 24 with NSCLC) and 40 with DKY709 + PDR001 (12 with melanoma, 13 with NPC, and 15 with NSCLC). Median age was 60 years; 46% of participants were female. DKY709 showed dose-proportional exposure with 2- to 3-fold accumulation and achieved IKZF2 degradation of ≥90% in peripheral regulatory T cells with all doses ≥6 mg. Dose-limiting toxicities occurred in 3 patients receiving monotherapy and 2 receiving the combination. The most common treatment-related adverse events were myalgia (17.2%) with DKY709 monotherapy and AST/ALT increase (22.5%) and diarrhea (22.5%) with DKY709 + PDR001. Reversible peripheral neuropathy related to DKY709 was observed in 28% and 30% of patients receiving monotherapy and the combination, respectively; lower doses and intermittent schedules were associated with less neurotoxicity. The disease control rate in the monotherapy arm was 44.8% and included 1 confirmed complete response (melanoma) and 3 confirmed partial responses (2 melanoma and 1 NSCLC). The disease control rate in the combination arm was 37.5% and included confirmed partial responses in 5 patients (2 melanoma, 2 NPC, and 1 NSCLC). The recommended dose for expansion was 6 mg QD continuously in the monotherapy and combination arms. Conclusions:

DKY709 achieved IKZF2 degradation of ≥90% in peripheral regulatory T cells at doses ≥6 mg. DKY709 as monotherapy and in combination with anti-PD-1 therapy reduced tumor volume in patients with NPC and those with NSCLC and melanoma previously treated with immunotherapy.

BARCELONA, Spain—More evidence has emerged showing that older women with breast cancers that are not life threatening can safely receive only radiotherapy after breast conserving therapy, without adding hormone treatments. At the 2026 European Breast Cancer Conference emerging findings from the EUROPA study of women over 70 with “luminal-like” early breast cancer were discussed by Icro Meattini MD, Associate Professor of Radiotherapy at the University of Florence, and Clinical Oncologist at Azienda Ospedaliero-Universitaria Careggi, University of Florence, Italy.

2026 European Breast Cancer Conference:

“EUROPA Study: Endocrine or Radiation Therapy for Elderly Patient with Small Early Breast Cancers, Luminal A-like”

(Follow up from SABCS interim findings report (2024))

DETAILS:

At SABCS 2024, Dr. Icro Meattini presented a preplanned interim analysis of the EUROPA trial, a randomized phase III study comparing exclusive endocrine therapy (ET) vs. radiation therapy (RT) in women aged 70+ with luminal-like early breast cancer. The study aimed to evaluate quality of life (HRQOL) and ipsilateral breast tumor recurrence (IBTR) to guide treatment decisions in this patient population.

Key Findings:

RT preserved HRQOL scores better than ET at 24 months (mean change: -3.4 RT vs. -9.79 ET, p=0.045).

Treatment-related adverse events (AEs) were lower in the RT arm (67%) compared to the ET arm (85.4%).

No significant differences in IBTR rates at this interim analysis, but longer follow-up is needed for definitive conclusions.

RT showed better functional outcomes compared to ET across multiple QLQ-C30 domains

Clinical Implications:

These results suggest that both RT and ET may be viable single-modality treatment options in this population, with HRQOL and toxicity profiles playing a key role in treatment selection. The study underscores the importance of multidisciplinary, patient-centered approaches in older women with early-stage breast cancer.

2024 EUROPA Findings:

Looking back at SABCS 2024, the EUROPA trial continues to provide valuable insights into optimizing treatment decisions for older breast cancer patients.

Background

Optimal therapy following breast-conserving surgery in older adults with low-risk, early-stage breast cancer remains uncertain. The EUROPA trial aims to compare the effects of radiotherapy and endocrine therapy as single-modality treatments on health-related quality of life (HRQOL) and ipsilateral breast tumour recurrence (IBTR) outcomes in this population.

Methods

This non-inferiority, phase 3, randomised study was conducted at 18 academic hospitals across Italy (17 centres) and Slovenia (one centre). Eligible patients were women aged 70 years or older with histologically confirmed, stage I, luminal A-like breast cancer, who had undergone breast-conserving surgery and had an Eastern Cooperative Oncology Group performance status of 0 or 1. Patients were randomly assigned (1:1) to receive single-modality endocrine therapy or radiotherapy. Endocrine therapy consisted of daily oral aromatase inhibitors or tamoxifen, for a total planned duration of 5–10 years as per clinical discretion, while radiotherapy was administered as either whole breast or partial breast irradiation, delivered in 5–15 fractions. Randomisation was stratified by health status according to the Geriatric 8 (G8) screening tool and by age, with allocation concealed and no blinding. The co-primary endpoints were the change in HRQOL, assessed by the global health status (GHS) scale of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire 30-item core module at 24 months, and 5-year IBTR rates (not reported here). This preplanned interim analysis was performed once at least 152 patients completed the 24-month GHS HRQOL assessment. The safety population comprised patients who received the study intervention at least once after randomisation. The study is registered with ClinicalTrials.gov, NCT04134598, and is ongoing and actively recruiting.

Findings

Between March 4, 2021, and June 14, 2024, 731 women were randomly assigned to receive radiotherapy (n=365) or endocrine therapy (n=366). This analysis included 104 patients in the radiotherapy group and 103 in the endocrine therapy group, with a median follow-up of 23·9 months (IQR 22·9–24·2). Patients were predominantly White (204 [99%] of 207) and the median age was 75·0 years (IQR 73·0–80·0) in the radiotherapy group and 74·0 years (72·0–80·0) in the endocrine therapy group. 86 patients in the radiotherapy group and 75 in the endocrine therapy group completed the 24-month HRQOL assessment. The mean baseline GHS score was 71·9 (SD 19·1) in the radiotherapy group and 75·5 (19·3) in the endocrine therapy group. At 24 months, the age-adjusted, G8 score-adjusted mean change from baseline in GHS was –3·40 (95% CI –7·82 to 1·03; p=0·13) in the radiotherapy group and –9·79 (–14·45 to –5·13; p

BARCELONA, Spain—Early results from the ADARNAT study have found that using axillary radiotherapy after neoadjuvant therapy and surgery for women with sentinel node positive early breast cancer was as effective removing lymph nodes while bringing a lower risk of lymphedema. These preliminary finding were reported at the 2026 European Breast Cancer Conference by Amparo Garcia-Tejedor MD, PhD, Professor of Gynecology at the University of Barcelona’s Bellvitge Hospital, in Barcelona, Spain.

Background:

After neoadjuvant therapy (NAT), the optimal management of sentinel lymph node (SLN)-positive axilla remains controversial. Current guidelines still recommend axillary lymphadenectomy (ALND), although evidence increasingly supports less invasive approaches. The ADARNAT trial investigates whether axillary radiotherapy (ART) without lymphadenectomy can safely replace ALND in patients with limited nodal disease after NAT.

Methods:

ADARNAT is an open-label, randomized, phase III multicenter trial across 23 Spanish hospitals. Eligible patients had cT1–T4b, cN0–cN1 breast cancer treated with NAT (chemotherapy or endocrine therapy) and 1–2 positive SLNs (micro- or macrometastases) at surgery. Participants were randomized to ART (experimental arm) or ALND (control arm). Both arms received regional radiotherapy to level III axilla and supraclavicular and/or internal mammary nodes, plus breast/chest wall irradiation when indicated. This report summarizes pilot phase outcomes assessing feasibility and short-term safety.

Results:

From June 2021 to April 2023, 272 patients were enrolled; 102 completed per protocol (46 ART, 56 ALND) with a median follow-up of 2 years. Baseline and pathological characteristics were balanced between arms (Table). No axillary recurrences occurred in the ART arm and one in the ALND arm (1.8%, p=0.3). Distant metastases occurred in 4.4% vs 5.5% (p=0.8), and two deaths were reported in the ALND group (4.3%, p=0.2). Lymphedema was more frequent after ALND (26.7%) than ART (18.9%) without statistical significance (p=0.4). Two-year disease-free and overall survival rates were comparable, supporting the feasibility and short-term oncologic safety of ART.

Conclusions:

The ADARNAT pilot phase suggests that axillary radiotherapy may achieve similar short-term oncologic outcomes to axillary lymphadenectomy in SLN-positive breast cancer after NAT, with comparable toxicity and a trend toward reduced morbidity. These preliminary results support the continuation of the phase III trial to confirm long-term non- inferiority and potential quality-of-life benefits of omitting axillary surgery.

2026 EBCC PRESS RELEASE:

Radiotherapy rather than surgery may help reduce risk of lymphoedema in patients with breast cancer: results from pilot study

Barcelona, Spain: Patients with breast cancer may be able to avoid lymphoedema, which can occur after surgery to remove lymph nodes in the armpit (the axilla), by having radiotherapy instead.

New findings, presented at the 15th European Breast Cancer Conference (EBCC15) in Barcelona today (Thursday), suggest that axillary radiotherapy may be as effective at killing any remaining cancer cells, while being less likely to trigger lymphoedema – an often painful swelling of the arm and armpit.

These results come from the pilot phase of a phase III randomised international clinical trial [1, 2] that is investigating whether axillary radiotherapy (ART) has a lower risk of lymphoedema than axillary lymph node dissection (ALND) in patients with breast cancer who have received neoadjuvant systemic therapy, such as chemotherapy or hormone therapy, before surgery, and in whom cancer has spread to only one or two lymph nodes. The trial will also be looking at overall survival and disease-free survival.

The researchers stress that these are preliminary results from two years of follow-up in the pilot study, and that clinicians should wait for the results from the phase III part of the trial, which is ongoing, before considering changing clinical practice.

Professor Amparo Garcia-Tejedor, from the Functional Breast Unit at Bellvitge University Hospital, Spain, and the Institut Català d’Oncologia, is leading the trial. She told the conference that studies had already shown that ART was a good alternative to ALND in patients for whom the first line of treatment was surgery.

“In situations where patients have received chemotherapy or hormone therapy before surgery, it is expected that results could be similar,” she said. “However, robust prospective data are not yet fully established or published.

“Many patients treated with neoadjuvant therapy experience a significant reduction in axillary disease burden and ultimately present with only one or two lymph nodes that are positive for cancer metastases, which often correspond to the sentinel lymph node, while the remaining axillary nodes are negative. This observation strongly suggested that further axillary surgery might be unnecessary in a substantial proportion of patients and that a strategy of de-escalation should be explored.”

From June 2021 to April 2023, the ADARNAT trial (ALND vs ART in Positive Sentinel Node After Neoadjuvant Therapy in Breast Cancer) recruited 272 patients with breast cancer, which might have spread (metastasised) to one or more lymph nodes. The patients had received neoadjuvant therapy and, at the time of surgery, had metastatic cancer in one or two sentinel lymph nodes (the lymph nodes where cancer typically metastasises first). The patients were randomised to receive either ART or ALND; patients in both arms of the trial also received radiotherapy to areas of the breast and chest. Results were available for 46 patients in the ART group and 56 patients in the ALND group, with a median follow-up period of two years.

No cancer recurred in the axillary area in the ART group and one recurred in the ALND group (1.8%). Cancer metastasised to other parts of the body in 4.4% versus 5.5% of the patients, respectively, and there were two deaths in the ALND group (4.3%). Lymphoedema occurred more frequently after ALND (26.7%) than ART (18.9%), although this was not statistically significant. Disease-free and overall survival rates were similar after two years of follow-up.

Prof. Garcia-Tejedor said: “These results indicate that ART instead of ALND is feasible and has good cancer outcomes at two years.

“While some specialists have already begun to substitute axillary lymph node dissection with axillary radiotherapy without waiting for definitive results, the only way to determine with certainty whether this strategy is truly safe and effective is through participation in a well-designed clinical trial such as the one we are now conducting. This is particularly important given that the study population includes patients with residual axillary disease and, therefore, a potentially worse prognosis.

“In this context, treatment decisions should not be made without robust evidence. Our trial is designed to provide the necessary data to definitively answer this question and to ensure that any future change in standard practice is safe in terms of cancer outcomes and is also beneficial for patients.”

Dr Maria Laplana-Torres is a radiation oncologist at the Hospital Clínic de Barcelona, Spain. She presented results from the pilot phase of the trial that showed that although ART was associated with more damage to the skin from radiation, this tended to be transient and easily treatable.

Acute skin damage (grade 2 or above) occurred in 27.8% of ART patients compared with 13.3% after ALND. It consisted mainly of skin redness, pigment changes or skin peeling in some cases. There were no significant differences in later skin damage between the two groups.

She said: “Some patients experienced mild, temporary difficulty raising the arm above the shoulder or lifting it to the side. These limitations were usually short-lived and did not affect everyday activities.

“We found that treating the axilla with radiotherapy instead of extensive surgery can avoid a more aggressive operation without compromising treatment safety in patients with sentinel lymph node involvement. One and two years after treatment, there were no meaningful differences in arm mobility or quality of life between the two groups, although there was a more favourable trend in the ART patients. These results show that axillary radiotherapy may be a safe and less invasive option for some women treated with chemotherapy or hormone therapy before surgery.

“This kind of research is essential to continue improving patient outcomes and to define safer, equally effective therapeutic approaches.”

So far, more than 500 patients have joined the main, phase III clinical trial. The researchers estimate that approximately three more years will be required to complete patient recruitment. This will then be followed by the planned five years of follow-up to fully assess cancer outcomes.

Prof. Garcia-Tejedor concluded: “If the study confirms the safety and effectiveness of axillary treatment de-escalation, the implications for both patients and clinicians could be substantial. For patients, the main potential benefit would be an improvement in quality of life, particularly through a reduction in lymphoedema and other functional complications associated with axillary surgery. For clinicians, these findings would support a paradigm shift in axillary management, reinforcing the move away from routine extensive surgery toward more personalised and less morbid treatment strategies, while maintaining good cancer outcomes.

The Chair of EBCC15, Professor Isabel Rubio, Head of Breast Surgical Oncology at the Clínica Universidad de Navarra in Madrid, Spain, was not involved in this research. She commented: “These findings from the pilot phase of the phase III ADARNAT clinical trial are encouraging. They provide a sound basis for the clinical trial to proceed. Once the trial reports its final results in a few years’ time, we will know whether radiotherapy rather than surgery is safe for patients who have received neoadjuvant treatments.

“While this trial suggests a promising trend towards lower lymphoedema rates with radiation therapy, the next important step is to determine in which patients it may be safe to omit radiation altogether in order to further individualise breast cancer care. Surgical treatment for breast cancer has already moved towards de-escalation, with many patients now able to avoid full axillary lymph node dissection and its associated side effects. However, despite these advances, a significant number of patients still face an increased risk of lymphoedema after radiation therapy. Future research should focus on identifying the subgroup of patients who may not benefit from either axillary dissection or radiation therapy, thereby helping to minimise treatment-related complications while maintaining excellent cancer outcomes.”

Radiation Boost May No Longer Be Justified After Standard Therapy for Early Breast Cancer

An interview with:

Eline Verreck BSc, Erasmus University Medical Centre, Surgical Oncology Department, Rotterdam, The Netherlands

BARCELONA, Spain—Any benefit from an additional tumor-bed radiotherapy “boost” after completing standard therapy for early breast cancer seems no longer to be justified in this age of increasingly effective systemic treatments now being incorporated into standard breast-conserving therapy. A new study conducted in the Netherlands, with 34,504 patients followed up for a median of 8.3 years, has found that the possible small reductions of long-term local recurrence rates from using a boost no longer justify the toxicities such a boost can bring.

Findings were reported at the 2026 meeting of the European Breast Cancer Conference by Eline Verreck BSc, who is a PhD candidate at Erasmus University Medical Centre’s Department of Surgical Oncology in Rotterdam. She talked about her results with the Audio Journal of Oncology’s correspondent, Peter Goodwin:

BACKGROUND

The five-year results of the RAPCHEM study (De Wild et al, 2022) and the recently published NSABP-B51 trial (Mamounas et al, 2025) suggest that locoregional radiation therapy (RT) can be tailored to the ypN-status in cT1-2N+ breast cancer (BC) patients treated with primary systemic treatment (PST). However, long-term results are lacking. Here we present the 10-year results of the RAPCHEM study, a prospective registry study, evaluating the long-term safety of tailoring locoregional RT to the nodal response after PST, for locoregional recurrence rate (LRR), recurrence free interval (RFI) and overall survival (OS).

BARCELONA, Spain: Because low-risk ductal carcinoma in situ (DCIS) is often unlikely to progress to breast cancer, de-escalating therapy was on the agenda of the Lord trial of active surveillance, that was reported at the 2026 European Breast Cancer Conference. The findings were reassuring: So much so that randomization was stopped early. The lead study author, pathologist Jelle Wesseling MD PhD who is Medical Director of the Early Cancers Detection Centre at the Netherlands Cancer Institute in Amsterdam, gave the details to the Audio Journal of Oncology’s Peter Goodwin.

Background

Active surveillance has been proposed as a de-escalation strategy for women with low-risk ductal carcinoma in situ (DCIS). The LORD-trial evaluates the safety of active surveillance compared with standard treatment in women with estrogen-receptor-positive, HER2- negative, grade 1–2 DCIS.

Methods

The LORD-trial is a multicentre study that followed a patient-preference design after initial randomization proved infeasible. The primary endpoint is ipsilateral invasive breast cancer (iiBC)-free rate at 10 years. A prespecified, non-binding interim futility analysis was planned after 60 iiBC events.

Results

DSMB prespecified interim analysis

1,423 women had been enrolled with a median follow-up of 23 months. The first n=73 were randomized between the two arms. After transforming to a patient preference design, n=1,025 patients opted for active surveillance and n=330 for standard treatment. No patients received endocrine therapy. On an intention-to-treat basis, iiBC occurred in 4/363 (1%) women allocated to standard treatment and 63/1,060 (6%) women undergoing active surveillance. Based on these findings, the Data Safety Monitoring Board (DSMB) advised cessation of registration and recruitment, while continuing follow-up of enrolled patients.

Cohort analysis

When iiBCs detected at primary surgery in the standard-treatment group were additionally considered, cumulative iiBC incidence was similar between strategies: 33/363 (9%) in the standard-treatment arm and 63/1060 (6%) in active surveillance. Cases with full pathology characteristics available – for 31 and 55, respectively – were compared between the two arms (Table 1).

Conclusions

The prespecified DSMB interim analysis resulted in a recommendation to stop inclusion for reasons of futility, leading to early closure of trial inclusion. Follow-up of included women was recommended and is ongoing to assess long-term outcomes and inform the safety of de-escalation strategies for DCIS.

BARCELONA, Spain—Among patients being treated with neoadjuvant therapy for their early breast cancers, circulating tumor DNA performed better as an independent prognostic marker for predicting relapse and disease progression than clinical markers such as pathological complete remission. This was according to prospective study data from Belgium and Italy reported at the 2026 European Breast Cancer Conference by Elisa Agostinetto MD, a medical oncologist from the Institut Jules Bordet in Brussels.

Background:

Circulating tumor DNA (ctDNA) is a promising biomarker in early breast cancer. However, limited sample sizes in available clinical studies weaken neoadjuvant evidence.

Materials and methods: Data from two independent prospective observational studies, one at the Institut Jules Bordet (Brussels), and one at the Istituto Nazionale dei Tumori (Milan), were pooled at the individual patient level for joint analysis. In both studies, women with early breast cancer received neoadjuvant therapy and underwent primary tumor-informed ctDNA assays at predefined time points: baseline (before initiation of neoadjuvant therapy), end of neoadjuvant therapy before surgery (EoT), and during follow-up. Associations between ctDNA detection and clinico- pathological variables (age, tumor size [e.g. T ≤5 cm vs. >5 cm], hormone receptor status, HER2 status, and pathological complete response (pCR) were evaluated using χ2 or Wilcoxon tests, as appropriate. The effect of ctDNA on event-free survival (EFS) was analyzed by univariable and multivariable Cox proportional hazards models adjusted for relevant covariates. A two-sided p value< 0.05 was considered statistically significant.

Results:

A total of 81 patients were analyzed. Median age was 48 (range 27-75) years at diagnosis; most had T≤5 cm (72%), node positive (68%) and triple negative (60%) disease. Breast cancer events were 26 throughout a median follow-up of 7 years (IQR 5.3-8.8). ctDNA was detected in 31/54 (57.4%) plasma samples at baseline, and in 11/64 (17%) plasma samples at the EoT. The detection of ctDNA was significantly associated with hormone receptor-negative status both at baseline and at the EoT (p

Introduction

Patients with breast cancer undergoing mastectomy with implant-based breast reconstruction (IBBR), who are at high risk of locoregional recurrence, often require postmastectomy radiotherapy (PMRT), which increases the risk of capsular contracture (CC). The present study assessed the association between use of polyurethane coated (PUc) versus non-PUc implants and the need for surgical revision due to CC in the setting of PMRT.

Material and methods

This international multicenter retrospective real-world study included patients with breast cancer who underwent nipple- (NSM) or skin-sparing mastectomy (SSM) with prepectoral IBBR with or without PUc implants followed by PMRT. Primary endpoint was surgical revision due to CC and was analyzed using Cox regression models.

Results

1183 women treated between 2016 to 2022 at 19 sites in 13 countries (4 continents) were included. Of them, 773 (65.3%) underwent non-PUc IBBR and 410 (34.7%) PUc IBBR. Median age was 47 years (IQR 41-54) and median BMI was 24.4 kg/m2 (IQR 22-

27.6). Median follow-up was 30.8 months (IQR 18.4-45.4) in the non-PUc group and 37.4 months (IQR 30-46.2) in the PUc group (p

Background

In the Phase III trial OASIS-4 (NCT05587296), elinzanetant (EZN), a dual neurokinin (NK)-targeted therapy (NK1 and NK3 receptor antagonist), significantly reduced vasomotor symptom (VMS) frequency vs placebo (PBO) in women taking endocrine therapy (ET) for hormone receptor positive (HR+) breast cancer. This subgroup analysis evaluated EZN’s effects on VMS frequency and severity by type of ET in OASIS-4.

Materials and methods

Women aged 18–70 years experiencing ≥35 moderate-to-severe VMS/week caused by ET for HR+ breast cancer were randomized 2:1 to receive EZN 120 mg for 52 weeks or PBO for 12 weeks followed by EZN for 40 weeks. Mean changes from baseline in daily moderate-to-severe VMS frequency and severity to weeks 1 (frequency only), 4 and 12 were analyzed by ET type (tamoxifen [TAM], aromatase inhibitor [AI], ovarian function suppression [OFS; i.e., GnRH], no OFS). This post hoc analysis was not powered for statistical testing.

Results

Mean age (years) was 50.4 for TAM, 51.9 for AI, 45.2 for OFS and 53.4 for no OFS. At baseline, mean average daily moderate-to-severe VMS frequency ranged from 10.8-12.5 per day while VMS severity was 2.5 in all subgroups. Greater reductions in VMS frequency with EZN vs PBO were seen by week 1 across all subgroups (range EZN: -3.3 to -4.2; PBO: -1.6 to -2.1), with further reductions at week 4 (range EZN: -5.6 to -6.9; PBO: -2.5 to -3.7) and 12 (range EZN: -6.9 to -8.1; PBO: -3.0 to -5.8). A similar trend was observed for VMS severity at weeks 4 and 12 (Table). Reductions in VMS frequency and severity were maintained throughout the 52-week treatment period.

Conclusions

Consistent with results in the overall population, EZN had greater reductions in VMS frequency and severity than PBO with rapid onset and sustained effect over 52 weeks, irrespective of the type of ET.

Background:

Cardiac exposure during left-sided breast cancer (LBC) radiotherapy remains a key determinant of long-term morbidity and mortality. The BRAVE-HEART trial explores the clinical and dosimetric impact of Deep Inspiration Breath Hold (DIBH) using the Active Breathing Coordinator (ABC) system. This analysis quantifies the cardiac-sparing effect of ABC versus free-breathing (FB) across three fractionation schedules, validates its intrinsic benefit through intra-patient paired replanning, and assesses real-world feasibility. (ClinicalTrials.gov awaiting release)

Methods:

This ambispective single-center study included 400 patients with early or locally advanced LBC treated with 26 Gy/5 fx, 40 Gy/15 fx, or 50 Gy/25 fx ± SIB. Dosimetric parameters were extracted for the heart and LAD (Dmean, Dmax). Statistical analyses used the Shapiro–Wilk, Mann–Whitney U, and Wilcoxon tests; effect size was reported as Cohen’s d. Model-based estimation of cardiac mortality risk (NTCP) was performed for the replanning subgroup using the Gagliardi relative-seriality model. For this subgroup, paired FB and ABC-DIBH plans were generated on separate CT scans. Breath-hold performance (hold duration, threshold volume) was recorded to evaluate feasibility. The study was approved by the Ethics Committee of the Fondazione IRCCS Policlinico San Matteo, Pavia, Italy.

Results:

ABC significantly reduced cardiac and LAD exposure across all fractionations (all p < 0.001), with large effect sizes (Cohen’s d ≥0.8) indicating a strong clinical impact (Tab. 1). In intra-patient replanning, ABC confirmed its dosimetric superiority over FB (p < 0.05). Model-based NTCP for late cardiac mortality showed a halving of predicted cardiac risk with ABC (0.04 vs 0.08, p < 0.001). Breath-hold metrics confirmed high feasibility (mean DIBH ≈ 25 s; threshold ≈ 1.4 L), including in elderly patients (mean age 75 years).

Conclusions:

ABC-assisted DIBH consistently and significantly reduced cardiac and coronary exposure across all dose regimens, with high reproducibility and feasibility. Model-based NTCP and intra-patient replanning analyses demonstrate a clinically and biologically relevant reduction in predicted long-term cardiac mortality, confirming ABC-DIBH as a reliable strategy to improve cardiac safety in left-sided breast cancer radiotherapy.

Philip Poortmans MD PhD, Radiation Oncology Department, University of Antwerp & Iridium Netwerk, Belgium

BARCELONA, Spain—One of the important themes at the 2026 European Breast Cancer Conference was to individualize therapy for every patient by de-escalating some modalities of treatment in the light of the increasing efficacy of others. The Audio Journal of Oncology sought the opinion of one of Europe’s oncology leaders, Philip Poortmans MD, PhD, researcher at the Iridium Netwerk and the University of Antwerp, in Belgium about findings from the EUROPA trial looking at older patients with early breast cancer, new date on omitting radiation boost to the tumor bed after breast conserving therapy, using axillary radiotherapy in place of axillary node dissection, and the case for watchful waiting in more patients with DCIS.

Molecular Test Distinguishes Ipsilateral Second Primary from Recurrent Breast Cancer

An interview with:

Tess Snellen MD, Netherlands Cancer Institute – Antoni van Leeuwenhoek hospital, Department of Surgical Oncology, Amsterdam, The Netherlands.

BARCELONA, Spain—A molecular test using next generation sequencing has proved able to distinguish swiftly, and with great accuracy, the recurrence of a patient’s ipsilateral breast cancer from a completely new primary tumor. The 2026 European Breast Cancer Conference heard findings from researcher Tess Snellen from the Netherlands Cancer Institute in Amsterdam, who then talked with our reporter, Peter Goodwin:

Background

A second breast cancer (BC) in the ipsilateral breast or regional lymph nodes may be a true recurrence (TR) or second primary (SP) tumor. This distinction is clinically relevant, as TRs are associated with a poorer prognosis and require a more challenging therapeutic approach compared to SPs. The aim of this study was to describe the findings and success rates of molecular clonality analysis (MCA) techniques used to distinguish a second ipsilateral BC as either a TR or a SP. In addition, a comparison between a MCA-based and a clinicopathological classification was made.

Material and methods

Through electronic patient files and pathology reports, data were collected from a historical cohort of patients who underwent MCA for a second ipsilateral locoregional BC at the Netherlands Cancer Institute between 2000 and 2024. The primary objective was to describe the findings and success rates of the different MCA techniques. The secondary objective was to compare molecular with clinicopathological classification using the Jobsen Morphology method.

Results

In total, 85 patients were included, in whom 99 MCAs were performed. Before 2017, all MCA involved loss of heterozygosity (LOH) analysis (100%), hereafter, targeted next-generation sequencing (NGS) panel analysis and copy number variation (CNV) analysis were introduced. After 2017, targeted NGS panel analysis was most frequently applied (65.4%), followed by CNV (18.5%) and LOH analysis (16.0%). CNV analysis had the highest success rate (93.3%) yielding the most conclusive MCA results, followed by targeted NGS panel (73.6%), and LOH analysis (61.3%) (table 1). Of the 99 MCAs, 40.4% tumor pairs were classified as clonally related, 10.1% as likely clonally, 22.2% as not clonally related, 27.3% were inconclusive. A substantial discordance (29.6%) was observed between the MCA-based classification and Jobsen Morphology method, with clinicopathological assessment showing limited predictive value for MCA-determined TRs (PPV 78.7%, NPV 22.2%).

Conclusion

In conclusion, we demonstrate that MCA, especially targeted NGS panel and CNV analysis, is successful in distinguishing TRs from NPs. Clinicopathological classification using the Jobsen Morphology method however has limited value in predicting clonal relatedness. Therefore, we recommend implementing MCA in the diagnostic workup of second ipsilateral BC when the outcome may influence therapeutic decision-making, as part of a tailored treatment approach for BC recurrence.

Abstract

Background

Pts with HER2+ early BC with residual invasive disease after neoadjuvant tx are at high risk of recurrence highlighting a significant unmet need. We present interim analysis results of DESTINY-Breast05 (NCT04622319), an open-label, phase 3 trial of post-neoadjuvant T-DXd vs standard of care (SOC) T-DM1 in HER2+ early BC.

Methods

Pts with residual invasive HER2+ BC after neoadjuvant tx consisting of taxane-based chemotherapy and anti-HER2 tx and at high risk for recurrence* were randomized 1:1 to T-DXd 5.4 mg/kg or T-DM1 3.6 mg/kg once every 3 weeks for 14 cycles. Primary endpoint was IDFS. Key secondary endpoint was DFS; others were overall survival, distant recurrence-free interval, brain metastasis–free interval (BMFI), and safety.

Results

At data cutoff (July 2, 2025), 1635 pts were randomized to T-DXd (n = 818) or T-DM1 (n = 817). Median study duration was 29.9 months with T-DXd and 29.7 months with T-DM1. IDFS and DFS benefit with T-DXd vs T-DM1 was statistically significant (HR, 0.47 each; Table); BMFI improvement with T-DXd was clinically meaningful (HR, 0.64; 95% CI, 0.35-1.17). Grade ≥3 treatment-emergent adverse events (TEAEs) occurred in 50.6% of pts with T-DXd and 51.9% of pts with T-DM1; adjudicated drug-related interstitial lung disease occurred in 9.6% (n = 2 grade 5) and 1.6% of pts (0 grade 5) and were mostly grade 1 or 2. TEAEs associated with death occurred in 0.4% (n = 3) and 0.6% (n = 5) of pts, respectively. Table: LBA1

Background

The first-line standard of care (SOC) for patients (pts) with estrogen receptor-positive, HER2-negative advanced breast cancer (ER+, HER2- aBC) is CDK4/6 inhibitor (i) + endocrine therapy (ET) but effective post-CDK4/6i options remain limited. Giredestrant (GIRE) targets the ER pathway while everolimus (E) targets the PI3K/AKT/mTOR pathway; both of which are implicated in driving resistance in the post-CDK4/6i setting. evERA BC (NCT05306340) is the first Phase III trial to demonstrate statistically significant and clinically meaningful improvement in investigator-assessed progression-free survival (INV-PFS) with an all-oral selective ER antagonist and degrader combination of GIRE + E vs SOC ET + E in pts with ER+, HER2- aBC post-CDK4/6i + ET, both in pts whose tumors had a detectable ESR1 mutation (m) and in the intent-to-treat (ITT) population (Mayer ESMO 2025). The safety profile of GIRE + E was manageable with no unexpected findings (Mayer ESMO 2025). We report results from prespecified exploratory subgroup analyses.

Methods

Pts who had ER+, HER2- aBC with disease progression (PD) post-CDK4/6i + ET in the aBC setting, or relapse during/after CDK4/6i + ET in the adjuvant setting, were randomized 1:1 to once-daily oral 30 mg GIRE + 10 mg E or SOC ET (exemestane, fulvestrant, or tamoxifen) + E until PD or unacceptable toxicity. Mutational status was determined using circulating tumor DNA at baseline. The co-primary endpoints were INV-PFS per Response Evaluation Criteria in Solid Tumors v1.1 in pts whose tumors had detectable ESR1m and in the ITT population. INV-PFS was assessed by subgroup analyses.

Results

Three-hundred-and-seventy-three pts were randomized; 183 pts were randomized to GIRE + E and 190 to SOC ET + E. A total of 207 pts (55%) had tumors with ESR1m, 115 (31%) had PIK3CAm, and 137 (37%) had alterations (alt) in the PI3K pathway genes (PIK3CA/AKT1/PTEN). Sixty-four pts (17%) had both ESR1m and PIK3CAm; 76 (20%) had both ESR1m and PIK3CA/AKT1/PTEN alt. Ninety-eight percent of pts received a CDK4/6i in the metastatic setting. INV-PFS benefit was observed for GIRE + E vs SOC ET + E regardless of PIK3CAm status or PIK3CA/AKT1/PTEN alt in both the ESR1m and ITT populations (Table). Consistent benefit was observed regardless of duration of prior CDK4/6i (Table). Data for additional subgroup analyses for prior therapy will be presented.

Conclusions

GIRE + E led to clinically meaningful improvements in INV-PFS vs SOC ET + E irrespective of PIK3CAm and PIK3CA/AKT1/PTEN alt, and other key relevant subgroups, regardless of ESR1m status. These data support the use of GIRE + E vs SOC ET + E in pts with ER+, HER2- aBC post-CDK4/6i + ET.

Introduction

Current treatment for chronic lymphocytic leukemia (CLL) follows two seminal paradigms: continuous Bruton tyrosine kinase inhibitor (BTKi) therapy until progression and fixed-duration regimens combining BCL2 inhibitors with a CD20 antibody or BTKi, typically given over one year. These two different approaches were established through comparisons to chemo(immuno)therapy and are yet to be compared directly. Here we present data of a prospective trial comparing continuous ibrutinib (I) monotherapy to fixed-duration venetoclax plus obinutuzumab (VO) and venetoclax plus ibrutinib (VI) for CLL.

Methods

CLL17 (NCT04608318) is an investigator-initiated, international, randomized phase 3 trial for patients (pts) with previously untreated CLL. Pts were randomized to receive ibrutinib (I), fixed-duration venetoclax plus obinutuzumab (VO) or fixed-duration venetoclax plus ibrutinib (VI). Randomization was stratified by IGHV status, del(17p)/TP53mut and patient fitness, defined by cumulative illness rating scale (CIRS) score >6 and/or creatinine clearance

ASTRACT:

Background

GC012F/AZD0120 is an autologous CAR-T therapy that targets both B cell maturation antigen (BCMA) and CD19. It is developed using the novel FasTCAR-T platform, which allows for next-day manufacturing. GC012F/AZD0120 has demonstrated deep and durable responses with a manageable safety profile in relapsed/refractory multiple myeloma (RRMM) patients (pts). We conducted two phase 1, open-label, investigator-initiated trials (NCT04935580, NCT05840107) to evaluate safety and efficacy of GC012F/AZD0120 in newly diagnosed multiple myeloma (NDMM) pts, including transplant eligible high risk (TE HR) NDMM and transplant ineligible (TI) NDMM. Here, we report the combined data of these two studies to provide long term follow up data of GC012F/AZD0120 in NDMM pts.

Methods

Eligible NDMM pts received a single infusion of GC012F/AZD0120 following two cycles lenalidomide, bortezomib and dexamethasone (RVd) induction therapy. Leukapheresis was performed before induction therapy, or after 1 or 2 cycles of induction therapy. GC012F/AZD0120 was administered at 4 dose levels: 1×105/kg (n=1), 1.5×105/kg (n=3), 2×105/kg (n=4), or 3×105/kg (n=22) after a standard 3-day lymphodepletion regimen of fludarabine and cyclophosphamide. Lenalidomide maintenance was permitted to be administered post infusion per investigator’s discretion.

Results

As of June 3, 2025, a total of 30 patients were infused and evaluable. The median age was 64 years (range, 43-78), with 27% aged over 70 years. 19 pts (63%) were male. 25 pts (83%) had R-ISS stage II/III and 14 of 29 pts (48%) had high risk cytogenetics (dep (17p), amp (1q21), t (4;14), t (14;16)). 17 pts (57%) had plasmacytomas, and 3 of them had soft tissue plasmacytomas. 29 pts (97%) received 2 cycles of RVd induction therapy prior to CAR-T infusion. The overall response rate (ORR) was 100%, and the stringent complete response (sCR) rate was 97%. The median time to first response was 28 days and the median time to best response was 68 days. All treated pts (100%) across all dose levels achieved minimal residual disease (MRD) negativity, as assessed by Euroflow (sensitivity of 10-6). Among MRD evaluable pts, MRD negativity reached 100%, 93% and 92% at Month 1, Month 6 and Month 12, respectively. 81.5% (22/27) pts’ MRD negativity sustained more than 12 months. With a median follow-up of 30 months (range, 13-47), the median progression-free survival (PFS) and overall response (OS) have not been reached. The 30-month PFS rate was 88% (95% CI 67–96) and 30-month OS rate was 92% (95% CI 71–98). For 3 soft tissue plasmacytomas pts, the median PFS was 17.9 months and the median OS was 20.8 months, significantly shorter than bone related plasmacytomas and non-plasmacytomas pts. No difference was observed between pts with high risk and non-high-risk cytogenetics. GC012F/AZD0120 was well tolerated. Cytokine release syndrome (CRS) occurred in 10 pts (33%), all grade 1–2 (grade 1, n=9; grade 2, n=1); no grade ≥3 CRS was observed. The median time to onset was 8 (range, 6-18), with a median duration of 2 days (range, 1-8). 3 pts were treated with one dose of tocilizumab and 1 pt was treated with one dose of tocilizumab and corticosteroids. No patient developed ICANS of any grade. Robust CAR T-cell expansion was observed in all pts, with a median peak expansion (Cmax) of 62,644 copies /μg DNA and a median Tmax of 10 days. The median Tlast was 29 days. sBCMA level declined sharply post infusion, reaching to nadir with a median time of 2 months. 23 pts (77%) received lenalidomide as maintenance treatment, with a median initiation time of 6 months post infusion.

Conclusion

Consistent with findings from the previous relapsed/ refractory MM cohort treated with GC012F/AZD0120, data from these two studies demonstrates that GC012F/AZD0120 induced deep and durable responses in NDMM pts, with a highly favorable safety profile. All patients responded (100% ORR) and all four dose groups achieved MRD negativity. These promising results highlight the potential of GC012F/AZD0120 CAR-T therapy for treating NDMM patients with HR features and transplant ineligible NDMM pts. Further research with a larger patient population and extended follow-up is needed to validate these findings and address this critically unmet medical need.

SAN ANTONIO, USA— Breast cancers that convert from clinically node-positive to node-negative as a result of neoadjuvant chemotherapy, do not need axillary lymph node dissection, regardless of tumor type.

Less invasive axillary surgical staging procedures (such as sentinel node dissection and targeted axillary dissection) were just as good in terms of three-year outcomes, regardless of initial tumor stage or subtype, in findings from the international, prospective, multicenter AXSANA/EUBREAST 3 (R) study reported at the 2025 San Antonio Breast Cancer symposium by Thorsten Kühn MD PhD, Head of the Breast Center at the Filderklinik near Stuttgart, Germany, Senior Consultant, at the University of Ulm and Chairman of the European Breast Cancer Research Association of Surgical Trialists. At the symposium he gave more details to Audio Journal of Oncology reporter, Peter Goodwin:

TITLE:

“More versus less invasive axillary surgical staging procedures in breast cancer patients converting from a clinically node-positive to a clinically node-negative stage through neoadjuvant chemotherapy – primary endpoint analysis of the international prospective multicenter AXSANA/EUBREAST 3(R)study“

AUTHOR:

Introduction:

In breast cancer patients converting from clinically positive (cN+) to negative (ycN0) lymph node status after neoadjuvant chemotherapy (NACT), surgical staging by axillary lymph node dissection (ALND) is increasingly replaced by less invasive procedures like targeted axillary dissection (TAD) or sentinel lymph node biopsy (SLNB), possibly followed by completion ALND or regional radiotherapy if positive. Prospective data comparing oncologic safety of different procedures as a primary approach after NACT are currently scarce. We report 3-year axillary recurrence-free survival (ARFS) as the first primary endpoint analysis of the AXSANA/EUBREAST 3(R) study (NCT04373655, www.eubreast.org/axsana), initiated by the European Breast Cancer Research Association of Surgical Trialists (EUBREAST e.V.).

Methods

In an international multicenter cohort study, patients with cN+ breast cancer who receive at least four cycles of NACT and convert to ycN0 are eligible. Axillary staging after NACT is performed according to institutional routine. Grouping of patients was based on the primary staging procedure, not on final axillary surgery, e.g., completion ALND following a positive SLNB was classified as SLNB. Co-primary endpoints are ARFS, invasive breast cancer-specific survival (iBCSS), and patient-reported quality of life. Data entry is systematically monitored. Less extensive axillary staging procedures as first surgery after NACT (TAD, SLNB, targeted lymph node biopsy (TLNB)) are considered non-inferior to staging by ALND if the lower bound of a two-sided 90% confidence interval (CI) around 3-year ARFS exceeds 97%. 750 patients were required per group (TAD/SLNB/TLNB vs ALND).

Results

From June 2020 to April 2025, 6,474 patients (26 countries, 288 study sites) were enrolled, 2,632 of whom had completed surgery by December 31, 2023 and were selected for analysis. Primary staging procedure was ALND in 799 patients (30.4%) and less invasive procedures (419 SLNB, 1399 TAD, 15 TLNB) in 1,833 (69.6%). Nodal complete pathological response was reported in 1,345 patients (51.1%): 423 (31.4%) after ALND and 922 (68.6%) after TAD/SLNB/TLNB. 2489 patients (94.6%) received post-NACT nodal radiotherapy: 759 (95.0%) after ALND and 1730 (94.4%) after TAD/SLNB/TLNB.

After a median follow-up of 2.0 years (range, 0.01-4.5), 15 axillary recurrences occurred after TAD/SLNB/TLNB and 4 after ALND (4.2 vs 2.5 events/1000 person-years, p=0.351). 3-year ARFS was 99.2% (95% CI 98.2-100.0) after ALND and 98.8% (95% CI 98.1-99.5) after TAD/SLNB/TLNB. For TAD/SLNB/TLNB, the lower bound of a 90% CI was 98.2%. After SLNB, 1 axillary recurrence occurred and 14 after TAD (1.2 vs 5.1 events/1000 person-years, p=0.132). Results

were similar upon controlling for clinicopathological risk factors and neoadjuvant treatment or exclusion of 143 patients without radiotherapy. iBCSS at 3 years was 85.7% (95% CI 82.6-89.0) for ALND and 88.2% (95% CI 86.0-90.3) for TAD/SLNB/TLNB.

Conclusion

In patients who convert from clinically node-positive to node-negative breast cancer, the AXSANA study showed that less invasive surgical staging procedures are associated with a low axillary recurrence rate, not inferior to ALND after 3 years, regardless of initial tumor stage or subtype. These findings reinforce efforts to minimize surgical morbidity without compromising oncologic outcomes.

ABSTRACT:

Introduction: In RRMM, increasing rates of pt attrition and decreasing durability of responses with each line of therapy (LOT) necessitate early treatment (tx) with the most effective therapies. Immunotherapies that are widely accessible across different MM tx settings have the potential to change the trajectory of RRMM.

Teclistamab (Tec), the first approved BCMA×CD3 bispecific antibody (BsAb) for heavily pretreated RRMM, provided deep, durable responses in MajesTEC-1, with improved efficacy and safety in earlier LOTs. Daratumumab (Dara), a standard-of-care (SoC) foundational CD38 targeted therapy with direct on-tumor activity, has been shown to deplete immunosuppressive T-cells and expand cytotoxic T-cells, creating an immune-permissive microenvironment for synergistic Tec-mediated killing of MM cells. MajesTEC-3 (NCT05083169) evaluates Tec-Dara vs SoC DPd/DVd in RRMM. We report initial results for this first phase 3 study of BsAb therapy in MM.

Methods: Eligible pts had 1-3 prior LOTs including a PI and lenalidomide (Len; pts with 1 prior LOT must have been Len-refractory) with progressive disease (PD) on or after the last LOT. Pts with prior BCMA-directed therapy or refractory to anti-CD38 were excluded; prior anti-CD38 exposure was permitted. Pts were randomized 1:1 to Tec-Dara or DPd/DVd. The Tec-Dara group received 28-day cycles (C) of Tec (1.5 mg/kg QW in C1-2 [C1 preceded by the approved step-up dose schedule]; 3 mg/kg Q2W in C3-6; and 3 mg/kg Q4W in C7+) with Dara; steroids were not required after C1 Day 8. Tec and Dara dosing were aligned with the approved Dara schedule. DPd/DVd were administered per approved schedules. Progression-free survival (PFS) by IRC was the primary endpoint; secondary endpoints included complete response or better (≥CR), overall response, minimal residual disease (MRD) negativity (10–5; next-generation sequencing), overall survival (OS), time to worsening of symptoms (MySIm-Q), and safety.

Results: 587 pts were randomized (Tec-Dara, n=291; DPd/DVd, n=296). Median (range) age was 64 (25-88) yrs, median number of prior LOTs was 2 (1-3). With 34.5-mo median follow-up, Tec-Dara significantly improved PFS vs DPd/DVd (HR, 0.17; 95% CI, 0.12-0.23; P

ABSTRACT:

Purpose:

The HER2CLIMB-05 study (ClinicalTrials.gov identifier: NCT05132582) is investigating the efficacy and safety of adding tucatinib to trastuzumab and pertuzumab as first-line (1L) maintenance therapy in patients with human epidermal growth factor receptor 2-positive (HER2+) metastatic breast cancer (MBC).

Methods:

Patients with centrally confirmed HER2+ MBC without evidence of progression post induction therapy and no or asymptomatic brain metastases (BM) were enrolled. Patients were randomly assigned 1:1 to tucatinib (300 mg) or placebo twice a day combined with trastuzumab/pertuzumab. The primary end point is investigator-assessed progression-free survival (PFS); secondary end points include overall survival (OS), PFS per blinded independent central review, CNS-PFS, and safety.

Results:

Between March 2022 and July 2024, 654 patients were randomly assigned to tucatinib (n = 326) and placebo (n = 328) arms. All patients were female (median age, 54 years), 69.3% had de novo MBC, 52.6% were hormone receptor-positive, and 12.4% had presence/history of baseline BM. In this primary analysis, PFS was statistically significantly improved with addition of tucatinib versus placebo (hazard ratio, 0.641 [95% CI, 0.514 to 0.799]; P < .0001; median PFS: 24.9 v 16.3 months); a PFS benefit was seen regardless of the presence/absence of BM or hormone receptor status. OS data remain immature. The most common treatment-emergent adverse events (TEAEs) in the tucatinib arm were diarrhea (72.7%), nausea (33.1%), and elevated liver enzymes (ALT: 28.2%; AST: 25.8%), of which 6.1%, 0.9%, 13.5%, and 7.1%, respectively, were grade ≥3. In the tucatinib arm, 13.5% discontinued tucatinib because of TEAEs.

Conclusion:

Tucatinib addition to trastuzumab and pertuzumab demonstrated improvement in PFS with no new safety signals identified and may be an option for 1L maintenance therapy in patients with HER2+ MBC.

Abstract

Introduction: Pirtobrutinib is a highly selective, non-covalent (nc) Bruton tyrosine kinase inhibitor (BTKi) that has demonstrated safety and efficacy in patients (pts) with relapsed/refractory (R/R) chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), including pts previously treated with a cBTKi. While cBTKi have significantly improved progression-free survival (PFS) for untreated pts with CLL/SLL, there are no Phase 3 data assessing a ncBTKi specifically in the treatment-naïve setting, and significant improvements in overall survival (OS) are uncommon with monotherapy cBTKi. A recent head-to-head phase 3 trial (BRUIN CLL-314 presented at this meeting, ASH abstract 25-2587; NCT05254743) showed a favorable overall response rate (ORR) and a positive PFS trend with pirtobrutinib compared to the cBTKi ibrutinib in a subset of pts with treatment-naïve CLL. Here we present the first results from a randomized, open-label, global phase 3 trial specifically assessing the efficacy and safety of pirtobrutinib versus bendamustine plus rituximab (BR) in treatment-naïve pts with CLL/SLL (BRUIN CLL-313; NCT05023980).

Methods: Pts with previously untreated CLL/SLL, without del(17p), were randomized 1:1 to receive pirtobrutinib monotherapy (200 mg QD) or 6 cycles of BR, stratified by IGHV mutation status (mutated vs unmutated) and Rai stage (low/intermediate vs high). Pts with known CLL/SLL CNS involvement, Richter transformation, or significant cardiovascular disease were excluded. Responses were evaluated using iwCLL 2018 criteria. The primary endpoint was PFS assessed by independent review committee (IRC), and a stratified log-rank test compared IRC-assessed PFS between pirtobrutinib and BR using a 2-sided alpha level of 0.05. OS was a key secondary endpoint, gated on IRC-assessed PFS, with a small alpha of 0.000001 spent at this interim OS analysis. Other secondary endpoints included investigator (INV)-assessed PFS and safety. Efficacy analyses were based on the intent-to-treat population. Pts assigned to BR were eligible to cross over to receive pirtobrutinib if they had IRC-confirmed disease progression (PD), met study eligibility requirements, and needed therapy per iwCLL criteria. The data cutoff was 11 July 2025.

Results: 282 pts were randomized to receive either pirtobrutinib (n=141) or BR (n=141). At a median follow-up of 28.1 months, the primary endpoint of IRC-assessed PFS was significantly improved with pirtobrutinib compared with BR (HR: 0.199; 95% CI: 0.107, 0.367; p

An interview with:

Gaorav Gupta MD PhD, Associate Professor Radiation Oncology, University of North Carolina at Chapel Hill, North Carolina, USA

SAN ANTONIO, USA—Patients with the most common form of breast cancer could respond better to immunotherapy and chemotherapy if they received neo-adjuvant radiation therapy. This is the implication of findings from the TBCRC-053 (P-RAD) study in patients with hormone receptor-positive, HER2-negative breast cancer which found an increase of T-cell infiltration among patients who had pre-operative radiation compared with those who did not.

The study findings were reported at the 2025 San Antonio Breast Cancer Symposium by Garav Gupta, MD PhD, an Associate Professor at the University of North Carolina at Chapel Hill, USA. After his talk at the conference he met up with the Audio Journal of Oncology’s Peter Goodwin:

Abstract

Introduction: Hormone receptor positive (HR+), HER2- breast cancer (BC) is the most common subtype of BC. Despite advances in chemotherapy and endocrine therapy optimization, local and systemic recurrences frequently occur, especially for patients with node-positive disease. Recent data suggest a subset of patients with this tumor phenotype may benefit from the addition of anti-Programmed Death-1(aPD1) to neoadjuvant chemotherapy. However, T-cell infiltration (TCI), a biomarker of response to a PD1 and chemotherapy, is typically low in this BC subtype. Preclinical models show that combining preoperative radiation therapy (preop RT) with immune checkpoint inhibitors can enhance TCI and anti-tumor immunity. We conducted the first randomized trial to test whether no-, low- or high-dose RT combined with aPD1 increases TCI and improves responses in non-irradiated, metastatic lymph nodes in HR+/HER2- BC (NCT04443348).

Materials & Methods: Eligible patients had ER and/or PR≥10%, HER2 negative invasive BC with clipped and biopsy-proven positive axillary node(s), cT1c-T4c, cN1-3, and at least one of the following criteria: grade 3 or grade 1-2 with cN2-N3, Ki67 >20%, or high genomic assay score. Between 2022-2024, 51 patients from 10 centers were randomized to no (0Gy; control arm), low (9Gy) or high (24Gy) doses of preop RT to the primary tumor with concurrent pembrolizumab followed by a 2-week tumor biopsy. Stratification factors were T1c vs. T2-4 and N1 vs. N2-3. Patients subsequently received pembrolizumab with 12 weeks of paclitaxel, followed by 4 cycles of adriamycin-cyclophosphamide (q2wk or q3wk) with pembrolizumab (200 mg q3 wks or 400 mg q6 wks). Surgery and adjuvant therapy followed standard-of-care. Dual co-primary endpoints were 2wk tumor TCI and nodal pathologic complete response (ypN0) at time of definitive surgery. TCI was assessed by multiplex immunofluorescence (pan-cytokeratin, CD3, CD8), using a rank-based Immunoscore (range 0-1), compared to baseline reference biopsies via two-tailed Mann-Whitney test. ypN0 was evaluated non-comparatively. Secondary endpoints included pCR and Residual Cancer Burden (RCB) 0/1.

Results: Among 51 patients enrolled, 49 were evaluable for TCI and 48 for the ypN0 endpoint. Median age was 49.5 years (range 23-78). The cohort had a high-risk clinical profile: 92% had cT2-4, 50% N2-3, and 62% grade 3 tumors. Median ER and PR positivity were 90% (20-100) and 68% (1-98), respectively. Multifocal or multicentric tumors were present in 32%. TCI was assessed at 2 weeks post-treatment. The proportion of tumors with TCI in the upper quartile increased with RT dose escalation: 31% (0Gy), 40% (9Gy), and 53% (24Gy). Median TCI scores at 2 weeks were 0.60 (0Gy), 0.56 (9Gy), and 0.82 (24Gy), compared to a median baseline value of 0.50 from untreated reference samples. A statistically significant increase in TCI was observed only in the 24Gy cohort relative to the untreated group (p=0.027). 70.8% underwent mastectomy, with 39.6% receiving immediate reconstruction. 8% experienced G2/3 wound complications, balanced across arms. Median number of lymph nodes removed was 6.5 (1-42). The overall ypN0 rate was 29%, and 24%(0Gy), 29%(9Gy) and 33%(24Gy) per arm. pCR/RCB 0-1 rates were 18%/27% in the entire cohort and 6%/18%(0Gy), 29%/29%(9Gy), and 19%/33%(24Gy), respectively.

Conclusion: The addition of 24Gy preop RT to a PD1 significantly increased tumor TCI in HR+/HER2- early-stage BC. Non-irradiated nodal response rates were promising despite over one-third of the study population with grade 1/2 tumors and high disease burden, laying the foundation for a future randomized trial comparing the efficacy of this novel approach against standard of care for node-positive HR+/HER2- BC.

Bispecific Antibody Epcoritamab Combination Beats Standard of Care for Patients with Relapsed/Refractory Follicular Lymphoma

An interview with:

Lorenzo Falchi MD, Lymphoma Service, Attending Physician, Memorial Sloan Kettering Cancer Center, New York NY, USA

ORLANDO, USA—A bispecific antibody to treat follicular lymphoma has outperformed standard rituximab plus lenalidomide in patients whose disease has relapsed or who are refractory to standard first-line treatments. This was in the phase three epcore FL-1 trial in which patients receiving rituximab and lenalidomide were randomly assigned to have the CD3xCD20 bispecific Epcoritamab or a placebo added to their therapy.

At the 2025 Annual Meeting of the American Society of Hematology the findings were reported by Lorenzo Falchi MD, Lymphoma Service, Attending Physician, Memorial Sloan Kettering Cancer Center, New York NY, USA, who afterwards spoke with the Audio Journal of Oncology’s Peter Goodwin:

INTRODUCTION:

Patients (pts) with relapsed/refractory (R/R) follicular lymphoma FL have limited second line (2L) treatment options, rituximab and lenalidomideR2being the only 2L alternative to immunochemotherapy-based therapy. Epcoritamab (epcor), a CD3xCD20 bispecific antibody, is approved for R/R FL as monotherapy after ≥2 lines of systemic therapy. Epcor plus R2 (E+R2) is a chemotherapy-free regimen which showed promising antitumor activity (97% overall response rate [ORR], 87% complete response [CR] rate) and manageable safety in the phase 1b/2 EPCORE NHL-2 trial (Falchi et al, ASH 2024). We report the results of EPCORE FL-1: the first global phase 3 trial of fixed-duration bispecific antibody regimen E+R2 vs R2 in pts with 2L+ FL (NCT05409066).

METHODS:

Adults with CD20+ FL R/R after at least 1 prior line, who met GELF criteria, were randomized to receive E+R2or R2for up to 12 cycles (C). Subcutaneous epcor was administered using a 2-step-up dose (2SUD) or 3-step-up dose (3SUD) regimen and full doses (48mg) thereafter. Epcor was administered weekly in C1–3 and q28 days from C4–12. Intravenous rituximab was administered weekly in C1 and q28 days during C2–5. Oral lenalidomide was administered daily from day 1–21 during C1–12. Pts received mandatory CRS prophylaxis in C1. Dual primary endpoints were ORR and progression-free survival (PFS) assessed by independent review committee per Lugano criteria. Secondary endpoints included CR rate (CRR), overall survival (OS), duration of response/CR (DOR/DOCR), and safety.

RESULTS:

As of the Jan 10, 2025 data cut-off, 488 pts were randomized to receive E+R2 (N=243) or R2alone (N=245). Pt characteristics were generally well balanced across the two arms. Pts treated with E+R2 vs R2had a median age of 60 years (range, 30–84) vs 63 years (range, 24–89), Ann Arbor stage III-IV in 84.8% vs 81.6%, double refractory disease in 35.4% vs 35.9%, and POD24 in 43% vs 36%, respectively. The median number of prior lines of treatment was 1 (range, 1–7) vs 1 (range, 1–6), respectively. The median duration of follow-up was 10.4 months (95% CI: 9.8, 11.1). A preplanned interim analysis was conducted after the first 232 pts achieved 12 months of follow-up post-randomization, and the ORR was significantly improved in pts treated with E+R2 (95.7% [95% CI: 90.2, 98.6]) vs R2(81.0% [95% CI: 72.7, 87.7]; P

SAN ANTONIO, USA—Post-menopausal women treated with denosumab to give bone protection along with their aromatase inhibitor hormone therapy did better if their tumors tested positive for the progesterone receptor as well as for the estrogen receptor. This is according to finding from the ABCSG 18 Study (of the Austrian Breast and Colorectal Cancer Study Group).

The research was reported at the 2025 San Antonio Breast Cancer Symposium by Christian Singer MD, Professor of Clinical-Translational Gynecological Oncology at the Medical University of Vienna, Austria. The Audio Journal of Oncology’s Peter Goodwin called to see him at his poster to find out more:

Title:

The improved long-term outcome in denosumab-treated postmenopausal women with early luminal breast cancer in ABCSG 18 is driven by progesterone receptor (PR)-positive tumors.

Background:

The biological effects of progesterone are mediated through the RANK/RANK-ligand system, which promotes tumor growth and malignant behavior in breast cancer models. In the large prospective, double-blind, placebo-controlled, phase 3 ABCSG 18 trial we have demonstrated that the addition of the RANK ligand denosumab dramatically reduces fractures compared to placebo, but also improves disease-free survival (DFS), and overall survival (OS) in aromatase inhibitor-treated postmenopausal patients with early luminal breast cancer.

Patients and Methods:

Tumor histological grade, as well as immunohistochemically quantified Ki-67, estrogen receptor (ER), and progesterone receptor (PR) data were collected from 2,026 patients. ER and PR were assessed according to the Allred score and considered positive if ≥3. Disease-free survival (DFS), distant recurrence-free (DRFS), and overall survival (OS) data were prospectively collected during a median follow-up (FU) of 8.1 years as part of the ABCSG 18 study. Cox Models were used to evaluate the association with outcome.

Results:

Overall, luminal A-like tumors had a better DFS, DRFS, and OS than luminal B-like tumors, but PR expression per se was not prognostic in this large prospective clinical trial. Patients with PR positive tumors, however, who were treated with denosumab, enjoyed a considerably better long-term outcome than patients who had been randomized to the placebo arm (HR for DFS: 0.80; 95% CI 0.65-0.98; HR for DRFS: 0.68; 95% CI 0.51-0.90; HR for OS 0.63; 95% CI 0.46-0.88). In contrast, in patients with PR-negative tumors, no differences in long-term outcomes between the denosumab or placebo arm of the trial were observed (HR for DFS: 0.87; 95% CI 0.46-1.64; HR for DRFS: 1.19; 95% CI 0.53-2.66; HR for OS 0.99; 95% CI 0.37-2.65). While the HR for DFS in denosumab vs placebo patients remained stable with increasing Allred scores, HRs for DRFS and OS improved with increasing Allred scores, thereby suggesting that the efficacy of denosumab depends on the degree of intra-tumoral PR expression.

Conclusion:

Our results indicate that the long-term outcome benefit for adjuvant denosumab in this large prospective randomized placebo-controlled trial is driven by patients with PR-positive tumors. The disruption of PR signaling, either via PR antagonization or by RANKL inhibition, could therefore be a promising therapeutic strategy in luminal breast cancer.

Introduction:

For decades, standard upfront treatment for acute myeloid leukemia (AML) among fit patients (pts) has been intensive induction chemotherapy (IC), typically with cytarabine and anthracyclines. However, long-term outcomes remain poor, and IC continues to pose substantial short- and long-term morbidities, with significant burden to pts and hospitals. VIALE-A, a phase 3 trial of IC-ineligible pts, established superiority of azacitidine and venetoclax (aza-ven) vs aza alone, with a median OS of 15 months and composite remission rate (CCR) of 66%, which compare favorably to that expected for IC among older pts. We prospectively tested whether aza-ven was superior to IC in fit pts and could challenge the current treatment standard.

Methods:

This open-label, multicenter, phase II randomized clinical trial compared the therapeutic activity of conventional IC (7+3 regimen or liposomal daunorubicin and cytarabine [CPX351]) to aza-ven among IC-eligible pts aged ≥ 18. Pts with core binding factor fusions, FLT3 mutations, or NPM1 mutations (unless aged ≥ 60) were excluded. The IC arm incorporated cycles of chemotherapy consolidation following induction, for use as clinically appropriate per current standard of care. Pts were allowed to proceed to transplant (HCT) on both arms following response on protocol-directed therapy.

The primary endpoint was event free survival (EFS), with events defined as progressive disease, persistent disease prompting therapy change, relapse, hospice, or death. Among secondary endpoints were response rates, OS, toxicity, measurable residual disease (MRD), hospitalization metrics, and quality of life (QOL). Pts were stratified by age (≥ 65 vs < 65) and pre-randomization selection in the IC arm to 7+3 or CPX351. EFS is estimated by Kaplan Meier method and assessed by log rank test and Cox PH regression. Clinical responses are assessed using an exact binomial test. Significance is declared at the two-sided 0.1 type I error.

Results:

As of 7/25/2025, 172 pts at 9 US centers were randomized to aza-ven (n=86) or IC (n=86), and accrual is complete. Median age was 64 for aza-ven and 65 for IC pts. 55% and 60% were male in the aza-ven and IC arms, respectively, and 65% and 69% were White. The majority of pts were ELN 2022 adverse risk (72%), 15% were intermediate-, and 12% favorable-risk. Distribution of risk categories did not differ across arms (p=0.44), nor did the proportions of TP53, NPM1, or IDH1/2 mutations. Median number of cycles completed were 4 for aza-ven and 2 for IC pts. Among IC pts, 54% received 7+3, and the rest, CPX351.

By intent to treat analysis, the rate of overall response (OR=CR+CRh+CRi+PR+MLFS) was significantly higher in the aza-ven arm (88% vs 62%; P

Abstract:

Introduction: Covalent Bruton tyrosine kinase inhibitors (cBTKi) are a mainstay of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) treatment. Pirtobrutinib is a highly selective, non-covalent BTKi with proven efficacy in CLL/SLL patients (pts) previously treated with a cBTKi. We report results from the first head-to-head comparison of pirtobrutinib versus ibrutinib in treatment-naïve (TN) pts and pts with cBTKi-naive relapsed/refractory (R/R) CLL/SLL (NCT05254743).

Methods:

Eligible pts were randomized 1:1 to receive pirtobrutinib (200 mg QD) or ibrutinib (420 mg QD), stratified by del(17p) status and number of prior lines of therapy (0 vs 1 vs ≥ 2). Treatment was administered until progression or development of unacceptable toxicity. Primary endpoints were non-inferiority (NI) of overall response rate (ORR; partial response or better by independent review committee [IRC]/iwCLL 2018), in intent-to-treat (ITT) and R/R populations, with ORR ratio NI margins of 0.88 and 0.86, respectively. PFS was a secondary endpoint to be tested for superiority at a future timepoint. We present the final ORR analyses in ITT and R/R populations, and descriptive analyses of secondary endpoints, including in the TN population, using a 10June2025 data cut.

Results:

From 18August2022 to 17June2024, 662 pts were randomized to receive pirtobrutinib (n=331) or ibrutinib (n=331). For both arms, the median age was 67 (pirtobrutinib range, 39-90; ibrutinib, 34-86), and the median number of prior therapies was 1. The ITT population included 225 TN and 437 R/R pts. Among pirtobrutinib vs ibrutinib pts with evaluable samples, unmutated IGHV was 68% (199/293) vs 66% (183/277), complex karyotype ≥3 abnormalities was 40% (104/259) vs 34% (78/227), and del(17p) was 15% (50/331) vs 16% (52/331), respectively. The study met its primary endpoint demonstrating statistically significant NI of ORR of pirtobrutinib vs ibrutinib in both the ITT population (87.0% [95%CI,82.9-90.4] vs 78.6% [95%CI,73.7-82.9]; ORR ratio=1.11 [95%CI,1.03-1.19]; 2-sided p

Background:

The gut microbiome has been shown to influence response to immune checkpoint inhibitors (ICI). This study aimed to investigate the association between gut microbiome profiles and clinical outcomes in patients with early-stage HER2-positive (HER2+) breast cancer receiving neoadjuvant HER2-targeted therapy +/- immunotherapy with pembrolizumab (K) as part of the randomized phase II neoHIP trial. Methods: Patients with stage II-III HER2+ breast cancer were randomized to 3 treatment arms: Arm A consisted of paclitaxel (T), trastuzumab (H), and pertuzumab (P), THP; Arm B of THP-K; and Arm C of TH-K. Fecal samples were collected at baseline, cycle 3 day 1, surgery, and at 30 and 60 days post-surgery and were analyzed using deep shotgun metagenomics sequencing. Pre-operative fecal samples were analyzed according to pathologic complete response (pCR) and onset of diarrhea during the neoadjuvant period. Comparisons were adjusted to control for false discovery rates (q-value).

Results:

99 fecal samples (Arm A: n=32; Arm B: n=48; Arm C: n=19) from 27 patients were included in the analysis. Bacterial diversity by Jaccard analysis was significantly different across all time points for all arms (all p

Phase 1b LINKER-MM2 trial (NCT05137054).

Introduction

LINVO, a human B-cell maturation antigen (BCMA)xCD3 bispecific antibody, was recently approved for triple-class exposed (TCE) RRMM after ≥3 prior therapies (EU) or ≥4 prior lines of therapy (US), demonstrating high efficacy and a generally manageable safety profile. Combining LINVO with an anti-CD38 mAb, such as DARA or ISA, may provide additional benefit to pts with RRMM. Here we report pooled safety and efficacy results from the LINVO + DARA and LINVO + ISA cohorts during the dose-finding portion of the Phase 1b LINKER-MM2 trial (NCT05137054).

Methods

Eligible pts were aged ≥18 years with RRMM that progressed after ≥3 lines of therapy (LoTs), or ≥2 LoTs if TCE or double-class refractory (immunomodulatory drug [IMiD] + proteasome inhibitor [PI]). Prior treatment (tx) with DARA or ISA was allowed if previously tolerated and ≥6 months (mos) or ≥3 mos washout, respectively, had elapsed since last exposure. Tx began with LINVO monotherapy (Cycle [C]0; 28-day cycle) consisting of 2 step-up doses (5 mg, 25 mg) and 2 full doses (dose level [DL]1 100 mg; DL1b 150 mg; DL2 200 mg) before standard dosing of DARA or ISA was added at C1. LINVO was given once weekly in C1–3 and once every 2 weeks in C4+. At the end of 2024, dosing once every 4 weeks was implemented after C6 if a very good partial response or better (≥VGPR) was achieved. Dexamethasone premedication was required during the first 2 cycles and then given per label for DARA or ISA. Primary endpoints: dose-limiting toxicities (DLTs) and tx-emergent adverse events (TEAEs). Key secondary endpoints: overall response rate (ORR), duration of response (DOR), progression-free survival (PFS), and rate of minimal residual disease (MRD) negativity. The analyses reported here combine the LINVO + DARA and LINVO + ISA cohorts.

Results

As of May 7, 2025, 42 pts were enrolled. All pts were included in the safety analysis set: DL1 (DARA, n=12; ISA, n=6), DL1b (n=6; n=10), or DL2 (n=8; n=0); 37 were included in the efficacy analysis set: DL1 (DARA, n=11; ISA, n=5), DL1b (n=5; n=9), or DL2 (n=7; n=0). At baseline, all pts had received ≥1 PI (refractory to ≥1 PI: 76%) or ≥1 IMiD (refractory to ≥1 IMiD: 86%), and 21 pts (50%) had received prior DARA or ISA (refractory to DARA or ISA: 33% [DARA, n=4; ISA, n=10]). Median number of prior LoTs was 3 (range 2–8), including 50% of pts with TCE and 21% with triple-class refractory disease. Median age was 68 years (range 42–86); male, 57%; ISS stage III at study entry, 12%; high-risk cytogenetics, 31%; bone marrow plasma cells ≥50%, 31%; and soft tissue plasmacytomas, 33% (extramedullary, 12%). Median follow-up duration was 14.8 mos for DL1 (DARA 21.3; ISA 11.3), 7.6 mos for DL1b (DARA 13.5; ISA 5.2), and 5.9 mos for DL2 (all DARA), with 44%, 50%, and 63% of pts still receiving tx, respectively. The most common TEAEs were anemia (any grade [Gr] 48%; Gr 3/4 26%), neutropenia (41%; 41%), diarrhea (38%; 2%), and thrombocytopenia (38%; 17%). Cytokine release syndrome was reported in 33% of pts (all Gr 1/2 events except 1 Gr 3 event during the step-up period that fully resolved). No pts experienced immune effector cell-associated neurotoxicity syndrome (ICANS). Infections were reported in 32 pts (any Gr 76%; Gr ≥3 40%), and 3 resulted in death (1 tx related: cytomegalovirus [CMV] pneumonia; 2 tx unrelated: C. diff colitis and lower respiratory infection). One DLT was observed at DL1b in the ISA cohort (Gr 3 Epstein–Barr virus pharyngitis) and 1 was observed at DL2 in the DARA cohort (Gr 5 CMV pneumonia). Among efficacy evaluable pts, ORR was 75% at DL1 (12/16; ≥VGPR rate 75%), 93% at DL1b (13/14; ≥VGPR rate 57%), and 86% at DL2 (6/7; ≥VGPR rate 86%). Of 10 MRD-evaluable pts, all were MRD negative (

ABSTRACT

Allogeneic hematopoietic cell transplantation (HCT) remains inaccessible to many patients, particularly those of non-European ancestry, due to the limited availability of matched unrelated donors (URD). While single-HLA mismatched donors (7/8) often yield acceptable outcomes, URD HCT mismatched at ≥ 2 HLA alleles (

Background:

Surgical management has greatly evolved from a radical mastectomy to the most recent advancement of a more conservative oncoplastic breast surgery (OBS). It has not only proven to be safe, but also has shown superior cosmetic outcomes compared to standard breast conservation surgery as it is able to address larger and even multi-focal tumors. Nevertheless, this is a relatively novel concept in our developing country with a limited number of professionals trained in the field. Furthermore, there is a financial aspect and stigma to take into consideration. Patients have to pay out of pocket for treatment which deters them from risking the possibility of a second surgery – in case of incomplete resection margins. It also adds the burden on the surgeon to deliver optimal cosmetic outcomes with no intervention to the contralateral breast. The purpose of this study is to determine the long-term oncological and cosmetic outcomes of patients with early-stage breast cancer who underwent OBS at our institution. Methodology: A single-center retrospective study was conducted on adult female patients with biopsy proven Stage I to III breast cancer who underwent OBS from January 2017 to June, 2022. Patients who underwent bilateral breast surgery were excluded. A total of 194 women were eligible for the study and data was extracted from patient records to determine the long term oncologic outcomes— breast cancer recurrence, disease-free survival (DFS), and overall survival (OS). Cosmetic outcomes were evaluated via patient-reported satisfaction using the Harvard breast cosmesis scale, through telephonic interview after obtaining informed verbal consent. The study was approved by the institutional Ethical Review Committee (ERC 2025-11482-34955). Results:

The mean age of women at diagnosis was 48.3 ± 13.2 years with 81% having invasive ductal carcinoma. Sixty-seven percent of the women had hormone receptor positive breast cancer, while 20% had triple negative disease. Among all the patients who were included in the study, half of the patients received neoadjuvant chemotherapy before OBS, followed by adjuvant radiation therapy. Of note, only 6 (3.1%) out of 194 women had a positive margin for which they underwent a second procedure. Level 1 OBS was performed among 77% of the patients. Among those who underwent Level 2 OBS a variety of local perforator flaps were performed. We had a 68% response rate among the patients who were approached via telephone to determine the self-reported cosmetic outcomes, with 91% of the participants reporting ‘Good’ (51%) or ‘Excellent’ (40%) cosmetic outcomes when compared to the contralateral breast. Eight (4.1%) out of 16 patients had an ipsilateral recurrence, while the remaining developed distant metastases. The Kaplan Meier analysis showed that the mean OS of the study participants was 96 months (95% CI=92.2-99.7) since diagnosis, with death as the outcome event. The mean DFS was 93 months (95% CI=89.5 – 97.6) since diagnosis until recurrence as the outcome event. There were significant differences in survival times for patients by recurrence (log rank test, p=0.000) and hormone receptor status (log rank test, p=0.015). There was no significant difference in survival times for patients by type of OBS (log rank test, p=0.860).

Conclusion:

Oncoplastic breast surgery is a safe and effective option for early-stage breast cancer, with low margin positivity and favorable long-term outcomes. Our study demonstrates excellent survival and high patient-reported cosmetic satisfaction, especially with Level 1 OBS. These findings support its broader use—even in resource-limited settings—as a balanced approach to oncologic safety and aesthetic outcomes.

Introduction: The CARTITUDE-4 study (NCT04181827), which enrolled patients with lenalidomide-refractory multiple myeloma (MM) after 1–3 prior lines of therapy (pLOT), demonstrated a significant benefit of ciltacabtagene autoleucel (cilta-cel) over established triplet regimens. However, the benefit of cilta-cel for patients with standard-risk cytogenetics remains less defined. Here, we report outcomes in patients with standard-risk cytogenetics from the intent-to-treat and as-treated populations in CARTITUDE-4.

Methods: InCARTITUDE-4, patients randomized to the cilta-cel arm underwent apheresis and bridging treatment with either pomalidomide, bortezomib, and dexamethasone (PVd) or daratumumab, pomalidomide, and dexamethasone (DPd), followed by lymphodepletion therapy with cyclophosphamide and fludarabine, and then a single cilta-cel infusion. Progression-free survival (PFS) was assessed using a validated computerized algorithm. The intent-to-treat population included 208 patients; 32 patients progressed or died on bridging therapy, resulting in an as-treated population of 176 patients. Patients with high-risk cytogenetics, defined as del(17p), t(14;16), t(4;14), gain/amp(1q) (n=105), or with unknown cytogenetics (n=12), were excluded from the as-treated analysis. The 12-month minimal residual disease (MRD)-negative complete response (CR) was defined per the International Myeloma Working Group criteria as the proportion of participants with CR or better prior to and at 12 months (±3 months), achieving MRD-negative status at 12 months (+3 months) after cilta-cel infusion, as determined by next-generation sequencing (10-5), prior to progressive disease or subsequent anti-myeloma therapy. For the as-treated population, PFS rates were measured from the time of cilta-cel infusion.

Results: In CARTITUDE-4, in the intent-to-treat population, at a median follow-up of 33.6 months, patients with standard-risk cytogenetics had a 30-month PFS rate (95% CI) of 71.0% (58.8–80.2) in the cilta-cel arm (N=69) vs 43.2% (31.3–54.5) in the standard-of-care (SOC) arm (N=70). Patients with standard-risk cytogenetics in the as-treated population (n=59) had a 30-month PFS rate of 80.5% (95% CI, 67.2–88.8). In CARTITUDE-1 (NCT03548207), which evaluated cilta-cel in patients with heavily pretreated relapsed/refractory MM (RRMM; ≥3 pLOT), the 30-month PFS rate among patients with standard-risk cytogenetics (negative for del(17p), t(14;16), or t(4;14); n=68) was 59.9% (95% CI, 47.2–70.5). In the CARTITUDE-4 as-treated population with standard-risk cytogenetics, 8 PFS events occurred within 1 year and 4 PFS events beyond 1 year of cilta-cel infusion. Twenty-six patients achieved MRD-negative CR at 12 months after cilta-cel; 100.0% of these patients were progression free at 30 months. Fourteen patients were not evaluable for MRD due to: calibration failure (n=12), no sample availability for testing (n=1), or indeterminate results post baseline (n=1).

Conclusions: The PFS rate at 2.5 years for patients with standard-risk RRMM was higher in CARTITUDE-4 compared with CARTITUDE-1, supporting the use of cilta-cel as early as second line in the treatment course. In CARTITUDE-4 (as-treated population), 80.0% of patients with standard-risk cytogenetics were progression free and off treatment at 2.5 years. In patients with standard-risk disease who achieved MRD-negative CR at 1 year, this rate increased to 100.0%. The low rate of progression events in cilta-cel-treated patients with standard-risk cytogenetics shows the profound benefit of a single cilta-cel infusion in this population.

BACKGROUND:

The optimal adjuvant endocrine therapy (ET) for patients (pts) with hormone receptor-positive (HR+)/HER2-positive (HER2+) early breast cancer (EBC) remains controversial. The present analysis investigated the efficacy of different types of ET in pts with centrally tested HR+/HER2+ EBC treated with modern chemotherapy (CT) and trastuzumab (T)-based regimens at 10-year follow-up.

Patients and methods: ALTTO (BIG 2-06) is an international phase 3 trial in pts with HER2+ EBC randomized to 4 adjuvant anti-HER2 treatments with CT: T alone, lapatinib (L) alone, their sequence (T->L) or their combination (T+L). Pts in the L alone arm, pts with HR-/HER2+ disease and pts with HR+ tumours who did not start adjuvant ET were excluded from the analysis. HER2 and HR status were centrally tested for all pts. Disease-free survival (DFS), time to distant recurrence (TTDR) and overall survival (OS) were compared between pts who received a selective estrogen receptor modulator (SERM) vs. those who received an aromatase inhibitor (AI). To avoid the risk of immortal time bias, pts with HR+/HER2+ disease who switched from one ET to another during the follow-up were excluded. A pre-planned subgroup analysis according to menopausal status at baseline was performed. Among premenopausal women, a comparison was made between SERM alone, SERM + ovarian function suppression (OFS) and AI±OFS (depending on post-CT menopausal status). Multivariable Cox proportional hazards regression models were used to model survival outcomes with adjuvant ET as the predictor. Other covariates in the model were CT timing (concurrent/sequential), tumour grade (G1/2, G3, GX), age (continuous) and tumour size (T, continuous) and a strata variable of axillary lymph node (N0, N1-3, N>=4 nodes, N/A). SERM were used as the reference category for adjusted hazard ratios (aHR).

RESULTS:

This analysis included 2,651 pts with HR+/HER2+ of whom 1,518 (57.3%) received SERM (99.5% tamoxifen) and 1,133 (42.7%) AI. Among 1,259 premenopausal pts, 903 (71.7%) received SERM alone, 238 (18.9%) SERM+OFS and 118 (9.4%) AI±OFS. Median follow-up was 9.9 years (IQR 7.0-10.0 years). Overall, 10-year DFS was 80.1% and 76.5% in the AI and SERM groups, respectively (aHR 0.65; 95% CI 0.52-0.82). Compared to pts treated with SERM, those who received AI had fewer local (0.9% vs. 2.4%) and distant (9.3% vs. 12.1%) recurrences. In subgroup analyses, AI was superior to SERM irrespective of pts (age, menopausal status, body mass index), tumor (T, N, G, HR+ levels, HER2 FISH ratio) and treatment (anti-HER2 arm, CT type and timing) characteristics. In the AI and SERM groups, 10-year TTDR was 85.7% and 83.1% (aHR 0.65; 95% CI 0.50-0.85), and 10-year OS was 88.9% and 89.1% (aHR 0.73; 95% CI 0.53-1.00), respectively. Among premenopausal pts only, 10-year DFS was 90.0%, 77.3% and 77.6% with AI±OFS, SERM+OFS and SERM, respectively (AI±OFS vs. SERM: aHR 0.44; 95% CI 0.23-0.85; SERM+OFS vs. SERM: aHR 0.87; 95% CI 0.61-1.23). In the AI±OFS, SERM+OFS and SERM groups, 10-year TTDR was 92.8%, 82.9% and 85.1% (AI±OFS vs. SERM: aHR 0.57; 95% CI 0.27-1.18; SERM+OFS vs. SERM: aHR 0.94; 95% CI 0.62-1.41), and 10-year OS was 95.6%, 88.7% and 91.3% (AI±OFS vs. SERM: aHR 0.68; 95% CI 0.27-1.73; SERM+OFS vs. SERM: aHR 0.98; 95% CI 0.58-1.66), respectively.

CONCLUSIONS:

In this large 10-year follow-up analysis of pts with centrally tested HR+/HER2+ EBC treated with modern CT+anti-HER2-based therapy in the ALTTO trial, the use of AI was associated with significantly improved DFS and TTDR without differences in OS. The DFS benefit of AI was observed in both premenopausal and postmenopausal pts. These data may help optimizing adjuvant ET choices in pts with HR+/HER2+ EBC and shed light on the need of designing ad hoc clinical trials in this setting.

ABSTRACT

Introduction: Measurable residual disease (MRD) prior to consolidation therapy is a strong prognostic biomarker for relapse and long-term survival in acute myeloid leukemia (AML). Beyond its prognostic role, MRD is increasingly used to guide therapeutic decisions. A logical next step is regulatory acceptance of MRD as a (co-)primary endpoint in AML, as recently granted by the FDA for MRD in multiple myeloma. However, acceptance in AML is hampered by disease heterogeneity, variability in MRD assessments and a lack of trial-level validation. As MRD-guided treatment becomes more common, future trial outcomes may be confounded by such interventions. Thus, establishing MRD now as a surrogate endpoint is critical to enable accelerated drug approval in AML. Here, we evaluate both individual- and trial-level surrogacy of MRD assessed by multiparameter flow cytometry (MFC) and qPCR for mutant NPM1 using harmonized patient-level data from seven prospective randomized phase II/III trials.

METHODS:

We included patient-level data from 1,858 adult with AML enrolled in trials conducted by AMLSG, HOVON-SAKK, SAL, and UK-NCRI, collected through the HARMONY Alliance. Eligible trials involved randomization to experimental or placebo treatment added to a standard intensive induction chemotherapy, with ≥20 patients per arm and per MRD subgroup. Patients were included if they had a MRD assessment after two chemotherapy cycles by either MFC or qPCR for mutant NPM1. Data were harmonized using the OMOP common data model. Following FDA guidance, we analyzed two levels of surrogacy. For individual-level surrogacy, we examined the association between MRD status and overall survival (OS) using Plackett’s copula models and multivariable Cox regression. For trial-level surrogacy, we quantified the relationship between treatment effects on MRD and OS using hazard ratios (HR) and odds ratios (OR) in weighted least-squares regression. A coefficient of determination (R²) >0.8 with 95% CI lower bound >0.6 was considered strong trial-level surrogacy, consistent with previously accepted surrogate endpoints. Subgroup analyses were conducted by MRD method and transplant status.

RESULTS:

The included trials were AMLSG 09-09 (qPCR MRD assessment), three HOVON-SAKK trials (AML-102, AML-103, AML-132; all MFC), the SAL cohort (qPCR), and the UK-NCRI AML17 trial, which included two separate randomizations (both MFC- and qPCR-MRD).

In multivariable analysis, MRD positivity was associated with significantly worse OS across the cohort (HR: 1.66, 95% CI: 1.33–2.07, p

ORLANDO, Florida—Total body irradiation before allogeneic hematopoietic cell transplantation can be avoided in patients with B-cell lymphomas if you monitor their initial treatment responses by assessing minimum residual disease using next generation sequencing rather than by traditional flow cytometry.

This finding has emerged from the phase two EndRAD trial reported at the 2025 Annual Meeting of the American Society of Hematology by Hisham Abdel-Azim MD MS, Chief, Division of Transplant/Cell Therapy and Hematological Malignancies, Cancer Center, Departments of Pediatrics and Medicine, Loma Linda University School of Medicine, Children Hospital and Medical Center, Loma Linda CA, United States.

ABSTRACT

Introduction: HCT is an established curative treatment for children, adolescents, and young adults (CAYA) with high-risk/relapsed B-ALL. Inclusion of TBI in HCT conditioning has been shown to be superior to non-TBI approaches for B-ALL, but is associated with significant late effects. Based upon retrospective data showing low rates of relapse, we hypothesized that patients with negative pre-HCT MRD by next-generation-sequencing of IgH B-cell receptor rearrangements (NGS-MRD) could achieve 2-year EFS exceeding 75% with a non-TBI regimen, an outcome comparable to those receiving TBI-based regimens.

METHODS:

The Pediatric Transplantation and Cellular Therapy Consortium (PTCTC) conducted a phase II prospective trial at 45 centers in North America (ONC1701 EndRAD: NCT03509961) between 2018 and 2025 to evaluate outcomes of myeloablative non-TBI conditioning regimens for allogeneic HCT in B-ALL patients at lower risk for relapse defined by absence of NGS-MRD (Clonoseq) of B-cell receptor rearrangements (BCR) just prior to HCT. Eligibility criteria included age >/= 1 year to /=14 yrs old). Relapses occurred in 6 children, with 4 (67%) undergoing HCT in CR2. Four of the six relapses occurred after matched sibling donor HCT. Acute GVHD occurred in 20 patients (39%, with 15 (75%) grade 1-2 and 5 (25%) grade 3-4). Chronic GVHD occurred in 13 patients (25%) (11 (85%) requiring systemic immunosuppressive treatment).

CONCLUSIONS:

The primary endpoint of our study was met with the 2-year EFS exceeding 75% following non-TBI conditioning and allogeneic HCT in pre-HCT NGS-MRD negative B-ALL. OS in our cohort is comparable to published Center for International Blood & Marrow Transplant Research (CIBMTR) results in B-ALL where patients receive TBI-based conditioning. Our results show that pre-HCT NGS-MRD can be used to allow the choice of myeloablative non-TBI preparative regimens for CAYA undergoing allogeneic HCT that may result in decreased late effects. Additional analyses to be reported at the meeting will more fully investigate factors that impact post-HCT outcomes, including baseline cytogenetics/genomics and post-HCT bone marrow and peripheral blood NGS-MRD, along with planned comparisons to an observational cohort (n=146) enrolled on the trial including infants and older patients treated non-TBI approaches and older children treated with TBI-based regimens.

Background:

Adjuvant (adj) endocrine therapy (ET) is the mainstay treatment (tx) for estrogen receptor-positive, HER2-negative early breast cancer (ER+ HER2- eBC). However, up to 1/3 of patients (pts) eventually experience recurrence. Clinically, there is an unmet need for more tolerable and efficacious ET to improve adherence and pt outcomes. Giredestrant, a next-generation oral selective estrogen receptor antagonist and degrader (SERD), was shown to be more potent than other SERDs (Liang 2021; Bardia 2023) and demonstrated superior antiproliferative activity vs anastrozole in the neoadj coopERA BC trial (Hurvitz 2023). Results of the prespecified interim analysis of the global, randomized lidERA BC trial (NCT04961996) are presented.

Methods: Pts with Stage I-III ER+ HER2- eBC were randomized 1:1 to giredestrant 30 mg oral daily (with an LHRH agonist in pre- and peri-menopausal women, and men) or standard-of-care ET (tamoxifen or aromatase inhibitor) for 5 years (yr). The primary endpoint was invasive disease-free survival (IDFS). Key secondary endpoints were overall survival (OS), distant recurrence-free interval (DRFI), and safety.

Results: 4170 pts were randomized (Aug 2021-Sep 2023): 2084 to giredestrant; 2086 to standard-of-care ET. Median age was 54.0 yr; 59.3% of pts were postmenopausal; 13.0%, 47.4%, and 39.6% had Stage I, II, and III BC, respectively. Median follow-up at clinical cutoff (Aug 8, 2025) was 32.3 months, with 336 IDFS events. Efficacy is shown in the table. Giredestrant demonstrated superior IDFS vs standard-of-care ET (hazard ratio [HR] 0.70; 95% confidence interval [CI], 0.57, 0.87; p = 0.0014). 3-yr IDFS rates were 92.4% and 89.6%, respectively. There was a trend towards OS improvement in the giredestrant arm vs the standard-of-care ET arm (HR 0.79; 95% CI, 0.56,1.12). The DRFI HR was 0.69 (95% CI, 0.54, 0.89). The most common adverse events (AEs) in the giredestrant vs standard-of-care ET arms, respectively, were arthralgia (48.0% vs 47.1%), hot flush (27.4% vs 28.8%), and headache (15.3% vs 13.2%); the most common Grade 3-4 AEs, hypertension (2.6% vs 2.0%) and arthralgia (1.5% vs 1.8%). Discontinuations due to AEs occurred in 5.3% with giredestrant vs 8.2% with standard-of-care ET.

Conclusions: lidERA BC is the first Phase III trial to demonstrate benefit with an oral SERD in eBC. Giredestrant tx resulted in a statistically significant and clinically meaningful IDFS improvement vs standard-of-care ET in ER+, HER2- eBC. OS trended in favor of the giredestrant arm, and DRFI was improved vs standard-of-care ET. The safety profile was favorable and consistent with known profiles, and the discontinuation rate was slightly lower with giredestrant compared with standard-of-care ET. Overall, the results support giredestrant as a potential new standard for pts with HR+ eBC.

PRESS RELEASE:

Novel Endocrine Therapy Giredestrant Improves Disease-free Survival Over Standard of Care for Patients With Early-stage Breast Cancer in Phase III lidERA Trial

SAN ANTONIO – The investigational, oral selective estrogen receptor degrader (SERD) giredestrant given as an adjuvant therapy showed significant improvement in invasive disease-free survival (iDFS) compared with the current standard-of-care endocrine therapy in patients with early-stage, hormone receptor (HR)-positive, HER2-negative breast cancer, according to the results of the phase III IidERA trial presented at the San Antonio Breast Cancer Symposium (SABCS), held December 9-12, 2025.

“For patients with HR-positive breast cancer—which accounts for about 70% of breast cancer cases— effective adjuvant therapy at the early stage offers a real opportunity to eradicate micrometastatic disease and improve survival in the curative setting,” said presenter Aditya Bardia, MD, MPH, professor of medicine and director of translational research integration at the University of California, Los Angeles Jonsson Comprehensive Cancer Center. “Currently, up to a third of these patients eventually experience recurrence on or after adjuvant endocrine therapy for early breast cancer, and many struggle with tolerating treatment. A more effective, more tolerable treatment option is needed.”

In the global, randomized, open-label, multicenter trial, Bardia and colleagues enrolled patients with HR- positive, HER2-negative breast cancer in stages 1-3 to evaluate the safety and efficacy of giredestrant compared with the current standard-of-care therapies. All patients enrolled had received surgery and, if indicated, completed adjuvant or neoadjuvant chemotherapy. The median age of participants was 54, and 59% were postmenopausal.

In the randomized clinical trial, the researchers assigned 4,170 patients 1:1 to receive either 30 mg of giredestrant or one of four standard-of-care endocrine therapies selected at the discretion of the prescribing physician: tamoxifen, letrozole, anastrozole, or exemestane. Patients received their treatment daily for every 28-day cycle until five years had passed or unacceptable toxicity had occurred.

The researchers assessed patients for the primary endpoint of iDFS, and secondary endpoints included overall survival (OS) and distant recurrence-free interval (DRFI).

The trial met its primary endpoint at a prespecified interim analysis. After a median follow-up of 32.3 months, patients who received giredestrant had significantly better iDFS than their counterparts who received standard-of-care endocrine therapy and were 30% less likely to develop invasive disease progression at the time of follow-up.

The secondary endpoint of DRFI was also met. Patients who received giredestrant were 31% less likely than those in the standard-of-care arm to experience distant recurrence at the time of follow-up.

“Giredestrant demonstrated clinically meaningful superiority to currently well-established standard-of-care endocrine agents: aromatase inhibitors and tamoxifen,” Bardia said. “What is particularly striking and relevant is early separation of curves,” he added, referring to the preliminary OS data. Due to the limited follow-up window, the OS data were immature but showed a positive trend in favor of giredestrant over the standard of care, he explained.

The most common treatment-emergent adverse events (TEAEs) in both the giredestrant and standard-of- care arms were arthralgia, hot flashes, and headache (all of which were primarily low grade and nonnonserious), and the frequency of all of these TEAEs were similar between arms. Grade 3 and 4 TEAEs included hypertension and arthralgia. Few patients died of TEAEs (six and 16 patients died in the giredestrant and standard-of-care arms, respectively), with no treatment-related deaths in the giredestrant arm (one in the standard-of care arm).

Bradycardia—a known class effect of oral SERDs, according to Bardia—was higher in the giredestrant arm at 11.3% than in the standard-of-care arm at 3.2%. The majority were grade 1, asymptomatic, and nonserious, not requiring treatment interruption/discontinuation. Grade 2 adverse events (

Abstract Body, Introduction:

Over 90% of children with acute lymphoblastic leukemia (ALL) will survive their cancer in the context of >2 years of multi-agent chemotherapy. This intensive treatment paradigm may lead to significant treatment-related financial toxicity for families— an outcome highly relevant to long-term child and family well-being. The magnitude and trajectories of financial toxicity are unknown in pediatric oncology, and necessary to inform optimal screening and intervention strategies for children with cancer and their families. Development of new household material hardship ([HMH], housing, food, or utility insecurity) or income loss during cancer treatment are concrete, targetable metrics of financial toxicity.

We present results from Dana-Farber Cancer Institute (DFCI) ALL Consortium Trial 16-001, the first pediatric oncology clinical trial to systematically collect longitudinal HMH and household income data as an embedded correlative trial aim.

Background

Adjuvant chemotherapy (ACT) benefit is uncertain for any individual patient (pt). Post-surgery circulating tumour DNA (ctDNA) testing could support risk-adjusted treatment selection. The DYNAMIC-III study explored ACT de-escalation or escalation, informed by post-surgery ctDNA results.

Methods

In this multicentre, randomised, phase II/III trial, pts with stage III colon cancer underwent tumour-informed ctDNA testing 5-6 weeks post-surgery and were randomised (1:1) to ctDNA-guided or standard management. Clinicians pre-specified standard ACT. In the ctDNA-guided arm, ctDNA-negative results prompted ACT de-escalation: from 6 to 3 months of fluoropyrimidine (FP) or observation, from 3 months of doublet to single-agent FP, or from 6 months of doublet to 3 months doublet or single-agent FP. The primary endpoint was 3-year recurrence-free survival (RFS). A sample size of 750 provided 80% power with a one-sided 97.5% CI to demonstrate non-inferiority (NI) with a NI margin of 7.5%.

Results

Of 968 evaluable pts, 702 (72.5%) were ctDNA-negative; 353 assigned to ctDNA-guided and 349 to standard management. Median follow-up was 45 months. 319 (90.4%) pts received ctDNA-guided per-protocol de-escalation. Treatment de-escalation reduced oxaliplatin-based chemotherapy use versus standard management (34.8% vs 88.6%, P < 0.001) and lowered grade 3+ adverse events of special interest (6.2% vs 10.6%, P = 0.037) and treatment-related hospitalisation (8.5% vs 13.2%, P = 0.048). However, non-inferiority of ctDNA-guided de-escalation was not confirmed (3-year RFS, 85.3% vs 88.1%; difference = -2.8%; 97.5% lower CI = -8.0%). Pre-planned subgroup analysis suggested de-escalation may be non-inferior in clinical low-risk (T1-3N1) tumours (3-year RFS, 91.0% vs. 93.2%; difference = -2.2%; 97.5% lower CI = -7.2%).

Conclusions

Stage III colon cancer pts with negative post-surgery ctDNA had low recurrence risk. ctDNA-guided de-escalation is feasible, substantially reduces oxaliplatin exposure and adverse events, with outcomes approaching standard management, especially for clinical low-risk tumours.

Background

The CDK4/6 inhibitors (CDK46/i) are approved for early-stage HR+/HER2− breast cancer (BC). The randomized neoadjuvant NeoPAL and CORALLEEN trials provided proof of concept that CDK4/6i in combination with endocrine therapy (ET) have similar activity to multi-agent chemotherapy in pts with luminal B-PAM50 based- BC subtype. The PAM50-derived ROR score was identified as an endpoint of interest after neoadjuvant CDK4/6i-ET. The RIBOLARIS trial was designed to evaluate whether pts with ROR-low disease following neoadjuvant ribociclib (RIB) and ET can safely omit adjuvant chemotherapy.

Methods

RIBOLARIS is an open-label, single-arm, multicenter trial in pts with primary operable stage II, grade 2/3, Ki67 ≥20%, HR+/HER2− BC who are candidates for adjuvant chemotherapy. The study evaluates safety and long-term efficacy of a non-chemo regimen (RIB-ET) in pts with tumors showing a ROR-low score after 6 neoadjuvant cycles of RIB-ET (600 mg/day 3 weeks ON/1 week OFF + ET: letrozol 2.5 mg/day) followed by surgery (within 10 days). Pts with ROR-med/high tumors will receive chemotherapy-based treatment followed by RIB-ET. This preplanned Interim Analysis analyzed safety and efficacy after 686 surgeries. We expected at least 40% of the pts to achieve a ROR-low score after neoadjuvant RIB-ET.

Results

Among the enrolled pts, baseline characteristics included: median age 57 (38-84), postmenopausal status 62%, tumor stage IIA 60%, node-negative 60%, and histological grade 2 74%. At data cut-off, 686 out of 1100 surgeries (62.4%) were performed. Interestingly, we observed that 361 pts (52.6%) achieved a ROR-low score (Mean 11.3, 95% CI 10.5-12.2), while 325 pts (47.4%) had a med/high ROR score (Mean 36.9, 95% CI 34.2-39.5). The most common grade 3-4 severity TEAEs were neutropenia (grade 3: 46.3%; grade 4: 3.5%) and transaminases increased (grade 3: 10.4%; grade 4: 1.5%).

Conclusions

These preliminary results from the RIBOLARIS trial confirm and extend the findings from CORALLEEN and NeoPAL trials, demonstrating that a subset of pts with early-stage HR+/HER2− BC achieve ROR-low disease after neoadjuvant RIB-ET and may be candidate to spare chemotherapy. There was no new safety signal.

An interview with Li Zhang MD, Medical Oncologist and Full Professor, Sun Yat-sen University Cancer Center, Guangzhou, China

BERLIN, Germany—A doubling of progression-free survival, and highly statistically significant benefit for overall survival, has been achieved in patients with epidermal growth factor- (EGFR-) mutated non-small cell lung cancers that had become refractory to EGFR tyrosine kinase inhibitor therapy in a study in which treatment with the antibody drug conjugate (ADC) sacituzumab tirumotecan was compared with standard platinum-based chemotherapy.

At the 2025 Annual Congress of the European Society for Medical Oncology (ESMO) Professor Li Zhang MD, a medical oncologist and full professor at Sun Yat-sen University Cancer Center in Guangzhou, China, reported findings from the randomized, multi-center phase III OptiTROP-Lung04 study at a late-breaking session.

Background

Sac-TMT is a TROP2 ADC developed with a novel linker to conjugate the payload, a belotecan-derivative topoisomerase I inhibitor. Sac-TMT demonstrated significant survival benefits over docetaxel in EGFRm NSCLC after failure of EGFR-TKI and platinum-based chemotherapy (Fang et al., BMJ 2025). Here, we first report the final PFS analysis and preplanned interim OS analysis results from the phase 3 OptiTROP-Lung04 study (NCT05870319).

Methods

Patients (pts) were randomized (1:1) to receive sac-TMT monotherapy (5 mg/kg Q2W) or chemotherapy (pemetrexed 500 mg/m2 + carboplatin AUC 5 or cisplatin 75 mg/m2 Q3W for 4 cycles followed by maintenance of pemetrexed). The primary endpoint was PFS assessed by blinded independent review committee (BIRC) with OS as a key secondary endpoint tested hierarchically.

Results

A total of 376 pts (median age 59.5 yrs; 39.6% male; 79.3% ECOG PS 1; 94.7% prior 3rd-generation EGFR TKI) were randomized to the sac-TMT (n=188) or chemotherapy (n=188) groups. At a median follow-up of 18.9 mo, 21.3% of pts (sac-TMT) vs 1.6% (chemotherapy) remained on treatment. Sac-TMT demonstrated highly statistically significant and clinically meaningful improvements in PFS and OS compared to chemotherapy (Table). Grade ≥ 3 TRAEs occurred in 49.5% and 52.2%, and TRSAEs in 7.4% and 17.0% of pts in sac-TMT and chemotherapy arms, respectively. No drug-related interstitial lung disease/pneumonitis occurred in either arm.
