Recently reported

DB-1303/BNT323 Phase 3 Positive · 2026-10-26
metastatic breast cancer
Primary: Progression-free survival (PFS) in the DYNASTY-Breast02 global Phase 3 trial (NCT06018337) of trastuzumab pamirtecan in HR+/HER2-low metastatic breast cancer — Met its primary endpoint demonstrating a statistically significant, yet modest improvement in progression-free survival (PFS) with trastuzumab pamirtecan compared to investigator's choice of chemotherapy (magnitude not disclosed in the release)
· 541 patients with HER2-low expression randomized 1:1 to trastuzumab pamirtecan or investigator's choice single-agent chemotherapy
· At this interim analysis for the secondary endpoint of overall survival (OS), data were not mature
· The companies said the available data suggest the potential benefit to patients would be limited in the current HR+/HER2-low metastatic breast cancer treatment landscape and that they will discuss the data and determine next steps
Safety: A higher rate of interstitial lung disease (ILD) was reported compared to prior trials, with most cases Grade 1 and 2 and severe and fatal events (Grade 3-5) in a small proportion of patients; otherwise consistent with prior trials, no new safety signals

Pumitamig Phase 2 Mixed · 2026-10-25
Primary: Confirmed objective response rate (cORR) in the global Phase 2 ROSETTA Lung-107 trial (NCT06841055) of pumitamig in combination with docetaxel in metastatic NSCLC progressed on or after first-line immunotherapy plus chemotherapy — Among 30 efficacy-evaluable patients, pumitamig plus docetaxel showed a confirmed objective response rate (cORR) of 36.7% with a disease control rate (DCR) of 90.0%
· In the overall treated population (n=50), median progression-free survival (PFS) was 6.9 months (95% CI: 4.2 – not reached), with a six-month PFS rate of 63.3%
· Median time to response was 1.4 months
· cORR by PD-L1: 42.9% TPS < 1%; 33.3% TPS 1–49%; 40.0% TPS ≥ 50%
· cORR by histology: 57.1% squamous; 30.4% non-squamous, with DCRs above 80% in all subgroups
· July 10, 2026, data cut-off included 50 patients with a median follow-up of 12.2 weeks, and 33 patients remained on treatment
Safety: Pumitamig treatment-related adverse events (TRAEs) of any grade were reported in 52.0% of patients and grade ≥ 3 TRAEs in 18.0%, leading to treatment discontinuation in four (8.0%) patients; no pumitamig-related deaths or dose-limiting toxicities (DLTs)

BNT113 Phase 2/3 Mixed · 2026-10-13
AHEAD-MERIT · unresectable head and neck squamous cell carcinoma, metastatic head and neck cancer, recurrent head and neck cancer
Primary: Progression-free survival (one of dual primary endpoints, alongside overall survival, in the Phase 3 part of AHEAD-MERIT) — did not demonstrate a statistically significant improvement in PFS versus pembrolizumab alone
· Phase 2/3 AHEAD-MERIT (NCT04534205): BNT113 plus pembrolizumab vs pembrolizumab monotherapy, first-line, unresectable recurrent or metastatic HPV16+ HNSCC expressing PD-L1
· Dual primary endpoints are progression-free survival and overall survival
· IDMC recommended the trial continue as planned to evaluate overall survival
· Under the pre-specified design, a statistically significant overall survival improvement would establish a positive trial outcome even though the PFS endpoint was not met
· BioNTech remains blinded to ongoing trial data
· No numeric PFS result was disclosed in the release
Safety: not disclosed
