Global Data for BioNTech and Bristol Myers Squibb’s PD-L1xVEGF-A Bispecific Pumitamig Shows Encouraging Efficacy in Patients with Non-Small Cell Lung Cancer in ROSETTA Lung-02 Trial

About this update from Bristol-myers Squibb Company

First investigational PD-(L)1xVEGF bispecific immunomodulator to present global data showing encouraging efficacy in combination with chemotherapy in first-line non-small cell lung cancer across PD-L1 expression levels and subtypes, highlighting its potential to set a new standard of carePumitamig plus chemotherapy showed robust and consistent antitumor activity in first-line non-small cell lung cancer at both evaluated dose levels, with higher confirmed objective response rates at the lower dose of 63.6% in the non-squamous and 72.7% in the squamous subtypesPumitamig is advancing through a comprehensive global Phase 3 development program in non-small cell lung cancer, including the actively enrolling pivotal Phase 3 part of the ROSETTA Lung-02 trial, along with two additional global Phase 3 trialsMAINZ, Germany, and PRINCETON, USA, May 30, 2026 – BioNTech SE (Nasdaq: BNTX, “BioNTech”) and Bristol Myers Squibb Company (NYSE: BMY, “BMS”) today announced interim Phase 2 data from the global Phase 2/3 ROSETTA Lung-02 clinical trial (NCT06712316) evaluating the investigational PD-L1xVEGF-A bispecific immunomodulator pumitamig (also known as BNT327 or BMS-986545) plus chemotherapy in patients with previously untreated advanced non-small cell lung cancer (“NSCLC”). The data showed encouraging anti-tumor activity, with high response rates observed in both non-squamous and squamous NSCLC and at each PD-L1 expression level (TPS ˂ 1%, TPS 1 – 49%, and TPS ≥ 50%). The data are being presented today as a rapid oral presentation (abstract #8513) at the 2026 American Society of Clinical Oncology (“ASCO”) Annual Meeting in Chicago. “Despite significant immuno-oncology advances in the treatment of  non-small cell lung cancer, most advanced diseases relapse on or after a PD-(L)1 checkpoint inhibitor treatment,1 indicating that targeting this immunologic pathway alone is insufficient to achieve durable responses,” said Solange Peters, M.D., Ph.D., Lead Investigator and Director of Oncology at the University Hospital of Lausanne, Switzerland. “I am encouraged by the efficacy signal with this bispecific approach, showing robust responses across subtypes and PD-L1 levels, supporting the continued investigation of pumitamig and its potential to deliver improved outcomes for a broad range of patients with NSCLC.” The P...
