Safety, Efficacy, and Pharmacokinetics of BNT327 in Combination With Chemotherapy and Other Investigational Agents for Lung Cancer

Each substudy contains a Phase 2 part followed by a Phase 3 part. In the Phase 2 part, participants will be randomized to one of two dose levels of pumitamig (also known as BNT327, BMS-986545, or PM8002) plus chemotherapy (Arm 1 and Arm 2). In the Phase 3 part, participants will be randomized to pumitamig plus chemotherapy (Arm 3) or pembrolizumab plus chemotherapy (Arm 4). In China, additional participants will be enrolled into the Phase 2 part of each substudy to receive pumitamig plus chemotherapy (Arm 1A) to further evaluate the selected Phase 3 dose. For the Phase 3 part of both substudies, an independent data monitoring committee (IDMC) and a blinded Independent Central Review (BICR) will be established. The IDMC will provide independent review of the data during the study as needed and the BICR will review all available tumor assessment scans for all treated participants and will confirm the progression of disease, if applicable. The planned study duration per study participant is up to 64 months.
