Study to Evaluate Safety and Effectiveness of BNT324 and BNT327 Combination Therapy in Adults with Advanced or Metastatic Lung Cancer

What this Trial Is About

Researchers are evaluating the combination of BNT324, a B7-H3 antibody-drug conjugate, with BNT327, a bispecific antibody targeting PD-L1 and VEGF, in participants with advanced, metastatic, or relapsed small cell lung cancer SCLC and non-small cell lung cancer NSCLC. This multi-part study aims to find safe doses, optimize treatment, assess preliminary effects, and confirm clinical efficacy in different lung cancer groups. The study includes participants with confirmed lung cancer who have measurable disease and meet specific health criteria. Participants will receive intravenous infusions of BNT324 combined with BNT327 in a dose escalation design to establish two recommended dose levels RP2D and RP2D-1. The study has two parts Part 1 focuses on dose finding in NSCLC and SCLC Part 2 compares these doses in treatment-naive and relapsed lung cancer cohorts, with some randomized groups. Additional participants may join at the optimal dose to further evaluate safety and effectiveness. Participants will undergo screening, followed by treatment, safety follow-up, and long-term survival monitoring. Researchers will assess dose-limiting toxicities, adverse events, treatment interruptions, and response rates using standardized criteria. Outcomes include objective response rate, disease control, progression-free survival, duration of response, and overall survival, with evaluations continuing up to 87 months. Safety is closely monitored during and after treatment, and participants health status is regularly assessed.
