Safety, Effectiveness, 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. Participants will be randomized to one of two dose levels of BNT327 plus chemotherapy for the Phase 2 part of each substudy. After the analysis of the Phase 2 data (efficacy, safety, and exposure-response), an internal review committee (IRC) will decide whether participants will be treated with BNT327 at dose level 1 or 2 in the Phase 3 part of the substudies. After dose selection, the selected dose will be used for all participants in the study. For the Phase 3 parts of both substudies, an independent data monitoring committee (IDMC) will be established as needed to provide independent review of the data during the study. The sponsor may decide not to perform or stop recruiting participants in the Phase 2 part of the study depending on data generated in the BNT327-01 (NCT06449209) and BNT327-02 (NCT06449222) studies. The sponsor may also choose not to continue all substudies.
