Brief Summary

This study aims to investigate the combination of BNT324, a B7-H3 antibody-drug conjugate (ADC) with BNT327, a programmed death-ligand 1 (PD-L1) and vascular endothelial growth factor (VEGF) bispecific antibody, in participants with advanced/metastatic or relapsed/progressive small cell lung cancer (SCLC) and non small cell lung cancer (NSCLC).

Outcome Measures

Primary Outcomes (7)

Part 1 - Occurrence of dose limiting toxicities (DLTs) by dose level
During the DLT evaluation period, i.e., the time of initiation of the first dose of investigational medicinal product (IMP) up to 21 days]
Part 1 - Occurrence of Treatment-emergent adverse events (TEAEs), serious TEAEs, treatment-related TEAEs, and treatment-related serious TEAEs by dose level
From the time of the first dose of IMP to 90 days after the last IMP dose or until new anticancer therapy is started, whichever occurs first
Part 1 - Occurrence of dose interruption, reduction, and treatment discontinuations due to TEAEs by dose level
From the time of the first dose of IMP to 90 days after the last dose of IMP or until new anticancer therapy is started, whichever occurs first
Part 2 cohorts 1 and 2 - Occurrence of TEAEs, serious TEAEs, treatment-related TEAEs, and treatment-related serious TEAEs by cohort and treatment arm
From the time of the first dose of IMP to 90 days after the last IMP dose or until new anticancer therapy is started, whichever occurs first
Part 2 cohorts 1 and 2 - Occurrence of dose interruption, reduction, and treatment discontinuation due to TEAEs by cohort and treatment arm
From the time of the first dose of IMP to 90 days after the last IMP dose or until new anticancer therapy is started, whichever occurs first
Part 2 cohorts 1 and 2 - Objective response rate (ORR) by cohort and treatment arm
ORR defined as the proportion of participants in whom a confirmed complete response (CR) or partial response (PR) is observed as best overall response (per response evaluation criteria in solid tumors \[RECIST\] version 1.1 based on the investigator's assessment).
From the time of initiation of the first dose of IMP to end of study, i.e., up to 87 months
Part 2 cohorts 3-7 - ORR by cohort
ORR, defined as the proportion of participants in whom a confirmed CR or PR is observed as best overall response (per RECIST version 1.1 based on the investigator's assessment).
From the time of initiation of the first dose of IMP to end of study, i.e., up to 87 months

Secondary Outcomes (9)

Part 1 - ORR by dose level
From the time of initiation of the first dose of IMP to end of study, i.e., up to 87 months
Part 1 - Disease control rate (DCR) by dose level
From the time of initiation of the first dose of IMP to end of study, i.e., up to 87 months
Part 2 all cohorts - (PFS) by cohort and treatment arm
From the time of initiation of the first dose of IMP to end of study, i.e., up to 87 months
Part 2 all cohorts - Duration of response (DOR) by cohort and treatment arm
From the time of initiation of the first dose of IMP to end of study, i.e., up to 87 months
Part 2 all cohorts - Overall survival (OS) by cohort and treatment arm
From the time of initiation of the first dose of IMP to end of study, i.e., up to 87 months
+4 more secondary outcomes

Study Arms (8)
