Study to Assess Safety and Efficacy of the Second Mitochondrial-derived Activator of Caspases (SMAC) Mimetic Debio 1143

Study Overview

Part A (dose-optimization)- to determine the recommended phase 2 dose (RP2D) taking into account dose-limiting toxicity (DLT/s) in Cycle 1, overall safety/tolerability and pharmacokinetic (PK), by optimizing doses of Debio 1143 when combined with the standard dose of nivolumab, as well as treatment compliance in participants with advanced solid malignancies who failed prior systemic standard treatments.

Part B (basket trial)- to evaluate the preliminary anti-tumor activity of Debio 1143 at the RP2D in combination with nivolumab at the standard dose, overall and in each participant cohort (Cohort 1: small cell lung cancer [SCLC]; Cohort 2: squamous cell carcinoma of the head and neck [SCCHN]; Cohort 3: gastrointestinal (GI) cancers with known microsatellite instability-high/mismatch repair deficiency (MSI-H/MMRd) or other deoxyribonucleic acid (DNA) damage repair (DDR) abnormalities, including homologous recombination deficiency (HRD); Cohort 4: platinum-resistant epithelial ovarian cancer [EOC], endometrial cancer, primary peritoneal cancer (PPC) or cervical cancer, with known MSIH/MMRd, hereditary/somatic mutations of the breast cancer 1 (BRCA1) and BRCA2 genes or other DNA DDR abnormalities (incl. HRD).
