| Main Objective: Part A: The primary objective of the dose-optimization part of the study is to determine the RP2D taking into account DLT/s in Cycle 1, overall safety/tolerability and PK, by optimizing doses of Debio 1143 when combined with the standard dose of nivolumab, as well as treatment compliance in patients with advanced solid malignancies who failed prior systemic standard treatments. Part B: The primary objective of the basket trial is 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 patient cohort. ; Secondary Objective: Part A: For the dose-optimization part, secondary objectives are to assess the: 1. PK disposition of Debio 1143 (including its metabolite Debio 1143-MET1) and nivolumab when administered in combination. 2. Anti-tumor activity of Debio 1143 in combination with nivolumab in patients with advanced solid malignancies. Part B: For the basket trial, secondary objectives are to assess the: 1. Safety and tolerability of the RP2D of Debio 1143 when given in combination with nivolumab in patients with advanced solid malignancies. 2. PK disposition of Debio 1143 (and its metabolite Debio 1143-MET1) and nivolumab when administered in combination. ; Primary end point(s): PART A: The primary endpoint of part A is the RP2D of Debio 1143 when combined with the standard dose of nivolumab, in patients with advanced solid malignancies who received prior systemic standard treatment and failed a prior PD-1/PD-L1-containing treatment, as per DLT occurrence in less than one-third of evaluable treated patients at the RP2D dose | — |
