Official title: A Phase 2 Non-randomized, Open-label, Multi-cohort, Multi-center Study Assessing the Clinical Benefit of SAR444245 (THOR-707) Combined With Other Anticancer Therapies for the Treatment of Participants With Advanced and Metastatic Gastrointestinal Cancer
Conditions: Oesophageal Squamous Cell Carcinoma
Gastric Cancer
Hepatocellular Carcinoma
Colorectal Cancer
Oesophageal Adenocarcinoma
Summary: The study is a phase 2 non-randomized, open-label, multi-cohort, multi-center study assessing the clinical benefit of SAR444245 (THOR-707) combined with other anticancer therapies for the treatment of participants aged 18 years and older with advanced and metastatic gastrointestinal cancer. This study is structured as a master protocol for the investigation of SAR444245 with other anticancer therapies.
Sub study 01 - Cohort A aims to establish proof-of-concept that combining the non-alpha-IL2 SAR444245 with the anti-PD1 antibody pembrolizumab will result in a significant increase in the percentage of patients experiencing an objective response in the setting of advanced unresectable or metastatic esophageal squamous cell carcinoma (ESCC).
Sub study 02 - Cohort B1, B2 and B3 would focus on non MSI-H tumors with a large unmet need to establish proof-of-concept that combining the non-alpha-IL2 SAR444245 with the anti-PD1 antibody pembrolizumab will result in a significant increase in the percentage of patients experiencing an objective response in the setting of advanced unresectable or metastatic gastric cancer or gastro-esophageal junction adenocarcinoma (GC/GEJ), especially with low PD-L1 expression or after progression on prior PD1/PD-L1-based regimens.
Sub study 03 - Cohort C aims to establish proof-of-concept that combining the non-alpha-IL2 SAR444245 with the anti-PD1 antibody pembrolizumab will result in a significant increase in the percentage of patients experiencing an objective response in participants with advanced unresectable or metastatic HCC who relapsed on prior PD1/PD-L1-based regimens.
Sub study 04 - Cohort D1 and D2 aims to establish proof-of-concept that combining the non-alpha-IL2 SAR444245 with either the anti-PD1 antibody pembrolizumab or with the anti-EGFR IgG1 antibody cetuximab will result in a significant increase in the percentage of patients experiencing an objective response in the setting of advanced unresectable or metastatic colorectal cancer (mCRC).

design_group_description: Participants with advanced unresectable or metastatic esophageal squamous cell carcinoma (ESCC), regardless of programmed cell death-ligand 1 (PD-L1) expression (any combined positive score [CPS]), who had received at least 1 but no more than 2 prior lines of treatment and had progressed after primary or secondary resistance to an anti-programmed cell death-1 (PD-1)/PD-L1 based regimen were included in this cohort. Participants received SAR444245 24 microgram per kilogram (mcg/kg) along with pembrolizumab 200 milligram (mg) via intravenous (IV) infusion every 3 weeks (q3w) on Day 1 of each cycle (each cycle is 21 days) (as second-line or third-line [2/3L] therapy), until disease progression (PD), unacceptable adverse event (AE) or other full permanent discontinuation criteria was met or completion of Cycle 35.

design_group_description: Cohort B1: GC/GEJ PD-1/PD-L1 naïve non-MSI-H CPS >=1; SAR444245 24mcg/kg+Pembrolizumab as 1-3L Therapy. Participants with advanced unresectable or metastatic gastric cancer (GC) or Siewert Type 2 & 3 gastro-esophageal junction adenocarcinoma (GEJ) and for whom standard of care (SOC) was not in best interest or where no SOC was established, non-high-level microsatellite instability (MSI-H) disease and had not received more than 2 prior lines of treatment that did not include an anti-PD-1/PD-L1-based regimen with the level of PD-L1 expression at baseline as CPS >=1 GC/GEJ were included in this cohort. Participants received SAR444245 24 mcg/kg along with pembrolizumab 200 mg via IV infusion q3w on Day 1 of each cycle (each cycle is 21 days) (as first to [1-]3L therapy), until PD, unacceptable AE or other full permanent discontinuation criteria was met or completion of Cycle 35.
