- Conditions
- Gastric CancerGastroesophageal Junction Adenocarcinoma
- Interventions
- Registration Number
- NCT05111626
- Lead Sponsor
- Amgen
- Brief Summary
The main objective of Part 1 is to evaluate the safety and tolerability of bemarituzumab plus 5-fluorouracil, leucovorin, and oxaliplatin (mFOLFOX6) and nivolumab.
The main objective Part 2 is to compare efficacy of bemarituzumab plus chemotherapy (mFOLFOX6 or capecitabine combined with oxaliplatin (CAPOX)) and nivolumab to placebo plus chemotherapy (mFOLFOX6 or CAPOX) and nivolumab as assessed by overall survival.

Group Intervention Description Part 1 Safety Lead-in: Bemarituzumab with mFOLFOX6 and Nivolumab Bemarituzumab Participants will be administered bemarituzumab at different doses with mFOLFOX6 and nivolumab to determine the recommended phase 3 dose (RP3D) based on occurrence of dose-limiting toxicities (DLTs), and on an evaluation of the overall safety, tolerability, and pharmacokinetics (PK). Part 1 Safety Lead-in: Bemarituzumab with mFOLFOX6 and Nivolumab Nivolumab Participants will be administered bemarituzumab at different doses with mFOLFOX6 and nivolumab to determine the recommended phase 3 dose (RP3D) based on occurrence of dose-limiting toxicities (DLTs), and on an evaluation of the overall safety, tolerability, and pharmacokinetics (PK). Part 1 Safety Lead-in: Bemarituzumab with mFOLFOX6 and Nivolumab Chemotherapy Participants will be administered bemarituzumab at different doses with mFOLFOX6 and nivolumab to determine the recommended phase 3 dose (RP3D) based on occurrence of dose-limiting toxicities (DLTs), and on an evaluation of the overall safety, tolerability, and pharmacokinetics (PK). Part 2: Bemarituzumab with chemotherapy (mFOLFOX6 or CAPOX) and Nivolumab Bemarituzumab Participants will be administered bemarituzumab at the RP3D determined from Part 1 in combination with mFOLFOX6 and nivolumab on a 14-day cycle.
