Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Part 1 Safety Lead-in: Bemarituzumab with mFOLFOX6 and 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).
Bemarituzumab will be administered as intravenous (IV) infusion.
Other Names:
  • AMG 552
Nivolumab will be administered as IV infusion.

mFOLFOX6: 5-fluorouracil, leucovorin, and oxaliplatin will be administered as IV infusion.

OR CAPOX: oxaliplatin will be administered as IV infusion and capecitabine will be administered orally.

Experimental: Part 2: Bemarituzumab with chemotherapy (mFOLFOX6 or CAPOX) and Nivolumab

Participants will be administered bemarituzumab at the RP3D determined from Part 1 in combination with mFOLFOX6 and nivolumab on a 14-day cycle.

Or participants will be administered bemarituzumab in combination with CAPOX and nivolumab on a 21-day cycle.

Bemarituzumab will be administered as intravenous (IV) infusion.
Other Names:
  • AMG 552
Nivolumab will be administered as IV infusion.

mFOLFOX6: 5-fluorouracil, leucovorin, and oxaliplatin will be administered as IV infusion.

OR CAPOX: oxaliplatin will be administered as IV infusion and capecitabine will be administered orally.

Placebo Comparator: Part 2: Placebo with chemotherapy (mFOLFOX6 or CAPOX) and Nivolumab

Participants will be administered placebo comparator in combination with mFOLFOX6 and nivolumab on a 14-day cycle.

Or participants will be administered placebo comparator in combination with CAPOX and nivolumab on a 21-day cycle.

Nivolumab will be administered as IV infusion.
Placebo will be administered as IV infusion.

mFOLFOX6: 5-fluorouracil, leucovorin, and oxaliplatin will be administered as IV infusion.

OR CAPOX: oxaliplatin will be administered as IV infusion and capecitabine will be administered orally.

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

De-identified individual patient data for variables necessary to address the specific research question in an approved data sharing request.

IPD Sharing Time Frame

Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication have been granted marketing authorization in both the US and Europe or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities. There is no end date for eligibility to submit a data sharing request for this study.

IPD Sharing Access Criteria

Qualified researchers may submit a request containing the research objectives, the Amgen product(s) and Amgen study/studies in scope, endpoints/outcomes of interest, statistical analysis plan, data requirements, publication plan, and qualifications of the researcher(s). In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling. Requests are reviewed by a committee of internal advisors. If not approved, a Data Sharing Independent Review Panel will arbitrate and make the final decision. Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement. This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications. Further details are available at the URL below.
