The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

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).

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.
