Summary:

      The main objective of the Phase 2 part of the study is to evaluate the efficacy of
      bemarituzumab (FPA144), a targeted antibody, in combination with modified FOLFOX6 compared to
      placebo in combination with modified FOLFOX6 in participants with advanced gastrointestinal
      cancer.
