  • Adult with unresectable, locally advanced or metastatic (not amenable to curative therapy) histologically documented gastric or gastroesophageal junction adenocarcinoma
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1
  • Measurable disease or non-measurable, but evaluable disease, according to Response Evaluation Criteria in Solid Tumours version 1.1 (RECIST v1.1)
  • Participant has no contraindications to mFOLFOX6 chemotherapy or nivolumab
  • Adequate organ function as follows:
    • Absolute neutrophil count ≥ 1.5 x 10^9/L
    • Platelet count ≥ 100 x 10^9/L
    • Hemoglobin ≥ 9 g/dL without red blood cell (RBC) transfusion within 7 days prior to the first dose of study treatment
    • Aspartate aminotransaminase (AST) and Alanine aminotransaminase (ALT) <3 x upper limit of normal (ULN) (or < 5 x ULN if liver involvement)
    • Total bilirubin <1.5 x ULN (or < 2 x ULN if liver involvement or Gilbert's disease)
    • Calculated or measured creatinine clearance (CrCl) of ≥ 50 mL/minute calculated using the formula of Cockcroft and Gault

Additional Inclusion Criteria Part 2:
  • No prior treatment for metastatic or unresectable disease except for a maximum of 1 dose of mFOLFOX6 with or without nivolumab. Prior adjuvant, neo-adjuvant, and peri-operative therapy is allowed, provided it has been completed more than 6 months prior to the first dose of study treatment
  • Fibroblast growth factor receptor 2b (FGFR2b) overexpression positive as determined by centrally performed immunohistochemistry (IHC) testing based on tumor sample either archival (obtained within 6 months/180 days prior to signing pre-screening informed consent) or a fresh biopsy.
Exclusion Criteria
  • Prior treatment with any selective inhibitor of the fibroblast growth factor (FGF)-FGFR pathway
  • Known positive human epidermal growth factor receptor 2 (HER2) status
  • Untreated or symptomatic central nervous system disease metastases and leptomeningeal disease
  • Peripheral sensory neuropathy grade 2 or higher
  • Clinically significant cardiac disease
  • Other malignancy within the last 2 years (exceptions for definitively treated disease)
  • Chronic or systemic ophthalmologic disorders
  • Major surgery or other investigational study within 28 days prior to randomization
  • Palliative radiotherapy within 14 days prior to randomization
  • Abnormalities of the cornea that may pose an increased risk of developing a corneal ulcer
  • Active autoimmune disease that has required systemic treatment (except replacement therapy) within the past 2 years or any other diseases requiring immunosuppressive therapy while on study
