Eligibility criteria:

        Inclusion Criteria:

          -  Patients must have pathologically or cytologically MSKCC confirmed diagnosis of
             gastric or GEJ adenocarcinoma.

          -  Patients must have Stage IV gastric or GEJ adenocarcinoma with HER2 overexpression
             and/or amplification as determined by next generation sequencing assay,
             immunohistochemistry (IHC 3+) or fluorescent in situ hybridization (FISH+ is defined
             as HER2:CEP17 ratio ≥ 2.0). MSKCC confirmation of HER2 status is not mandatory prior
             to enrollment and treatment on study. For patients with outside HER2 testing, if
             sufficient tissue is available HER2 testing will be repeated at MSKCC for purpose of
             analysis and will not impact the patient's eligibility.

          -  Available archival tumor tissue should be submitted to MSKCC for IMPACT analysis, but
             will not be required prior to registration. Note: if tissue is depleted, patient will
             still be eligible after discussion with the PI.
