Eligibility criteria:

        Inclusion Criteria:

        A patient must meet all of the following inclusion criteria to be eligible for enrollment
        in this study:

          -  Has given written informed consent

          -  Has histologically confirmed, unresectable, locally advanced (Stage IV) or metastatic
             gastric cancer, including adenocarcinoma of the gastro-esophageal junction

          -  Has measurable or evaluable but non-measurable disease, defined as follows:

               -  Measurable Disease - Patients with measurable disease as defined by RECIST
                  criteria, i.e., the presence of at least one measurable lesion. A measurable
                  lesion is one that can be accurately measured in at least one dimension with the
                  longest diameter >_ 20 mm using conventional techniques or >_ 10 mm using spiral
                  Computed Tomography (CT)scan. Locally recurrent disease (other than primary) is
                  accepted if there is at least one measurable lesion (i.e. peritoneal mass, lymph
                  node, etc.)

               -  Evaluable but Non-measurable Disease - Patients with all lesions below the limits
                  defined above for measureable disease (i.e., longest diameter < 20 mm with
                  conventional techniques or < 10 mm with spiral CT) excluding those patients with
                  only a primary lesion and/or with only non-evaluable cancer such as bone
                  metastases, ascites, pleural or pericardia effusions, lymphangitic carcinomatosis
                  of the skin or lung, previously irradiated lesions not in progression, or
                  peritoneal carcinomatosis < 10 mm in diameter with conventional imaging
                  techniques.

          -  No prior palliative chemotherapy is permitted. Adjuvant and /or neo-adjuvant
             chemotherapy is permitted if more than 12 months have elapsed between the end of
             adjuvant or neo-adjuvant therapy and first recurrence. This does not qualify as 1st
             line therapy.

          -  Is able to take medications orally

          -  Is >_ 18 years of age

          -  Has adequate organ function as defined by the following criteria:

               -  AST (SGOT) and ALT (SGPT) <_ 2.5 x ULN; if liver function abnormalities are due
                  to underlying liver metastasis, AST (SGOT) and ALT (SGPT) <_ 5 x ULN

               -  Total serum bilirubin of <_ 1.5 x ULN

               -  Absolute granulocyte count of >_ 1,500/mm (i.e. >_ 1.5 x 10/L by International
                  Units (IU)

               -  Platelet count >_ 100,000/mm (IU: >_ 100 x 10/L

               -  Hemoglobin value of >_ 9.0 g/dL

               -  Calculated creatinine clearance >_ 60 mL/min (Cockcroft-Gault formula)

          -  Is willing and able to comply with scheduled visits, treatment plans, laboratory tests
             and other study procedures

        Exclusion Criteria:

                  results, and in the judgement of the Investigator would make the patient

                  activity)

               -  Allopurinol (may diminish S-1 activity

               -  Phenytoin (S-1 may enhance phenytoin activity)

               -  Flucytosine, a fluorinated pyrimidine antifungal agent (may enhance S-1 activity)

          -  Is receiving concomitant treatment with drugs interacting with 5-FU:
