Active Comparator: 5-FU/cisplatin Drug: Fluorouracil/cisplatin (control arm)

5-FU: 800 mg/m2 BSA/24 hours by continuous intravenous infusion (CIV) from Days 1 through 5 plus cisplatin 80 mg/m2 BSA on Day 1 each 21 day cycle.

Number of Cycles: until progression or unacceptable toxicity develops. Treatment with cisplatin is limited to a maximum of 8 cycles.

Other Name: TS-1, Tegafur/Gimeracil/Oteracil

Detailed Description:

This is an open-label, international, Phase 3 study evaluating the efficacy and safety of the S-1/cisplatin regimen versus the 5-FU/cisplatin regimen in chemotherapy-naïve patients with metastatic diffuse gastric carcinoma including carcinoma of the gastro-esophageal junction. Patients will be randomly assigned to S-1/cisplatin (experimental regimen, Arm A) or 5-FU/cisplatin (control regimen, Arm B).
