Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open-Label, Multicenter, Randomized, Phase 3 Study of S-1 and Cisplatin Compared With 5-FU and Cisplatin in Patients With Metastatic Diffuse Gastric Cancer Previously Untreated With Chemotherapy

Primary Outcome Measures:
  • Outcome Measure: Overall survival (OS) [ Time Frame: 12 months after the last patient is randomized or the target number of events is reached, whichever is later ]

Secondary Outcome Measures:
  • Progression-free survival (PFS) [ Time Frame: Throughout ]
  • Time to treatment failure (TTF) [ Time Frame: Throughout ]
  • Antitumor activity: Overall Response Rate (ORR), duration of response (DR), time to tumor response (TTR); [ Time Frame: Throughout ]
  • Safety and tolerability [ Time Frame: Treatment period ]

Study Start Date: February 2011
Estimated Study Completion Date: May 2017
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)

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