Primary Outcome Measures:
  • In phase II part, progressive disease rate will be measured for the safety. In phase III part, overall survival will be measured for the benefit of doublet. [ Time Frame: Phase II: 6 weeks from treatment, Phase III: 2 years OS from randomization ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Adverse events, response rates, progression free survival, time to treatment failure, change over rates to 3rd line [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]

Detailed Description:

Standard chemotherapy for advanced gastric cancer (AGC) in the US is Cisplatin/5-FU (CF) or docetaxel/CF (DCF), is in Europe epirubicin/CF (ECF) or epirubicin/oxaliplatin/ capecitabine (EOX). Until 2006, there was no evidence of standard chemotherapy for AGC in Japan. In 2007, by the results of JCOG9912 trial (5-FU alone vs. CPT-11/CDDP vs S-1) and SPIRITS trial (S-1 alone vs. S-1/CDDP), S-1/CDDP is regarded as a new standard regimen in Japan. In 2008, by the results of TOP-002 trial (s-1 alone vs. S-1/CPT-11), S-1/CPT-11 could not show the superiority to S-1 alone. One of the other phase III trials, JACCRO GC-03 trial (S-1 alone vs. S-1/docetaxel, NCT00287768) is now ongoing. However, the position of CPT-11 in the treatment of AGC will be regarded as a second-line.

In Japan there is a controversy for the treatment of S-1 refractory gastric cancer. The controversy is continuing S-1 (like FOLFOX to FOLFIRI) or not as a second-line. After the successful adjuvant S-1 results (ACTS-GC trial), the same problem will occur in the patients who are recurrent from adjuvant S-1.

Then, we conducted a phase II/III trial of CPT-11 with or without S-1 in the treatment of first-line S-1 refractory AGC.
