Arms of the Study
Arm 1
Experimental
OIS (Oxaliplatin, Irinotecan, S-1)
Dose level 1 treatment will be delivered as a 2-week cycle as bellows; Oxaliplatin 85 mg/m²IV on day 1 Irinotecan 120 mg/m² IV on day 1 S-1 60 mg/m2/day PO on day 1-7 Dose escalation will be continued until more than one-third of the patients in a given cohort show dose limiting toxicities (DLT) during treatment cycle 1. If at least 2 patients are observed to have DLT, this dose level is defined as the maximum tolerated dose (MTD). If exactly 1 of the 3 patients treated show DLT, 3 additional patients are treated at the current dose level.
