A Study of TS-1, Cisplatin (CDDP) and RAD001 (Everolimus)

Inclusion Criteria:

  * bone marrow function (ANC ≥ 1,500/uL, Platelet ≥ 100,000/ uL, Hb ≥ 9.0 g/dl)
  * renal function: serum creatinine ≤ UNL (if serum creatinine \> ULN, creatinine clearance should be ≥ 60 mL/min)
  * hepatic function (Total bilirubin \< 2 x UNL and AST/ALT levels \< 3 x ULN without liver metastasis, total bilirubin \< 3x ULN and AST/ALT levels \< 5 x ULN with liver metastasis)
* Prior systemic therapy (eg, cytotoxic chemotherapy or biologic therapy) and major surgery are allowed if at least 28 days has elapsed between completion of therapy and administration of study drugs
* Ability to understand and willingness to sign a written informed consent before study entry

Exclusion Criteria:

* Failure to recover from the reversible effects of previous chemotherapy, radiotherapy, hormonal, or biologic therapy prior to enrollment
* Second primary malignancy (except in situ carcinoma of the cervix or adequately treated basal cell carcinoma of the skin or prior malignancy treated more than 5 years ago without recurrence)
* Prior radiotherapy was administered to target lesions selected for this study, or radiotherapy to the non-target lesions has been completed within 4 weeks before randomization
* Prior mTOR inhibitor
* Presence of symptomatic or progressing CNS metastasis
* Serious illness or medical conditions:

  * Congestive heart failure (NYHA class III or IV), unstable angina or myocardial infarction within the past 12 months
  * Significant arrhythmias requiring medication and conduction abnormality such as over 2nd degree AV block

Flucytosine (a fluorinated pyrimidine antifungal agent) Antivirals such as sorivudine, ramivudine, brivudine or other chemically related agents, warfarin, phenprocoumon, phenytoin, allopurinol, immunosuppressive agents. Strong and moderate inhibitors or inducers of P-glycoprotein, CYP3A4 and CYP3A5 (appendix A) are not eligible; a minimal of 2 weeks wash- out period will be required after stop such medications
* Known hypersensitivity to TS-1, CDDP or mTOR inhibitor.
* Pregnant or lactating woman. Women of child bearing potential not using a contraceptive method
* Sexually active fertile men not using effective birth control during medication of study drug and up to 6 months after completion of study drug if their partners are women of child-bearing potential
