Brief Summary

Phase I Study of biweekly combination therapy with S-1, Irinotecan, and Bevacizumab as 1-line Chemotherapy in Patients With Advanced Colorectal Cancer.

Detailed Description

In several clinical studies from Japan and South Korea, the combination regimen of S-1 and irinotecan has shown efficacy in the treatment of advanced colorectal cancer, and a Phase III study(TRICOLORE) showed that the combination therapy with S-1/irinotecan/bevacizumab (a 3-week regimen \[SIRB\] or 4-week regimen \[IRIS/bevacizumab\]) is not inferior to the oxaliplatin-based standard treatment (mFOLFOX6/bevacizumab or CapeOX/bevacizumab) in patients with metastatic colorectal cancer who had not previously received chemotherapy. Here, we design this phase I study to explore the Chinese population's tolerability and efficacy of Biweekly SIRB Regimen(S-1/irinotecan/bevacizumab) and to explore the recommended dose of irinotecan in this regimen.

    • Neutrophil count ≥1,500/mm3

    • Platelet count ≥100,000/mm3

    • AST and ALT ≤100 U/L (<200 U/L in patients with liver metastasis)

    • Serum creatinine ≤1.2 mg/dL

      • Creatinine clearance estimate by the Cockcroft-Gault method >50 mL/min (reduce initial dosage by one step if ≥50 but <80 mL/min)
  • Able to take capsules orally.

  • No electrocardiographic abnormalities within 28 days before enrollment that would clinically preclude the execution of the study, as judged by the investigator.

  • Voluntary written informed consent.

Exclusion Criteria
  • Serious drug hypersensitivity or a history of drug allergy
  • Active double cancer
  • Active infections (e.g., patients with pyrexia of 38℃ or higher)
  • History of gastrointestinal perforation, intestinal tract paralysis, or ileus within 1 year.
  • Uncontrolled hypertension
  • Serious complications (e.g., pulmonary fibrosis, interstitial pneumonitis, heart failure, renal failure, hepatic failure, or poorly controlled diabetes)
  • Moderate or severe ascites or pleural effusion requiring treatment
  • Watery diarrhea
  • Treatment with flucytosine or atazanavir sulfate
  • Metastasis to the CNS
  • Pregnant women, possibly pregnant women, women wishing to become pregnant, and nursing mothers. Men who are currently attempting to conceive children.
  • Severe mental disorder
  • Continuous treatment with steroids
  • Urine dipstick for proteinuria should be <2+
  • Patient with a past history of thrombosis, cerebral infarction, myocardial infarction, or pulmonary embolism
  • Major surgical procedure, open biopsy, or clinically significant traumatic injury within 4 weeks
  • Long-term daily treatment with aspirin (>325 mg/day)
  • History or evidence of inherited bleeding diathesis or coagulopathy with the risk of bleeding
  • Judged ineligible for participation in the study by the investigator for safety reasons.
