Clinical Trial Summary

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

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.

• 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.

• 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

• 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

Intervention

Drug:
• S-1
- S-1 is administered orally on days 1 to 7 of a 14-day cycle. Patients are assigned on the basis of body surface area (BSA) to receive one of the following oral doses twice daily: 40 mg (BSA <1.25m2), 50 mg (BSA >1.25 to <1.50 m2), or 60 mg (BSA >1.50 m2).
• Irinotecan
- CPT-11 was administrated as a 90-min intravenous infusion on day 1 of a 14-day cycle. Five escalating dose levels of CPT-11 were prepared, at an initial dose of 75mg/m2/day (level 1), stepping up to 100 (level 2), 125 (level 3), 150 (level 4) or 175 (level 5) mg/m2/day.
• Bevacizumab
- Bevacizumab (5 mg/kg) is administered by intravenous infusion over the course of 30 to 90 min on day 1 of each 2-week cycle.
