简要总结
Phase I Study of biweekly combination therapy with S-1, Irinotecan, and Bevacizumab as 1-line Chemotherapy in Patients With Advanced Colorectal Cancer.
详细描述
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.
排除标准
- •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

- •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)
