简要总结
This randomized, open-label, multicenter study will evaluate the efficacy and safety of folinic acid (leucovorin), 5-fluorouracil (5-FU), oxaliplatin, and irinotecan (FOLFOXIRI) / bevacizumab regimens (concurrent and sequential) versus folinic acid (leucovorin), 5-fluorouracil, and oxaliplatin (FOLFOX) / bevacizumab in first-line in participants with metastatic colorectal cancer. Participants will be randomized to receive bevacizumab 5 milligrams per kilogram (mg/kg) intravenously every 2 weeks with either concurrent or sequential FOLFOXIRI or with FOLFOX for 4 to 6 months of induction therapy, followed by maintenance therapy with bevacizumab plus either leucovorin/5-fluorouracil or capecitabine until disease progression occurs. After disease progression, participants will receive treatment with a fluoropyrimidine-based chemotherapy plus bevacizumab.

结局指标
主要结局
Percentage of Participants With Overall Response During First-Line Therapy (ORR1)
时间窗: Randomization up to disease progression during first-line therapy or death, whichever occurs first (up to approximately 3 years)
ORR1 was the percentage of participants with complete response (CR) or partial response (PR) during first-line therapy as assessed by investigator according to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v.1.1). CR was defined as disappearance of all extranodal target lesions and all pathological lymph nodes had to have decreased to \<10 millimeter (mm) in short axis. PR was defined as at least a 30% decrease in the sum of longest diameters of target lesions, taking as reference the baseline sum diameters. ORR1 = CR + PR
Progression-Free Survival During First-Line Therapy (PFS1)
时间窗: Randomization up to disease progression during first-line therapy or death, whichever occurs first (up to approximately 3 years)
PFS1 was defined as time from randomization to the first occurrence of disease progression during first-line therapy, as assessed by the Investigator using RECIST v1.1, or death from any cause, whichever occurs first. Disease progression was defined as sum of longest diameters increased by at least 20% from the smallest value on study. The sum of longest diameters must also demonstrate an absolute increase of at least 5 mm.
次要结局
- Time to PFS2(Randomization up to disease progression during second-line therapy or death, whichever occurs first (up to approximately 3 years))
- Overall Survival (OS)(Randomization until death due to any cause (up to approximately 3 years))
- Proportion of Participants Who Underwent Liver Metastases Resections(Randomization up to approximately 3 years)
- Proportion of Participants Considered by the Investigator to be Unresectable on Study Enrollment Who Subsequently Underwent Attempted Curative Resections of Metastases(Randomization up to approximately 3 years)
- Percentage of Participants With Adverse Events(Randomization up to approximately 3 years)
