A Study of Bevacizumab (Avastin) in Combination With Chemotherapy in Participants With Metastatic Cancer of the Colon or Rectum.

Phase 3
Completed
Conditions
Colorectal Cancer
Interventions
Drug: Bevacizumab
Drug: Fluoropyrimidine-based Chemotherapy
Registration Number
NCT01169558
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This expanded access study will assess the safety and efficacy of intravenous bevacizumab (5 mg/kg every 2 weeks or 7.5 mg/kg every 3 weeks) in combination with fluoropyrimidine-based chemotherapy as first line treatment in participants with metastatic cancer of the colon or rectum. The anticipated time on study treatment is 3-12 months.

Primary Outcome Measures
NameTimeMethod
Safety: Number of Participants With Serious and Specific Adverse EventsUp to approximately 3 years

A serious adverse event was defined as any experience that suggested a significant hazard, contraindication, side effect, or precaution, and fulfilled any of the following criteria: fatal (resulted in death), life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, was medically significant or required intervention to prevent any of the other outcomes listed here. Specific adverse events (Spec AEs) included the following: hypertension, bleeding/hemorrhage, proteinuria, wound healing complications, thrombosis/thrombus/embolism (t/t/e), thrombosis/thrombus/embolism - vascular access, gastrointestinal perforation, and infusion (injection) site reaction.

Secondary Outcome Measures
NameTimeMethod
Efficacy: Overall SurvivalUp to approximately 3 years

Overall survival was measured as the time from start of first bevacizumab administration to death. For participants who were alive at the end of the study, data on survival were censored at the time of the last contact. Reported is the median duration of overall survival.

Efficacy: Progression-free SurvivalUp to approximately 3 years

Progression-free survival (PFS) was measured as the time from start of first bevacizumab administration to investigator-assessed progression or death, whichever occurred first. Progression was defined using RECIST v1.0, as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions. Reported is the median time of PFS.

Efficacy: Time to Disease ProgressionUp to approximately 3 years

Time to disease progression was measured as the time from start of first bevacizumab administration to investigator-assessed progression. Progression was defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions. For participants without disease progression at the end of the study, date and time to progression were censored at the last investigator assessment. Reported is the median time to disease progression.
