Clinical Trial Id: | NA |
Agent: | bevacizumab |
Target: | Vascular endothelial growth factor Epidermal growth factor receptor |
Cancer Type: | colorectal cancer |
Cancer Subtype: | advanced colorectal carcinoma, with bidimensionally measurable disease. |
Therapy Type: | com |
Therapeutic Combination Type: | 2 |
Therapeutic Combination Content: | irinotecan, bolus fluorouracil+leucovorin (IFL)+bevacizumab |
Study Type: | a phase III trial |
Key Patients Feature: | patients with previously untreated metastatic colorectal cancer |
Biomarker: | NA |
Biomark Analysis: | NA |
Control Group Info: | IFL plus placebo |
Treatment Info: | randomly assigned 402 to receive irinotecan, bolus fluorouracil, and leucovorin (IFL) plus bevacizumab (5 mg per kilogram of body weight every two weeks) and 411 to receive IFL plus placebo. |
Primary End Point: | overall survival. |
Secondary End Point: | progression free survival, the response rate, the duration of the response, safety, and the quality of life. |
Patients Number: | 813 |
Trial Results | |
DLT_MTD: | NA |
Objective Response Rate: | the corresponding rates of response were 44.8 percent and 34.8 percent (P=0.004). |
Disease Control Rate: | NA |
Median Time to Progression: | NA |
Median PFS A vs. C: | 10.6 months in the group given IFL plus bevacizumab, as compared with 6.2 months in the group given IFL plus placebo (hazard ratio for disease progression, 0.54; P<0.001); |
Median OS A vs. C: | 20.3 ms in the group given IFL plus bevacizumab, as compared with 15.6 ms in the group given IFL plus placebo, corresponding to a hazard ratio for death of 0.66 (P<0.001). |
Adverse Event(agent arm): | Grade 3 hypertension was more common during treatment with IFL plus bevacizumab than with IFL plus placebo (11.0 percent vs. 2.3 percent) but was easily managed |
Conclusions: | The addition of bevacizumab to fluorouracilbased combination chemotherapy results in statistically significant and clinically meaningful improvement in survival among patients with metastatic colorectal cancer. |
