Title: | Treatment of colorectal cancer with and without bevacizumab: a phase III study. |
Journal: | Oncology |
Year: | 2010 |
PMID: | 20798560 |
Trial Design | |
Clinical Trial Id: | NA |
Agent: | bevacizumab |
Target: | Vascular endothelial growth factor Epidermal growth factor receptor |
Cancer Type: | colorectal cancer |
Cancer Subtype: | advanced colorectal adenocarcinoma |
Therapy Type: | com |
Therapeutic Combination Type: | 2 |
Therapeutic Combination Content: | leucovorin+5fluorouracil+irinotecan+ bevacizumab |
Study Type: | a singlecenterphase III randomized trial. |
Key Patients Feature: | patients with advanced colorectal cancer, all patients were stage IV with histologically confirmed adenocarcinoma |
Biomarker: | NA |
Biomark Analysis: | NA |
Control Group Info: | leucovorin, 5fluorouracil plus irinotecan |
Treatment Info: | treatmentnaive patients were enrolled and divided into 2 arms: 114 arm A patients were treated with leucovorin, 5fluorouracil plus irinotecan in combination with bevacizumab, and 108 arm B patients were treated as above without bevacizumab |
Primary End Point: | The primary objective of the study was to determine survival |
Secondary End Point: | the response rate and toxicity. |
Patients Number: | 222 |
Trial Results | |
DLT_MTD: | NA |
Objective Response Rate: | No statistically significant difference between the 2 arms regarding the response rate was observed: partial response, 42 patients (36.8%) and 38 patients (35.2%) for arms A and B, respectively. |
Disease Control Rate: | NA |
Median Time to Progression: | NA |
Median PFS A vs. C: | NA |
Median OS A vs. C: | 22.0 ms (95% CI: 18.125.9) vs 25.0 ms (CI: 18.131.9), there was no statistically significant difference between the 2 arms (p = 0.1391). |
Adverse Event(agent arm): | Hematologic toxicity did not differ in the comparison of the 2 arms. Nonhematologic toxicity in arm A involved hypertension in 23 (20.2%) of the patients and proteinuria in 7 (6.1%); 3 patients experienced hemorrhage and 1 patient intestinal perforation. None of these side effects was observed in arm B patients. |
Conclusions: | No statistically significant difference in median overall survival in patients with advanced colorectal cancer treated with bevacizumab plus a combination therapy (arm A) and those treated with the combination only, without bevacizumab (arm B), was observed. |
