A Study Evaluating the Efficacy and Safety of Bevacizumab in Combination With Chemotherapy in Untreated Metastatic Breast Cancer (RIBBON 1)
Basic Trial Information
|Phase III||Treatment||Closed||18 and over||Pharmaceutical / Industry||AVF3694g|
This is a Phase III, multicenter, randomized, placebo-controlled trial designed to evaluate the efficacy and safety of bevacizumab in combination with chemotherapy compared with chemotherapy alone in subjects with previously untreated metastatic breast cancer.
Further Study Information
This study includes a blinded treatment phase, an optional open-label post-progression phase, and a survival follow-up phase. During the blinded treatment phase, patients receive chemotherapy and study drug (bevacizumab or placebo) every 3 weeks until disease progression, treatment-limiting toxicity, or death due to any cause. The optional open-label post-progression phase consists of chemotherapy treatment (per investigator discretion) and optional treatment with open-label bevacizumab. Patients who complete the study or who discontinue from treatment (regardless of participation in the optional open-label post-progression phase) will be followed for survival and subsequent anti-cancer therapies every 4 months until death, withdrawal of consent, loss to follow-up, or study termination. Patients who discontinue from treatment during the blinded treatment phase for reasons other than disease progression will have tumor assessments every 9 weeks until documented disease progression or death.
