The efficacy and safety of combining bevacizumab (7.5 and 15 mg/kg) with docetaxel as first-line therapy for human epidermal growth factor receptor 2 (HER2) -negative, locally recurrent or metastatic breast cancer (MBC) was investigated in a three-arm, placebo-controlled, phase III trial.


Patients (N = 736) were randomly assigned to docetaxel 100 mg/m(2) plus either placebo or bevacizumab 7.5 or 15 mg/kg every 3 weeks. The primary end point was progression-free survival (PFS); secondary end points included best overall response, duration of response, time to treatment failure, overall survival, and safety.


Combination of bevacizumab 15 mg/kg, but not 7.5 mg/kg, with docetaxel showed superior median PFS (mPFS) to placebo plus docetaxel in unstratified analysis (placebo mPFS, 8.2 months; 7.5 mg/kg mPFS, 9.0 months [hazard ratio (HR), 0.86; P = .12]; 15 mg/kg mPFS, 10.1 months [HR, 0.77; P = .006]) and stratified analysis (placebo mPFS, 8.1 months; 7.5 mg/kg mPFS, 9.0 months [HR, 0.80; P = .045]; 15 mg/kg mPFS, 10.0 months [HR, 0.67; P < .001]). Response rates in patients with measurable disease at baseline also increased with bevacizumab 15 mg/kg (46% [placebo] v 55% [7.5 mg/kg; P = .07] and 64% [15 mg/kg; P < .001]). Combination with bevacizumab had limited impact on the known toxicity profile of docetaxel.


Combination of bevacizumab with docetaxel did not significantly impact on the safety profile of docetaxel. Bevacizumab 15 mg/kg every 3 weeks significantly increased PFS when combined with docetaxel as first-line therapy for MBC compared with docetaxel plus placebo.
