This single-arm study assessed the efficacy and safety of first-line treatment with Avastin (bevacizumab) in combination with taxane-based chemotherapy (paclitaxel and gemcitabine) in patients with HER-2 negative breast cancer. Patients received Avastin 10 mg/kg iv, paclitaxel 150 mg/m^2 iv, and gemcitabine 200 mg/m^2 iv on Day 1 and Day 15 of each 4-week treatment cycle until disease progression, death, or withdrawal of consent. The gene discussed is ERBB2; the disease is breast cancer.
