Randomized phase II study of nab-paclitaxel as first-line chemotherapy in patients with HER2-negative metastatic breast cancer.

ABSTRACT: Weekly administration of nanoparticle albumin-bound paclitaxel (nab-paclitaxel) has been shown to be a safe and effective treatment for metastatic breast cancer (MBC) in clinical studies. We conducted a multicenter, randomized, open-label phase II study to compare the efficacy and safety of weekly nab-paclitaxel and docetaxel in Japanese patients with human epidermal growth factor receptor 2-negative MBC. The primary endpoint was progression-free survival (PFS). Patients were randomized to receive nab-paclitaxel (150 mg/m² nab-paclitaxel once per week for 3 of 4 weeks; n = 100) or docetaxel (75 mg/m² docetaxel every 3 weeks; n = 100). The median PFS by independent radiologist assessment was 9.8 months (90% confidence interval [CI]: 8.5-11.2) for nab-paclitaxel and 11.
