INTRODUCTION: Treatment outcomes in patients with advanced non-small cell lung cancer (NSCLC) are poor due to limited treatment options.
OBJECTIVE: We conducted a multicenter, single-arm phase II study to prospectively assess the efficacy and safety of weekly nab-PTX in patients with advanced NSCLC with failed cytotoxic chemotherapy.
METHODS: Patients with advanced NSCLC having adequate organ functions with a performance status of 0-1 were enrolled. A 100 mg/m2 dose of nab-paclitaxel was administered on days 1, 8, and 15 of a 28-day cycle. Primary endpoint was the objective response rate (ORR). Secondary endpoints were disease control rate (DCR), toxicity profile, progression-free survival (PFS), and overall survival (OS).
RESULTS: Between September 2013 and May 2016, 35 patients were enrolled. The ORR was 31.4%, and the DCR was 74.3%. The median PFS was 3.6 months, and the median OS was 11.4 months. The most common grade 3 or 4 toxicities included neutropenia (54.3%), leukopenia (42.9%), and anemia (11.4%). Two patients discontinued chemotherapy due to pneumonitis.
CONCLUSIONS: Nab-PTX may be a later-line chemotherapeutic option for previously treated advanced NSCLC.
