INTRODUCTION: This nonrandomized study aimed to identify the optimal dose of every-3-week (q3w) and weekly nab-paclitaxel plus q3w carboplatin as first-line therapy in patients with advanced non-small cell lung cancer (NSCLC) for a phase 3 trial. METHODS:Previously untreated patients with advanced NSCLC enrolled sequentially into seven cohorts (25 patients/cohort, N = 175). Cohorts 1 to 4 and 5 to 7 received nab-paclitaxel q3w and weekly, respectively. Patients were evaluated for efficacy and safety. RESULTS: The most common treatment-related > or = grade 3 adverse events were neutropenia (60%), neuropathy (19%), fatigue (9%), and thrombocytopenia (29%) (no grade 4 neuropathy or fatigue). A 100 mg/m(2) weekly nab-paclitaxel produced less serious adverse events than other doses/schedules. Response rate (RR) was greater in the weekly versus q3w cohorts (47% vs. 30%). Median progression-free survival (PFS) ranged from 4.8 to 6.9 months, and overall survival (OS) ranged from 8.3 to 15.0 months (all cohorts). Patients receiving 100 mg/m(2) weekly nab-paclitaxel achieved 48% RR with 6.2 and 11.3 months of PFS and OS, respectively. In a retrospective analysis, patients with nonsquamous cell carcinoma receiving weeklynab-paclitaxel had significantly improved RR (59.4% vs. 23.5%, respectively, p = 0.003), and >2 months longer PFS and OS compared with q3w schedule. In patients with squamous cell carcinoma, the q3w schedule significantly increased PFS by 3 months (p = 0.014) and OS by >2 months (no difference in RR) compared with the weekly schedule. CONCLUSION:nab-Paclitaxel plus carboplatin is an effective therapy for advanced NSCLC. Based on favorable efficacy and safety profiles, a phase 3, randomized, multicenter study comparing 100 mg/m(2) weekly nab-paclitaxel plus q3w carboplatin to solvent-based paclitaxel plus carboplatin has enrolled patients.
