| Abstract: | Background.Platinum plus etoposide is the standard therapy for extensive-stage small cell lung cancer (ES-SCLC) and is associated with significant myelosuppression. We hypothesized that the combination of carboplatin and nanoparticle albumin-bound paclitaxel (nab-paclitaxel) would be better tolerated. We investigated carboplatin with nab-paclitaxel on every-3-week and weekly schedules.Methods.This noncomparative randomized phase II trial used a two-stage design. The primary objective was objective response rate, and secondary objectives were progression-free survival, overall survival, and toxicity. Patients with ES-SCLC and an Eastern Cooperative Oncology Group performance status ≤2 and no prior chemotherapy were randomized in a 1:1 ratio to arm A (carboplatin area under the curve [AUC] of 6 on day 1 and nab-paclitaxel of 300 mg/m2 on day 1 every 3 weeks) or arm B (carboplatin AUC of 6 on day 1 and nab-paclitaxel 100 mg/m2 on days 1, 8, and 15 every 21 days). Response was assessed after every two cycles.Results.Patients required frequent dose reductions, treatment delays, and omission of the weekly therapy. The trial was closed because of slow accrual.Conclusion.Carboplatin and nab-paclitaxel demonstrated activity in ES-SCLC but required frequent dose adjustments. |
