Abstract

Micro-Abstract

We investigated the novel combination of dose-dense pemetrexed, gemcitabine and bevacizumab as frontline treatment for advanced non–small cell lung cancer. Thirty-nine patients received pemetrexed (400 mg/m2), gemcitabine (1200 mg/m2), and bevacizumab (10 mg/kg), given every 14 days. Median progression-free survival was 6.1 months (95% confidence interval [CI], 4.2-7.9) and median overall survival was 18.4 months (95% CI, 13.1-29.5). Treatment met the primary endpoint and represents a reasonable therapeutic option.

Introduction:

Platinum-based chemotherapy is standard for untreated, advanced non-small-cell lung cancer (NSCLC). We investigated the activity and tolerability of the novel combination of dose-dense pemetrexed, gemcitabine, and bevacizumab in patients with advanced NSCLC.

Methods:

This multicenter phase II trial evaluated the safety and efficacy of the combination of pemetrexed (400 mg/m2), gemcitabine (1200 mg/m2), and bevacizumab (10 mg/kg), given every 14 days in patients with untreated, advanced NSCLC. The primary endpoint was progression-free survival with secondary endpoints of response rate and overall survival.

Results:

Thirty-nine patients were enrolled. Treatment was well tolerated; the most common grade 3-4 toxicities were neutropenia and fatigue. Of the 38 patients evaluable for tumor response, 1 (3%) had complete response, 15 (39%) had partial response, 12 (31%) had stable disease, and 10 (26%) had progressive disease. Median progression-free survival was 6.1 months (95% confidence interval [CI], 4.2-7.9) and median overall survival was 18.4 months (95% CI, 13.1-29.5). The 1-year overall survival rate was 64% (95% CI, 51%-81%) and the 2-year overall survival rate was 41% (95% CI, 28%-60%).

Conclusions:

Treatment with dose-dense pemetrexed, gemcitabine, and bevacizumab met the primary endpoint with promising efficacy and a manageable safety profile in patients with untreated advanced NSCLC. This regimen represents a reasonable therapeutic option.
