A phase II study of nintedanib in patients with relapsed small cell lung cancer

Nintedanib is an oral triple angiokinase inhibitor. This study was conducted to evaluate the efficacy and safety of nintedanib in patients (pts) with relapsed/refractory small cell lung cancer (SCLC). Patients and methods Pts with an ECOG PS from 0 to 2 who exhibited progression after one or two prior chemotherapy or chemo/radiotherapy were enrolled. Pts received nintedanib 200mg BID daily in a 4-week cycle until progression or intolerable toxicity. The primary end point was the objective response rate (ORR). A two-stage design was employed. To continue to stage 2, ≥2 responders out of 22 pts were required. Results From Dec 2011 to June 2014, 24 pts were enrolled. Twenty-two pts completed treatment and were evaluable for response. The median follow-up was 9.7 (0.5–19.8) months. The median age was 64 (46–77) years. Twenty-two pts were male. Six pts had sensitive relapse. Eight pts received one prior chemotherapy. A median of one (range 1–5) cycle was administered. One pt had a partial response, and seven pts exhibited stable disease. The ORR was 5% (95% confidence interval [CI], 0.1–22.8). Median progression-free survival was 1.0 (95% CI, 0.9–1.1) month, and overall survival was 9.8 (95% CI, 8.4–11.2) months. The response criteria to proceed to full accrual were not met. The most frequent drug-related adverse events (AE) included hepatic enzyme elevation (86%), anemia (73%), anorexia (59%), and nausea (50%). Most AEs were mild and manageable. Grade 3 hepatic enzyme elevation occurred in 5 pts (23%). Conclusions Nintedanib exhibited only limited activity with a manageable AE profile in relapsed or refractory SCLC (NCT01441297).
