Abstract
BACKGROUND: This randomized, double-blind, phase 2 trial evaluated whether the addition of vandetanib to platinum plus etoposide for previously untreated extensive-stage small cell lung cancer (SCLC) prolonged the time to disease progression in comparison with chemotherapy alone. METHODS: Patients with previously untreated extensive-stage SCLC received platinum (cisplatin or carboplatin) with etoposide in combination with vandetanib (100 mg daily) or a placebo for up to 4 total cycles (no maintenance therapy). An initial safety run-in phase was conducted with the first 6 patients enrolled; all these patients received vandetanib with cisplatin and etoposide. With an overall sample size of 68 patients, the study had 80% power to detect a 3-month difference in the time to progression (TTP) from 4 to 7 months (significance level,.10 [1-sided log-rank test]). RESULTS: Seventy-four patients were enrolled between April 2008 and May 2013. Thirty-three patients were ultimately randomized to each arm. The baseline characteristics were well balanced, and the median number of treatment cycles was 4 for each arm. Thirty-one patients in each arm were evaluable for TTP; the median TTP was 5.62 months with vandetanib and 5.68 months with the placebo (P = .9518). The median overall survival was 13.24 months with vandetanib and 9.23 months with the placebo (P = .4577; 33 evaluable patients in each arm). Nonhematologic toxicity was increased with vandetanib versus the placebo. No correlation was seen between vascular endothelial growth factor polymorphisms and outcomes. CONCLUSIONS: The addition of vandetanib to platinum and etoposide did not improve outcomes for patients with newly diagnosed extensive-stage SCLC. Toxicity was increased in comparison with chemotherapy alone. Cancer 2017;123:303-311.
