Résumé
Background: The objective of this multicenter, prospective uncontrolled phase II trial was to determine efficacy, safety and tolerability of vatalanib, an oral angiogenesis inhibitor targeting all known vascular endothelial growth factor receptors, in the second-line treatment of non-small-cell lung cancer (NSCLC). Patients and methods: Patients with stage IIIB/IV NSCLC-proven tumor progression during or after one platinum-based chemotherapy regimen received a fixed dose of 1250 mg vatalanib either once-daily dosing (QD) or two divided daily dosing (TDD: 500 mg a.m. + 750 mg p.m.) until disease progression or unacceptable toxicity. Primary end point was the disease control rate (DCR) at 12 weeks. Results: Fifty-four and 58 patients were enrolled to the QD and TDD arms. DCR at 12 weeks was 35% in the QD and 37% in the TDD arm. The best overall response included one (2%) patient with confirmed partial response with QD and three (5%) with TDD. Median progression-free survival and overall survival were 2.1/7.3 months in the QD arm and 2.8/9.0 months with TDD arm. This therapy showed a moderate toxicity profile for the majority of patients. Conclusions: In the chosen patient population, vatalanib QD and TDD dosing demonstrated potential benefits in tumor size reduction, DCR, and survival.
