Sylatron™ receives FDA approval based on the EORTC 18991 trial

28/04/2011

Based on the EORTC 18991 trial, the United States Food and Drug Administration approved Sylatron™, pegylated interferon α-2b, on 29 March 2011 for the treatment of melanoma patients with microscopic or gross nodal involvement within 84 days of definitive surgical resection including complete lymphadenectomy.

The EORTC 18991 trial was an open label, multicenter trial that enrolled 1256 patients. Patients who had been adequately surgically resected for their primary cutaneous melanoma and affected regional lymph nodes were randomized to receive either Sylatron™ or observation for a five year period. Based on 696 relapse-free survival events, an improvement in relapse-free survival for Sylatron™ treated patients [hazard ratio 0.82 (95% CI: 0.71, 0.96); unstratified log-rank p = 0.011] was observed. The estimated median relapse-free survival was 34.8 months (95% CI: 26.1, 47.4) in the Sylatron™ arm and 25.5 months (95% CI: 19.6, 30.8) in the observation arm, respectively. There was no difference in overall survival between the Sylatron™ and the observation arms [hazard ratio 0.98 (95% CI: 0.82, 1.16)].

Clinical results for this study were published by Eggermont et al. 1as were the health-related quality of life and symptoms2.
