SAN FRANCISCO (MarketWatch) — Roche Holdings Ltd. and Trimeris Inc. late Friday said that new interim results from an ongoing study demonstrate a high response rate with Fuzeon plus darunavir, regardless of existing protease inhibitor resistance. The data showed that about 64% of three-class, treatment-experienced patients achieved undetectable HIV at 24 weeks, and that baseline sensitivity to darunavir didn’t appear to influence patient response to the regimen, the companies said. Fuzeon, co-developed by Roche and Trimeris, is a fusion inhibitor available for the treatment of HIV, while darunavir is a commercially available, ritonavir-boosted protease inhibitor, marketed by Tibotec Therapeutics. The study was presented at the 4th International AIDS Society Conference on HIV Pathogenesis, Treatment and Prevention in Sydney, Australia.Market Pulse Stories are Rapid-fire, short news bursts on stocks and markets as they move.
