Results From Multi-Dose Vorinostat Trial
Selected Research Highlight From CROI 2013

By Richard Jefferys

March 25, 2013

Sharon Lewin from Monash University in Melbourne debuted data from the first multidose trial of vorinostat (also known as SAHA) as a potential anti-HIV latency drug (abstract, webcast -- ninth in session). Consistent with results published by David Margolis from a single-dose trial, expression of HIV RNA significantly increased among the twenty participants after 14 days of vorinostat. However, there was no evidence for reduction in the size of the latent HIV reservoir, suggesting that additional approaches will be needed to facilitate the elimination of the infected cells. As expected, vorinostat side effects were more prevalent as a result of the multiple dosing, particularly fatigue and lethargy.
