UK-453,061

UK-453,061 (lersivirine), a Pfizer drug now being developed by ViiV Healthcare, is a second-generation NNRTI. It does not seem to have a significant effect on CYP3A4 metabolic activity and  appears to be active against the common NNRTI mutations. It is enrolling patients into a phase II study comparing UK-453,061 to efavirenz, both taken with Truvada.1
