A Monthly HIV Preventive?

More news from the conference in Seattle.
The first trial in humans of an injectable, once-a-month formulation of an HIV drug has found that drug levels were maintained at a level that should in theory be high enough to protect recipients against infection, and that the drug has so far produced very few side effects. The research was presented at the 19th Conference on Opportunistic Infections (CROI), in Seattle. The small trial at the St Stephen’s AIDS Trust (SSAT) at London’s Chelsea and Westminster Hospital gave 27 women and six men a single injection of the long-acting formulation of the drug rilpivirine, which was licensed as an oral HIV treatment last year as Edurant and is also in the tenofovir/FTC/rilpivirine pill Complera. Rilpivirine is a non-nucleoside reverse transcriptase inhibitor (NNRTI) drug and is especially suitable to be turned into a long-lasting injectable form because the daily dose of it required to suppress HIV is very small.
