ScienceDaily (July 18, 2012) — Scientists are launching the first clinical trial to test whether drug regimens containing maraviroc, a medication currently approved to treat HIV infection, are also safe and tolerable when taken once daily by HIV-uninfected individuals at increased risk for acquiring HIV infection. The eventual goal is to see if the drug regimens can reduce the risk of infection

The trial involves a strategy known as pre-exposure prophylaxis, or PrEP, in which HIV-uninfected individuals who are at risk for contracting the virus take one or two HIV drugs routinely in an effort to prevent infection. Called Novel Exploration of Therapeutics for PrEP, or NEXT-PrEP, the two-year study is sponsored and funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.

"The NEXT-PrEP study will examine whether maraviroc-based PrEP is safe and well-tolerated. It is a necessary first step before we can test the effectiveness of maraviroc-based PrEP, and in the future, potentially expand the selection of drugs that may be used in this emerging HIV prevention strategy," said NIAID Director Anthony S. Fauci, M.D.

Led by principal investigator Roy M. Gulick, M.D., M.P.H., chief of the Division of Infectious Diseases and professor of medicine at Weill Cornell Medical College of Cornell University, the study team will enroll 400 HIV-uninfected men who have sex with men (MSM) ages 18 and older in 12 cities in the United States and Puerto Rico. The volunteers will be assigned at random to take one of the following four PrEP study regimens daily for 48 weeks:

Maraviroc (300 milligrams)
Maraviroc (300 milligrams) plus emtricitabine (200 milligrams)
Maraviroc (300 milligrams) plus tenofovir disoproxil fumarate (300 milligrams)
Emtricitabine (200 milligrams) plus tenofovir disoproxil fumarate (300 milligrams)

1. Good. As a nurse who got speared more than once at the height

of the mid 80s slaughter before much of anything was available, I applaud anything that would prevent this monster of a disease.

The only problem will be getting it to the people who need it, usually people who do their best to stay off the government's radar.
