Mapping Pathways is a multi-national project to develop and nurture a research-driven, community-led global understanding of the emerging evidence base around the adoption of antiretroviral-based prevention strategies to end the HIV/AIDS epidemic. The evidence base is more than results from clinical trials - it must include stakeholder and community perspectives as well.

Questions Surround PrEP Trials

via The New York Times, by David Tuller

In the past year, three landmark clinical trials have shown that a daily dose of the antiretroviral medication Truvada can protect individuals from infection with H.I.V. — a significant discovery, given the failure so far of all efforts to develop a vaccine against the virus.

Now researchers in San Francisco and Miami are planning to test this prevention strategy, called pre-exposure prophylaxis, or PrEP, in a pilot study supported by the National Institutes of Health. The researchers will soon recruit up to 500 uninfected men who have sex with men, especially those considered to be at greatest risk of infection, such as younger gay men and, in particular, African-Americans.

The men will be asked to take Truvada daily, and the researchers will monitor their compliance with the regimen, their sexual behavior and their health status. Already, though, the prospect of antiretroviral drugs’ being used for prevention as well as treatment is raising complex questions for researchers and advocates.

Will healthy uninfected people consistently take an expensive and powerful drug that can cause a range of side effects? Is it fair to provide medications to H.I.V.-negative individuals when so many of those already infected do not have access? Will those receiving the drug be more likely to engage in risky sex because they believe they are protected — even if they do not always take it as prescribed?

Read the rest.
