New HIV PrEP Studies Will Be a Challenge, Statisticians Warn

Two statisticians involved in the PROUD and iPrEx trials of HIV pre-exposure prophylaxis (PrEP) warn that future trials to test new PrEP drugs and formulations may be extremely difficult to design. David Dunn of the UK Medical Research Council and David Glidden of the University of California at San Francisco say that statisticians will need to choose and analyze their trial populations very carefully if they wish to be able to demonstrate meaningful results.

PrEP Plus Increased Testing and Treatment Could Halve HIV Infections Among UK Gay Men

A new British mathematical modeling study published in The Lancet HIV has found that adding pre-exposure prophylaxis (PrEP) for gay men in the U.K. at high risk of HIV to relatively modest increases in HIV testing and immediate treatment for those diagnosed could substantially cut the number of gay men infected by 2020.alt

2 Cases of PrEP Failure on Solo Tenofovir Pose Research Questions

A report originally presented to the 2015 British HIV Association conference last year details 2 cases where therapeutic levels of tenofovir used alone for hepatitis B treatment unequivocally failed to prevent HIV infection in gay men. In one case, despite the tenofovir apparently suppressing the man’s HIV viral load in his blood plasma, it failed to prevent HIV infecting the cells of his immune system.

Model Suggests HIV Vaccine Could Play Key Role in Ending AIDS

Even a modestly effective HIV vaccine would likely be cost-effective and could make a major contribution to a sustainable response to the global HIV/AIDS epidemic, especially in combination with the scale-up of other interventions including prompt antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP), according to a report in the January 5 edition of PLoS ONE.
