DURHAM, N.C. – The HIV Prevention Trials Network (HPTN) today announced the initiation of HPTN 084, a Phase 3 double-blind safety and efficacy study of long-acting injectable cabotegravir (CAB) compared to a combination of daily oral tenofovir disoproxil fumarate 300 mg plus emtricitabine 200 mg (TDF/FTC).

DURHAM, N.C. – Study results released today by the HIV Prevention Trials Network (HPTN) show long-acting injectable cabotegravir (CAB LA) to be well tolerated by men and women and support the dosing schedule currently being used in a phase 3 HPTN study for HIV prevention. Analysis of HPTN 077 study data presented today at the 9th IAS Conference on HIV Science in Paris, France, supported further development of CAB LA for HIV prevention in men and women using 600mg (3 mL) injections every eight weeks with the first two injections given four weeks apart.

DURHAM, N.C. - The HPTN 065 study, conducted by the HIV Prevention Trials Network (HPTN), showed that financial incentives can motivate some people living with HIV (PLWH) to take their HIV antiretroviral therapy (ART) medication regularly and maintain viral load suppression. This finding could have implications for improving health outcomes and decreasing the risk of transmitting the virus to others. Study findings were published today in JAMA Internal Medicine.

DURHAM, N.C. – The HIV Prevention Trials Network (HPTN) has launched a new study, HPTN 083, to evaluate whether injectable cabotegravir (CAB) can safely protect men who have sex with men (MSM) and transgender women (TGW) who have sex with men from acquiring HIV as well as daily oral tenofovir disoproxil fumarate/emtricitabine (TDF/FTC). If found to be safe and effective for HIV pre-exposure prophylaxis, also known as PrEP, injectable CAB may be easier for some people to adhere to than daily oral TDF/FTC.

The HIV Prevention Trials Network (HPTN) commends the participants and researchers on successful completion of the ANRS 12249 TasP (Treatment as Prevention) Study.  The study was conducted in a rural area of northern KwaZulu-Natal (South Africa) where HIV incidence was compared between communities randomized to either immediate offer of antiretroviral therapy (ART) for all individuals diagnosed with HIV, or standard of care ART initiation.  Both study arms included home-based HIV testing.  

DURBAN, South Africa and DURHAM, N.C. – Investigators from the HIV Prevention Trials Network (HPTN) today announced key results from the HPTN 073 Study at the International AIDS Conference (AIDS 2016) in Durban, South Africa. The study, which assessed uptake and adherence of oral pre-exposure prophylaxis (PrEP) for the prevention of HIV infection among Black men who have sex with men (BMSM) in the U.S., demonstrated consistency between self-report and biological markers of adherence.

DURHAM, N.C. – The HIV Prevention Trials Network (HPTN) announced today that the final results of the HPTN 052 study were published in the New England Journal of Medicine (NEJM). This pivotal study demonstrated that antiretroviral therapy (ART) for HIV infection provides durable and reliable protection against the sexual transmission of the virus from infected men and women to their HIV-uninfected sexual partners.

First Study to Evaluate Efficacy of Broadly Neutralizing Monoclonal Antibody in Reducing Acquisition of HIV-1 Infection Among At Risk Populations

BOSTON and DURHAM, N.C. – Investigators from the HIV Prevention Trials Network (HPTN) today announced key results from the HPTN 073 Study at the 2016 Conference on Retroviruses and Opportunistic Infections (CROI) in Boston, Massachusetts. The study showed high uptake of pre-exposure prophylaxis (PrEP) for prevention of HIV infection among Black men who have sex with men (BMSM) in the U.S. with the use of a novel coordinated counseling and care approach resulting in findings suggestive of a lower rate of HIV infection. 

VANCOUVER, B.C. and DURHAM, N.C. - A Phase III, individually randomized trial has found conditional cash transfers for school attendance did not reduce the risk of HIV among high-school aged women in South Africa, investigators from the HIV Prevention Trials Network (HPTN) reported today at the 8th International AIDS Society (IAS) Conference on HIV Pathogenesis, Treatment and Prevention in Vancouver, Canada.

VANCOUVER, B.C. and DURHAM, N.C. - Antiretroviral therapy (ART) for HIV infection provides lasting protection against the sexual transmission of the virus from infected men and women to their HIV-uninfected sexual partners, investigators from the HIV Prevention Trials Network (HPTN) reported today at the 8th International AIDS Society (IAS) Conference on HIV Pathogenesis, Treatment and Prevention in Vancouver, Canada.

VANCOUVER, B.C. and DURHAM, N.C. - Results from HPTN 067, a Phase II, randomized, open-label study, demonstrate most study participants had higher coverage of sex events and better adherence when they were assigned to the daily dosing arm, investigators from the HIV Prevention Trials Network (HPTN) reported today at the 8th International AIDS Society (IAS) Conference on HIV Pathogenesis, Treatment and Prevention in Vancouver, Canada.

The HIV Prevention Trials Network (HPTN) has launched two new phase 2 studies, HPTN 076 and HPTN 077, which are designed to evaluate new drugs to protect people from getting infected with HIV.

HPTN 076 and HPTN 077 are among the first studies to test long-acting, injectable antiretroviral drugs in persons without HIV infection. Antiretroviral drugs are commonly used now as treatment in individuals with HIV infection.

Study results presented today at the Conference on Retroviruses and Opportunistic Infections by the HIV Prevention Trials Network (HPTN) and the National Institutes of Health (NIH) show that a series of community efforts can increase the number of people who get tested and know their HIV status, especially among men and young people with HIV who might otherwise transmit the virus to others. The study was also able to demonstrate a modest 14% reduction in new HIV infections in the intervention communities compared to the control communities.

When the HIV Prevention Trials Network (HPTN) 052 investigators released their landmark study results last year showing that treatment can reduce HIV transmission by 96% in serodiscordant couples, questions were raised about the cost of early antiretroviral therapy (ART) and if it should be universally implemented. Data presented today at the XIX International AIDS Conference in Washington, D.C. show that treatment as prevention is “very cost-effective”.
