studies

 

Our studies strive to prevent HIV infection through the use of antiretroviral drugs, interventions for substance use, behavioral risk reduction, and structural interventions. HPTN research studies are developed by protocol teams that include CTU investigators and recognized experts in HIV prevention. As study protocols are developed, they undergo a rigorous intra- and extra-Network review process that ensures compliance with current ethical guidelines and regulatory procedures.
