About the HPTN | The HIV Prevention Trials Network

Our Mission

The HPTN is dedicated to the discovery and development of new and innovative research strategies to reduce the acquisition and transmission of HIV.

The HIV Prevention Trials Network (HPTN) is a worldwide collaborative clinical trials network that brings together investigators, ethicists, community and other partners to develop and test the safety and efficacy of interventions designed to prevent the acquisition and transmission of HIV. HPTN studies evaluate new HIV prevention interventions and strategies in populations and geographical regions that bear a disproportionate burden of infection. The HPTN is committed to the highest ethical standards for its clinical trials and recognizes the importance of community engagement in all phases of the research process.

The HPTN research agenda is focused primarily on the use of integrated strategies: use of antiretroviral drugs (antiretroviral therapy and pre-exposure prophylaxis), interventions for substance abuse, particularly injection drug use, and behavioral risk reduction interventions with structural interventions.

The HPTN was established in 2000, building on the work of the HIV Network for Prevention Trials (HIVNET). HPTN’s Leadership and Operations Center (LOC), is based at FHI 360, Durham, North Carolina. The Laboratory Center (LC) is at Johns Hopkins University, Baltimore, Maryland and the Statistical and Data Management Center (SDMC) is housed within the Statistical Center for HIV/AIDS Research and Prevention (SCHARP) at the Fred Hutchinson Cancer Research Center in Seattle, Washington. The HPTN Modelling Centre, part of the SDMC, is a collaboration between the Department of Infectious Diseases Epidemiology at Imperial College London and SCHARP.

HPTN receives funding from three NIH institutes: the National Institute of Allergy and Infectious Diseases, the National Institute of Mental Health and the National Institute on Drug Abuse.
