About Us

The Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) research program aims to defeat the rising HIV epidemic among adolescents and young adults in the United States. The overarching goal of the ATN is to increase awareness of HIV status in youth and, for those diagnosed with HIV, increase access to health care. The ATN develops and conducts behavioral, community-based, translational, therapeutic, microbicide and vaccine trials in HIV-at-risk and HIV-infected youth ages 12 to 24 years, with a focus on the inclusion of minors.

ATN research is conducted through collaborations within the network and with researchers in other institutions. The ATN currently includes three research program projects (or U19s) and a Coordinating Center. Each U19 supports a research program with a well-defined research focus supported by core infrastructures as well as subject recruitment and enrollment capacity. These research program projects are:

Logo for CARES project

CARES, a comprehensive community-based project focused on optimizing the HIV prevention and treatment continuum for youth at HIV risk, acutely infected and with established HIV infection.

iTech study logo

iTech, an innovative technology project which aims to impact the HIV epidemic by conducting innovative, interdisciplinary research on technology-based interventions across the HIV prevention and care continuum for adolescents and young adults.

Scale It Up project logo

Scale it Up, a research program aimed at the development and assessment of effectiveness of theoretically and developmentally sound interventions focused on improving self-management among HIV-positive and at-risk youth.

The ATN Coordinating Center is located at the University of North Carolina at Chapel-Hill. The Coordinating Center provides support, coordination, and operational infrastructure to the three ATN research programs and provides expertise in project management, data management, and statistics to the ATN. The Coordinating Center manages multiple network studies (learn more here), collaborating with principal investigators and study sites at healthcare organizations and universities around the country.

ATN is funded by the National Institutes of Health (NIH) through the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) with supplemental funding from the National Institute of Mental Health (NIMH), the National Institute on Drug Abuse (NIDA), and the National Institute on Minority Health and Health Disparities (NIMHD).

About the Eunice Kennedy Shriver National Institute of Child Health and Human Development: NICHD conducts and supports research in the United States and throughout the world on fetal, infant and child development; maternal, child and family health; reproductive biology and population issues; and medical rehabilitation.
