The AIDS clinical trials information service (ACTIS).

The AIDS Clinical Trials Information Service fulfills its mission, as mandated by the HOPE legislation of 1988, by providing current information on clinical trials nationwide that evaluate experimental drug and biological treatments for adults and children with HIV/AIDS. Thousands of healthcare providers, patients, and families rely on this telephone-based service each year for information about options in the management of HIV disease. Specially trained reference specialists provide customized responses to callers based on health status and level of understanding about the disease. The service is sponsored collaboratively by four federal U.S. Public Health Service agencies.
