The National Institute of Allergy and Infectious Diseases (NIAID), the part of the National Institutes of Health that oversees the trial, concurs with this recommendation and has stopped this component of the study.

The trial is examining whether certain regimens of antiretrovirals taken once a day are at least as good as a standard antiretroviral regimen containing a drug combination taken twice a day. The study involves 1,571 HIV-infected volunteers on four continents who were randomly assigned to take one of three drug regimens:
