A Study to Compare Anti-HIV Drugs Given Twice a Day or Once a Day, With or Without Direct Observation

Summary

Anti-HIV drug therapy works best when the drugs are taken exactly as prescribed by a doctor. Because anti-HIV therapy often involves multiple drugs, some people have difficulty taking them all correctly. The easier it is to take anti-HIV drugs, the more likely people will take them as prescribed and get the best results. This study will see if people are more successful in taking anti-HIV drugs once a day or twice a day. It also will determine if having a health care professional oversee each weekday dose helps people control their HIV infection. The study will compare taking a three-drug combination twice a day versus taking a three-drug combination just once a day. The study will also compare patients taking the drugs on their own to patients taking the drugs in the presence of a clinical worker. Viral load (amount of HIV in the blood) and drug side effects will be measured.
