Official title

A Phase II Study to Demonstrate That Therapy With Efavirenz (EFV) and Other Antiretroviral Drugs Can Be Interrupted Without Selecting for EFV-Resistant Virus, and Relation to Kinetics of Drug Elimination

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to find out if anti-HIV drugs can be stopped without the virus becoming resistant to the drugs. The study will also examine how fast anti-HIV drugs leave the body. Not all HIV-infected patients may require continuous and indefinite anti-HIV therapy. There is evidence that stopping anti-HIV therapy will not make the virus resistant to efavirenz (EFV), an anti-HIV drug that remains in the body longer than most treatment drugs. In another study, patients were treated with EFV, zidovudine (ZDV), and lamivudine (3TC). The patients' virus was controlled despite the fact that some patients missed medication dosages. Many patients stop anti-HIV therapy because of negative effects. This study will examine the body's ability to fight and control virus in patients who stop therapy.
