Official Title: A Pilot Study of Safety, Effectiveness, and Adherence of Lamivudine/Zidovudine and Efavirenz (3TC/ZDV + EFV) to Treat HIV-1 Infection in Senegal

Further Study Details: 
Primary Outcomes: Virologic efficacy, defined as HIV-1 viral load less than 200 copies/ml measured by Week 24 and confirmed by repeat testing within 30 days; treatment-related toxicity of Grade 3 or higher at any times during the first 24 weeks of treatment
Expected Total Enrollment:  44

Study start: February 2005

Despite a relatively low prevalence of HIV infection, all HIV subtypes have been documented in Senegal. Data on mutations that confer resistance to antiretroviral (ARV) drugs are limited to HIV subtype B; adherence data are also limited. The study will evaluate the safety and efficacy of an ARV regimen given to treatment-naive HIV infected adults and adolescents. The study will also examine the characteristics of virologic failure and adherence in this treatment group. Participants will be recruited at two sites in Dakar, Senegal.

This study will last 96 weeks. At study entry, all study participants will be given an ARV regimen of lamivudine/zidovudine twice daily and efavirenz once daily. If toxicity or treatment failure occurs, some participants may require changes in their ARV regimens. There will be 14 study visits; a physical exam, blood collection, and sociodemographic and medication history assessments will occur at each visit. Participants will also be asked to complete quality-of-life and adherence questionnaires.
