Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Study participants were recruited at 10 sites from 7 African countries: 3 from South Africa, 2 from Kenya, and 1 each in Botswana, Malawi, Uganda, Zambia and Zimbabwe, between November 2006 to July 2008. The Botswana site enrolled participants from two locations.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
HIV-infected, treatment-naive women, at least 13 years of age with CD4+ count<200 cells/mm^3. Four participants were randomized but did not start treatment.

Reporting Groups
  Description
NVP/NVP For participants had single dose Nevirapine (SD NVP) exposure prior to study entry, Emtricitabine capsules(FTC) 200mg (1 capsule orally), Tenofovir disproxil fumerate (TDF) 300mg (1 tablet orally), and NVP 200mg (1 tablet orally) once daily in the morning for the first 14 days, then twice daily after 14 days. FTC and TDF may be replaced by the combination drug FTC/TDF. Participants who discontinue NVP will receive Lopinovir/Ritonovir (LPV/RTV)400/100mg (3 capsules orally) twice daily plus two more Nucleoside reverse transcriptase inhibitors (NRTIs). Following the review on 6 October 2008, the Data Safety Monitoring Board(DSMB) recommended release of the results from this arm.
NVP/LPV_r For participants had SD NVP exposure prior to study entry, FTC 200mg (1 capsule orally) and TDF 300mg (1 tablet orally) daily and LPV/RTV 400/100mg (3 capsules orally) twice daily. FTC and TDF may be replaced by the combination drug FTC/TDF. Participants who discontinue LPV/RTV will receive NVP 200mg (1 tablet orally) daily for 14 days before taking it twice daily. plus 2 more NRTIs. Following the review on 6 October 2008, the DSMB recommended release of the results from this arm.
NoNVP/NVP For participants had NO SD NVP exposure prior to study entry, FTC 200mg (1 capsule orally), TDF 300mg (1 tablet orally), and NVP 200mg (1 tablet orally) once daily for the first 14 days, then twice daily after 14 days. FTC and TDF may be replaced by the combination drug FTC/TDF. Participants who discontinue NVP will receive LPV/RTV 400/100mg (3 capsules orally) twice daily plus two more NRTIs.

FTC and TDF may be replaced by the combination drug FTC/TDF. Participants who discontinue LPV/RTV will receive NVP daily 200mg (1 tablet orally) for 14 days before taking it twice daily plus 2 more NRTIs.

[1] World Health Organization (WHO) produced WHO Disease Staging System for HIV Infection and Disease in Adults and Adolescents. It is an approach for use in resource limited settings in studies of progression to symptomatic HIV disease. There are 4 stages of disease staging, 1 being the least severe and 4 being the most severe disease stage based on the HIV related symptoms and diagnoses.

Measure Type Secondary
Measure Title Number of Participants Who Experienced Treatment-related Toxicity That Led to Discontinuation of Randomized Regimen.
Measure Description The outcome is defined as treatment-related toxicity (as evaluated by sites), regardless of grade, that led to discontinuation of randomized regimen. For NVP/NVP and NVP/LPV_r arms, data through DSMB review cutoff (October 6, 2008) were used to report the outcome. For NoNVP/NVP and NoNVP/LPV_r arms, since the follow-up continued as planned, data through overall study were used.
Time Frame Through database cutoff for DSMB review (by October 6, 2008) for NVP/NVP and NVP/LPV_r. Throughout study for NoNVP/NVP and NoNVP/LPV_r.
