Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
HIV-infected pregnant women were recruited from antenatal clinics at DAIDS Clinical Trials Sites in Zimbabwe, South Africa, Uganda & Tanzania between May 14, 2008 & January 20th 2010. 1700 mother/infant pairs were enrolled & infants were given daily doses of Nevirapine for 6 weeks at which point there were randomized to placebo or extended NVP.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Infants were excluded from randomization if in first 42 days: had a positive HIV-1 DNA PCR, breastfeeding was discontinued, never initiated or permanently discontinued open-label NVP, certain graded abnormal labs, skin rash grade2B or higher, clinical hepatitis, serious illness/condition that prevented compliance, or use of rifampin/ketoconazole.

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
The rate of maternal highly active antiretroviral therapy use was higher than expected in our study. Thus there were fewer infant infections which decreased the power to detect differences in HIV transmission risks between study groups.
