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 study sites, 4 in South Africa and 1 each in Uganda, Zimbabwe, Zambia, Malawi, Tanzania and India between November 9, 2006 and March 19, 2010.

Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Infants and children 6 - 36 months of age (lower age limit changed to 2 months in Protocol Version 4.0) were stratified by age (2-<6 months, 6-<12 months and >=12 months) and randomly assigned to receive either AZT/3TC/NVP or AZT/3TC/LPV/r. One subject was randomized but never started study treatment.

The sponsor cannot require changes to the communication and cannot extend the embargo. The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo. Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed.; Restriction Description: In accordance with the Clinical Trial Agreement between NIAID (DAIDS) and company collaborators, NIAID (DAIDS) provides companies with a copy of any abstract, press release, or manuscript prior to submission for publication with sufficient time for company review and comment.
