Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
This study was conducted between 28 April 2005 and 24 August 2007 at 38 study centers in the United States, Canada, France and Thailand. Patients were randomized to receive saquinavir/ritonavir 1000/100 mg PO BID plus emtricitabine/tenofovir 200/300 mg PO QD or lopinavir/ritonavir 400/100 mg PO BID plus emtricitabine/tenofovir 200/300 mg PO QD .
