Primary Outcome Measures

  • Intensive 0-12h PK sampling for plasma levels of LPV and SQV, and blood sampling. CD4 viral load safety lab every 3 months. [ Time Frame: 96 week ]

Enrollment: 50
Study Start Date: October 2003
Study Completion Date: November 2008
Primary Completion Date: November 2008 (Final data collection date for primary outcome measure)

Arms Assigned Interventions
Other: double-boosted PI
double-boosted protease inhibitor combination
Drug: Lopinavir/r plus saquinavir

lopinavir/ritonavir 230/57.5 mg/m2 orally twice daily and saquinavir 50 mg/kg orally twice daily

Detailed Description:

The PK and 24 week data has been published in Pediatric Infectious Diseases Journal. It showed that plasma drug concentrations of saquinavir, lopinavir and ritonavir were at the higher limits of expected ranges for adult treatment at approved dosages (1000/100 mg BID for saquinavir, 400/100 mg BID for lopinavir/r). The regimen was well tolerated and showed significant CD4 rise and VL decline at 48 weeks.
