A PK and Salvage Study for Children With HIV-infection

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00476359
Recruitment Status : Completed
First Posted : May 22, 2007
Last Update Posted : March 27, 2015
Roche for trial and Saquinavir,and Abbott for Kaletra
Information provided by (Responsible Party):
The HIV Netherlands Australia Thailand Research Collaboration

Brief Summary:
To evaluate the pharmacokinetics (PK) of LPV/r with saquinavir in HIV-1 infected children. To evaluate treatment response (clinical, immunological and virological) to LPV/r, SQV in Thai children.

Condition or disease Intervention/treatment Phase
HIV Infections Drug: Lopinavir/r plus saquinavir Phase 4

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.
