The Safety and Effectiveness of Two Forms of Saquinavir Combined With Other Anti-HIV Drugs in HIV-Infected Infants and Children
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.
To determine the pharmacokinetic properties, tolerance and safety of 2 formulations of saquinavir, given in combination with 2 nucleoside antiretroviral drugs (part 1) or in combination with nelfinavir and nucleoside antiretroviral drugs (part 2), in HIV-infected infants and children.
Condition or disease
Drug: Nelfinavir mesylateDrug: Saquinavir
This Phase I/II study will be conducted in 2 parts each lasting at least 24 weeks. Pharmacokinetics and safety data for part 1, a treatment regimen containing saquinavir and nucleoside antiretrovirals, will be collected for 8 weeks before proceeding to part 2. During the first 8 weeks, pharmacokinetic data will be analyzed to allow dose adjustments for individual patients and to confirm the starting dose estimates for part 2. In addition, safety data will be reviewed to ensure that saquinavir is well tolerated with nucleoside antiretrovirals before it is combined with a second protease inhibitor. In part 2, saquinavir will be combined with nelfinavir, a protease inhibitor recently approved for use in children. The pharmacokinetics and safety profile of these drugs in combination will be determined.

Ages Eligible for Study:
6 Months to 13 Years (Child)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Patients must have:
HIV infection according to standard definitions employed by the Pediatric AIDS Clinical Trials Group.
Laboratory evidence of immunosuppression (Centers for Disease Control and Prevention [CDC] categories 2 and 3), or symptomatic HIV disease (CDC categories A, B, and C).
At least 4 patients (2 in each parts 1 and 2) will be enrolled in each of three age strata:
6 months to 2 years; greater than 2 years to 6 years; and greater than 6 years to 13 years. NOTE:
For the purposes of analysis only, patients will be stratified by age.
1. Patients must be protease inhibitor therapy naive.
Antiretroviral agents other than those prescribed by the investigator.
Biologic response modifiers (other than erythropoietin, G-CSF, short course [<14 days] corticosteroids, or intravenous immune globulin).
Other investigational drugs.
Drugs known to significantly interact with saquinavir and/or nelfinavir. Patients must be protease inhibitor therapy naive.
