NIH AIDS Clinical Trials Information Service Identifier:
First received: November 2, 1999
Last updated: June 23, 2005
Last verified: May 1999
To evaluate the single dose pharmacokinetic profile of Viracept pediatric powder formulation administered to HIV infected or exposed children and infants (0 to 13 years of age). An evaluation of the relative bioavailability of the pediatric powder formulation vs. a standard tablet formulation in older children (7 to 13 years of age) will also be conducted.

Condition Intervention Phase
HIV Infections Drug: Nelfinavir mesylate Phase 1

Further study details as provided by NIH AIDS Clinical Trials Information Service:

Estimated Enrollment: 24
Detailed Description:

This is a study of the safety, tolerability and pharmacokinetics of a Viracept pediatric powder formulation with milk or formula. First a single dose will be administered. After the patient population is divided into 4 groups by age, an optimal dose will be determined for each group. This optimal dose will be given 3 times a day for a 6 week primary observation period, plus an optional 6 month extension.

NOTE: During the single dose portion of this study, patients may be untreated or may continue treatment with their current nucleoside antiretroviral therapy. During multiple dose administration of Viracept, antiretroviral therapy will be intensified by either adding or modifying therapy. Antiretroviral therapies will be limited to those currently licensed including zidovudine, lamivudine, stavudine, didanosine or zalcitabine.


Ages Eligible for Study:   up to 13 Years   (Child)
