Details and patient eligibility


The purpose of this study is to see if it is safe and effective to give adefovir (a new anti-HIV drug) plus nelfinavir to HIV-infected children who are already receiving other anti-HIV medications.

Full description

During the first phase of the study (Days 1-6), the safety and tolerability of multiple doses of ADF is assessed when administered simultaneously with the patient's reverse transcriptase inhibitor (RTI) regimen. The second phase begins on Day 7 when nelfinavir is added to the therapy regimen for an additional 15 weeks. ADF pharmacokinetics are measured on Days 1, 2, and 7 (on a subset of 18 patients); peak and trough samples are collected on Day 28.
