Blood Levels of Anti-HIV Drugs Used in Combination Regimens in HIV Infected Children
Intensive Pharmacokinetic Studies of Antiretroviral Drug Combinations in Children

Detaillierte Beschreibung
Because all of the available non-nucleoside reverse transcriptase inhibitors (NNRTIs) and protease inhibitors (PIs) are metabolized by and affect hepatic cytochrome enzymes, combinations of two or more of these drugs produce complex pharmacokinetic (PK) interactions. However, little data exist regarding PK of anti-HIV drug combinations in the pediatric population. The purpose of this study is to assess steady-state PK of the following anti-HIV regimens: TDF and EFV or NVP; TDF and DRV with or without EFV; and TDF and RTV with or without EFV. In addition, this study will evaluate how age, length of treatment, adverse effects, and genes affect children's response to different anti-HIV combinations.
This study will last between 1 and 7 weeks. Participants in this study will be grouped based on the treatment regimen they are receiving or about to initiate. There are three groups in this study. Group D participants will receive TDF and EFV or NVP; Group E participants will receive TDF and DRV with or without EFV; and Group F participants will receive TDF and RTV with or without EFV. The inclusion of EFV or NVP will be dependent on each participant's prescribed regimen. Participants within each group will be stratified by age and how long they have been receiving their anti-HIV regimens. Antiretrovirals will not be provided by this study.
Most participants will have two study visits. The first visit will occur at study entry. Medical history, a physical exam, and blood collection will occur. The second visit will occur within 35 days of study entry and will take approximately 24 hours. Blood collection for PK studies, a physical exam, and medical history will be done at this visit. Urine collection will occur at all visits for female participants.
Participants will undergo PK testing at least 14 days after initiating their study regimens. Participants will be given a dose of their anti-HIV medications with food. A blood sample will be taken before dosing. Blood samples will also be taken at 1, 2, 4, 6, 8, 12, and 24 hours after dosing. Participants in Groups E and F may need to repeat PK testing within 6 weeks of initial PK testing at the discretion of the investigator.
