An Open Label Pharmacokinetic, Safety And Efficacy Study Of Maraviroc In Combination With Background Therapy For The Treatment Of HIV-1 Infected, CCR5 -Tropic Children
An Open-label, Multicenter, Multiple-dose Pharmacokinetic, Safety And Efficacy Trial Of Maraviroc In Combination With Optimized Background Therapy For The Treatment Of Antiretroviral-experienced Ccr5-tropic Hiv-1 Infected Children 2 - <18 Years Of Age
The primary purpose of this study is to determine the pharmacokinetic properties (what the body does to maraviroc) and to determine a suitable dosing schedule of maraviroc in HIV-1 infected children and adolescents. This study will also determine whether maraviroc is safe to use in children and adolescents.

Phase 2
Allocation: Non-Randomized
Endpoint Classification: Pharmacokinetics Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Human Immunodeficiency Virus (HIV)
Drug: Maraviroc
Maraviroc will be administered twice daily either as a liquid or tablet formulation, depending on the age of the subject. The dosage administered will be dependent upon the subject's body surface area as well as the background therapy.
Other Name: Selzentry
Experimental: Maraviroc

Subjects will be stratified by age and formulation into one of the following cohorts:

Cohort 1: ≥2-<6 years of age, maraviroc liquid formulation; Cohort 2: ≥6-<12 years of age, maraviroc tablet formulation; Cohort 3: ≥6-<12 years of age, maraviroc liquid formulation and Cohort 4: ≥12-<18 years of age, maraviroc tablet formulation.

Intervention: Drug: Maraviroc
