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.

Endpoint Classification: Pharmacokinetics Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
||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
Primary Outcome Measures:
- To determine the safety and tolerability of maraviroc in HIV-infected children and adolescents. [ Time Frame: 48 weeks ] [ Designated as safety issue: Yes ]
- To determine the pharmacokinetic profile(s) and dosing schedule(s) for maraviroc in treatment experienced HIV-infected children and adolescents on different background therapies; [ Time Frame: 48 weeks ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- Describe the efficacy of multiple dose administration of maraviroc in treatment experienced children infected with CCR5 tropic HIV-1; [ Time Frame: 48 weeks ] [ Designated as safety issue: No ]
- Describe tropism changes over time. [ Time Frame: 48 weeks ] [ Designated as safety issue: No ]

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.
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.
