Pharmacokinetic(PK): Maraviroc PK Parameter, Average Plasma Concentration (Cavg), Trough Concentration(Cmin), Maximum Plasma Concentration (Cmax) Primary · Week 2 and Week 48 (0, 1, 2, 4, 6, 8, 12 hours post-dose)

Cavg: calculated as area under the curve divided by a dosing interval of 12 hours. Cmin: directly observed plasma concentration prior to the next dose. Geometric Coefficient of Variation is defined as the geometric standard deviation to the power of the reciprocal of the geometric mean.

Treatment Discontinuation: Secondary Reasons- Serious Adverse Event (SAE) Related to Study Drug Primary · Baseline up to 5 years

The primary reason for a participant discontinuing from study drug or the clinical study was recorded in the source documents as well as the case report form. A discontinuation had to be reported immediately to the study medical monitor or his/her designated representative if it was due to an SAE and was considered as a secondary reason.

Percentage of Participants With HIV-1 RNA <400 Copies/mL Through Week 48 Using Missing, Discontinuation = Failure (MD=F) Approach Secondary · Week 24 and Week 48 post-treatment

The proportion of participants who achieved HIV-1 RNA \<400 copies/mL at week 24 or 48 was assessed according to Food and Drug Administration's (FDA's) Missing, Switch, Discontinuation'=Failure (MSDF) Snapshot algorithm. The algorithm uses the plasma HIV-1 RNA in the Week 24 or 48 visit window, follows the "virology-first principle" and considers a participant who has a missing plasma HIV-1 RNA, or switches to prohibited ARV regimen or discontinues from the study or study drug for any reason, or dies, as a failure.

Sponsor's own description

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.
