简要总结
The purpose of this study is to evaluate the steady state pharmacokinetics (PK) of rilpivirine (RPV) and determine the appropriate dose of RPV in combination with other antiretrovirals (ARVs) in participants aged greater than or equal to 2 to less than 12 years and to evaluate the safety and tolerability of RPV in combination with other ARVs in participants of same age group over a 48-week treatment period with primary endpoint at Week 24.
详细描述
Participants infected with human immunodeficiency virus type 1 (HIV-1) are routinely treated with combinations of multiple drugs which reduces HIV-1 ribonucleic acid (RNA) to undetectable levels in a substantial proportion of participants and counteracts the risk of viral resistance development. RPV is a potent non-nucleoside reverse transcriptase inhibitor (NNRTI) with in vitro activity against wild type (WT) HIV-1 and against NNRTI-resistant HIV-1 mutants. A medical need still exists for the development of age/weight appropriate formulations in children less than (<) 12 years of age. In this study, participants will switch to RPV plus other ARVs. The primary analysis will be performed at Week 24. A participant will be considered to have completed the study if he or she has completed assessments at Week 48 of the study intervention phase. The total study duration for each participant, including screening and study intervention phases, will be approximately 54 weeks. Key efficacy assessments include determination of plasma HIV-1 RNA viral load and measurement of CD4+ cell count. Key safety assessments will include the monitoring of (serious) adverse events ([S]AEs) and HIV-related events, clinical laboratory tests, cardiovascular safety monitoring (vital signs and 12 lead electrocardiogram [ECGs]), and physical examination (including growth).

研究组 & 干预措施
Rilpivirine (RPV) (25 mg or adjusted weight-based dose)
Participants will receive rilpivirine (RPV 25 milligram [mg], adjusted weight-based dose) orally once daily in combination with an investigator selected background regimen (that is investigator-selected antiretrovirals [ARVs] such as nucleoside/nucleotide reverse transcriptase inhibitor [N{t}RTIs] and integrase inhibitors) for 48 weeks.
干预措施: Rilpivirine (Drug)
Rilpivirine (RPV) (25 mg or adjusted weight-based dose)
Participants will receive rilpivirine (RPV 25 milligram [mg], adjusted weight-based dose) orally once daily in combination with an investigator selected background regimen (that is investigator-selected antiretrovirals [ARVs] such as nucleoside/nucleotide reverse transcriptase inhibitor [N{t}RTIs] and integrase inhibitors) for 48 weeks.

结局指标
主要结局
Area Under the Plasma Concentration-time Curve From Time of Administration up to 24 Hours Postdose (AUC[0-24h]) of Rilpivirine 12.5 mg (for <20 kg Group)
时间窗: Predose up to 24 hour post-dose at anytime during Day 28 to Day 32 (Week 4)
AUC(0-24h) was defined the area under the plasma concentration-time curve from time of administration up to 24 hours postdose of rilpivirine. As planned, data was not summarized for arms where number of participants analyzed was less than 3. Only individual participant data was available and reported in this outcome measure. Out of the 2 participants weighing \<20 kg who received rilpivirine 15 mg, 1 participant switched to rilpivirine 12.5 mg group after the first 4 weeks. This participant was counted in the \<20 kg rilpivirine 12.5 mg group for the pharmacokinetic assessments, hence the number of participants analyzed for this outcome measure in this arm are exceeding the participants that started this arm. As per protocol, the intensive PK samples were collected at anytime during Day 28 to Day 32 after first dose at the specified dose regimen.
