E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objectives are: • To evaluate the steady-state pharmacokinetics (PK) of rilpivirine and determine the appropriate dose of rilpivirine in combination with other antiretrovirals (ARVs) in participants aged ≥2 to <12 years with a body weight of <25 kg. • To evaluate the safety and tolerability of rilpivirine in combination with other ARVs in participants aged ≥2 to <12 years over a 24-week treatment period. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are: • To evaluate the safety and tolerability of rilpivirine in combination with other ARVs over a 48-week treatment period. • To evaluate the efficacy of rilpivirine in combination with other ARVs over a 24- and 48-week treatment period. • To evaluate population PK and PK/pharmacodynamic (PD) relationships for safety and efficacy of rilpivirine in combination with other ARVs. • To assess resistance in case of loss of virologic response to rilpivirine in combination with other ARVs. • To evaluate treatment adherence to rilpivirine in combination with other ARVs over a 24 and 48 week treatment period. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Each potential participant must satisfy all of the following criteria to be enrolled in the study: 1. Aged ≥2 to <12 years at screening. 2. Weighing at least 11 kg at screening. 3. Have documented chronic HIV-1 infection. 4. On a stable ARV regimen for at least 6 months prior to screening and virologically suppressed, with documents evidence of at least 2 plasma viral loads <50 HIV-1 RNA copies/mL: one within 2-12 months prior to screening and one at screening. 5. Criterion deleted 6. Parent(s) (preferably both if available per local requirements) or the participant's legally acceptable representative[s]) must sign an ICF indicating that he or she understands the purpose of and procedures required for the study. Assent is also required from participants capable of understanding the nature of the study (typically aged ≥ 7 years) 7. Can comply with the protocol requirements. 8. Can switch from any ARV class. 9. Never been treated with a therapeutic HIV vaccine. 10. Otherwise healthy and medically stable on the basis of physical examination, medical history, vital signs, and 12-lead ECG performed at screening. If there are abnormalities, they must be consistent with the underlying illness in the study population. This determination must be recorded in the participant’s source documents and initialed by the investigator.

|
E.4 | Principal exclusion criteria |
Any potential participant who meets any of the following criteria will be excluded from participating in the study: 1. Have previously documented HIV-2 infection. 2. Have known or suspected acute (primary) HIV-1 infection. 3. Taken any disallowed concomitant therapies within 4 weeks before the planned first dose of study intervention. 4. A positive HLA-B*5701 test at screening (when the investigator considers ABC in the background regimen). In case of a positive test, ABC cannot be administered, but instead, the investigator can select another ARV in the background regimen. HLA-B*5701 testing is not required for participants with prior documented negative results. 5. Any current or history of adrenal disorder. 6. Any active clinically significant diseases (eg, pancreatitis, cardiac dysfunction, active and significant psychiatric disorders, clinical suspicion of adrenal insufficiency, and hepatic impairment) or findings at screening or medical history that, in the investigator’s opinion, would compromise the outcome of the study. 7. A history of virologic failure to ARVs with or without availability of an HIV-1 genotype result at the time of failure. 8. Documented genotypic evidence of resistance to RPV or to the selected background ARVs from historical data available in the source documents. 9. A known clinically significant allergy, hypersensitivity, or intolerance to RPV or its excipients or to the selected background ARVs. 10. Criterion modified per Amendment 1 10.1 Received an investigational intervention (including investigational vaccines) containing an active substance or used an invasive investigational medical device within 90 days before the planned first dose of study intervention.

E.5 End points |
E.5.1 | Primary end point(s) |
1. Area under the plasma concentration-time curve from time of administration up to 24 hours post dose of rilpivirine, as derived from the intensive PK assessments. 2. Incidence of grade 3/4 AEs, SAEs, HIV-related events (including acquired immune deficiency syndrome [AIDS]-defining illnesses and Stage-3-defining Opportunistic Illnesses in HIV Infection), and AEs leading to discontinuation of study intervention through 24 weeks of study treatment.

Proportion of participants with HIV-1 RNA <50 and ≥50 copies/mL using the Food and Drug Administration (FDA) Snapshot approach through 24 and 48 weeks of study treatment. 4. Proportion of participants with HIV-1 RNA <400 and ≥400 copies/mL using the FDA Snapshot approach through 24 and 48 weeks of study treatment 5. Pharmacokinetic parameters of RPV (other than area under the plasma concentration-time curve [AUC]), as derived from the intensive PK assessments. 6. Pharmacokinetic parameters of rilpivirine, as derived by population PK modeling, through 24 and 48 weeks of study treatment. 7. Viral genotype at the time of virologic failure through 24 and 48 weeks of study treatment. 8. Treatment adherence, as assessed by the Pediatric European Network for the Treatment of AIDS (PENTA) adherence questionnaire and by study intervention accountability, through 24 and 48 weeks of study treatment.
