Safety, Tolerability, Drug Interactions, and Antiviral Activity of Rilpivirine in Antiretroviral-Naive HIV-Infected Children Less Than 12 Years of Age
A Phase I/II, Open-Label Trial to Evaluate the Safety, Tolerability, Pharmacokinetics and Antiviral Activity of Rilpivirine in Antiretroviral Naive HIV-1 Infected Children, < 12 Years of Age

Development of tolerable and effective antiretroviral (ARV) drugs for use in children and adolescents remains a high priority. First-line therapy with non-nucleoside reverse transcriptase inhibitors (NNRTIs) has proven to be effective for HIV-1-infected infants, children, and adolescents. This study will evaluate the safety, effectiveness, and dosing levels of the NNRTI rilpivirine (RPV) when given with two other ARV drugs in treatment-naive, HIV-1-infected children less than 12 years of age.

This study will enroll HIV-1-infected children less than 12 years of age who are naive to antiretroviral therapy (ART) (have never taken ARV drugs). Study participants will be assigned to 1 of 2 cohorts based on age. Cohort 1 will include children at least 6 years of age to less than 12 years of age. Cohort 2 will include children at least 2 years of age to less than 6 years of age. Each cohort will consist of two stages: Stage 1 and Stage 2. Stage 1 will be the initial dose finding stage. Participants will begin treatment with daily RPV and 2 nucleoside reverse transcriptase inhibitors (NRTIs). The 2 NRTIs will be selected by the site investigator but will not be provided through the study. This stage of the study will involve intense pharmacokinetic (PK) sampling to evaluate the safety, tolerability, and antiviral activity of RPV, which will allow for the selection of an RPV dose to use in Stage 2 of the study. Participants in both cohorts will remain on RPV-based therapy for up to 48 weeks.

Study enrollment will begin with Cohort 1. Once data from Cohort 1 has been reviewed and an RPV dose has been approved, enrollment for Cohort 2 will begin.

Study participation will include at least 12 study visits over 48 weeks. Participants who complete 48 weeks of RPV treatment and are benefiting from the drug will continue on the study and receive RPV as part of a long-term safety follow-up for a minimum of 4 additional years. Study visits in this stage of the study will occur every 24 weeks.

At most visits, participants will give a medical history and undergo a physical exam, blood collection, and urine collection. At some visits, participants will also undergo an electrocardiogram (ECG), adrenocorticotropic hormone (ACTH) stimulation test (consisting of blood collection and an injection of ACTH), and determination of the participant's stage of sexual development.

Phase 1
Phase 2
Allocation: Non-Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
HIV Infections
Drug: Rilpivirine

For Cohort 1, Stage 1: RPV will be given orally as a 25-mg film-coated tablet (or for dosing in younger children, as granules [2.5 mg/g]) each day with a meal.

For Cohort 1, Stage 2: The dose of RPV will be determined once Cohort 1, Stage 1 data are available.

For Cohort 2: The dose of RPV will be determined once Cohort 1 data are available.

Inclusion Criteria - Stage 1, Step 1 and Stage 2

  • A confirmed HIV-1 infection. More information on this criterion can be found in the protocol.
  • Participant has never been treated with an HIV vaccine
  • No evidence of prior ARV drug use with the exception of prior use of zidovudine (AZT) for up to 6 weeks to prevent mother-to-child transmission
  • HIV-1 plasma viral load (VL) at screening greater than 500 HIV-1 RNA copies/mL but less than or equal to 100,000 HIV-1 RNA copies/mL (assayed by RNA polymerase chain reaction [PCR] standard specimen procedure) Note: Participants may be re-screened once only, if their baseline VL does not meet the entry criteria.
  • In the judgment of the investigator, it is appropriate to initiate ARV therapy based on the participant's medical condition and taking into account guidelines for the treatment of HIV-1 infection in children
  • Results from the genotypic resistance testing at screening demonstrate sensitivity to the selected NRTIs for the chosen background regimen
  • Able to swallow whole tablets (Cohort 1 initial dose only)
  • Female participants who are of childbearing potential and who are engaging in sexual activity that could lead to pregnancy, must use two adequate birth control methods while on study and for 4 weeks after stopping study drug. More information on this criterion can be found in the protocol.

Inclusion Criteria - Stage 1, Step 2

  • Participants belonging to a cohort that failed Stage 1 Step 1 initial dose that meet the following criteria (as determined by the study team): Are able to have an adjustment in study drug dose (and the new dose would not exceed 25 mg) and appear to have room to stay within therapeutic range on the new dose

Exclusion Criteria - Stage 1, Step 1 and Stage 2

  • Having documented genotypic evidence of RPV resistance. More information on this criterion can be found in the protocol.
  • Documented evidence of infection during breastfeeding by a mother taking NNRTI-based ART. If there are no data or no history available then the participant would be eligible as long as all other inclusion and exclusion criteria are fulfilled.
  • Documented evidence of maternal NNRTI use during pregnancy. If there are no data or no history available then the participant would be eligible as long as all other inclusion and exclusion criteria are fulfilled.
  • Previously documented HIV-2 infection in participant or participant's mother. If there are no data or no history available then the participant would be eligible as long as all other inclusion and exclusion criteria are fulfilled.
