A Phase 1/2 interventional study of Oral Cabotegravir (CAB) and Oral Rilpivirine (RPV) in HIV Infections, sponsored by National Institute of Allergy and Infectious Diseases (NIAID). Completed at 19 sites in 5 countries. Open to participants aged 12 Years to 17 Years. Per ClinicalTrials.gov, last updated 2026-01-28.
Sponsored by National Institute of Allergy and Infectious Diseases (NIAID) · Phase 1/2, Interventional, and Treatment
The purpose of this study was to determine the dosage for oral cabotegravir (CAB) and long-acting cabotegravir (CAB LA) and long-acting rilpiverine (RPV LA) and evaluate the safety, acceptability, tolerability, and pharmacokinetics (PK) of oral CAB, CAB LA, and RPV LA in virologically suppressed children and adolescents living with HIV.
IMPAACT 2017 was a Phase I/II, multi-center, open-label, non-comparative dose-finding study with the primary objective of evaluating the safety, acceptability, tolerability, and PK of oral cabotegravir (CAB) and long-acting cabotegravir (CAB LA) as well as long-acting rilpivirine (RPV LA) in adolescents living with HIV-1, who are 12 to \<18 years of age, ≥35kg, and virologically suppressed.
The study design included two cohorts of participants and five study steps. In Cohort 1, Step 1 participants received either oral CAB or oral rilpivirine (RPV) for at least four weeks and up to six weeks (maximum). In Cohort 1, Step 2 participants received intramuscular injectable formulations of the study products, either CAB LA or RPV LA. Cohort 1 participants were assigned either CAB (Cohort 1C) or RPV (Cohort 1R) based on their pre-study combination Antiretroviral Therapy (cART) regimen. Participants on a PI-based and/or NNRTI-based cART regimen were assigned to Cohort 1C, and participants on a non-boosted INSTI-based cART regimen were assigned to Cohort 1R. All participants continued their pre-study cART regimen during Cohort 1.
During Cohort 2, all participants discontinued their pre-study cART regimen and received both study products, CAB and RPV, at the doses established in Cohort 1. Cohort 2 participants enrolled to either Cohort 2A to receive both oral CAB + oral RPV (Step 3) followed by both CAB LA + RPV LA (Step 4) or Cohort 2B to directly receive both CAB LA + RPV LA without an oral lead-in phase (Step 5). If eligible, Cohort 1 participants were able to enroll into Cohort 2 (i.e., Cohort 1 Rollover). However, Cohort 2 participants who were not previously enrolled in Cohort 1 (i.e., Cohort 1-Naïve) were the primary group for analyses and conclusions. No participants enrolled into Cohort 2B, direct to injection (Step 5). Therefore, all references to Cohort 2 refer to Cohort 2A (Steps 3 and 4).
Two interim analyses were planned. The first interim analysis established the doses for Cohort 2 and determined whether to open Cohort 2 to Cohort 1 participants who met criteria to enter Cohort 2. The second interim analysis provided justification to open Cohort 2 to additional participants who were not previously enrolled in Cohort 1. A final analysis of Cohort 1 data was performed to confirm the final doses for Cohort 2.
Safety and PK evaluations were performed during Steps 1-5 and long-term safety follow-up (LSFU). Antiviral activity assessments were performed during Steps 1-5. Acceptability and tolerability were assessed during Steps 1-5 and LSFU, with all participants completing quantitative questionnaires and a subset of participants completing in-depth qualitative interviews. Additionally, parents/caregivers of a subset of U.S. participants from U.S. sites were also enrolled to complete a single in-depth qualitative interview. Because objectives related to parents/caregivers were exploratory, these outcomes are not described here.
Cohort 1 participants were followed for up to 64 weeks. Participants were followed for at least four weeks in Step 1 (oral phase) and at least 12 weeks in Step 2 (injection phase). All Step 2 participants were followed (on cART, off study product) for up to an additional 48 weeks as part of LSFU after their last study product injection. If eligible, Cohort 1 participants enrolled into Cohort 2 before completing LSFU. For Cohort 1, Step 1 participants not progressing to Step 2, the last visit was targeted to be completed 28 days after the participant's last oral study product use.
Cohort 2 participants were followed for up to 188 (Cohort 2B) or 192 (Cohort 2A) weeks. Participants were followed for at least four weeks in Step 3 (oral phase) and 92 weeks in Step 4/Step 5 (injection phase). After completing 92 weeks of follow-up in Step 4/Step 5 (injection phase), Cohort 2 participants who continued access to injectable study products through a mechanism external to the protocol exited the study. If it was not possible for participants to access injections of CAB LA + RPV LA from non-study sources at the completion of their Step 4 Week 96 or Step 5 Week 92 visit, participants remained in the study safety extension for up to 48 weeks. Participants who permanently discontinued injectable study product use during Cohort 2, Step 4/Step 5, or did not wish to continue to access the study products through the external mechanism after their Week 96 visit, were followed (on cART, off study product) for an additional 48 weeks as part of LSFU after their last study product injection, except for participants in the study safety extension. Participants in the study safety extension who decided to permanently discontinue injectable study product or who had not established access to study product after the 48 weeks in the study safety extension would exit the study (not enter LSFU). For Cohort 2, Step 3 participants not progressing to the injection phase, the last visit was targeted to be completed 28 days after the participant's last oral study product use. Female participants who discontinued study product use (either oral or injectable study product) due to pregnancy during Steps 1-5 were followed for an additional 48 weeks in LSFU to assess long-term safety and washout PK of the study products, except for participants in the study safety extension. Participants who became pregnant during the safety extension were only followed until the pregnancy outcome was determined.

Median Dimension of Quality of Life Scores
A commonly used 23-item Pediatric Quality of Life Inventory, the PedsQLTM, was used to measure physical, emotional, and social dimensions of health as well as school functioning. Question responses were used to generate scores from 0-100 (100 being the best quality of life) based on the PedsQLTM guidelines. The number of participants drops slightly for the school functioning result as not all participants are eligible to answer these school-related questions.

A commonly used 23-item Pediatric Quality of Life Inventory, the PedsQLTM, was used to measure physical, emotional, and social dimensions of health as well as school functioning. Question responses were used to generate scores from 0-100 (100 being the best quality of life) based on the PedsQLTM guidelines. The number of participants drops slightly for the school functioning result as not all participants are eligible to answer these school-related questions.

Collected over Cohort 1: study entry through final study visit (Week 16, premature discontinuation prior to Week 16, final long-term safety follow-up visit, or Cohort 2 entry) Cohort 2: study entry through final study visit (Week 96, premature discontinuation prior to Week 96, final long-term safety follow-up visit, or final safety extension visit). Non-serious events are listed at a 0% frequency threshold.
