Description

Summary

The purpose of this study is to compare the efficacy, safety, and durability of two different strategies to treat participants with a history of sub-optimal adherence and control of their HIV infection: long-acting (LA) antiretroviral therapy (ART) and all-oral standard of care (SOC).

Official Title

A Phase III Study to Evaluate Long-Acting Antiretroviral Therapy in Non-Adherent HIV-Infected Individuals

Details

This study will compare the efficacy, safety, and durability of two different strategies to treat participants with a history of sub-optimal adherence and control of their HIV infection: long-acting (LA) antiretroviral therapy (ART) with rilpivirine (RPV) LA and cabotegravir (CAB) LA versus all-oral standard of care (SOC).

The study includes four steps. In Step 1, participants will receive a SOC oral induction regimen consisting of an ART regimen that involves at least 3 drugs for 24 weeks. Participants who achieve milestones will receive conditional economic incentives at Weeks 2, 4, 8, 12, 16, and 20.

In Step 2, eligible participants will be randomized to receive either oral RPV + oral CAB for 4 weeks followed by RPV-LA + CAB-LA every 4 weeks for 48 weeks or to continue on SOC for 52 weeks.

At the completion of Step 2, eligible participants randomized to SOC will have the option to register to Step 3 and receive LA ART, which includes oral RPV + oral CAB for 4 weeks followed by RPV-LA + CAB-LA every 4 weeks for 48 weeks. Participants already receiving RPV-LA + CAB-LA in Step 2 will continue on this regimen in Step 3 for 52 weeks.

Eligible participants will enter Step 4 and be followed for 52 weeks on locally sourced oral ART.

Participants will be followed for up to a total of 180 weeks. Study visits, which will occur throughout the study, may include physical examinations; blood, urine, and hair collection; liver function tests; questionnaires; and an electrocardiogram (ECG).

Eligibility

For people ages 18 years and up

Step 1 Inclusion Criteria

  • HIV-1 infection, documented by any licensed rapid HIV test or HIV enzyme or chemiluminescence immunoassay (E/CIA) test kit at any time prior to study entry and confirmed by a licensed Western blot or a second antibody test by a method other than the initial rapid HIV and/or E/CIA, or by HIV-1 antigen, plasma HIV-1 RNA viral load.
  • NOTE: The term "licensed" refers to a FDA-approved kit, which is required for all IND studies.
  • WHO (World Health Organization) and CDC (Centers for Disease Control and Prevention) guidelines mandate that confirmation of the initial test result must use a test that is different from the one used for the initial assessment. A reactive initial rapid test should be confirmed by either another type of rapid assay or an E/CIA that is based on a different antigen preparation and/or different test principle (e.g., indirect versus competitive), or a Western blot or a plasma HIV-1 RNA viral load.

  • Alanine aminotransferase (ALT) less than or equal to 3 x upper limit of normal(ULN)
  • Creatinine Clearance (CrCl) greater than or equal to 50 mL/min estimated by Cockcroft-Gault
  • NOTE: A calculator for estimating the CrCl can be found at www.fstrf.org/ACTG/ccc.html.
  • For women of reproductive potential, negative serum or urine pregnancy test with a sensitivity of less than or equal to 25 mIU/mL at screening. This will be repeated again at study entry.
  • NOTE: Female participants are considered to be NOT of reproductive potential if:1) they have had amenorrhea for at least 12 consecutive months prior to study entry ((i.e., who have had no menses within 12 months prior to study entry), and have a documented follicle-stimulating hormone (FSH) greater than 40 IU/mL; OR 2)an FSH level is not available, but they have had 24 consecutive months of amenorrhea (in the absence of medications known to induce amenorrhea); OR 3) they report having undergone surgical sterilization (e.g., hysterectomy, or bilateral oophorectomy, or bilateral tubal ligation/hysteroscopic tubal occlusion).
  • Contraception requirements
