The SUSTAIN 2 Study - SUStained HIV Treatment for Adherence After Interruption in Care

Sponsor

Brigham and Women's Hospital

Enrollment

310 participants

Start Date

Nov 14, 2025

Study Type

INTERVENTIONAL

Conditions

Human Immunodeficiency Virus

Summary

The goal of this clinical trial is to learn if the DSD model (SUSTAIN-DSD) is effective in improving participants HIV treatment adherence. The main questions it aims to answer are: * Does the SUSTAIN-DSD intervention significantly improve participants' treatment adherence and increase rates of viral suppression? * Does the SUSTAIN-DSD intervention help retain people in care? * Does SUSTAIN-DSD intervention help reduce the length of treatment interruptions? * for 24 months, Participants will either receive the SUSTAIN-DSD intervention (i.e. be enrolled in an adherence club where the participants will pick up 6-months of ART medication and have the option to use peer support and additional counseling), and or enhanced standard of care (i.e. visit the clinic for treatment and participate in optional counseling sessions). Blood will be drawn from the participants at the adherence club visits for viral load tests at baseline and every 12 months. \- Participants will take part in interviews to discuss the participants' experience with the SUSTAIN-DSD intervention.

Eligibility

Min Age: 18 Years

Plain Language Summary

Simplified for easier understanding

This study (SUSTAIN 2) is testing a patient support program designed to help people living with HIV in Cape Town, South Africa, who have fallen out of regular HIV care or whose virus is detectable, to re-engage with treatment and maintain viral suppression on a simpler, community-based care model. **You may be eligible if...** - You are 18 or older and living with HIV - You are on a dolutegravir-based first-line antiretroviral therapy (ART) regimen - You have had a gap in care (missed an appointment by more than 28 days) or a detectable viral load in the past year - You are able to provide informed consent **You may NOT be eligible if...** - You have tuberculosis, epilepsy, or another condition that requires regular clinic-based monitoring - You are pregnant at enrollment and using the antenatal care system - You have been consistently adherent with an undetectable viral load for the past year - You plan to leave Cape Town permanently within the next 2 years Talk to your doctor to see if this trial is right for you.

Interventions

BEHAVIORALSUSTAIN-DSD

Participants randomized to SUSTAIN-DSD will be enrolled into an Adherence Club and will have 6 months of ART dispensed through a pre-packed dispensing service. Participants may choose to use the decentralized pick-up point solely for medication retrieval or may opt into the peer-support aspect of the Clubs by attending the group session of up to 30 PWH, who will meet once every 6 months in a safe space (e.g., clinic meeting room, church, or local library). At 6 months, 12 months, and every 12 months thereafter, a visiting nurse will draw a blood specimen for viral load. Optional process uptake will be recorded. Participants with a raised viral load will be called and offered enhanced adherence counselling; then recalled for a repeat viral load in 3 months.

OTHEREnhanced (guideline-driven) Standard of Care (E-SoC)

As per current SA ART guidelines, all patients who are \>28 days late for a scheduled visit are offered enhanced adherence counselling (EAC) at reengagement and restarted on ART. Patients who are \>90 days late also have blood drawn for a CD4 count to test for advanced HIV disease. Individual clinic visits occur every 3 months, with 3-month ART dispensing. VL testing is repeated 3 months after restart, then at 12 months and annually there-after, if suppressed. These visits will be managed by clinic staff (nurse or doctor). EAC is a single counselling session delivered by a lay counsellor. The study team will ensure all SoC processes are complete as per the guidelines; and reported to the COCT team as appropriate.
