Outcomes of the PLHIV With Suboptimal Viral Suppression to Injectable Long-acting Antiretrovirals
- Conditions
- HIV-1-infectionNon-Adherence, Medication
- Interventions
- Drug: cabotegravir/rilpivirine (600mg/ 900mg)Drug: Antiretroviral Combinations
- Registration Number
- NCT06507059
- Lead Sponsor
- Chang Gung Memorial Hospital
- Brief Summary
This study aims to determine whether people living with HIV (PLHIV) with suboptimal medical adherence can achieve better viral suppression with long-acting antiretrovirals (LA) compared to all-oral antiretrovirals.
- Detailed Description
This is an open-label, multi-center, randomized, active-controlled, superiority trial on 40 adult subjects who had been diagnosed to have HIV infection for at least 12 months before enrollment but with suboptimal viral suppression despite antiretroviral treatment (ART), with the latest HIV-1 viral load ≥ 200 copies/mL. Participants' eligibility will be assessed through a review of their medical records, and individuals with established resistance to cabotegravir or rilpivirine will be excluded. Enrolled participants will then be randomized 1:1 to either "Delayed Switch to LA Treatment Group" or "Immediate LA Treatment Group" on enrollment. The "Delayed Switch to LA Treatment Group" will also switch to LA on week 24. The proportion of participants with HIV-1 RNA \<200 copies/mL at week 24 in the two study groups will be compared. Psychologic assessments including self-stigma and depression assessment will also be performed on day1, at week 24 and week 52.
