Clinical Trial Summary

Antiretroviral therapy (ART) has significantly decreased the morbidity and mortality of HIV infection. However, adherence challenges in taking daily oral ART persist. A retrospective cohort study across 31 countries from 2010-19 reported that only 65% of people with HIV (PWH) on ART exhibited virologic suppression (VS) three years after starting ART;1 the rate of VS in South Africa among PWH on ART is 60-65%. Adherence barriers span individual and structural factors, such as stigma, recall difficulties, housing and/or food insecurity, mental illness, substance use, transportation, stock-outs, and other factors that vary by country and population. Adherence interventions can benefit from direct objective adherence monitoring. Pharmacologic metrics of adherence assess drug levels in plasma, dried blood spots, hair (a metric our group pioneered) or urine and predict outcomes more accurately than self-reported adherence. However, most of these metrics preclude real-time assessment, requiring expensive laboratory equipment and trained laboratory personnel. Thus, few adherence interventions have successfully incorporated objective metrics, likely due to laboratory and shipping delays. A low-cost (<$2/test) point-of-care adherence metric - developed by our group - should allow for real-time biofeedback and improve the impact of metric-driven adherence interventions.

Description:

This is a randomized hybrid type 1 effectiveness study design to assess the factors related to implementation of a point-of-care urine TFV assay test into routine HIV clinical care. We plan to recruit a total of 500 adults living with HIV who received primary HIV care from one of the selected study clinics in BCM, Eastern Cape. Individuals who have been prescribed ART for at least 6 months who have not achieved VS will be randomized in a 1:1 fashion at the baseline visit to the intervention arm vs. the SoC arm. Total duration of the study is 18 months from the time of enrollment.

Eligibility

Inclusion Criteria:

Aim 1: Individuals =16 years of age at the initial screening visit living with HIV, prescribed ART for at least three months, and are not virally suppressed. Aim 2: Same as Aim 1 for the acceptability survey and in-depth interviews. HIV care providers in the selected clinic sites for the feasibility survey and in-depth interviews. Aim 3: Same as Aim 1 for the cost-effectiveness study.

Exclusion Criteria:

• Currently enrolled in another ART adherence intervention
• Patients on ART regimen that does not include Tenofovir
• HIV care providers from non-study sites Failure to provide written consent

Related Conditions & MeSH terms

• ART Adherence

Intervention

Behavioral:
• POC urine assay informed enhanced ART adherence counselling for viral suppression
Collect urine on intervention participants and screen for presence of TFV. Feedback will be provided to the participant based on the results on their ART adherence with provision of enhanced ART adherence counseling for viral suppression.
