TRIAL DESCRIPTION
Public title Point-of-care Urine Monitoring of Adherence (PUMA): Testing a Real-Time Urine Assay of Tenofovir in PrEP
Official scientific title Pilot trial to examine the feasibility, acceptability, and impact on longer-term adherence of an intervention using a new urine-based tenofovir adherence assay
Brief summary describing the background and objectives of the trial Worldwide expansion of pre-exposure prophylaxis (PrEP) will be critical to ending the HIV epidemic. The original PrEP clinical trials showed us that 1) adherence is critical to effectiveness; 2) daily PrEP adherence was difficult to maintain, especially among women not in serodiscordant relationships; 3) objective adherence measures (e.g. measuring PrEP drug levels) are more reliable than self-reported adherence, and 4) real-time monitoring of PrEP drug levels with feedback to the patient could improve subsequent adherence. Objective measures of PrEP adherence, especially point-of-care measures that enable real-time assessment, intervention, and feedback, will be important for both interpreting and optimizing effectiveness during PrEP implementation. Our group has developed a novel point of care urine-based measure of PrEP adherence which has been validated among HIV-uninfected volunteers who were administered TDF/FTC. The test has now been developed into a lateral flow assay (LFA), allowing real-time monitoring. This test is cheap, easy to perform and can be done at the point-of-care. However, this tool has not yet been tested among participants on PrEP in a trial to see if real-time monitoring of adherence using the urine assay is feasible, acceptable and motivates better adherence in the future. Aim #1: To perform a pilot randomized controlled trial (RCT) in Kenya to establish the impact of real-time adherence monitoring/feedback via the urine POC TFV immunoassay on increasing PrEP adherence over time (as established by a long-term metric of adherence using hair levels). Aim #2: To assess the acceptability of the urine-based test to participants and feasibility administering the test for research healthcare providers. Specifically, we seek to understand user and provider experiences, preferences, barriers, and facilitators related to POC urine tenofovir adherence testing among women receiving PrEP and providers after the pilot trial.

Experimental Group Point of care Urine Assay of Tenofovir in PrEP Tenofovir drug levels in urine will be tested real-time every 3 months 12 Months women not in serodiscordant couples on PrEP in Kenya will be randomized to standard of care adherence counseling (n=50) vs real-time adherence feedback using information from the POC urine assay (n=50). The effect of the feedback on long-term adherence over time measured via tenofovir (TFV) levels in hair samples will be assessed. 50
Control Group Standard of Care adherence counselling Adherence counselling will be done every 3 months 12 Months Women not in serodiscordant couples on PrEP in Kenya will be randomized to standard of care adherence counseling (n=50) vs real-time adherence feedback using information from the POC urine assay (n=50).

OUTCOMES
Type of outcome Outcome Timepoint(s) at which outcome measured
Primary Outcome Trial outcomes will be acceptability to participants, feasibility for healthcare providers, and long-term metrics of PrEP adherence as assessed via TFV concentrations in hair samples. At months 3, 6, 9, and 12 for all participants, the study team will collect urine, blood for plasma, whole blood for dried blood spots, and hair samples.
Secondary Outcome HIV-1 incidence will be measured but is expected to be low (0.2% per year in the Partners Demonstration Project, and 0% for those taking PrEP) and the study would need to be considerably larger to be powered to assess incident HIV-1 (and unnecessary, given the established relationship between PrEP adherence and efficacy). We will assess genotypic HIV-1 resistance among any seroconverters and provide that information to the healthcare providers assuming responsibility for the patient’s routine HIV care. At months 3, 6, 9, and 12 for all participants, the study team will collect urine blood for plasma, whole blood for dried blood spots, and hair samples.
