Conditions
HIV-1-infection

Device: PrEPsmart mobile app
Registration Number

Brief Summary

This is a pilot study to assess the feasibility, acceptability, and preliminary effectiveness of pre-exposure prophylaxis (PrEP)smart among cisgender sexual minority males (SMM) taking on-demand PrEP over a 6-month period.

Upon project completion, the investigators will have developed a highly innovative tool to support men who have sex with men (MSM) using on-demand PrEP ready for testing in a larger efficacy trial

Detailed Description

This study is designed to enroll a diverse population of English-speaking cisgender sexual minority males (SMM) in the United States. The study team will enroll up to 60 participants who are taking or are interested in taking on-demand pre-exposure prophylaxis (PrEP). Participants will be randomized 2:1 to receive (intervention arm) or not receive (control arm) the PrEPsmart app at enrollment. Participants will complete follow-up visits at 3 and 6 months.

Participants newly starting 2-1-1 PrEP will be seen at the Bridge HIV clinic (prescribed group), while those already on PrEP may be seen at the clinic or complete visits virtually (non-prescribed group). Although no restrictions are put on the racial/ethnic make-up of the study participants, the site will strive to enroll at least 50% African American or Latino SMM into this study. The study will also strive to enroll at least 30% of participants who are newly starting or restarting 2-1-1 PrEP. Upon project completion, the study team will have developed a highly innovative tool to support men who have sex with men (MSM) using on-demand PrEP ready for testing in a larger efficacy trial.

GroupInterventionDescription
PrEPsmart intervention (N=40)TruvadaParticipants will be randomized in a 2:1 ratio to the intervention (N=40) For the pre-exposure prophylaxis (PrEP)smart intervention group, a study clinician will perform a medical history and limited physical exam to confirm eligibility to enroll in the study, a 4th generation rapid Human immunodeficiency virus (HIV) test will be performed, and labs drawn for creatinine, sexual transmitted infection (STI) testing (Neisseria gonorrhoeae/Chlamydia trachomatis (GC/CT)), syphilis), and hepatitis B testing. For participants newly starting 2-1-1 PrEP (PrEPsmart intervention group), study drug will be offered to participants to ensure that they will have access to PrEP during the study to be able to adequately test the app.

Primary Outcome Measures
NameTimeMethod
Acceptability of the PrEPsmart mobile app6 months

Acceptability will be measured using the Client Satisfaction Questionnaire (CSQ-8) adapted for use in PrEPsmart pilot. The study team will also assess interest in future use of the app at study completion.

Usability of the PrEPsmart mobile app6 months

Usability will be measured using the System Usability Scale (SUS) adapted for use in PrEPsmart pilot. A score \>50 (out of 100) on the SUS indicates the app is acceptable.

Secondary Outcome Measures
NameTimeMethod
To compare PrEP coverage of sex acts as measured by weekly urine tenofovir test strips among SMM in the PrEPsmart vs. control arms6 months

PrEP coverage will be primarily defined as self-reported sex acts in which the participant reported at least one pill taken within 24 hours before sex and one pill taken within 24 hours after sex, as defined in the Ipergay study. Additionally, the study team will conduct an analysis in which weekly PrEP dosing is confirmed by having a detectable TFV urine test within 7 days of reported sex.

To compare switching of PrEP regimens among SMM in the PrEPsmart vs. control arms6 months

The proportion of participants who switch from on-demand PrEP to daily PrEP (or another regimen, e.g.

injectable PrEP) will be calculated and compared between arms using chi-square tests.

To compare rates of PrEP discontinuation among SMM in the PrEPsmart vs. control arm6 months

PrEP discontinuation and retention rates will be calculated, with 95% binomial confidence intervals, and compared between arms using log-binomial models. The study team will also estimate and compare time to discontinuation using Kaplan Meier methods and the log-rank test, accounting for censoring by end of study or dropout.

Elicit feedback on areas for improvement for PrEPsmart to guide further app refinement6 months

Ideas for improvement of PrEPsmart elicited through exit interviews will be tabulated, discussed with the protocol team, and prioritized for development.
