NCT06631365

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

Outcome Measures

Primary Outcomes (2)

  • Acceptability of the PrEPsmart mobile app

    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.

    6 months

  • Usability of the PrEPsmart mobile app

    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.

    6 months

Secondary Outcomes (4)

  • To compare PrEP coverage of sex acts as measured by weekly urine tenofovir test strips among SMM in the PrEPsmart vs. control arms

    6 months

  • To compare switching of PrEP regimens among SMM in the PrEPsmart vs. control arms

    6 months

  • To compare rates of PrEP discontinuation among SMM in the PrEPsmart vs. control arm

    6 months

  • Elicit feedback on areas for improvement for PrEPsmart to guide further app refinement

    6 months

Study Arms (2)

PrEPsmart intervention (N=40)

EXPERIMENTAL

Participants 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.

Device: PrEPsmart mobile appDrug: Truvada

control (N=20)

NO INTERVENTION

For the non-prescribed group, study staff will request documentation of an HIV-negative test within the last 3 months OR evidence of pre-exposure prophylaxis (PrEP) prescription within the last 6 months from medical records or pharmacy/provider communication. Additionally, study staff will confirm via self-report that the participant's 2-1-1 PrEP use will be clinically monitored by another clinician or clinic for the duration of the study. Any individual with a positive HIV test will have a confirmation test sent to the lab and be referred immediately for HIV care and initiation of treatment. For participants already on PrEP (control group) may choose to continue to use their own supply of Truvada (tenofovir disoproxil fumarate/emtricitabine, or TDF/FTC).

Interventions

The PrEPsmart mobile app is an innovative and comprehensive app to support sexual minority men (SMM) using on-demand pre-exposure prophylaxis (PrEP) or daily PrEP. The PrEPsmart app consists of the following components: 1. PrEP 211 dosing/sex diary and reminders 2. Feedback on PrEP protection levels 3. Quick tips 4. Bi-directional secure messaging

PrEPsmart intervention (N=40)

Combination medication used in Human immunodeficiency virus (HIV) prevention, it blocks virus pathways to infection.

Also known as: Emtricitabine, Tenofovir disoproxil fumarate
