About
The long-term goal of this research is to create an effective and sustainable program to support retention in PrEP care and PrEP adherence among 18-29 year old men who have sex with men (MSM). To reach this goal, we will develop and pilot test a mobile intervention tailored to young MSM, called PrEP iT! Primary aims include:
Aim 1: Develop the PrEP iT! mobile intervention through focus groups with young MSM and refine iterations through input from a community advisory board (CAB).
Aim 2: Conduct a pilot randomized controlled trial to assess the feasibility, acceptability and preliminary impact of the PrEP iT! intervention for young MSM.
Full description
Study Design:
We propose to evaluate the feasibility, acceptability and preliminary impact of PrEP iT! in a pilot RCT (n=80). Young men who have sex with men (YMSM) recently (re)initiating PrEP will be randomized to receive either PrEP iT! plus usual care or usual care alone, and followed for 6 months with assessments at baseline, and 3- and 6-months.
PrEP iT! will use open source software that conforms to current programming standards, and can be used across all devices (desktop, laptop, smartphone, and tablet) to ensure sustainability. PrEP iT! will be developed from feedback from PrEP-using YMSM through focus groups and a community advisory board (CAB). PrEP iT! is grounded in the Information, Motivation, and Behavioral Skills model, and also draws from a model of technology adoption.
PrEP iT! intervention components are:
- PrEP Adherence, PrEP Appointment, and Sexual Activity Self-Monitoring
- Tailored feedback on PrEP adherence/non-adherence
- PrEP and sexual health information tailored for YMSM
- Text message reminders for PrEP adherence and healthcare appointments
- An "ask the expert" feature
Control arm participants will receive usual PrEP care only. Locally this entails, clinic visits every 3 months in the initial period following PrEP initiation, including HIV/STI screening and laboratory toxicity testing.
Study Sample:
Recruitment will be stratified by age in a 1:1 ratio (i.e., n=40 per group) of 18-24 and 25-29 year olds, and will reflect 50% Black and/or Hispanic YMSM participation. This will allow us to explore subgroup differences (e.g., by age and race/ethnicity) for PrEP iT! to better inform future trials.
Recruitment and Clinical Sites:
Participants will be recruited from two clinics in Minneapolis that provide PrEP care. The clinical sites include the HIV clinic at Hennepin Healthcare (HH) and the Hennepin County STD clinic. We will recruit and enroll study participants concurrent with their PrEP clinical visits when possible.
Participants will be recruited in four ways: a) PrEP clinic patients who are new or returning to care (i.e., are not currently receiving PrEP) will be identified by clinic staff and referred to research coordinators on the day of their clinic visit when possible; b) flyers will be hung in PrEP clinics and other HIV/AIDS NGO service organizations within the Twin Cities; and c) the study team will engage and solicit referrals from other community HIV/AIDS NGO with focused PrEP and prevention campaigns.
Enrollment, Randomization, and Follow-up Visits:
Study candidates will undergo a separate screening visit with a brief questionnaire at/after PrEP clinic visits. Participants will have a rapid HIV test as part of usual care. Persons whose test positive for HIV will be referred for same-day evaluation and care. Participants are randomized 1:1 to either the intervention (PrEP iT! + usual care) or control (usual care) arm. The randomization sequence will be stratified by age (18-24 v. 25-29 yrs) and use blocks of ten.
After informed consent, participants will complete a computer-assisted baseline survey. All participants will be provided usual PrEP educational information encouraged to attend their regular healthcare visits. Participants randomized to the treatment arm (PrEP iT! + usual care) will be guided through setting up their user account and user profile, provided with basic training on how to navigate and use intervention components, and given the opportunity to ask questions. YMSM in the treatment arm will have immediate access to PrEP iT! after the initial visit.
YMSM will undergo a 3- and 6-month follow-up assessment, with multiple reminders sent to participants prior to each visit. The 3- and 6-month stud procedures include completing a short computerized assessment, and submitting a dried blood spot specimen for the TFV-DP analyses. Study data will also be collected from the month 3 and month 6 healthcare visits that include laboratory and clinical data generated routinely as part of standard PrEP care (e.g., testing for HIV Ab and other STIs). We anticipate that most HIV tests results data will be extracted from participant's medical record to confirm their HIV-negative status. In the event that we must conduct an HIV test (e.g., we are unable to extract that from the medical record or if there is an expressed concern that the participant's HIV status has changed), they will be conducted at the Hennepin Healthcare clinical laboratory, using standard clinical assays (we use the HIV Ab/Ag combination test for diagnosis). This information would be captured in our CRFs via REDCap, and this information will be securely transferred to SDSU but would be via a de-identified file.
Study retention protocols involve the use of multiple contact methods, including telephone calls, text messages and e-mail reminders. We anticipate no more than 20% attrition.
Exit Interviews: A random subset of participants randomized to the PrEP iT! arm will be asked if he would be willing to participate in 30-60 minute exit interview to assess a) his experience in the intervention, b) suggestions for modifications to the existing interface, c) suggestions for new features; and d) and changes to the study procedures. Recruitment for exit interviews will entail sufficient numbers for the goal of achieving ten men completing the exit interview.
