About this study
Official title: Peer-driven Intervention Promoting PrEP Uptake Among African American and Hispanic/Latino MSM
The objective of this study is to develop an effective peer-driven intervention (PDI) approach and assess its feasibility and efficacy on pre-exposure prophylaxis (PrEP) uptake among men who have sex with men.
Read the detailed description
This proposed study aims to assess the effect of a peer-driven intervention (PDI) on promoting pre-exposure prophylaxis (PrEP) uptake among African American (AA) and Hispanic/Latino men who have sex with men (MSM). PDI is based on respondent-driven sampling (RDS) or snowball sampling. PDI is a chain referral approach and includes both peer referral and peer education. Index peers will be purposefully sampled to reflect the diversity of our study population through local clinics, community organizations, and online. Index peers will receive a four-hour formal training about PrEP and HIV, educate members of their social network, and encourage them to initiate PrEP. Each index peers will be given three referral coupons. Referred peers will schedule a research visit to complete a short survey and then be referred to the local PrEP clinic if they are interested in starting PrEP. These referred individuals will also serve as index peers for the following wave of recruitment. We expect to achieve a robust sample of AA and H/L MSM within six waves of recruitment as peers will educate and recruit study participants through their social networks.
Given the nature of RDS, the study design will include a concurrent non-randomized control group, which will be recruited using venue-based sampling (e.g. gay dance clubs, bars, and social organizations). This has been used in previous RDS studies as an appropriate study design and comparison group. We will identify appropriate venues that AA and H/L MSM frequent using one-to-one qualitative interviews in Specific Aim 1. Research staff will visit these venues at specific times to recruit AA and H/L MSM. MSM who are willing to participate in this study will receive PrEP and HIV education offered by research staff and complete a short survey during outreach. Individuals who are interested in PrEP uptake will be referred to the PrEP clinic. All study participants, regardless of PrEP status (initiated or not initiated), will be followed for six months. Each individual will complete three visits, including baseline, three-month, and six-month follow-ups.
This study has two independent arms. Our primary outcome is PrEP uptake, which is defined as a binary variable (Yes vs. No). We will calculate the study power using the method for two independent proportions power analyses. Our local STD clinic data shows only 8% of AA and H/L MSM have used PrEP and we will assume that 8% of AA and H/L MSM recruited through venue-based sampling will initiate PrEP. We expect to observe at least a 14% increase in PrEP uptake in the PDI group. To have 80% of power (Type I error =0.05), we will recruit 100 participants (N=100, 50 AA, and 50 H/L MSM) in each group.
PrEP uptake measured by receiving a prescription for the medication and filling a prescription at a pharmacy will be treated as time-to-event variables. We will perform survival analysis techniques (Kaplan-Meier models and Cox proportional hazards models) to assess the effect of the PDI on PrEP initiation. Self-reported PrEP adherence and drug concentration level (Yes vs. No) will be treated as binary variables and multivariate logistic regression will be performed.

Peer-driven interventionBehavioural
This peer-driven intervention (PDI), modified based on respondent-driven sampling (RDS) or snowball sampling, is a "chain referral" approach. Index peers will be purposefully selected to reflect the diversity of African American (AA) and Hispanic/Latino (H/L) men who have sex with men (MSM) and are required to take a formal training about pre-exposure prophylaxis (PrEP) and HIV. These index peers will educate members of their social networks and encourage them to initiate PrEP. Those referred peers will schedule an appointment to complete a short survey and will be referred to our PrEP clinic if they are interested in PrEP uptake. The referred peers will serve as index peers for the following wave of recruitment. It is expected to achieve a robust sample of AA and H/L within six waves of recruitment. This PDI approach is potential to engage AA and H/L who are most at risk of HIV acquisition in PrEP uptake and could contribute to reducing the concentrated HIV epidemic.
| Study group | Role | What they receive |
|---|---|---|
| PDI group | Experimental | In this group, participants will receive education about HIV and pre-exposure prophylaxis (PrEP) and be referred to our study by peer educators. Referred participants will have free PrEP counseling and receive referrals if interested. We will follow up at three and six months and check participants' PrEP status. Receives: Behavioral: Peer-driven intervention |
| Control group | No intervention | In the control group, participants do not receive any education from peers and will be directly recruited by research assistants from venues (e.g. gay bars, LGBTQ communities, LGBTQ events, and social media advertisements). Participants will receive PrEP counseling and referral if interested. We will follow up at three and six months and check participants' PrEP status. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pre-exposure Prophylaxis (PrEP) Uptake
Participant self-report of having initiated PrEP medication at any point between the baseline visit and the 6-month follow-up. Data represent the number of participants who provided a 'Yes' response to the assessment question: 'Have you started taking PrEP since your last visit?
Measured: 0-6 months
Number of Participants With PrEP Persistence
The number of participants who remained on PrEP medication without a gap of more than 30 days throughout the 6-month study period, as reported during follow-up interviews.
Measured: 0-6 months
Pre-exposure Prophylaxis (PrEP) Adherence
Participant adherence to the prescribed PrEP regimen over the 30 days prior to the 6-month follow-up visit, measured via self-report. Adherence was calculated based on the frequency of doses taken per week. Participants were considered adherent if they reported taking at least 4 pills per week, which is the threshold associated with high levels of protection against HIV acquisition.
Measured: 30 days prior to 6-month follow-up visit

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 19 May 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pre-exposure Prophylaxis (PrEP) Uptake (time frame: 0-6 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 May 2026.
