Pre-exposure Prophylaxis (PrEP) for Health (PrEP)
Efficacy of a Community-based PrEP Uptake Intervention for People Who Inject Drugs (PWID) in the US Northeast
Study Overview
Status
Detailed Description
The overall goal of this proposal is to evaluate the efficacy of the "PrEP for Health" navigator delivered behavioral intervention in improving PrEP uptake (via medical/pharmacy records), post-treatment PrEP adherence (assessed at 3 months via drug levels in hair), and longer-term PrEP adherence (assessed at 6 and 12 months via drug levels in hair) among PWID in SSPs. Eligible PWID (n=200 total; 100 recruited from each study site) will be equally randomized to an active PrEP for Health intervention arm (n=100) or a Standard of Care control condition (n=100). Assessments will be conducted at baseline and 1, 3, 6, and 12 months after randomization.
We hypothesize that brief, multi-component behavioral intervention sessions with ongoing support delivered by trained PrEP Navigators within Syringe Service Programs (SSPs) will improve PrEP uptake, adherence, and long-term adherence in PWID by increasing HIV and PrEP knowledge (including alleviating concerns about side effects), increasing HIV risk perceptions and PrEP interest and motivation, improving PrEP use self-efficacy and behavioral skills, and reducing structural barriers over time. Based on our formative research, we also hypothesize that the strength of intervention effects may differ by key individual characteristics (age, gender, baseline sexual risk, polysubstance, and stimulant use).
This is a randomized control trial (RCT). Participants will be recruited via outreach specialist at SSP sites and during routine community outreach practices of the organizations. After eligibility confirmation and baseline assessments, participants will be randomized to one of two study arms: 1) Standard of Care (SOC) Control Condition: as routinely provided through the SSP study sites, participants will receive information and services according to routine practice and a brief video that describes what PrEP is and how it works to prevent HIV via sexual and injection transmission; 2) "PrEP for Health" Intervention Condition: a trained PrEP Navigator will deliver a manualized PrEP uptake and adherence intervention in private counseling rooms at SSPs followed by 3 months of additional PrEP navigation support through in-person, phone, and text interactions as needed. Participants will complete a total of four follow-up visits over a 12-month period. Participants who initiate PrEP will have a hair sample collected at 3-, 6-, and 12-month visits. All participants will receive a rapid HIV screening test at 12-month follow-up.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: PrEP for health
Participants in the PrEP (pre-exposure prophylaxis) for health arm will receive theory informed HIV and PrEP education, motivational interviewing, problem-solving and planning, and ongoing patient navigation.
|
Navigators will deliver Social Cognitive Theory-informed HIV and PrEP education.
Bachelors-level PrEP Navigators who are trained in motivational interviewing (MI) will use MI to promote the behavioral intervention.
Bachelors-level PrEP Navigators will assist participants with problem-solving and planning.
Ongoing PrEP navigation support to promote participants' initial and continued engagement with PrEP clinics affiliated with the two study sites
A brief video that describes what PrEP is and how it works to prevent HIV via sexual and injection transmission will be shown to participants.
|
Active Comparator: Standard of care
Participants in the standard of care arm will receive PrEP information and referrals.
|
A brief video that describes what PrEP is and how it works to prevent HIV via sexual and injection transmission will be shown to participants.
Study staff will provide basic information about PrEP and referrals to PrEP clinicians.
