Study summary

This non-randomized, open-label study will address the following research aims in People who inject drugs (PWID):

  • To assess the feasibility and acceptability of the Expanding PrEP Implementation in Communities of PWID (EPIC-P) intervention among high-risk PWID.
  • To determine the preliminary efficacy of the EPIC-P intervention in terms of increasing adherence to PrEP and primary HIV prevention among high-risk PWID.
Read the detailed description

A non-randomized, open-label design will be utilized to test the feasibility, acceptability, and preliminary efficacy of the Expanding PrEP Implementation in Communities of PWID (EPIC-P) intervention among high-risk people who inject drugs (PWID) with opioid dependence (N=100). Since the aim of this pilot study is to establish whether the EPIC-P intervention is feasible/acceptable among at-risk PWID in a community-based setting, proposed is a non-comparative design. With the hopes to target PWID who are not linked with existing harm reduction services, proposed is to recruit participants using respondent driven sampling (RDS), a chain referral method with demonstrated success in recruiting hard-to-reach populations. Initial RDS participants, called "seeds," will be carefully recruited from the community where the study team leadership have built a well-established relationship. Participants enrolled in the study will be assessed at baseline and will be followed for 9 months (with follow-up assessments at 3- and 6-months) by trained research assistants. Importantly, structured interviews will be conducted at follow-up visits to examine the barriers and facilitators and feedback about optimal implementation of the EPIC-P intervention.

    EPIC-P

    Participants will enroll in a bio-behavioral intervention aimed at preventing HIV transmission in people who inject drugs.

    Other: EPIC-P

Interventions

  • OtherEPIC-P

    EPIC-P is a brief, bio-behavioral intervention based on the information-motivation-behavioral skills (IMB) model framework, which integrates i) a biomedical component (i.e., PrEP), ii) behavioral components (i.e., drug- and sex-related primary HIV prevention), and iii) mHealth technology (i.e., text messaging PrEP reminders).

What researchers measure

Primary outcomes

  1. Retention Rate

    To determine feasibility, the rate of enrolled participants that are retained through the study will be assessed.

    Time frame: Up to 6 months

Secondary outcomes

  1. Acceptability

    The acceptability will be assessed using a series of eight items acceptability rating profile. We will use a 5-point Likert scale (0= strongly disagree to 4= strongly agree) to rate the extend to which they agreed with each acceptability statement. A mean intervention acceptability score will be calculated with higher values indicating greater acceptability.

    Time frame: Up to 6 months

  2. PrEP Adherence VAS

    Adherence to PrEP will be assessed using a visual analog scale (VAS).

    Time frame: Up to 6 months

  3. PrEP Adherence Pharmacy

    Adherence to PrEP will be assessed by monitoring the pharmacy refills of participants.

    Time frame: Up to 6 months

  4. PrEP Adherence DBS

    PrEP Adherence will be objectively assessed using dried blood spot (DBS) testing for tenofovir levels.

    Time frame: Up to 6 months

  5. HIV Incidence

    HIV incidence will be tracked in participants through testing up to 6 months.

    Time frame: Up to 6 months
