About this study

Official title: Enhancing HIV Pre-Exposure Prophylaxis (PrEP) by Targeting Hazardous Alcohol Use and Concurrent Conditions

The present investigation entails a pilot randomized controlled trial to explore whether a stand-alone, alcohol-reduction, brief intervention (with a module on substance use and depression) would be feasible, acceptable, and potentially efficacious within the context of HIV pre-exposure prophylaxis (PrEP) treatment.

Read the detailed description

Although HIV pre-exposure prophylaxis (PrEP) is an effective tool that can help prevent the acquisition of HIV, its degree of effectiveness has been shown to be linked to a number of key behaviors, including treatment adherence, attendance in follow-up care, and the concurrent use of condoms. Hazardous alcohol consumption has the potential to contribute to suboptimal PrEP adherence, poor retention in PrEP care, and condomless sex/sexually transmitted infections (STIs); and its impact on these PrEP-related behaviors may also become exacerbated in the presence of concurrent issues such as substance use and depression, thus reflecting a potential syndemic effect. The present investigation entails a pilot randomized controlled trial in which 120 hazardous drinking, PrEP-prescribed men who have sex with men (MSM) will be randomly assigned to receive either a tablet-based, alcohol-reduction brief intervention or treatment-as-usual. Participants assigned to the former condition for whom substance use- and/or depression-related concerns are identified will additionally be provided with links to relevant supportive resources. Feasibility and acceptability of the intervention will be examined. Furthermore, biomarker testing and self-report electronic surveys at baseline, 3-months, and 6-months will be employed to assess the preliminary impact of the intervention on alcohol use, PrEP adherence, retention in PrEP care, and the engagement in condomless sex/STI acquisition.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Alcohol-focused brief interventionBehavioural

    The primary intervention component is the Check Your Drinking (CYD) intervention - an electronically-delivered brief intervention designed to assess and provide personalized feedback regarding the quantity, frequency, and severity of one's alcohol consumption. Additionally, intervention condition participants who are identified as having a concurrent substance use concern or who may be experiencing depression will receive information about local resources that can assist with such concerns.

Study groups in NCT05097430
Study groupRoleWhat they receive
Alcohol-focused brief interventionExperimentalIntervention arm participants will be provided with an electronically-delivered, personalized drinking feedback report that compares their drinking with other Canadian males of the same age. This report also includes other relevant feedback, including an assessment of severity of alcohol use, and it provides recommendations for safe levels of alcohol consumption.
Receives: Behavioral: Alcohol-focused brief intervention
Treatment as usualNo interventionTreatment as usual (TAU) participants will not receive the intervention.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Intervention Feasibility: Intervention Uptake

    Intervention uptake will be employed as an indicator of intervention feasibility. Intervention uptake will entail the proportion of eligible, hazardous drinking, PrEP-prescribed MSM who express a willingness to take part in the intervention trial.

    Measured: At study baseline

  2. Intervention Feasibility: Intervention Completion

    Intervention completion will be employed as an indicator of intervention feasibility. This outcome will entail the proportion of participants assigned to the intervention condition who complete the intervention module.

    Measured: At study baseline

  3. Intervention Acceptability

    Intervention acceptability will be assessed using a 13-item self-report measure that is comprised of two published scales (references shown below) and three items created by the investigators.

    Bauermeister JA, Pingel ES, Jadwin-Cakmak L, et al. Acceptability and preliminary efficacy of a tailored online HIV/STI testing intervention for young men who have sex with men: the Get Connected! program. AIDS Behav 2015 Oct;19(10):1860-74.

    NDA-NIH. NIMH Data Archive (NDA). 2020. Acceptability of Intervention, Intervention Appropriateness, and Feasibility of Intervention Measure. https://nda.nih.gov/data_structure.html?short_name=aimiamfim01

    Measured: At 6-months post-baseline

  4. Alcohol Consumption: Alcohol Use Disorders Identification Test (AUDIT)

    Self-report-based Alcohol Use Disorders Identification Test (AUDIT) scores will be compared across baseline, 3-months post-baseline, and 6-months post-baseline sessions. Babor TF, Higgins-Biddle JC, Saunders JB, Monteiro MG, World Health Organization. Dept. of Mental Health and Substance Dependence. The Alcohol Use Disorders Identification Test. Guidelines for Use in Primary Care. 2nd ed. Geneva: World Health Organization; 2001. A cut-off based on AUDIT-C (i.e., AUDIT-consumption) criteria categorizes the presence (i.e., AUDIT-C scores ≥4) or absence (i.e., AUDIT-C scores <4) of hazardous drinking. Minimum and maximum scores of the AUDIT-C are 0 and 12, respectively.

    Measured: Six months (i.e., baseline, 3-months post-baseline, 6-months post-baseline)

  5. Alcohol Consumption: Drinks Consumed in a Typical Week

    A single self-report question will ask "How many drinks containing alcohol do you have on a typical week when you are drinking?" Responses will be compared across baseline, 3-months post-baseline, and 6-months post-baseline sessions.

    Measured: Six months (i.e., baseline, 3-months post-baseline, 6-months post-baseline)

  6. Alcohol Consumption: Maximum Drinks on One Day in the Last 3 Months

    A single self-report question will ask "What is the greatest number of drinks you've had on one day in the last 3 months?" Responses will be compared across baseline, 3-months post-baseline, and 6-months post-baseline sessions.

    Measured: Six months (i.e., baseline, 3-months post-baseline, 6-months post-baseline)

  7. Alcohol Consumption: Phosphatidylethanol (PEth)

    PEth levels will be measured from dried blood spot (DBS) samples using liquid chromatography-tandem mass spectrometry to identify hazardous drinking. PEth will be compared across baseline, 3-months post-baseline, and 6-months post-baseline sessions.

    Measured: Six months (i.e., baseline, 3-months post-baseline, 6-months post-baseline)

Secondary outcomes (6)
  1. PrEP Adherence: 7-day ACTG-based Measure

    Self-reported adherence to PrEP will be assessed using a 7-day, PrEP-focused, ACTG-based adherence measure (the reference for the original, antiretroviral therapy (ART)-focused ACTG measure is shown below). 7-day adherence will be compared across baseline, 3-months post-baseline, and 6-months post-baseline sessions.

Patient Care Committee \& Adherence Working Group of the Outcomes Committe of the Adult AIDS Clinical Trials Group (AACTG) AIDS Care. 2000;12:255-266.

    Measured: Six months (i.e., baseline, 3-months post-baseline, 6-months post-baseline)

  2. PrEP Adherence: Past Month Visual Analog Scale (VAS)

    A self-report-based, PrEP-focused visual analog scale (VAS) will be used to assess PrEP adherence over the past month (the reference for the original, antiretroviral therapy (ART)-focused VAS is shown below). Past month adherence will be compared across baseline, 3-months post-baseline, and 6-months post-baseline sessions.

    Measured: Six months (i.e., baseline, 3-months post-baseline, 6-months post-baseline)

  3. PrEP Adherence: Tenofovir-diphosphate (TFV-DP) and Emtricitabine-triphosphate Concentrations

    Dried blood spots will be assessed for Tenofovir-diphosphate (TFV-DP) and emtricitabine-triphosphate concentrations using validated liquid chromatography tandem mass spectrometry. Concentrations will be compared across baseline, 3-months post-baseline, and 6-months post-baseline sessions.

    Measured: Six months (i.e., baseline, 3-months post-baseline, 6-months post-baseline)

  4. Retention in PrEP Care: PrEP Appointment Attendance

    Missed PrEP appointments across the six-month follow-up period will be identified through clinic chart extraction.

    Measured: Six-month follow-up period

  5. Condomless Sex

    The engagement in condomless anal sex will be assessed using a self-report measure based on an MSM-focused sexual behavior assessment that has been employed in previous trials (see reference below). Condomless sex will be compared across baseline, 3-months post-baseline, and 6-months post-baseline sessions.

    The Explore Team. Effects of a behavioural intervention to reduce acquisition of HIV infection among men who have sex with men: the EXPLORE randomised controlled study. Lancet 2004;364:41-50.

    Measured: Six months (i.e., baseline, 3-months post-baseline, 6-months post-baseline)

  6. Sexually Transmitted Infection (STI) Incidence

    Incident sexually transmitted infections (STIs) during the 6-month follow-up period will be identified through clinic chart extraction.

    Measured: Six-month follow-up period
