Clinical Trial Summary

The goal of this randomized controlled trial is to test the effectiveness of "TIARAS," a trauma intervention designed to reduce HIV acquisition risk among women who inject drugs (WWID). To be eligible for this study, participants must have been prescribed pre-exposure prophylaxis (PrEP), a medication taken to prevent HIV for Prevention Point Philadelphia, a large harm reduction agency located in Philadelphia (PA, USA). Enrollment in this study lasts for 12-months so that we can see if TIARAS reduces HIV risk immediately after the intervention ends and whether these effects last over time. During the first 3 months, participants engage in contingency management (CM), an evidenced-based intervention to reduce drug use and HIV risk. We will use CM to encourage engagement in PrEP care as well as stimulant/opioid abstinence. Also during the first 3-months, participants are randomly assigned to complete expressive writing exercises to address a previously undisclosed trauma or neutral writing exercises. Half of the participants will be assigned to the trauma writing group and the other half will be assigned to the neutral writing group. To understand the impact of TIARAS on HIV risk, we will collect and analyze data from surveys, interviews, and biological specimen during the 12-month study period. Our main questions are: - Does participation in TIARAS reduce HIV risk among WWID? - If observed, how long do beneficial effects last? - How and why do WWID experience benefits from TIARAS?

Description:

In the United States, recent outbreaks coast-to-coast forewarn of a possible resurgence of HIV, especially among women who inject drugs (WWID), particularly if access, uptake, and adherence to effective harm reduction tools remain sub-optimal. Pre-exposure prophylaxis (PrEP) is a user-driven method that safely and effectively prevents HIV. While we have shown that cisgender WWID consider PrEP beneficial and are willing to accept a prescription, consistent with the well-known SAVA syndemic framework, social stigma, economic insecurity, traumatic experiences (or the threat of violence), and drug use greatly undermined their agency to prioritize and adhere to PrEP. This trauma-informed randomized control trial (RCT) will address the urgent need for HIV prevention interventions, informed by the SAVA framework, that produce durable reductions in HIV risk among WWID. We will integrate contingency management (CM), a proven strategy to reduce drug use and HIV risk, and expressive writing (EW), a safe and effective approach for addressing trauma symptoms, in order to test whether EW delivered during CM (EW+CM) produces durable reductions in HIV acquisition risk compared to an attention-control condition. We will leverage our longstanding partnership with Prevention Point Philadelphia (PPP), the largest syringe exchange in the mid-Atlantic, to recruit 360 WWID who will (re)initiate PrEP at PPP. Once enrolled they will immediately begin a 3-month CM period that provides incentives for directly observed daily oral PrEP doses or confirmed injectable PrEP doses, stimulant/opioid abstinence (measured thrice weekly through urine screening), and completion of four writing sessions. After a run-in period, WWID will be randomized to either EW+CM (n=180) or Neutral Writing+CM (n=180). Follow-up assessments will occur at 3-, 6-, and 12-months post-randomization and will include objective measures of PrEP adherence over time. A subset of WWID from both arms will complete qualitative interviews at 3- and 12-months. All study activities and daily PrEP dispensing will occur at PPP. The specific aims are to: (1) Determine the efficacy of EW+CM for improving the proportion of participants achieving reductions in HIV acquisition risk (operationalized as the proportion of WWID reporting syringe sharing or condomless sex during objectively measured periods of PrEP non-adherence) at 12 months. (2) Examine key secondary outcomes such as greater PrEP persistence, reductions in substance use, PTSD symptoms, and depression, as well as entry into drug treatment over 12 months. (3) Evaluate the pathways through which the intervention operates using qualitative interviews, mediation analysis (e.g., emotional expression and processing in EW essays), and moderation analysis (e.g., more pronounced among those with higher PTSD severity at baseline). This RCT could have an exceptional impact by yielding one of the first evidence-based interventions to address HIV acquisition risk in the era of PrEP among WWID.

Intervention

Behavioral:
• Expressive Writing
Expressive writing (EW) is a safe, acceptable, and effective intervention for improving psychological adjustment. Via brief directed writing sessions, EW facilitates disclosure of traumatic events. At a basic level, emotional expression and disclosure are important because they reduce the need to unconsciously direct psychological energy towards suppressing emotions from traumatic events.
• Contingency Management
Contingency management (CM) is a proven strategy to reduce drug use and HIV risk behavior. Also known as a conditional cash transfer, CM reinforces positive behavior with tangible rewards. In the context of substance use treatment, monetary incentives are typically used to reinforce drug-negative urine specimens.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	HIV Acquisition Risk	Our primary outcome will be a composite of two measures: self-reported behavioral HIV risk (syringe sharing or condomless sex) and objectively measured adherence to PrEP. To assess PrEP adherence in women initiating daily oral Tenofovir-based (TFV) PrEP products, we will collect scalp hair at baseline, 3, 6, and 12 months. Specimens will be tested using liquid chromatography/tandem mass spectrometry to quantify TFV concentrations levels. In primary analysis, and TFV level >/= 0.025.ng, consistent with >/= 6 doses per week, will be considered adherent. To assess PrEP adherence in women initiating cabotegravir PrEP products, we will extract the dates of LAI-CAB injections from participants' electronic medical records and will determine whether each follow-up LAI-CAB injection occurred within recommended dosing windows according to Apretude prescribing information (+/- 7 days). In primary analysis, any injection occurring within the recommended dosing window will be considered adherent.	Participant duration (1 year)
Secondary	Reductions in Drug Use	At each study visit, participants will complete The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), which assesses lifetime and recent (past 90 day) drug use. We will describe recent substance use and determine whether there are clinically meaningful decreases in illicit stimulant and/or opioid use over time.	Participation duration (1 year)
Secondary	Drug Abstinence	Participants will provide urine samples for oon-site toxicology screening of methamphetamine, cocaine, and opioid metabolites. Reactive urine toxicology results are indicative of stimulant/opioid use within the past 72 hours. Results of urine drug screens will be extracted from electronic medical records.	Participation duration (1 year)
Secondary	Referrals for Drug Treatment	Participant requests for a referral for drug treatment will be captured during study visits and logged into the study database. To calculate the number of referrals, we will extract data from the study database.	Participation duration (1 year)
Secondary	Depression	We will use the Beck Depression Inventory (BDI). This validated 21 item scale has a score range of 0 to 63. A cutoff score of 19 will be used to classify moderate/severe depressive symptoms.	Participation duration (1 year)
Secondary	PTSD Symptoms	We will use the PTSD checklist from DSM 5 (PCL-5). This is a 20 item validated scale with a score range 0 to 80. This generates 5 sub-scales symptom scores, which will be assessed for particular patterns of symptomology. A total cutoff score = 33 will be used to classify moderate/severe PTSD.	Participation duration (1 year)
Secondary	Cost effectiveness	Cost effectiveness will be estimated using a micro-costing approach. Cost offsets will be collected using the Non-Study Medical and Other Services (NMOS) assessment tool along with the Patient Reported Outcomes Measurement Information System (PROMIS PROPr) assessment tool to determine QUALYs. Cost data collection and analysis will be informed by the Drug Abuse Treatment Cost Analysis Program (DATCAP), a standardized costing tool used in hundreds of clinical trials over the past 3 decades.
