What You Need to Know Before You Apply

What is the purpose of this trial?

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, at Prevention Point Philadelphia, a large harm reduction agency located in Philadelphia (PA, USA), or Courage Medicine, a nonprofit health services clinic 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?

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, you must be on PrEP (a medication to prevent HIV) to participate.

Is contingency management safe for humans?

Contingency management, which involves providing rewards for drug abstinence, has been studied in various settings and is generally considered safe for humans. Research indicates that it does not lead to new drug use or coercion, and it is viewed positively by treatment providers.12345

How is the Contingency Management treatment unique for HIV prevention in women who inject drugs?

Contingency Management is unique because it uses motivational incentives, like prizes, to encourage positive behavior changes, such as reducing drug use and increasing safe practices, which is different from traditional treatments that may not use rewards as a primary method to promote behavior change.678910

What data supports the effectiveness of this treatment for HIV prevention in women who inject drugs?

Research shows that contingency management, which uses rewards to encourage drug abstinence, can reduce HIV risk behaviors in drug users. Additionally, motivational incentives have been effective in improving treatment engagement and outcomes in substance abuse patients, suggesting potential benefits for HIV prevention in women who inject drugs.12111213

Are You a Good Fit for This Trial?

This trial is for HIV-negative cisgender women over 18 who inject drugs and speak/read English. They must be new or non-adherent patients of PrEP at Prevention Point Philadelphia, not pregnant, able to consent, and willing to visit the site daily for 90 days and provide specimens.

Inclusion Criteria

Reporting past 6 months day non-prescription injection drug use and any of the following: NEW PrEP PATIENT: prescribed daily oral or injectable PrEP at Prevention Point Philadelphia within 30 days. For injectable PrEP, they will be considered new if they have received a prescription but have not had their first injection. or NON-ADHERENT DAILY ORAL PrEP PATIENT: initiated PrEP at Prevention Point Philadelphia 30 or more days ago who reports any non-adherence or reports consistent adherence but has PrEP-related drug levels indicating non-adherence (verified with urine-based tenofovir testing) or NON-ADHERENT INJECTABLE PrEP PATIENT: initiated injectable PrEP at Prevention Point Philadelphia but is outside of the window to receive their next injection (verified in participant's electronic medical record)
Speaks/reads English
I am a cisgender female and do not have HIV.

Exclusion Criteria

I am unable to understand and give consent for treatment.
I cannot visit the study site daily for the next 3 months.
Unwilling to provide specimen for PrEP-related clinical monitoring and adherence monitoring

What Are the Treatments Tested in This Trial?

Interventions

  • Contingency Management
  • Expressive Writing
Trial Overview The 'TIARAS' program combines contingency management with expressive writing exercises aimed at addressing trauma. The study tests if this intervention reduces HIV risk among women who inject drugs by comparing it with neutral writing exercises over a year.

Published Research Related to This Trial

Contingency management (CM) significantly reduced HIV risk behaviors among 116 methadone-maintained outpatients by providing rewards for drug abstinence, leading to lower HIV-Risk Taking Behaviour Scale (HRBS) scores over time compared to a control group.
Participants in the CM group showed a notable decrease in simultaneous cocaine and opiate use, indicating that CM effectively promotes abstinence, which in turn mediates the reduction in risky behaviors associated with HIV transmission.
Contingency management reduces injection-related HIV risk behaviors in heroin and cocaine using outpatients.Ghitza, UE., Epstein, DH., Preston, KL.[2021]
A treatment reinforcement plan (TRP) incentivized cocaine-using methadone patients with up to $15 per week for completing tasks related to their treatment, leading to significant engagement and retention in therapy.
Successful participation in the TRP during the first two months was linked to longer retention in methadone treatment, increased therapy attendance, and a reduction in cocaine use, highlighting the effectiveness of behavioral counseling techniques for high-risk patients.
Improving treatment engagement and outcomes for cocaine-using methadone patients.Villano, CL., Rosenblum, A., Magura, S., et al.[2019]
A survey of 214 substance use treatment providers revealed that while many clinics are using reward programs, they often do not follow effective practices recommended by research, such as providing higher reward amounts or immediate reinforcement.
Providers with more extensive training in contingency management (CM) were more likely to implement effective strategies, suggesting that better training could improve the quality of reward-based interventions in real-world settings.
