Contingency Management for HIV Prevention
(CoMPASS Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to test a new approach to prevent HIV in people with opioid use disorder who have injected drugs. Researchers will evaluate whether contingency management (a reward-based system) combined with support services can improve adherence to PrEP (Pre-Exposure Prophylaxis), a medication that helps prevent HIV. Participants will receive either standard care or this new approach. Suitable candidates have a history of injecting drugs and engage in high-risk behaviors, such as sharing needles or having unprotected sex. As an unphased trial, this study offers participants the chance to contribute to innovative research that could enhance HIV prevention strategies.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the study team or your doctor.
What prior data suggests that the CoMPASS intervention is safe for individuals with opioid use disorder?
Research shows that Contingency Management (CM) is generally easy for people to handle. CM is a treatment that uses rewards to encourage good habits, such as taking medicine on time. Studies have shown that this method helps people adhere to their medication plans.
When combined with Pre-Exposure Prophylaxis (PrEP) adherence and support services, this approach aims to lower the risk of HIV, especially for people who use drugs. Previous research found that participants followed their PrEP medication plans well, suggesting they handled the treatment without many issues.
Overall, evidence suggests that using Contingency Management along with PrEP support services is safe for participants, with few reports of negative reactions.12345Why are researchers excited about this trial?
Researchers are excited about the Contingency Management with stepped care to PrEP adherence and support services (CoMPASS) because it offers a novel approach to enhancing adherence to HIV prevention strategies. Unlike standard methods that primarily rely on providing informational handouts or standard medical care, CoMPASS incorporates contingency management, which uses positive reinforcement to encourage PrEP adherence. This method steps up support for individuals struggling with adherence, potentially increasing their engagement and success in preventing HIV. By focusing on behavior change and tailored support, CoMPASS could significantly improve outcomes over traditional approaches.
What evidence suggests that CoMPASS is effective for HIV prevention?
Research has shown that using rewards to encourage good habits can help people take their medication regularly. In this trial, participants in the Contingency Management with stepped care to PrEP Adherence and Support Services (CoMPASS) arm will receive such incentives to help them adhere to their HIV prevention medication, called pre-exposure prophylaxis (PrEP). This approach, known as contingency management, has proven effective, particularly for those with opioid use disorder. By offering incentives, individuals are more likely to follow their treatment plans. Studies suggest that this method leads to better health by reducing risky behaviors that increase the chance of contracting HIV.13678

Are You a Good Fit for This Trial?
This trial is for individuals with opioid use disorder who inject drugs and are at risk for HIV. They must meet PrEP eligibility, have a recent negative HIV test, own or share a cell phone, and be willing to complete surveys. Exclusions include non-English speakers without translation support, kidney disease, current PrEP users, pregnant or breastfeeding women, and those unable to finish the study.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Contingency Management with stepped care to PrEP adherence and support services (CoMPASS)
Trial Overview
The study tests CoMPASS—a program combining contingency management with support services—to improve adherence to PrEP among people who inject drugs. It's a 24-week intervention followed by a year of monitoring their health outcomes and evaluating how well the program works in real-world settings.

Active Control
Participants randomized to Compass will also receive a health handout on HIV risk reduction approaches. They will also receive contingency management sessions (n=9). Participants who do not demonstrate PrEP adherence by week 12, will be "stepped up" to receive PrEP adherence and support services (n=5).
Participants randomized to TAU will receive a health handout on HIV risk reduction approaches, including PrEP and OUD-related care, and where to access such services. They will receive standard care as provided by the community-based organization and by their medical provider.
Contingency Management with stepped care to PrEP adherence and support services (CoMPASS) is already approved in United States, European Union for the following indications:
- Prevention of HIV-1 infection in adults and adolescents weighing at least 35 kg (77 lb) at increased risk of HIV acquisition
- Pre-exposure prophylaxis (PrEP) to reduce the risk of sexually acquired HIV-1 infection in adults at high risk
- Pre-exposure prophylaxis (PrEP) to reduce the risk of HIV-1 infection from sexual acquisition, excluding individuals at risk from receptive vaginal sex
- Pre-exposure prophylaxis (PrEP) to reduce the risk of sexually acquired HIV-1 infection in adults at high risk
