Trial Summary

What is the purpose of this trial?

This study will examine the effectiveness of opioid use disorder (OUD) treatment linkage strategies for patients seen at sexual health clinics. This 3-arm RCT will compare Usual Care vs. Patient Navigation vs. Patient Navigation + Buprenorphine Initiation (UC vs. PN vs. PN+BUP).

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are currently on buprenorphine, methadone, or extended-release naltrexone for opioid use disorder, you cannot participate in this study.

What data supports the effectiveness of the drug Buprenorphine for treating opioid use disorder?

Research shows that Buprenorphine is effective for treating opioid use disorder, as it helps reduce opioid cravings and withdrawal symptoms. It has been approved for office-based treatment to make it more accessible to people with opioid addiction. ^{1 2 3 4 5}

Is buprenorphine safe for humans?

Buprenorphine is generally considered safe for treating opioid use disorder, with a lower risk of overdose compared to other treatments. However, misuse, especially through intravenous use, can lead to serious health issues like tissue damage and heart infections. ^{6 7 8 9 10}

How is the drug Buprenorphine unique for treating opioid use disorder?

Buprenorphine is unique because it can be combined with naloxone to reduce misuse risk while maintaining effectiveness, and it is available in extended-release formulations that improve adherence by reducing the need for daily dosing. ^{5 8 11 12 13}

Treatment Details

Interventions

• Buprenorphine
• Patient Navigation

Trial Overview The study compares three strategies at sexual health clinics: usual care; patient navigation (PN); and PN plus immediate start of buprenorphine (PN+BUP). The goal is to see which method best helps patients link to opioid use disorder treatments.

Participant Groups

Group I: Patient Navigation + Buprenorphine Initiation (PN+BUP) Experimental Treatment 2 Interventions

The PN+BUP Arm will include all PN Arm services, with the addition of meeting with the sexual health clinic's buprenorphine-waivered provider (typically a nurse practitioner) to initiate buprenorphine treatment, as a bridge until successful transfer to OUD treatment in the community. The standard buprenorphine bridge prescription will be for buprenorphine/naloxone film: 8/2mg, up to 16mg per day, 7 day supply.

Group II: Patient Navigation (PN) Active Control 1 Intervention

The PN Arm will include all UC Arm services, with the addition of a Patient Navigator who will assist the participant in selecting a community OUD treatment program, facilitate an intake appointment, help to resolve barriers and coordinate OUD treatment entry, and support early retention in OUD treatment.

Group III: Usual Care (UC) Active Control 1 Intervention

The UC Arm will include standard services from the sexual health clinic / city health department \[at the time of the study, no standardized intervention for opioid use disorder treatment linkage\].

Buprenorphine is already approved in United States, European Union for the following indications:

Approved in United States as Buprenorphine for:

• Moderate to severe opioid addiction (dependence)

Approved in European Union as Buprenorphine for:

• Opioid dependence

Findings from Research

Buprenorphine, particularly the brand-name formulations like Suboxone, has been significantly more utilized and reimbursed in Medicaid compared to other formulations, with brand-name versions dispensed 2.7 times more and costing 4.4 times more than all other formulations combined from 2002 to 2018.

Delays in the availability of generic buprenorphine formulations due to market and regulatory factors contributed to increased costs and may have hindered access to treatment for opioid use disorder during the opioid crisis.

After three years of buprenorphine's approval for office-based treatment of opioid addiction, nearly 90% of addiction specialists were authorized to prescribe it, with two-thirds actively treating patients, indicating strong adoption among specialists.

In contrast, fewer than 10% of non-addiction specialist psychiatrists prescribed buprenorphine, highlighting a significant gap in treatment access and suggesting that organizational support and training are crucial for expanding its use beyond addiction specialists.

In a study of 533 participants over 18 months after stopping extended-release buprenorphine injection (BUP-XR), 47% reported sustained opioid abstinence, with higher rates of abstinence linked to longer treatment durations.

More than 60% of participants showed stable or improved outcomes in health-related quality of life and mental health scores, indicating that BUP-XR has a long-term positive impact on recovery from opioid use disorder.

Buprenorphine (Subutex) is recognized for its improved safety profile in treating opioid dependence, particularly by reducing the risk of overdose compared to other opioids.

Despite its safety advantages, there are still risks associated with the diversion of buprenorphine for misuse, as evidenced by cases of attempted intravenous injection, highlighting the need for strict dispensing protocols.

New prolonged-release formulations of buprenorphine, including a six-month implant and two subcutaneous injection depots, aim to improve patient comfort and safety by reducing the need for daily intake and minimizing risks associated with sublingual forms.

These formulations have shown promise in addressing concerns about treatment adherence, particularly for stabilized patients, while also raising some apprehensions about potential coercive use among opioid users.

A study involving 53 opioid-dependent patients showed that switching from buprenorphine to buprenorphine/naloxone was well-tolerated, with no significant issues reported during the transition.

Patients expressed a preference for buprenorphine/naloxone over buprenorphine, with 54% favoring the combination formulation due to its taste and ease of use, indicating it may be a more acceptable option for maintenance treatment.

Buprenorphine, approved for treating opiate dependence, has been found to have an abuse potential similar to that of traditional opioids like morphine, despite initial beliefs of its low abuse risk.

A study of 120 buprenorphine abusers revealed that the majority were middle-aged males with a significant history of early illicit drug use, highlighting a concerning trend of prescription medication abuse that requires increased awareness and vigilance among healthcare professionals.

The study will involve 280 adults with opioid use disorder and aims to improve adherence to buprenorphine-naloxone treatment through two psychological interventions: contingency management (CM) and brief motivational interviewing plus substance-free activities and mindfulness (BSM).

The primary goal is to assess which intervention is more effective in promoting medication adherence, measured by attendance at physician appointments and the presence of buprenorphine in urine toxicology, with follow-up occurring 8 months after randomization.

In a study involving 546 buprenorphine prescribers across six U.S. jurisdictions, only 54% of Medicaid patients and 62% of uninsured patients were offered new appointments for buprenorphine treatment, indicating significant barriers to access for those seeking help for opioid use disorder.

Despite these barriers, the median wait times for appointments were relatively short, at around 6 days for Medicaid patients and 5 days for uninsured patients, suggesting that there is potential to improve access to treatment by better utilizing the existing prescriber workforce.

The novel weekly subcutaneous buprenorphine depot formulation, CAM2038, was found to effectively block the euphoric effects of opioids and suppress withdrawal symptoms in individuals with moderate-to-severe opioid use disorder, based on a study involving 47 participants.

Both doses of CAM2038 (24 mg and 32 mg) were well-tolerated and demonstrated significant efficacy in preventing opioid effects, making it a promising alternative to daily oral formulations that carry risks of misuse and nonadherence.
