What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a new method to initiate treatment with buprenorphine for individuals with opioid use disorder who are using fentanyl. The researchers aim to determine if buprenorphine can be safely started without triggering withdrawal symptoms. Participants will be randomly assigned to either a standard approach or a new method that allows continued fentanyl use before starting treatment. Suitable candidates have moderate to severe opioid use disorder and test positive for fentanyl in their urine. As a Phase 2 trial, this research focuses on assessing the treatment's effectiveness in an initial, smaller group.

Will I have to stop taking my current medications?

The trial requires that you stop using certain medications, such as benzodiazepines and drugs metabolized by CYP3A4 (like some antifungals and antibiotics). If you're using these, you may need to stop them before participating.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that buprenorphine is generally safe for treating opioid addiction and has been used for this purpose since the FDA approved it in 2002. Studies have found that most patients tolerate it well.

Common side effects include nausea, headache, and sweating, but these are usually mild. Serious side effects, such as breathing problems or allergic reactions, are rare. The safety of buprenorphine is well-documented, making it a standard treatment for opioid addiction.

In this trial, both the usual and new methods involve buprenorphine. The new method uses lower doses, which might reduce the risk of side effects. However, as this is a mid-phase trial, research is ongoing to fully understand all safety aspects. Researchers closely monitor participants to ensure their safety throughout the study. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the use of buprenorphine for opioid use disorder because of its unique approach to treatment initiation. Unlike traditional methods that require patients to be in withdrawal before starting treatment, the "Rapid outpatient low-dose initiation" allows patients to begin without being in withdrawal, potentially making the process more comfortable and accessible. This method gradually increases the buprenorphine dose in a controlled environment, which could improve patient adherence and outcomes. Additionally, the "Standard initiation" follows updated guidelines to optimize effectiveness and safety, offering a structured approach that may enhance the transition from withdrawal to maintenance therapy.

What evidence suggests that this trial's treatments could be effective for opioid use disorder?

Research has shown that buprenorphine effectively treats opioid use disorder (OUD) by easing withdrawal symptoms and reducing cravings. In this trial, participants will enter different treatment arms. One arm will explore starting buprenorphine at a low dose, which studies have found effective, even for those using fentanyl. This approach is associated with higher retention rates in treatment. Overall, buprenorphine offers a promising option for managing OUD, especially when starting at a low dose quickly in an outpatient setting. ^{6 7 8 9 10}

Interventions

• Buprenorphine

Trial Overview

The study tests if buprenorphine can be started in patients using fentanyl without causing withdrawal. One group follows standard care, waiting until experiencing withdrawal symptoms before starting treatment. The other uses a rapid low-dose method without waiting.

How Is the Trial Designed?

Group I: Rapid outpatient low-dose initiation Experimental Treatment 1 Intervention

Participants randomized to low-dose initiation will be instructed to arrive to the research unit without withdrawal. Participants with COWS \<4 will be admitted to the research unit to begin induction. They will be administered 0.5, 0.5, 1, 1, 1, 4, and then 8 mg as sublingual buprenorphine films with doses scheduled every 2 hours. They will then continue 8mg twice daily (or up to three times daily) as maintenance treatment.

Group II: Standard initiation Active Control 1 Intervention

Participants randomized to standard induction will be instructed to arrive to the research unit with mild withdrawal and to have abstained from opioids for at least 8 hours, per ASAM Guidelines. Participants with COWS 4 or higher on initial assessment will be admitted to the research unit to begin induction. Standard initiation will follow guidelines from the 2020 Focused Update of the ASAM National Practice Guidelines. Once participants have had at least 8 hours of abstinence and have reached COWS 11 or greater, they will be given 2 mg sublingual buprenorphine, followed 2 hours later by 2 mg, followed 2 hours later by 4 mg, followed 2 hours later by 8 mg. They will then continue 8 mg twice (or up to three times) daily as maintenance treatment.

A study analyzing 5,970 emergency department visits in Italy found that benzodiazepines (BZD) and Z-drugs (ZD) are associated with a higher rate of adverse events (AEs) leading to hospitalization compared to opioids, particularly among younger patients and those with a history of substance abuse.

23% of BZD/ZD-related AEs were linked to drug abuse, and these cases often required hospitalization (52%), highlighting the significant health risks associated with the inappropriate use of these medications.

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.

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.

A study of 200 rural residents revealed that motivations for using nonprescribed buprenorphine shifted from initially seeking to avoid withdrawal and get high to maintaining abstinence from other drugs, indicating a complex relationship with self-treatment.

Participants with a history of treatment for opioid use disorder were more likely to use nonprescribed buprenorphine for self-treatment, suggesting that dissatisfaction with existing treatment options may drive individuals to seek alternatives outside of prescribed care.

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.

Zoledronic acid (ZOL), administered as a single intravenous infusion once a year, effectively reduces the risk of vertebral and hip fractures in postmenopausal women with osteoporosis, and also lowers the incidence of future fractures in men and women with recent hip fractures.

ZOL is generally safe and well tolerated, with mild and transient flu-like symptoms occurring after the first infusion, making it a convenient option for patients who may struggle with compliance to oral bisphosphonates.
