What is the purpose of this trial?

This trial tests a new treatment, INDV-6001, a 3-month long-acting injectable buprenorphine, for individuals with opioid use disorder (OUD). The main goal is to understand how the body processes the drug and to determine the optimal dosing plan. Participants will first stabilize on the current medication, SUBOXONE, before transitioning to INDV-6001. The trial will also explore different injection sites, such as the thigh and the back of the upper arm. Individuals with moderate or severe OUD who are already using certain opioid treatments may be suitable candidates for this study. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.

Will I have to stop taking my current medications?

Participants must not take any buprenorphine-containing products other than those provided in the study. Additionally, they should not be using medications that affect certain liver enzymes (CYP3A4 or CYP2C8) within 30 days before joining the study.

Is there any evidence suggesting that INDV-6001 is likely to be safe for humans?

Studies have shown that treatments like INDV-6001, such as monthly buprenorphine injections, are generally well-tolerated by people with opioid use disorder. These treatments help maintain sobriety by reducing cravings and withdrawal symptoms. In previous research, participants experienced some side effects, usually mild, like soreness at the injection site or mild nausea. Serious side effects were rare.

Since INDV-6001 is in Phase 2 trials, early safety data suggest it has been safe enough in earlier studies to continue testing. This phase gathers more detailed safety information. Researchers are testing INDV-6001 in different doses and closely monitoring for any negative effects. The goal is to find a balance between effectiveness and minimal side effects.

Participants switching from other buprenorphine treatments, like SUBOXONE or SUBLOCADE, might find the side effects similar to previous experiences. Overall, while some risk exists, current data supports a reasonable safety profile for INDV-6001 in treating opioid use disorder. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for opioid use disorder?

Researchers are excited about INDV-6001 for opioid use disorder because it offers a novel approach by combining Suboxone with periodic doses of INDV-6001. Unlike standard treatments, which often require daily dosing, INDV-6001 is administered in larger doses at less frequent intervals, potentially improving patient adherence and convenience. This treatment also explores different dosing schedules and combinations with Sublocade, offering flexibility and personalization in managing opioid use disorder. These unique features could lead to more effective and patient-friendly treatment options, addressing both withdrawal symptoms and long-term recovery support.

What evidence suggests that INDV-6001 might be an effective treatment for opioid use disorder?

Research has shown that high levels of buprenorphine, the main ingredient in INDV-6001, can assist individuals with opioid use disorder (OUD), particularly those using drugs like fentanyl. One study found that long-lasting buprenorphine injections support long-term recovery from OUD. The evidence confirms that these treatments are both effective and safe. INDV-6001, which participants in this trial may receive, is a new version that functions like existing buprenorphine treatments by providing steady medication levels to help manage OUD. Early results suggest this method could be promising for those dealing with opioid addiction. ^{1 6 7 8 9}

What Are the Treatments Tested in This Trial?

Interventions

• INDV-6001

In 2017, only 38% of substance use treatment facilities in the U.S. offered any medication for opioid use disorder (MOUD), with 62% providing extended-release naltrexone (XR-NTX) but only 3% offering the buprenorphine implant.

The availability of XR-NTX was higher in certain regions and federally-funded facilities, particularly in states with high opioid overdose mortality rates, highlighting a need to improve access to long-acting MOUD options to better address opioid use disorder.

Predictors of availability of long-acting medication for opioid use disorder. Shover, CL., Humphreys, K.[2020]

In a study involving 570 adults with opioid use disorder, buprenorphine-naloxone was found to be more cost-effective than extended-release naltrexone, being preferred in 97% of cases at 24 weeks and 85% at 36 weeks based on quality-adjusted life-years (QALYs).

The analysis suggests that buprenorphine-naloxone is the better first-line treatment option, especially for patients needing detoxification before starting extended-release naltrexone, although the study had limitations such as a relatively short follow-up period.

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.

Methadone and buprenorphine are effective first-line treatments for opioid dependence, with new long-acting formulations like CAM 2038 (Buvidal®), RBP-6000 (Sublocade™), and Probuphine™ offering innovative options for maintenance therapy.

These long-acting buprenorphine formulations provide flexibility in treatment schedules, potentially improving adherence and outcomes for individuals with opioid dependence.

Long-acting buprenorphine formulations, including CAM 2038 (Buvidal), RBP-6000 (Sublocade™), and Probuphine™, provide effective options for treating opioid use disorders (OUDs) with varying administration schedules, such as weekly, monthly, or every six months.

These depot and implant formulations enhance patient adherence to treatment by reducing the frequency of dosing compared to traditional oral or sublingual medications, potentially improving overall outcomes in managing OUDs.
