About this study

Official title: Adjunctive Cannabidiol for Recovery From Opioid Study (ACROS)

The long-term goal of the project is to determine whether cannabidiol (CBD) can reduce craving and relapse in individuals with opioid use disorder (OUD). The first phase of this project was an open cross-over design study in healthy individuals to confirm the safety and pharmacokinetic (PK) effects of CBD (BSPG CBD; Brains Bioceutical). The second phase was a double-blinded randomized controlled trial to determine whether CBD reduces craving and anxiety in individuals with OUD maintained on opioid agonist therapy. This phase 3 trial will determine whether CBD can serve as a potential adjunct treatment to reduce illicit opioid use in individuals with OUD maintained on opioid agonist therapy.

Read the detailed description

Responding to the urgent calls for developing non-opioid therapeutics to address the opioid addiction epidemic, we have been investigating the therapeutic potential of cannabidiol (CBD), a non-intoxicating cannabinoid as a possible strategy. Our preclinical animal studies demonstrated that CBD decreases cue-induced heroin seeking behavior during drug abstinence, associated with the incubation of craving. Moreover, the effects of CBD to reduce heroin-seeking behavior was still evident even in animals that were maintained on methadone. We also showed in randomized, double-blind placebo- controlled design human clinical trials that acute CBD (Epidiolex) administration (400 mg and 800mg) decreased craving and anxiety associated with heroin cues in abstinent individuals with heroin use disorder, an effect that persisted even a week after the last CBD dose (given daily for 3 days). Moreover, another of our human studies showed that CBD was safe even in combination with a potent opioid agonist (fentanyl) to address a potential relapse condition suggesting negligible negative interaction with opioids. Building on those studies, we next set out to investigate the potential for CBD as an adjunctive treatment to methadone or buprenorphine in opioid use disorder (OUD). To that end, we first conducted Phase 1 pharmacokinetic studies with a CBD formulation in oral capsules (BSPG CBD; Brains Bioceutical) in healthy participants that showed that oral administration of BSPG CBD (400 mg) led to comparable pharmacokinetic parameters of the CBD plasma levels and its active metabolite as Epidiolex (400 mg), an FDA-approved comparator CBD product that previously reduced craving. In the Phase 2 clinical trial, we evaluated the effect of 200mg CBD (vs placebo) twice daily for 4 weeks and an additional 4 weeks of 400 mg CBD, twice daily, on cue-induced craving and anxiety in individuals with OUD who are maintained on methadone or buprenorphine. In the next phase of this IND application, we will extend the Phase 2 study to evaluate the effects of 200mg CBD, 400 mg CBD and placebo, taken twice daily, over a 24-week period in the OUD individuals maintained on methadone or buprenorphine. Our goals in this double-blinded randomized controlled clinical trial (RCT) are to investigate the potential of CBD to 1) decrease illicit opioid use and 2) reduce craving.

Model description
Randomization will be carried out within each site using stratification factors. Using stratified block randomization with randomly varying block sizes, participants who meet the eligibility requirements and provide informed consent will be randomly allocated to one of the study arms (1 capsule CBD (200 mg), 2 capsules CBD (400 mg), 1 capsule placebo and 2 capsules placebo) with a 1:1:0.5:0.5 allocation ratio. The placebo groups will be combined for statistical analysis purposes. Random permuted blocks sizes within stratification groups will be used to minimize the chance of selection bias.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Cannabidiol in people with Opioid Use Disorder (OUD), run by Icahn School of Medicine at Mount Sinai at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 1 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Zoe Spieler (929-923-3216, Zoe.Spieler@mountsinai.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of study participants with negative urine toxicology for illicit opioid use (time frame: 24 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Oct 2026.
