Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 60 years
- All sexes
- No healthy volunteers
- Adult
Who may be able to join
- Males and non-pregnant females, age 18 - 60 years old
- Subject meets DSM-5 criteria for OUD and/or other SUDs including alcohol (assessed via the SCID-5) of at least two years duration
- Subject is currently receiving outpatient treatment from the WVU Comprehensive Opioid Addiction Treatment Program (COAT), Intensive Outpatient Program (IOP) or any other program which implements the COAT model; residential or inpatient treatment from the WVU Center for Hope and Healing or an affiliated WVU hospital; or receiving outpatient/inpatient/residential treatment from similar programs that are well known to the research team. If the subject is prescribed medication for AUD or OUD (e.g. buprenorphine-naloxone, naltrexone), they will be on a stable dose of the medication for the 7 days prior to the procedure. Stable is defined as within the therapeutic range but does not require same exact dose for 7 days.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Exablate Model 4000 Type 2.0/2.1Device
There are two treatment stages. In both stages, the subject will receive both the sham and active ExAblate treatment, and be evaluated for 90 days post-treatment for adverse events. During Stage 1 the subject will receive the moderate intensity Exablate LIFU procedure. During Stage2, the subject will receive the enhanced intensity ExAblate LIFU procedure. The subjects are blinded as to the order of the sham vs active treatment.
| Study group | Role | What they receive |
|---|---|---|
| Sham/Active ExAblate Treatment Stage 1 and 2 | Other | Subject will undergo both Treatment 1 (sham) and Treatment 2 (with enhanced intensity). Subjects are blinded to the order of the sham vs active treatment. Receives: Device: Exablate Model 4000 Type 2.0/2.1 |
What is being measured
The primary outcome is the main question the study is designed to answer.
Occurrence of Treatment Emergent Adverse Events
Safety will be assessed by recording all adverse events that are treatment related. Each Adverse Event will be documented for patterns of occurence.
Measured: Post-ExAblate Procedure (Day 0) through 4 Month Follow-Up

Questions about this trial
What is this clinical trial studying?
A study testing Exablate Model 4000 Type 2.0/2.1 in people with Opioid Use Disorder, run by West Virginia University at 1 site 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 9 inclusion and 30 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: finished, as of the sponsor's last update on 20 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Occurrence of Treatment Emergent Adverse Events (time frame: Post-ExAblate Procedure (Day 0) through 4 Month Follow-Up). 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 20 Jul 2025.
