EXHIT ENTRE Comparative Effectiveness Trial (EXHITENTRE)

December 2, 2025 updated by: Gavin Bart

Exemplar Hospital Initiation Trial to Enhance Treatment Engagement - Comparative Effectiveness Trial of Extended Release Buprenorphine Versus Treatment as Usual for Hospitalized Patients With Opioid Use Disorder

This study is a multi-site open-label randomized comparative effectiveness trial of a 28-day formulation of extended-release buprenorphine (XR-BUP) versus treatment as usual (TAU) for hospitalized patients with a moderate or severe opioid use disorder (OUD) seen by an addiction consultation service (ACS) and agreeing to initiate a medication for OUD (MOUD). Participants will be randomly assigned to XR-BUP or TAU to be received within 72 hours of anticipated hospital discharge. Follow up will occur at approximately 34, 90, and 180 days following hospital discharge.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study will randomize approximately 314 hospitalized men and women ages 18 years and older with opioid use disorder (OUD) moderate or severe and who have not been taking prescribed medication for OUD (MOUD) for 14 days or more prior to hospitalization. Eligibility will be determined over one or more assessments during the index hospitalization. Once eligibility has been determined, participants will be randomized 1:1 to either a single injection of extended-release buprenorphine or TAU, which will include methadone, sublingual buprenorphine, or naltrexone. Connection to OUD care and ongoing MOUD following hospitalization will be per community standard. Participants will be assessed for engagement in OUD treatment by the presence of a legitimately prescribed MOUD on day 34 following hospital discharge. Further outcomes will be assessed at 90 and 180 days following hospital discharge.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Hospitalized.
  2. At least 18 years of age.
  3. Meet Diagnostic and Statistical Manual (DSM-5) criteria for moderate or severe OUD.
  4. Willing to initiate MOUD, including buprenorphine.
  5. Able to speak English sufficiently to understand the study procedures and provide written informed consent to participate in the study.

Exclusion Criteria:

  1. Anticipated length of stay less than 24-hours as determined by the ACS

  2. Affected by a serious medical, psychiatric, or substance use disorder that, in the opinion of the study physician, would make it unsafe to participate in the study or may prevent collection of study data. This may include:

    1. Disabling terminal diagnosis for which discharge from hospital is not anticipated.
    2. Disabling terminal diagnosis for which hospice care is being sought.
    3. Severe alcohol or benzodiazepine use disorder that is anticipated to require complex medical detoxification which cannot be completed prior to randomization.
  3. Taking a long-acting opioid other than buprenorphine (e.g., methadone, extended-release oxycodone, extended-release morphine) in the three consecutive days prior to randomization.
  4. Liver enzyme tests (Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT)) more than 5 times upper limit of normal or chronic decompensated liver disease.
  5. Currently pregnant.
  6. Known allergy to buprenorphine or components of Atrigel delivery system.
  7. Receipt of MOUD in the 14 days prior to hospitalization as maintenance treatment; however, patients may have received MOUD for withdrawal management during or prior to hospitalization at the time of enrollment.
  8. Are currently in jail, prison or other overnight facility as required by court of law and/or is considered a prisoner under local law or is under current terms of civil commitment or guardianship.
  9. Previously randomized as a participant in the study - individuals may only be enrolled and randomized once.
