Dronabinol Naltrexone Treatment for Opioid Dependence (Domino)

May 17, 2018 updated by: Adam Bisaga, New York State Psychiatric Institute
The goal of this two-year study is to test the efficacy of dronabinol as an adjunct to maintenance treatment with naltrexone in opioid-dependent individuals. We hypothesize that administering dronabinol during detoxification and during the first few weeks of naltrexone treatment will lead to improved naltrexone tolerability, resulting in better naltrexone compliance and treatment retention, and ultimately a reduction in opioid use and relapse rates.

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The goal of this two-year study is to test the efficacy of dronabinol as an adjunct to maintenance treatment with naltrexone in opioid-dependent individuals. We are proposing a randomized, double-blind, placebo controlled, parallel-groups, 8 week study of relapse prevention in opioid-dependent individuals. Participants will be randomized into one of two conditions (1) Naltrexone and Placebo (N=20) and (2) Naltrexone and dronabinol 15 mg bid (N=40). Treatment will be delivered in an outpatient setting except for the initial phase of inpatient detoxification, lasting 8 days. A long-acting, injectable form of naltrexone 380 mg (Vivitrol) will be administered once per month (the total of two injections), while dronabinol or placebo will be taken daily. In addition, patients will receive a psychosocial intervention that will include elements of motivational interviewing and cognitive-behavioral relapse prevention therapy. The primary aim is to test the efficacy of dronabinol in improving tolerability of naltrexone induction and reducing attrition during detoxification and the first two months of naltrexone treatment. The primary outcome will be the severity of opiate withdrawal and craving. The secondary outcome will be will be retention in treatment at study's end.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

18 years to 60 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • 1. Adult, aged 18-60.
  • 2. Meets Diagnostic and Statistical Manual -IV criteria for current opiate dependence disorder of at least six months duration, supported by a positive urine for opiates and a positive naloxone challenge test if the diagnosis is unclear.
  • 3. Have a history of marijuana use (more than 30 occasions lifetime)
  • 4. Voluntarily seeking treatment for opioid dependence
  • 5. In otherwise good health based on complete medical history, physical examination, vital signs measurement, ECG, and laboratory tests (hematology, blood chemistry, urinalysis) within normal ranges.
  • 6. Able to give informed consent.

Exclusion Criteria:

  • 1. Physiologically dependent on alcohol or sedative-hypnotics with impending withdrawal.
  • 2. Patients meeting current criteria for cannabis abuse or dependence, and those who used cannabis in the week prior to study entry as documented by the positive toxicology
  • 3. Current Diagnostic and Statistical Manual -IV criteria of other substance use disorders. Exceptions include cannabis abuse or dependence, nicotine dependence, cocaine abuse or dependence, alcohol abuse or alcohol dependence without physiological dependence as long as opioid dependence is a primary disorder. Alcohol dependence with physiological dependence is exclusionary.
  • 4. Significant current suicidal risk or 1 or more suicide attempts within the past year
  • 5. History of accidental drug overdose in the last three years defined as an episode of opioid-induced unconsciousness or incapacitation, whether or not medical treatment was sought or received.
  • 6. Positive serum pregnancy test, lactation, or unwillingness to use a satisfactory method of birth control
  • 7. Active psychiatric disorder which might interfere with participation or make participation hazardous, including Diagnostic and Statistical Manual -IV organic mental disorder, psychotic disorder, or bipolar disorder with mania
  • 8. History of allergic reaction, adverse reaction, or sensitivity to any study medication.
  • 9. Acute hepatitis with serum glutamic-oxaloacetic transaminase or serum glutamic-pyruvic transaminase > 3 times the upper end of the laboratory normal range (chronic hepatitis is acceptable as we have found naltrexone treatment well tolerate and safe among patients with chronic hepatitis)
  • 10. Currently prescribed or regularly taking opiates for chronic pain or medical illness.
  • 11. Current participation in a methadone maintenance treatment program and/or regular use of illicit methadone (>30 mg per week).
  • 12. Current participation in another intensive psychotherapy or substance abuse treatment program or participation in another treatment study.
  • 13. Concurrent treatment with psychotropic medications

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Opiate Withdrawal Measured by the Subjective Opiate Withdrawal Scale (SOWS) .
Time Frame: 3x/week during 8 weeks of the trial or study participation
The Subjective Opiate Withdrawal Scale is a self-administered 16 scale containing 16 symptoms ranging in severity from 0 (not at all) to 4 (extremely). The SOWS total score is the sum of 16 items, ranging from 0 (no opiate withdrawal ) to 64 ( severe opiate withdrawal). Values from multiple assessments during the 8-week outpatient phase were averaged.
