Minocycline for Alcohol Use Disorder

January 22, 2019 updated by: University of California, Los Angeles

Development of Minocycline as a Neuroimmune Therapy for Alcohol Use Disorder

The objective of this proposal is to advance medication development for alcohol use disorder by examining the efficacy and mechanisms of action of minocycline, a neuroimmune modulator, as a potential treatment. This study has important clinical implications, as the available treatments for alcohol use disorder are only modestly effective and testing novel medications is a high research priority.

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

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

Detailed Description

The research objective of this project is to advance medication development for AUD by conducting a randomized, double blind, placebo-controlled, neuroimaging study to examine the effects of minocycline on neuroinflammation, alcohol cue reactivity, neurocognitive performance, and alcohol use. In the proposed study, non-treatment seeking individuals with a current DSM-5 AUD diagnosis (N = 32) will be randomized to receive either 200 mg of minocycline per day or placebo for 28 days and complete two laboratory sessions. The first laboratory session will be performed immediately before commencing the medication regimen (day 0) and the second will be completed after taking the medication daily for 28 days. Within each laboratory session, participants will complete a cue reactivity paradigm, neurocognitive performance tasks, and a positron emission tomography (PET) imaging session. Neuroinflammation will be assessed by using PET imaging with the radiotracer N-(2,5-dimethoxy-benzyl)-N-(5-fluoro-2-phenoxyphenyl) acetamide, labeled with carbon-11 ([11C]-DAA1106), which binds to the mitochondrial translocator protein, a marker of activated microglia in brain. Additionally, blood samples will be drawn on days 0, 7, 14, 21, and 28 to measure circulating levels of proinflammatory markers and alcohol use over the four weeks of treatment will also be measured.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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.

  • Phase 1

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

21 years to 55 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Ages 25 - 45
  2. Meet DSM-5 diagnostic criteria for an AUD [n.b., only participants with moderate or severe AUD will be enrolled]
  3. Drink ≥ 48 standard drinks in a 30-day period before enrollment

Exclusion Criteria:

  1. Currently in treatment for AUD, a history of treatment in the 30 days before enrollment, or currently treatment seeking
  2. Current (last 12 months) DSM-V diagnosis of substance use disorder for any psychoactive substances other than alcohol and nicotine
  3. Lifetime DSM-V diagnosis of schizophrenia, bipolar disorder, or any psychotic disorder
  4. Positive urine screen for narcotics, amphetamines, or sedative hypnotics
  5. Serious alcohol withdrawal symptoms as indicated by a score ≥ 10 on the Clinical Institute Withdrawal Assessment for Alcohol-Revised
  6. Pregnancy, nursing, or refusal to use reliable method of birth control (if female)
  7. A medical condition that may interfere with safe study participation (e.g., unstable cardiac, renal, or liver disease, uncontrolled hypertension or diabetes)
  8. AST, ALT, or GGT ≥ 3 times upper normal limit
  9. Attempted suicide in the past 3 years and/or serious suicidal intention or plan within the past year
  10. Currently on prescription medication that contraindicates use of MINO
  11. Any other circumstances that, in the opinion of the investigators, compromises participant safety.
  12. Claustrophobia
  13. Participating in any other research study involving exposure to ionizing radiation in the past year will be excluded if the total cumulative exposure from the past research studies and the current research study would exceed the limits set by the FDA in 21 CFR 361.1. Specifically, the total cumulated dose to the whole body, active blood-forming organs, lens of the eye, and gonads must remain below 5 rems, and the cumulated dose to all other organs must remain below 15 rems. Potential participants who have had exposure to ionizing radiation in the past year will not be allowed to participate if we are unable to obtain proper documentation quantifying the amount of past exposure.
  14. Presence of a metal device in the body (e.g., pacemaker, infusion pump, aneurysm clip, metal prosthesis or plate): Those devices could either interfere with the acquisition of the MRI scan of the brain or for whom the MRI scan would pose a potential risk. If participants have a non-removable device in their body, they must acquire and show a document exhibiting the device is MRI-compatible.
