Official title: Withdrawal-Related Dysphoria as a Moderator of Ibudilast for Alcohol Use Disorder

Alcohol use disorder (AUD) is a prevalent and disabling psychiatric disorder with few, and only moderately efficacious, treatment options. Consequently, the identification of novel treatment targets and the development of rigorous laboratory paradigms to screen and optimize novel therapeutics represents a research priority. Ibudilast (IBUD) is a neuroimmune modulator that inhibits phosphodiesterase-4 and -10 and macrophage migration inhibitory factor. Recently in an AUD sample, IBUD was shown to decrease reactivity to a psychological stressor. Furthermore, IBUD was effective in blunting alcohol reward among participants with greater depressive symptoms, a hallmark symptom of protracted withdrawal. Recently, preclinical research in opiates has demonstrated that drug withdrawal is necessary for microglia activation and neuroinflammation in reward networks, suggesting that IBUD may be most effective among patients who experience withdrawal-related dysphoria. Therefore, this proposed study aims to examine withdrawal-related dysphoria as a moderator of IBUD efficacy in the natural environment measured using Daily Diary Assessment (DDA) approaches. To accomplish this aim, participants meeting criteria for AUD and balanced on the presence of withdrawal-related dysphoria will be enrolled in a double-blinded IBUD trial including consisting of two weeks randomized to medication and DDA assessment. The proposed research aims are:

Aim 1: Test whether IBUD reduces basal negative affect in abstinence, and blunts alcohol-related negative reinforcement. It is hypothesized that IBUD will reduce basal levels of negative affect during alcohol abstinence, and in so doing will interfere with alcohol-induced blunting of negative affectivity as captured during naturalistic drinking episodes.

Aim 2: Test whether IBUD attenuates neural alcohol cue-reactivity. It is hypothesized that IBUD will reduce BOLD activation to alcohol cues in mesocorticolimbic reward circuitry.

Aim 3: Test whether withdrawal-related dysphoria moderates the effects of IBUD. It is hypothesized that IBUD will alleviate basal negative affect, interfere with alcohol-induced negative reinforcement and attenuate BOLD activation to alcohol cues only among participants who experience dysphoria in withdrawal.

Aim 4: Test whether neural activation to alcohol cues is predictive of drinking outcomes. It is hypothesized that individuals with higher mesocorticolimbic activation to alcohol cues will report more drinking in the week following the neuroimaging session.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Negative Affect

    Negative affect as measured by self-reported ratings of "Downhearted", "Discouraged", "Uneasy", and "Anxious". Each item was rated on a scale from 0 (not at all) to 4 (extremely). The 4 items were summed for the total negative affect score for each day, ranging from 0 - 16. Higher scores indicate more negative mood.

    Measured: Assessed through daily prompts throughout the 2-week study period.

Secondary outcomes (3)
  1. Heavy Drinking

    Medication effects on number of heavy drinking days. Heavy drinking is defined by the National Institute on Alcohol Abuse and Alcoholism (NIAAA) as ≥5 drinks/day for men and ≥4 drinks/day for women. Values indicate estimated probability of a heavy drinking day across time for each group.

    Measured: 14 days

  2. Any Drinking

    Medication effects on number of days where any drinking was reported. . Values indicate estimated probability of a drinking day across time for each group.

    Measured: 14 days

  3. Ventral Striatum Activation

    Medication effect on alcohol cue-induced ventral striatal activation. Participants completed an fMRI alcohol cue-reactivity paradigm where they viewed pictures of alcoholic beverages, non-alcoholic beverages, blurred images, and a plus sign. The mean percent signal change between the ALC and BEV blocks was extracted from an a priori defined region of interest: bilateral ventral striatum (VS), 6 mm-radius sphere centered at ±12 6 9 in MNI space.

    Measured: Day 8

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ibudilast in people with Alcohol Use Disorder, run by University of California, Los Angeles 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 4 inclusion and 11 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 7 Oct 2021. 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 7 Oct 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Negative Affect (time frame: Assessed through daily prompts throughout the 2-week study period.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03489850, which also lists 2 linked publications.

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 7 Oct 2021.
