Abstract

Treatment options for alcohol use disorders (AUDs) have minimally advanced since 2004, while the annual deaths and economic toll have increased alarmingly. Phosphodiesterase type 4 (PDE4) is associated with alcohol and nicotine dependence. PDE4 inhibitors were identified as a potential AUD treatment using a bioinformatics approach. We prioritized a newer PDE4 inhibitor, apremilast, as ideal for repurposing (i.e., FDA approved for psoriasis, low incidence of adverse events, excellent safety profile) and tested it using multiple animal strains and models, as well as in a human phase IIa study. We found that apremilast reduced binge-like alcohol intake and behavioral measures of alcohol motivation in mouse models of genetic risk for drinking to intoxication. Apremilast also reduced excessive alcohol drinking in models of stress-facilitated drinking and alcohol dependence. Using site-directed drug infusions and electrophysiology, we uncovered that apremilast may act to lessen drinking in mice by increasing neural activity in the nucleus accumbens, a key brain region in the regulation of alcohol intake. Importantly, apremilast (90 mg/d) reduced excessive drinking in non-treatment-seeking individuals with AUD in a double-blind, placebo-controlled study. These results demonstrate that apremilast suppresses excessive alcohol drinking across the spectrum of AUD severity.

  • In an RCT encompassing animal and human trials, apremilast effectively reduced excessive alcohol consumption across various models and in individuals with AUD.

    “demonstrating that apremilast effectively reduced excessive alcohol consumption across various models and in individuals with AUD”

    From A Narrative Review of Current and Emerging Trends in the Treatment of Alcohol Use Disorder (2024) · cites this paper as [88]

    The Results report reduced alcohol intake in several mouse models, and the Discussion reports reduced drinking versus placebo in 51 people with severe AUD. However, the characterization of this as an RCT encompassing animal and human trials is inaccurate: the randomized, placebo-controlled trial involved human participants, while the animal experiments were separate preclinical studies.

  • Apremilast exhibited a significant reduction in drinking, surpassing the efficacy of existing FDA-approved treatments for AUD such as acamprosate and naltrexone.

  • The nucleus accumbens (NAc) region was identified as critical for regulating alcohol-related behaviors, and apremilast was found to impact the functional activity of specific neural cell types within the NAc.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
