PSORIASIS MEDICINE MAY HELP CONTROL ALCOHOLISM

Researchers have found in a new study that Apremilast, an FDA-approved anti-inflammatory medication used to treat psoriasis and psoriatic arthritis, may curb drinking significantly and could be an incredibly promising treatment for alcohol use disorder.

The study was recently published in the Journal of Clinical Investigation.

On average, the people who received the medication, called apremilast, reduced their alcohol intake by more than half from five drinks per day to two.

Beginning in 2015, Ozburn and collaborators searched a genetic database looking for compounds likely to counteract the expression of genes known to be linked to heavy alcohol use. Apremilast, an FDA-approved anti-inflammatory medication used to treat psoriasis and psoriatic arthritis, appeared to be a promising candidate.

They then tested it in two unique animal models that have a genetic risk for excessive drinking, as well as in other strains of mice at laboratories across the country. In each case, apremilast reduced drinking among a variety of models predisposed to mild to heavy alcohol use. They found that apremilast triggered an increase in activity in the nucleus accumbens, the region of the brain involved in controlling alcohol intake.

Researchers at the Scripps Research Institute in La Jolla, California, then tested apremilast in people. The Scripps team conducted a double-blind, placebo-controlled clinical proof-of-concept study involving 51 people who were assessed over 11 days of treatment.

“Apremilast’s large effect size on reducing drinking, combined with its good tolerability in our participants, suggests it is an excellent candidate for further evaluation as a novel treatment for people with alcohol use disorder,” said co-senior author Barbara Mason, Ph.D., Pearson Family professor in the Department of Molecular Medicine at Scripps.

The clinical study involved people with alcohol use disorder who weren’t seeking any form of treatment, and Mason predicts that apremilast may be even more effective among people who are motivated to reduce their alcohol consumption.

“It’s imperative for more clinical trials to be done on people seeking treatment,” Ozburn said. “In this study, we saw that apremilast worked in mice. It worked in different labs, and it worked in people. This is incredibly promising for the treatment of addiction in general.”
