MediciNova Announces Results from Clinical Trial of MN-166 (ibudilast) in Alcohol Dependence Presented at the 39th Annual Scientific Meeting of the Research Society on Alcoholism in New Orleans, Louisiana

LA JOLLA, Calif., June 29, 2016 (GLOBE NEWSWIRE) -- MediciNova, Inc., a biopharmaceutical company traded on the NASDAQ Global Market (NASDAQ:MNOV) and the JASDAQ Market of the Tokyo Stock Exchange (Code Number:4875), today announced that researchers at the University of California, Los Angeles (Dr. Lara Ray, Principal Investigator), presented novel findings from further analysis of the completed clinical trial of MN-166 (ibudilast) in alcohol use disorder (AUD) at the 39th Annual Scientific Meeting of the Research Society on Alcoholism on June 27, 2016 at the Hyatt Regency New Orleans in New Orleans, LA.

Major highlights from the presentation, “Depressive Symptomatology Moderates the Effects of the Neuroimmune Modulator Ibudilast on Subjective Responses to Alcohol,” include the following:

In an intravenous alcohol challenge session in subjects reporting higher levels of depressive symptomatology as measured by the Beck Depressive Inventory (BDI) Scale:

  • ibudilast significantly weakened the alcohol-induced stimulatory effects (p < 0.05),
  • ibudilast significantly decreased alcohol-induced positive mood (p < 0.05),
  • ibudilast significantly decreased ‘wanting’ of alcohol (p < 0.05), and
  • ibudilast showed a trend to decreased ‘liking’ of alcohol (p = 0.061).

While ibudilast weakened the alcohol-induced rewarding effects described above during the alcohol challenge, it also enhanced a negative reaction (i.e., feeling of tension/anxiety) (p < 0.05) in subjects reporting higher levels of depressive symptomatology on the BDI.

About the Clinical Trial

This randomized, double-blind, placebo-controlled study enrolled 24 non-treatment seeking individuals with either alcohol abuse or dependence in a UCLA research unit. Participants were randomly assigned to a 7-day treatment period involving repeat oral administration of either MN-166 (ibudilast) escalated up to 100 mg/day or placebo. During the treatment period, participants were administered the study medication, completed an IV alcohol challenge, and took part in laboratory tests of alcohol craving as well as mood assessments and standard safety tests. Following a 7-10 day study break, trial participants re-enrolled for another 7-day period wherein they crossed over to the other treatment condition. The key study outcomes included safety, tolerability and preliminary efficacy as indicated by whether MN-166 (ibudilast) reduced alcohol craving and the rewarding effects of alcohol under controlled experimental conditions of cue exposure and alcohol administration.

About MN-166 (ibudilast)

MN-166 (ibudilast) has been marketed in Japan and Korea since 1989 to treat post-stroke complications and bronchial asthma. MediciNova licensed MN-166 (ibudilast) from Kyorin Pharmaceutical Co., Ltd. for potential utility in relapsing-remitting multiple sclerosis (RRMS). Intellectual property was additionally established or obtained by MediciNova in progressive MS and other neurological conditions. MN-166 (ibudilast) is a first-in-class, orally bioavailable, small molecule phosphodiesterase (PDE) 4 and 10 inhibitor and a macrophage migration inhibitory factor (MIF) inhibitor that suppresses pro-inflammatory cytokines and promotes neurotrophic factors. It attenuates activated glia cells, which play a major role in certain neurological conditions. Ibudilast's anti-neuroinflammatory and neuroprotective actions have been demonstrated in preclinical and clinical study results and provide the rationale for its therapeutic utility in neurodegenerative diseases (e.g., progressive MS and amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease), substance abuse/addiction and chronic neuropathic pain.
