LA JOLLA, Calif., Aug. 20, 2018 (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 the National Institute on Alcohol Abuse and Alcoholism (NIAAA), which is part of the National Institutes of Health (NIH), will fund a Phase 2b clinical trial to evaluate MN-166 (ibudilast) as a potential treatment to decrease alcohol consumption in treatment-seeking patients with alcohol use disorder (AUD).  This study is a randomized, double-blind, placebo-controlled outpatient trial which will enroll up to 132 patients. The NIAAA R01 research funding was awarded to Principal Investigator Dr. Lara Ray, PhD, ABPP, at the University of California, Los Angeles' (UCLA) Departments of Psychology, and Psychiatry and Biobehavioral Sciences Brain Research Institute, based on her recent findings that MN-166 (ibudilast) was associated with mood improvements during stress- and alcohol-cue exposures, significantly decreased alcohol-induced stimulation and positive mood, decreased overall craving for alcohol in non-treatment seeking volunteers, and was safe and well-tolerated. 

MediciNova will provide drug supply and regulatory support for the clinical trial.

MediciNova recently announced in May 2018 that it plans to initiate a separate clinical trial evaluating MN-166 in alcohol dependence and withdrawal in approximately 50 non-treatment seeking individuals with moderate-to-severe AUD with Dr. Ray and her research group.  This study is funded by the NIH's National Institute on Drug Abuse (NIDA).  

Lara Ray, PhD, Principal Investigator of the trial, commented "We are encouraged by the clinical data from our first study of ibudilast in AUD as it is a safe and promising compound for the treatment of AUD.  If MN-166 (ibudilast) is able to reduce drinking compared to placebo in this new study, it will set the stage for a pivotal multi-site clinical trial leading to potential FDA approval of a novel AUD treatment."  

Dr. Yuichi Iwaki, President and CEO of MediciNova, commented, "We are excited to continue our collaboration with UCLA and are very pleased that NIAAA continues to support our MN-166 development efforts for AUD."

About the R01 Research Grant

The Research Project Grant (R01) is the original and historically oldest grant mechanism used by NIH. The R01 provides support for health-related research and development based on the mission of the NIH.  The Research Project (R01) grant is an award made to support a discrete, specified, circumscribed project to be performed by the named investigator(s) in an area representing the investigator's specific interest and competencies, based on the mission of the NIH.

About the Alcohol Use Disorder Trial

This study is a randomized, double-blind, placebo-controlled, outpatient clinical trial which will enroll up to 132 treatment-seeking men and women with moderate or severe AUD.  Subjects will take MN-166 (ibudilast) 50 mg or placebo twice a day for 12 weeks. Subjects will complete the NIAAA-developed web-based program Take Control during the study. The primary endpoint of the trial is to test whether MN-166 (ibudilast) will decrease percent heavy drinking days (defined as ≥ 5 drinks for men and ≥ 4 drinks for women), as compared to placebo, over the course of the 12-week trial. The secondary endpoints are to test the efficacy of MN-166 (ibudilast) on 1) the number of drinks consumed per day, 2) the number of drinks consumed per drinking day, 3) the percentage of days abstinent, 4) the percentage of subjects with no heavy drinking days, and 5) the percentage of subjects who are abstinent, as well as measures of alcohol craving and negative mood, over the course of the 12-week trial. Exploratory endpoints include evaluation of whether the effects of MN-166 (ibudilast) on the primary and secondary endpoints are moderated by depressive symptomatology and whether MN-166 (ibudilast) reduces neuroinflammation over the course of the 12-week trial.

About Alcohol Use Disorder

Alcohol use disorder (AUD) is a prevalent and disabling psychiatric disorder with limited treatment options.  AUD is a chronic relapsing brain disease characterized by compulsive alcohol use, loss of control over alcohol intake, and a negative emotional state when not using alcohol.  According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), an estimated 16 million people in the U.S. have AUD and less than 10% receive treatment for the disease. There is a high unmet medical need for better treatments for AUD.

About MN-166 (ibudilast)

MN-166 has been marketed in Japan and Korea since 1989 to treat cerebrovascular disorders, including post-stroke complications, and bronchial asthma. MediciNova licensed MN-166 (ibudilast), from Kyorin Pharmaceutical in October 2004 for potential utility in relapsing remitting multiple sclerosis (RRMS). Intellectual property was additionally established by MediciNova in other neurological conditions. MN-166 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 including IL-1ß, TNF-a, and IL-6, and which upregulates the release of the anti-inflammatory cytokine IL-10 and neurotrophic factors such as NGF and GDNF. It attenuates the activation of brain glial cells in certain neurological conditions. Ibudilast's anti-neuroinflammatory and/or neuroprotective actions have been demonstrated in preclinical and clinical study results and provide the rationale for its therapeutic utility in alcohol- or opioid- or methamphetamine addiction, progressive MS, and chronic neuropathic pain.   MediciNova's development paths are firmly founded on issued method-of-use patents. A drug supply collaboration exists with Taisho Pharmaceutical Industries, Ltd., owned by Teva Pharmaceuticals.
