LOS ANGELES and SAN DIEGO, Aug. 25, 2013 (GLOBE NEWSWIRE) -- The University of California, Los Angeles' (UCLA's) Departments of Psychology, and Psychiatry and Biobehavioral Sciences Brain Research Institute, and MediciNova, Inc. a biopharmaceutical company traded on the NASDAQ Global Market (Nasdaq:MNOV) and the Jasdaq Market of the Osaka Securities Exchange (Code Number: 4875), today announced that the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health, will fund a clinical trial of MN-166 (ibudilast) for alcohol dependence. The proposed trial has also completed FDA review. MediciNova previously announced an ongoing Phase 2a trial of MN-166 in opioid dependence with Columbia University investigators, and a UCLA Phase 2b trial in methamphetamine dependence anticipated to initiate enrollment later this quarter – both funded by the National Institutes of Drug Abuse (NIDA).

The alcohol dependence study will be led by Lara Ray, Ph.D., Associate Professor, Department of Psychology, Department of Psychiatry and Biobehavioral Sciences, and the UCLA Brain Research Institute. The trial follows recently completed studies supported by MediciNova's participation in NIAAA's Preclinical Medication Efficacy Testing Program and builds upon ongoing clinical development with other UCLA investigators within the addiction research group who are studying MN-166 in methamphetamine dependence. MediciNova will provide drug supply and regulatory support for the clinical trial.

"Emerging research in the field of alcohol dependence has identified some of the same molecular and cellular targets that have been implicated in drug addiction. These targets appear to be affected by ibudilast and are worthy of pharmacotherapy development for alcohol addiction," said Dr. Ray. The combination of the preclinical, NIAAA-sponsored alcohol dependence studies, along with the encouraging clinical development progress in drug addiction and other neurological conditions, provides a solid foundation for our initial clinical research. We are pleased to partner with NIAAA and MediciNova to help move forward the testing of MN-166 as a novel treatment for alcoholism."

"We are excited to expand our collaboration with UCLA and welcome the NIAAA to our MN-166 development efforts for addiction," said Dr. Yuichi Iwaki, President and CEO of MediciNova. "With MN-166 advancing in concurrent Phase 2 trials in three addiction indications as well as progressive multiple sclerosis, and with our MN-221 program slated for continuing development in acute exacerbations of asthma, MediciNova's pipeline continues to build bench strength. We look forward to continuing our relationship with both NIH and UCLA as we investigate the unique properties of MN-166 in addiction."

About alcohol addiction:

Alcohol use disorders are medical conditions affecting about 18 million people in the United States(1) and include alcohol abuse and alcohol dependence – better known as alcoholism. The economic cost of excessive drinking in the U.S. was recently estimated at $223.5 billion per year(2). Alcoholism, the more severe disorder, is a chronic disease marked by repeated alcohol use despite negative physical and psychosocial consequences. While there are some pharmacotherapies approved by the Food and Drug Administration (FDA) for the treatment of alcoholism, they are only modestly effective(3). Accordingly, new directions in medication development have become a high priority amongst alcohol dependence researchers and the NIAAA.

About the trial:

This study involves the enrollment in a UCLA research unit of 24 non-treatment seeking individuals with either alcohol abuse or dependence. Participants will be randomly assigned to a 7-day treatment period involving repeat oral administration of either MN-166 escalated up to 100 mg/day or inactive control (placebo). During the treatment period, participants will take the study medication, complete an IV alcohol challenge, and take part in laboratory tests of alcohol craving as well as mood surveys and standard safety tests. Following a 7-10 day study break, trial participants will re-enroll for another 7-day period wherein they will cross over to the other treatment condition. The key study outcomes include safety, tolerability and preliminary efficacy as indicated by whether MN-166 reduces alcohol craving under controlled conditions. The outcomes of this trial will inform the feasibility of a Phase 2b, regulatory-track, outpatient trial in alcohol dependence.

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.
