LA JOLLA, Calif., March 06, 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 the presentation of results based on the completed study which evaluated the safety and efficacy of MN-166 (ibudilast) in opioid dependence at a symposium titled, “Glial and Neuroinflammatory Modulators for Attenuating Some Abuse-Related Effects of Drugs,” at the Behavior, Biology and Chemistry: Translational Research in Addiction Meeting held on March 5, 2016.
Sandra Comer, Ph.D., Professor, Department of Psychiatry, Columbia University and New York State Psychiatric Institute (NYSPI), presented results of the completed Phase 2 trial which evaluated MN-166 (ibudilast) in patients with opioid dependence.
Major highlights from the presentation, “Ibudilast for Treating Opioid Use Disorder: Laboratory Studies in Humans,” include the following:
- Ibudilast significantly decreased the reinforcing effects of oxycodone (p <0.05);
- Ibudilast significantly decreased craving for heroin (p <0.01), cocaine (p <0.01), and tobacco (p <0.05);
- Ibudilast significantly decreased participants’ rating for “liking” oxycodone (p <0.05);
- Ibudilast significantly enhanced the analgesic effects of oxycodone (p <0.05);
- Ibudilast was safe and well-tolerated by the participants.
In addition, Keith Heinzerling, M.D., M.P.H., Associate Professor, Department of Family Medicine and Medical Director of the UCLA Center for Behavioral and Addiction Medicine, presented at the plenary session the rationale for how MN-166 (ibudilast) may work as a treatment for patients with methamphetamine dependence.
Yuichi Iwaki, M.D., PhD, President and Chief Executive Officer of MediciNova, Inc., commented, "We are very pleased with the encouraging efficacy results reported in Dr. Comer’s study, particularly ibudilast’s ability to reduce the craving for heroin, and ibudilast’s positive safety and tolerability results reported at BBC. We are now considering the next step in the development process to further evaluate ibudilast’s potential utility in the treatment of opioid dependence.”
About the Opioid Dependence Clinical Trial
The study was a randomized, placebo-controlled, double-blind, inpatient Phase 2 study of MN-166 (ibudilast) in opioid-dependent abusers of prescription opioids and/or heroin. The study duration was approximately 6 weeks per subject. The crossover study design included initial detoxification followed by randomization to ibudilast 50 mg twice a day or placebo. Subjects were maintained on each dose for at least 2-3 consecutive weeks (1 week stabilization + 1.5 week testing). During test weeks, participants received oxycodone (0, 15, or 30 mg) in random order on separate days. For each dose, a sample followed by a choice session was completed. During the choice session, a “drug versus money” self-administration paradigm was employed. The primary aim of the study was to investigate the ability of MN-166 to alter the reinforcing, analgesic, subjective, performance, and physiological effects of oxycodone, a commonly abused prescription opioid.
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 for potential utility in relapse-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 ALS), substance abuse/addiction and chronic neuropathic pain.
MediciNova, Inc. is a publicly-traded biopharmaceutical company founded upon acquiring and developing novel, small-molecule therapeutics for the treatment of diseases with unmet medical needs with a commercial focus on the U.S. market. MediciNova's current strategy is to focus on MN-166 (ibudilast) for neurological disorders such as progressive MS, ALS and substance dependence (e.g., methamphetamine dependence, opioid dependence) and MN-001 (tipelukast) for fibrotic diseases such as nonalcoholic steatohepatitis (NASH) and idiopathic pulmonary fibrosis (IPF). MediciNova’s pipeline also includes MN-221 (bedoradrine) for the treatment of acute exacerbations of asthma and MN-029 (denibulin) for solid tumor cancers. MediciNova is engaged in strategic partnering and other potential funding discussions to support further development of its programs.
