SAN DIEGO, Nov. 18, 2012 (GLOBE NEWSWIRE) -- 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 it has received Notices of Allowance from the European Patent Office (EPO) for two pending patent applications. One covers the use of ibudilast (MN-166) in drug addiction and the other provides for ibudilast use to enhance opioid analgesia in acute pain settings. MN-166 is the company's lead drug development candidate for certain neurological conditions, including progressive multiple sclerosis, drug addiction, and pain.

"Along with our recent EPO allowance for the use of ibudilast in progressive multiple sclerosis, these drug addiction and pain patent allowances solidify our exclusivity in that region for all the core development areas of the MN-166 program," noted Kirk Johnson, PhD, Chief Scientific Officer and co-inventor.

A patent maturing from the allowed application for drug addiction is expected to expire no earlier than 2026 and is a counterpart of an issued U.S. patent expiring no earlier than 2030. The patent application related to the use of ibudilast in acute pain conditions resulted from collaborative pre-clinical studies with renown pain researchers at the University of Colorado, Boulder, including Linda R. Watkins, PhD, Professor of Psychology and the Center for Neuroscience. It includes claims covering the use of ibudilast or phosphodiesterase (PDE) - 4 inhibitors to treat or prevent acute pain in combination with opioids like morphine or oxycodone and expires no earlier than 2028.

"We are very pleased with this advancement in our patent portfolio and its contribution to our European-focused development and overall business plan for MN-166," noted Yuichi Iwaki, M.D., Ph.D., President and Chief Executive Officer of MediciNova.

About Ibudilast

Ibudilast has been used in asthma and post-stroke disorders in Japan for around 20 years. MediciNova has demonstrated the potential utility of ibudilast in the treatment of neurological disorders at higher doses with encouraging outcomes in company-sponsored clinical trials in multiple sclerosis (MS) and neuropathic pain. MediciNova's priorities include pursuing Phase 2 proof-of-concept trials of ibudilast for the treatment of progressive MS and/or neuropathic pain through non-dilutive funding. Additionally, MediciNova's collaborative clinical development is proceeding well with drug addiction investigators at organizations like Columbia/NYSPI and UCLA and the funding of Phase 2 trials via the National Institute on Drug Abuse (NIDA) for the use of ibudilast to treat both opioid and methamphetamine addiction. A Phase 2a investigator-sponsored trial of ibudilast in the treatment of chronic medication overuse headache (MOH) pain is also ongoing in Australia.

About MediciNova

MediciNova, Inc. is a publicly traded biopharmaceutical company founded upon acquiring and developing novel, small-molecule therapeutics for the treatment of diseases with unmet need with a commercial focus on the U.S. market. Through strategic alliances primarily with Japanese pharmaceutical companies, MediciNova holds rights to a diversified portfolio of clinical and preclinical product candidates, each of which MediciNova believes has a well-characterized and differentiated therapeutic profile, attractive commercial potential, and patent coverage of commercially adequate scope. MediciNova's pipeline includes six clinical-stage compounds for the treatment of acute exacerbations of asthma, chronic obstructive pulmonary disease exacerbations, multiple sclerosis and other neurologic conditions, asthma, interstitial cystitis, solid tumor cancers, generalized anxiety disorder, preterm labor and urinary incontinence and two preclinical-stage compounds for the treatment of thrombotic disorders. MediciNova's current strategy is to focus on its two prioritized product candidates, MN-221, for the treatment of acute exacerbations of asthma and chronic obstructive pulmonary disease exacerbations, and ibudilast (MN-166) for neurological disorders. MN-221 is involved in clinical trials under U.S. INDs. MN-166 is being developed in Phase 1b/2 trials for pain and drug addiction, largely through Investigator INDs and outside funding. Proof-of-concept Phase 2b trial(s) in Progressive MS are pending. MediciNova is engaged in strategic partnering and consortium funding discussions to support further development of both the MN-221 and ibudilast/MN-166 programs. Additionally, MediciNova will seek to monetize opportunistically its other pipeline candidates. For more information on MediciNova, Inc., please visit
