MediciNova to Present Additional Clinical Data Demonstrating Potential Neuroprotection Benefits of MN-166 in Multiple Sclerosis At the 18th Meeting of the European Neurological Society


SAN DIEGO, April 2, 2008 (PRIME NEWSWIRE) -- MediciNova, Inc., a biopharmaceutical company that is publicly traded on the Nasdaq Global Market (Nasdaq:MNOV) and the Hercules Market of the Osaka Securities Exchange (Code Number: 4875), today announced that it will present additional data from a double-blind analysis of the first year of treatment from its two-year Phase II clinical trial of MN-166, a novel, orally administered compound being evaluated for the treatment of multiple sclerosis (MS), at the 18th Meeting of the European Neurological Society to be held in Nice, France from June 7 to 11, 2008.

The new data shows that MN-166 significantly decreased the progression of new inflammatory lesions to persistent black holes (permanent brain lesions believed to indicate the death of nerves in the brain) on magnetic resonance imaging (MRI) in MS patients, adding support to MediciNova's belief that MN-166 may provide neuroprotection in relapsing MS. Study results will be described in the following oral presentation:

           166-CL-001 Investigators

About MediciNova

MediciNova, Inc. is a publicly-traded biopharmaceutical company focused on acquiring and developing novel, small-molecule therapeutics for the treatment of diseases with unmet need with a specific focus on the U.S. market. Through strategic alliances primarily with Japanese pharmaceutical companies, MediciNova is developing 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 assets having claims of commercially adequate scope. MediciNova's pipeline includes six clinical-stage compounds for the treatment of status asthmaticus, multiple sclerosis, 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 its resources on the development and commercialization of two prioritized assets in its development pipeline: MN-221 for the treatment of status asthmaticus, an acute, severe asthma attack, and MN-166 for the treatment of multiple sclerosis. MediciNova will seek to monetize its other product candidates at key value inflection points. For more information on MediciNova, Inc., please visit www.medicinova.com.
