SAN DIEGO, Feb. 1, 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 additional data from a double-blind analysis of the first year of treatment from its two-year Phase II clinical trial of MN-166 in multiple sclerosis (MS). The second year of the Phase II clinical trial is on-going with results expected in April 2008. The analysis showed that MN-166 decreased the formation of 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.
