MediciNova (MNOV) Receives Notice of Allowance for MS-Treatment Ibudilast Patent

February 1, 2012 6:40 AM EST
MediciNova Inc, (Nasdaq: MNOV), announced that it has received a Notice of Allowance from the U.S. Patent and Trademark Office for a pending patent application, which covers the use of ibudilast for the treatment of progressive forms of multiple sclerosis. Ibudilast (MN-166), is the company's lead drug development candidate for certain neurological conditions, including progressive multiple sclerosis, neuropathic pain, and drug addiction.

A patent maturing from this allowed patent application is expected to expire no earlier than early 2029 and covers a method of treating primary progressive multiple sclerosis (PPMS) or secondary progressive MS (SPMS) by administering ibudilast either alone or in combination with other drugs. The patent application is based upon clinical investigations conducted by MediciNova researchers which showed an apparent disease-modifying benefit in which brain volume loss, or brain atrophy, commonly associated with disease progression, was reduced by oral administration of ibudilast to a group of multiple sclerosis patients including some subjects with progressive multiple sclerosis, in a dose-related fashion over at least a 10-month treatment period.
