LA JOLLA, Calif., July 27, 2022 (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 that it has received a Notice of Allowance from the Korean Intellectual Property Office for a pending patent application which covers MN-001 (tipelukast) and MN-002 (a major metabolite of MN-001) for the treatment of fibrosis which includes a wide range of fibrotic diseases.

Once issued, the patent maturing from this allowed patent application is expected to expire no earlier than June 2035. The allowed claims cover a composition for inhibiting or treating fibrosis, excluding pulmonary fibrosis and certain types of hepatic fibrosis, using MN-001 or MN-002. The allowed claims specifically cover a long list of fibrotic indications including but not limited to Crohn's Disease, cystic fibrosis of the pancreas and lungs, fibrotic complications of surgery or injection fibrosis, macular degeneration, renal fibrosis, scarring after surgery, uterine fibrosis, viral hepatitis induced fibrosis, and alcoholic liver damage induced liver fibrosis. The allowed claims cover oral administration, including tablets and capsules, and liquid dosage forms. The allowed claims cover a wide range of doses of MN-001 (tipelukast) and MN-002 and a range of different dosing frequencies.

Kazuko Matsuda, M.D. Ph.D., MPH., Chief Medical Officer, MediciNova, Inc., commented, “We are very pleased to receive notice that this new patent will be granted as the claims are broad enough to cover MN-001 for the treatment of many forms of fibrosis and fibrotic disease. A similar patent that covers the treatment of various forms of fibrosis and fibrotic disease has already been granted by the U.S. Patent Office and the Japan Patent Office. We believe this patent could substantially increase the potential value of MN-001 as MN-001’s broad anti-fibrotic activity enables us to pursue clinical development in various types of fibrosis.”

About MN-001

MN-001 (tipelukast) is a novel, orally bioavailable, small molecule compound thought to exert its effects through several mechanisms to produce its anti-inflammatory and anti-fibrotic activity in preclinical models, including leukotriene (LT) receptor antagonism, inhibition of phosphodiesterases (PDE) (mainly 3 and 4), and inhibition of 5-lipoxygenase (5-LO). The 5-LO/LT pathway has been postulated as a pathogenic factor in fibrosis development, and MN-001's inhibitory effect on 5-LO and the 5-LO/LT pathway is considered to be a novel approach to treat fibrosis. MN-001 has been shown to down-regulate expression of genes that promote fibrosis including LOXL2, Collagen Type 1 and TIMP-1. MN-001 has also been shown to down-regulate expression of genes that promote inflammation including CCR2 and MCP-1. In addition, histopathological data shows that MN-001 reduces fibrosis in multiple animal models.
