MediciNova Announces Abstract Regarding The Mechanism By Which MN-001 (tipelukast) Alters Triglyceride Metabolism Accepted For Presentation At The 19th International Symposium On Atherosclerosis (ISA2021)

LA JOLLA, Calif., Oct.

LA JOLLA, Calif., Oct. 21, 2021 (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 an abstract entitled "MN-001 (tipelukast) reduces triglycerides levels in hepatocytes by down-regulating fatty acid translocase/CD36 expression" has been selected for presentation at the 19th International Symposium on Atherosclerosis (ISA2021) to be held October 24 - 27, 2021 in a hybrid format both online and onsite at the Kyoto International Conference Center in Kyoto, Japan.

This study showed that MN-001 (tipelukast) inhibited the uptake of arachidonic acid into hepatocytes and suppressed the synthesis and accumulation of triglycerides (TG) in hepatocytes. These phenomena, which are consistent with earlier findings, suggested that MN-001 (tipelukast) reduced the synthesis and accumulation of TG in hepatocytes by suppressing the expression of CD36.

MediciNova's research collaborator, Dr. Masatsune Ogura, Associate Professor at the Department of General Medical Science, Chiba University Graduate School of Medicine, will present the results of the study. Dr. Ogura's e-presentation with narration will be accessible on the ISA2021 website from October 25 to November 30, 2021.

Kazuko Matsuda, M.D. Ph.D, MPH., Chief Medical Officer, MediciNova, Inc., commented, "It has been observed that MN-001 treatment reduces serum TG levels in multiple previous clinical trials. Particularly, in a Phase 2 clinical trial with hypertriglyceridemia subjects with NASH or NAFLD, MN-001 demonstrated a clinically meaningful and statistically significant reduction in mean serum TG with no safety or tolerability issues. We are very pleased that Dr. Ogura will present new findings regarding the mechanism by which MN-001 alters intracellular triglyceride metabolism."

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.

About MediciNova

MediciNova, Inc. is a clinical-stage biopharmaceutical company developing a broad late-stage pipeline of novel small molecule therapies for inflammatory, fibrotic, and neurodegenerative diseases. Based on two compounds, MN-166 (ibudilast) and MN-001 (tipelukast), with multiple mechanisms of action and strong safety profiles, MediciNova has 11 programs in clinical development. MediciNova's lead asset, MN-166 (ibudilast), is currently in Phase 3 for amyotrophic lateral sclerosis (ALS) and degenerative cervical myelopathy (DCM) and is Phase 3-ready for progressive multiple sclerosis (MS). MN-166 (ibudilast) is also being evaluated in Phase 2 trials in glioblastoma, patients at risk of developing acute respiratory distress syndrome (ARDS), and substance dependence. MN-001 (tipelukast) was evaluated in a Phase 2 trial in idiopathic pulmonary fibrosis (IPF) and is in preparation for a second Phase 2 trial in nonalcoholic steatohepatitis (NASH). MediciNova has a strong track record of securing investigator-sponsored clinical trials funded through government grants.
