MediciNova Receives a Notice of Intention to Grant for a New Patent Covering MN-001 and MN-002 for the Treatment of Advanced NASH in Europe - Seite 2

The molecular mechanism of action of MN-001 (tipelukast) includes leukotriene receptor antagonism and inhibition of phosphodiesterase (mainly 3 and 4) and 5-lipoxygenase (5-LO) and these multiple mechanisms are believed to reduce inflammation and prevent fibrosis. We have also confirmed that MN-001 (tipelukast) suppresses fibrosis-promoting genes such as LOXL2, Collagen Type 1, and TIMP-1 and suppresses inflammation-promoting genes such as CCR2 and MCP-1 in a fibrosis disease model study. Although the direct mechanism of action of MN-001 (tipelukast) on TG reduction in blood has not yet been fully clarified, we are conducting joint research with Juntendo University with the aim of elucidating this mechanism of action.

In various animal models of fibrosis disease, MN-001 (tipelukast) has been shown to improve fibrosis on histopathological examination, and the FDA has granted Fast Track status to MN-001 (tipelukast) for the treatment of NASH with fibrosis. MN-001 (tipelukast) has also been granted Fast Track status and Orphan Drug designation for the treatment of idiopathic pulmonary fibrosis. In the past, we have conducted clinical trials for MN-001 (tipelukast) for the treatment of bronchial asthma and interstitial cystitis, and more than 600 patients have been treated with MN-001 (tipelukast) to date, confirming its good safety and tolerability profile.  

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 and substance dependence. MN-001 (tipelukast) was evaluated in a Phase 2 trial in idiopathic pulmonary fibrosis (IPF) and a second Phase 2 trial in non-alcoholic fatty liver disease (NAFLD) is ongoing. MediciNova has a strong track record of securing investigator-sponsored clinical trials funded through government grants.
