LA JOLLA, Calif., Nov. 19, 2015 (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 it is initiating a clinical trial to investigate MN-001 (tipelukast) for the treatment of hypertriglyceridemia in NASH patients. The principal investigator is Paul J. Pockros, MD, Division Head of Gastroenterology and Hepatology at Scripps Clinic, and the trial will be primarily conducted at U.S. medical centers within SC Liver Research Consortium (SCLRC), an organization of hepatology and gastroenterology clinical research specialists which includes Scripps Clinic, University of Washington Medical Center, University of California San Diego, and Cleveland Clinic.
Yuichi Iwaki, MD, PhD, President and Chief Executive Officer of MediciNova, Inc., commented, "We are very pleased to initiate this trial which will enroll patients at leading U.S. medical centers to target NASH patients with hypertriglyceridemia. The trial could be completed within a relatively short time period and the primary endpoints are subject to objective measurement. We believe MN-001's anti-fibrotic and anti-inflammatory properties combined with its potential to reduce triglyceride levels in NASH patients offers a novel approach to the treatment of NASH.”
About the Trial
The Phase 2a trial is a multi-center (potentially up to 5 sites), proof-of-principle, open-label study designed to evaluate the efficacy, safety, and tolerability of MN-001 in subjects with non-alcoholic steatohepatitis (NASH) with hypertriglyceridemia. Eligible subjects will consist of males and females ranging in age from 21 to 65 years old, inclusive. To be eligible, subjects must have a histologically confirmed diagnosis of NASH and an elevated serum triglyceride (>150 mg/dL) during the Screening Phase. Approximately twenty (20) qualifying subjects will be given MN-001 250 mg orally administered once a day for the first 4 weeks and will be given MN-001 250 mg twice a day for an additional 8 weeks. Overall, the study timeline consists of a Screening Phase (up to 4 months) followed by a Treatment Phase (12 weeks), and a Follow-up visit (within 1 week after the last dose).
The primary efficacy endpoints of the study are to evaluate the effect of MN-001 on 1) triglyceride levels in NASH subjects with hypertriglyceridemia, and 2) cholesterol efflux capacity in NASH subjects with hypertriglyceridemia. Secondary endpoints include safety and tolerability of MN-001, PK profile of MN-001/MN-002 (by-product of MN-001), effects of MN-001 on HDL-C, LDL-C, and total cholesterol level, and effects of MN-001/002 on liver enzymes and percent fat in liver at Week 12.
FDA (U.S. Food and Drug Administration) has approved the protocol for this clinical trial of MN-001 (tipelukast) for the treatment of hypertriglyceridemia in NASH patients. Importantly, due to safety data from previous clinical studies of MN-001, FDA agreed that MediciNova may proceed with a Phase 2 study as the first clinical trial of MN-001 in NASH patients with hypertriglyceridemia.
FDA has granted Fast-Track designation to MN-001 for the treatment of NASH with fibrosis. Fast Track is a process designed to facilitate the development and expedite the review of drugs that are intended to treat serious or life-threatening diseases and demonstrate the potential to address unmet medical needs for such diseases. An important feature of the FDA's Fast Track program is that it emphasizes frequent communication between the FDA and the sponsor throughout the entire drug development and review process to improve the efficiency of product development. Accordingly, Fast Track status can potentially lead to a shortened timeline to ultimate drug approval.
About Non-alcoholic Steatohepatitis
Nonalcoholic steatohepatitis (NASH) is a condition in which there is fat in the liver along with inflammation and damage to liver cells. NASH is a common liver disease that resembles alcoholic liver disease but occurs in people who drink little or no alcohol. According to the U.S. National Digestive Diseases Information Clearinghouse (NDDIC), NASH prevalence in the U.S. is 2-5%, and an additional 10-20% of Americans have "fatty liver." The underlying cause of NASH is unclear, but it most often occurs in persons who are middle-aged and overweight or obese. Many patients with NASH have elevated serum lipids, diabetes or pre-diabetes. Progression of NASH can lead to liver cirrhosis. Liver transplantation is the only treatment for advanced cirrhosis with liver failure. At this time, there is no treatment for NASH.
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.
In addition to granting MN-001 Fast-Track designation for the treatment of NASH with fibrosis, the FDA has also granted MN-001 Orphan-Drug status and Fast-Track designation for treatment of idiopathic pulmonary fibrosis (IPF).
Previously, MediciNova evaluated MN-001 for its potential clinical efficacy in asthma and had positive Phase 2 study results. MN-001 has been exposed to more than 600 subjects and is considered generally safe and well-tolerated.
MediciNova, Inc. is a publicly-traded biopharmaceutical company founded upon acquiring and developing novel, small-molecule therapeutics for the treatment of diseases with unmet medical needs with a commercial focus on the U.S. market. MediciNova's current strategy is to focus on MN-166 (ibudilast) for neurological disorders such as progressive MS, ALS and substance dependence (e.g., methamphetamine dependence and opioid dependence), and MN-001 (tipelukast) for fibrotic diseases such as nonalcoholic steatohepatitis (NASH) and idiopathic pulmonary fibrosis (IPF). MediciNova’s pipeline also includes MN-221 (bedoradrine) for the treatment of acute exacerbations of asthma and MN-029 (denibulin) for solid tumor cancers. MediciNova is engaged in strategic partnering and other potential funding discussions to support further development of its programs.
