LA JOLLA, Calif., Aug. 25, 2014 (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 the FDA approval to initiate a clinical trial of MN-166 (ibudilast) in amyotrophic lateral sclerosis (ALS). The principal investigator of the study is Benjamin Rix Brooks, MD, Director, Carolinas Neuromuscular/ALS-MDA Center at Carolinas HealthCare System Neurosciences Institute in Charlotte, NC. The study is funded by MediciNova with the support of Carolinas HealthCare System.
The trial is a randomized, double-blind, placebo-controlled study which includes a six-month treatment period followed by a six-month open-label extension. The study will evaluate several efficacy endpoints including functional activity (ALSFRS-R), respiratory function, muscle strength, and non-invasive ventilation (NIV) utilization in addition to monitoring the safety and tolerability of MN-166 60 mg/day versus placebo when administered in combination with riluzole in subjects with ALS.
Dr. Benjamin Rix Brooks, principal investigator, commented, "We are excited to initiate this study of ibudilast which targets a disease with limited treatment options. Ibudilast has demonstrated attenuating effects on activated glia cells which are considered to play a key role in disease progression in ALS patients." Yuichi Iwaki, MD, PhD, President and Chief Executive Officer of MediciNova, Inc., commented, "We are very pleased to have successfully completed the FDA review period and look forward to initiating patient enrollment this fall. The safety and efficacy data from this trial will be important to our overall development efforts and should be complementary to efforts underway for proof-of-concept trials of MN-166 in progressive MS and drug addiction in the U.S." Dr. Iwaki further commented, "While MN-166 development is addressing unmet medical needs in all of its neurological indications, ALS may represent the largest unmet medical need."
About the ALS Trial
This is a single center, randomized, double-blind, placebo-controlled, 6-month study designed to evaluate the safety, tolerability and clinical endpoint responsiveness of MN-166 (60 mg/day) when administered as an adjunct to riluzole (100 mg/day) in subjects with amyotrophic lateral sclerosis (ALS). This study consists of two treatment arms, MN-166 and matching placebo, and randomization will occur in a 2:1 ratio (MN-166: placebo). To be eligible, subjects must have a diagnosis of sporadic or familial ALS with onset of less than 3 years from first clinical weakness prior to screening and must be on a stable dose of riluzole for at least 1 month prior to study drug treatment. A total of approximately 60 male and female subjects from 18 to 80 years old, inclusive will be enrolled (40 subjects in the MN-166 group; 20 subjects in the placebo group).
Upon completion of the Double-blind Phase, subjects randomized to the placebo arm will continue for an additional 6 months and will receive open-label MN-166. If there are no safety or tolerability concerns in the MN-166 treated group, a decision will be made to extend participation to the MN-166 treated group into the Open-Label Extension (OLE) Phase. Otherwise, only the placebo-treated patients will participate in the OLE Phase.
The primary objective is to evaluate the safety and tolerability of MN-166 60 mg/day versus placebo when administered for 6 months with riluzole in subjects with ALS. The secondary objective is to evaluate the clinical endpoint responsiveness of MN-166 60 mg/day versus placebo when administered with riluzole in subjects with amyotrophic lateral sclerosis as measured by the following assessments:
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. The nerves lose the ability to trigger specific muscles, which causes the muscles to become weak. As a result, ALS affects voluntary movement and patients in the later stages of the disease may become totally paralyzed. Life expectancy of an ALS patient is usually 2-5 years. According to the ALS Association, there are approximately 30,000 ALS patients in the U.S. and approximately 5,600 people in the U.S. are diagnosed with ALS each year. Riluzole is the only pharmaceutical treatment approved for ALS, but it has limited efficacy.
About MN-166 (ibudilast)
MN-166 (ibudilast) has been marketed in Japan and Korea since 1989 to treat cerebrovascular disorders, including post-stroke complications, and bronchial asthma. MediciNova licensed MN-166 (ibudilast), from Kyorin Pharmaceutical for potential utility in MS. Intellectual property was additionally established or obtained by MediciNova in progressive MS and other neurological conditions. MN-166 (ibudilast) is a first-in-class, orally bioavailable, small molecule phosphodiesterase (PDE) -4 and -10 inhibitor and a macrophage migration inhibitory factor (MIF) inhibitor that suppresses pro-inflammatory cytokines including IL-1ß, TNF-a, and IL-6, and which upregulates the release of the anti-inflammatory cytokine IL-10 and neurotrophic factors such as NGF and GDNF. It attenuates the activation of brain glial cells in certain neurological conditions. Ibudilast's anti-neuroinflammatory and/or neuroprotective actions have been demonstrated in preclinical and clinical study results and provide the rationale for its therapeutic utility in neurodegenerative diseases (i.e. progressive MS, ALS), substance abuse/addiction, and chronic neuropathic pain.
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, MN-221 for the treatment of acute exacerbations of asthma, and MN-001 for NASH and IPF. MN-166 is being developed in multiple indications, largely through investigator-sponsored trials and outside funding. MediciNova is engaged in strategic partnering discussions to support further development of its programs. For more information on MediciNova, Inc., please visit www.medicinova.com.
