MediciNova Announces First Advanced ALS Patient Using Non-Invasive Ventilation Support Enrolled in Phase 2 Clinical Trial of MN-166 (ibudilast)


LA JOLLA, Calif., Sept. 2, 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 that the first advanced ALS patient, using non-invasive ventilation (NIV), has enrolled in the Phase 2 clinical trial evaluating MN-166 (ibudilast) in both early and advanced stage ALS. MediciNova amended the protocol to expand its recruitment to include advanced ALS patients in the trial, and this amendment was approved by FDA (U.S. Food and Drug Administration). The amended protocol now plans enrollment of 60 advanced ALS patients with NIV support in the study in addition to 60 patients without NIV support. Dr. Benjamin Rix Brooks, Director, Carolinas HealthCare System's Neuromuscular/ALS-MDA Center, is the Principal Investigator of the study.

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, which allows us to enroll the first advanced ALS patient with NIV support. The safety and efficacy data from advanced ALS patients will be important for our development efforts in ALS and is complementary to the ongoing study that is enrolling ALS patients who are not using NIV."

About the Study Design

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 ALS. The protocol amendment plans for an additional 60 advanced ALS patients, who are on NIV support, to be enrolled in the study. 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 10 years from first clinical weakness prior to screening, may be on NIV support, and must be on a stable dose of riluzole for at least 1 month prior to study drug treatment. A total of approximately 120 male and female subjects from 18 to 80 years old, inclusive, will be enrolled (80 subjects in the MN-166 group; 40 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. The secondary objective is to evaluate the clinical endpoint responsiveness of MN-166 60 mg/day versus placebo when administered with riluzole as measured by the following assessments:

  • Functional activity as assessed by the Amyotrophic Lateral Sclerosis Functional Rating Scale-revised (ALSFRS-R)
  • Respiratory function as measured by slow vital capacity (SVC), Maximum Inspiratory Pressure (MIP) also known as Negative Inspiratory Force (NIF) and Forced Expiratory Volume in 1 second (FEV1) measured under SVC protocol
  • Muscle strength measured by manual muscle testing (MMT) and instrumented hand grip dynamometry

About ALS

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 post-stroke complications and bronchial asthma. MediciNova licensed MN-166 (ibudilast) from Kyorin Pharmaceutical Co., Ltd. for potential utility in RRMS. 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 and promotes neurotrophic factors. It attenuates activated glia cells, which play a major role in certain neurological conditions. Ibudilast's anti-neuroinflammatory and neuroprotective actions have been demonstrated in preclinical and clinical study results and provide the rationale for its therapeutic utility in neurodegenerative diseases (e.g., progressive MS and ALS), substance abuse/addiction and chronic neuropathic pain.

About MediciNova

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.
