Mitsubishi Tanabe Pharma Corporation Presents Edaravone Clinical Trial Data in ALS at 2016 American Academy of Neurology Annual Meeting
Mitsubishi Tanabe Pharma Corporation (President & Representative Director: Dr. Masayuki Mitsuka) has presented th results from a Phase 3 study of edaravone (MCI-186) in amyotrophic lateral sclerosis (ALS) at the 68 Annual Meeting of the American Academy of Neurology in Vancouver, British Columbia. The MCI-186 19 study met its primary efficacy endpoint of mean change in the ALS Functional Rating Scale-Revised (ALSFRS-R) at 24 weeks with a frequency of adverse events similar to placebo.
“Helping patients enjoy healthier lives is what inspires and motivates us. We recognize the challenges patients and their families face with rare medical conditions such ALS and are encouraged by these results.” said Joseph M. Palumbo, MD, Vice President, Head of Clinical Research, Mitsubishi Tanabe Pharma Development America, Inc.
Mitsubishi Tanabe Pharma Corporation was awarded Orphan Drug Designation for edaravone by the U.S. Food and Drug Administration in May 2015 and the European Medicines Agency in June 2015. It is not currently approved for use in either region.
Edaravone (MCI-186) has been studied in Japan for the treatment of ALS. It has not been investigated in the U.S. It i, ii is believed to relieve effects of oxidative stress – a likely key factor in the onset and progression of ALS.i,ii Oxidative stress is thought to be an imbalance between the production of free radicals (unpaired, reactive electrons) and the ability of the body to counteract or detoxify their harmful effects.iii In patients with ALS, there are consistent increases in oxidative stress biomarkers.iii
ALS, also known as Lou Gehrig’s disease, is a rapidly progressive neurological disease in which patients die, on average, within 3 to 5 years from onset of symptoms.iv ALS attacks the nerve cells responsible for controlling voluntary muscles, such as those in the arms, legs and respiratory tract.i It is one of the most well-known neuromuscular diseases, affecting approximately two in 100,000 people worldwide.i,v While a hereditary form of vi the disease, familial ALS, accounts for 5%–10% of cases, the majority of ALS cases do not have a definitive cause.vi
