Mitsubishi Tanabe Pharma America Announces the Global Phase 3 Study of Oral Edaravone for ALS has Completed Enrollment


JERSEY CITY, N.J., Nov. 9, 2020 /PRNewswire/ -- Mitsubishi Tanabe Pharma Corporation (MTPA) today announced that patient enrollment has been completed for the global Phase 3 open-label study evaluating the long-term safety and tolerability of an investigational oral suspension formulation of edaravone (MT-1186) in patients with amyotrophic lateral sclerosis (ALS). The study is sponsored by Mitsubishi Tanabe Pharma Development America, Inc. (MTDA).

"Mitsubishi Tanabe Pharma group companies are committed to the fight against ALS, and reaching this milestone is a demonstration of our dedication to supporting the ALS community," said Atsushi Fujimoto, President, MTPA. "We are grateful to the participants, the investigators and the clinical staff at the study sites as well as the MTDA staff working on this study. With this oral edaravone Phase 3 study now fully enrolled, we are one step closer to reaching our goal of having an additional treatment option for patients."

The global multi-center, open-label study (MT-1186-A01), is evaluating approximately 185 ALS patients across approximately 50 sites in the U.S., Canada, Europe and Japan over the course of 48 weeks of treatment. After a screening, study participants (18 to 75 years of age) receive oral edaravone at a dose designed to deliver the therapeutic equivalent of the IV formulation of RADICAVA® (edaravone) approved by the U.S. Food and Drug Administration in 2017.

"ALS is a devastating, debilitating disease, and I am very pleased to be involved in this important research," said Angela Genge, M.D., FRCP (c), Executive Director, Clinical Research Unit, and Director, ALS Clinic, Montreal Neurological Institute-Hospital, who is a principal investigator for North America. "The completion of enrollment for the study is a crucial step in our efforts to explore potential treatment options for these patients."

About MT-1186
MT-1186 is an investigational oral formulation of edaravone being studied in patients with amyotrophic lateral sclerosis (ALS). Edaravone was discovered and developed by researchers together with Mitsubishi Tanabe Pharma Corporation (MTPC), headquartered in Osaka, Japan. In May 2019, MTP group companies completed a series of Phase 1 studies administering the oral suspension and intravenous formulations of edaravone in healthy volunteers. In addition to the current MT-1186-A01 Phase 3 study, MTDA also has other oral edaravone studies in development, including an extension study, MT-1186-A03, to explore patient safety after 96 weeks of edaravone administration. More information is available at (NCT04165824 and NCT04577404).

Postmarketing Commitment Study
An additional study, MT-1186-A02, which is a postmarketing commitment for the IV RADICAVA product, also will explore daily dosing of oral edaravone in ALS patients. MT-1186-A02 is not planned to be included with the initial New Drug Application (NDA) submission for orally administered edaravone. More information is available at (NCT04569084).
