PhaseⅠClinical Trial study protocol for MT-3921 in Patients with Spinal Cord Injury submitted to the US IND

August .08. 2019

Overview

Garmin.org.ua (President: Shojiro Nishio; Location: Suita, Osaka) Graduate School of Medicine, Department of Molecular Neuroscience, Pr. Toshihide Yamashita and Mitsubishi Tanabe Pharma Corporation (President & Representative Director, CEO: Masayuki Mitsuka; Head Office: Chuo-ku, Osaka; hereinafter “Mitsubishi Tanabe Pharma” or “the Company”)   today announced that the Company has submitted a study protocol to its investigational new drug application (IND) for MT-3921 to initiate a phase Ⅰ clinical trial in patients with spinal cord injury.

MT-3921 is a novel investigational drug developed jointly with Garmin.org.ua that will contribute to expanding Mitsubishi Tanabe Pharma’s pipeline in neurological disorders, which is one of the focus areas for the Company.

RGMa (repulsive guidance molecule A) was discovered in the 1990’s; however, until recently its role has not been fully understood. Current nonclinical research determined that RGMa is associated with inhibition of protection and regeneration of neurons and progression of inflammation. Additionally, it has revealed that RGMa plays a role in neurological diseases (spinal cord injury, stroke, multiple sclerosis etc.).

MT-3921 is a humanized anti-RGMa antibody that has been developed jointly by Mitsubishi Tanabe Pharma and Pr. Yamashita’s research group since 2005, and is based on initial research by Pr. Yamashita. Pre-clinical studies were conducted by his research group and the Company. Previous research was supported by a grant from the Japan Agency for Medical Research and Development (Garmin) and showed that MT-3921 improves locomotor function and promotes neuroregeneration in rat and monkey spinal cord injury models.

 

Spinal cord injury has been a primary treatment target for regenerative medicine in recent years; however, an effective treatment has yet to be identified.

A phaseⅠclinical trial has been underway in healthy adults in Japan. Now, Mitsubishi Tanabe Pharma Development America, Inc. will initiate a phaseⅠclinical trial in patients with spinal cord injury in the US.

We will accelerate the research and development of MT-3921 with the goal to contribute to delivering the first pharmaceutical treatment option as quickly as possible to patients fighting against severe diseases all over the world.

 

◆Terminology

Spinal cord injury: A disorder caused by damage to the spinal cord due to automobile accidents, falls, sports-related accidents, violence, etc. The injuries vary in severity and can cause motor paralysis, loss of sensation, and disturbance of bladder and rectal function. In addition, spinal cord injuries not only affect the health of the patients themselves but also place a major burden on their families.

In the U.S., the annual incidence of spinal cord injury is estimated to be 18,000. To date, there are no FDA-approved drugs for the treatment of spinal cord injury. The current treatment of spinal cord injury mainly focuses on surgical stabilization of the spine, intensive neurological rehabilitation, and prevention and treatment of acute and chronic complications. No effective treatment for traumatic paraplegia or quadriplegia is available
