Study Summary

The purpose of this study is to compare the efficacy and safety of intravenous (IV) infusions of MT-3921 to placebo in subjects with acute traumatic cervical spinal cord injury. Subjects meeting eligibility criteria will enter the 6-month double-blind period. Subjects will be randomized in a 2:1 ratio to receive MT-3921 or placebo in a double blind manner.

Primary Outcome

The UEMS is a subscore of the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) that focuses selectively on function of 5 key muscles in the upper limbs. UEMS ranges from 0 to 50 points, where a higher score indicates a better movement.
