Brief Summary:

A drug called AV650 (tolperisone HCl) will be given to patients who have spasticity following a spinal cord injury. This study has three purposes:

  1. To determine whether AV650 is safe for patients with spinal cord injury;
  2. To assess what the body does with AV650 once it is ingested; and,
  3. To gather some early evidence as to whether AV650 is effective in treating spasticity in patients with spinal cord injury.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 120 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
