Safety and Preliminary Effectiveness of AV650 in Patients With Spasticity Due to Spinal Cord Injury
AV650-014: A Four Week, Prospective, Randomized, Double Blind, Placebo-Controlled Trial to Assess Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of AV650 in Patients With Spasticity Due to Spinal Cord Injury

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.
