InVivo Therapeutics Announces Positive Motor Recovery Assessments In Two Patients In The INSPIRE Study Of The Neuro-Spinal Scaffold

CAMBRIDGE, Mass.--(BUSINESS WIRE)--InVivo Therapeutics Holdings Corp. (NVIV) today announced that two patients in the INSPIRE study of the Neuro-Spinal Scaffold have improved from sensory incomplete AIS B spinal cord injury (SCI) to motor incomplete AIS C SCI in their most recent INSPIRE assessments. These are the second and third patients in the INSPIRE study to have reached AIS C motor incomplete classification.

One of these patients was enrolled in May 2016 and converted from complete AIS A SCI to incomplete AIS B SCI at the three-month exam in August 2016. At the 12-month visit, the patient regained motor function associated with the most sacral segments of the spinal cord and was assessed to be AIS C. Stuart Lee, M.D., is the Principal Investigator at Vidant Medical Center in Greenville, North Carolina, where this patient was implanted with the Neuro-Spinal Scaffold.

Dr. Lee said, “The patient’s continued improvement at the one year exam is encouraging. Return of sacral motor function may be related to improvements in bowel and bladder function that can have an appreciable impact on a patient’s quality of life. We look forward to monitoring this patient’s recovery and hope for continued progress.”

The second patient was enrolled in June 2015 and converted from complete AIS A SCI to incomplete AIS B SCI at the one-month exam in July 2015. At the 24-month per protocol ISNCSCI exam (see About the ISNCSCI Exam below), the patient was assessed to be AIS C with the ability to contract two muscles of one leg. The motor function was not noted in a separate medical evaluation earlier in the day that did not include a full ISNCSCI exam. Domagoj Coric, M.D., of Carolina Neurosurgery and Spine Associates, and William Bockenek, M.D., of Carolinas Rehabilitation, are Co-principal Investigators at the site where this patient was implanted.

Dr. Bockenek said, “This patient moved from AIS A to AIS B shortly after the initial injury and implantation with the Neuro-Spinal Scaffold two years ago, and now is noted on the ISNCSCI exam to have moved to an AIS C based on trace movements in one leg. Though the clinical significance of this change is unknown at this time, we remain cautiously optimistic that there may be a possibility for additional changes.”

InVivo CEO and Chairman Mark Perrin said, “We are excited that these two patients have continued to progress beyond the period of early improvement. Three of the five patients with an AIS conversion in INSPIRE have demonstrated motor recovery and are now classified as AIS C conversions. Having assessments of motor improvements occurring one or two years post-implantation is uncommon and may be indicative of prolonged neural repair.”

About the ISNCSCI Exam

The International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) exam is a full neurological exam designed to characterize a patient’s SCI, including full motor and sensory testing. Based upon the findings of the ISNCSCI exam, an American Spinal Injury Association Impairment Scale (“AIS”) grade classification is determined.

About the Neuro-Spinal Scaffold™ Implant

Following acute spinal cord injury, surgical implantation of the biodegradable Neuro-Spinal Scaffold within the decompressed and debrided injury epicenter is intended to support appositional healing, thereby reducing post-traumatic cavity formation, sparing white matter, and allowing neural repair within and around the healed wound epicenter. The Neuro-Spinal Scaffold, an investigational device, has received a Humanitarian Use Device (HUD) designation and currently is being evaluated in the INSPIRE pivotal probable benefit study for the treatment of patients with acute, complete (AIS A), thoracic traumatic spinal cord injury and a pilot study for acute, complete (AIS A), cervical (C5-T1) traumatic spinal cord injury.
