InVivo Therapeutics Reports Conversion of a Fourth Patient Implanted with the Neuro-Spinal Scaffold ™ in the INSPIRE Study

2016-04-26 08:00 ET - News Release

- Four Out of First Six Patients Have Converted from Complete to Incomplete Spinal Cord Injury –

InVivo Therapeutics Holdings Corp. (NVIV) today announced that the sixth-implanted patient in the INSPIRE study has improved from a complete AIS A spinal cord injury to an incomplete AIS B spinal cord injury. This is the fourth out of the first six patients (67%) with at least two months of follow up data to have had an AIS grade improvement.

The Objective Performance Criterion (OPC), a measure of study success for the INSPIRE study, is defined as 25% or more of the patients having improved by at least one AIS grade by six months post-implantation. Several large natural history databases indicate that fewer than 16% of patients with complete thoracic injuries have an AIS grade improvement by six months post-injury. *

“We’re encouraged by the progress the patient has made in the first two months after injury. It’s still early in the patient’s recovery period, and we look forward to monitoring this patient for signs of further neurological recovery,” said Wilson (Zack) Ray, M.D. Dr. Ray performed the implantation at the Barnes-Jewish Hospital at Washington University Medical Center in St. Louis, MO.

“The proportion of patients in the INSPIRE study that have recovered some neurological function is impressive. This most recent conversion brings us closer to achieving the study’s Objective Performance Criterion of five patient conversions. We will be enrolling 13 additional evaluable patients in order to reach 20 patients at six months, and we only need to observe one additional conversion in order to meet the OPC,” said Mark Perrin, InVivo’s Chief Executive Officer and Chairman. “Our goal is to approach full enrollment by the end of this year and file for Humanitarian Device Exemption approval next year.”

All patients enrolled in the INSPIRE study have complete (AIS A) spinal cord injuries at the time of enrollment. In the time between the one-month and the two-month post-injury assessment, the sixth patient treated improved from a complete AIS A spinal cord injury to an incomplete AIS B spinal cord injury. The ASIA Impairment Scale (AIS) is a five grade scale (AIS A-E) that measures the severity of a spinal cord injury.

About The INSPIRE Study

The INSPIRE Study: InVivo Study of Probable Benefit of the Neuro-Spinal Scaffold™ for Safety and Neurologic Recovery in Subjects with Complete Thoracic AIS A Spinal Cord Injury, is designed to demonstrate the safety and probable benefit of the Neuro-Spinal Scaffold™ for the treatment of complete T2-T12/L1 spinal cord injury in support of a Humanitarian Device Exemption (HDE) application for approval. For more information, refer to https://clinicaltrials.gov/ct2/show/study/NCT02138110.

About the Neuro-Spinal Scaffold™ Implant

Following acute spinal cord injury, surgical implantation of the biodegradable Neuro-Spinal Scaffoldwithin the decompressed and debrided injury epicenter is intended to support appositional healing, thereby reducing post-traumatic cavity formation, sparing white matter, and allowing neural regeneration across 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 complete (AIS A) traumatic acute spinal cord injury.
