InVivo Therapeutics Announces Presentation of Twelve-Month Results from the INSPIRE Study of the Investigational Neuro-Spinal Scaffold™ in Acute Thoracic Complete Spinal Cord Injury

– E-poster Presented at the 2019 American Association of Neurological Surgeons (AANS) Annual Scientific Meeting –

CAMBRIDGE, Mass. (April 17, 2019) – InVivo Therapeutics Holdings Corp. (Nasdaq: NVIV) (“InVivo” or the “Company”) today announced the presentation of the twelve-month results from the company’s single-arm 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). The findings were presented at the 2019 AANS Meeting in San Diego, CA through an e-poster titled, “Twelve Month Results from the INSPIRE Study of the Investigational Neuro-Spinal Scaffold™ in Acute Thoracic Complete Spinal Cord Injury”, co-authored by Kee Kim, M.D., Department of Neurosurgery, UC-Davis, Sacramento, CA, K. Stuart Lee, M.D., Division of Neurosurgery, Vidant Health, Greenville, NC, Lee, Domagoj Coric, M.D., Carolina Neurosurgery and Spine, Charlotte, NC, Nicholas Theodore M.D., Department of Neurosurgery, Johns Hopkins Hospital, Baltimore, MD, and Richard Toselli, M.D.,  President and Chief Executive Officer of InVivo.

As previously announced by InVivo, 7 of 16 (44%) patients who reached the six-month primary endpoint visit in the INSPIRE study had an ASIA Impairment Scale (AIS) conversion at 6 months, which is the primary endpoint of the trial (defined as improvement in AIS grade from baseline for all evaluable patients at the six-month visit). Of the seven patients who reached the six-month primary endpoint visit, six patients were later evaluated at the 12-month exam and one patient was lost to follow-up before the 12-month exam. All six patients who were examined at the 12-month exam and had previously converted at the six-month exam remained converted at the 12-month exam.  Further, two of those six patients were assessed to have AIS B spinal cord injury (SCI) at the six-month primary endpoint but were later assessed to have improved to AIS C SCI at the 12-month visit. The Objective Performance Criterion (OPC) (study success definition) for the study was a 25% AIS conversion rate based on the published conversion rates for thoracic SCI reported in the literature.

Dr. Toselli commented, “In addition to focusing on enrollment in the INSPIRE 2.0 Study, we look forward to continuing to follow this cohort of INSPIRE patients through their 24-month follow up visit, and we remain encouraged by the continued stability of the AIS conversion rates.”
