Manuscript details patient outcomes through 24-month follow up visit

InVivo Therapeutics Holdings Corp. (NASDAQ:NVIV) today announced the publication of a peer-reviewed manuscript in Neurosurgery describing the previously disclosed 12- and 24-month data from the Company's single-arm INSPIRE 1.0 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 publication is titled "Acute Implantation of a Bioresorbable Polymer Scaffold in Patients with Complete Thoracic Spinal Cord Injury: 24-Month Follow-up from the INSPIRE Study."

Richard Toselli, M.D., InVivo's President and Chief Executive Officer, said, "In addition to the previous six-month publication covering INSPIRE 1.0 data in the Journal of Neurosurgery: Spine, we are pleased to see the evaluation of patient outcomes through the 24-month follow up visit. We are encouraged that these data support further evaluation of the investigational Neuro-Spinal Scaffold™ and its potential benefit to patients in the ongoing INSPIRE 2.0 Study."

InVivo has officially closed the INSPIRE 1.0 study and recently completed enrollment into a second pivotal clinical study of the investigational Neuro-Spinal Scaffold™ in patients with acute SCI (INSPIRE 2.0). InVivo anticipates presenting topline data from the INSPIRE 2.0 Study in first quarter of 2023. The INSPIRE 2.0 study is a 20-patient (10 subjects in each study arm), randomized, controlled trial that is designed to enhance the existing clinical evidence for the Neuro-Spinal Scaffold™ from the INSPIRE 1.0 study. For more information about the INSPIRE 2.0 clinical trial, please visit ClinicalTrials.gov.
