InVivo Therapeutics Announces Update on the INSPIRE Study and FDA Approval of Expansion of the Study to 20 Evaluable Patients


CAMBRIDGE, Mass. (July 12, 2016) – InVivo Therapeutics Holdings Corp. (NVIV) today provided an update on the INSPIRE study of the Neuro-Spinal Scaffold™.

Patient Enrollments

InVivo announced that the 9th and 10th patients have been implanted with the Neuro-Spinal Scaffold in the INSPIRE study. The 9th patient was implanted at Vidant Medical Center, a Level 1 trauma center located in Greenville, North Carolina. The implantation was performed by Vidant Medical Group neurosurgeons Stuart Lee, M.D., the Principal Investigator at the site, and Hilal Kanaan, M.D., approximately 40 hours after the injury occurred. Dr. Lee said, “The implantation procedure went smoothly and the patient is doing well. We are excited to be a part of the INSPIRE study and look forward to following the patient’s progress.”

The 10th patient was implanted approximately 18 hours after the injury by Domagoj Coric, M.D., of Carolina Neurosurgery and Spine Associates, Chief of Neurosurgery at the Carolinas Medical Center and a member of the INSPIRE Study Steering Committee. Dr. Coric and Dr. William Bockenek, Chief Medical Officer at Carolinas Rehabilitation, are Co-principal Investigators at this site. Regrettably, the 10th patient died from a stroke several days after the implantation procedure. The cause of death was deemed by Dr. Coric and the Chairman of the DSMB to be unrelated to the Neuro-Spinal Scaffold or the implantation procedure.

Mark Perrin, InVivo’s Chief Executive Officer and Chairman, said, “We express our condolences to the family of the patient who passed away. Each loss of an individual with a spinal cord injury strengthens our resolve to develop and bring to market new treatments that will improve the lives of patients with these devastating injuries.”

Expansion of INSPIRE Study

As previously communicated, the INSPIRE study was approved originally to enroll 12 patients pending review of six-month safety data from the first five patients implanted with the Neuro-Spinal Scaffold. In addition to the 10 implanted patients, two patients were screen failures, which means that the patients consented to participate in the study but failed to meet all of the inclusion and exclusion criteria of the study. Although these two screen failure patients were not implanted with the Neuro-Spinal Scaffold, they were technically enrolled into the INSPIRE study. Therefore, the study had enrolled 12 patients by the end of May (when the 10th patient was implanted by Dr. Coric) and the enrollment of additional
patients required action from the FDA.

After reviewing the six-month safety data, the FDA requested minor modifications to the INSPIRE study protocol and informed consent documents. These modifications are being incorporated, and the FDA has approved the enrollment of additional patients to allow for 20 evaluable patients (with six months of follow up data) in the INSPIRE study. Because of the frequent interactions with the FDA over the last several weeks regarding relatively minor modifications, InVivo chose to postpone updates on the INSPIRE study until there was clarity regarding the path forward. “We are pleased that the FDA has approved expansion of the INSPIRE study that clears the way for enrolling all 20 evaluable patients,” Mr.Perrin said. “While the pause in enrollment for the last several weeks was unfortunate, this approval is an important step toward our goal of approaching full enrollment of the INSPIRE study by the end of the year.”

During the interactions regarding the expansion of the INSPIRE study, the FDA also recommended that InVivo include a control arm in the study as part of a Study Design Consideration. Mr. Perrin said, “As is typical of the regulatory process, we have addressed a number of Study Design Considerations regarding the INSPIRE study and its pilot precursor study over the last two years. We have begun a constructive discussion with the FDA regarding this Study Design Consideration, and we will provide an update if substantial changes are made to the study protocol. We continue to believe that our current study design is sufficient to demonstrate safety and probable benefit in support of a Humanitarian Device Exemption (HDE) application for marketing approval. Given the encouraging results that we have observed to date, we look forward to working with the FDA to complete the INSPIRE study as efficiently as possible.”

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 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 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.
