InVivo Therapeutics Announces Publication in Neurosurgery of Lifetime Hospitalization Costs for Thoracic Spinal Cord Injury Patients by Severity Grade


– Costs substantially lower for patients with less severe AIS Grade –

CAMBRIDGE, Mass. (September 5, 2017) – InVivo Therapeutics Holdings Corp. (NVIV) today announced the publication of an article titled “Relationship of American Spinal Injury Association Impairment Scale Grade to Post-injury Hospitalization and Costs in Thoracic Spinal Cord Injury” in the journal Neurosurgery. Neurosurgery is the official journal of the Congress of Neurological Surgeons. The article estimates the lifetime economic costs associated with hospitalizations in relation to American Spinal Injury Association Impairment Scale (AIS) grade. AIS grades are widely-used measures of spinal cord injury (SCI) severity that range from AIS A (complete) to AIS E (normal). The article concludes that patients with less severe thoracic SCI, as reflected in AIS grade, spend fewer days hospitalized over their lifetimes, leading to lower costs of inpatient care. Therefore, therapies improving AIS grade following thoracic SCI may provide cost savings in addition to addressing substantial unmet need.

Specifically, the article reports a lifetime net present value cost savings of about $72,000 for patients with thoracic AIS B SCI as compared to patients with thoracic AIS A SCI, and of about $132,500 for patients with thoracic AIS C SCI as compared to patients with thoracic AIS A SCI.

Dr. Steven Kirshblum, Director of the Spinal Cord Injury Program at the Kessler Institute for Rehabilitation and one of the authors of the article, said “This article is a valuable contribution to the literature regarding the economic burden of spinal cord injury. This is one of the first articles to evaluate a key component of long-term treatment cost by AIS grade and level of injury and establishes that improvement in AIS grade may be associated with cost savings.”

“We are very pleased to have our first publication regarding the financial burden of illness of spinal cord injury and the potential economic impact of patients converting to less severe AIS grade,” Mark Perrin, InVivo’s CEO and Chairman, said. “This publication focuses on the re-hospitalization costs associated with patients with different AIS grades, but there are also many other direct healthcare costs and indirect costs, such as lost wages, associated with SCI. In the future, we plan to continue to evaluate the burden of illness by AIS grade and to publish additional findings. As we work to complete the INSPIRE study of the Neuro-Spinal Scaffold™, we anticipate that these publications will serve as foundational components of our commercial launch strategy.”

The publication is now available electronically through Neurosurgery prior to print publication at: https://doi.org/10.1093/neuros/nyx425.
