InVivo Therapeutics Announces Enrollment of First Two Patients into the INSPIRE 2.0 Study for the Treatment of Acute Spinal Cord Injury

CAMBRIDGE, Mass.–(BUSINESS WIRE)–InVivo Therapeutics Holdings Corp. (NVIV) today announced that
the first two patients have been enrolled into The INSPIRE 2.0
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).

“Having the first two patients enrolled into the INSPIRE 2.0 Study is a
critical milestone for the company and for the spinal cord injury
patient population, as there continues to be inadequate treatment
options for these patients. With eight clinical sites now open for
enrollment, we remain optimistic about continuing to execute on the
INSPIRE 2.0 study and will provide updates when appropriate,” commented
Richard Toselli, M.D., President and Chief Executive Officer of InVivo.

The INSPIRE 2.0 Study is a two-arm 20-patient (10 subjects in each study
arm), randomized, controlled trial designed to provide clinical data
that will supplement the existing clinical results from the company’s
previous single-arm study (INSPIRE 1.0). The definition of study success
for the INSPIRE 2.0 Study is that the difference in the proportion of
subjects who demonstrate an improvement of at least one grade on ASIA
Impairment Scale (AIS) assessment at the six-month primary endpoint
follow-up visit between the Scaffold Arm and the Comparator Arm must be
equal to or greater than 20%.

“We appreciate the investigators’ continued focus and willingness to
support not only this trial, but also this underserved patient
population. Ultimately, we hope to address a large unmet medical need
for spinal cord injury patients,” concluded Dr. Toselli.

INSPIRE 1.0 Study Results

As previously announced by InVivo, 7 of 16 (44 percent) patients who
reached the six-month primary endpoint visit in the INSPIRE 1.0 Study
had an AIS conversion at 6 months, which is the primary endpoint of the
INSPIRE 1.0 Study (defined as improvement in AIS grade from baseline for
all evaluable patients at the six-month visit). Altogether, 19 patients
were implanted with the Neuro-Spinal Scaffold in the INSPIRE
1.0 Study, which is officially closed. Three patients died within two
weeks of implantation, each death deemed unrelated to the Neuro-Spinal
Scaffold or implantation procedure by the respective site’s
Principal Investigators. The Objective Performance Criterion (study
success definition) for the INSPIRE 1.0 Study was a 25 percent AIS
conversion rate based on the published conversion rates for thoracic
spinal cord injury reported in the literature.
