The INSPIRE Study: InVivo Study of Probable Benefit of the Neuro-Spinal Scaffold(TM) for Safety and Neurologic Recovery in Subjects With Complete Thoracic AIS A Spinal Cord Injury
Description
Brief Summary
This is an HDE probable benefit, open-label, non- randomized, single-arm, multicenter study
to evaluate the safety and probable benefit of the poly(lactic-co-glycolic
acid)-b-poly(L-lysine) Scaffold ("Scaffold") in subjects with thoracic AIS A traumatic spinal
cord injury at neurological level of injury of T2-T12.
Detailed Description
This is an HDE probable benefit, open-label, non-randomized, single-arm, multicenter study to
evaluate the safety and probable benefit of the poly(lactic-co-glycolic
acid)-b-poly(L-lysine) Scaffold ("Scaffold") in subjects with thoracic AIS A traumatic spinal
cord injury at neurological level of injury of T2-T12.
The study will be conducted by qualified Investigators who have been trained on the surgical
Scaffold implant procedure in order to enroll subjects in the Primary Endpoint Analysis Set,
defined as all subjects with a successful Scaffold implant, no major protocol deviations, and
a complete 6-month Primary Endpoint Follow-up Visit. After receiving the Scaffold and
following discharge, subjects will participate in a comprehensive rehabilitation program. For
the first 24-months after implantation of the Scaffold, Follow-up and Long-term Follow-up
assessments will be conducted at either the study site or the rehabilitation center. The
Long-term Follow-up annual visits for years 3 through 10 will be conducted over the
telephone.
Phase
N/AInclusion and Exclusion Criteria
- Subjects must meet all of the following to be considered eligible:
- AIS A classification of traumatic spinal cord injury at T2-T12 neurological level of injury confirmed by a qualified medical professional
- Recent injury (must receive Scaffold within 7 days from injury)
- Non-penetrating SCI (contusion injury) that is no less than approximately 4 mm in diameter by MRI
- Requires open spine surgery allowing access to the injured spinal cord (subjects requiring either posterior surgical approach or posterior plus anterior approach will be eligible)
- Informed consent obtained
- 16-70 years of age, inclusive
- Hemodynamically stable and deemed a suitable candidate for surgery
- Subjects who meet any of the following will be excluded:
- Terminally ill subjects not likely to be able to participate in follow-up
- Incomplete spinal cord injury (AIS B, C, D, and E injuries)
- Subjects with more than one discrete spinal cord injury (contusion) will be excluded.
- No discrete cavity (existing or created by irrigation/myelotomy) in the contused spinal cord in which a Scaffold can be placed
- Evidence of clear and significant Somatosensory Evoked Potentials (SSEP) transmission through the injury site before Scaffold implantation (based on the judgment of the Investigator)
- Subjects with clinically significant pre-existing neurological comorbidities that are unrelated to the contusion being treated (e.g., multiple sclerosis, amyotrophic lateral sclerosis, significant prior peripheral nerve dysfunction, residual problems related to previous spine-related neurological pathologies) will be excluded only if it is felt that these preexisting morbidities will increase risk, affect safety monitoring, or confound study results
- Spinal cord injury associated with significant traumatic brain injury or coma that, in the opinion of the Investigator, would preclude adequate assessment of spinal cord function, brain injury that could be associated on its own with sensory or motor deficits, or subjects with any other reason that results in an unreliable International Standards of Neurological Classification of Spinal Cord Injury (ISNCSCI) exam
- Subjects with clinically significant pre-existing respiratory disease not related to the contusion being treated (e.g., chronic obstructive pulmonary disorder)
- Subjects requiring Long-term ongoing mechanical ventilation
- Subjects with documented immune deficiency disorders, including a known diagnosis of HIV infection/AIDS
- Recent (according to Diagnostic and Statistical Manual of Mental Disorders (DSM) IV or DSM V criteria) history of abuse of narcotics or other significant substance abuse
- Significant injury complications where, in the view of the Investigator, participation in the study could further complicate subject care, limit study follow-up, or confound interpretation of safety or efficacy data.
- A female who is: - Pregnant, or planning to become pregnant within the next 12-months; or - Breastfeeding; or - A woman of child-bearing potential (defined as post menarche and biologically capable of becoming pregnant [i.e., not surgically sterile]) who is engaged in active heterosexual relations and is not willing to use a barrier or hormonal form of birth control for 12-months following Scaffold implantation (e.g., oral, injected, or implanted contraceptives)
- A male who is engaged in active heterosexual relations and is not willing to use birth control for 3-months following Scaffold implantation including sperm donation or banking
- Current or impending incarceration
- Complete spinal cord transection
- Subjects with spinal cord injuries directly due to gunshot, knife, or other penetrating wounds.
- Known hypersensitivity to poly(lactic-co-glycolic acid) (PLGA) or poly-L-lysine (PLL) (e.g., hypersensitivity to absorbable sutures containing PLGA)
- History of severe mental illness (according to DSM IV or V)
- Evidence of pre-trauma active local or systemic infection
- Participation in another interventional clinical trial for six months after Scaffold implantation
- Body mass index (BMI) over 39
- Having a medical condition (e.g., cardiovascular disease, life threatening injuries), or receiving medical treatment, or having any other reason that, in the judgment of the Investigator, precludes successful participation and follow-up for at least six months or confounds collection or interpretation of study safety, feasibility, or efficacy data
