VIA Disc NP Pilot for Patients With Symptomatic Degenerated Discs

Study Overview
=================
Brief Summary
-----------------
VIA Disc NP is an allograph intended to supplement the nucleus pulposus tissue in degenerated intervertebral discs.

Detailed Description
-----------------
The study will include adult subjects, ages 18 years or older, with symptomatic lumbar intervertebral disc degeneration that is not adequately resolved by non-surgical standard care. For the purpose of the primary analysis, subjects are considered enrolled in the study once they have signed the informed consent. Each subject will receive one injection per level and be evaluated for efficacy and safety during the 24 month observation period. The study is expected to be completed within 26 months, inclusive of enrollment and follow-up for all subjects. Subjects will be evaluated at baseline and followed through 24 months to establish safety and efficacy of the treatment. The expected duration of subject participation from screening/enrollment through final follow-up is 104 weeks.

Eligibility Criteria
-----------------
Inclusion Criteria: Eligibility for inclusion is evaluated on a site-specific basis based on each subject's medical, clinical, and radiographic presentation. In addition, for study consistency purposes, the MRI imaging will be submitted to Medical Metrics Imaging (MMI), a core lab, for independent review. MMI will review imaging of every subject to confirm radiographic inclusion criteria. The Medical Monitor will make the final determination for inclusion on all subjects based on review of the MRI relevant medical history and source documents.

Exclusion Criteria: Known allergies to components of VIA Disc NP, Gentamicin, or Vancomycin; Contraindications to the proposed sedation/anesthetic protocol; Radicular pain greater than back pain by history or evidence of radicular pain or neurological deficit within the past 6 months. Radicular pain is defined as nerve pain following a dermatomal distribution and that correlates with nerve compression on imaging. Somatic referred pain is allowed; Any of the following conditions at the index level: Contained disc protrusion >5 mm or disc extrusion, or spondylolisthesis >5 mm (lysis and degenerative); Seronegative spondyloarthropathy; Symptomatic spinal stenosis (moderate to severe in degree); Chronic facet syndrome; Spondylodiscitis; Bilateral spondylolysis; Current or history of osteoporotic or tumor-related vertebral body compression fracture; Previous lumbar spine fusion surgery or disc arthroplasty; History of sacroiliac (SI) joint pain/injections during the past 3 months or SI joint fusion within the past two years; Received chemonucleolysis or percutaneous treatment of the affected disc prior to the study; History of epidural steroid injections within 1 week prior to study treatment; Received any lumbar intradiscal treatment injection or procedure (e.g., methylene blue, dextrose, glucosamine, and chondroitin sulfate, or biacuplasty) and any nerve ablation procedures at the same or adjacent level (e.g., Basivertebral nerve ablation, dorsal ramus or sinovertebral nerve ablations). Discography and anaesthetic discography may be performed but must be done at least 2 weeks or more prior to the injection procedure; Been a recipient of prior stem cell/progenitor cell therapy or other biological intervention (e.g., PRP) to repair the target intervertebral disc; Severe motor deficit or cauda equina disorder based on investigator determination; Diagnosis of any traumatic neurological disorders; Severe diseases of any other major body system as judged by the investigator, including malignant diseases of any solid organ or any hematologic malignancy during the previous 5 years; Demonstrate 3 or more Waddell's signs of Inorganic Behavior; Any mental instability, bipolar disorders, post-traumatic stress disorder (PTSD) or uncontrolled anxiety/depression and/or require new or changed anti-depressants or anti-psychotic medications within 3 months of enrollment; Compensated injuries or ongoing litigation regarding back pain/injury, or financial or other incentives to remain impaired; If female and of child-bearing potential, are pregnant or breastfeeding or a plan to become pregnant or breastfeed in the first 12 months post-treatment; Any medical condition that impairs follow-up (i.e., fibromyalgia, rheumatoid arthritis, chronic regional pain syndrome, reflex sympathetic dystrophy); Evidence of substance abuse (including marijuana); Note: subjects using prescribed extended-release narcotics (e.g., fentanyl patch, MS Contin, oxycontin) within the 3 months prior to screening; subjects on long-acting opioids may be given option to wean off opiates before enrollment. Subjects on short-acting opiates (e.g., hydrocodone, oxycodone, tramadol, etc.) may be included and utilization monitored after the treatment; Are currently receiving treatment with radiation, chemotherapy, immunosuppression, or chronic steroid therapy (prednisone, or its equivalent, use of up to 5 mg/qd is allowed, as well as inhalation steroids for asthma); Active implantable devices, such as cardiac pacemakers, spinal cord stimulators, intrathecal pumps, etc.; Bilateral spondylolysis at any level; Fracture of the spine, previous lumbar spine surgery or previous treatment of the target disc.

| --- | --- | --- |
| Patient self-reporting of Functional Efficacy with no change in neurological status using the Oswestry Disability Index (ODI) | Evaluate the change from baseline in functional disability on the Oswestry Disability Index (ODI) measured from 0 (minimal disability) to 100 (maximal disability). The ODI is 10 categories of function to quantify disability due to low back pain. | baseline to 3 months |

Functional responder analysis at 3 and 6 months measured as subjects meeting functional improvement of ≥ 10, 15 and 20 points in ODI scores. | 3-6 months | 
| Patient self-reporting of Pain | Changes in Numeric Rating Scale (NRS) scores. Eleven point pain scale used for patient self-reporting of back pain, which ranges from 0 (no pain) to 10 (the worst pain imaginable). Analysis at 3 and 6 months measured as subjects meeting lower back pain NRS improvement of 50%. | 3-6 months | 
| Patient self-reporting of Pain in low back | Changes in Numeric Rating Scale (NRS) scores.

Analysis at 3 and 6 months measured as subjects meeting lower back pain NRS improvement of ≥30%. | 3-6 months | 
| Oswestry Disability Index (ODI) score change | Change from baseline in ODI scores at 6 months. Ten category index comprising of function to quantify due to low back pain. ODI is measured 0 (minimal disability) to 100 (maximal disability). | baseline and 6 months | 
| Numeric Rating Scale change | Changes from baseline in Numeric Rating Scale (NRS) score at 3 and 6 months. Eleven-point pain scale used for patient self-reporting of pain, which ranges from 0 (no pain) to 10 (the worst pain imaginable). | baseline, 3 and 6 months | 
| Neurological status change | Change from baseline in motor function (graded 0 - no movement to 4 - active movement against resistance), reflexes (0 - absence to 4 - abnormal/hyperactive) and sensory status (graded normal or abnormal) based on physician's physical exam at 1, 3, and 6 months. | baseline to 6 months | 
| Return to work | Patient reported return to work - same or different capacity responses to employment questions will be assessed across time points and compared. | baseline - 6 months | 
| Magnetic Resonance Imaging (MRI) review to determine disc health changes | Magnetic Resonance Imaging (MRI) taken at baseline compared to 6 months reviewing changes in treated disc levels (disc height, volume hydration of disc and Modified Pfirrman grade) | baseline-6 months |
