Clinical Trial Summary

VIA Disc NP is an allograft intended to supplement the nucleus pulposus tissue in degenerated intervertebral discs.

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 (max of 2 levels) and be evaluated for efficacy and safety during the up to 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 up to 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

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.

14. 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;

15. Compensated injuries or ongoing litigation regarding back pain/injury, or financial or other incentives to remain impaired;

16. 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;

17. Any medical condition that impairs follow-up (i.e., fibromyalgia, rheumatoid arthritis, chronic regional pain syndrome, reflex sympathetic dystrophy);

18. 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;

19. 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);

20. Active implantable devices, such as cardiac pacemakers, spinal cord stimulators, intrathecal pumps, etc.

21. Bilateral spondylolysis at any level;

22. Fracture of the spine, previous lumbar spine surgery or previous treatment of the target disc.

The ODI is 10 categories of function to quantify disability due to low back pain.	baseline to 3 months
