Not Applicable

Active, not recruiting

• Conditions: Degenerative Disc Disease; Disc Degeneration; Low Back Pain
• Interventions: Other: VIA Disc NP

• Registration Number: NCT05201287
• Lead Sponsor: VIVEX Biologics, Inc.

Brief Summary

VIA Disc NP is an allograft 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 (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.

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.

Group	Intervention	Description
VIA Disc Nucleus Pulposus Allograft	VIA Disc NP	A single dose, intradiscal injection of 100mg of VIA Disc NP mixed with 2ml sterile saline administered to the affected 1 or 2 levels, L1-S1.

Primary Outcome Measures

Name	Time	Method
Patient self-reporting of Functional Efficacy with no change in neurological status using the Oswestry Disability Index (ODI)	baseline to 3 months	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.

Numeric Rating Scale change	baseline, 3 and 6 months	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).
Patient self-reporting of Function	3-6 months	Owestry Disability Index (ODI) is measured 0 (minimal disability) to 100 (maximal disability). This index is comprised of ten categories of function to quantify disability due to low back pain. Functional responder analysis at 3 and 6 months measured as subjects meeting functional improvement of ≥ 10, 15 and 20 points in ODI scores.
Neurological status change	baseline to 6 months	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.
Oswestry Disability Index (ODI) score change	baseline and 6 months	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).
Return to work	baseline - 6 months	Patient reported return to work - same or different capacity responses to employment questions will be assessed across time points and compared.
Magnetic Resonance Imaging (MRI) review to determine disc health changes	baseline-6 months	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, T1rho relaxation, T2 relaxation for up to 10 subjects)
