PerQdisc Traditional Feasibility Trial.

A Multi-center Traditional Feasibility Trial of the PerQdisc Artificial Implant in Treatment of Single-level Discogenic Back Pain.

This is a traditional feasibility study (TFS) study to evaluate the safety and effectiveness of the PerQdisc. The study is prospective, multicenter, and open label.

After a screening period, qualified participants will be enrolled and treated with the PerQdisc. Patients will not be blinded to their treatment. Participants will then complete the safety follow-up period.

Study Overview

• Status: Recruiting
• Conditions: Discogenic Low Back Pain
• Intervention / Treatment: Device: PerQdisc

Detailed Description

The proposed investigation is a multicenter, prospective, traditional feasibility study of the PerQdisc. A minimum of N=5 subjects will be enrolled. Subjects will be enrolled in approximately 2 sites. Data analyses including all enrolled subjects meeting specific criteria will be submitted to the FDA to support a pivotal trial and used in trial planning. This study will evaluate the safety and effectiveness of the PerQdisc device in the treatment of single level discogenic back pain caused by degenerative disc disease (DDD) (L1 to L5).

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: Adult; Older Adult
• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

1. Skeletally mature male or female subjects aged 22-70 (inclusive).
2. Subject has a primary diagnosis of single level discogenic back pain caused by degenerative disc disease (L1 to L5) identified via MRI.
3. Subject has an intact annulus (as determined by MRI) and endplates (as determined by MRI and X-ray) at the level to be treated.
4. Subject must have failed to respond to a minimum of 6 months of conservative treatment for their back pain (e.g., physical therapy, medications, injections, ablations, lifestyle changes, etc.).
5. Subject has a low back pain VAS ≥40 mm (4 cm).
6. Subject has adequate disc height (≥6mm measured at the center of the disc) at the level to be treated. [As measured by the investigator]
7. Subject is psychosocially, mentally and physically able and willing to fully comply with this protocol including adhering to follow-up schedule and requirements and filling out forms.
8. Subject has read and understands the IRB approved informed consent document prior to signing and dating the document and before the initiation of any study-related procedures
9. Subject is appropriate candidate for the PerQdisc surgical approach [as defined in the surgical technique guide].

Exclusion Criteria:

1. Subject has symptomatic degenerative disc disease at more than one lumbar level
2. Subject has had a prior spinal fusion in the lumbar or thoracic intervertebral spaces.
3. Subject has had a prior SI-joint fusion.
4. Subject has a spinal cord stimulator.
5. Subject has had any prior lumbar spine surgery (instrumented or non-instrumented)
6. Subject has a significant disc herniation at the level to be treated. Significant is defined as a large, extruded herniation that creates a risk for expulsion.
7. Subject has congenital moderate or severe spinal stenosis or epidural lipomatosis.
8. Subject has spondylolisthesis (antero- or retrolisthesis) in static X-ray ≥3 mm [measured via neutral lateral x-ray]
9. Subject has ≥4 mm dynamic spondylolisthesis [measured via flexion/extension x-rays]
10. Subject has > 20 degree range of motion at the index level [measured via flexion/extension x-rays]
11. Subject has a history of any invasive malignancy (except non-melanoma skin cancer) unless treated with curative intent and there have been no clinical signs or symptoms of malignancy for at least 5 years (in particular, spinal tumors).
12. Subject has an active systemic infection or infection at the operative site.

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: PerQdisc; The PerQdisc device is the first in a new category of contained in-situ filled and then cured lumbar spinal implant. The PerQdisc is intended to replace the nucleus pulposus in a single lumbar disc level, preserve motion and alleviate pain. The PerQdisc is a silicone membrane (barrier membrane) configured to be filled with a room temperature vulcanizing silicone (RTVS) that will cure within minutes, resulting in a final shape that conforms to the nucleus space created by the surgical removal of the diseased or damaged nucleus pulposus.

Device: PerQdisc; PerQdisc Artificial Implant
