Treatment of Symptomatic Lumbar Internal Disc Disruption (IDD) With the Biostat® System

Stopped early · Phase 3

Conditions studied: Back Pain, Chronic Low Back Pain, Internal Disc Disruption, Degenerative Disc Disease

In brief

The purpose of this investigation is to establish the safety and efficacy of the Biostat System when used for treatment of chronic low back (lumbar) pain due to symptomatic internal disc disruptions (IDD) by comparing safety and efficacy outcome measures between one group receiving BIOSTAT BIOLOGX® Fibrin Sealant through the Biostat® Delivery Device and another group receiving a preservative-free normal saline control delivered with the Biostat Delivery Device.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age 18 or older and skeletally mature.
• Voluntarily signs the subject informed consent form and agrees to the release of medical information for purposes of this study (HIPAA authorization).
• Physically and mentally able to comply with the protocol, including ability to read and complete required forms, and willing and able to adhere to the follow-up requirements of the protocol.
• Chronic low back pain for at least 6 months.
• Pretreatment baseline low back pain of at least 40 mm on a 100 mm visual analog scale.
• Pretreatment baseline Roland-Morris Disability Questionnaire score of at least 9 on the 24-point questionnaire.
• Leg pain, if present, is of nonradicular origin, i.e., not due to stimulation of nerve roots or dorsal root ganglion of a spinal nerve by compressive forces.
• Leg pain, if present, does not extend below the knee and is no greater than 50% of low back pain as measured on a visual analog scale. If bilateral leg pain, the worst leg pain is no greater than 50% of low back pain.
• Low back pain unresponsive to at least 3 months of nonoperative care, which may include bed rest, antiinflammatory and analgesic medications, chiropractic manipulations, acupuncture, massage, physical therapy or home-directed lumbar exercise program.
• Diagnostic medial branch block or facet joint injection between 18 months and 2 weeks prior to the study procedure indicates no facet joint involvement.
• Diagnosis of symptomatic lumbar (L1-L2 - L5-S1) internal disc disruption (IDD), which requires confirmation of discogenic pain at one or two contiguous levels through positive provocation discography performed between 18 months and 2 weeks prior to the study procedure using pressure manometry and identification of an adjacent nonpainful disc. The disc provocation studies must precisely demonstrate concordant pain (<50 psi above opening pressure) and must demonstrate a fissure(s) in the outer one-third of the posterior or lateral anulus.

You may not qualify if…

• Cauda equina syndrome.
• Active malignancy or tumor as source of symptoms.
• Current infection or prior history of spinal infection (e.g., discitis, septic arthritis, epidural abscess) or an active systemic infection.
• Previous lumbar spine surgery.
• Evidence of prior lumbar vertebral body fracture.
• Disc bulge/protrusion or focal herniation at the symptomatic level(s) > 4 mm.
• Presence of disc extrusion or sequestration.
• Leg pain is greater than 50% of low back pain as measured on a visual analog scale.
• Leg pain that extends below the knee.
• Lumbar intervertebral foramen stenosis at the affected level(s) resulting in significant spinal nerve root compression (effacement of the majority of periganglion fat and loss of CSF signal around the nerve rootlets).
• Symptomatic central vertebral canal stenosis or absolute sagittal vertebral canal diameter < 9mm.
• Loss of disc space height at the symptomatic level(s) greater than one-third of an adjacent normal disc (or of the expected height in the case of an L5-S1 disc).
• Spondylolisthesis (> Grade 1) with or without spondylolysis at the symptomatic level(s).
• Lumbar spondylitis or other undifferentiated spondyloarthropathy.
• Dynamic instability at the symptomatic level(s) on lumbar flexion-extension radiographs indicated by >4.5 mm of translation or angular motion >15° at L1-L2, L2-L3, or L3-L4; >20° at L4-L5; or >25° at L5-S1.
• Diagnostic medial branch block or facet joint injection indicate facet joint involvement.
• Diagnostic sacroiliac injection indicates sacroiliac joint involvement for those patients with pain in the sacral region.
• Sustained relief (>3 months) of low back pain obtained with epidural injection of corticosteroids.
• Symptomatic involvement of more than two lumbar disc levels determined from discography.
• Neurological examination shows findings of radiculopathy or a significant underlying neurological condition (motor strength <4; sensory assessment abnormal; or reflexes absent or hyperactive with clonus).
• Prior thermal intradiscal procedure (e.g., intradiscal electrothermal therapy, intradiscal radiofrequency thermocoagulation).
• Any lumbar intradiscal injection procedure other than discography (e.g., injection of corticosteroids, methylene blue, dextrose, or glucosamine and chondroitin sulfate).
• Significant systemic disease, including unstable angina, autoimmune disease, rheumatoid arthritis, and muscular dystrophy.
• Congenital or acquired coagulopathy or thrombocytopenia; or currently taking anticoagulant, antineoplastic, antiplatelet, or thrombocytopenia-inducing medications; or undergoing radiation therapy.
• History of unexplained, easy, or persistent bruising or bleeding, bleeding from the gums, or bleeding problems experienced in previous surgical procedures.
