Further study details as provided by Baxter Healthcare Corporation:

Primary Outcome Measures:
  • Fusion, defined as evidence of bridging trabecular bone present at 1 year as assessed by CT scan as well as a determination of no motion as assessed by plain radiographs. [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • Improvement clinical outcomes measurements compared to pre-opscores: pain/Disability as measured by Oswestry Lower Back Pain Questionnaire, quality of Life as measured by Short Form Health Survey (SF36), and neurological status [ Time Frame: 1 year ]

Enrollment: 20
Study Start Date: June 2007
Study Completion Date: December 2012
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Has degenerative disc disease of the lumbar spine as indicated by back pain of discogenic/degenerative origin, with or without leg pain, and has one or more of the following conditions as documented by plain X-rays, CT scan or MRI scan:

    • Modic changes.
    • High intensity changes in the annulus.
    • Loss of disc height.
    • Decreased hydration of the disc.
    • Canal stenosis with or without spondylotic slip.
    • Gross facet joint changes requiring fusion for treatment.
    • Have documented annular pathology by other means. (e.g., with discography).
  • Has a preoperative Oswestry Back Disability Score of 30 or more.
  • Aged 18 to 75 years and skeletally mature at time of surgery.
  • Has not responded to non-operative treatment (e.g., bed rest, physical therapy, medications and/or spinal injections) for a period of six months.
  • If of childbearing potential, patient is non-pregnant, non-nursing and agrees not to become pregnant for one year following surgery.
  • Is willing to and able to comply with the study plan and able to understand and sign the Patient Informed Consent Form.

Exclusion Criteria:

  • Has had previous failed attempts at fusion surgery at the involved level(s).
  • Has a diagnosis of spinal infection tumour or trauma.
  • Requires surgery at more than two (2) levels.
  • Has osteoporosis (excluding osteopenia) as evidenced on plain X-rays, CT scans (or DEXA scan in cases of doubt).
  • Is pregnant.
  • Is an alcohol and/or drug abuser as defined by currently undergoing treatment for alcohol and/or drug abuse.
  • Has received drugs that may interfere with bone metabolism within two weeks prior to the planned surgery date (e.g., steroids or methotrexate) excluding routine perioperative, non-steroidal anti-inflammatory drugs.
  • Has a history of autoimmune disease.
  • Has a history of exposure to injectable collagen implants.
  • Has a history of hypersensitivity to protein pharmaceuticals (monoclonal antibodies or gamma globulins) or collagen.
  • Has received treatment with an investigational therapy (device and/or pharmaceutical) within 30 days prior to surgery or such treatment is planned during the 24 months following surgery.
  • Has received any previous exposure to any/all BMPs of either human or animal extraction.
  • Has a history of allergy to bovine products or a history of general anaphylaxis.
  • Has a history of any endocrine or metabolic disorder known to affect osteogenesis (e.g., Paget's disease, renal oseodystrophy, Ehlos-Danlos syndrome or osteogenesis imperfecta).
  • Has any disease that would preclude accurate clinical evaluation (e.g., neuromuscular disease, etc.).
  • Has a primary diagnosis of a spinal disorder other than degenerative disc disease or other conditions as set out in "inclusions" above at the involved level(s).
  • Has a condition that requires postoperative medications that interfere with fusion, such as steroids or prolonged use of non-steroidal anti-inflammatory drugs, excluding routine perioperative non-steroidal anti-inflammatory drugs. This does not include low dose aspirin for prophylactic anticoagulation.
  • Has overt or active bacterial infection, local or systemic, and/or a potential for bacteremia.
  • Has presence of active malignancy or prior history of malignancy (except for basal cell carcinoma of the skin).
  • Has a documented metal allergy or intolerance to titanium alloy or cobalt-chrome-molybdenum alloy.
  • Is, in the opinion of the Principal Investigator or Co-Investigators, intellectually unable to co-operate with the study.
  • Has chronic or acute renal and/or hepatic failure or prior history of renal or hepatic disease.
