Summary
Study to show the safety and tolerability of Intradiscal rhGDF-5 in subjects with early lumbar disc degeneration
Eligibility Criteria
Inclusion Criteria
- Persistent low back pain with at least 3 months of non-surgical therapy at one suspected symptomatic lumbar level (L3/L4 to L5/S1) as confirmed using a standardized provocative discography protocol. The required discography protocol will be provided by the sponsor. Subjects with multilevel disease must have a provocative discogram confirming that only 1 level is symptomatic at least 2 weeks prior to administration. Historical provocative discograms may be used for screening purposes, with an expiry of 12 calendar months from the date performed. If the study treatment is not performed within those 12 calendar months, a new discogram will be required.
- Oswestry Disability Index (ODI) for low back pain of 30 or greater
- Low Back Pain score greater than or equal to 4 cm as measured by Visual Analog Scale (VAS) at Visit 1 Baseline
Exclusion Criteria
- Persons unable to have a discogram, CT, or MRI
- Abnormal neurological exam at baseline (e.g., chronic radiculopathy)
- Active radicular pain due to anatomical compression such as stenosis or disc herniation (radicular pain is defined as pain below the knee)
- Extravasation of contrast agent during the discogram, into the epidural space (does not include leakage of contrast agent along the needle track or leakage to the outer annular ring at the posterior longitudinal ligament vicinity)
- Suspected symptomatic facet joints and/or severe facet joint degeneration at the index level or adjacent segments
