Intradiscal rhGDF-5 Phase I/II Clinical Trial
Degenerative Disc Disease
About this trial
This is an interventional treatment trial for Degenerative Disc Disease
Eligibility Criteria
Inclusion Criteria:
- Persistent low back pain, with at least 3 months of non-surgical therapy, at one symptomatic lumbar level (L3/L4 to L5/S1) as confirmed using a standardized discography protocol
- Oswestry Disability Index of 30 or greater
- Low back pain score greater than or equal to 4 cm as measured by VAS, at Visit 1 baseline and on day of treatment to confirm eligibility prior to administration
Exclusion Criteria:
- Persons unable to have a discogram, CT or an MRI
- Abnormal neurological exam at baseline (e.g., radiculopathy)
- Radicular pain
- Leak of contrast agent during the discogram, into the epidural space (does not include leak of contrast agent along the needle track)
- MRI findings demonstrate any of the following:· Suspected disc appears normal· >50% decrease in disc height· Modic changes, and/or· Presence of osteophytes or significant facet arthrosis

Experimental
Intradiscal rhGDF-5
The API is recombinant human growth and differentiation factor-5 (rhGDF-5), a recombinant version of human GDF-5. GDF-5 is a member of the transforming growth factor-b (TGF-b) superfamily and the bone morphogenetic protein (BMP) subfamily, and is known to influence the growth and differentiation of various tissues, including the intervertebral disc. In vitro experiments have shown that rhGDF-5 can stimulate gene expression and synthesis of the extracellular matrix proteins type II collagen and aggrecan. In vivo experiments in rabbit models of disc degeneration have shown that intradiscal injections of rhGDF-5 can stimulate an increase in disc height and hydration.
