- Participant has not responded to conservative treatment (e.g. medications, injections, physical therapy, etc.) for a period of 6 months
Exclusion Criteria:
- Previous lumbar spine instrumentation (i.e., anterior disc replacement, interspinous device) or a previous interbody fusion procedure in the lumbar spine
- More than one level lumbar spine level requiring fusion
- Three or more contiguous lumbar spine levels requiring decompression
- Known hypersensitivity or allergy to any components of the study treatments inclusive of hypersensitivity or allergy to any BMP-2 type recombinant proteins or peptides.

- Body Mass Index > 40
- Insulin-dependent diabetes mellitus
- Osteopenia or osteoporosis of the spine
- Any secondary causes of osteoporosis or other conditions known to adversely affect osteogenesis
- Participation in another investigational study within 30 days prior to surgery for investigational devices, or within the last three months for investigational drugs
- Current or recent history of chemical/alcohol abuse or dependency using standard medical definition of DSM-5 code
- In the opinion of the investigator, the participant has a behavioral, cognitive, social or medical problem that may interfere with the assessment of the safety or effectiveness of the product
