New device aims to improve spinal fusion for back pain sufferers
NCT ID NCT06462729
First seen Jun 25, 2026 · Last updated Aug 27, 2026 · Updated 3 times
Summary
This study tests a new device called LDGraft, which contains a protein that helps bone grow, for people with degenerative disc disease needing spinal fusion. Forty adults aged 22 to 80 will be randomly assigned to receive either LDGraft or standard bone graft during surgery. The goal is to see if LDGraft is safe and helps bones fuse better than the usual treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- LDGraft (a device containing rhBMP-2, a bone-growth protein)
- What this could lead to
- If it works, this could lead to a new option for spinal fusion that may improve bone healing and reduce the need for additional surgeries.
- What could go wrong
- This is a very early (Phase 1/2) trial with only 40 people, so results may not apply to everyone. Risks include device-related side effects or no better outcome than the current standard.

Inclusion Criteria: 1. Skeletally mature adults ≥22 and ≤80 years at the time of surgery 2. Willing and able to give written informed consent and comply with study protocol and postoperative management program 3. Degenerative disc disease of the lumbosacral spine in one level (L3 to S1) requiring fusion confirmed by patient history and radiographic imaging (CT/MRI/X-rays) with one or more of the following: * instability (as defined by ≥3mm translation or ≥5° angulation); * osteophyte formation of facet joints or vertebral endplates; * decreased disc height, on average by \>2mm, but dependent upon the spinal level; * scarring/thickening of ligamentum flavum, annulus fibrosis, or facet joint capsule; * herniated nucleus pulposus; * facet joint degeneration/changes; and/or * vacuum phenomenon. 4. Preoperative Oswestry Disability Index score ≥ 35 5. Participant has not responded to conservative treatment (e.g. medications, injections, physical therapy, etc.) for a period of 6 months 6. Participant is indicated for an ALIF approach to the lumbar spine Exclusion Criteria: 1. Previous lumbar spine instrumentation (i.e., anterior disc replacement, interspinous device) or a previous interbody fusion procedure in the lumbar spine 2. More than one level lumbar spine level requiring fusion 3. Three or more contiguous lumbar spine levels requiring decompression (Note: Up to two contiguous levels of decompression is acceptable) 4. 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. 5. Pregnant, planning to become pregnant during the follow-up time period, or breast-feeding women 6. Presence of active malignancy 7. Requires bone growth stimulation in the lumbar spine 8. Active local or systemic infection 9. Spondylolisthesis greater than Grade 1 (25% translation) 10. Currently smoking or using nicotine products, including e-cigarette products (e.g., vaping) (Use within 30 days of screening date is considered 'current') 11. Any degenerative muscular or neurological condition that would interfere with evaluation of outcomes, including but not limited to Parkinson's disease, amyotrophic lateral sclerosis (ALS), or multiple sclerosis 12. Any medical condition requiring treatment with any drug known to potentially interfere with bone/soft tissue healing (e.g. chronic systemic steroids) or receiving radiation therapy that is expected to continue for the duration of the study 13. Body Mass Index \> 35 14. Insulin-dependent diabetes mellitus 15. Osteopenia or osteoporosis of the spine, DEXA T score of ≤ -1.0 16. Any secondary causes of osteoporosis (e.g. chronic liver or kidney disease, uncontrolled hyper- or hypothyroidism, type I or type II diabetes mellitus, gastrointestinal malabsorption syndromes) or other conditions known to adversely affect osteogenesis (e.g. Paget's disease, Ehlers-Danlos syndrome or osteogenesis imperfecta) 17. Participation in another investigational study within 30 days prior to surgery for investigational devices, or within the last three months for investigational drugs; 18. Current or recent history of chemical/alcohol abuse or dependency using standard medical definition of DSM-5 (Diagnostic and Statistical Manual) code 19. 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 20. Radiographically compromised vertebral bodies at the index level due to current or past trauma, e.g., by the radiographic appearance of the fracture callus, deformity, malunion or nonunion 21. Currently a prisoner 22. Involved in active litigation relating to his/her spinal condition or workers compensation claimants.
