Eligibility Criteria:
Inclusion Criteria:
1. Written informed consent by the patient.
2. Male or female patient ≥ 25 up to and including 75 years old. Females of childbearing potential with a negative urine pregnancy test at Screening. Females of childbearing potential must agree to use acceptable contraception for at least 12 months after surgery and investigational product placement.
3. Patients with degenerative disc disease with up to grade 1 spondylolisthesis and with leg pain requiring up to 3 levels of laminectomy/decompression and a single-level fusion (L2 - S1). DDD is defined by the presence of one or more of the following:
1. instability (angulation ≥ 5 degrees or translation ≥ 3 mm on flexion/extension radiographs),
2. osteophyte formation of facet joints or vertebral endplates,
3. decreased disc height by \> 2 mm, but dependent upon the spinal level,
4. scarring/thickening of ligamentum flavum, annulus fibrosis or facet joint capsule,
5. disc degeneration and/or herniation,
6. facet degeneration,
7. vacuum phenomenon.
4. Patients with an Oswestry Disability Index (ODI) score ≥ 35.
5. Patients with a Visual Analogue Scale (VAS) leg score ≥ 40.
6. Failed conservative treatment (physical therapy, bed rest, medications, spinal injections or transcutaneous electrical nerve stimulation) for a period of 6 months prior to study enrollment.
7. Patients willing to undergo PK sampling.
Exclusion Criteria:
1. Patients with open epiphyseal plates.
2. Patient requiring emergency spinal decompression or spinal fusion.
3. Patients requiring multilevel fusion or expected to need secondary intervention within one year following surgery.
4. Any prior fusion or attempted fusion at an adjacent level.
5. Any prior fusion or attempted fusion at the index level.
6. Pregnant or breast-feeding women.
7. Known or suspected allergies to any of the components of KUR-113 Bone Graft (e.g.
hypersensitivity to aprotinin).
8. Any prior use of teriparatide or abaloparatide or graft material containing PTH1-34.
9. Patients with hypercalcemic disorders (e.g., primary hyperparathyroidism).
10. Patients with Paget's Disease or unexplained high levels of alkaline phosphatase.
11. Prior radiation therapy involving bone.
12. Medical history or radiographic evidence of a metabolic bone disorder (e.g. Paget's Disease) or other condition that would negatively impact the healing process.
13. Any medical condition requiring radiotherapy or immunosuppression.
14. History of thyroid autoimmune disease (Hashimoto's thyroiditis, Graves' disease) or hyperthyroidism.
15. Patients on chronic systemic steroids (i.e. \> 14 consecutive days) within 6 months prior to Screening Visit.
16. Osteopenia (T score \< -1.0) or osteoporosis of the spine (T score \< -2.5).
17. DDD related to benign or malignant tumor.
18. History or presence of active malignancy.
19. Hereditary disorders predisposing to osteosarcoma.
20. Patients with invasive skin cancer.
21. Evidence of local or systemic infection.
22. Patients with known active COVID-19 disease.
23. Current smokers.
24. Type 1 diabetes (regardless of HbA1c) or Type 2 diabetes with a documented HbA1c \> 7.0.
25. Any acute or chronic concurrent medical conditions that in the Investigator's opinion are a contraindication to the procedure and study participation.
26. Participation in another investigational study within 30 days prior to surgery for investigational devices, or within the last three months for investigational drugs. (Note: trials requiring extended follow-up for products that were investigational, but have since become commercially available, are not considered investigational trials).
27. Known substance abuse, psychiatric disorder or a condition which, in the opinion of the investigator, may influence the healing or ability to comply with protocol requirements.
28. Involved in active litigation relating to his/her spinal condition or workers compensation claimants.
29. BMI greater than 40.
