Comparative Study of Gene-Activated Bone Substitute "Histograft" for Lumbar and Cervical Spinal Fusion

Not Applicable

Recruiting

• Conditions: Cervical Disc Disorder With Radiculopathy; Spinal Stenosis; Lumbar and Other Intervertebral Disc Disorders With Radiculopathy; Biomechanical Lesion, Unspecified

• Registration Number: NCT06365307
• Lead Sponsor: Histograft Co., Ltd.

Brief Summary

The goal of this clinical trial is to evaluate the safety and efficacy of the combination product "Histograft", a bone substitute based on octacalcium phosphate (OCP) and plasmid DNA encoding VEGFA gene, in spinal fusion prosedure in comparison with bone autografts and synthetic material based on β-TCP

Detailed Description

An open-label non-randomized controlled clinical trial will be conducted with two groups of patients. Following enrollment based on specific indication criteria, all patients will undergo surgical treatment (spinal fusion) using either bone substitute "Histograft" (for spinal fusion of cervical and lumbar spine) or bone autograft (for spinal fusion of lumbar spine), or synthetic material based on β-TCP (for spinal fusion of cervical spine). The primary outcomes will involve the bone fusion rate evaluated with computer tomography (CT) at 6 and 12 months. For the safety assessment, the frequency of serious adverse events (SAEs) and adverse events (AEs) will be monitored throughout the entire clinical trial.

Primary Outcome Measures

Name	Time	Method
Adverse events and Severe Adverse Events	Within 1 year after intervention	Frequency of Adverse and Severe Adverse Events after treatment
Spinal fusion	6 and 12 months after intervention	Vertebral fusion: formation of a "bone block" according to CT data (regenerated bone density between the vertebrae without areas of fibrosis and signs of resorption around metal structures)

Secondary Outcome Measures

Name	Time	Method
Unexpected Adverse Drug Reaction	Within 1 year after intervention	Identification of Unexpected Adverse Drug Reaction
SF- 36 score (The Short Form-36)	6 and 12 months after treatment	Assessment of life quality. A score value is ranging from 0 to 100. Higher scores indicate better health status
