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

Non-Randomized Controlled Comparative Study of Gene-Activated Osteoplastic Material "Histograft" in Patients With Degenerative Diseases of the Lumbar and Cervical Spine

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

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.

Inclusion Criteria:

• signing the informed consent

Exclusion Criteria:

• refusal to sign IP
• age less than 18 years
• history of spinal surgery in the area of planned spinal fusion
• decompensated forms of chronic diseases
• oncological diseases with identified metastases or risk of metastasis
