A Phase I/II Clinical Trial to Evaluate Safety and Efficacy of Autologous Nucleus Pulposus Cells (aNPC) Transplantation in the Treatment of Degenerative Disc Disease
This is an open-label, single-center Phase I/II clinical trial investigating the safety and efficacy of autologous nucleus pulposus cells (aNPC) in patients with disc degeneration. Eligible participants are those assessed by the principal investigator to have disc herniation suitable for discectomy and confirmed disc degeneration. During the treatment period, participants will receive a single injection of autologous nucleus pulposus cells at a concentration of approximately 1×10⁶ viable cells/mL with a total volume not exceeding 3 mL. The injection will be guided by C-arm X-ray to ensure accurate placement into the degenerated central nucleus pulposus of the disc from which tissue was previously harvested. Participants will be followed for 12 months. Safety assessments will primarily include monitoring for inflammatory responses using ESR and CRP after cell injection, as well as recording any treatment-emergent adverse events (AEs). Efficacy will be evaluated using pain assessment and imaging outcomes, including lumbar X-ray and MRI reviewed independently by a radiologist. Additionally, patient-reported outcomes will assess quality of life improvements following treatment using the Visual Analogue Scale (VAS), Activities of Daily Living (ADLs), and the Oswestry Disability Index (ODI). Laboratory tests, including CBC/DC, BUN, creatinine, AST, and ALT, will also be conducted throughout the treatment and observation period to monitor participant safety.
