Registered date:05/10/2021
Investigator-initiated Clinical Trial to Evaluate the Safety and Efficacy of Magnetic targeting using Autologous Bone Marrow-derived Mesenchymal Stem Cell (m-MSC) in Knee Osteoarthritis
Basic Information
Recruitment status | Complete |
---|---|
Health condition(s) or Problem(s) studied | Knee Osteoarthritis |
Date of first enrollment | 20/10/2021 |
Target sample size | 5 |
Countries of recruitment | |
Study type | Interventional |
Intervention(s) | After the arthroscopic bone marrow stimulation technique is performed on the articular cartilage defect, a suspension of bone marrow derived m-MSCs from the subject is injected in the presence of a magnetic field. The magnetic field is maintained for 10 minutes after cell transplantation. |
Outcome(s)
Primary Outcome | 1) Incidence rate of adverse events (%) and incidence rate of defects (%) 2) Confirmation of the occurrence of significant adverse events (neoplastic lesions, allergic symptoms, and unknown infections for which a causal relationship cannot be denied as risks specific to regenerative medical products) |
---|---|
Secondary Outcome | 1) IKDC subjective score 2) Knee Injury and Osteoarthritis Outcome Score (KOOS) 3) Plain X-ray (Kellgren-Lawrence grading) 4) Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score: MRI evaluation 5) International Cartilage Repair Society (ICRS) score: Arthroscopic evaluation (for patients who have consented to arthroscopy) 6) Histological evaluation (for patients who have consented to biopsy) |
Key inclusion & exclusion criteria
Age minimum | >= 20age old |
