NCT06078059

Brief Summary

The goal of this clinical trial is to pharmacologically evaluate the effects of culturued allogeneic umbilical cord blood-derived mesenchymal stromal stem cell (UCB-MSCs) in the treatment of end-stage knee osteoarthritis (Kellgren-Lawrence grade 4) with the analysis of soluble biomarkers and expression of key genes, as well as the evaluation of clinical outcomes with patient-reported outcome measures (PROMs) and recording of potential complications. Patients will be randomized in the intervention and control groups. In both groups, the knee aspiration will be performed 4-6 weeks prior to the knee arthroplasty to analyse baseline synovial fluid characteristics. The intervention group will receive the injection of UCB-MSCs. All patients will complete PROMs questionnaires and maintain a pain diary on visual analogue scale (VAS) at home until the surgery. On the day of admission to hospital for knee arthroplasty, the same questionnaires will be administered again. During the operative procedures, the samples of synovial fluid, synovial membrane and resected cartilage will be obtained and analysed afterwards. It is anticipated that the study results will contribute to elucidate the mechanisms of action of MSCs in the treatment of knee osteoarthritis.

Outcome Measures

Primary Outcomes (3)

  • Soluble biomarkers analysis with multiplex bead-based immunoassays Luminex in synovial fluid

    Luminex assay is a type of immunoassay that precisely measures multiple analytes in one sample. It is a bead-based immunoassay that allows for multiplex detection of analytes simultaneously. Color-coded microspheres or beads are internally dyed with different proportions of red and infrared fluorophores that correspond to a distinct spectral signature or bead region. The quantification of multiple cytokines and other biomarkers in samples provides critical information about biological processes and diseases.

    After sampling

  • Biomarkers analysis with Enzyme-linked immunosorbent assay (ELISA) in synovial fluid

    Enzyme-linked immunosorbent assay (ELISA) is the main approach for the sensitive quantification of protein biomarkers in body fluids and is currently employed in clinical laboratories for the measurement of clinical markers. It also constitutes the main methodological approach for biomarker validation and further qualification.

    After sampling

  • Quantitative real-time PCR (qRT-PCR) analysis of gene expression in chondrocytes and synoviocytes

    Quantitative real-time PCR (qRT-PCR) is a major development of PCR technology that enables reliable detection and measurement of products generated during each cycle of PCR process. The detection of changes in fluorescence intensity during the reaction enables to follow the PCR reaction in real time. qRT-PCR is comprised of several steps: 1. RNA is isolated from target tissue/cells, 2. mRNA is reverse-transcribed to cDNA, 3. modified gene-specific PCR primers are used to amplify a segment of the cDNA of interest, following the reaction in real time, 4. the initial concentration of the selected transcript in a specific tissue or cell type is calculated from the exponential phase of the reaction.

    After sampling

Secondary Outcomes (5)

  • Knee Injury and Osteoarthritis Outcome Score (KOOS)
