Group Intervention Description Autologous Mesenchymal Stromal Cells (MSC) Autologous MSCs Treatment with 40 millions of autologous autologous adult mesenchymal stem cells from expanded bone marrow administered intra-articularly. Allogenic Mesenchymal Stromal Cells (MSC) Allogenic MSCs Treatment with 40 millions of adult allogeneic expanded bone marrow mesenchymal stem cells administered intra-articularly. Active Control Hyaluronic Acid Hyaluronic Acid 60mg/3ml administered intra-articularly.
- Primary Outcome Measures
Name Time Method Range of motion. 12 months Evaluation of clinical-functional response using Joint range-of-motion evaluation (Flexion score 0º-140º / Extension score -140º-0º / Hyperextension: positive degrees from 0).
Pain self-assessment. 12 months Evaluation of pain using Visual Analogue Scale (VAS) (Pain self-assessment score range from 0 -no pain- to 10 -maximum-).
Radiological response using nuclear magnetic resonance imaging. 12 months Evaluation of radiological response using T2 mapping nuclear magnetic resonance imaging (screening visit global mean of T2 values versus 12 months visit global mean of T2 values).
Knee Osteoarthritis. 12 months Evaluation of Knee Osteoarthritis using Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) \[measures five items for pain (score range from 0 -no pain- to 20 -maximum-), two for stiffness (score range from 0-no stiffness- to 8 -maximum-), and 17 for functional limitation (score range from 0 -no limitation- to 68 -maximum-)\]
Functional response. 12 months Evaluation of functional response using Lequesne Algofunctional Index (score range from 0 to 24). It includes measures of pain (5 questions), walking distance (1 question) and activities of daily living (4 questions) with separate versions for the hip and knee. The scores for each question are summed to obtain a combined score of disease severity. Scores 1 to 4 are classified as mild osteoarthrosis; 5 to 7, moderate; 8 to 10, severe; 11 to 13, very severe; and 14 and above, extremely severe.
X-ray changes of osteoarthritis. 12 months Radiological response using Kellgren and Lawrence classification system (grade from 0 to 4):
* grade 0 (none): definite absence of x-ray changes of osteoarthritis.
* grade 1 (doubtful): doubtful joint space narrowing and possible osteophytic lipping.
* grade 2 (minimal): definite osteophytes and possible joint space narrowing.
* grade 3 (moderate): moderate multiple osteophytes, definite narrowing of joint space and some sclerosis and possible deformity of bone ends.
* grade 4 (severe): large osteophytes, marked narrowing of joint space, severe sclerosis and definite deformity of bone ends.
- Secondary Outcome Measures
Name Time Method Feasibility assessment of a multicentre strategy production of both cell types with several Cell Production Units 24 months Rate of products not conforming to the validation criteria in each arm of experimental treatment.
Evaluate induced changes in circulating cells of the immune system after cell treatment (exploratory objetive) 30 days Evaluation of cell populations (NK cells, B cells, regulatory T cells, myeloid suppressor cells, T cell populations) by flow cytometry, prior to administration of cell therapy, at 7 days and 30 days.
Evaluation of activation and inhibition markers in T lymphocytes (CD69, HLADR, CD137, PD1, LAG3 and TIM3) prior to administration of cell therapy, at 7 days and 30 days Population of inflammatory cytokines circulating in peripheral blood (Plex deB iorad -reference M50DKFADY), prior to administration of treatment, at 7 days and 30 daysPerceived general well-being. 6, 12 and 24 months Evaluation of quality of life using Short Form-12 Health Survey questionnaire (SF12) \[score range from 0 (the worst health status for that dimension) to 100 (the best health status)\]
Evaluation of presence of adverse events related with investigational medical product (IMP). 24 months Rate of adverse events and other pharmacovigilance parameters in the three treatment arms.
Evaluation of products obtained by genomic study and potency studies of the final products of all cell types (exploratory objective) 30 days Studies of the cell product. In this exploratory objective, genomic studies will be carried out using RNA-seq and open array on the advanced therapy drugs manufactured in the study (both autologous and allogeneic), and a correlation will be made with clinical and biological parameters and with the response.
