Clinical Trial Summary

The MAST-GR study is a randomized controlled interventional trial with parallel treatment arms and 1:1 allocation

The primary objective of the study is to compare the safety and efficacy of a single intra-articular infiltration of Bone marrow aspirate concentrate (BMAC) with one of minimally manipulated adipose tissue (MM-AT) so as to determine the most effective cellular product in treating patients with knee osteoarthritis (OA).

The secondary objective is to demonstrate whether intra-articular infiltration of BMAC or MM-AT can induce disease-modifying effects in knee OA by imaging and biological assessments on peripheral blood.

The tertiary objective of the study is to identify factors that influence the clinical response to treatment (baseline characteristics of patients, biological characteristics of the treated knee, characteristics of cellular products, BMAC and MM-AT).

Description:

Patients with symptomatic unilateral knee OA will be included in a randomized controlled Trial (RCT), in which one group of patients will be treated with 1 intra-articular infiltration of BMAC, and one group will be treated with 1 intra-articular infiltration of MM-AT. A total of 204 patients will be included and will undergo infiltrative treatment after collecting informed consent for study participation and master data. Patients will be clinically evaluated at 0-2-6-12 months follow-up. Possible disease-modifying effects of the two cell products will be investigated by analysis on peripheral blood at 0-2-6-12 months follow-up and by evaluation of radiographic and magnetic resonance imaging (MRI) at 0 and 12 months follow-up. In addition, characterization of the portion of BMAC and MM-AT remaining from treatment will be carried out, as well as baseline assessment of peripheral blood on all patients, and synovial fluid and synovial membrane, where possible, to analyze their influence on clinical outcome.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Western Ontario and McMaster University Osteoarthritis index (WOMAC) - Pain subscale	It is a pathology-specific questionnaire used for the assessment of referred pain at the knee joint level in patients with OA	6 months follow-up
Secondary	Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)	It's a standardized and widely used questionnaire to assess the condition of patients with osteoarthritis of the knee and includes assessment of pain, stiffness, and physical function of the joints. It can be administered to the patient.; It measures 5 items for pain (range 0-20), two for stiffness (range 0-8), and 17 for functional limitation (range 0-68) that mainly relate to activities of daily living (e.g., getting up from a sitting position, bending over, going up and down stairs etc.); The score is then normalized on a 0-100 scale. Higher values indicate a worse outcome	baseline, 2 months, 6 months, 12 months follow-up
Secondary	Knee Injury and Osteoarthritis Outcome Score (KOOS)	This is a subjective, knee-specific rating scale that is considered one of the most reliable assessment tools in the evaluation of knee pathology. The questionnaire examines the following categories: symptoms, stiffness, pain, daily activities, sports and quality of life	baseline, 2 months, 6 months, 12 months follow-up
Secondary	Visual Analogue Scale (VAS)	Visual analog scale consisting of a straight line segment (10 cm length), the ends of which correspond to "no pain" (0) and "the strongest pain imaginable" (10).	baseline, 2 months, 6 months, 12 months follow-up
Secondary	EuroQol Visual Analogue Scale (EQ-VAS)	EQ-VAS is a visual analog scale that has a range of scores from 0 (worst imaginable health condition) to 100 (best imaginable health condition).	baseline, 2 months, 6 months, 12 months follow-up
Secondary	Tegner Activity Level Scale	Tegner Activity Level Scale is a questionnaire to find out the patient's level of physical activity.All patients will indicate the type of sporting activity performed and its frequency.	baseline, 2 months, 6 months, 12 months follow-up
Secondary	Objective parameters- Range of Motion	Evaluation of the Range of Motion for comparative analysis.	baseline, 2 months, 6 months, 12 months follow-up
Secondary	Objective parameters - Circumferences	Bilateral trans- and supra- patellar circumferences measurement for comparative analysis	baseline, 2 months, 6 months, 12 months follow-up

Patients can express if their state of health will be satisfying, answering "yes" or "no.	baseline, 2 months, 6 months, 12 months follow-up
Secondary	Minimally Clinical Important Difference (MCID)	The patient should indicate the degree of perceived improvement after the infiltrative procedure.	baseline, 2 months, 6 months, 12 months follow-up
Secondary	Expectations about the effectiveness of the treatment	The patient should indicate at baseline what clinical benefits he or she expects from the treatment according to the question, "What benefits do you expect to get as a result of the treatment you will undergo?" the patient can choose from one of the following items:Full recovery, Definitely better, Much better, Slightly better,No change	baseline
Secondary	Kellgren-Lawrence score	The Kellgren Lawrence scale classifies knee OA into 4 grades of subsequent greater severity, the parameters used being reduced joint space and the presence of osteophytes	baseline, 12 months follow-up
Secondary	3 Tesla Nuclear Magnetic Resonance Imaging (3T MRI)	Sequences such as T2-weighted FSE, FS-3D SPGR, and T2 Mapping will be used to assess cartilage thickness and signal, the presence of cysts and subchondral edema, joint profile, the presence of osteophytes and their size, the status of the menisci, both medial and lateral, and the status of the synovium.	baseline, 12 months follow-up
Secondary	Analysis of circulating micro RNAs	miRNAs, involved in OA progression, will be identified and quantified, including miR675-5p, miR-31-5p and miR-33a-5p	baseline, 2 months, 6 months, 12 months follow-up
