Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of this study is to evaluate the pharmacodynamic profile of an oral enzyme treatment with Bromelain, Trypsin and Rutoside in subjects with Osteoarthritis.;Secondary Objective: The secondary objectives are to evaluate: • Vital signs and anthropomorphic measurements; • Knee pain; • Knee function; • Patient global assessment of disease activity (PGADA); • Patient physical activity; • Body metabolism; • Clinical chemistry; • Joint structure modification; • Volume of joint effusion; • Tolerance; • Compliance; • Responder to treatment.;Primary end point(s): The primary endpoints for evaluation of the pharmacodynamic profile are: • Effects on cartilage biomarkers using immunoassays; • Effects on markers of innate immune response; • Effects on systemic inflammatory markers using immunoassays; • Effects on cellular pathways identified by changes in proteomic profile.;Timepoint(s) of evaluation of this end point: At four timepoints for the entire treatment period (cross-over design, 2 parallel arms): During the first treatment period: - at V0 (baseline) - at V2 (8 weeks post-baseline) During the second treatment period: - at V3 (12 weeks post-baseline and including 4 weeks wash out) - at V5 (20 weeks post-baseline) | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): The secondary endpoints are: • Blood Pressure (BP), Heart Rate (HR), Temperature, Weight, Height and BMI; • Knee pain at rest and while walking using a Visual Analogue Scale (VAS); • Global score and each of the five subscales scores of the Knee Injury and Osteoarthritis Outcome Score (KOOS) using a self-administered questionnaire; • PGADA using a VAS; • Global physical activity using a connected device; • Concentration of growth factors in serum (e.g. TGF-ß1_ß2_ß3) using immunoassays; • Clinical chemistry measurements using immunoassays: - Concentration of myokines (e.g. myostatin); - Concentration of hemoglobin, hematocrit, erythrocyte count, Triglyceride (TG), Total cholesterol (TC), LDL, HDL, glucose, hsCRP, uric acid, coagulation markers and key hepatic enzymes; • Semi-quantitative joint assessment of knee OA features using MOAKS (MRI Osteoarthritis Knee Score) or WORMS (Whole-Organ Magnetic Resonance Imaging Score); • Volume of joint effusion by magnetic resonance imaging (MRI); • Adverse Events (AE) and drop out; • Tablet count; • Responder rate to treatment defined as changes in knee pain and/or knee function and/or subjects disease activity according to OMERACT OARSI criteria.;Timepoint(s) of evaluation of this end point: To be evaluated at each visit except: - Immunoassays and clinical chemistry which are evaluated at two timepoints for each treatment period (V0, V2 and V3, V5); - MRI which is evaluated at two timepoints for the second treatment period only (V3 and V6). | — |
