V1(Day 3): safety visit (3 days after V0) * Objective examination, including measurement of vital parameters (weight, diastolic/systolic blood pressure, heart rate). * Safety evaluation and AEs recording and Concomitant Therapies * Checking the completion of the daily diary. V2 (V2, week 2 ± 2 days) follow-up visit: * Objective examination, including measurement of vital parameters (weight, diastolic/systolic blood pressure, heart rate). * Checking the completion of the daily diary. * Administration of the global symptom relief questionnaire (CGI- I). * Administration of the WOMAC Pain questionnaire. * Recording of adverse events and concomitant therapies. * Instruction to fill in the daily diary via web app (smart phone) to report the use of all concomitant therapies. If patient is not able to use web app, a paper copy will be given. V3 (V3, week 4 ± 2 days): follow-up visit: * Objective examination, including measurement of vital parameters (weight, diastolic/systolic blood pressure, heart rate). * Checking the completion of the daily diary. * Administration of the global symptom relief questionnaire (CGI- I). * Questionnaire administration: WOMAC Pain and Function, SF-36. * Recording of adverse events and concomitant therapies. * Instruction to fill in the daily diary via web app (smart phone) to report the use of all concomitant therapies. If patient is not able to use web app, a paper copy will be given. V4 (V4, week 12 ± 2 days) follow-up visit: * Physical examination, including measurement of anthropometric parameters and vital signs (height, weight, diastolic / systolic pressure, heart rate) * Check of daily diary * Administration of the global symptom relief questionnaire (CGI- I). * Questionnaire administration: WOMAC Pain and Function, SF-36. * Recording of adverse events and concomitant therapies. * Instruction to fill in the daily diary via web app (smart phone) to report the use of all concomitant therapies. If patient is not able to use web app, a paper copy will be given. V5 (V5, week 24 ± 3 days) end-of-study or premature discontinuation visit: * Objective examination, including measurement of vital parameters * Blood tests: blood glucose, creatinine, blood count with formula,AST, ALP, calcemia, potassium, sodium, C-reactive protein, total bilirubin. Urine examination. * Check of completion of the daily diary. * Administration of the global symptom relief questionnaire (CGI- I). * Questionnaire administration: WOMAC Pain and Function, SF-36. * Recording of adverse events and concomitant therapies.

Eligibility

Sex: ALLMin age: 40 Years

Medical Language ↔ Plain English

Inclusion Criteria: 1. Signed Informed Consent 2. Patient of both sexes over 40 years of age 3. Diagnosis of primary osteoarthritis of the knee according to the criteria of the American College, radiologically confirmed, i.e., one or more osteophytes and a measurable joint space on a standard radiograph taken within 3 months prior to screening. 4. Score ≥2 in the target knee on a Likert scale at WOMAC pain question 1 (i.e. pain while walking on a flat surface) at the V-1 screening visit (to be confirmed at the V0 baseline visit). The target knee is defined as the knee with osteoarthritis in the case of unilateral pathology or the only one with this criterion in the case of bilateral pathology. 5. Severity grade of arthrosis 2 or 3 according to Kellgren \& Lawrence classification. 6. Be willing to maintain stable eating habits and lifestyle throughout the study period Exclusion Criteria: 1. Intake of analgesics, NSAIDs or opioids within 5 days prior to the start of the run-in (i.e. prior to V-1). 2. Body Mass Index (BMI) ≥ 30 kg/m2 . 3. Pregnant women. 4. Intra-articular visco supplementation in the target knee in the preceding 9 months. 5. Cycle of treatment with systemic corticosteroids or intra-articular corticosteroid injection in any joint in the 3 months prior to screening. 6. Symptomatic arthrosis of the contralateral knee with a score ≥3 on a Likert scale to WOMAC pain question 1 (pain while walking on a flat surface) at V-1 (to be confirmed at V0), or severe symptomatic hip arthrosis. 7. Significant deformity: genu varum, ligament laxity or meniscus instability. 8. Presence of autoimmune diseases (excluding chronic autoimmune thyroiditis) or other chronic inflammatory processes (e.g. rheumatoid arthritis, ongoing infections, gout). 9. Ongoing infections. 10.
