Exclusion Criteria

• Incomplete online screening surveys
• Participants that are non-responders after completing the screening survey but before being enrolled
• Women who are pregnant or breastfeeding, or women of childbearing potential not willing to use contraceptive methods for the duration of the study
• Bilateral symptomatic knee OA if the patient-reported pain intensity in the contralateral knee is >= 30 on a 0-100 VAS
• Significant injury in the study knee that led to substantial loss of function or surgeries within the past 6 months
• Prior knee joint replacement or high tibial osteotomy in the study knee
• Surgery on the study knee within the past 12 months
• Planned surgery for the study knee in the next 24 months
• History of crystalline arthropathy, autoimmune arthritis, hemochromatosis or fibromyalgia. Except for the following conditions:
i. participants diagnosed with gout are eligible for the study as long as the condition is being appropriately treated and they have not experienced flare-ups for at least 12 months
ii. participants diagnosed with hemochromatosis but with normal iron levels for at least 12 months are eligible for the study
• Signs of acute knee joint inflammation (i.e., red, swollen and hot) and/or abnormal synovial fluid suggestive of either crystal or infection;
• Any painful muscular or neurological condition of the lower limb that, in the opinion of the investigators, is the main contributor to the pain and/or loss of function in the study knee which may interfere with the self-reported assessment
• Immunosuppression or acute infective processes
• Cancer or other tumour-like lesions, except for non-melanoma skin cancer which has been removed and not active within the past 3 years

• Participation in another clinical trial and/or treatment received with any investigational agent within 30 days before enrolment
• Any unstable concurrent clinically significant acute, chronic medical conditions or abnormal laboratory findings that, in the judgment of the Investigator, would jeopardise the safety of the participant, interfere with study objectives or affect the participant’s compliance
