Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of EFEX-OA-02 is to explore how running, cycling, exercise simulation and resting acutely influence collagen and proteoglycan homeostasis in OA, as reflected by changes in collagen and proteoglycan levels in urine and serum.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

The study period will be 4 weeks. In each week, the subjects will undergo a different physical activity intervention. The order of the interventions will be randomized. The interventions will be separated by a minimum of 4 days. Inteventions: Cycling, Running, exercise-simulation with inotropy and resting.

4. Previous arthroplasty of knee or hip.
5. Intention to have major surgery during the timeframe of the study.
6. Secondary OA related to e.g. any known trauma including cruciate ligament tears, meniscus tears and cartilage damage, dysplasia, aseptic osteonecrosis, acromegaly, Paget disease, Stickler syndrome, hemochromatosis, gout, chondrocalcinosis (pseudogout).
7. Current treatment with beta-receptor adrenergic antagonists (beta-blockers), MAO inhibitor, systemic corticosteroid treatment in doses equivalent to \> 10 mg prednisolone per day, or vitamin K antagonists, new oral anticoagulants, fractionated and non-fractionated heparin.

3. Categorized as being very difficult to draw blood from, as evaluated by the investigator.
4. Current alcohol abuse and/or inability to refrain from intake of alcoholic beverages for 24 hours prior to the study intervention.
5. Other factors, e.g. self-reported drug abuse, which in the opinion of the investigator may interfere with the performance of the study.
