简要总结
This is a substudy to a randomised trial investigating the effect of liraglutide on body weight and pain in overweight or obese patients with knee osteoarthritis (OA) (NCT02905864). In the parent trial, patients will be subjected to an 8-week diet intervention phase including a low-calorie diet and dietetic counseling, after which patients will be randomised to receive either liraglutide 3 mg or liraglutide 3 mg placebo as an add-on to dietetic guidance on re-introducing regular foods and a focus on continued motivation to engage in a healthy lifestyle.
This substudy aims to investigate the impact of, and subsequent change of, joint inflammation and clinical symptoms, in obese patients with knee osteoarthritis following a randomisation to Liraglutide 3 mg or Liraglutide 3 mg placebo treatment between weeks 0-52.

研究组 & 干预措施
Liraglutide 3 mg
Arm description: Subjects will be up titrated to liraglutide 3 mg once daily (QD) and stay on that dose for the remainder of the 52-week drug intervention period.
Drug: Liraglutide 3 mg QD administered in a 6 mg/mL, 3 mL pen for subcutaneous injection.
Dose escalation scheme: Initial dosage of 0.6 mg per day, escalated bi-weekly by 0.6 mg to 3 mg per day over a total of 8 weeks.
干预措施: Liraglutide 3 mg (Saxenda) (Drug)
Liraglutide 3 mg placebo
Arm description: Subjects will be up titrated to liraglutide 3 mg placebo QD and stay on that dose for the remainder of the 52-week drug intervention period.
Drug: Liraglutide 3 mg placebo QD administered in a 6 mg/mL drug equivalent volumes, 3 mL pen for subcutaneous injection.
Dose escalation scheme: Initial dosage of a 0.6 mg drug equivalent volume per day, escalated bi-weekly by an 0.6 mg drug equivalent volume per day to a 3 mg drug equivalent volume per day over a total of 8 weeks.
干预措施: Liraglutide 3 mg placebo (Drug)
结局指标
主要结局
Change in the degree of inflammation in the knee-joint (Greyscale-score)
时间窗: Week 0 to 52
Change will be assessed by grey-scale ultrasound (US) in the suprapatellar, the medial, and the lateral recess´ (sum-score (0-9), derived from these three positions)
次要结局
- Change in knee-joint effusion(Week 0 to 52)
- Change in the degree of inflammation in the knee-joint (Greyscale-size)(Week 0 to 52)
- Change in the degree of inflammation in the knee-joint (Doppler-score)(Week 0 to 52)
