Brief Summary:

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.

Drug Information available for: Liraglutide

Arm Intervention/treatment
Experimental: 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.

Drug: Liraglutide 3 mg (Saxenda)
Placebo Comparator: 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.

Drug: Liraglutide 3 mg placebo



Primary Outcome Measures :
  1. Change in the degree of inflammation in the knee-joint (Greyscale-score) [ Time Frame: 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)


Secondary Outcome Measures :
  1. Change in knee-joint effusion [ Time Frame: Week 0 to 52 ]
    Change in effusion will be assessed via the US knee OA musculoskeletal ultrasound score (MUS) score (Riecke BF et al.)

  2. Change in the degree of inflammation in the knee-joint (Greyscale-size) [ Time Frame: Week 0 to 52 ]
    Change will be assessed by grey-scale ultrasound in the suprapatellar, the medial, and the lateral recess´ (sum of size-scores (mm) of these three positions)

  3. Change in the degree of inflammation in the knee-joint (Doppler-score) [ Time Frame: Week 0 to 52 ]
    Change will be assessed by Doppler ultrasound in the suprapatellar, the medial, and the lateral recess´ (sum-score (0-9), derived from these three positions)
