Changes in Skin Autoflouresence Following Weight Loss and Maintenance Using Liraglutide in Knee Osteoarthritis

Phase 4

Completed

• Conditions: Osteoarthritis, Knee
• Interventions: Drug: Liraglutide 3 mg placebo; Drug: Liraglutide 3 mg (Saxenda)

• Registration Number: NCT02910570
• Lead Sponsor: Parker Research Institute

Brief Summary

This is sub-study to a randomised, double blind, placebo-controlled, parallel group, and single-centre trial investigating the effect of liraglutide on body weight and pain in overweight or obese patients with knee osteoarthritis (NCT02905864).

In the parent trial patients will be subjected to a run-in diet intervention phase (week -8 to 0) including a low-calorie diet and dietetic counselling. At week 0 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 sub-study of the parent trial only involves an additional assessment of skin auto fluorescence (AGE concentration) in the preallocation phase and in the main trial phase, i.e. from enrollment (defined as signature of informed consent) to treatment allocation (visits -Tx and T0 in the parent trial visit schedule) and from allocation to end of trial (visits T0 and T15 in the parent trial visit schedule).
