Multi-parametric Imaging of the Knee in Obese Patients With Knee Osteoarthritis; Weight Loss
An observational study of Osteoarthritis and Obesity, run by Henrik Gudbergsen at 1 site in Denmark.
Trial 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 (NCT02905864). In the parent trial, patients will be subjected to an 8-week diet intervention phase including a low-calorie diet and dietetic counseling… Read more about this study

About this study
Official title: Multi-parametric Imaging of the Knee in Obese Patients With Knee Osteoarthritis Following a Significant Weight Loss, Investigating the Impact on Inflammation (A Substudy to "Effect of Liraglutide on Body Weight and Pain in Overweight or Obese Patients With Knee Osteoarthritis: A Randomised, Double Blind, Placebo-controlled, Parallel Group, Single-centre Trial" (NCT02905864)
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 (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 any changes in MRI associated with the initial 8-week weight loss intervention, and the value of CT scans in predicting the effect of weight loss.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Intensive dietary interventionDietary supplement
Participants receive a hypo-caloric formula diet containing 800 to 1,000 kcal/day. The formula diet consists of ready-to-use meal bars and powders to mix with water to make shakes, soups, or porridge. The weight loss programme consists of an 8-week period with full meal replacement by a standard liquid energy intake protocol. To facilitate compliance with the programme, participants will be scheduled for weekly facility-based group sessions with 6-8 participants led by a dietician. The recommendations for daily nutrient intake will be met.
| Study group | Role | What they receive |
|---|---|---|
| Intensive dietary intervention | Supervised dietary weight loss program lasting 8 weeks. Receives: Dietary Supplement: Intensive dietary intervention |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in the degree of inflammation in the knee-joint (DCE-MRI)
Change will be assessed via a dynamic contrast enhanced MRI evaluation of corpus hoffa (Ballegaard C et al. and Riis RG et al.)
Measured: Week -8 to 0
Secondary outcomes (5)
Change in the degree of inflammation in the knee-joint (CE-MRI)
Change will be assessed via a static contrast enhanced MRI evaluation of the level of synovitis in the knee-joint (11 sites scored 0-2, ad modum Guermazi et al.)
Measured: Week -8 to 0
Change in the degree of inflammation in the knee-joint (MRI)
Change will be assessed via a conventional MRI evaluation of the level of synovitis and effusion (combined) in the knee-joint (MOAKS)
Measured: Week -8 to 0
Change in cartilage composition
Change will be assessed via T2-maps of cartilage in the weight-bearing parts of the knee-joint (ROI)
Measured: Week -8 to 0
Change in bone marrow lesions (BML)
Change will be assessed via the MRI knee scoring system MOAKS; BML sum-score
Measured: Week -8 to 0
Prediction of clinical symptoms (KOOS pain) by the level of crystal deposition on dual-energy CT at week 0
Crystal deposition will be evaluated via dual-energy CT
Measured: Week 0

Clinical summary

Questions about this trial
What is this clinical trial studying?
An observational study of Osteoarthritis and Obesity, run by Henrik Gudbergsen at 1 site in Denmark.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 25 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in the degree of inflammation in the knee-joint (DCE-MRI) (time frame: Week -8 to 0). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Mar 2019.
