Study summary

This study will look at participants body weight from the start to the end of the study. It will also look at how much pain participants have in participants knee from the start to the end of the study and how this affects participants daily life. This is to compare the effect on body weight and pain in the knee in people taking semaglutide with people taking "dummy" medicine. Participants will either get semaglutide or "dummy" medicine. Which treatment participants get is decided by chance.

Participants will need to take 1 injection once a week. The study medicine is injected with a thin needle in a skin fold in the stomach, thigh or upper arm. During the study, participants will have talks with study staff about how to eat healthy food and how to be more physically active. The study will last for about 1 ½ years. Participants will have 14 clinic visits with the study staff. At the first clinic visit participants will have a blood sample taken. Participants will have an X-ray of participants knee taken at the first visit. If participants have had an X-ray recently, this may not be needed.

At 6 of the clinic visits participants cannot take pain medications for 3 days before the visit. Participants cannot take part if participants have had a joint replacement surgery in participants knee. Participants cannot take part if participants have or have had diabetes. Women: Women cannot take part if pregnant, breast-feeding or plan to become pregnant during the study period.

What researchers measure

Primary outcomes

  1. Percentage Change in Body Weight

    Percentage change in body weight from baseline (week 0) to end of treatment (week 68) is presented. The outcome measure was evaluated based on the data from in-trial period. In-trial period was defined as the uninterrupted time interval from date of randomization to date of last contact with trial site.

    Time frame: Baseline (week 0), end of treatment (week 68)

  2. Change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Score

    WOMAC is a disease-specific patient-reported outcome measure designed to assess changes in symptoms and lower extremity functioning associated with treatment in patients with osteoarthritis of the hip and/or knee. WOMAC is a 24 item questionnaire which assesses clinically important, participant-relevant symptoms in area of pain, stiffness, and physical function in participants with osteoarthritis (OA). It consists of 3 subscales: pain, stiffness and physical function. The WOMAC raw pain score is derived as the sum of the 5 item scores in the pain domain. It will be normalised and expressed on a 0-100 scale. This is done by dividing raw score by the highest possible value of the raw score for the pain domain (i.e. 50) and multiplying by 100. Higher scores indicate worse outcome. The outcome measure was evaluated based on the data from in-trial period. In-trial period was defined as the uninterrupted time interval from date of randomization to date of last contact with trial site.

SecondaryChange in WOMAC Physical Function Score

Change in WOMAC physical function score is presented. WOMAC is a 24 item questionnaire which assesses clinically important, participant-relevant symptoms in area of pain, stiffness, and physical function in participants with osteoarthritis (OA). It consists of 3 subscales: pain, stiffness and physical function. WOMAC physical function is 17-item questionnaire used to assess degree of difficulty experienced due to OA in knee. It is calculated as the sum of the 17 item scores in the physical function domain. It is normalized and expressed on a 0-100 scale. This is done by dividing raw score by the highest possible value of the raw score for the physical function domain (i.e. 170) and multiplying by 100. Higher scores indicate worse outcome. The outcome measure was evaluated based on the data from in-trial period. In-trial period was defined as the uninterrupted time interval from date of randomization to date of last contact with trial site.

SecondaryChange in Short Form 36 (SF-36) Physical Functioning Score

SF-36 is self-administered questionnaire that measures each of following 8 health domains: physical functioning, role limitations due to physical problems (role-physical), social functioning, bodily pain, mental health, role limitations due to emotional problems (role-emotional), vitality, and general health perception. There are also 2 component scores derived from the 8 subscale scores: physical component summary (including physical functioning, role-physical, bodily pain and general health) and mental component summary (including vitality, social functioning, role-emotional and mental health).
