About this study

Official title: Effect of Subcutaneous Semaglutide 2.4 mg Once-weekly Compared to Placebo in Subjects With Obesity and Knee Osteoarthritis

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 is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: 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.

    Measured: Baseline (week 0), end of treatment (week 68)

Secondary outcomes (23)
  1. Percentage of Participants Achieving Body Weight Reduction Greater Than or Equal to (≥) 5 Percent (%) (Yes/No)

  17. Percentage of Participants Achieving WOMAC Pain Reduction ≥ 30% (Yes/No)

    Percentage of participants who achieved ≥30% WOMAC pain reduction (yes/no) is presented. In the reported data, 'Yes' infers percentage of participants who have achieved ≥30% WOMAC pain reduction whereas 'No' infers percentage of participants who have not achieved ≥30% WOMAC pain reduction. WOMAC raw pain score is derived as sum of 5 item scores in pain domain. It will be normalized and expressed on 0-100 scale. This is done by dividing raw score by highest possible value of raw score for 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.

    Measured: From baseline (week 0) to end of treatment (week 68)

In-trial period was defined as the uninterrupted time interval from date of randomization to date of last contact with trial site.

    Measured: From baseline (week 0) to end of treatment (week 68)

  19. Percentage of Participants Achieving Threshold for Clinically Meaningful Within-participant Change in WOMAC Pain Score (Yes/No)

    Percentage of participants who achieved threshold for clinically meaningful within-participant change in WOMAC pain score from baseline (week 0) to end of treatment (week 68) is presented. The threshold refers to the decrease of at least 37.3 in the WOMAC pain score and it is derived based on 1-category improvement on patient global impression of status (PGI-S) scale. In reported data, 'Yes' infers percentage of participants who have achieved threshold whereas 'No' infers percentage of participants who have not achieved threshold. WOMAC raw pain score is derived as sum of 5 item scores in pain domain. It will be normalized and expressed on 0-100 scale. This is done by dividing raw score by highest possible value of raw score for pain domain (i.e. 50) and multiplying by 100. Higher scores=worse outcome. Outcome measure was evaluated based on data from in-trial period and it was defined as uninterrupted time interval from date of randomization to date of last contact with trial site.

    Measured: From baseline (week 0) to end of treatment (week 68)

  21. Percentage of Participants Achieving Threshold for Clinically Meaningful Within-participant Change in SF-36 Physical Functioning Score (Yes/No)

    Percentage of participants who achieved threshold for clinically meaningful within-participant change in SF-36 physical function score is presented. Threshold refers to increase of at least 11.4 in SF-36 physical functioning score \& it is derived based on 1-category improvement on PGI-S scale. 'Yes' infers percentage of participants who achieved threshold; 'No' infers percentage of participants who have not achieved threshold. SF-36: self-administered questionnaire that measures each of following 8 health domains: physical functioning, role limitations due to physical problems, social functioning, bodily pain, mental health, role limitations due to emotional problems, vitality, \& general health perception. Each SF-36 domain and component summary score ranges from 0-100, higher scores mean better participant health status. Outcome measure was evaluated based on data from in-trial period: uninterrupted time interval from date of randomization to date of last contact with trial site.

    Measured: From baseline (week 0) to end of treatment (week 68)

  22. Percentage of Participants Achieving Pain Intensity (Numerical Rating Scale [NRS]) Reduction ≥ 30% (Yes/No)

    Percentage of participants who achieved ≥30% pain intensity reduction (yes/no) from baseline (week 0) to end of treatment (week 68) is presented. In the reported data, 'Yes' infers percentage of participants who have achieved ≥30% pain intensity reduction whereas 'No' infers percentage of participants who have not achieved ≥30% pain intensity reduction. Response at visit was derived from the pain diary data as an average score over 4 days interval leading up to visit-related washout period for pain medication. Pain intensity was assessed on an 11-point NRS over the past 24 hours (before each specified visit), where a score of 0 indicated "no pain" and a score of 10 indicated "worst possible pain", where higher the score, greater the pain intensity. 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.

    Measured: From baseline (week 0) to end of treatment (week 68)

  23. Percentage of Participants Achieving Pain Intensity (Numerical Rating Scale [NRS]) Reduction ≥ 50% (Yes/No)

    Percentage of participants who achieved ≥50% pain intensity reduction (yes/no) from baseline (week 0) to end of treatment (week 68) is presented. In the reported data, 'Yes' infers percentage of participants who have achieved ≥50% pain intensity reduction whereas 'No' infers percentage of participants who have not achieved ≥50% pain intensity reduction. Response at visit was derived from the pain diary data as an average score over 4 days interval leading up to visit-related washout period for pain medication. Pain intensity was assessed on an 11-point NRS over the past 24 hours (before each specified visit), where a score of 0 indicated "no pain" and a score of 10 indicated "worst possible pain", where higher the score, greater the pain intensity.

A Phase 3 study testing semaglutide 2.4 mg in people with Obesity, run by Novo Nordisk A/S at 122 sites in 11 countries.

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 3 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 17 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 122 sites in United States, Canada, Russia, France, South Africa and 6 more countries. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 Aug 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Percentage Change in Body Weight (time frame: Baseline (week 0), end of treatment (week 68)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05064735, which also lists 1 linked publication.

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?
