About this study

Are you Struggling With Obesity and Knee Pain Caused by Osteoarthritis?

The YDAN master protocol will support two independent studies, J3R-MC-YOA1 and J3R-MC-YOA2. Each study will investigate how well and safely Eloralintide (LY3841136) works in adults with obesity or overweight who have osteoarthritis (OA) of the knee with pain. Participation in the study will last about 75 weeks, including screening.

Would you like to take part?

As a volunteer in a research study, you’ll receive study-related medical care from the study doctor and regular follow-up of your health to monitor the effectiveness of the care you’ll receive. The results of this research will be used to find out if the investigational medication being studied will be of benefit to others struggling with obesity and osteoarthritis related pain, and whether it will be made widely available to all Canadians trying to manage these conditions. Study volunteers are an important part of moving medical care forward.

Who may qualify

You may qualify if
  • Have a body mass index (BMI) of 27 kilograms per square meter (kg/m²) or higher at screening
  • Have a stable body weight (less than 5% body weight change) for 90 days prior to screening
  • Have tried at least once to lose weight through diet but were unsuccessful
  • Have osteoarthritis of the knee and at least one of the following conditions:
    • Be over 50 years old
    • Have morning knee stiffness that lasts about 30 minutes
    • Have a crackling or grinding sound or feeling in the knee
This study may not be a fit if
  • Have a prior or planned surgical treatment for obesity (liposuction, cryolipolysis, or abdominoplasty allowed if performed greater than 1 year before screening)
  • Have a prior or planned endoscopic procedure and/or device-based therapy for obesity (prior device-based therapy acceptable if device removal was more than 6 months prior to screening)
  • Have type 1 diabetes, type 2 diabetes, or any other type of diabetes
  • Have an active knee infection
  • Have had within 90 days prior to screening:
    • heart attack
    • stroke
    • coronary artery revascularization
    • unstable angina, or
    • hospitalization due to congestive heart failure
  • Have a history or diagnosis of New York Heart Association Functional Classification Class IV congestive heart failure
  • Have taken medications or alternative remedies intended for weight loss within 90 days of screening
Every study has additional criteria the research site will review with you.

Common questions

Do I have to decide now?
No. Answering the questions is not a commitment — it simply lets the research team see whether this study may be appropriate and contact you to talk it through.
Will it cost me anything?
No. Study visits and study assessments are provided at no cost, and reasonable travel may be reimbursed where applicable.
What happens after I submit the form?
A member of the research team reviews your answers and contacts you — usually within two business days — to answer questions and review the next steps.
Could I receive a placebo?
Some studies compare a treatment with a placebo. Whether this study does is explained clearly during informed consent, before you decide anything.
Can I leave the study after it starts?
Yes. Participation is always voluntary. You can withdraw at any time without giving a reason and without it affecting your regular medical care.
