Osteoarthritis, Overweight or Obesity

Brief summary

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.
