A Double-blind, Placebo-controlled, Randomized Study to Evaluate the Efficacy and Safety of KBP-336 As an Adjunct to Diet and Exercise in Obese Individuals with Osteoarthritis of the Knee
The goal of this clinical trial is to learn if KBP-336 works to treat pain in osteoarthritis in individuals living with obesity. It will also learn about the effects on other parameters, such as quality of life and metabolism, as well as safety of KBP-336. The main questions it aims to answer are: * Does KBP-336 lower knee pain from osteoarthritis in individuals with obesity * Does KBP-336 lower bodyweight in the same population. Researchers will compare KBP-336 to a placebo (a look-alike substance that contains no drug) to see if KBP-336 works to pain and obesity Participants will: * Take KBP-336 or a placebo every week for 6 months * Visit the clinic once every 2 weeks for checkups and tests * Keep a diary of their symptoms and the amount of medication they use in addition to KBP-336
