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 weight loss, and whether it will be made widely available to all Canadians trying to manage obesity.
