Response: We showed:
1) Weight loss is robust, though slightly less that in the weight loss studies. We expect this because we were not pushing the doses to top-dose in all cases and because it was NOT a weight loss study.
2)We showed that the weight loss was maintained for 4 years. This observation period is twice as long as prior studies.
3) We showed that all subgroups (age, sex starting BMI, race, ethnicity, baseline health indicators) could achieve robust weight loss.
4) At 2 years, 12% of people on semaglutide reached normal weight status and more than 55% no longer qualified as having obesity BMI class, both observations much higher than placebo.
WeightControl.com: What should readers take away from your report?
Response: The long term data is reassuring. We now have more evidence for semaglutide weight loss efficacy in older, sicker individuals. There were no safety issues uncovered when we analyzed the data by BMI class.
WeightControl.com: What recommendations do you have for future research as a result of this work?
1. We need to better understand the mechanism of reducing cardiovascular events.
2. It will be important to determine if there is a role in primary prevention of cardiovascular events.
3. It will be important to see if other GLP-1 receptor agonists produce this benefit.
