Drug combo shows promise for weight loss in severe obesity
NCT ID NCT03968224
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether adding dapagliflozin to metformin helps people with prediabetes or type 2 diabetes and severe obesity lose more weight than metformin alone. About 160 participants took either both drugs or just metformin for up to 12 months. The main goal was to see if the combination leads to at least 10% more weight loss. The study also checked changes in blood pressure and waist size.
