Research + Clinical Trials


A Study to Evaluate the Effect of Dapagliflozin on Renal Outcomes and Cardiovascular Mortality in Patients with Chronic Kidney Disease (Forxiga)

Dapagliflozin (ForxigaTM/FarxigaTM) is currently used for treating type 2 diabetic patients worldwide and is approved by the U.S. Food and Drug Administration (FDA) for type 2 diabetes. Because it is being evaluated in subjects with chronic kidney disease, with or without type 2 diabetes, its use in this study is considered investigational. Previous data from dapagliflozin and similar type of medications indicate that they might have beneficial effects on chronic kidney disease. Dapagliflozin decreases blood sugar in diabetic patients but should not influence blood sugar if you do not have diabetes. This research study is carried out to see if dapagliflozin is effective in chronic kidney disease by preventing the gradual loss of kidney function and in the long run to improve the survival for patients with chronic kidney disease.
