Dapagliflozin Effects on Hypoglycemia
a study on Diabetes
The purpose of this research study will be to test and evaluate if dapagliflozin has an effect on the amount of glucagon (a hormone produced by the pancreas and stomach that stimulates liver glucose production) produced by the body and if that change will improve recovery time from hypoglycemia (low blood sugar) in participants with Type 1 Diabetes.
Evaluating the Effect of Dapagliflozin, an SGLT-2 Inhibitor, on the Counterregulatory Response to Hypoglycemia in Individuals With Type 1 Diabetes
The purpose of this research study will be to test and evaluate if dapagliflozin has an effect on the amount of glucagon (a hormone produced by the pancreas and stomach that stimulates liver glucose production) produced by the body and if that change will improve recovery time from hypoglycemia (low blood sugar) in participants with Type 1 Diabetes. The study is a blinded, placebo-controlled, crossover design, where participants will receive dapagliflozin during one treatment period and placebo during a separate treatment period with neither the study team nor participants knowing what they are receiving at any given time. Participants will have 9 clinic visits over the course of 14-16 weeks, with 3 of those visits being overnight stays. The overnight stays are intended to control blood sugars in a normal state throughout the night and then participants will complete a hypoglycemic challenge the following morning. The body's response to the hypoglycemic challenge will provide the information needed to determine if dapagliflozin had an effect on recovery time from hypoglycemia.
