Effect of dapagliflozin as an adjunct to insulin over 52 weeks in individuals with type 1 diabetes: post-hoc renal analysis of the DEPICT randomised controlled trials.
Summary
The purpose of this study is to determine if adding dapagliflozin to insulin is a safe and effective therapy to improve glycemic control in patients with type 1 diabetes.
