Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
The purpose of this clinical research study is to determine whether dapagliflozin alone or in combination with saxagliptin can decrease albuminuria and improve glycemic control in patients with Type 2 diabetes, albuminuria and renal impairment (CKD). The study is planned to randomize a total of 450 patients (150 patients per treatment arm)
