Please note the ANZCTR will be unattended from Friday 24 December 2021 for the holidays. The Registry will re-open on Monday 17 January 2022. Submissions and updates will not be processed during that time.

For new and updated trial submissions, we are processing trials as quickly as possible and appreciate your patience. We recommend submitting your trial for registration at the same time as ethics submission.

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

Outcomes
Primary outcome [1] 0 0
Adjusted Mean Change From Baseline in Glycosylated Haemoglobin (HbA1c): Comparison of Dapagliflozin 10 mg Plus Saxagliptin 2.5 mg and Placebo at Week 24 - HbA1c was analysed at baseline and every 4 weeks during the 24-week treatment period. Only measurements prior to rescue or treatment discontinuation were analysed. The adjusted mean change from baseline at Week 24 was analysed using a mixed model repeated measures (MMRM) model.
Timepoint [1] 0 0
Baseline and Week 24
Primary outcome [2] 0 0
Adjusted Mean Percent Change From Baseline in Urine Albumin-to-Creatinine Ratio (UACR) at Week 24 - UACR was analysed at baseline and every 4 weeks during the 24-week treatment period. All measurements regardless of rescue medication or treatment discontinuation were analysed. UACR values were first transformed to logarithms and the results were based on exponentiation of model estimates and expressed as adjusted mean percent change from baseline at Week 24.
Timepoint [2] 0 0
Baseline and Week 24
Secondary outcome [1] 0 0
Adjusted Mean Percent Change From Baseline in Total Body Weight at Week 24 - Total body weight was measured in kilograms (kg) at baseline and at Week 1 then every 4 weeks during the 24-week treatment period. All measurements regardless of rescue medication or treatment discontinuation were analysed. Total body weight values were first transformed to logarithms and the results were based on exponentiation of model estimates and expressed as adjusted mean percent change from baseline at Week 24.

Secondary outcome [2] 0 0
Adjusted Mean Change From Baseline in Fasting Plasma Glucose (FPG) at Week 24 - FPG was analysed at baseline and Week 1 then every 4 weeks during the 24-week treatment period. Only measurements prior to rescue or treatment discontinuation were analysed. The adjusted mean change from baseline at Week 24 was analysed using a MMRM model.
Timepoint [2] 0 0
Baseline and Week 24
Secondary outcome [3] 0 0
Percentage of Patients Achieving at Least 30% Reduction in UACR at Week 24 - The percentage of patients meeting the criteria of at least a 30% reduction in UACR, was analysed using a logistic regression model. If no measurement was available at Week 24 the last available post-baseline measurement was carried forward (Last Observation Carried Forward [LOCF]).
Timepoint [3] 0 0
From baseline up to Week 24
Secondary outcome [4] 0 0
Percentage of Patients Achieving a Reduction in HbA1c of Less Than 7.0% at Week 24 - The percentage of patients meeting the criteria of a less than 7% reduction in HbA1c, was analysed using a logistic regression model. If no measurement was available at Week 24 the last available post-baseline measurement was carried forward (LOCF). Only measurements prior to rescue or treatment discontinuation were analysed.
Timepoint [4] 0 0
From baseline to Week 24
Secondary outcome [5] 0 0
Adjusted Mean Change From Baseline in Seated Systolic Blood Pressure (SBP) at Week 24 - Seated SBP was analysed at baseline, Week 1 and every 4 weeks during the 24-week treatment period. All measurements regardless of rescue medication or treatment discontinuation were analysed. The adjusted mean change from baseline at Week 24 was analysed using a MMRM model.

Secondary outcome [6] 0 0
Adjusted Mean Change From Baseline in HbA1c: Comparison of Dapagliflozin 10 mg and Placebo at Week 24 - HbA1c was analysed at baseline and every 4 weeks during the 24-week treatment period. Only measurements prior to rescue or treatment discontinuation were analysed. The adjusted mean change from baseline at Week 24 was analysed using a MMRM model.

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)
