A 52-week International, Multicenter Trial With a Long -Term Extension to Evaluate Saxagliptin With Dapagliflozin in Combination With Metformin Compared to Glimepiride in Combination With Metformin in Type 2 Diabetes Who Have Inadequate Glycemic Control on Metformin Alone

- Registration Number
- NCT02419612
- Lead Sponsor
- AstraZeneca
- Brief Summary
This clincial trial is evaluating if the co-administration of saxagliptin and dapagliflozin, in addition to metformin, results in better glycemic control, as measured by HbA1c, over a treatment period of 52 weeks, compared to the addition of glimepiride to metformin in subjects with Type 2 Diabetes Mellitus who have inadequate glycemic control on Metformin Alone. We will compare the change from baseline in HbA1c achieved with saxagliptin, in co-administration with dapagliflozin, added to current background therapy with metformin compared to glimepiride added to current background therapy with metformin ≥1500 mg at Week 52.

- Primary Outcome Measures
Name Time Method Change From Baseline in Hemoglobin A1c (HbA1c) at Week 52 Baseline and Week 52 To examine whether the mean change from baseline in HbA1c with co-administered saxagliptin 5 mg and dapagliflozin 10 mg plus metformin is superior to titrated glimepiride plus metformin after 52 weeks of double-blind treatment.
- Secondary Outcome Measures
Name Time Method Change From Baseline in Total Body Weight at Week 52 Baseline and Week 52 To examine whether the mean change from baseline in total body weight with co-administered saxagliptin 5 mg and dapagliflozin 10 mg plus metformin is superior to titrated glimepiride plus metformin after 52 weeks of double-blind treatment.
Percentage of Subjects Achieving a Therapeutic Glycemic Response, Defined as HbA1c < 7.0%, at Week 52 At Week 52 Therapeutic glycemic response was defined as HbA1c \<7.0%. Subjects rescued or discontinued prior to, and subjects with missing measurements at Week 52 were treated as non-responders. The percentage of subjects with a therapeutic glycemic response is based on the logistic regression method with adjustment for baseline HbA1c.
Change From Baseline in Systolic Blood Pressure (SBP) at Week 52 Baseline and Week 52 To examine whether the change from baseline in SBP with co-administered saxagliptin 5 mg and dapagliflozin 10 mg plus metformin is superior to titrated glimepiride plus metformin after 52 weeks of double-blind treatment.
Percentage of Subjects With Treatment Intensification During the 52-week Short-term Treatment Period Up to Week 52 Treatment intensification was defined as the addition of insulin or other glucose-lowering agent for rescue therapy or discontinuation for lack of glycemic control. Time to treatment intensification was censored after the 52-week treatment period if treatment intensification had not occurred by then. Subjects rescued at Week 52 were counted as having an event for the analysis. The values presented are the percentage of subjects requiring the addition of insulin or other glucose-lowering agent for rescue therapy or discontinuation for lack of glycemic control during the 52-week short -term treatment period.
Percentage of Subjects With Treatment Intensification During the 156-Week Short-term Plus Long-Term Treatment Period. Up to Week 156 Treatment intensification was defined as the addition of insulin or other glucose-lowering agent for rescue therapy or discontinuation for lack of glycemic control. Time to treatment intensification was censored after 156-week treatment period if treatment intensification had not occurred by then. Subjects rescued at Week 156 were counted as having an event for the analysis. The values presented are the percentage of subjects requiring the addition of insulin or other glucose-lowering agent for rescue therapy or discontinuation for lack of glycemic control during the 156-week treatment period.
Percentage of Subjects Achieving a Therapeutic Glycemic Response, Defined as HbA1c < 7.0%, at Week 156 At Week 156 Therapeutic glycemic response was defined as HbA1c \<7.0%. Subjects rescued or discontinued prior to, and subjects with missing measurements at Week 156 were treated as non-responders. The percentage of subjects with a therapeutic glycemic response is based on the logistic regression method with adjustment for baseline HbA1c.
Time to Treatment Intensification During the 156-Week Short-term Plus Long-Term Treatment Period. Up to Week 156 Treatment intensification was defined as the addition of insulin or other glucose-lowering agent for rescue therapy or discontinuation for lack of glycemic control. Time to treatment intensification was censored after 156-week treatment period if treatment intensification had not occurred by then. Subjects rescued at Week 156 were counted as having an event for the analysis. Time to treatment intensification curves were generated using Kaplan-Meier estimates and compared using a Cox proportional hazards model.
