  Purpose

Saxagliptin is a new investigational medication being developed for treatment of type 2 diabetes. This study is designed to test the efficacy of once daily saxagliptin in renally impaired patients.


Condition Intervention Phase
Type 2 Diabetes
Drug: Saxagliptin
Drug: Placebo
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator)
Primary Purpose: Treatment
Official Title: A Short-term 12-Week, Multi-centre, Randomized, Parallel-group, Double-blind, Placebo-controlled Study to Evaluate the Treatment Effect of Saxagliptin Compared With Placebo in Adult Patients With Type 2 Diabetes and Renal Impairment (Moderate, Severe, and End-Stage) With an Additional 40-week, Randomized, Double-blind, Placebo-controlled Long-term Observational Period.

Primary Outcome Measures:
  • Absolute Change From Baseline in Glycosylated Haemoglobin A1c (HbA1c) Level to Week 12 Last Observation Carried Forward (LOCF) [ Time Frame: Baseline , Week 12 (LOCF) ] [ Designated as safety issue: No ]
    Adjusted* mean change from baseline in HbA1c achieved with saxagliptin 2.5 mg once daily versus placebo at Week 12 (Full Analysis Set). HbA1c is a continuous measure, the change from baseline for each participant is calculated at the Week 12 value minus the baseline value.


Secondary Outcome Measures:
  • Absolute Change From Baseline in Fasting Plasma Glucose (FPG) to Week 12 (LOCF)- Moderate Renal Impairment Subgroup [ Time Frame: Baseline, Week 12 (LOCF) ] [ Designated as safety issue: No ]
    Adjusted* mean change from baseline in fasting plasma glucose (FPG) achieved with saxagliptin 2.5 mg once daily versus placebo at Week 12 (Full Analysis Set) for the moderate renal impairment subgroup. FPG is a continuous measure, the change from baseline for each participant is calculated at the Week 12 value minus the baseline value.

  • Absolute Change From Baseline in Fasting Plasma Glucose (FPG) to Week 12 (LOCF) - Severe Renal Impairment Subgroup [ Time Frame: Baseline, Week 12 (LOCF) ] [ Designated as safety issue: No ]
    Adjusted* mean change from baseline in fasting plasma glucose (FPG) achieved with saxagliptin 2.5 mg once daily versus placebo at Week 12 (Full Analysis Set) for the severe renal impairment subgroup. FPG is a continuous measure, the change from baseline for each participant is calculated at the Week 12 value minus the baseline value.

  • Absolute Change From Baseline in Fasting Plasma Glucose (FPG) to Week 12 (LOCF) - End-Stage Renal Impairment Subgroup [ Time Frame: Baseline, Week 12 (LOCF) ] [ Designated as safety issue: No ]
    Adjusted* mean change from baseline in fasting plasma glucose (FPG) achieved with saxagliptin 2.5 mg once daily versus placebo at Week 12 (Full Analysis Set) for the end-stage renal impairment subgroup. FPG is a continuous measure, the change from baseline for each participant is calculated at the Week 12 value minus the baseline value.

  • Absolute Change From Baseline in Fasting Plasma Glucose (FPG) to Week 12 (LOCF) - Moderate Renal Impairment Subgroup [ Time Frame: Baseline, Week 12 (LOCF) ] [ Designated as safety issue: No ]
    Adjusted* mean change from baseline in fasting plasma glucose (FPG) achieved with saxagliptin 2.5 mg once daily versus placebo at Week 12 (Full Analysis Set) for the moderate renal impairment subgroup. FPG is a continuous measure, the change from baseline for each participant is calculated at the Week 12 value minus the baseline value.

  • Absolute Change From Baseline in Glycosylated Haemoglobin A1c (HbA1c) Level to Week 52 [ Time Frame: Baseline , Week 52 ] [ Designated as safety issue: No ]
    Adjusted* mean change from baseline in HbA1c achieved with saxagliptin 2.5 mg once daily versus placebo at Week 52 (Full Analysis Set). HbA1c is a continuous measure, the change from baseline for each participant is calculated at the Week 52 value minus the baseline value.

  • Absolute Change From Baseline in Fasting Plasma Glucose (FPG) to Week 52 - Moderate Renal Impairment Subgroup [ Time Frame: Baseline, Week 52 ] [ Designated as safety issue: No ]
    Adjusted* mean change from baseline in fasting plasma glucose (FPG) achieved with saxagliptin 2.5 mg once daily versus placebo at Week 52 (Full Analysis Set) for the moderate renal impairment subgroup. FPG is a continuous measure, the change from baseline for each participant is calculated at the Week 52 value minus the baseline value.

  • Absolute Change From Baseline in Fasting Plasma Glucose (FPG) to Week 52 - Severe Renal Impairment Subgroup [ Time Frame: Baseline, Week 52 ] [ Designated as safety issue: No ]
    Adjusted* mean change from baseline in fasting plasma glucose (FPG) achieved with saxagliptin 2.5 mg once daily versus placebo at Week 52 (Full Analysis Set) for the severe renal impairment subgroup. FPG is a continuous measure, the change from baseline for each participant is calculated at the Week 52 value minus the baseline value.

  • Absolute Change From Baseline in Fasting Plasma Glucose (FPG) to Week 52 - End-Stage Renal Impairment Subgroup [ Time Frame: Baseline, Week 52 ] [ Designated as safety issue: No ]
    Adjusted* mean change from baseline in fasting plasma glucose (FPG) achieved with saxagliptin 2.5 mg once daily versus placebo at Week 52 (Full Analysis Set) for the end-stage renal impairment subgroup. FPG is a continuous measure, the change from baseline for each participant is calculated at the Week 52 value minus the baseline value.

  • Absolute Change From Baseline in Fasting Plasma Glucose (FPG) to Week 52 - Moderate Renal Impairment Subgroup [ Time Frame: Baseline, Week 52 ] [ Designated as safety issue: No ]
    Adjusted* mean change from baseline in fasting plasma glucose (FPG) achieved with saxagliptin 2.5 mg once daily versus placebo at Week 52 (Full Analysis Set) for the moderate renal impairment subgroup. FPG is a continuous measure, the change from baseline for each participant is calculated at the Week 52 value minus the baseline value
