Linagliptin as Add on Therapy to Empagliflozin 10 mg or 25 mg With Background Metformin in Patient With Type 2 Diabetes

Overview

The objective of the study is to investigate the efficacy, safety and tolerability of linagliptin 5 mg qd compared to placebo given for 24 weeks in inadequately controlled T2DM patients on empagliflozin 10 mg or 25 mg and maximum tolerated dose of metformin. The primary objective of efficacy evaluation is planned after 24 weeks of treatment. The study is designed to show superiority of the combination of empagliflozin and linagliptin over empagliflozin alone.

Clinical Trial Outcome Measures

Primary Measures

  • Change From Baseline of HbA1c After 24 Weeks of Treatment.
    • Time Frame: Baseline and 24 weeks
    • Change from baseline in Glycated haemoglobin (HbA1c) [%] after 24 weeks of treatment with double-blind trial medication, i.e. HbA1c change from baseline at Week 24. The term “baseline” was not used to refer to measurements prior to the administration of open-label medication. Such measurements were referred to as “pre-treatment”. Analyses of change from pre-treatment used the last value before first administration of open-label medication as point of reference. Observed Case (OC): This method analyse only available data that were observed while patients were on treatment, i.e., excluding the missing data. All values measured after rescue medication taken were set to missing. Full Analysis Set (FAS): Includes all patients in the Treated set who had a baseline HbA1c assessment and at least 1 on-treatment HbA1c assessment during the double-blind part of the trial.

Secondary Measures

  • Fasting Plasma Glucose (FPG) Change From Baseline at 24 Weeks.
    • Time Frame: Baseline and 24 weeks
    • Change from baseline FPG (mmol/L) after 24 weeks of treatment with double-blind trial medication, i.e. FPG change from baseline at Week 24.
