Outcome results
HbA1c Change From Baseline in Patients With Mild or Moderate Renal Impairment
Change from baseline in HbA1c after 24 weeks, for patients with mild or moderate renal impairment. Note adjusted means are provided.
Time frame: Baseline and 24 weeks
Population: Full analysis set (FAS) which included all randomised patients, treated with at least one dose of trial medication, who had a baseline HbA1c value. Values after start of antidiabetic rescue therapy were set to missing and last observation carried forward (LOCF) was used for imputation of missing values.
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| Placebo | HbA1c Change From Baseline in Patients With Mild or Moderate Renal Impairment | 0.05 percentage of HbA1c | Standard Error 0.04 |
| Empa 25mg | HbA1c Change From Baseline in Patients With Mild or Moderate Renal Impairment | -0.46 percentage of HbA1c | Standard Error 0.04 |

Hypoglycaemic Events
Percentage of patients who experienced a hypoglycaemic event. A hypoglycaemic event was regarded as confirmed if it was documented as an adverse event with plasma glucose values \<= 70 mg/dL (\<=3.9mmol/L) measured or with a documentation that the assistance of another person to actively administer carbohydrate, glucagon or other resuscitative action had been required.
Time frame: From first drug administration until 7 days after last trial medication intake, up to 458 days
Population: Treated set which included all patients treated with at least one dose of randomised trial medication.
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Placebo | Hypoglycaemic Events | 27.6 percentage of participants |
| Empa 25mg | Hypoglycaemic Events | 26.5 percentage of participants |
| Empa 25mg | Hypoglycaemic Events | 27.4 percentage of participants |
