Arm | Intervention/treatment |
---|---|
Experimental: Empagliflozin 10 mg
Patients with evidence of chronic kidney disease (CKD) at risk of kidney disease progression, with or without diagnosed diabetes mellitus administered orally once daily 10 milligram (mg) film-coated tablets of empagliflozin.

Drug: Empagliflozin
Taken daily with or without food |
Placebo Comparator: Placebo
Patients with evidence of chronic kidney disease (CKD) at risk of kidney disease progression, with or without diagnosed diabetes mellitus administered orally once daily film-coated tablets of placebo to match empagliflozin.

- Interventional Part: Time to First Occurrence of Kidney Disease Progression or Cardiovascular Death ('as Adjudicated') [ Time Frame: Follow-up period: From the day of randomisation to the day of the final follow-up visit, up to 1136 days. ]
Incidence rate of first occurrence of kidney disease progression (KDP) or adjudicated cardiovascular death is reported in the Outcome Measure Data Table. Metrics such as the median time-to-event (TTE) was not estimable due to insufficient events being experienced.
Incidence rate= (Number of patients who experienced the event of first occurrence of KDP or cardiovascular death)*100/(patient years at risk (pt-yrs at risk). pt-yrs at risk= sum of time at risk [days] over all patients in a treatment group / 365.25.
Kidney disease progression was defined as:
- end stage kidney disease (defined as the initiation of maintenance dialysis or receipt of a kidney transplant) OR
- a sustained decline in estimated glomerular filtration rate (eGFR) to <10 mL/min/1.73m^2 OR
- renal death OR
- a sustained decline of ≥40% in eGFR from randomisation.
- Key Secondary Endpoint: Interventional Part - Time to First Hospitalization for Heart Failure ('as Adjudicated') or Cardiovascular Death ('as Adjudicated') [ Time Frame: Follow-up period: From the day of randomisation to the day of the final follow-up visit, up to 1140 days. ]
Incidence rate of first hospitalization for heart failure or cardiovascular death is reported in the Outcome Measure Data Table because metrics such as the median time-to-event (TTE) not estimable due to insufficient events being experienced.
Incidence rate= (Number of patients who experienced the event of first hospitalization for heart failure or cardiovascular death) *100/(patient years at risk (pt-yrs at risk)).
pt-yrs at risk= sum of time at risk [days] over all patients in a treatment group / 365.25.
- Key Secondary Endpoint: Interventional Part - Time to Occurrences of All-cause Hospitalizations (First and Recurrent Combined) [ Time Frame: Follow-up period: From the day of randomisation to the day of the final follow-up visit, up to 1140 days. ]Total number of all-cause hospitalizations (first and recurrent combined) is reported in the Outcome Measure Data Table. Conventional time-to-event (TTE) metrics such as the median not calculable for a recurrent TTE analysis.
- Key Secondary Endpoint: Interventional Part - Time to Death From Any Cause ('as Adjudicated') [ Time Frame: Follow-up period: From the day of randomisation to the day of the final follow-up visit, up to 1140 days. ]
Incidence rate of death from any cause is reported in the Outcome Measure Data Table. Metrics such as the median time-to-event (TTE) not estimable due to insufficient events being experienced.
Incidence rate of death from any cause = (Number of patients who experienced the event of death from any cause) * 100/(patient years at risk (pt-yrs at risk)). pt-yrs at risk= sum of time at risk [days] over all patients in a treatment group / 365.25.
- Interventional Part: Time to First Occurrence of Kidney Disease Progression [ Time Frame: Follow-up period: From the day of randomisation to the day of the final follow-up visit, up to 1136 days. ]
Incidence rate of first occurrence of kidney disease progression is reported in the Outcome Measure Data Table. Metrics such as the median time-to-event (TTE) not estimable due to insufficient events being experienced.

- Interventional Part: Time to Cardiovascular Death ('as Adjudicated') [ Time Frame: Follow-up period: From the day of randomisation to the day of the final follow-up visit, up to 1140 days. ]
Incidence rate of first occurrence of kidney disease progression is reported in the Outcome Measure Data Table. Metrics such as the median time-to-event (TTE) not estimable due to insufficient events being experienced.
Incidence rate of cardiovascular death is reported in the Outcome Measure Data Table. Metrics such as the median time-to-event (TTE) not estimable due to too few events being experienced.
Incidence rate of cardiovascular death= (Number of patients who experienced the event of cardiovascular death) *100/(patient years at risk (pt-yrs at risk)). pt-yrs at risk= sum of time at risk [days] over all patients in a treatment group / 365.25.
- Interventional Part: Time to First Occurrence Cardiovascular Death ('as Adjudicated') or End Stage Kidney Disease (ESKD) [ Time Frame: Follow-up period: From the day of randomisation to the day of the final follow-up visit, up to 1140 days. ]
Incidence rate of first occurrence of cardiovascular death or end stage kidney disease (ESKD) is reported in the Outcome Measure Data Table. Metrics such as the median time-to-event (TTE) not estimable due to insufficient events being experienced.
Incidence rate of first occurrence cardiovascular death or end stage kidney disease (ESKD)= (Number of patients who experienced the event of first occurrence of cardiovascular death or end stage kidney disease (ESKD)) *100/(patient years at risk (pt-yrs at risk)). pt-yrs at risk= sum of time at risk [days] over all patients in a treatment group / 365.25.
ESKD was defined as the initiation of maintenance dialysis or receipt of a kidney transplant.
