The pre-specified statistical analysis was not conducted, because data are too sparse in the subgroup of hyperfilterers. |

Recruitment details
A randomized, double-blinded, placebo-controlled, crossover trial to compare the effect of empagliflozin versus placebo when added to ramipril on reducing glomerular hyperfiltration in patients with type 1 Diabetes mellitus (T1D), Type 2 Diabetes (T2D), or obesity.
Pre-assignment details
Participants who successfully completed the 4 weeks open-label ramipril run-in period and meet all of the inclusion, and non of the exclusion criteria were randomized into the trial, with no stratification to one of two sequences.
Participants by arm
| Arm | Count |
|---|---|
| Sequence A: 25 mg Empagliflozin / Placebo During dosing Period 1, participants were administered 1 tablet of 25 milligram (mg) empagliflozin once daily as single oral dose for 4 weeks added to open-label Ramipril, where participants had been dose escalated from 1.25, 5, 7.5, or 10 mg, up to 10 mg ramipril or to their maximum tolerated dose. This was followed by a 4-week wash-out period with background treatment of open-label ramipril administered orally as capsule once or twice daily as prescribed by the investigator,and then followed by 4 weeks of dosing period 2 of 1 tablet matching placebo administered once daily as single oral dose added to open-label Ramipril. | 16 |
| Sequence B: Placebo / 25 mg Empagliflozin During dosing Period 1, participants were administered 1 tablet of matching placebo once daily as single oral dose for 4 weeks added to open-label Ramipril, where participants had been dose escalated from 1.25, 5, 7.5, or 10 mg, up to 10 mg ramipril or to their maximum tolerated dose. This was followed by a 4-week wash-out period with background treatment of open-label ramipril administered orally as capsule once or twice daily as prescribed by the investigator,and then followed by 4 weeks of dosing period 2 of 1 tablet of 25 mg empagliflozin administered once daily as single oral dose added to open-label Ramipril. | 14 |

Outcome results
Glomerular Filtration Rate (GFR) Under Euglycaemic Conditions After 4 Weeks of Treatment With Either Empagliflozin Added to Ramipril or Placebo Added to Ramipril.
Glomerular filtration rate (GFR) under euglycaemic conditions after 4 weeks of treatment with either empagliflozin added to ramipril or placebo added to ramipril. The pre-specified statistical analysis was not conducted, because data are too sparse in the subgroup of hyperfilterers.
Time frame: At week 4 and at week 12
Population: Hyperfilterers: Patients before ramipril monotherapy with GFR ≥ 135 mL/min/1.73m², as measured at screening (visit 4).

Filtration Status (Glomerular Filtration Rate (GFR) < 120 mL/Min/1.73m², Yes/no) After 4 Weeks of Treatment With Either Empagliflozin Added to Ramipril or Placebo Added to Ramipril
Filtration status (Glomerular Filtration Rate (GFR) \< 120 mL/min/1.73m²) after 4 weeks of treatment with either empagliflozin added to ramipril or placebo added to ramipril. Filtration status is defined as whether a patient has normal Filtration status (GFR \< mL/min/1.73m², yes) or not (GFR ≥ mL/min/1.73m², no). The pre-specified statistical analysis was not conducted, because data are too sparse in the subgroup of hyperfilterers.
Time frame: At week 4 and at week 12.
Population: Hyperfilterers: Patients before ramipril monotherapy with GFR ≥ 135 mL/min/1.73m², as measured at screening (visit 4).
