Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome will be determined by the annual rate of change in eGFR (mL/min/1.73 m2) from the initiation of ipragliflozin in the ipragliflozin group compared to those during 24 months equivalent to the period in the control group. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary outcome will be determined by the composite end point of a sustained reduction in eGFR of > 50 %, or severe impairment of kidney function which was defined as an eGFR <30 mL/min/1.73 m2 (i.e. CKD stage G4 and G5), or doubling time of urinary albumin (protein) per creatine. | — |
