Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: •To evaluate the effect of corticosteroids combined with RASBs in IgAN patients with active renal lesions (ACIgAN) versus RASBs alone to determine whether the renal damage is reversed by corticosteroids; •To evaluate the effect of SGLT2i (Dapagliflozin) combined with RASBs versus RASBs alone in patients with chronic renal lesions (CHRONIgAN) and in patients with moderate renal lesions at high or very high risk of CKD to determine whether a delay of the ESKD onset is achieved.;Secondary Objective: •after the prediction of ESKD through our IgAN CDSS tool (DialCheck), to determine whether personalized therapy delays the impairment of the renal function; •a cutting edge-molecular study will be conducted on a small cohort of enrolled IgAN patients with active or chronic/moderate renal lesions to evaluate the effect of precision therapy (BIO-D).;Primary end point(s): Between-arms difference in proteinuria reduction within 6 months in ACIgAN and within 12 months in CHRONIgAN study.;Timepoint(s) of evaluation of this end point: 6 months in ACIgAN study and 12 months in CHRONIgAN study. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • eGFR slope calculated as mean of individual slope obtained from individual linear regression of eGFR overtime (3 years); • eGFR decline > 40 % from the baseline value; • composite end point: GFR decline > 40%, ESKD (defined as long-term GFR = 15 ml/min/1.73m2 for more than three months or need for maintenance dialysis or kidney transplantation) or death due to kidney disease; • absolute difference between last GFR value and baseline GFR; • stable renal function defined as a decline in GFR = 5 ml/min/1.73m2 at the end of three years follow- up; • mean annual change in the slope of the reciprocal of serum creatinine concentration; • time-averaged proteinuria (TA-P) calculated as the weighted mean of all post- randomisation measurement, with weights representing the time elapsed since the previous measurement; • proteinuria slope, calculated as a mean of individual slope, obtained from individual linear regression of daily proteinuria overtime (3 years); • complete remission of proteinuria defined as achievement of urinary protein level = 0.2 g/day or a urinary protein-to-creatinine ratio = 0.2 g/g; • partial remission of proteinuria defined as achievement of a urinary protein level = 50% or greater compared with the baseline value.;Timepoint(s) of evaluation of this end point: 3 years | — |
