Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. The difference in the change in urine albumin-to-creatinine ratio (UACR), based on the average of two morning spot urine samples, between the two groups, measured from baseline to the end of both intervention periods (Intervention period I: semaglutide vs. control, followed by Intervention period II: additional finerenone for all participants).

Secondary endpoints 3

  1. Change in urine albumin-to-creatinine ratio from baseline to end of both intervention periods.
  2. Change in urine albumin-to-creatinine ratio from baseline to 20 weeks semaglutide treatment.
  3. Change in urine albumin-to-creatinine ratio from baseline to end of combination therapy (semaglutide followed by additional finerenone), compared to the change during semaglutide treatment alone.
