The objectives detailed in the Core Protocol apply to this DSA. In addition, the MRA DSA has a domain-specific secondary objective to determine the effect of the interventions on the time to the composite of ≥57% eGFR decline or kidney failure.
Inclusion criteria
Potential participants must satisfy all of the inclusion criteria in the Core Protocol, and also satisfy the following:
Urine albumin-creatinine ratio (uACR) >200 mg/g or urine protein-creatinine ratio (uPCR) >300 mg/g from the most recent result in the previous 3 months.
On a stable standard of care treatment for CKD, including a SGLT2i unless there is a documented reason not to be using a SGLT2i, for 4 weeks before screening according to treating physician.
Treating physician believes finerenone is clinically appropriate for the participant.
Participant and treating physician are willing and able to perform MRA DSA procedures.

DSA-Specific outcome measure
The outcomes detailed in the Core Protocol apply to this DSA. In addition, the MRA DSA has a domain-specific secondary outcome of time to the composite of ≥57% eGFR decline or kidney failure.
