Cardiorenal evidence review: CKD progression and cardiovascular outcomes
Nonsteroidal mineralocorticoid receptor antagonist · Evidence Stability Review
CKD associated with Type 2 Diabetes
Supportable for current intended use, subject to existing caveats.
Sourced from FDA labels, pivotal trial publications, and two major guideline bodies. Two phase 3 trials (n=13,026 pooled) with consistent kidney and cardiovascular composite outcomes. Guideline recommendations strengthened from suggested to recommended (Level A) over the observation window.

Type 2 Diabetes / Obesity
Evidence movement warrants active review before the statement is relied on.
The same molecule is now being promoted in a broader population than the pivotal trials primarily studied. The move from high-risk diabetic or cardiovascular settings to general weight-management settings changes the strength of the supporting evidence and the review action.
