Integrating liver endpoints in clinical trials of cardiovascular and kidney disease

A Publisher Correction to this article was published on 12 June 2025

This article has been updated

Abstract

The intersection of cardiovascular disease, metabolic disorders and chronic kidney disease represents a complex clinical picture challenging healthcare systems worldwide. Metabolic-dysfunction-associated steatotic liver disease (MASLD) often manifests sequentially or concomitantly with these diseases, and may share underlying mechanisms and risk factors. Growing evidence suggests that new therapies could have benefits across these diseases, but trial sponsors and investigators tend to be reluctant to include patients with comorbidities—particularly liver diseases—in clinical trials. In this Perspective, we call for inclusion of patients with MASLD and measurement of liver outcomes in cardio–kidney–metabolic trials, when data suggest mechanistically plausible benefits and liver and cardiovascular safety. We discuss the implications of this new paradigm for clinical trial design and considerations for regulatory approval. Finally, we outline the challenges to implementing such an approach and provide recommendations for future clinical trial conduct.
