SNF472: mechanism of action and results from clinical trials

Purpose of review Vascular calcification (VC) is associated with increased cardiovascular event rates, particularly in patients with end-stage kidney disease (ESKD). Dysregulated mineral metabolism and inflammation have been shown to promote VC, however, treatment options targeting VC specifically are not available. This review outlines the pathophysiological mechanisms contributing to VC in ESKD and describes recent studies evaluating the effects of the first-in-class inhibitor of VC, SNF472. Recent findings SNF472 directly inhibits calcium phosphate crystal formation and aggregation. SNF472 has completed early phase clinical trials with a favourable safety profile and Phase 2 clinical trial data have shown attenuation of coronary artery and aortic valve calcification in patients receiving hemodialysis. Summary Therapeutic agents that directly target VC may prevent the multiple complications associated with dystrophic calcification in patients with ESKD.
