Can a monthly shot slow stiff heart valves? new trial aims to find out.
NCT ID NCT05646381
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a monthly injection called pelacarsen to see if it can slow the worsening of calcific aortic valve stenosis, a condition where the heart valve becomes stiff and narrow. About 502 adults aged 50-79 with high levels of lipoprotein(a) and mild-to-moderate valve disease will receive either the drug or a placebo for 3 years. The main goal is to measure changes in blood flow through the valve and calcium buildup using heart scans.
