Meril Presents Successful LANDMARK RCT One-Year Results
Meril Life Sciences announced one-year results from its pivotal LANDMARK trial, presented during the prestigious Late-Breaking Trial session at EuroPCR 2025, one of the world’s premier cardiology conferences held annually in Paris, France. The LANDMARK trial is the first randomized non-inferiority trial comparing the balloon-expandable Myval THV series with other contemporary balloon-expandable Sapien THV series and self-expandable Evolut THV series in patients with symptomatic severe aortic stenosis. The Myval THV series demonstrated non-inferiority to contemporary THVs in terms of 1-year clinical efficacy composite endpoint (Myval THV Series: 13% vs. Contemporary THV: 13.1%, difference: -0.1%, one-sided 95% CI: 3.9%, Pnoninferiority < 0.0001). Additionally, in the composite endpoint of clinical efficacy combined with QoL, outcomes were comparable (Myval THV Series: 19.5% vs. Contemporary THVs: 22.7%, difference: -3.2%, 95% CI: -9.2 to 2.9, P=0.33). Hemodynamic parameters including effective orifice area (EOA), mean pressure gradient (PG), and incidence of moderate or greater aortic regurgitation…
