Kylo-11 treatment for people with atherosclerotic cardiovascular disease and high Lp(a)

A Double-blind, Randomized, Placebo-controlled Phase 2 Study to Evaluate Efficacy and Safety of Kylo-11 in Participants With Atherosclerotic Cardiovascular Disease and Elevated Lipoprotein(a)

Phase 2 Interventional Kylonova (Xiamen) Biopharma co., LTD. · NCT07327840

This phase 2, randomized, double-blind test will try subcutaneous Kylo-11 versus placebo in adults with ASCVD and elevated Lp(a) to see if it lowers Lp(a) and is safe.

What this trial studies

This is a multicenter, double-blind, randomized, placebo-controlled, dose-finding phase 2 trial of subcutaneous Kylo-11 in adults with established atherosclerotic cardiovascular disease and elevated Lp(a). Participants are randomized to Kylo-11 or matched placebo and followed for safety and lipid biomarker responses, including changes in Lp(a). Key exclusions include moderate-to-severe heart failure (NYHA III–IV or LVEF <30%), uncontrolled hypertension or arrhythmias, and recent malignancy. The sponsor is Kylonova (Xiamen) Biopharma and enrollment occurs at several sites in China, including major cardiac centers in Beijing and Baotou.

Who should consider this trial

Good fit: Adults aged 18–80 with established atherosclerotic cardiovascular disease and elevated Lp(a) who meet the full protocol criteria are the intended participants.

Not a fit: People with NYHA class III–IV heart failure, LVEF below 30%, uncontrolled blood pressure or arrhythmias, or recent malignancy are unlikely to be eligible and may not benefit from participation.

Why it matters

Potential benefit: If successful, Kylo-11 could substantially lower Lp(a) and potentially reduce future cardiovascular risk in people with ASCVD and high Lp(a).

How similar studies have performed: Other targeted Lp(a) therapies, including antisense and siRNA agents, have shown substantial Lp(a) reductions in clinical trials, so this approach has precedent.
