Key points
  • The growing field of research aimed at the particle took a hit earlier this year when top-line results showed an experimental drug reduced Lp(a) but failed to lower serious outcomes.
  • In the Phase 3 trial, the drug pelacarsen dramatically lowered Lp(a), a mashup of lipids and proteins that at high levels can heighten the risk of severe heart problems.

But despite lower Lp(a), the HORIZON trial showed no difference in heart attacks, strokes, urgent coronary revascularization, or deaths in participants followed for almost five years who were randomly selected to take the drug or a placebo.
