Announcement
Silence Therapeutics today presented end-of-treatment data from its Phase 2 ALPACAR-360 study of zerlasiran, a short interfering RNA (siRNA), in atherosclerotic cardiovascular disease (ASCVD) patients with high lipoprotein(a) [Lp(a)] levels (≥125 nmol/L).
AI Summary
Silence Therapeutics presented end-of-treatment data today from its Phase 2 ALPACAR-360 study of zerlasiran, a short interfering RNA (siRNA) aimed at patients with atherosclerotic cardiovascular disease (ASCVD) who have high lipoprotein(a) levels (≥125 nmol/L). The study is the first to report time-averaged Lp(a) reductions that measure the treatment’s impact over longer periods, including the time between doses.
The results showed that different dosing regimens of zerlasiran (300 mg every 16 weeks, 300 mg every 24 weeks, or 450 mg every 24 weeks) led to more than 80% mean placebo-adjusted reduction in Lp(a) levels over 36 weeks, with maximum reductions exceeding 90%. Notably, these reductions persisted until the final visit 60 weeks after the first dose, and the treatment was well tolerated. These promising results will help guide the dosing strategy for upcoming Phase 3 trials.
