Silence Therapeutics Reports Promising Phase 1 Data for Divesiran in Polycythemia Vera at EHA 2025

Silence Therapeutics presented updated Phase 1 data for divesiran at EHA 2025, showing the siRNA therapy essentially eliminated the need for phlebotomies in 21 polycythemia vera patients with a combined history of 79 prior phlebotomies.

Eli Lilly's Lepodisiran Shows 95% Reduction in Lipoprotein(a), Offering New Hope for South Asian Heart Patients

Eli Lilly's experimental drug lepodisiran demonstrated up to 95% reduction in lipoprotein(a) levels with a single 400mg dose in midstage trials, potentially addressing a significant cardiovascular risk factor prevalent in South Asian populations.

Silence Therapeutics Halts Phase III Development of Zerlasiran, Seeks Partnership for Cardiovascular Drug

Silence Therapeutics has paused the Phase III development of zerlasiran, its RNA-silencing therapy for cardiovascular diseases, until securing a strategic partnership, extending their cash runway into 2027.

Zerlasiran Shows Durable Lp(a) Reduction in ALPACAR-360 Trial

Zerlasiran, a gene-silencing therapy, demonstrated sustained reductions in lipoprotein(a) [Lp(a)] levels through 60 weeks in the ALPACAR-360 trial.

Zerlasiran Shows Significant Lipoprotein(a) Reduction in Phase 2 Trial

Zerlasiran, a novel siRNA, significantly reduced time-averaged lipoprotein(a) levels by over 80% in a Phase 2 trial, offering a potential treatment for elevated Lp(a).

Zerlasiran Demonstrates Significant Lipoprotein(a) Reduction in Phase II Trial

Zerlasiran, a GalNAc-conjugated siRNA, significantly reduced lipoprotein(a) levels by 80-85% in patients at high risk of atherosclerotic cardiovascular disease.

Zerlasiran Shows Promise in Phase II Trial for Elevated Lipoprotein(a)

Zerlasiran, a GalNAc-conjugated siRNA, significantly reduced lipoprotein(a) levels in patients at high risk of atherosclerotic cardiovascular disease.

Lilly's Muvalaplin and Silence's Zerlasiran Show Promise in Lowering Lipoprotein(a) in Phase II Trials

Eli Lilly's oral drug muvalaplin reduced lipoprotein(a) levels by up to 86% in adults with cardiovascular risk factors, meeting its primary endpoint.

Zerlasiran Shows Cumulative Lp(a) Reduction in Phase 2 Trial

Zerlasiran, a small interfering RNA (siRNA), significantly reduced lipoprotein(a) [Lp(a)] levels in a Phase 2 trial, showing over 80% reduction over 36 weeks.

Lp(a)-Lowering Therapies Show Promise in Phase II Trials

• Zerlasiran, a siRNA therapy, demonstrated an 85% reduction in Lp(a) levels over 36 weeks in the ALPACAR-360 trial, showing promise for ASCVD patients. • Muvalaplin, an oral agent, reduced Lp(a) by up to 85% in the KRAKEN trial, offering a potential alternative to injectable therapies for high Lp(a). • Both therapies were well-tolerated in phase II studies, with no significant safety concerns, marking a step forward in addressing unmet needs for Lp(a) lowering. • Clinical trials for both drugs are ongoing, with results expected in 2025 and 2026, which will determine whether lowering Lp(a) reduces cardiovascular events.
