Study Endpoints

Primary Endpoints

Percent Change from Baseline in Noncalcified Plaque (NCP) Volume
Baseline, Week 104
Time to First Occurrence of Any Component of the Major Adverse Cardiac Event (MACE)-4 Composite Endpoint
Baseline up to End of Study (About 4.5 Years)

Time to first event in a MACE-4 composite endpoint, comprised of cardiovascular death, nonfatal myocardial infarction, nonfatal ischemic stroke, and urgent coronary revascularization.

Percent Change From Baseline in Time Averaged Lipoprotein(a) [Lp(a)] Over Days 60-180
Baseline, Days 60 - 180

LPa levels were assessed using Immuno turbidimetric method. Percent change is calculated as: Percent Change=\[(Lp(a) at Time Point-Lp(a) at Baseline)/Lp(a) at Baseline\]×100 Least squares (LS) mean was determined using mixed model repeated measures (MMRM) model with log(Lp(a)) - log(Baseline) = log(Baseline) + Treatment + Time + Treatment\*Time (Type III sum of squares) as post-baseline measures. Result presented is after back-transformation. Variance-Covariance structure = Unstructured. Analyses included all participants having non-missing baseline and at least one non-missing post-baseline value of the response variable.

Secondary Endpoints

Percent Change from Baseline in Mean Fat Attenuation Index (FAI) Score
Baseline, Week 104
Percent Change from Baseline in Lp(a) Level
Baseline through Week 104
Percentage of Participants Reporting Strongly Agree or Agree on the Subcutaneous Administration Assessment Questionnaire (SQAAQ) Version 3.0 Items

Frequently asked questions about Lepodisiran

What is lepodisiran used for?

Lepodisiran is an investigational RNA therapy being studied in adults with elevated lipoprotein(a) who have atherosclerotic cardiovascular disease or are at high risk of cardiovascular events. It is designed to lower Lp(a) levels and reduce the risk of major adverse cardiovascular events such as heart attack and stroke.

How does lepodisiran work?

Lepodisiran is a small interfering RNA (siRNA) therapy. It targets the production of lipoprotein(a) by interfering with RNA to reduce the synthesis of apolipoprotein(a), a key component of Lp(a) particles. This mechanism aims to lower circulating Lp(a) levels, which are a known risk factor for cardiovascular disease.

Who is developing lepodisiran?

Lepodisiran is being developed by Eli Lilly and Company (ticker: LLY). The company is conducting Phase 3 clinical trials to evaluate its safety and efficacy in reducing cardiovascular events in patients with elevated Lp(a).

What phase is lepodisiran in?

Lepodisiran is in Phase 3 clinical development. It is not yet approved by the FDA or any regulatory agency. The ongoing Phase 3 program includes a large cardiovascular outcomes trial and a separate trial assessing plaque reduction in coronary arteries.

What clinical trials is lepodisiran in?

Lepodisiran is being evaluated in two Phase 3 trials: NCT06292013, known as ACCLAIM-Lp(a), which is assessing the reduction of major adverse cardiovascular events in 17,300 adults with elevated Lp(a) and ASCVD, and NCT07613294, which is studying whether lepodisiran can reduce coronary artery plaque in adults with elevated Lp(a) who have had heart events or are at high risk.

Is lepodisiran the same as lepodisiran sodium?

Yes, lepodisiran sodium is the salt form of lepodisiran and is often used interchangeably. Both names refer to the same investigational siRNA therapy developed by Eli Lilly and Company for lowering lipoprotein(a) and reducing cardiovascular risk.
