研究概览
简要总结
This was a placebo-controlled, double-blind, randomized trial in Japanese participants with history of coronary artery disease (CAD) or participants categorized in 'high risk' by JAS 2017 guideline, or Japanese participants with heterozygous familial hypercholesterolemia (HeFH) and elevated Low-density lipoprotein cholesterol (LDL-C) despite maximum tolerated dose of statin(s) to evaluate the efficacy, safety, tolerability, and PK of subcutaneous inclisiran injection(s).
详细描述
The expected duration of the participants' involvement in the study was approximately 374 days which included screening (up to 14 days), Day 1 study drug administration, two additional injections on Day 90 and Day 270, and the follow-up period to Day 360.
The primary analysis was conducted after all participants had finished Day 180 visit assessments or discontinued before Day 180 visit.
After the primary analysis, double-blind treatment period were maintained to Day 360, although specific sponsor members (except for blinded monitors) were unblinded for the regulatory submission in Japan.

入选标准
- •Participants with history of CAD or participants categorized in 'high risk' by Japan Atherosclerosis Society (JAS) 2017 guidelines or participants with heterozygous familial hypercholesterolemia (HeFH)
- •As per the JAS 2017 guideline, participants not meeting the LDL-C management targets.
- •Participants on statins should be receiving a maximally tolerated dose.
- •Participants not receiving statins must have documented evidence of intolerance to at least one statin.
- •The lipid-lowering therapy should have remained stable for ≥ 30 days before screening with no planned medication/ dose change until Day 180
排除标准
- •Participants diagnosed with homozygous familial hypercholesterolemia (HoFH).
- •Treatment (within 90 days of screening) with monoclonal antibodies directed towards PCSK
- •New York Heart Association (NYHA) class IV heart failure or last known left ventricular ejection fraction <25%.
- •Cardiac arrhythmia within 3 months prior to randomization that is not controlled by medication or via ablation.
- •Uncontrolled hypertension: systolic blood pressure >160 mmHg or diastolic blood pressure >100 mmHg prior to randomization despite antihypertensive therapy.
- •Active liver disease defined as any known current infectious, neoplastic, or metabolic pathology of the liver or unexplained elevations in alanine aminotransferase (ALT), aspartate aminotransferase (AST), >3x the upper limit of normal (ULN), or total bilirubin >2x ULN at screening.
- •Severe concomitant non-cardiovascular disease that carries the risk of reducing life expectancy to less than 2 years.

结局指标
主要结局
Percent Change From Baseline in Low-density Lipoprotein Cholesterol (LDL-C) to Day 180
时间窗: Baseline, Day 180
Percent change from baseline in LDL-C was calculated to evaluate the effect of inclisiran at Day 180. Difference between different inclisiran dose groups and the placebo group in percentage change in LDL-C levels from baseline to Day 180 were calculated to capture both, the effect of the study drug and the effect of additional medications, mirroring the conditions in clinical practice. An MMRM (Mixed-effect Model with Repeated Measurement) was used as the primary analysis model, with treatment group, visits, interaction between visits and treatment groups, current use of statins or other lipid-modifying therapies as fixed effects, and baseline LDL-C as a continuous covariate.
