Arm | Intervention/treatment |
---|---|
Experimental: Inclisiran
Inclisiran sodium 300 milligrams (mg) (equivalent to 284 mg inclisiran) in 1.5 milliliters (mL) will be administered as a SC injection on Day 1, Day 90, and then every 6 months.
|
Drug: Inclisiran Sodium
Inclisiran is a small interfering ribonucleic acid (RNA) that inhibits PCSK9 synthesis. |
Placebo Comparator: Saline Solution
Placebo (1.5 mL) will be administered as a SC injection of saline solution on Day 1, Day 90, and then every 6 months.
|
Drug: Placebo
Placebo will be supplied as sterile normal saline (0.9% sodium chloride in water for injection).

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
Participants may be included if they meet all of the following inclusion criteria prior to randomization:
- Male or female participants ≥18 years of age.
- History of ASCVD (coronary heart disease [CHD], cardiovascular disease [CVD], or peripheral arterial disease [PAD]).
- Serum LDL-C ≥1.8 millimole (mmol)/liter (L) (≥70 mg/dL).
- Fasting triglyceride <4.52 mmol/L (<400 mg/dL) at screening.
- Calculated glomerular filtration rate >30 mL/min by estimated glomerular filtration rate (eGFR) using standardized clinical methodology
- Participants on statins should be receiving a maximally tolerated dose.
- Participants not receiving statins must have documented evidence of intolerance to all doses of at least 2 different statins.
- Subjects on lipid-lower therapies (such as a statin and/or ezetimibe) should be on a stable dose for ≥30 days before screening with no planned medication or dose change during study participation.
- Subjects were willing and able to give informed consent before initiation of any study-related procedures and willing to comply with all required study procedures
Exclusion Criteria:
Participants will be excluded from the study if any of the following exclusion criteria apply prior to randomization:
- New York Heart Association (NYHA) class IV heart failure.
- Uncontrolled cardiac arrhythmia.
- Uncontrolled severe hypertension.
- Active liver disease.
-
Females who are pregnant or nursing, or who are of childbearing potential and unwilling to use at least 2 methods of highly effective contraception (failure rate less than 1% per year) (for example, combined oral contraceptives, barrier methods, approved contraceptive implant, long-term injectable contraception, or intrauterine device) for the entire duration of the study. Exemptions from this criterion:
- Women >2 years postmenopausal (defined as 1 year or longer since last menstrual period) and more than 55 years of age.
- Postmenopausal women (as defined above) and less than 55 years of age with a negative pregnancy test within 24 hours of randomization.
- Women who are surgically sterilized at least 3 months prior to enrollment.
- Males who are unwilling to use an acceptable method of birth control during the entire study period (such as condom with spermicide).
- Treatment with other investigational products or devices within 30 days or 5 half-lives of the screening visit, whichever is longer.
- Treatment (within 90 days of screening) with monoclonal antibodies directed towards PCSK9.
