Inclisiran for Subjects With ASCVD or ASCVD-Risk Equivalents and Elevated Low-density Lipoprotein Cholesterol

This is a Phase III, placebo-controlled, double-blind, randomized study in participants with ASCVD or ASCVD-Risk equivalents and elevated LDL-C despite maximum tolerated dose of LDL-C lowering therapies to evaluate the efficacy, safety, and tolerability of subcutaneous (SC) inclisiran injection(s). The study will be an international multicenter study (non-United States).

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.

The above information is not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.
