ClinConnect Summary

This clinical trial is studying a medicine called inclisiran to see if it is safe and helpful for people who have just had a serious heart problem known as acute coronary syndrome (ACS). ACS includes conditions like heart attacks, and this study looks at starting inclisiran treatment early, while patients are still in the hospital, alongside their usual heart treatments. Researchers want to find out if inclisiran can better lower “bad” cholesterol (LDL cholesterol) and improve heart health compared to a placebo, which is a treatment with no active medicine.

People who might join the study are adults who have been hospitalized for ACS and have had certain heart procedures if needed. They should have higher levels of LDL cholesterol despite being on cholesterol-lowering medicines or not having taken these medicines before. To join, participants need to be stable in the hospital and able to safely receive the treatment within seven days of their heart event. During the study, participants will receive either inclisiran or a placebo, in addition to their usual care, and their health will be monitored. This trial is not yet recruiting, so if you or a loved one fits these criteria, it’s something to watch for in the future.

Eligibility criteria

• Inclusion Criteria:
• Participant eligible for inclusion in this study must meet all the following criteria:
• At Screening:
• • 1. Signed informed consent must be obtained prior to participation in the study.
• • 2. Males and females, ≥18 years of age at the time of providing written informed consent.
• • 3. Ability to understand study's requirements and provide informed consent and comply with all required study procedures.
• • 4. Hospitalization for a ACS event (STEMI or NSTEMI).
• • 5. Receiving treatment for the qualifying ACS event, according to clinical judgement, by means of medical treatment alone or percutaneous coronary revascularization.
• • 6. Had a successful PCI (with or without stent) for the qualifying event if a PCI was required.
• 7. LDL-C value at the Screening visit measured by the local lab of:
• • LDL-C ≥70 mg/dL in participant previously treated with high-intensity statin (atorvastatin ≥40 mg/day or rosuvastatin ≥20 mg/day) or equivalent as per national guidelines and local regulation for at least 4 weeks before screening or
• • LDL-C ≥100 mg/dL in participant previously treated with low/moderate-intensity statin for at least 4 weeks before screening or
• • LDL-C ≥125 mg/dL in participant previously not treated with statins for at least 4 weeks before screening, or who never received statins (including statin intolerant participants).
• At Randomization:
• • 8. The participant must have a Baseline fasting LDL-C ≥70 mg/dL (local lab assessment) to be eligible for randomization.
• • 9. Randomization within 7 days (≤ 7 days) following hospital admission for the qualifying ACS event and before/at discharge.
• Exclusion Criteria:
• • Participant meeting any of the following criteria is not eligible for inclusion in this study.
• • Only for Japan: For exclusion criteria 6, investigator judgment should be documented in the source data document.
• 1. Participant who is clinically unstable during hospitalization for the qualifying ACS event, defined by any of the following events within 24 hours prior to randomization:
• • Hemodynamic instability: hypotension, defined as sustained systolic blood pressure of \<90 mmHg due to cardiac failure with associated symptoms requiring inotropes
• • Arrhythmic events: Ventricular storm (e.g., torsade, ventricular tachycardia, ventricular flutter)
• • Cardiogenic shock or mechanical complication of myocardial infarction
• • New York Heart Association (NYHA) class IV heart failure
• • Left ventricular ejection fraction \<20% at randomization (after all treatment procedures, based on the latest assessment of the LVEF using invasive or non-invasive assessment modalities)
• • Uncontrolled severe hypertension: systolic blood pressure \>180 mmHg or diastolic blood pressure \>110 mmHg prior to randomization despite antihypertensive therapy.
• • 2. Participant who has undergone or is scheduled to undergo CABG for treatment of the qualifying ACS event.
• • 3. Active liver disease defined as: (i) any known current infectious, neoplastic, or metabolic pathology of the liver or (ii) alanine aminotransferase (ALT) elevation \>3x ULN or aspartate aminotransferase (AST) elevation \>3x ULN, or total bilirubin elevation \>2x ULN (except participant with Gilbert's syndrome) at the Screening visit, in the context of an ACS, and assessed as related to the index event and/or treatment procedures (such as PCI). Eligibility will be based on Investigator's judgement for participant who will be randomized.
• • 4. Renal insufficiency (eGFR \<30 mL/min/1.73m2) at the Screening visit.
• • 5. Fasting triglycerides value \>400 mg/dL (4.52 mmol/L; assessed by local labs) at randomization visit.
• • 6. Participant, who based on the Investigator's judgement, could reach the LDL-C target value of \<55 mg/dL after 4 weeks on statin treatment only.
• • 7. Secondary hypercholesterolemia (based on medical history).
• • 8. Homozygous familial hypercholesterolemia (based on medical history).
• • 9. Participant on apheresis at the Screening visit.
• • 10. Ongoing or medical history of myopathy at the Screening visit.
• • 11. CK values ≥5x ULN at Screening visit and confirmed by repeat test during Screening (local lab) , in the context of an ACS, and assessed as related to the index event and/or treatment procedures (such as PCI) eligibility will be based on Investigator's judgement for participant who will be randomized (who will be switched to or initiated on the protocol-specified dose of high-intensity statin of atorvastatin ≥40 mg QD or rosuvastatin ≥20 mg QD). Unless a more stringent CK value threshold is mandated by a local regulatory authority (e.g., ≥3x ULN in Korea according to MFDS internal guideline).
