Efficacy and Safety of Inclisiran as Monotherapy in Patients With Primary Hypercholesterolemia Not Receiving Lipid-lowering Therapy.

A Double-blind, Randomized, Placebo- and Active-Comparator Controlled Study to Evaluate the Efficacy of Inclisiran as Monotherapy in Patients With Primary Hypercholesterolemia Not Receiving Lipid-Lowering Therapy (VictORION-Mono)

CKJX839D12304 was a research study to determine if the study treatment, called inclisiran, in comparison to placebo and ezetimibe effectively reduces Low-Density Lipoprotein Cholesterol (LDL-C) as measured by percentage change from baseline to Day 150. This study was conducted in eligible participants with primary hypercholesterolemia not receiving any lipid-lowering therapy (LLT), with a 10-year Atherosclerotic Cardiovascular Disease (ASCVD) risk of less than 7.5%.

This study was a randomized, double-blind, placebo- and active comparator-controlled, multicenter study in 350 adult participants with primary hypercholesterolemia not receiving any LLT with a 10-year ASCVD risk score of less than 7.5%. This study evaluated the efficacy and safety of inclisiran sodium 300 mg, administered as a monotherapy in comparison to ezetimibe and placebo.

The study consisted of:

• a screening period of up to 14 days;
• a double-blind treatment period of 150+/- 5 days during which participants were randomly assigned to either the inclisiran arm, the ezetimibe arm or the placebo arm in a 2:1:1 ratio; and
• a safety follow-up / End of Study visit conducted 30+5 days after the Day 150 visit.

The overall study duration was approximately 190 days.

Inclusion Criteria at screening:

• informed consent signed prior to participation in study
• fasting LDL-C of >= 100 mg/dL but < 190 mg/dL
• fasting triglycerides <= 400 mg/dL
• 10-year ASCVD risk score < 7.5%
• not on any lipid-lowering therapy within 90 days of screening

Key Exclusion Criteria:

• history of ASCVD
• diabetes mellitus or fasting plasma glucose of >= 7.0 mmol/L or HbA1c >= 6.5%
• secondary hypercholesterolemia, e.g. hypothyroidism (TSH above upper limit of normal)
