HPS-4/TIMI 65/ORION-4: A Double-blind Randomized Placebo-controlled Trial Assessing the Effects of Inclisiran on Clinical Outcomes Among People With Atherosclerotic Cardiovascular Disease

The HPS-4/TIMI 65/ORION-4 study aims to provide evidence about both the efficacy and safety of inclisiran. It is intended to be conducted at approximately 150 clinical sites in Europe (primarily in the UK) and North America. Approximately 15,000 participants aged 55 years or older with pre-existing atherosclerotic cardiovascular disease will be randomized between inclisiran sodium 300 mg and matching placebo (given by subcutaneous injection on the day of randomization, at 3 months and then every 6-months) in a 1:1 ratio for a planned median duration of about 5 years. Consistent with relevant guideline recommendations for people with vascular disease, it is intended that participants be on intensive background LDL-lowering therapy (for example, atorvastatin 40 or 80 mg daily, simvastatin 40 or 80 mg daily, or rosuvastatin 20 or 40 mg daily) at screening. In order to achieve a target LDL cholesterol reduction of at least 1.2 mmol/l [45 mg/dL], it is intended to recruit a study population with a mean LDL cholesterol of at least 2.6 mmol/l [100mg/dL] at baseline.
