|Condition or disease||Intervention/treatment||Phase|
|Atherosclerotic Cardiovascular Disease||Drug: Inclisiran Drug: Placebo||Phase 3|
The ORION-4 study aims to provide evidence about both the efficacy and safety of inclisiran. Inclisiran is a PCKS9 synthesis inhibitor which has been found to reduce LDL-cholesterol by about 50-60%. ORION-4 will investigate the effects of inclisiran on major adverse cardiovascular events.
The study is intended to be conducted at approximately 150 clinical sites in the UK and the USA. 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.

Inclisiran sodium 300 milligrams (mg) will be administered as a SC injection at randomization, 3 months and then every 6 months.
Inclisiran is a small interfering ribonucleic acid (RNA) that inhibits PCSK9 synthesis.
Placebo Comparator: Placebo
Placebo will be administered as SC injections of saline solution at randomization, 3 months and then every 6 months.
Placebo will be supplied as sterile normal saline (0.9% sodium chloride in water for injection).
Other Name: Saline solution
