28

Primary endpoint: • Percentage change in LDL-C from baseline to Day 510

Day 540. This is the average percentage change in LDL-C from baseline over

the period between Day 90 and Day 540

Key secondary endpoints: • Absolute change in LDL-C from baseline to Day 510

• Time adjusted absolute change in LDL-C from baseline between Day 90 and

Day 540

• Percentage change from baseline to Day 510 in PCSK9, total cholesterol, ApoB,

• The study will randomize ≥15,000 participants aged ≥55 years with pre-existing cardiovascular disease between inclisiran sodium 300 mg and matching placebo for a median of about 5 years.

Randomization Visit

ORION-4Long term cardiovascular outcomes study

Clinical & regulatorystrategy

Primary endpoint:

Composite of major adverse cardiovascular events (MACE), defined as:Coronary (CHD) death;Myocardial infarction;Fatal or non-fatal ischaemic stroke; orUrgent coronary revascularization procedure

Secondary endpoints:

Composite outcome of CHD death or myocardial infarctionCardiovascular death

Inhibition of PCSK9 with Inclisiran is a very promising, and potentially the simplest and most effective, approach to further reducing LDL-C, the cause of atherosclerosis• LDL-C variability within individuals is practically eliminated• Injection burden reduced substantially• Sustained effect between infrequent injections• Opportunity to improve patient adherence

Phase II and the ongoing phase III studies have shown robust long term efficacy with no safety issues

Conclusions

PCSK9 Inhibitor therapy with Inclisiran
