Building a pipeline with innovative medicines at the core

We work hard to lower LDL-C by discovering and developing innovative and combination medicines. 

Cardiovascular Outcomes Trial

Our global cardiovascular outcomes trial (CVOT), called CLEAR Outcomes, is a first-of-its-kind, landmark CVOT in patients with statin intolerance and is on track to conclude in the second half of 2022.

CLEAR Outcomes is a Phase 3, event-driven, randomized, multicenter, double-blind, placebo-controlled trial designed to evaluate whether treatment with bempedoic acid reduces the risk of cardiovascular events. The primary endpoint of the study is the effect of bempedoic acid on four-component major adverse cardiovascular events (MACE). The study enrolled more than 14,000 patients at over 1,400 sites in 32 countries.1-3

What is CLEAR Outcomes?

Cholesterol Lowering via Bempedoic acid, an ACL-Inhibiting Regimen (CLEAR) Outcomes is a randomized, double-blind, placebo-controlled clinical trial, looking at the effects of bempedoic acid on cardiovascular events for patients with documented statin intolerance and high risk of cardiovascular disease.

CLEAR Outcomes trial facts

  • Completed enrollment in August 2019
  • 1,400 sites in 32 countries
  • Largest trial in Esperion’s history

Patient population:

  • Established atherosclerotic cardiovascular disease or diabetes with additional risk factors
  • Documented statin intolerance
  • 47.9% women, 52.1% men
  • Mean age: 65.5±9.0 years

Primary endpoint

  • Time to four-component major adverse cardiovascular events (MACEs), including cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, or coronary revascularization

Oral PCSK9 inhibitor

All available PCSK9 treatment options are delivered by injection, but four out of five patients prefer a pill.4 That’s why Esperion is in the investigational stage of developing a small molecule PCSK9 inhibitor that can be taken as a tablet.

PCSK9 (proprotein convertase subtilisin/kexin type 9) is an enzyme responsible for regulating low-density lipoprotein (LDL) receptors. PCSK9 inhibitors stop LDL receptors from being broken down, increasing the number of LDL receptors present to remove cholesterol from the blood. Current approved PCSK9 inhibitors are delivered as injections. A tablet, oral PCSK9 inhibitor would fill a key gap in non-statin treatment options for certain patients.

PCSK9 is a validated target for the treatment of dyslipidemia and reduction of cardiovascular risk.
