Esperion Next-Generation ACLY Inhibitor Development Pipeline

The Esperion next-generation ACLY inhibitor discovery program is a world-class approach

ACLY Inhibitor Discovery Program Objectives

  • Use leading edge approaches and technology to identify/design differentiated new chemical entities
  • Improve potency and selectivity several orders of magnitude vs. current active site inhibitors
  • Target several cell types important in disease pathogenesis
  • Identify potential indications and patient populations using leading edge bioinformatic approaches
ACLY Molecule

ACLY is the key enzyme in the non-canonical TCA cycle, an energy nexus in all cells1,2

Canonical TCA Cycle

The canonical TCA cycle, also known as the Krebs Cycle, is primarily a catabolic pathway that consumes lipids and carbohydrates to generate ATP for energy production and occurs in mitochondria.1

Non-Canonical TCA Cycle

The non-canonical TCA cycle is primary an anabolic path-way that supports cell states with high demands due to accelerated proliferation and/or effector functions; is utilized by highly proliferative cells, cancer cells, and stem cells; and occurs in mitochondria, cytoplasm, and nucleus.1,2

Energetic/Metabolic Processes Regulated by Acetyl CoA Production

Allosteric ACLY inhibition is a novel approach to targeting this key enzyme

Active site ACLY inhibitor

Active site ACLY inhibitors prevent the substrate (coenzyme A) from binding, thus inhibiting enzyme activity

Allosteric ACLY Inhibitor

Allosteric ACLY inhibitors bind allosteric sites distant from the active site which changes the conformation of the active site, thus inhibiting enzyme activity.

PSC Staging and Progression6

PSC Staging and Progression

PSC is a Rare Disease With Increasing Prevalence7

 Estimated 6-16 cases per 100,000 in North America and Western Europe: ~46,000 patients diagnosed with PSC across United States, ~30,000 patients diagnosed with PSC across Europe

±This data was calculated using previously-published epidemiological data from multiple sources. Inter-regional variability results in differing estimates among European regions.

Disproportionately affects men compared to women (60-70%)
Peak incidence of PSC is 25 to 45 years of age
