About EpiEndo Pharmaceuticals (

EpiEndo is a clinical-stage biopharmaceutical company with a unique approach to inflammatory disorders that focuses on the enhancement of epithelial barrier integrity to reduce disease-causing inflammation.

Epithelial cells are a key part of the barrier that makes up human lung tissue and other organs such as the gut and skin. A breakdown of this barrier is implicated in several chronic inflammatory diseases.

EpiEndo’s new class of orally available macrolide, with reduced antimicrobial resistance (AMR) effect, known as a ‘Barriolide’, shows promise as a first-in-class therapeutic for chronic respiratory diseases as well as other inflammatory indications. EpiEndo’s lead asset, EP395, is the first Barriolide™ to enter into Phase 2 clinical trials, for chronic obstructive pulmonary disease (COPD).

EP395, aims to be the first on-market oral, barrier-enhancing and anti-inflammatory drug, which has the potential to be a unique and impactful treatment option for COPD patients. According to the WHO, COPD is the third leading cause of death globally, and the global economic burden of COPD projected to cost $4.8 trillion by 2030.
