Company Overview

About Pliant Therapeutics

Pliant Therapeutics develops small molecule integrin inhibitors targeting the pathological tissue scarring (fibrosis) that drives diseases including idiopathic pulmonary fibrosis (IPF), primary sclerosing cholangitis (PSC), and nonalcoholic steatohepatitis (NASH/MASH). Integrins are cell surface receptors that activate TGF-β, the master regulator of fibrosis — blocking specific integrin subtypes (αvβ6, αvβ1) can halt or reverse fibrosis progression without broadly suppressing immunity.

Business Model & Competitive Advantage

Pliant's lead asset bexotegrast (PLN-74809) is a dual αvβ6/αvβ1 inhibitor advancing in Phase 2b/3 trials for IPF — a fatal lung scarring disease with median survival of 3–5 years after diagnosis. IPF affects 100,000+ U.S. patients with two approved therapies that only slow progression. Bexotegrast's Phase 2 data showed lung function stabilization and biomarker improvements that have sustained investor and partner interest.

Competitive Landscape 2025–2026

Listed on Nasdaq since 2019, Pliant has established itself as the leading pure-play integrin inhibitor company for fibrosis. The company's pipeline extends to liver fibrosis (PSC, MASH) and kidney fibrosis, targeting markets where no approved anti-fibrotic therapies exist and where integrin biology is well-validated by genetics and preclinical models.
