Pliant Therapeutics is a late-stage biopharmaceutical company focused on the discovery and development of novel therapies for fibrotic diseases.

The Company’s lead product candidate, bexotegrast (PLN-74809), is an oral small molecule, selective inhibitor of the αvβ1 and αvβ6 integrins that play a key role in multiple fibrotic pathways. Bexotegrast has received Fast Track Designation and Orphan Drug Designation from the U.S. Food and Drug Administration for both idiopathic pulmonary fibrosis (IPF) and primary sclerosing cholangitis (PSC) and Orphan Drug Designation from the European Medicines Agency in IPF and PSC. Pliant is currently conducting BEACON-IPF, a Phase 2b/3 trial of bexotegrast for the treatment of IPF and INTEGRIS-PSC, a Phase 2a trial of bexotegrast for the treatment of PSC.

Pliant is conducting a Phase 1 study for its third clinical program, PLN-101095, a small molecule, dual-selective inhibitor of αvß8 and αvß1 integrins, that is being developed for the treatment of solid tumors. The Company also has discovery and development programs in oncology and muscular dystrophies.
