Pliant Therapeutics is a public, clinical stage biopharmaceutical company focused on the discovery and development of novel therapies for fibrotic diseases. Founded by Third Rock Ventures with world-renowned academic thought leaders, Pliant is raising the bar to meet the unmet medical needs of physicians, patients and families impacted by fibrotic disease. The Company’s focus is on mechanism-based intervention in the fibrotic process using small molecules.

The Company’s lead product candidate, PLN-74809, is an oral, small molecule selective inhibitor of the αvβ1 and αvβ6 integrins that play a key role in multiple fibrotic pathways. PLN-74809 has received Orphan Drug Designation from the U.S. Food and Drug Administration in both idiopathic pulmonary fibrosis (IPF) and primary sclerosing cholangitis (PSC) and are currently in Phase 2a clinical trials for these indications. The company recently reported positive data from its Phase 2a trial in IPF and is currently ramping up activities in preparation for a late-stage clinical trial at worldwide sites.

Pliant has also developed PLN-1474, a small molecule, selective inhibitor of αvß1 for the treatment of nonalcoholic steatohepatitis, or NASH with liver fibrosis. Pliant is initiating 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.

The Company is seeking passionate, creative, and dedicated individuals to join our team and contribute to our mission.
