INTEGRIS-PSC featured in an oral late breaker presentation

SOUTH SAN FRANCISCO, Calif., Nov. 18, 2024 (GLOBE NEWSWIRE) -- Pliant Therapeutics, Inc. (Nasdaq: PLRX), a late-stage biotechnology company and leader in the discovery and development of novel therapeutics for the treatment of fibrotic diseases, today announced the presentation of clinical data at The Liver Meeting^® 2024 of the American Association for the Study of Liver Diseases (AASLD) being held in San Diego, California.

Bexotegrast, an oral inhibitor of αvβ6 and αvβ1 integrins, was shown to improve markers and symptoms of cholestasis and stabilized markers of liver fibrosis in participants with primary sclerosing cholangitis: Week 24 results from the Phase 2 INTEGRIS-PSC trial

In an oral late breaker presentation, Kris Kowdley, M.D., Director, Liver Institute Northwest and Professor of Medicine, Elson S. Floyd College of Medicine at Washington State University, reviewed the positive data from the INTEGRIS-PSC trial that demonstrated bexotegrast was well tolerated across all doses tested and displayed antifibrotic and anti-cholestatic activity across multiple measures in patients with primary sclerosing cholangitis (PSC). Improvements included improvements in liver stiffness, Enhanced Liver Fibrosis (ELF) scores, as well as liver biochemistry and magnetic resonance imaging (MRI).

Identification of novel inflammatory serum and urinary protein biomarkers for PSC

In a poster presentation, Johanna Schaub, Ph.D., Principal Scientist II, Translational Sciences at Pliant Therapeutics, presented a study that combined two unique proteomic screening approaches to identify novel diagnostic biomarkers in patients with PSC. Results showed the discovery of dozens of putative serum and urine biomarker candidates along with previously described biomarkers, validating this approach. In addition, this approach yielded proteins previously proposed to predict progression in primary biliary cholangitis and cirrhosis, suggesting a role in predicting progression in PSC.

The posters presented at AASLD will be made available on the Publications page of the Pliant website, www.PliantRx.com, at the time of presentation.
