Pliant Therapeutics Announces The Company Led Oral And Poster Presentations Of Clinical And Preclinical Data This Week As Part Of the American Thoracic Society 2025 International Conference

Pliant Therapeutics, Inc. (NASDAQ:PLRX) today announced that the Company led oral and poster presentations of clinical and preclinical data this week as part of the American Thoracic Society (ATS) 2025 International Conference, held from May 16-21, 2025.

Characterizing the Antifibrotic Activity of Bexotegrast on Distinct Fibroblast Populations in PCLS from Multiple ILD Subtypes

In a featured oral presentation, Johanna Schaub, Ph.D., Director of Translational Sciences at Pliant Therapeutics, discussed an evaluation of the antifibrotic activity of bexotegrast in fibrotic human precision-cut lung slices (PCLS) generated from non-idiopathic pulmonary fibrosis (IPF) interstitial lung disease (ILD) patient lung explants. Results showed that bexotegrast, a dual inhibitor of αVβ6/αVβ1 integrins, reduced expression of genes related to TGF-β signaling and fibrogenesis in alveolar type 1 (AT1) cells and multiple fibroblast subpopulations.

Plasma Proteome Analysis Reveals Shared and Unique Biomarkers of ILD Subtypes

In a poster presentation, Erine Budi, Ph.D., Senior Scientist II Translational Biology at Pliant Therapeutics, reviewed a comparative analysis assessing circulating plasma biomarkers of ILD in healthy subjects and patients with idiopathic pulmonary fibrosis (IPF), rheumatoid arthritis-ILD (RA-ILD), and scleroderma associated-ILD (SSc-ILD). Results identified biomarkers consistently dysregulated across multiple ILD subtypes that could assist in informing clinical decision making in ILD.

Single-Cell Profiling Demonstrates the Antifibrotic Effects of Bexotegrast on Pathologic Lung Cell Populations in the Presence and Absence of Background Therapy

In a poster presentation, Mahru An, Ph.D., Director of Translational Sciences at Pliant Therapeutics, reviewed a single-nuclei RNAseq analysis of fibrotic human precision-cut lung slices comparing the pharmacodynamic effects of bexotegrast, a dual inhibitor of αVβ6 and αVβ1 integrins, alone, or in combination with nintedanib. Results showed that treatment with bexotegrast or nintedanib displayed distinct cell-specific pharmacodynamic profiles. In addition, bexotegrast alone, or in the presence of nintedanib, significantly reduced the expression of type I collagen and other profibrotic genes in aberrant basaloid cells (αVβ6-expressing) and fibroblasts (αVβ1-expressing), while treatment with nintedanib alone did not.
