Single-cell Profiling Demonstrates the Antifibrotic Effects of Bexotegrast on Pathologic Lung Cell Populations in the Presence and Absence of Background Therapy (ATS 2025) - "CONCLUSION Treatment of fibrotic human PCLS with bexotegrast or nintedanib showed distinct cell-specific pharmacodynamic profiles, with bexotegrast found to significantly reduce TGF-β-regulated gene expression (e.g. COL1A1) in αVβ6 and αVβ1-expressing pathologic lung cell populations. These findings demonstrate the potential for bexotegrast to provide antifibrotic benefit alone or in combination with currently approved treatments for IPF."

Characterizing the Antifibrotic Activity of Bexotegrast on Distinct Fibroblast Populations in PCLS From Multiple ILD Subtypes (ATS 2025) - "In PCLS from fibrotic non-IPF ILD explants, inhibition of integrins αVβ6 and αVβ1 with bexotegrast reduced fibrogenic gene expression across multiple fibroblast subpopulations. These data are consistent with our previous observations in IPF explants and support further investigation of the antifibrotic activity of bexotegrast in ILD-associated progressive pulmonary fibrosis. 1Tsukui, T. et al."

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."

Single-Cell Profiling Demonstrates the Antifibrotic Effects of Bexotegrast on Pathologic Lung Cell Populations in the Presence and Absence of Background Therapy (GlobeNewswire) - "Pliant Therapeutics presents...data at the American Thoracic Society International Conference....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."

Pliant Therapeutics Announces Strategic Realignment of Workforce and Operations (GlobeNewswire) - "The restructuring aims to minimize costs and preserve cash reserves as the Company awaits topline data from the BEACON-IPF Phase 2b/3 trial of bexotegrast in patients with idiopathic pulmonary fibrosis (IPF). Pliant expects topline data from the BEACON-IPF trial to be available in the second quarter of 2025. Once available, the Company will evaluate the final dataset and determine next steps for bexotegrast’s development."

A Comparative Study With ING-006, Nintedanib, Nerandomilast and Bexotegrast Using the In Vivo CAM-Patient-Derived IPF Model (ATS 2025) - "ING-006 also demonstrates superior inhibitory activity over fezagepras (formerly PBI-4050) in ZQ-16 stimulated-pErK lung fibroblasts as well as through inhibition of fibrotic gene expression. CAM-IPF is an efficient method to predict antifibrotic activity. Among other compounds currently used or under investigation for IPF treatment, ING-006 shows superior antifibrotic activity in fibroblasts and lung tissue xenografts from IPF patients, making it a promising candidate for IPF treatment."

Bexotegrast in people with idiopathic pulmonary fibrosis (IPF): a plain language summary of publication of the INTEGRIS-IPF study. (PubMed, Ther Adv Respir Dis) - "There is no cure for IPF, treatment includes symptom management and consideration for the use of nintedanib or pirfenidone, which may decrease the pace of disease progression.The study compared bexotegrast to a placebo (a treatment that looks identical to the medicine but has no medicinal effect) to look at how well it works and how safe it is in treating people with IPF. Most people in the study also took one of two medicines that are already approved by the FDA for IPF, pirfenidone or nintedanib."
