Other Events.

On May 14, 2024, Pliant Therapeutics, Inc. (the “Company”) announced topline data from a 12-week, randomized, double-blind, placebo-controlled trial of bexotegrast (PLN-74809) conducted at Massachusetts General Hospital evaluating change in total collagen levels in the lungs of patients with idiopathic pulmonary fibrosis (“IPF”). IPF is a disease characterized by excessive collagen deposition in the lung. Bexotegrast-treated patients showed reduced total lung collagen post treatment as measured by positron emission tomography (“PET”) imaging, compared to increased total lung collagen in the placebo group, suggesting potential reversal of fibrosis. Bexotegrast-treated patients demonstrated improvements in forced vital capacity and reduction in cough severity across all timepoints compared to placebo. Bexotegrast 160 mg was well tolerated over 12 weeks with no drug-related serious adverse events and no discontinuations. A copy of the Company’s press release, titled “Pliant Therapeutics Announces Positive Topline Data from a Phase 2a Collagen PET Imaging Clinical Trial of Bexotegrast in Patients with Idiopathic Pulmonary Fibrosis,” is attached as Exhibit 99.1 to this Current Report and is incorporated by reference herein.
