SOUTH SAN FRANCISCO, Calif., Aug. 07, 2025 (GLOBE NEWSWIRE) -- Pliant Therapeutics, Inc. (Nasdaq: PLRX), a clinical-stage biotechnology company and leader in integrin-based drug development, today provided a corporate update and reported second quarter 2025 financial results.

“While our activities in the quarter focused on the closure of BEACON-IPF and workforce realignment, we also took actions to ensure that we maintain core capabilities in support of Pliant’s next steps,” said Bernard Coulie, M.D., Ph.D., President and Chief Executive Officer of Pliant. “At the center is a deeply experienced late-stage clinical and regulatory development organization positioned to execute advanced trials. We remain committed to delivering shareholder value and look forward to providing updates in the future.”

Second Quarter and Recent Developments

Bexotegrast

• Bexotegrast development in idiopathic pulmonary fibrosis (IPF) discontinued. Following an analysis of the full safety and efficacy data from the BEACON-IPF Phase 2b/3 clinical trial, the Company has discontinued development of bexotegrast in idiopathic pulmonary fibrosis (IPF). While bexotegrast-treated patients demonstrated early signs of efficacy, the drug was shown to have an unfavorable risk-benefit profile based on IPF-related adverse events. Full results from BEACON-IPF will be submitted for future publication.

Oncology Program

• Phase 1 trial of PLN-101095 in solid tumors continues to enroll. PLN-101095 is an oral, small molecule, dual selective inhibitor of αvβ8 and αvβ1 integrins designed to block TGF-β activation in the tumor microenvironment. The Phase 1 open-label, dose-escalation trial of PLN-101095 trial as monotherapy and in combination with pembrolizumab is in patients with solid tumors that are resistant to immune checkpoint inhibitors. The trial is currently dosing the fifth of five planned dose cohorts, evaluating PLN-101095 at 2000 mg administered twice daily (BID). Initial data from the two highest dose cohorts of the trial is expected by the end of 2025.

Corporate Highlights

• In May, the Company announced a strategic restructuring of its workforce and other cost-saving measures intended to extend its cash runway. By the end of the second quarter, the restructuring was largely complete.

Second Quarter 2025 Financial Results

• Research and development expenses were $32.2 million as compared to $45.6 million for the prior-year quarter. The decrease was primarily driven by the discontinuation of BEACON-IPF.
• General and administrative expenses were $13.4 million as compared to $15.0 million for the prior-year quarter. The decrease was primarily due to personnel-related costs resulting from the strategic restructuring of our workforce.
• Net loss was $43.3 million as compared to $55.9 million for the prior-year quarter. The decrease was primarily attributable to the discontinuation of BEACON-IPF coupled with the decrease in personnel-related costs resulting from the strategic restructuring of our workforce.
• As of June 30, 2025, the Company had cash, cash equivalents and short-term investments of $264.4 million.
