SOUTH SAN FRANCISCO, Calif., Nov. 06, 2025 (GLOBE NEWSWIRE) -- Pliant Therapeutics, Inc. (Nasdaq: PLRX), a clinical-stage biotechnology company focused on the discovery and development of integrin-based therapeutics, today provided a corporate update and reported third quarter 2025 financial results.

“During the third quarter, our team continued to advance our portfolio while winding down activities surrounding the BEACON-IPF trial,” said Bernard Coulie, M.D., Ph.D., President and Chief Executive Officer of Pliant. “Looking ahead, we continue to evaluate a range of opportunities to create shareholder value.”

Third Quarter and Recent Developments

Oncology Program

• Phase 1 open-label trial of PLN-101095 in solid tumors has completed enrollment. PLN-101095 is an oral, small molecule, dual selective inhibitor of αvβ8 and αvβ1 integrins designed to overcome checkpoint resistance by blocking TGF-β activation in the tumor microenvironment. The Phase 1 open-label, dose-escalation trial of PLN-101095 as monotherapy and in combination with pembrolizumab is in patients with solid tumors that are resistant to immune checkpoint inhibitors. In March of 2025 we announced interim data from this trial showing PLN-101095 was well tolerated and displayed an objective response rate of 50% in the third of five ascending dose cohorts. The trial has now completed enrollment of all five dose cohorts. Data from the trial, including the two highest dose cohorts, is expected by the end of 2025.

Bexotegrast

• BEACON-IPF close out activities to be completed in fourth quarter. Close out activities from the BEACON-IPF Phase 2b/3 clinical trial are expected to be completed in the fourth quarter of 2025 with full results from the trial to be submitted for future publication.

Corporate Highlights

• In October, the Company announced that it completed a voluntary prepayment of all outstanding principal, accrued and unpaid interest, fees, costs and expenses under the March 11, 2024 Loan Agreement with Oxford Finance LLC.

Third Quarter 2025 Financial Results

• Research and development expenses were $17.9 million as compared to $47.8 million for the prior-year quarter. The decrease was primarily driven by the discontinuation of BEACON-IPF.
• General and administrative expenses were $10.3 million as compared to $14.3 million for the prior-year quarter. The decrease was primarily due to lower personnel-related costs resulting from the strategic restructuring of our workforce.
• Net loss was $26.3 million as compared to $57.8 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 September 30, 2025, the Company had cash, cash equivalents and short-term investments of $243.3 million.
