Pliant Therapeutics Provides Corporate Update and Reports Second Quarter 2026 Financial Results
FORTIFY, a Phase 1b indication expansion trial of PLN-101095,
experiencing strong enrollment
Appointed seasoned oncology drug development leaders
Flavia Borellini, Ph.D. and Robert Iannone, M.D., M.S.C.E. to Board of Directors
SOUTH SAN FRANCISCO, CA., August 11, 2026 - 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 second quarter 2026 financial results.
“In the second quarter, we continued to execute across the portfolio, led by strong enrollment in FORTIFY,” said Bernard Coulie, M.D., Ph.D., President and Chief Executive Officer of Pliant. “With the appointments of Flavia and Robert to the board, Pliant now has deep global oncology drug development and commercialization expertise at this important time for our oncology program. We continue to make progress on our proprietary integrin-targeted drug-delivery platform and look forward to sharing more information on the platform soon.”
Oncology Program
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. Pliant is currently conducting FORTIFY, a Phase 1a/1b open-label, dose-escalation and indication expansion trial (NCT0670706), to evaluate the safety, tolerability, pharmacokinetics, and preliminary evidence of antitumor activity of PLN-101095, in combination with pembrolizumab, in patients with immune checkpoint inhibitor (ICI)-refractory advanced or metastatic solid tumors.
•Enrollment continues in FORTIFY, a Phase 1b indication expansion trial. FORTIFY will enroll up to 102 patients across three cohorts including non-small cell lung cancer (NSCLC), clear cell renal cell carcinoma (ccRCC) and tumors with high tumor mutational burden. Patients are treated for 14 days with PLN-101095 dosed at 1,000 mg twice daily as monotherapy, after which pembrolizumab is added as combination therapy. Enrollment remains strong, progressing ahead of schedule. Interim data is expected in 2027.
•Oral presentation at AACR of updated PLN-101095 Phase 1 data highlights monotherapy biomarker data showing a coordinated T-cell reactivation cascade in responders. In July, at the American Association for Cancer Research’s (AACR) Drug Discovery and Development conference, the Company reviewed encouraging PLN-101095 Phase 1 monotherapy biomarker data. As previously reported, all responding patients showed large increases in plasma interferon gamma (IFN-γ), a modulator of anti-tumor immunity, after 14 days of monotherapy with PLN-101095. Updated data show that blocking of αvβ8 by PLN-101095 also resulted in increases in CXCL9, a recruiter of T cells, and granzyme-B, a marker for cytotoxic arming in responding patients. Increased IFN-γ, CXCL9 and granzyme-B after PLN-101095 monotherapy signals a shift in the tumor microenvironment that could potentially resensitize tumors to pembrolizumab. Importantly, no non-responders experienced increases in these biomarkers.
Integrin-Targeted Delivery Platform
•Utilizing cell-specific integrin receptors, Pliant has developed a platform to deliver drug payloads, including siRNAs, to selective tissue types. Current programs are focused on delivering siRNAs to skeletal muscle cells and other tissues. Preclinical proof-of-concept studies are currently ongoing. The Company believes this integrin-targeting drug-delivery platform has the potential for broad applicability across multiple disease areas utilizing a variety of drug payloads. Pliant plans to provide additional detail on the platform and path forward, including initial treatment indications, in the second half of 2026.
Corporate Highlights
•Appointed Flavia Borellini, Ph.D. and Robert Iannone, M.D., M.S.C.E. to the Company’s Board of Directors. Dr. Borellini brings more than 25 years of executive management experience in the biopharmaceutical industry with a focus on the global development of targeted oncology drugs from preclinical to commercial stage. Dr. Iannone, who currently serves as Executive Vice President, Research and Development and Chief Medical Officer at Jazz Pharmaceuticals, brings more than two decades of executive drug development and regulatory leadership, including the approval of several targeted and immuno-oncology medicines.
Second Quarter 2026 Financial Results
•Research and development expenses were $16.7 million, as compared to $32.2 million for the prior-year quarter. The decrease was primarily due to completing close-out activities for BEACON-IPF, a Phase 2b/3 study of bexotegrast, in 2025 and reduced personnel-related expenses, including stock based compensation, driven by decreased headcount compared to prior year.
•General and administrative expenses were $7.1 million, as compared to $13.4 million for the prior-year quarter. The decrease was primarily due to personnel-related expenses, including stock-based compensation, driven by decreased headcount compared to prior year.
•Net loss was $22.4 million as compared to $43.3 million for the prior-year quarter. The decrease was primarily due to significantly lower operating expenses following the termination of bexotegrast development in IPF in 2025 and decreased personnel-related expenses, including stock-based compensation, driven by reduced headcount compared to prior year.
•As of June 30, 2026, the Company had cash, cash equivalents and short-term investments of $159.6 million which the Company expects to be sufficient to fund operations into the second half of 2028.
