Advancing a potentially best-in-class once-daily oral, locally-activated PDE4 inhibitor prodrug specifically engineered for the treatment of inflammatory bowel disease (IBD)

Enrollment of first patient for Phase 2 ASCENTRA-UC trial of PALI-2108 expected in the second half of 2026; primary efficacy results expected in the second half of 2027

IND for Phase 2 ASCENTRA-CD trial of PALI-2108 for the treatment of Crohn’s disease expected in the second half of 2026

Strong balance sheet expected to support execution through key Phase 2 clinical readouts

Denver, CO, Aug. 10, 2026 (GLOBE NEWSWIRE) -- Palisade Bio, Inc. (NASDAQ:PALI) ("Palisade Bio" or the "Company"), a clinical-stage biopharmaceutical company developing next-generation prodrugs for patients living with inflammatory and fibrotic diseases, today reported financial results for the second quarter ended June 30, 2026, and provided a business update. During the quarter, the Company completed key regulatory and operational activities supporting the planned commencement of the Phase 2 ASCENTRA-UC trial of PALI-2108 in the second half of 2026.

Palisade Bio is advancing PALI-2108 into Phase 2 development for ulcerative colitis (UC) and Crohn’s disease (CD), supported by encouraging results from its completed Phase 1 clinical trial.

Key Takeaways from the Phase 1 Clinical Trial

Across the Phase 1 clinical trial, PALI-2108 demonstrated favorable safety and tolerability, sustained exposure of the active metabolite above the IC90 threshold, targeted distribution in the ileum and colon, and pharmacodynamic (PD) activity across key inflammatory and fibrotic pathways.
The Phase 1 clinical trial included five patients with UC and five patients with fibrostenotic Crohn’s disease (FSCD).
In the UC cohort, 5 out of 5 patients achieved clinical response and 2 out of 5 achieved clinical remission based on Modified Mayo Score.
In the FSCD cohort, PALI-2108 reduced mean SES-CD score by approximately 47.5% (a 3.8-point improvement), with 2 out of 5 patients achieving both endoscopic response and remission based on SES-CD.

Together, these findings provide a strong foundation for the planned commencement of the Phase 2 ASCENTRA-UC trial in the second half of 2026. The Company also intends to submit an investigational new drug (IND) application to the U.S. Food and Drug Administration (FDA) for the Phase 2 ASCENTRA-CD trial of PALI-2108 in the second half of 2026.

"The second quarter marked a decisive transition for Palisade Bio as we completed the regulatory and operational work required to advance PALI-2108 into Phase 2 development," said JD Finley, Chief Executive Officer of Palisade Bio. "With FDA clearance of our IND, encouraging Phase 1 results and a strong financial position, we expect to commence the Phase 2 ASCENTRA-UC trial in the second half of 2026. PALI-2108 was engineered for targeted activation within the gastrointestinal tract, with the goal of delivering sustained PDE4 inhibition while improving tolerability and convenience. We believe the ASCENTRA-UC Phase 2 trial represents a significant opportunity to demonstrate that differentiated profile in a larger patient population and establish PALI-2108 as a potentially best-in-class, once-daily oral therapy for IBD."

Advancing PALI-2108 Into Phase 2 Development

Phase 2 ASCENTRA-UC

Received FDA clearance of the IND application for PALI-2108
Phase 2 UC clinical trial expected to commence in 2H 2026
Primary efficacy readout expected 2H 2027

Phase 2 ASCENTRA-CD

IND submission for the Phase 2 CD trial expected 2H 2026
Phase 2 CD clinical trial commencement targeted for 1Q 2027
Primary efficacy readout expected in early 2028

Mitch Jones, M.D., Ph.D., President and Chief Medical Officer of Palisade Bio, added, "Crohn’s disease is a core component of the PALI-2108 clinical development program and is advancing in parallel with ASCENTRA-UC. We believe that PALI-2108’s targeted activation and localized delivery in both the ileum and colon are particularly relevant to Crohn’s disease, which can affect multiple regions of the gastrointestinal tract. We are finalizing the design of the Phase 2 ASCENTRA-CD trial and expect to submit an IND in the second half of 2026. With active programs in both Crohn’s disease and ulcerative colitis, PALI-2108 is positioned to address the two largest indications within IBD."

Summary of Financial Results

Research and development expenses were $7.4 million for the three months ended June 30, 2026, compared to $1.7 million for the three months ended June 30, 2025. The increase was primarily attributable to higher research and development employee-related expenses, including increased non-cash stock-based compensation expense, and higher PALI-2108 program expenses driven by increased clinical operation expenses, increased chemistry, manufacturing and controls (CMC) activities and expanded preclinical and translational science efforts supporting advancement of PALI-2108 into Phase 2 development.

General and administrative expenses were $4.8 million for the three months ended June 30, 2026, compared to $1.2 million for the three months ended June 30, 2025. The increase was primarily attributable to higher employee-related expenses, including increased non-cash stock-based compensation expense, as well as higher professional fees supporting the Company's continued growth and clinical advancement.

The Company recognized license revenue of $0.5 million for the three months ended June 30, 2026 related to the achievement of a milestone pursuant the co-development and distribution agreement with Newsoara, a joint venture established by Biolead Medical Technology Limited. No license revenue was recognized for the three months ended June 30, 2025.

Net loss was $10.6 million, or a net loss of $0.05 per share, for the three months ended June 30, 2026, compared to a net loss of $2.8 million, or a net loss of $0.58 per share, for the three months ended June 30, 2025.

As of June 30, 2026, the Company had $125.2 million in cash and cash equivalents and believes its existing cash resources are sufficient to fund operations through major clinical development milestones, including the anticipated primary efficacy readout from the Phase 2 ASCENTRA-UC trial expected in the second half of 2027 and the planned primary efficacy readout from the Phase 2 ASCENTRA-CD trial expected in early 2028.

About Palisade Bio

Palisade Bio, Inc. (NASDAQ:PALI) is a clinical-stage biopharmaceutical company developing prodrugs for patients living with inflammatory and fibrotic diseases.

The Company’s lead clinical product candidate, PALI-2108, is being advanced into Phase 2 clinical trials as a treatment for patients living with inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD). Despite the availability of multiple biologic and small-molecule therapies, many patients with UC and CD do not achieve durable remission, lose response over time, or discontinue treatment because of safety or tolerability limitations. The Company believes PALI-2108 has the potential to address these limitations through once-daily oral dosing, targeted lower-intestinal bioactivation and broad PDE4-mediated anti-inflammatory activity.

Palisade Bio is now advancing into Phase 2 development for UC and CD. For more information, please go to www.palisadebio.com.
