Palisade Bio to Present Clinical and Translational Data for PALI-2108 in Ulcerative Colitis and Crohn’s Disease at UEG Week 2026

Oral presentation to highlight early endoscopic improvement and evidence of PDE4 target engagement in fibrostenotic Crohn’s disease

Three moderated posters to showcase gut-targeted exposure, favorable safety and tolerability, rapid clinical response in ulcerative colitis, and the development of a biomarker to predict treatment response

Denver, CO, Sept. 28, 2026 (GLOBE NEWSWIRE) -- Palisade Bio, Inc. (Nasdaq: PALI) (“Palisade” or the “Company”), a clinical-stage biopharmaceutical company developing next-generation prodrugs for patients living with inflammatory and fibrotic diseases, today announced that its lead program, PALI-2108, will be featured in four presentations at United European Gastroenterology (UEG) Week 2026. The presentations include an oral presentation of Phase 1b findings in fibrostenotic Crohn’s disease and three moderated posters. The conference will take place October 17–20, 2026, in Barcelona, Spain.

The presentations will highlight early clinical activity in ulcerative colitis (UC) and fibrostenotic Crohn’s disease (FSCD), gut-targeted exposure and differentiated pharmacokinetics, and favorable safety and tolerability. They will also feature a mechanistically anchored transcriptomic biomarker being prospectively validated to help predict treatment response in UC. Together, these provide additional clinical and translational support for the continued development of PALI-2108 as a once-daily oral treatment for inflammatory bowel disease. PALI-2108 is currently being advanced into Phase 2 clinical development in both UC and CD.

Presentation details are as follows:

About PALI-2108

PALI-2108 is an oral, locally activated PDE4 inhibitor prodrug designed for once-daily dosing and targeted bioactivation in the terminal ileum and colon. Across Phase 1 studies in healthy volunteers and patients with ulcerative colitis and fibrostenotic Crohn’s disease, PALI-2108 demonstrated favorable safety and tolerability, differentiated pharmacokinetics and exposures supportive of sustained PDE4 inhibition, supporting continued advancement in Phase 2 clinical trials.

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.
