Palisade Bio, Inc. (Nasdaq: PALI) (“Palisade” or the “Company”) is a clinical-stage biopharmaceutical company advancing a next-generation oral PDE4 inhibitor prodrugs designed to improve pharmacology, tolerability, and convenience for patients with inflammatory and fibrotic diseases. Through its differentiated prodrug platform and precision pharmacology strategy, Palisade Bio is committed to transforming proven PDE4 biology into better, safer oral therapies for patients living with chronic inflammatory and fibrotic diseases.

The Company’s lead program, PALI-2108, is a once-daily, ileum- and colon-targeted, locally bioactivated PDE4 inhibitor prodrug being developed for moderate-to-severe Ulcerative Colitis (UC) and fibrostenotic Crohn’s Disease (FSCD), two diseases with limited non-immunosuppressive therapy options. In a recently reported Phase 1b trial, PALI-2108 achieved a 100% clinical response in the UC cohort, with no serious adverse events, favorable tolerability and pharmacokinetics consistent with localized activation in the lower intestine, low systemic exposure, and controlled release within the GI tract.

Palisade Bio is now advancing towards a Phase 2 clinical study in UC designed to evaluate clinical remission, response and pharmacodynamic biomarkers over 12 weeks, with an extension phase assessing maintenance of remission. In addition, the Company is preparing to initiate studies in FSCD to further characterize PALI-2108’s safety, pharmacology and therapeutic benefit across inflammatory bowel disease indications.
