Carlsbad, CA, July 19, 2024 (GLOBE NEWSWIRE) -- Palisade Bio, Inc. (Nasdaq: PALI) (the “Company”), a biopharmaceutical company focused on developing and advancing novel therapeutics for patients living with autoimmune, inflammatory, and fibrotic diseases, today announced that European Patent Office (EPO) has issued a decision to grant notice for patent number 4,157,853 titled, “Gut Microbiota Bioactivated PDE4 Inhibitor Precursors.” Based on the intention to grant notice, the Company expects the EPO to issue a patent July 31, 2024. In addition to this European patent and recently allowed Canadian patent, the Company continues to strengthen its global intellectual property portfolio surrounding PALI-2108 with submitted and planned submissions of additional patent applications.

J.D. Finley, Chief Executive Officer of Palisade commented, “We are pleased to further expand our global patent estate for our PALI-2108 and PALI-1908 programs with this European patent. PALI-2108 continues to demonstrate encouraging data and bolster our confidence in its potential as a next-generation therapeutic option for patients with inflammatory bowel disease. As we continue to execute on the development pathway forward for PALI-2108 and PALI-1908, we remain committed to strengthening our global intellectual property portfolio.”

The patent claims include coverage for the proprietary composition of PALI-2108, the Company’s orally administered, locally acting colon-specific Phosphodiesterase-4 (PDE4) inhibitor prodrug in development for patients affected by Ulcerative Colitis (UC). PALI-2108’s unique design, incorporating a galactose-derived sugar moiety, potentially allows for minimal absorption until cleaved by the colonic bacterium enzyme β-glucuronidase. This feature is intended to ensure localized bioactivation, leading to colon-specific distribution with limited systemic exposure, as shown by a tissue distribution study.

Palisade continues to advance PALI-2108 for the treatment of moderate-to-severe UC toward a Phase 1 clinical study, expected to be initiated before the end of 2024. The Company’s PALI-1908 candidate is a microbiota-activated PDE4 inhibitor prodrug that leverages the advancements made with PALI-2108 and is being developed for the treatment of fibro stenotic Crohn’s Disease.

Palisade Bio is a biopharmaceutical company focused on developing and advancing novel therapeutics for patients living with autoimmune, inflammatory, and fibrotic diseases. The Company believes that by using a targeted approach with its novel therapeutics it will transform the treatment landscape. For more information, please go to www.palisadebio.com.
