Company on track to commence Phase 1 human clinical study of PALI-2108 for the treatment of Ulcerative Colitis (UC) before year end

*Carlsbad, CA, May 01, 2024 (GLOBE NEWSWIRE) -- *Palisade Bio, Inc. (Nasdaq: PALI) (“Palisade”, “Palisade Bio” or the “Company”), a biopharmaceutical company focused on developing and advancing novel therapeutics for patients living with autoimmune, inflammatory, and fibrotic diseases, announced today the successful completion of its analysis to determine the effects of bioactivated PALI-2108 on TNF-α production in a whole blood (WB) assay. PALI-2108 is Palisade’s orally administered, locally acting, colon-specific phosphodiesterase-4 (PDE4) inhibitor prodrug in development for patients affected by UC.

"These important data bolster our confidence in the robust anti-inflammatory potential of PALI-2108 in the management of UC," said Dr. Mitch Jones, CMO of Palisade Bio. "The superior efficacy of PALI-2108, as demonstrated by its lower half-maximal inhibitory concentration (or IC50) compared to the approved PDE4 inhibitor apremilast, underscores its potential as a next-generation therapeutic option for patients with inflammatory bowel disease."

This study included WB samples from 14 clinically healthy adults (five women and nine men). Twelve samples meeting the inclusion criteria were included for TNF-α measurement and calculation of IC50 values. Donor whole blood was treated with different concentrations of PALI-2108 and two control compounds known to inhibit the PDE4 pro-inflammatory pathway. Blood was then challenged with the pro-inflammatory molecule lipopolysaccharide (LPS). Anti-inflammatory potency was determined by calculating the IC50 values for TNF-α inhibition.

Findings from the study demonstrated that PALI-2108 exhibited efficacy in inhibiting TNF-α production induced by LPS in this ex-vivo peripheral whole blood assay. Pre-treatment of human whole blood samples with bioactivated PALI-2108 resulted in a significant reduction in LPS-induced TNF-α production compared to non-pretreated samples. Specifically, the Company’s proprietary PDE4 inhibitor, shown to be released by the local bioconversion of PALI-2108 prodrug in the colon, demonstrated a mean IC50 for TNF-α inhibition of 0.022 µM, compared to 0.41 µM for apremilast, showcasing its potent anti-inflammatory activity. The study was conducted in collaboration with Paraza Pharma, Inc based in Montreal, QC.

JD Finley, CEO of Palisade Bio, added “Our team’s exceptional operational execution is driving the clinical development of PALI-2108 towards our first-in-human study, which is on track to start later this year. We are committed to advancing our pioneering research initiatives aimed at improving the lives of patients suffering from UC and other inflammatory conditions.”
