Palisade Bio Successfully Demonstrates Bioactivation of PALI-2108 In Ex-Vivo Study of Normal Healthy and Ulcerative Colitis Patients’ Stool

Company continues advancing ongoing development of targeted therapies for ulcerative colitis (UC)

Carlsbad, CA, April 16, 2024 (GLOBE NEWSWIRE) --  (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 evaluating ex-vivo bioactivation of PALI-2108, an orally administered, locally acting colon-specific phosphodiesterase-4 (PDE4) inhibitor prodrug in development for patients affected by UC.

These findings demonstrated that PALI-2108 exhibited efficient ex-vivo conversion into its active PDE4 inhibitor form in stool samples from both normal healthy volunteers and patients with UC. The enzymatic activity in stool samples was assessed using LC-MS analysis with all stool samples meeting the target conversion rate within a 24-hour period. The assessment showed PALI-2108 was converted into its active PDE4 inhibitor form at a mean rate of 90.1% with conversion steadily increasing over time. The study was conducted in collaboration with Altasciences based in Montreal, QC.

"The results from this study underscore our confidence in PALI-2108 as a targeted treatment for moderate-to-severe UC," said Dr. Mitch Jones, CMO at Palisade Bio. "The successful bioactivation of prodrug PALI-2108 into its active PDE4 inhibitor form at consistently high conversion rates over a 24-hour period in stool samples highlights its promise as an innovative therapeutic approach for managing UC."
