Bio Announces Positive Preclinical Data of Lead Program
at the 2024 Crohn's & Colitis Congress
Preclinical data demonstrated PALI-2108 to be safe and well tolerated
PALI-2108 is orally delivered and colon activated allowing for local activity with low systemic exposure
Company advancing PALI-2108 for the treatment of moderate-to-severe ulcerative colitis (UC) toward Phase 1 clinical study, expected to
CA - January 29, 2024 - Palisade Bio, Inc. (Nasdaq: PALI) ("Palisade" or the "Company"),
a biopharmaceutical company focused on developing novel therapeutics for serious chronic gastrointestinal (GI) diseases, today announced
the presentation of positive preclinical data of its lead asset, PALI-2108 at the Crohn's & Colitis Congress, which
was held on January 25-27, 2024 in Las Vegas, NV.
preclinical data was presented in a poster titled, Local Bioactivation and Efficacy of PALI-2108: A Promising PDE4 Inhibitor Prodrug
for Ulcerative Colitis Treatment. PALI-2108 is the Company's orally administered, locally acting colon-specific phosphodiesterase-4B
(PDE4B) inhibitor prodrug in development for patients affected by moderate-to-severely active ulcerative colitis (UC). The poster is
available on the Scientific Publications page of the Company's website.
Jones, M.D., Ph.D., Chief Medical Officer of Palisade Bio, commented, "PALI-2108 continues to demonstrate promise as a novel therapy
for UC, with colon-selective bioactivation, an expanded therapeutic window, reduced CNS toxicity, potent PDE4 inhibitory activity, and
impressive efficacy in preclinical models. We are pleased with our growing body of evidence, including support for a precision medicine
approach and the selection of potential responders, which validate the continued development of this program. We are working diligently
to launch our Phase 1 study later this year, and we are eager to continue to gain experience on the potential of this groundbreaking
PDE4 inhibitor prodrug therapy. The journey ahead holds great promise for advancing UC treatment, and we are committed to making a meaningful
impact for patients."
results presented at the Crohn's and Colitis Foundation include several preclinical studies of PALI-2108, a novel oral PDE4 inhibitor
prodrug designed for the treatment of ulcerative colitis (UC). The Company's research has focused on addressing the limitations
of current PDE4 inhibitors, such as CNS toxicity and systemic distribution, which often lead to therapy discontinuation.
preclinical studies, PALI-2108 demonstrated promising outcomes. In a DSS-induced UC mouse model, researchers observed a significant reduction
in disease activity index (DAI) score over time compared to the control group. Notably, body weight loss was attenuated in specific dosage
groups, showcasing the potential for targeted efficacy.
unique design, incorporating a galactose-derived sugar moiety, allows for minimal absorption until cleaved by the colonic bacterium enzyme
-glucuronidase. This feature ensures localized bioactivation, leading to colon-specific distribution with limited systemic exposure,
as confirmed by a tissue distribution study. The colon/plasma AUC ratio exceeding 200 further highlights PALI-2108's preference
addition, the Company's research demonstrates colon-selective bioactivation in oxazolone colitis-induced mice, negligible plasma
levels in duodenal and ileal tissue, and comparable target engagement with other PDE4 inhibitors. As well, a tolerated dose study in
dogs revealed no CNS toxicity or emesis over effective doses, addressing a critical concern associated with oral administration.
is emerging as a promising candidate for UC therapy, offering localized bioactivation, expanded therapeutic window, and potent PDE4 inhibitory
activity. We believe this innovative approach has the potential to revolutionize UC treatment and enhance patient outcomes," added
summary, results of the Company's preclinical studies showed that PALI-2108 demonstrated:
| Local bioactivation; | ||
| Colon-specific distribution; | ||
| Similar target engagement to other PDE4 inhibitors; | ||
| Dose-dependent efficacy in a mouse UC model; and | ||
| No systemic toxicity in dogs and large therapeutic window due to local activation. |
bowel disease (IBD) represents a multi-billion-dollar market opportunity in need of innovative approaches, with current therapies achieving
a clinical remission rate of less than 20% on average.
Bio is a biopharmaceutical company focused on developing novel therapeutics for serious chronic gastrointestinal diseases. The Company
