PALI-2108, A COLON-SPECIFIC PDE4 INHIBITOR PRODRUG, IS BIOACTIVATED IN THE COLON AND REDUCES COLON TISSUE PDE4B IN A DOSE-DEPENDENT MANNER, INCREASING C-AMP AND SUPPRESSING TNF-Α IN A MOUSE MODEL OF COLITIS (DDW 2025) - "Interestingly the elevation of cAMP levels leads to a reduction of cytokine TNF-α levels close to normal levels associated with reduced levels of inflammation in the PALI-2108 treatment cohorts, Cyclosporin A or apremilast treatment did not lower TNFa levels as much as PALI-2108 treatment (see Figure 2)... PALI-2108 is a colon-specific PDE4 inhibitor for the treatment of UC and other inflammatory bowel diseases (IBD). By preventing the degradation of intracellular cAMP, PALI-2108 modulates downstream pro-inflammatory factors and promotes anti-inflammatory cytokines within the lamina propria. Our preclinical data demonstrate that PALI-2108 effectively reduces colitis symptoms in a dose-dependent manner, supporting its potential as a viable alternative for treating UC."

A BIOINFORMATIC APPROACH TO PALI-2108 TREATMENT IN ULCERATIVE COLITIS REVEALS THE POTENTIAL FOR ANTI-FIBROTIC EFFICACY WITH LOCAL PDE4 INHIBITION IN INTESTINAL FIBROSIS (DDW 2025) - " We identified cAMP-regulated signatures that demonstrated ~100% sensitivity and 70% specificity for predicting infliximab response in UC patients in silico...Fig 2: Fibrotic Pathway Expression Score for cohorts treated with, apremilast and PALI-2108 in a DSS mouse model of colitis... Our findings suggest that cAMP-regulated drivers of inflammation are activated in both UC and fibrostenotic CD. Therapy leading to a reduction of cAMP regulated inflammation could offer new treatment options for patients. PALI-2108's potential to engage antifibrotic pathways may provide a novel therapy to treat fibrostenotic CD."

PALI-2108 administration resulted in a marked dose-dependent reduction of PDE4B expression in colon tissues, with higher cAMP levels and a notable suppression of TNF-α compared to standard treatments like cyclosporine A and apremilast."
