Summary

PALI-2108 is a new oral medication designed to treat ulcerative colitis (UC) by targeting the intestines. It works as a phosphodiesterase-4 (PDE4) inhibitor prodrug, meaning it becomes active only after being processed by bacteria in the colon. This targeted approach reduces the risk of side effects that can occur with other medications that affect the entire body.

Recent studies have shown that patients with active UC, especially those with moderate to severe symptoms, have higher levels of PDE4 and related biomarkers. These biomarkers are linked to the severity of their disease, suggesting that inhibiting PDE4 could help manage UC effectively.

The goal of this Phase 1 study is to evaluate the safety, tolerability, and how the body processes (pharmacokinetics) and responds to (pharmacodynamics) PALI-2108 in healthy volunteers. Although there are already PDE4 inhibitors on the market, PALI-2108 is a completely new compound that has not been tested in humans before. The study will involve two parts: first, participants will receive single doses of the drug, and then, in the second part, they will take it twice a day for seven days.

The twice-daily dosing schedule is designed to maximize drug exposure in the colon. The investigators will also investigate how food affects the drug's absorption.

Additionally, a small group of stable UC patients will be included in the study. These patients will also take PALI-2108 for seven days, allowing us to compare the safety and drug processing between healthy individuals and those with UC. The investigators will monitor important health markers and conduct tests on colon tissue to see how well the drug works and if it causes any changes in the tissue.

Including UC patients early in this research is important for understanding how the drug performs in real-world conditions. This data will help refine our approach to identify which patients might benefit most from PALI-2108 in future studies.

Overall, this study aims to gather crucial information about PALI-2108's safety and effectiveness, paving the way for new treatment options for patients with ulcerative colitis.
