Overview

YUQ-A1007 is a novel gut-enriched AhR agonist. The nonclinical pharmacology study indicated that YUQ-A1007 has the potential to treat IBD.

YUQ-A1007 has not been evaluated in human clinical studies. This study is first-in-human (FIH) study of YUQ-A1007. The goal of this trial is to evaluate the safety, tolerability, and pharmacokinetics of oral YUQ-A1007.
