The double-blind, placebo-contDF-003 Phase I trial (NCT0FDA7641) is evaluating the safety, tolerability, and pharmacokinetics of DF-003 on 96 healthy subjects.  The study is expected to conclude in Q1 2025.
The company has other candidates in the pipeline, including another ALPK1 agonist DF-006, which is under investigation in the thiDF-003t of a Phase I study for the treatment of chronic hepatitis B infection.
