XW004 To Evaluate the Safety, Tolerability, PK, and PD of Oral Ecnoglutide Tablet in Healthy Adults

This is a single centre, double-blind, randomised, multiple-dose, placebo-controlled study, including six cohorts (Cohorts 1A/1B, 2, 3, 4, 5, 6) with a semi-parallel design. The study is designed to evaluate the safety, tolerability, PK, and PD of oral ecnoglutide tablet in healthy participants. Participants will undergo a Screening period beginning up to 28 days (Cohort 1 to 4) and 42 days (Cohort 5 and 6 ) prior to randomisation/dose administration and will be required to sign an informed consent form (ICF) before undertaking any study specific procedures or assessments. Participants who meet all of the inclusion and none of the exclusion criteria will be enrolled. Eligible participants will be admitted to the CRU on Day -1 for review of inclusion and exclusion criteria prior to the start of study procedures on Day 1. A Safety Review Committee (SRC) will be established to monitor the progress of this trial and to make recommendations on whether to continue, modify or stop the trial for safety or ethical reasons.
