A Phase 3 Study to Evaluate the Efficacy of XW003 Compared With Placebo in T2DM Patients

A Phase 3, Multi-center, Double-blind, Randomized, Placebo-controlled Study to Evaluate the Efficacy and Safety of XW003 in Patients With T2DM Inadequately Controlled by Diet and Exercise Alone

The main purpose of this study is to investigate the efficacy and safety of XW003 versus placebo in patients with type 2 diabetes mellitus (T2DM) inadequately controlled by diet and exercise alone

In this Phase 3 study, eligible participants will be randomized in a 2:2:1:1 ratio to receive once-weekly subcutaneous XW003 (high or low dose) or volume matching placebo as an adjunct to lifestyle intervention for 24 weeks. The core treatment phase will be followed by a 28-week open-label period where all participants receive XW003.
