Study Overview
=================
Brief Summary
-----------------
This is a 26-week randomized, open-label, multicenter, active-controlled parallel group trial. The purpose of this study is to compare efficacy and safety of THDB0206 injection with insulin lispro injection combined with insulin glargine injection U-100 in Chinese participants with T2DM.
