Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will assess the efficacy and safety of initial treatment with sitagliptin and metformin in patients with type 2 diabetes mellitus in China. The primary hypothesis is that after 24 weeks, initial co-administration treatment with sitagliptin and metformin provided greater reduction in hemoglobin A1C (A1C) compared to initial treatment with sitagliptin alone and with metformin alone.
