Brief Summary

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

The hypothesis of this Phase 2, 12-week study, is that DS-8500a will improve glycemic control relative to placebo, based on changes in HbA1c, with acceptable safety and tolerability, in patients with Type 2 Diabetes Mellitus (T2DM) who are treated with metformin.

Exclusion Criteria

* History of type 1 diabetes and/or history of ketoacidosis
* History of insulin use for \> 2 weeks within 2 months prior to the Screening Visit
