Brief Summary:
This study is intended to prospectively research the treatment reality and long-term disease control of Type 2 Diabetes Mellitus (T2DM) patients who are initiating 2nd line anti-diabetes treatment in sites across Japan.

Condition or disease
Type 2 Diabetes Mellitus

Detailed Description:
This study is a single country, multicenter, observational, prospective, longitudinal cohort study which will include adult patients with documented history of T2DM who are initiating a second line oral or parenteral anti-diabetes mediation after their first line anti-diabetic therapy in real world setting. The follow-up period is 3 years. Patients will undergo clinical assessments and receive standard medical care as determined by the treating physician. Patients will not receive experimental intervention or experimental treatment as a consequence of their participation in the study.
