Study Overview
=================
Brief Summary
-----------------
This study is to evaluate safety and efficacy of ASP1941 after 24 week administration to diabetic patients.

Detailed Description
-----------------
Subjects will undergo the 6-week screening period before entering the 24-week treatment period and will receive ASP1941 before breakfast during the treatment period. All subjects will be followed for 4 weeks after study treatment is discontinued.

Inclusion Criteria: Type 2 diabetes mellitus patients Subject is only on a diet and exercise program or has received a single antihyperglycemic agent or two antihyperglycemic agents (excluding insulin) with low dose (≤50% of the maximum dose of each recommended dosage) Subject has a HbA1c value (JDS value) between 6.5% and 9.5% and the difference of HbA1c values (JDS value) within ± 1.0% BMI 20.0 - 45.0 kg/m2 Exclusion Criteria: Type 1 Diabetes Mellitus Subject has received insulin within 12 weeks (84 days) before the study Subject has proliferative diabetic retinopathy Subject has a history of clinically significant renal disease such as renovascular occlusive disease, nephrectomy and/or renal transplant Subject with obvious dysuria caused by a neurogenic bladder or a benign prostatic hypertrophy Subject has a history of cerebral vascular attack, unstable angina, myocardial infarction, vascular intervention, and heart disease (NYHA Class III-IV) within 12 weeks (84 days). Subject has heart disease, cerebral vascular disease which, in the opinion of the principal investigator or the sub-investigator, may interfere with treatment or evaluation of safety of this study.
