Brief summary: The study design of this trial is double blind, parallel-group, randomized, placebo controlled study

Detailed description: * Although many different oral antidiabetic agents are currently available, approximately 50% of treated Type 2 diabetic subjects do not reach currently accepted goals for HbA1c(Oral communication, American Diabetic Association, 2008)Subjects are frequently prescribed agents which can cause hypoglycemia, and/or weight gain.
* In many countries, the most commonly prescribed primary oral diabetes drug that does not cause hypoglycemia or weight gain, is metformin, but metformin can cause gastrointestinal adverse drug reactions, nausea, vomiting, diarrhea, abdominal pain and loss of appetite and other symptoms, and rare but life-threatening lactic acidosis.
* This decrease in the Power of Hydrogen Ions of the blood (\<7.25) and the increase in blood lactate (\> 5 mmol / L) is associated with a reduced kidney failure and if there is kidney impairment, decreased metformin clearance and thus accumulated metformin may occur lactic acidosis more frequently. Also there is inconvenience, such as adjusting metformin dose depending on patient's condition.
* MP-513 is expected to be safely used as a treatment for type 2 diabetes because it has no risk of hypoglycemia and/or weight gain which are reported in pre-existing diabetes therapies and no inconvenience related to dose adjustment depending on patient's condition, and no cases of fatal side effects.
* Furthermore the inhibitory effect on Dipeptidyl peptidase-IV was stronger and half-life was longer compared with other dipeptidyl peptidase-IV inhibitors in non-clinical trial, and blood glucose moderating effects are proven to be clinically significant in clinical trials conducted in Europe and Japan in that its development as a therapeutic agent for patients with type 2 diabetes is considered to be promising.
* Based on these previous studies, the objective of this study is to investigate the efficacy and safety in subjects with type 2 diabetes mellitus that is not adequately controlled with exercise and diet.

Eligibility criteria: Inclusion Criteria:

1. The subject is aged ≥18 years at signature of the informed consent form
2. The subject has a documented diagnosis of Type 2 diabetes
3. The subject's HbA1c is 7.0%≤HbA1c\<10.0% at screening visit and run-in visit
4. The subject's BMI is 20.0≤BMI≤40.0kg/m2
5. The subject's fasting plasma glucose is \<15 mmol/L (270 mg/dL)at screening visit and run-in visit
6. The subject conducts a proper diet and exercise therapy for diabetes and its contents have not been changed for at least 8 week(56 days) at run-in visit(this does not apply to a subject with complications as as result of that exercise therapy is impossible)
7. The subject has not used other diabetic medicine for at least 8 week(56 days) at run-in visit
8. The subject is capable of giving informed consent, complying with the restrictions and requirements of the protocol

Exclusion Criteria:

1. The subject has a history of Type 1 diabetes or a secondary form of diabetes(Diabetes caused by the pancreatic diseases, such as chronic pancreatitis, pancreatic cancer, hemochromatosis or the overproduction of hormones antagonistic to insulin, Cushing's syndrome, Basedow's disease, pheochromocytoma, drug, insulin receptor abnormalities)
2. The subject has a history of MP-513 treatment
3. The subject has a history of habitual and excessive alcohol abuse or drug abuse, or concerns
4. The subject has a medical history of unstable angina, or heart failure(New York Heart Association class Ⅲ-IV) or any clinically significant ECG abnormalities such as ventricular tachycardia or a medical history of ventricular tachycardia
5. The subject has participated in any other clinical study involving administration of an unlicensed medicinal product within 12 weeks prior to the screening visit or is participating any other clinical study
6. The subject has received insulin within 12 months prior to the screening visit, with the exception of insulin therapy during hospitalization, insulin therapy for medical conditions not requiring hospitalization (\<2 weeks duration) or use in gestational diabetes
7. Female subjects whose pregnancy test is positive or who are pregnant, lactating, or are planning to become pregnant during the study
8. The subject has serum creatinine \>1.5 mg/dL(male) or \>1.4 mg/dL(female)
9. The subject has aspartate-amino-transferase (AST) and alanine-amino-transferase (ALT) \>2.5 times the upper limit of normal (ULN)
10. The subject has diastolic blood pressure \>100 mmHg and/or systolic blood pressure \>180 mmHg
11. The presence of any other condition that leads the investigator to conclude that the patient is inappropriate for inclusion in the clinical study
