Brief Summary

This is a randomized, double-blind, active control, parallel group, exploratory phase 4 study to compare the effect of teneligliptin versus sitagliptin on glucose variability when added on to metformin in patients with inadequately controlled type 2 diabetes mellitus.

Detailed Description

This study will enroll patients with in adequately controlled type 2 diabetes mellitus who have been on metformin (1,000 mg or above) for 8 weeks at least or longer and randomly add teneliglipin (20 mg/day) or sitagliptin (100 mg/day) for 4 weeks. Continuous glucose monitoring will be checked before and after 4-week administration of teneliglipin or sitagliptin together with mixed meal tolerance test (MMTT). Other efficacy and safety parameters will be also assessed.

8. Male and female patients and their partners who have been surgically sterilized for less than 6 months prior to study entry must agree to use 2 medically accepted methods of contraception as per inclusion criterion 7.

9. Menopausal females must have experienced their last period more than 12 months prior to study entry to be classified as not of childbearing potential.

10. Patient (or legal guardian, if applicable) is informed of the full nature and purpose of the study, including possible risks and side effects, and understand this information, voluntarily signed and dated the written informed consent in compliance with protocol before inclusion in the study

Exclusion Criteria

1. Patients who have hypersensitivity/allergies to main ingredient of sitagliptin/teneligliptin or any of the excipients of Investigational products(eg. Mannitol).

2. Patient with severe ketosis, diabetic coma or pre coma, Type 1 DM

3. Patient is suffering from any disease, including Type 2 diabetes or its complications that, in the opinion of the Investigator, is sufficiently severe to render the subject unfit, or affect the subject's ability, to participate in the study, for example:

• Macroangiopathy with symptoms of coronary heart disease or peripheral arterial obstructive disease.
• Microangiopathy with symptoms of (autonomous) neuropathy with any one or more of the following: gastroparesis
• Symptoms of poor blood glucose control (polyuria, polydipsia or weight loss)
• Severe infection, pre or post-operative, severe trauma

4. Patient 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

5. The subject has diastolic blood pressure >100 mmHg and/or systolic blood pressure >180 mmHg at the screening visit

6. Patient who has malignancy at screening or history of any malignancy (except history of no recurrence of malignancy more than 5 years)

7. Female patient whose pregnancy test is negative or who are pregnant, lactating, or are planning to become pregnant during the study

8. Patient is expected to require additional diabetic treatment for his/her Type 2 diabetes or its complications during the study after the screening visit

9. Patient has a history of drug abuse

10. Patient who is under malnutrition, weakness or, in the opinion of the Investigator, patient who drinks on average more than 28 units of alcohol per week (One unit of alcohol equals approximately 250 mL of beer, 125 mL of wine or 40 mL of spirits)
