Inclusion Criteria

Inclusion criteria (assessed during screening):
1.Male, non-fertile female or female of childbearing potential using a medically approved birth control method.

•A female of childbearing potential is defined as any woman physiologically capable of becoming pregnant, including women whose career, lifestyle, or sexual orientation precludes intercourse with a male partner and women whose partners have been sterilized by vasectomy or other means.
•Medically approved birth control method include: hormonal contraceptives, IUD, and double-barrier contraception. Acceptable methods of contraception may include total abstinence at the discretion of the investigator in cases where the age, career, lifestyle, or sexual orientation of the subject ensures compliance.

•Reliable contraception should be maintained throughout the study.

4.Diagnosis of T2DM for at least 2 months prior to study entry (visit 1).
5.Body mass index (BMI) in the range of 22-45 kg/m2 inclusive at visit 1.
6.HbA1c in the range of 6.5-9% inclusive at visit 1.
7.FPG < 270 mg/dL (15 mmol/L) at visit 1 (measurement may be repeated once to confirm FPG value).
8.Written informed consent to participate in the study.
9.Ability to comply with all study requirements.
