             months prior to the time of screening

          -  Known history of drug or alcohol abuse within 6 months prior to the time of screening

          -  Cardiovascular, hepatic, neurological, endocrine disease, active malignant tumor or
             other major systemic disease or patients with short life expectancy making
             implementation of the protocol or interpretation of the study results difficult,

          -  Any clinically significant abnormality identified on physical examination, laboratory
             tests, electrocardiogram, or vital signs at the time of screening that, in the
             judgment of the investigator or any sub-investigator, precludes safe completion of the
             study or constrains efficacy assessment

          -  Patients who are considered by the investigator or any sub-investigator as
             inappropriate for this study for any reason (for example, impossibility to meet
             specific protocol requirements [such as scheduled visits, being able to do
             self-injections]; likelihood of requiring treatment during the screening phase and
             treatment phase with drugs not permitted by the clinical study protocol; investigator
             or any sub-investigator, pharmacist, study coordinator, other study staff or relative
             thereof directly involved in the conduct of the protocol)

          -  Use of other oral or injectable antidiabetic or hypoglycemic agents other than
             metformin (for example, sulfonylurea, alpha glucosidase inhibitor, other
             thiazolidinediones, rimonabant, exenatide, dipeptidyl-peptidase-4 inhibitors, insulin)

             lixisenatide

             in the study, as assessed by the investigator
