             or without metformin), and is inadequately controlled. Metformin dose must be stable
             for at least 8 weeks prior to Randomization.

             weeks prior to Randomization.

          -  Body mass index greater than or equal to 23 kg/m2 and less than or equal to 45 kg/m2

          -  Fasting C-peptide concentration greater than or equal to 0.8 ng per mL. (If this
             screening criterion is not met, the subject still qualifies if C-peptide greater than
             or equal to 1.5 ng per mL after a challenge test).

          -  Glycosylated hemoglobin concentration greater than or equal to 8.0% at Screening.

          -  Using a stable dose of insulin of at least 15 units but not more than 100 units per
             day for at least 8 weeks prior to Randomization. A dose of insulin that varies by up
             to 15% of the mean will be considered as stable.

          -  If regular use of other, non-excluded medications, must be on a stable dose for at
             least the 4 weeks prior to Screening. However, as needed use of prescription or
             over-the-counter medications is allowed at the discretion of the investigator.

          -  Systolic blood pressure less than or equal to180 mm Hg and diastolic pressure less
             than or equal to 110 mm Hg

          -  Hemoglobin greater than or equal to 12 g per dL for males and greater than or equal
             to10 g per dL for females.

          -  Alanine aminotransferase less than or equal to 3 times the upper limit of normal.

          -  Serum creatinine less than or equal to 2.0 mg per dL.

          -  Thyroid-stimulating hormone level less than or equal to the upper limit of the normal
             range and the subject is clinically euthyroid.

          -  Neither pregnant (confirmed by laboratory testing in females of childbearing
             potential) nor lactating.

          -  Female subjects of childbearing potential must be practicing adequate contraception.
             Adequate contraception must be practiced for the duration of participation in the
             study.

          -  Able and willing to monitor own blood glucose concentrations with a home glucose
             monitor

          -  No major illness or debility that in the investigator's opinion prohibits the
             individual from completing the study

          -  Able and willing to provide written informed consent

        Exclusion Criteria

          -  Urine albumin to creatinine ratio of greater than 1000 μg per mg at Screening. If
             elevated, the subject may be rescreened within 1 week.

          -  History of laser treatment for proliferative diabetic retinopathy within the 6 months
             prior to Screening.

             study.

             myocardial infarction within the 6 months prior to Screening.

          -  History of any hemoglobinopathy that may affect determination of glycosylated
             hemoglobin.

          -  History of infection with hepatitis B, hepatitis C, or human immunodeficiency virus.

          -  History of a psychiatric disorder that will affect ability to participate in the
