- Target Population Diagnosis of T1DM. In addition, the following criteria also needs to be met; Central laboratory test of C-peptide < 0.7ng/mL
Subject re-enrolment: This study does not permit the re-enrolment of a subject who has discontinued the study as a screen failure
- Insulin use for at least 12 months prior to the enrolment per subject report or medical records and Method of insulin administration (MDI) must have been unchanged for at least 3 months prior to the enrolment per subject report or medical records. Subjects must be taking a total daily insulin dose of 0.3U/kg/day or more for at least 3 months prior to the enrolment. CSII users are excluded. MDI insulin administration subject must be on 3x injections per day or more.
- Gender and reproductive Status Japanese men and women.
- HbA1c eligibility criteria include: Screening Visit: Central laboratory HbA1c 7.0% or more and 10.0% or less (One repeat HbA1c test for subjects in screening if their initial test result was an HbA1c +- 0.2% of the cut off values)
- BMI 20.0kg/m2 or more, 35.0kg/m2 or less at visit 1
- Ages 18 to 65 years, inclusive - 18 years old or more and < 20 years old must have assent forms signed and dated by their parents or guardians
- Target Disease Exceptions History of T2DM In cases where the subject has a history of T2DM and has a documented history of being auto-antibody positive for GAD65, tyrosine phosphatase IA-2/IA-2 Beta, or Zinc Transporter 8 (ZnT8), or fasting c-peptide value below the lower limit of detection performed by local or central laborator, the subject will be eligible for screening
- Maturity onset diabetes of young (MODY), Pancreatic surgery, chronic pancreatitis, or other pancreatic disorders that could result in decreased Beta-cell capacity (eg, pancreatogenous diabetes)
- Any antihyperglycemic agent use, other than thiazolidinediones, or insulin, within 1 month prior to the screening visit. Use of thiazolidinediones within 6 months prior to the screening visit.
- History of DKA requiring medical intervention (eg, emergency room visit and/or hospitalization) within 1 month prior to the enrolment
- History of hospital admission for glycemic control (either hyperglycemia or hypoglycemia) within 1 month prior to the enrolment
- Malignancy within 5 years of the enrolment (with the exception of treated basal cell or treated squamous cell carcinoma)
- History of bladder cancer
- History of radiation therapy to the lower abdomen or pelvis at any time Unstable pre-proliferative and proliferative retinopathy (untreated or under treatment).
- Physical and Laboratory Test Findings Aspartate aminotransferase (AST) > 3x upper limit of normal (ULN) Alanine aminotransferase (ALT) > 3x ULN Serum total bilirubin (TB) > 2.0mg/dL (34.2 micro mol/L).
- Estimated GFR (eGFR) by the Japanese Society of Nephrology formula 60 mL/min/1.73m2 or less. Hemoglobin 11.0g/dL(110g/L) or less for men; hemoglobin 10.0g/dL(100g/L) or less for women.
