5. Has a calculated creatinine clearance >60 mL/min at Screening and Check-in (Day -2).

Exclusion Criteria:

Part 1:

1. Has Screening or Check-in (Day -2) laboratory values of serum creatinine ≥1.5 mg/dL for males or ≥1.4 mg/dL [females] or abnormal creatinine clearance.

2. Has a history of T1DM, hypoglycemia unawareness, diabetic ketoacidosis, or hyperosmolar coma.

3. Has a history of any clinically significant retinopathy, which is defined as more than moderate nonproliferative diabetic retinopathy or any stage of proliferative diabetic retinopathy or any history of laser-treated retinopathy.

4. Has received any antihyperglycemic medication with the exception of metformin within the previous 12 weeks of Check-in (Day -2) or the subject has changed the dose of metformin within the previous 8 weeks of Screening.

2. Has received TAK-648 in a previous clinical study or as a therapeutic agent.

3. Has any significant medical histories or currently uncontrolled clinical conditions, which may not be safe for participants to participate in the study, may impact the ability of the participant to participate in the study, or may potentially confound the study results. The concerned significant medical histories and uncontrolled clinical conditions include (may not be limited to) cardiovascular (such as ischemic heart disease, heart failure, cardiomyopathy, clinically significant arrhythmia, uncontrolled or unstable blood pressure), central nervous system, hepatic or hematopoietic disease(s), renal dysfunction, metabolic or endocrine dysfunction, pulmonary diseases including serious allergy and asthma hypoxemia, seizures, or allergic skin rash.

5. Has diagnosis of major depression, bipolar disorder or anxiety disorders, or has a risk of anxiety, depression, or insomnia according to the investigator's clinical judgment per HAM-D17 at Screening or has received any medication to treat any psychological disorders within 1 year.
