Eligibility Criteria
Inclusion Criteria:

- Has serum creatinine below the upper limit of normal at Visit 1 and an estimated creatinine clearance above 80 using the Crockroft and Gault equation (CrCl = [(140 - age) x body weight in kg] / (serum creatinine x 72) x (0.85 for females) [ref. 3].
- Has a body mass index (BMI) of 25.0 to 40.0 kg/m^2 (inclusive) at Screening.
Is male, or is female and meets all of the following criteria:
- Not breastfeeding
- Negative pregnancy test result (human chorionic gonadotropin, beta subunit) at Visit 1 (Screening) (not applicable to hysterectomized females)
- Surgically sterile, postmenopausal, or if of childbearing potential, must practice and be willing to continue to practice appropriate birth control during the entire duration of the study
- Has a physical examination with no clinically significant abnormalities as judged by the investigator.
- Ability to understand and willingness to adhere to protocol requirements.
- If on chronic thyroid pharmacologic therapy, the dose must be stable for at least 3 months prior to Visit 1 (Screening), and must have thyroid-stimulating hormone (TSH) test result in normal range at Visit 1 (Screening).
Exclusion Criteria:

- Hepatic disease
- Renal disease
- Gastrointestinal disease
- Endocrine disorder except diabetes
- Cardiovascular disease
- Seizure disorder
- Organ transplantation
- Chronic infection
- Has any chronic disease requiring medication that has been adjusted in the past 90 days (subjects may take acute intermittent over-the-counter medications such as Tylenol, if needed).
- Has any drug treatment that affects gastric pH (prescription or over-the-counter), including any antacids or medications such as Rolaids or Pepcid within 2 days of Visit 1 (Screening).
- Has had major surgery of any kind within 6 months of Visit 1 (Screening).
- Has received a blood transfusion within 6 months of Visit 1 (Screening).
- Has a history of >5 kg weight change within 3 months of Visit 1 (Screening).
- Has clinical laboratory test (clinical chemistry, hematology, or urinalysis) abnormalities other than those expected in subjects with diabetes and judged by the investigator to be clinically significant at Visit 1 (Screening).
- Has physical, psychological, or historical finding that, in the investigator's opinion, would make the subject unsuitable for the study.
- Currently abuses drugs or alcohol or has a history of abuse that in the investigator's opinion would cause the individual to be noncompliant with study procedures.
- Has donated blood within 2 months of Visit 1 (Screening) or is planning to donate blood during the study.
- Has used insulin within 3 months of Visit 1 (Screening).
- Has received GLP-1 receptor agonists and/or thiazolidinedione treatment within 6 months of Visit 1 (Screening).
- Has known intolerance to metformin.
- Has received any investigational drug within 1 month (or five half-lives of the investigational drug, whichever is greater) of Visit 1 (Screening).
- Has known allergies or hypersensitivity to any component of study treatment.
