• 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, practiced and was willing to continue to practice appropriate birth control during the entire duration of the study

6. Had a physical examination with no clinically significant abnormalities as judged by the investigator

7. Ability to understand and willingness to adhere to protocol requirements

8. If on chronic thyroid pharmacologic therapy, the dose must have been 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

1. Had a clinically significant medical condition that could potentially affect study participation and/or personal well-being, as judged by the investigator, including but not limited to the following conditions:

• Hepatic disease
• Renal disease
• Gastrointestinal disease
• Endocrine disorder except diabetes
• Cardiovascular disease
• Central nervous system diseases
• Psychiatric or neurological disorders
• Organ transplantation
• Chronic or acute infection
• Orthostatic hypotension, fainting spells or blackouts
• Allergy or hypersensitivity

2. Had any chronic disease requiring medication that was adjusted in the past 90 days (subjects could take acute intermittent over-the-counter medications such as Tylenol, if needed)

3. Had 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)

4. Had major surgery of any kind within 6 months of Visit 1 (Screening)

5. Had received a blood transfusion within 6 months of Visit 1 (Screening)

6. Had a history of >5 kg weight change within 3 months of Visit 1 (Screening)

7. Had clinical laboratory test (clinical chemistry, hematology, or urinalysis) abnormalities other than those expected in subjects with type 2 diabetes and judged by the investigator to be clinically significant at Visit 1 (Screening)

8. Had a physical, psychological, or historical finding that, in the investigator's opinion, would make the subject unsuitable for the study

9. Abused drugs or alcohol or had a history of abuse that in the investigator's opinion would cause the individual to be noncompliant with study procedures
