Is male, or is female and meets all of the following criteria: 1. Not breastfeeding 2. Negative pregnancy test result (human chorionic gonadotropin, beta subunit [βhCG]) at Visit 1 (not applicable to hysterectomized females) 3. If of child bearing potential (including perimenopausal women who have had a menstrual period within 1 year), must practice and be willing to continue to practice appropriate birth control (defined as a method which results in a low failure rate, i.e., less than 1% per year, when used consistently and correctly, such as implants, injectables, hormonal contraceptives, intrauterine contraceptive devices (IUD), sexual abstinence, tubal ligation or occlusion, condom with spermicide or a vasectomized partner) during the entire duration of the study. 8. Has a physical examination and ECG with no clinically significant abnormalities as judged by the investigator at Visit 1. 9. Has no clinically significant laboratory test values (clinical chemistry, hematology, urinalysis) other than those expected in subjects with diabetes as judged by the investigator at Visit 1. 10. Either is not treated with or has been on a stable treatment regimen with any of the following medications for a minimum of 2 months prior to Visit 1: 1. Hormone replacement therapy (female subjects) 2. Oral contraceptives (female subjects) 3. Antihypertensive agents 4. Lipid-lowering agents 5. Thyroid replacement therapy 6. Antidepressant agents 7.

Has known hypersensitivity, intolerability, or allergies to metformin HCl or any component of study treatment. 4. Has physical, psychological, or historical finding that, in the investigator's opinion, would make the subject unsuitable for the study. 5. 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. 6.

Has been treated, is currently being treated, or is expected to require or undergo treatment with any of the following excluded medications: 1.
