• BMI of 18.0 to 32.0 kg/m2
• Hemoglobin A1c ≤ 6.0%
• Female participants who are postmenopausal, confirmed by FSH test, or surgically sterile, confirmed by medical documentation, or agree to practice true abstinence
• Male participants agree to use contraception, or agree to practice true abstinence
• No clinically significant findings in physical examination, 12-lead electrocardiogram (ECG), vital sign measurements, laboratory tests, or medical/psychiatric history

• HbA1c ≥ 7.0% and ≤ 10.5%, and fasting plasma glucose ≤ 270 mg/dL
• Blood pressure (BP) with or without medication: Systolic BP ≤ 160 mmHg, AND Diastolic BP ≤ 100 mmHg
• Not taking any active treatment regimen

Exclusion Criteria:

• Concomitant participation in any investigational study of any nature
• Blood loss of non-physiological reasons ≥ 200 ml (i.e. trauma, blood collection, blood donation) within 2 months prior to the first dose of study drug, or plan to donate blood during this trial and within 1 month after the last dosing
• Unable to refrain from taking any non-metformin anti-diabetic medication including insulin within ≥ 3 months prior to the study treatment
• Serum calcitonin > 20 ng/L
• Clinically relevant acute or chronic medical conditions or diseases of the cardiovascular, gastrointestinal, hepatic, renal, endocrine, pulmonary, neurologic, psychiatric, immune or dermatologic systems
• Diagnosis of T1DM or secondary forms of diabetes
• Individual or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia 2 (MEN2), or suspected MTC
• History of pancreatitis
• Significant allergic reaction to active ingredients or excipients of the study drug.
