- Subject has provided written informed consent - Men and women between the ages of 18 and 65, inclusive at the time of randomization - Women must be of documented non-reproductive potential (ie, postmenopausal [see definition below]; OR history of hysterectomy; OR history of bilateral tubal ligation; OR history of bilateral oophorectomy). - Diagnosed with type 2 diabetes - HbA1c ≥ 6.5% and ≤ 10% - Fasting C-peptide value ≥ 0.8 ng/mL - Men must agree for the duration of the study and continuing for 4 weeks after the dose of study drug, to practice a highly effective method of birth control. Highly effective methods of birth control include sexual abstinence, vasectomy or a condom with spermicide (men) in combination with either barrier methods, hormonal birth control or IUD (women). - Men must agree to not donate sperm for the duration of the study and continuing for 4 weeks after the dose of study drug. - Body mass index between ≥ 25.0 kg/m2 and ≤ 40.0 kg/m2 at screening - Negative screening test for alcohol and potential drugs of abuse at screening and day -2, unless medication is prescribed by a physician and approved by the principal investigator and Amgen medical monitor

- Men with partners who are pregnant at the time of screening or men with partners who plan to become pregnant during the study - Women who are pregnant or breastfeeding History or evidence of a clinically significant disorder, condition or disease that, in the opinion of the principal investigator or Amgen medical monitor would pose a risk to subject safety or interfere with the study evaluation, procedures or completion - Evidence or history at screening of diabetic complications with significant end-organ damage, eg, proliferative retinopathy and/or macular edema, creatinine clearance < 60 mL/min/1.73m2 (calculated using the Modification of Diet in Renal Disease formula), or macroalbuminuria (ie, ≥ +1 proteinuria on urinalysis), diabetic neuropathy complicated by neuropathic ulcers, or severe autonomic neuropathy with gastroparesis, chronic diarrhea, or hypoglycemic unawareness - Significant cardiac disease, including but not limited to evidence or history of coronary artery disease, unstable angina, congestive heart failure, known arrhythmias of ventricular etiology, unexplained syncope or syncope/seizures related to arrhythmia - Positive for human immunodeficiency virus (HIV) antibodies, hepatitis B surface antigen (Hbs Ag), or hepatitis C virus antibodies - An unstable medical condition, defined as having been hospitalized within 28 days before day -1, major surgery within 6 months before day -1, or otherwise unstable in the judgment of the investigator (eg, risk of complications or adverse events unrelated to study participation)
