Healthy as determined by the investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests, and Electrocardiograms (ECGs) on day -1 (Part A) and day -1 (Part B) and screening
-
Body Mass Index must be between 18 and < 25 kg/m^2 for healthy participants and between ≥ 25 and ≤ 32.0 kg/m^2 for otherwise healthy participants with obesity
-
Have a stable body weight (less than 5 kg self-reported change during the previous 8 weeks) prior to screening
-
Willing to maintain current general diet and physical activity regimen, except for the physical activity in the 72 hours before each blood sample collection for the clinical laboratory analysis, which should not be strenuous
- Malignancy except non-melanoma skin cancers, cervical or breast ductal carcinoma in situ within the last 5 years
- History or clinical evidence of diabetes mellitus, including a fasting glucose ≥ 125 mg/dl (6.9 mmol/L) and/or HbA1c ≥ 6.5%
- Triglycerides ≥ 5.65 mmol/L (ie, 500 mg/dL) at screening
- Hepatic liver enzymes alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, or total bilirubin levels > 1.5 times the upper limit of normal (ULN) at screening. Participants with suspected or diagnosed Gilbert's disease will be excluded from the study.
- History or clinical evidence of bleeding diathesis or any coagulation disorder, including prothrombin time (PT), activated partial thromboplastin time (APTT), International normalized ratio (INR) or platelet count outside of the laboratory's normal reference range unless interpreted as not clinically significant by the investigator in consultation with the medical monitor at screening.
- History of gastrointestinal (GI) abnormality that could affect GI motility (including small bowel or colonic resection, inflammatory bowel disease, irritable bowel disease, and colon or GI tract cancer)

- A corrected QT interval at screening of > 450 msec in males or > 470 msec in females or history of long QT syndrome
- History of coronary artery disease or congestive heart failure
- Participants with a history of renal impairment or renal disease and/or estimated glomerular filtration rate (eGFR) ≤ 60 mL/min/1.73 m^2
- Obesity induced by other endocrinologic disorders (eg, Cushing's Syndrome)
- Previous surgical treatment for obesity (excluding liposuction if performed > 1 year before trial entry)
- History of major depressive disorder
- History of other severe psychiatric disorders, eg, schizophrenia, bipolar disorder
- A patient health questionnaire-9 score of ≥ 10
- Participant has a history or evidence of suicidal ideation (severity of 3, 4 or 5) or any suicidal behavior based on an assessment with the Columbia suicide severity rating scale at screening
- Surgery scheduled for the trial duration period, except for minor surgical procedures, with consultation by the Amgen Medical Monitor
- Positive results for human immunodeficiency virus (HIV) antibodies, hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), or hepatitis C virus ribonucleic acid (RNA). For hepatitis C, hepatitis C antibody (HepCAb) testing is done at screening, followed by hepatitis C virus RNA by polymerase chain reaction (PCR) if hepatitis C antibody is positive
- Participant has systolic blood pressure ≥ 150 mm Hg or diastolic blood pressure ≥ 90 mm Hg at screening, and on day -1. For each visit, if the initial blood pressure is elevated, the reading may be repeated once at least 15 minutes later and the lower of the 2 readings may be used

Group Intervention Description Part A: Single Ascending Dose Cohorts Placebo Participants in 4 cohorts will receive either AMG 786 or placebo in Single Ascending Doses. Part B: Multiple Ascending Dose Cohorts Placebo Participants in 4 cohorts will receive either AMG 786 or placebo in Multiple Ascending Doses. Part A: Single Ascending Dose Cohorts AMG 786 Participants in 4 cohorts will receive either AMG 786 or placebo in Single Ascending Doses. Part A: Food Effect Cohort Placebo Participants in the food effect cohort (FEC) will receive 1 of 2 AMG 786 in 1 of two sequences. Participants in Sequence 1 will receive a dose of AMG 786 on day 1 under fed conditions followed by a 10-day washout period and another dose of AMG 786 on day 11 under fasted conditions. Participants in Sequence 2 in the FEC cohort will receive the first dose on day 1 under fasted conditions and the second dose on day 11 under fed conditions. Part B: Multiple Ascending Dose Cohorts AMG 786 Participants in 4 cohorts will receive either AMG 786 or placebo in Multiple Ascending Doses. Part A: Food Effect Cohort AMG 786 Participants in the food effect cohort (FEC) will receive 1 of 2 AMG 786 in 1 of two sequences. Participants in Sequence 1 will receive a dose of AMG 786 on day 1 under fed conditions followed by a 10-day washout period and another dose of AMG 786 on day 11 under fasted conditions. Participants in Sequence 2 in the FEC cohort will receive the first dose on day 1 under fasted conditions and the second dose on day 11 under fed conditions.
