6. Participants with clinically significant abnormalities on ECG, or QTcF >450ms, or with a family history of long QT syndrome or a family history of Brugada syndrome.
7.

8. Participants who undergone major surgery, donated blood/bleeding profusely (> 400 mL) 12 weeks prior to randomization, donated blood/bleeding profusely (>200 mL) 4 weeks prior to randomization,or have a serious infection.
9. The average daily smoking are more than 5 cigarettes within 12 weeks prior to screening or unwilling to quit smoking during the study period.
10. Participants who may not complete the study for other reasons or should not be included in the study in the opinion of the investigator.
11. Known presence of a single genetic mutation, other diseases or medications causing obesity, including but not limited to hypothalamic obesity, pituitary obesity, hypothyroid obesity, Cushing's syndrome, insulinoma, growth hormone deficiency, acromegaly, pseudohypoparathyroidism, hypogonadism, or weight gain caused by increased non-fat content (e.g., edema)[Part C only]
