- Personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia type 2.

- Diabetic acute metabolic complications or diabetic foot within 6 months before screening.
- Gastroparesis or other disorders associated with delayed gastric emptying, uncontrolled gastro-esophageal reflux disease, or any gastrointestinal condition that, in the investigator's opinion, increases risk after study drug administration.
