glucose monitoring.
- The subjects were able to communicate well with the researchers and complete the study
according to the protocol.
Exclusion Criteria:

relatives refer to persons with consanguineous or legal relationships, including

treatment (such as surgery, excessive diet and exercise therapy) that leads to
weight instability.
5. Participated in clinical trials of any drug or medical device in the past 3
months.
6. Other drugs that may affect blood glucose metabolism have been used in the past 8
weeks, including growth hormone treatment, and long-term or repeated intermittent
systemic glucocorticoids (intravenous, oral or intra-articular administration for
more than 2 weeks or repeated courses, except inhalation or local external use),

hypotension, diabetic diarrhea or gastroparesis.
6. Have a history of acute or chronic pancreatitis.
7. Ketoacidosis, diabetic acidosis or hyperosmolar nonketotic coma have occurred in
the past 6 months and need to be hospitalized.
8. In the past 6 months, serious hypoglycemic events with unknown causes (need other
people's help to recover); or frequent hypoglycemia: for example, more than two
hypoglycemic events (blood glucose = 3.9mmol / L) occurred in the first month
before screening.
9. Any endocrine system disease related to blood glucose (such as hyperthyroidism,
acromegaly, Cushing's syndrome), immune system disease or other diseases that are
unstable or need treatment are not suitable for the study according to the
judgment of researchers.
10. Have other diseases that affect glucose metabolism or are taking drugs that
significantly affect glucose metabolism.
11. Severe trauma or acute infection that may affect blood glucose control has
occurred in the past month.
12. Suffer from serious cardiovascular disease, respiratory system disease,
gastrointestinal disease, liver dysfunction, renal dysfunction, endocrine disease
(except diabetes), blood system disease, nervous system disease, and the disease
status can significantly change the absorption, distribution, metabolism and
excretion of the test drug, or taking the test drug will increase the risk of the
subject or affect the analysis of the research results.
13. There are any types of malignant tumors (whether cured or not).
14. A history of diseases that may cause hemolysis or red blood cell instability that
affect HbA1c detection, such as hemoglobinopathy (such as sickle cell anemia or
thalassemia, ferriblastic anemia).
15. History of alcohol and drug abuse. Drink more than 21 units (male) or 14 units
(female) of alcohol per week (1 unit is about 360 ml of beer or 45 ml of spirits
or 150 ml of wine with 40% alcohol).
16. There are mental or nervous system diseases, unwillingness to communicate or
language barriers, and insufficient understanding and cooperation.
- There is any laboratory inspection index meeting the following standards at screening
or random:

atrioventricular block, or corrected qtcb > 450ms (male) or > 470ms (female).
2. eGFR<60ml/(min•1.73m2)?

hepatitis C, HIV and Treponema pallidum.

contraceptive methods during the study and at least one month after the last
administration.
