Clinical Trial Summary

This is a single-center, randomized, double-blind, placebo-controlled, escalating single-dose and multiple-dose study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of HEC88473 injection in healthy subjects, obese subjects and subjects with type 2 diabetes mellitus (T2DM).

Description:

This study is divided into two parts, Part A is an escalating single-dose study in healthy subjects and obese subjects, and Part B is an escalating multiple-dose study in subjects with T2DM.

Eligibility

Inclusion Criteria:

Part A

1. Males or females, between 18 and 45 years of age, inclusive, at screening.

2. Body weight = 50 kg for males and body weight = 45 kg for females. 18=body mass index (BMI)<28 kg/m2 for nonobese subjects and 28=BMI=45 kg/m2 for obese subjects. Part B

1. Males or females, between 18 and 65 years of age, inclusive, at screening.

2. 24 kg/m2=BMI=35 kg/m2.

3. Subjects diagnosed with T2DM, newly diagnosed subjects at screening, or treated with diet and exercise alone within 3 months before screening and still have poor blood glucose control, or treated with a stable dose of metformin for = 3 months before screening.

4. 7.0%= HbA1c =10.5% at screening. Exclusion Criteria: Part A

1. Smoked more than 5 cigarettes per day within 3 months before the study.

2. Immunization with a live attenuated vaccine or coronavirus vaccination within 1 month prior to screening or planned vaccination during the course of the study.

3. Positive alcohol breath test result or positive urine drug screen.

4. Blood donation (> 300 mL) or massive blood loss (> 400 mL) within 3 months before screening. Part B

1. Have type 1 diabetes mellitus.

2. Have had =1 episode of severe hypoglycemia within 6 months before screening, or history of recurrent hypoglycemia (history of hypoglycemia more than 3 times in 3 months).

3. Have acute or chronic hepatitis, signs and symptoms of any other liver disease other than nonalcoholic fatty liver disease (NAFLD), or alanine aminotransferase (ALT) level >5 times the upper limit of the reference range at screening.

4. Have serum calcitonin =20 ng/L at screening.

5. Have a personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2; or have hereditary diseases that can easily induce MTC.

6. Fasted triglycerides > 5.7 mmol/L at screening. If the patient is on lipid-lowering therapies, doses must be stable for 30 days prior to screening.
