A Study of HDM1002 in Subjects With And Without Varying Degrees Of Hepatic Impairement

Inclusion criteria

• Age and Sex: Chinese subjects aged 18-70 years (inclusive) at screening, regardless of gender. The normal hepatic function group and hepatic impairment group must be age-matched within ±10 years, with gender matching as close as possible (±1 subject per gender).
• Body Weight and Body Mass Index (BMI): At screening, male subjects must weigh ≥50.0 kg, and female subjects ≥40.0 kg, with a BMI ranging from 19.0 to 32.0 kg/m² (inclusive).The normal hepatic function group and hepatic impairment group must be weight-matched within ±10 kg.

Exclusion criteria

• History or family history of medullary thyroid carcinoma, thyroid C-cell hyperplasia, or multiple endocrine neoplasia type 2; or serum calcitonin ≥50 ng/L at screening.
• History of chronic pancreatitis or an episode of acute pancreatitis within 3 months prior to signing the informed consent form (ICF).
• History of acute gallbladder disease within 3 months prior to signing the ICF.
• History of Malignancy: Diagnosis of any malignancy within 5 years prior to ICF signing (except basal cell carcinoma treated with curative intent and deemed cured).
• Severe Systemic Diseases: History of severe cardiovascular, neuropsychiatric, gastrointestinal, respiratory, urinary, endocrine, or other systemic diseases (e.g., acute myocardial infarction, severe depression, gastric ulcer, uremia) within 1 year prior to ICF signing.
• Conditions Affecting Drug Pharmacokinetics: Presence of dysphagia or any condition that, on the investigator's judgment, may impact drug absorption, distribution, metabolism, or excretion (e.g., active inflammatory bowel disease, gastrectomy, intestinal resection) at screening.
• Severe Hypoglycemia: Episode of severe hypoglycemia within 3 months prior to screening.
• Allergy or Intolerance: History of allergic diseases (e.g., asthma, urticaria, eczematous dermatitis) or known intolerance/allergy to glucagon-like peptide-1 receptor (GLP-1R) agonists.
• Hepatic Function Normal Group Exclusions:a) History of chronic liver disease, including hepatitis, hepatitis B, or hepatitis C, or positive for hepatitis B surface antigen (HBsAg) or hepatitis C virus antibody (anti-HCV) at screening.b) Positive Treponema pallidum antibody.c) Use of any medication within 28 days or 5 elimination half-lives (whichever is longer) prior to the first study drug administration.
• Hepatic Impairment Group Exclusions:a) Hepatocellular carcinoma, hepatorenal syndrome, or limited life expectancy (defined as <1 year for the hepatic impairment cohort).b) Cirrhosis complications (e.g., gastrointestinal bleeding, severe hypoglycemia) within 3 months prior to screening.c) Use of any medication within 7 days or 5 half-lives (whichever is longer) prior to the first study drug administration that may affect HDM1002 pharmacokinetics (PK).
