NCT ID: NCT06938529

Last Updated: 2025-08-14

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 24 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2025-04-18
• Study Completion Date: 2025-07-25

Brief Summary

This is an open-label, non-randomized study to assess how VCT220 is absorbed, distributed, metabolized, and eliminated after a single oral dose. The study includes three groups: subjects with mild hepatic impairment (Child-Pugh Class A), subjects with moderate hepatic impairment (Child-Pugh Class B), and healthy subjects matched by gender, age, and body mass index (BMI). It will also explore the relationship between baseline liver function measures and the pharmacokinetic (PK) parameters of VCT220, to support appropriate dosing recommendations for patients with liver impairment.

2. Subjects must be between 18 and 75 years old (inclusive), of any sex;

4. Subjects and their partners must agree to have no plans for pregnancy or sperm/egg donation from the signing of the informed consent form until 6 months after the last administration of the study drug, and must voluntarily use effective contraception.

1. Subjects must have hepatic impairment caused by a primary liver disease, classified as Child-Pugh Class A (score 5-6) or Class B (score 7-9) at screening, and must not have used albumin within 14 days prior to screening. The hepatic impairment must be confirmed as stable (≥1 month) based on medical history, physical examination, laboratory tests, or imaging studies;

2. Subjects must not have taken any medications within 1 week prior to screening, or, if long-term treatment for hepatic impairment and/or other comorbidities is necessary, must have been on a stable regimen for at least 4 weeks prior to screening (stable medication use to be determined by the investigator, excluding prohibited medications per protocol).

Exclusion Criteria

• Known allergy to any component of the investigational drug, similar drugs (GLP-1 receptor agonists), or their excipients, a history of allergic constitution (multiple drug and food allergies), or a history of allergic diseases (such as asthma, urticaria, eczema, etc.);
• A history of hypoglycemia;
• Personal or family history of medullary thyroid carcinoma (MTC) or type 2 multiple endocrine neoplasia syndrome (MEN2), or suspected MTC as judged by the investigator;
• A history of pancreatitis (chronic or acute pancreatitis);
• A history of malignant tumors or malignancy within the past 5 years (excluding stable liver cancer post-surgery for ≥2 years, treated and non-recurrent skin non-melanoma cancers, and removed cervical intraepithelial neoplasia);
• Severe infection, trauma, gastrointestinal surgery, or other major surgeries within the 4 weeks prior to screening;
• Clinically significant abnormalities on a 12-lead electrocardiogram (ECG), such as tachycardia/bradycardia requiring medication, second to third-degree atrioventricular block, QTcF interval prolongation (QTcF >470 ms in males, >480 ms in females) as per Fridericia's formula, or other clinically significant abnormalities as determined by the clinician;
• Estimated glomerular filtration rate (eGFR) <60 ml/min/1.73m², calculated using the Modification of Diet in Renal Disease (MDRD) formula;

• Took any medication (including traditional Chinese medicine, vitamins, supplements) within 14 days prior to dosing (or 5 half-lives, whichever is longer), except for stable medication use in subjects with hepatic impairment;
• Participated in another clinical trial and received investigational drugs or medical devices within 1 month prior to screening, with the last dose date of the clinical study as the baseline (if the clinical trial drug has a long half-life, there should be at least a 5 half-life gap between this study and the previous one);
