Hepatic Insufficiency (MeSH ID: D048550)
Conditions
Brief summary
This study is a single-center, non-randomized, open-label, parallel, single-dose study to evaluate the PK profile and safety of MY008211A Tablets in subjects with hepatic impairment.
Detailed description
This study is a single-center, non-randomized, open-label, parallel, single-dose study to evaluate the PK profile and safety of MY008211A Tablets in subjects with hepatic impairment. It is planned to enroll 24 subjects, male or female. A total of 3 treatment groups will be set up: normal hepatic function group, mild hepatic impairment (Child-Pugh A) group, moderate hepatic impairment (Child-Pugh B) group, with 8 subjects in each group. Each subject will take a single oral dose of 400 mg MY008211A Tablets under fasting conditions. This study will first enroll subjects in Group A (mild hepatic impairment) and Group B (moderate hepatic impairment). Age, gender and body weight will not be matched between subjects in Groups A and B; after enrollment for Groups A and B is completed, subjects will be enrolled in Group C (normal hepatic function) as control subjects matched with the hepatic impairment subjects (Group A + Group B): Subjects who sign the informed consent form (ICF) will be screened according to the inclusion/exclusion criteria. Eligible subjects will be admitted to the Clinical Research Unit (CRU) on Day -1 (D-1). On D1, they will take a single oral dose of 400 mg MY008211A Tablets under fasting conditions and will be discharged after completing the observations and drop-out examinations on D4. They will receive a telephone follow-up on D11. During the study, sample collection, recording of adverse events (AEs), concomitant medication/non-drug therapy, physical examination, vital signs, ECG, and clinical laboratory tests will be performed according to the protocol requirements.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Cmax | up to 12 weeks | maximum concentration |
| AUC0-last | up to 12 weeks | area under the plasma concentration-time curve from 0 to the last quantifiable time point |
| AUC0-inf | up to 12 weeks | area under the plasma concentration-time curve from 0 to infinity |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Tmax | up to 12 weeks | time to reach maximum concentration |
| CL/F | up to 12 weeks | apparent clearance |
| Vz/F | up to 12 weeks | apparent volume of distribution |
| t1/2 | up to 12 weeks | terminal half-life |
| body temperature | up to 12 weeks | Measure the body temperature of the subjects, using degrees Celsius as the unit. |
| IU/L or mIU/mL of HCG in the blood of reproductive-aged women | up to 12 weeks | The blood human chorionic gonadotropin (HCG) pregnancy test will measure the concentration of HCG in the blood of reproductive-aged women to determine if they are pregnant. The units in the report will be presented in IU/L (international units per liter) and/or mIU/mL. |
| 12-lead ECG | up to 12 weeks | Evaluate QT interval, PR interval, etc. |
| adverse events and serious adverse events | up to 12 weeks | — |
| Pulse | up to 12 weeks | Measure the pulse of the subjects, expressing it in units of beats per minute. |
| Blood pressure | up to 12 weeks | Measure the systolic and diastolic blood pressure of the subjects, with the unit of mm/hg. |
