An Investigational Study of SHR6390 in Participants With Mild to Moderate Liver Impairment and Healthy Participants

A Single Dose, Open-label, Parallel Controlled Pharmacokinetic Study of SHR6390 in Participants With Mild to Moderate Liver Impairment and Healthy Participants

The purpose of this study is to investigate SHR6390 in participants with different levels of liver function

Inclusion Criteria:

-

• The informed consent is signed before the trial, and the content, process and possible adverse reactions are fully understood; Be able to complete the study according to the requirements of the test scheme;

• Chronic stable primary liver disease is necessary for patients with liver impairment, then patients with Grade-A/mild liver impairment (Child-Pugh score: 5-6) and Grade-B/moderate liver impairment (Child-Pugh score: 7-6) are assessed according to Child-Pugh classification;
• Provide documentary evidence of confirmed liver impairment;
• Patients who have stable medication regimen for liver impairment, complications and other concomitant diseases within at least 28 days before taking the experimental drug, and the medication does not need to be adjusted (including drug type, dosage or frequency) during the clinical trials; or those who do not use the drug;
• The function of vital organs meets the following criteria: Absolute neutrophil count (ANC) ≥ 1.0 × 109 / L (1000 / mm3); Platelet ≥ 75.0 × 109 / L (75000 / mm3); Hemoglobin (Hgb) ≥ 9.0 g / dL (90g / L); ALT and AST ≤ 5ULN; Creatinine clearance rate (CLcr) ≥ 60 mL / min; The corrected QTc interval (QTcF) ≤ 450 msec (male), ≤ 470 msec (female);
• In addition to liver impairment and complications, the investigator judged good condition according to the history inquiry, vital signs, physical examination, routine laboratory examination, 12-lead ECG, EEG, etc., and there was no other clinically significant abnormality;
• No family planning during the trial and within 6 months after the last administration of the trial drug, and voluntarily take effective contraceptive measures; Serum pregnancy test must be negative within 7 days before the experimental drug for women of childbearing age.
