Who can join

Age: 18 and older. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Voluntarily sign the informed consent form before any study-related activities commence, demonstrate an understanding of the trial procedures and methodology, and be willing to strictly adhere to the clinical trial protocol for study completion;
• Subjects (including their partners) must agree to have no plans for conception from screening until 6 months after the last dose of the investigational drug and to voluntarily practice effective contraception during this period;
• Aged 18 to 70 years (inclusive) at the time of signing informed consent, either male or female. For the elderly group, subjects must be aged 65 years or older (inclusive);
• Body mass index (BMI) between 18 and 32 kg/m² (inclusive);
• Subjects in the healthy group should be matched as closely as possible to those in the hepatic impairment, renal impairment, and elderly groups in terms of gender and weight, and additionally matched for age with the hepatic and renal impairment groups;
• Subjects in the hepatic impairment group must also meet all of the following additional criteria:
• Subjects with chronic liver injury due to primary liver diseases (e.g., hepatitis B, hepatitis C, autoimmune hepatitis, alcoholic liver disease, etc.), classified as Child-Pugh Grade B hepatic insufficiency; Clinically diagnosed cirrhosis; eGFR > 59 mL/min; Subjects are either those with a stable concomitant medication regimen (for hepatic impairment/complications/other diseases) for ≥2 weeks pre-dose not requiring anticipated adjustment (excluding, e.g., diuretics/insulin), or those not on such medications;
• Subjects in the renal impairment group must also meet all of the following additional criteria:
• Diagnosed with chronic kidney disease (CKD), defined as the presence of any marker of kidney damage or GFR < 60 mL/min for more than 3 months (evidence may include outpatient records, inpatient records, or laboratory reports); GFR must meet the following criteria: Moderate renal impairment (CKD Stage 3): 30-59 mL/min (inclusive); Severe renal impairment (CKD Stage 4): 15-29 mL/min (inclusive); Note: Staging will be determined solely based on the second scheduled GFR measurement during the screening period; Renal function must be stable, defined as meeting either of the following criteria based on two GFR measurements taken prior to dosing (with at least a 3-day interval between measurements): Both results fall within the same CKD stage; or the fluctuation between the two GFR results is <10% (calculated as: [(Second result - First result) / First result] × 100%).

You may not qualify if…

• Subjects with a history of hypersensitivity or allergic constitution (including severe drug allergies or drug hypersensitivity reactions), or with a known allergy to the investigational drug or any of its excipients;
• QTcF (male) > 470 ms, QTcF (female) > 480 ms;
• Uncontrolled hypertension, defined as systolic blood pressure ≥ 160 mmHg or diastolic blood pressure ≥ 100 mmHg despite antihypertensive therapy. This criterion does not apply to subjects in the healthy group;
• History of dysphagia or any gastrointestinal disorder that may affect drug absorption, including frequent nausea or vomiting due to any etiology;
• History of severe infection, trauma, gastrointestinal surgery, or other major surgery within 4 weeks prior to screening;
• Receipt of any vaccine within 14 days prior to screening, or intention to receive any vaccination during the course of the study;
• Donation or loss of blood ≥ 400 mL within 3 months prior to screening, or intention to donate blood during the study;
• Use of moderate or strong CYP3A4 inhibitors/inducers within 2 weeks prior to screening, or planned concomitant use during the study; or use of CYP3A4-sensitive substrates within 2 weeks prior to screening or planned use during the study;
• Use of proton pump inhibitors (PPIs, e.g., rabeprazole, pantoprazole, esomeprazole) within 2 weeks prior to screening or planned concomitant use during the study; medications known to affect serum creatinine clearance (e.g., calcium dobesilate, trimethoprim/sulfamethoxazole, cimetidine); drugs prone to cause liver injury (e.g., non steroidal anti inflammatory drugs, antibiotics, antituberculosis agents, antifungals, glucocorticoids); or drugs with high plasma protein binding (e.g., warfarin, dicoumarol, diazepam, phenylbutazone, digitoxin);
• Consumption of special diets (including pitaya, mango, pomelo, and/or xanthine containing foods such as chocolate) within 2 weeks prior to dosing, and/or habitual excessive intake of tea, coffee, grapefruit/grapefruit juice, or caffeinated beverages (average >8 cups per day, 200 mL per cup);
• History of excessive alcohol consumption, defined as >14 units per week on average, within the 3 months preceding screening (where 1 alcohol unit equals 360 mL of beer, 45 mL of 40% distilled spirits, or 150 mL of wine);
• Positive result on alcohol breath test or urine drug screening at screening;
• Average cigarette consumption of ≥10 cigarettes per day within 3 months prior to screening;
• History of drug abuse or substance misuse;
• Pregnant or lactating women, or women of childbearing potential with a positive pregnancy test;
• Intolerance to venipuncture or history of needle/phobia syncope;
• Use of any investigational drug within 3 months prior to screening or planned participation in another clinical trial during this study;
• Other conditions deemed by the investigator to compromise the subject's suitability for the study;
• Healthy Subjects will be excluded if they meet any of the following criteria:
• History of hepatic impairment or renal impairment;
• Any clinically significant active or chronic disease affecting major organ systems (e.g., circulatory, endocrine, neurological, digestive, respiratory, hematologic, immunologic, psychiatric, or metabolic systems) at screening, or any other medical condition that could potentially confound the interpretation of study outcomes;
• Clinically significant abnormalities (as judged by the investigator) in physical examination, vital signs, laboratory tests, 12 lead ECG, abdominal ultrasound, or chest X ray;
• Positive screening result for any of the following: hepatitis B surface antigen (HBsAg), hepatitis C antibody (HCV Ab), HIV antigen/antibody, or syphilis antibody;
• Administration of any prescription medication, non prescription drug, vitamin supplement, or herbal preparation within 14 days prior to screening;
