• Cardiac function: 12-lead electrocardiogram, QTc interval ≤ 480 ms, Echocardiogram, Left ventricular ejection fraction (LVEF) ≥ 50%.
• Thyroid function: Thyroid-stimulating hormone (TSH) ≤ 1 × ULN (if abnormal, FT3 and FT4 levels should be observed simultaneously. If FT3 and FT4 levels are normal, enrollment is allowed).
• Liver function grading for HCC patients: Child-Pugh score ≤ 7 points.
• Qualified patients (both male and female) with fertility must agree to use reliable contraceptive methods (hormonal or barrier methods or abstinence) together with their partners during the trial period and at least 6 months after the last administration.
• The patient must be informed of this study before the trial and voluntarily sign the written informed consent form.
