• Pregnant or lactating women or females with a positive pregnancy test prior to the first dose who have the potential for pregnancy.

Más betegség

• Presence of central nervous system metastasis or a history of brain metastasis.
• History of organ transplantation.
• History of surgery in the head, chest, or abdomen within the past six months.
• Marked thrombosis in the portal venous system or extensive cancer thrombus in the main portal vein.
• Ongoing active infection within 7 days after completion of systemic antibiotic therapy.
• Thrombotic or embolic events within the past 12 months, such as cerebrovascular accidents (including transient ischemic attacks), pulmonary embolism, or deep vein thrombosis.
• New York Heart Association (NYHA) class II or above congestive heart failure.
• Human immunodeficiency virus (HIV) infection or known acquired immunodeficiency syndrome (AIDS), positive syphilis serology, untreated active hepatitis (defined as HBV-DNA ≥ 10\^5 copies/ml; HCV-RNA higher than the lower limit of detection for the assay).
• Any active, known, or suspected autoimmune disease. Stable subjects not requiring systemic immunosuppressive therapy may be included, such as those with type 1 diabetes, hypothyroidism requiring only hormone replacement therapy, and skin diseases not requiring systemic treatment (e.g., vitiligo, psoriasis, and alopecia).
• Interstitial lung disease, non-infectious pneumonia, or uncontrolled systemic diseases (e.g., diabetes, hypertension, pulmonary fibrosis, and acute pneumonia).

Laborértékek

• Activated partial thromboplastin time (APTT) or prothrombin time (PT) exceeding 1.5 times the upper limit of normal (as per the normal values of the clinical trial research center), or evidence of bleeding tendency or history of bleeding within the two months prior to enrollment, regardless of severity.
• The investigator deems the subject inappropriate for participation in this clinical study due to any clinical or laboratory abnormalities or compliance issues.

Egyéb

• Severe psychological or mental abnormalities.
• Other reasons that the investigator considers unsuitable for enrollment.

• Patients aged 18 to 75 years (inclusive).

• Clinical or pathological diagnosis of hepatocellular carcinoma (HCC) that is unresectable initially or has recurred after surgery.
• HBV-DNA less than 1\*10\^5 copies/ml and undergoing antiviral therapy.
• ECOG performance status score of 0-1, without significant organ dysfunction.
• Child-Pugh score of 5-7.
• Spleen thickness \>4.0 cm.
• History of esophagogastric varices, red signs, or variceal bleeding with or without splenomegaly.
• Splenomegaly with WBC \<2.5 × 10\^9/L and PLT \<70 × 10\^9/L, or splenomegaly with WBC \<2.0 × 10\^9/L or PLT \<50 × 10\^9/L.
