TIPS Plus Cadonilimab (a PD-1/CTLA-4 Bispecific Antibody) in Advanced Hepatocellular Carcinoma with Tumor Thrombosis-associated Portal Hypertension: a Prospective, Single-arm, Phase II Study
The purpose of this study is to evaluate the efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) plus Cadonilimab (a PD-1/CTLA-4 bispecific antibody) in advanced hepatocellular carcinoma (BCLC-C Stage) accompanied by tumor thrombosis-associated portal hypertension.
• The patient voluntarily joined the study and signed an informed consent form;
• ≥18 and ≤ 75 years old, both male and female;
• Clinically diagnosed or pathologically confirmed hepatocellular carcinoma, at least one measurable focus without local treatment (according to mRECIST requirements, the measurable focus spiral CT scan length ≥ 10 mm or enlargement Short diameter of lymph node ≥15 mm);
• Child-Pugh score ≤ 13 points;
• BCLC-C stage accompanied by tumor thrombosis-associated portal hypertension;
• Newly diagnosed patients who have not received targeted therapy or immunotherapy in the past;
• ECOG score: 0~1;
• Expected survival period ≥ 12 weeks;
• The functions of vital organs meet the following requirements (no blood components, cell growth factors and other corrective treatment drugs are allowed within 14 days before the first administration):
⁃ The absolute count of neutrophils≥1.5×109/L; Platelet ≥50×109/L; Hemoglobin ≥60 g/L; Serum albumin ≥28 g/L; Thyroid-stimulating hormone (TSH)≤1×ULN (if abnormal, the levels of FT3 and FT4 should be examined at the same time, if the levels of FT3 and FT4 are normal, they can be included in the group); Bilirubin≤2×ULN (within 7 days before the first administration); ALT and AST ≤5×ULN (within 7 days before the first dose); Serum creatinine≤1.5×ULN;
⁃ Non-surgical sterilization or female patients of childbearing age need to use a medically approved contraceptive method (such as an intrauterine device, contraceptive, or condom) during the study treatment period and within 3 months after the end of the study treatment period; Female patients of childbearing age who undergo surgical sterilization must be negative in serum or urine HCG within 72 hours before enrollment in the study; and must be non-lactating; for male patients whose partners are women of childbearing age, at the last time use effective methods for contraception within 3 months.
