Iparomlimab and Tuvonralimab as Neoadjuvant Therapy for Resectable Hepatocellular Carcinoma With High Risk of Recurrence

Launched by TONGJI HOSPITAL · Apr 23, 2025

ClinConnect Summary

This clinical trial is exploring the use of two medications, iparomlimab and tuvonralimab, as a treatment before surgery for patients with a type of liver cancer called hepatocellular carcinoma (HCC) that can be removed but has a high chance of coming back after surgery. The goal is to see if this treatment can help patients live longer without the cancer returning, as well as improve overall survival after surgery.

To participate in this trial, individuals need to be between the ages of 18 and 75 and have a confirmed diagnosis of HCC that is suitable for surgery. They should not have received prior treatments for their cancer and need to meet specific health criteria, such as having proper liver and kidney function. Participants can expect to receive the study medications before their surgery and will be monitored closely throughout the process. This trial is not yet recruiting, so those interested should keep an eye out for updates about when they can join.

Eligibility criteria

• Inclusion Criteria:
• • Hepatocellular carcinoma is proven on biopsy or confirmed by the presence of radiological hallmarks, according to the American Association for the Study of Liver Diseases or European Association for the Study of the Liver guidelines.
• • Aged 18 to 75 years.
• • BCLC A/B, or BCLC C without extrahepatic metastasis.
• • Suitable for radical surgery after evaluation by the hepatobiliary tumor MDT expert group.
• • No distant metastasis confirmed by CT or MRI.
• • No prior systemic anti-tumor treatment for hepatocellular carcinoma before the first dose.
• • ECOG ≤ 2.
• • Child-Pugh ≤ 7.
• * Adequate organ and bone marrow function, with laboratory test values meeting the following requirements within 7 days prior to inclusion (no blood components, cell growth factors, albumin, or other intravenous or subcutaneous corrective treatment drugs are allowed within 14 days prior to obtaining laboratory tests):
• • 1. Complete blood count: Absolute Neutrophil Count (ANC) ≥1.5×10\^9/L; Platelet count (PLT) ≥75×10\^9/L; Hemoglobin (HGB) ≥9.0 g/dL.
• • 2. Liver function: Total Bilirubin (TBIL) ≤2×Upper Limit of Normal Value (ULN); Alanine Aminotransferase (ALT) and Aspartate Transferase (AST) ≤5×ULN; Serum albumin ≥28 g/L; Alkaline Phosphatase (ALP) ≤5×ULN.
• • C. Kidney function: Serum Creatinine (Cr) ≤ 1.5×ULN or Clearance of Creatinine (CCr) ≥50mL/min (Cockcroft-Gault formula); Urinalysis shows proteinuria \<2+; For subjects with baseline urinalysis showing proteinuria ≥2+, a 24-hour urine collection should be performed and 24-hour urinary protein quantification \<1g.
• • D. Coagulation function: International Normalized Ratio (INR) ≤2.3 or Prothrombin Time (PT) extension ≤6 seconds.
• * Meet the criteria for resectable HCC with High Risk of Recurrence:
• • 1. Multiple (≥2) tumors.
• • 2. Segmental portal vein invasion (Vp1/Vp2).
• • 3. CT/MRI imaging: gross classification: type II, III, IV.
• • Estimated life expectancy of ≥12 weeks.
• • Female subjects of childbearing age or male subjects whose sexual partners are of childbearing age need to take effective contraceptive measures during the entire treatment period and for 6 months after the last medication.
• • Signed written informed consent, and able to comply with the visit and related procedures stipulated in the protocol.
• Exclusion Criteria:
• • Histologically/cytologically confirmed fibrolamellar hepatocellular carcinoma, sarcomatoid hepatocellular carcinoma, cholangiocarcinoma, etc.
• • History of hepatic encephalopathy or liver transplantation.
• • Clinically symptomatic pleural effusion, ascites, or pericardial effusion requiring drainage. Subjects with only radiologically detected minimal pleural effusion, ascites, or pericardial effusion without symptoms can be enrolled.
• • Acute or chronic active hepatitis B or C infection, with hepatitis B virus (HBV) DNA \>2000IU/ml or 10\^4 copies/ml; hepatitis C virus (HCV) RNA \>10\^3 copies/ml; co-positive for hepatitis B surface antigen (HbsAg) and anti-HCV antibody. Subjects who meet the above criteria after antiviral treatment with nucleoside analogs can be enrolled.
• • History of esophageal or gastric variceal bleeding due to portal hypertension within the past 6 months. Subjects assessed by the investigator to be at high risk of bleeding.
• • Any life-threatening bleeding event within the past 3 months, including those requiring blood transfusion, surgery or local treatment, or continuous drug treatment.
• • History or current diagnosis of pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, drug-related pneumonia, severe impairment of lung function, and other lung diseases.
• • Active pulmonary tuberculosis, currently receiving anti-tuberculosis treatment, or received anti-tuberculosis treatment within 1 year prior to the first dose.
• • Active autoimmune disease requiring systemic treatment (such as disease-modifying drugs, corticosteroids, or immunosuppressants) within 2 years prior to the first dose. Replacement therapy (such as thyroxine, insulin, or physiological corticosteroids for adrenal or pituitary insufficiency, etc.) is allowed. History of primary immunodeficiency. Patients with only autoantibody positivity need to be confirmed by the investigator whether there is an autoimmune disease.
• • History of arterial or venous thromboembolic events within the past 6 months, including myocardial infarction, unstable angina, cerebrovascular accident or transient ischemic attack, pulmonary embolism, deep vein thrombosis, or any other serious thromboembolic events. Exceptions are made for thrombosis formation related to implanted venous infusion ports or catheters, or superficial vein thrombosis that has stabilized after routine anticoagulation treatment. Preventive use of low-dose low molecular weight heparin (such as enoxaparin 40 mg/day) is allowed.
• • Continuous use of aspirin (\>325 mg/day) or other known platelet function inhibitors such as clopidogrel or ticlopidine for 10 days within 2 weeks prior to the first dose.
• • Uncontrolled hypertension, with systolic blood pressure ≥150mmHg or diastolic blood pressure ≥100mmHg after optimal medical treatment, history of hypertensive crisis or hypertensive encephalopathy.
• • Major surgery (craniotomy, thoracotomy, or laparotomy) or unhealed wound, ulcer, or fracture within 4 weeks prior to the first dose. Minor surgical procedures or tissue biopsy within 7 days prior to the first dose, excluding venous puncture for the purpose of intravenous infusion, are excluded.
• • Uncontrolled/uncorrectable metabolic disorders or other non-malignant organ diseases or systemic diseases or secondary reactions to cancer, which can lead to higher medical risk and/or uncertainty in survival evaluation, or other conditions judged by the investigator to be unsuitable for enrollment.
• • History of gastrointestinal perforation and/or fistula within the previous 6 months, history of intestinal obstruction (including incomplete intestinal obstruction requiring parenteral nutrition), extensive bowel resection (partial colectomy or extensive small bowel resection complicated by chronic diarrhea), Crohn's disease, ulcerative colitis, or long-term chronic diarrhea.
