Benmelstobart Plus Anlotinib Combined With SBRT for Patients With Hepatocellular Carcinoma Failing First-Line Targeted Therapy

Starting soon · Phase 2

Conditions studied: Hepatocellular Carcinoma (HCC), First-line Targeted Therapy Failure, Oligometastatic Hepatocellular Carcinoma, Benmelstobart, Anlotinib, SBRT

In brief

This prospective, single-arm, multicenter Phase II clinical trial aims to evaluate the efficacy and safety of Benmelstobart plus anlotinib combined with SBRT in patients with oligometastatic hepatocellular carcinoma who have failed first-line targeted therapy. Key study questions include: What is the progression-free survival (PFS) for patients treated with this regimen? How do the objective response rate (ORR), disease control rate (DCR), and overall survival (OS) compare? What are the safety and tolerability profiles of the combination therapy? Eligible subjects (after signing informed consent) will receive anlotinib 10mg on days 1-14 every 3 weeks + Benmelstobart 1200mg on day 1 every 3 weeks + SBRT. Treatment cycles will be 3 weeks long, continuing until a protocol-specified treatment discontinuation event occurs. Following treatment completion, subjects will undergo post-treatment safety follow-up and survival monitoring, with tumor progression monitoring conducted post-treatment.

• At least one measurable lesion (the long diameter of the measurable lesion on enhanced spiral CT or enhanced MR Scan >=10mm or the short diameter of the enlarged lymph node >=15mm according to RECISTv1.1; a lesion that has been treated with previous radiotherapy can be considered as a target lesion after definite progression according to RECISTv1.1 criteria);
• The following laboratory tests performed within 7 days before the first dose of medication confirmed that the patient's bone marrow, liver and kidney function met the following requirements for study participation: 1) hemoglobin >=80 g/L (which can be maintained or exceeded by transfusion); 2) absolute neutrophil count (ANC) >=1.5×10\^9; 3) platelet count >=50×10\^9/mm3; 4) Total bilirubin <=1.5 times upper limit of normal; 5) alanine aminotransferase and aspartate aminotransferase <=2.5 times upper limit of normal (ULN); 6) creatinine <=1.5 times upper limit of normal (ULN); And creatinine clearance >=60ml/min; 7) international normalized ratio (INR) of prothrombin time <=1.5 in patients without previous anticoagulant therapy; Partial thromboplastin time (APTT)<=1.5 times the upper limit of normal; 8) if HBV-DNA is detectable, antiviral therapy should be started before enrollment; 9) If HCV-RNA is detectable, antiviral therapy should be started before enrollment.
• Women of childbearing age: must agree to abstain from sexual intercourse (heterosexual intercourse) or use a reliable, effective method of contraception for at least 120 days from the time of written informed consent until the last dose of study drug is administered. A serum HCG test had to be negative within 7 days before starting study treatment; And they must be non-lactating. Women were considered to be fertile if they had menstruated, had not yet reached a postmenopausal state (>=12 months of continuous absence of menses, with no cause other than menopause identified), and had not undergone sterilization procedures (e.g., hysterectomy, bilateral tubal ligation, or bilateral oophorectomy).
• Male patients whose partner was a woman of reproductive age had to agree to abstain from sex or to use a reliable, effective method of contraception for at least 120 days from the time of written informed consent until the last dose of study drug was administered. Male patients also had to agree not to donate sperm during the same period. Male subjects whose partner was pregnant were required to use condoms.
