the phase iii study of icaritin versus huachansu pian in hepatocellular carcinoma subjects

Conditions: Advanced HBV-Related Hepatocellular Carcinoma (HCC)

Summary: the enriched hbv-related advanced hcc patient population (composite biomarker score ≥ 2) and overall survival (os) were compared between the two groups.

the basis of enrichment design adjustment ： the latest published literature shows that the heterogeneity and immune tolerance of patients with hepatitis b virus (hbv) - related hcc are significantly correlated with a number of cytokines, including helper t cell subgroup 1 / 2 (th1 / th2) related factors. moreover, the accumulated data show that the immunomodulatory effect of flavonoids including icaritin is related to th1 / th2 factors. at the same time, the recent reach2 study published in lancet oncology has successfully used serum alpha fetoprotein (afp≥400) to enrich patients with advanced hcc. based on the updated published data and our phase ii clinical trial data, considering that the ongoing clinical trials are still in a blind state and no statistical analysis has been conducted, with consulting of clinical experts, regulatory agency advice, the protocol was amended and approved into adaptive enrichment design. before unblended and sap, the amendment protocol was prospectively pre-defined including sample size, patient population (cbs score positive), and event number for interim and final analysis. combined with the latest fda clinical trial enrichment design guidelines (2019), several experts recommended to use the composite biomarkers, including ifn-γ , tnf - α and afp, which may demonstrate the clinical advantages of the immunomodulation therapy with icaritin for hbv-related advanced hcc patients in china with poor prognosis, but currently lack of treatment options. definition of enriched hbv-related advanced hcc patient: patient with serum composite biomarker score (cbs)≥2 enrichment design amendment: based on our previous phase ii data of icaritin collected from hbv-related advanced hcc patients and the related literature, we assume that the mos of the enriched population (cbs≥2) is 420 days (14 months) in the experimental group and 240 days (8 months) in the huachashu control group; the hr of the experimental group relative to the control group is 0.57. a total of 106 target death events and 130 evaluable subjects were required for the enrichment. once the amendment protocol be effective, the enriched and non-enriched patients will be continuously randomized into the experimental and the control arms accordingly (1:1). when the number of enrolled cases reaches 280, or 60% of events (64) of 106 deaths has been observed in the enriched population, interim analysis will be performed.

Eligibility criteria:
inclusion criteria: * only patients who meet all the following criteria are included in the study: 1) age≥18years, no gender restriction; 2) advanced or metastatic hcc patients in strict compliance with the "primary liver cancer diagnosis and treatment standard" (2017 edition) issued by the national health and family planning commission, clinical diagnostic criteria and/or diagnosed by pathology /cytology, patients who fail to undergo liver surgery and/or other local treatment (ablation or hepatic artery intervention), or patients who have recurrence and progression after surgery and/or other local treatment; 3) not previously accepted first-line system therapy (systemic chemotherapy, molecular targeting, immunotherapy and research medication, etc.) for advanced or metastatic hcc, including but not limited to systematic chemotherapy with oxaliplatin, sorafenib, pd-1/pd-l1 antibody, icaritin and cinobufotalin, etc.; 4) liver surgery was performed more than 3 months ago, ablation or interventional treatment of hepatic artery was performed more than 4 weeks ago, and the adverse reactions returned to normal; after surgery or other local treatment, if patients have gone beyond the norm for systemic adjuvant chemotherapy, it will need more than 6 months after the chemotherapy, and disease progression and / or metastasis have occurred; 5) for patients who are not suitable for first-line treatment of advanced hcc which is recommended in "primary liver cancer diagnosis and treatment standard." issued by the national health and family planning commission, it's mainly due to partial blood test indicators (see the relaxed scope in 11th inclusion criteria ) or other indicators (including mild ascites and so on) which are not suitable for the existing first-line standard treatment; or in particular cases, the patients insist on refusing to accept the existing first-line standard treatment(for example, patients feel that their physical condition is weak and / or economic constraints, which must be strictly mastered and controlled); 6) 2 weeks before the first medication of the trial, there is no use of modern chinese medicine preparation with liver cancer indication, including delisheng injection, kanglaite injection or soft capsule, aidi injection or considi injection, elemene injection/oral liquid, 1) 7) no use of blood transfusion or blood products, no use of hematopoietic stimulating factor, no transfusion of albumin or blood products 14 days before screening; 8) according to the evaluation criteria of solid tumor reaction (recist 1.1), it has at least one measurable target lesion, which defined as non-lymph node lesions with the longest diameter larger than 10mm, lymph node lesions with the short diameter larger than 15mm; the lesions previously received local treatment such as ablation or hepatic artery interventional therapy should be detected by computed tomography (ct) / magnetic resonance imaging (mri) and according to recist1.1, it's sure that disease progression has occurred and the longest diameter is more than 1.0cm,it can be used as a measurable target lesions; 9) the child-pugh score of liver function is grade a or better grade b (score≤7); 10) the ecog score of physical condition is 0-1; 11) expected survival time≥12 weeks; 12) the function of the main organs is basically normal and meets the following requirements: ①marrow: there is no blood transfusion and use of hematopoietic cell stimulating agent, including granulocyte colony stimulating factor (g-csf)within 14 days before screening, platelet≥60×10e9/l, hemoglobin≥ 85g/l, white blood cell≥3.0×10e9/l; after a thorough measurement of the patient's condition, the above three items can be appropriately relaxed by the principal researchers at the research centre as: platelet 50 \~60×10e9/l, hemoglobin 80\~85g/l, white blood cell 2.5 \~3.0×10e9/l (contains critical values);
