Icaritin Soft Capsule Versus Huachansu Tablet in the First-line Treatment of Unresectable Hepatocellular Carcinoma With Poor Conditions and Biomarker Enrichment (Biomarker Enrichment Study of Poor Prognosis HCC Patients, BESTPOP)

Overview

A study to evaluate the efficacy and safety of icaritin versus huachansu in the first-line treatment of unresectable hepatocellular carcinoma with poor conditions and biomarker enrichment.

Description

This is a prospective, randomized, parallel-controlled, double-blind, double-dummy, multicenter, phase III clinical trial. Patients with poor conditions and biomarker enrichment will be randomly assigned in a 2:1 ratio to receive either icaritin or huachansu as the first-line treatment until unacceptable toxic effects and loss of clinical benefit. A total of 261 participants with 206 deaths are required. The primary endpoint is overall survival (OS) in the full analysis set (FAS) population.

Eligibility

5. No prior first-line systemic treatment for HCC, including sorafenib, lenvatinib, donafenib, atezolizumab plus bevacizumab, sintilimab plus a bevacizumab biosimilar, camrelizumab plus apatinib, and durvalumab plus tremelimumab, oxaliplatin-based systemic chemotherapy (FOLFOX4) , icaritin, huachansu, and other anti-cancer drugs such as targeted agents, immune checkpoint inhibitors, and systemic chemotherapy;
6. Child-Pugh score ≤ 7;
7. Vital organ functions should meet the following requirements:

   ① Hematopoietic function: platelet ≥ 40×10^9/L, hemoglobin ≥ 80 g/L, white blood cell ≥ 2.0×10^9/L;

   ② Liver function: total bilirubin ≤ 1.5 times upper limit of normal (ULN) , alanine Aminotransferase (ALT) and aspartate Aminotransferase (AST) ≤ 5×ULN; albumin ≥ 28 g/L;

   ③ Renal function: Serum Creatinine ≤ 1.5×ULN, or creatinine clearance rate ≥ 50 mL/min;

8. If HBV-DNA ≥ 10^4 copies/mL (2000 IU/mL), antiviral and liver protection therapy must be used before enrollment, until HBV-DNA < 10^4 copies/mL (2000 IU/mL). In which case, the antiviral drugs should be administered continuously and liver function and hepatitis B virus load will be monitored during the study period;
9. Patients who meet one of two conditions: (A) are not or less appropriate candidates for first-line standard treatments recommended by the guidelines; (B) are not willing to receive first-line standard treatments recommended by the guidelines.
10. Surgical resection ended > 3 months, local ablation, hepatic artery intervention or radiotherapy ended > 4 weeks before randomization (implantation of radioactive particles ended > 3 months) and relevant adverse reactions having recovered. Patients without extrahepatic spread must have radiographic evidence of disease progression after local treatment;
11. Patients who had previously received adjuvant systemic therapy after surgical resection experienced the first radiographic disease progression more than 6 months after withdrawal of adjuvant therapy will be eligible for enrollment;
12. Within 2 weeks prior to randomization, no treatment with modern Chinese traditional medicine preparations with anti-tumor indications (refer to the 11th inclusion criterion when huaier granule was used as systemic adjuvant therapy), immunomodulators such as interferon-α and thymalfasin, tumor vaccines and cellular immunotherapy;
13. No blood transfusion or infusion of blood products, no use of hematopoietic growth factors (such as granulocyte colony-stimulating factor G-CSF), and no albumin infusion within 2 weeks prior to randomization;
14. ≥1 measurable lesion according to the Response Evaluation Criteria In Solid Tumors (RECIST 1.1), defined as a non-lymphoid lesion with the longest diameter ≥ 10 mm or a lymph node lesion with the short axis ≥ 15 mm; a lesion after previous radiotherapy or other loco-regional therapy which has been demonstrated progression confirmed per RECIST v1.1 with the longest diameter ≥ 10 mm scanned by dynamic-enhanced CT/ dynamic-enhanced MRI is to be deemed as a measurable lesion.
15. Eastern Cooperative Oncology Group (ECOG) performance score (PS) of 0 or 1;
16. Expected survival of ≥ 12 weeks;
17. Female patients of childbearing age with a negative blood pregnancy within the first 7 days prior to randomization will be eligible; Female patients of childbearing age or male patients with female sexual partners of childbearing age should take effective contraceptive measures throughout treatment and within 3 months after the last dose;
18. Voluntary agreement to sign informed consent and the willingness and ability to comply with protocol schedules and testing;
19. No treatment with any other investigational drugs or medical devices within 4 weeks prior to randomization.

Exclusion Criteria:

1. Tumor occupancy ≥ 70% of liver, or tumor thrombus occupancy ≥ 50% of the main trunk of portal vein, or mesenteric vein or inferior vena cava tumor thrombus;
2. Moderate-to-severe ascites, i.e., the score of the indicator is > 2; Moderate-to-severe, or symptomatic pleural effusion and pericardial effusion requiring drainage;
3. Receipt of major surgery (craniotomy, thoracotomy, laparotomy, hip replacement, etc.) within 28 days prior to randomization or planned to receive major surgery during the study;
4. Other types of primary liver cancer, such as intrahepatic cholangiocarcinoma, mixed HCC and cholangiocarcinoma, fibrolamellar HCC, etc. Other malignancies within 5 years prior to signing the informed consent form or at present, excluding radically treated basal cell carcinoma of skin, squamous cell carcinoma of skin and/or radically resected carcinoma in situ;
5. Pregnant or lactating women;
6. Grade 2 or above myocardial ischemia or myocardial infarction (NCI-CTCAE v5.0), poorly-controlled arrhythmia, and/or New York Heart Association (NYHA) class III or IV cardiac insufficiency;
