Clinical Trial Summary
This study is a single-center, single-arm, open-label prospective clinical trial. By
recording the disease-free progression (PFS), overall survival (OS) and tumor treatment
response of the included patients, it is planned to evaluate TACE, lenvatinib and
carrelizumab in the treatment of BCLC B/C hepatocytes Survival benefits of cancer patients;
at the same time, the immune indicators before and after treatment are tested, the dosage is
optimized, and the mechanism of combination therapy in liver cancer is explored to lay the
foundation for screening more suitable treatment populations; laboratory testing indicators
and adverse events To observe and evaluate the safety of combined therapy; adopt
immunohistochemistry, pathology, cell biology, proteomics and imagingomics methods to
comprehensively evaluate the changes after combined therapy.
Description:
At present, the treatment methods for advanced liver cancer mainly include local
interventional therapy, targeted therapy and immunotherapy.This study focused on patients
with primary HCC diagnosed clinically and radiologically, histologically, or cytologically,
in BCLC stage B/C.To study the medium and long-term efficacy of TACE and remvaritinib
combined with carrelizumab in the treatment of BCLCB/C stage liver cancer, and to evaluate
its effectiveness;To evaluate the safety and efficacy of remvatinib combined with
carrelizumab in the treatment of liver cancer, and to clarify the application value of
combined therapy, so as to lay a foundation for the evaluation of clinical efficacy in
patients with middle and advanced liver cancer.Immune checkpoint inhibitors and cell-based
cancer immunotherapies have been widely used in a variety of advanced malignancies by
modulating the tumor immune response.Studies have shown that programmed death receptor 1
(PD-1) is an immune checkpoint molecule that negatively regulates the immune function of T
cells through interaction with its ligand PD-L1.A growing body of evidence suggests that the
PD-1/PD-L1 interaction is one of the major cancer avoidance mechanisms in
humans.Overexpression of PD-L1 or PD-L2 by tumor cells interacts with PD-1 molecules
expressed in activated T cells to inhibit T cell receptor (TCR) signal transduction, and
eventually leads to inactivation of effector T cells and loss of proliferative ability,
leading to tumor immune escape.Based on this mechanism of tumors, new immunotherapies that
block the interaction between PD1/PD-L1 have been produced, changing the treatment strategies
of various malignant tumors.By inhibiting the negative regulatory effect of PD-1/PD-L1
pathway on T cells, the anti-tumor immune response of the body can be enhanced, the T cell
response activity targeting the patient's tumor can be improved, and the proliferation of
effector T lymphocytes can be promoted, finally providing an important and lasting immune
response against the patient's malignant tumor.Carrelizumab is a human high-affinity IgG4
anti-PD-1 monoclonal antibody drug independently developed by Suzhou Henrui Pharmaceutical
Co., Ltd., which can selectively block the activation of PD-1 and its downstream signaling
pathway, and restore immune function by activating effector T lymphocytes and cell-mediated
immune response.Some studies have shown that the application of carrelizumab in patients with
advanced solid tumors shows some clinical value, and predictive biomarkers such as PD-L1
expression level and tumor mutation load can screen out patients with high response to
PD-1/PD-L1 monoclonal antibodies.Even so, PD1/PD-L1 blocking therapy provides clinical
benefit in less than 20% of cancer patients,suggesting that patients using these drugs rely
solely on their insufficient preexisting endogenous anti-tumor specific T
cells.Anti-angiogenic drugs can specifically bind to vascular endothelial growth factor
(VEGF) and its receptor 2(VEGFR2), achieving the dual effect of enhancing cytotoxic
chemotherapy and achieving molecular targeted therapy.Some recent studies have shown that
angiogenesis inhibitors can regulate tumor microenvironment and relieve hypoxia of tumor
cells, which may promote tumor immune recovery .Ramvatinib mesylate is a class of
multi-target receptor tyrosine kinase inhibitors, which can block a series of regulatory
factors including VEGFR1-3, KIT and RET in tumor cells, and significantly inhibit
angiogenesis in tumor tissues.It is currently FDA approved as a first-line treatment for
patients with unresectable hepatocellular carcinoma.In a phase III clinical study, the
overall survival of remvatinib in the first-line treatment of unresectable hepatocellular
carcinoma was comparable to sorafenib (13.6 vs12.3 months) .Another basic study showed that
rumvatinib modulates cancer immunity in the tumor microenvironment by reducing
tumor-associated macrophages (TAM), and that when combined with PD-1 inhibitors, it can
enhance anti-tumor activity through the IFN signaling pathway.In addition, previous studies
have found that transarterial chemoembolization (TACE) combined with antiangiogenic agents in
the treatment of advanced hepatocellular carcinoma shows a good response to tumor treatment
compared with TACE alone, but the incidence of treatment-related adverse events is high and
the survival time of patients is not significantly improved.Therefore, in this study, TACE,
the powerful anti-angiogenic drug Ramvatinib and the new PD-1 inhibitor Carrizumab were
combined to treat liver cancer patients, so as to improve the quality of life of patients and
improve their survival benefits.This study aims to explore the clinical outcomes of TACE,
Ramvatinib combined with carririzumab in patients with stage BCLCB/C liver cancer, monitor
the complications and tumor treatment response of patients, study the appropriate population
for combined treatment, and evaluate the hepatorenal and cardiotoxicity of the drugs in
humans.Focusing on exploring the mechanism and application value of antiangiogenic therapy
combined with immunotherapy in the treatment of liver cancer, to provide new treatment
options for patients with middle and advanced liver cancer.
