Trial Identification

Brief Title: "Cocktail" Therapy for Hepatitis B Related Hepatocellular Carcinoma

Official Title: Precision Study on "Cocktail" Therapy to Improve the Efficacy of Hepatitis B-related Hepatocellular Carcinoma

Study ID: NCT04317248

Conditions

Hepatocellular Carcinoma

Interventions

Cyclophosphamide

Multiple Signals loaded Dendritic Cells Vaccine

Study Description

Brief Summary: The effect of anti-tumor treatment is not satisfying in HBV-related hepatocellular carcinoma (HBV-HCC) for reasons that HBV-HCC carries highly heterogeneous antigens to facilitate cancer cells escaping from immune surveillance and constructs an immunosuppressive microenvironment. Correspondingly, multiple signals loaded dendritic cells vaccine can efficiently present T cells with antigens of HCC sensitize their antitumor properties meanwhile low dose cyclophosphamide (CY) can effectively improve the microenvironment of immunity. Therefore, we put forward a new scientific therapy called "multiple signals loaded dendritic cells vaccine combined low dose of cyclophosphamide" combining with radical surgery or TACE or targeted agents for patients with hepatocellular carcinoma to prolong their survival time.

Detailed Description: Detailed Description Patients who have good compliance complying with the inclusion criteria will be enrolled into our research. The 600 patients will be randomly assigned to experimental group and control group with the ratio of 1:1, control group will receive radical surgery or TACE or targeted agent treatment solely; another group (experimental group) after enrollment will radical surgery or TACE or targeted agent treatment in the first course. Then 20ml blood is taken for multiple signals loaded dendritic cells (MSDCV) culture (cell culture takes 7 days). Low dose (250mg/m\^2) CY treatment will be performed on patients two days before the MSDCV treatment. The MSDCV combined CY therapy will perform per 4 weeks, total 6 times. All patients are evaluated the safety and efficacy of treatment by monitoring their blood parameters, tumor indicators and imaging examinations at each visit.
