Locally Advanced Hepatocellular Carcinoma Clinical Trial
Official title:
A Phase 2a Study Using Natural Killer (NK) Cell Therapy Combined With Hepatic Artery Infusion Chemotherapy (HAIC) in Patients With Locally Advanced Hepatocellular Carcinoma
This Phase 2a trial will evaluate the safety and efficacy of NK cell therapy combined with the hepatic artery infusion chemotherapy (HAIC) in patients with intermediate and/or locally advanced hepatocellular carcinoma (HCC). We hypothesized that 5-fluorouracil (FU) with immunomodulatory functions would relieve the immunosuppressive microenvironment from the myeloid-derived suppressor cells (MDSCs), thereby enhancing the anti-tumor activity of NK cells. Thus, the subsequent infusion of autologous NK cells (VAX-NK/HCC) following HAIC treatment may further improve the anti-tumor activity in patients with advanced HCC.
Primary Objective I. To assess the objective response rate (ORR) of administering VAX-NK/HCC, autologous NK cells combined with HAIC in patients with locally advanced HCC. Secondary Objectives I. To assess the efficacy of administering VAX-NK/HCC combined with HAIC. II. To assess the safety of administering VAX-NK/HCC combined with HAIC. III. To assess the immune responses of administering VAX-NK/HCC combined with HAIC. OUTLINE: This is a Phase 2a study. Patients receive HAIC treatment every 4 week for up to 4 cycles followed by ex-vivo expanded autologous NK cell infusions. The NK cell treatment repeats every 4 weeks for up to 2 cycles in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients will be followed until the disease progression. ;
