Hepatocellular Carcinoma
Conditions
Brief summary
This study enrolls patients who have relapsed/advanced hepatocellular carcinoma (HCC, BCLC stage C). The HCC tumor relapsed or metastasized through the body after standard treatment or the patients cannot receive standard treatment under current conditions. This research study uses special immune system cells called iNKT cells, a new experimental treatment. The purpose of this study is to find the biggest dose of iNKT cells that is safe and tolerance, to see how long they last in the body, to learn the immunoresponse in the body, to learn the side effects are and to see if the iNKT cells will help people with relapsed/advanced hepatocellular carcinoma (HCC).
Detailed description
PBMCs of enrolled patients were collected and then further separated by density gradient centrifugation. After washing three times, the cells were resuspended in serum-free medium with recombinant human IL-2 and α-GalCer. Restimulation with α-GalCer-pulsed autologous DCs was done on days 7. After 14 days of cultivation, the iNKT cells were harvested, washed thrice, and then resuspended in saline. The frequency of iNKT cells before and after cultured in vitro were determined by flow cytometry analysis.
Interventions
The patients received different doses of in vitro-expanded autologous iNKT cells through intravenous infusion. The dosage was escalated from 3x10\^7 cells/m2 to 6x10\^7 cells/m2 to 9x10\^7 cells/m2. The maximum tolerated dose (MTD) was defined as the last dose level, and the dosage would be up to 1x10\^10 cells/m2 if no MTD was observed after a 3+3 design.
IL-2 will be given at a dose of 25,000 IU/kg/day for 5-14 days.
Tegafur will be given at a dose of 40\ 60 mg bis in die (BID) 2 weeks.
