Immunotherapy of Hepatocellular Carcinoma by Induction of Anti-alpha Fetoprotein Response - Full Text View

Purpose

The secretion by tumor cells of alpha fetoprotein (AFP) was observed in 50 to 60% of hepatocellular carcinoma. The AFP can be used as a marker for tumor recurrence after treatment and may be considered as a tumor antigen specific for hepatocellular carcinoma.The aim of the project is to use the alpha fetoprotein (AFP) as a tumor antigen and to propose an approach of immunotherapy for hepatocellular carcinoma based on the injection of autologous dendritic cells loaded with specific peptides of AFP.

Primary Outcome Measures:

Number of Participants with Adverse Events as a Measure of Safety and Tolerability [ Time Frame: 3 days after each injection ]
The main aim of this study is to test the absence of toxicity of the injection of autologist dendritic cells loaded with specific peptides of the AFP, for patients with hepatocellular carcinoma and already treated.
Number of Participants with Adverse Events as a Measure of Safety and Tolerability [ Time Frame: 3 weeks after the last injection ]
Number of Participants with Adverse Events as a Measure of Safety and Tolerability [ Time Frame: 3 months after the last injection ]

Secondary Outcome Measures:

Analysis of T lymphocytes [ Time Frame: before each injection ]
The secondary aim of the study is to evaluate the anti-AFP immunizing response among patients who received the treatment
Analysis of T lymphocytes [ Time Frame: 3 weeks after the last injection ]
Analysis of T lymphocytes [ Time Frame: 3 months after the last injection ]
