El-porCEA
The purpose of this study is to evaluate the safety and immunogenicity of a CEA DNA immunisation approach in patients with colorectal cancer. The DNA plasmid, tetwtCEA, encodes wild type human CEA fused to a tetanus toxoid T helper epitope. The vaccine will be delivered using an intradermal electroporation device, Derma Vax (Cyto Pulse Sciences). The following will be assessed: The efficiency of priming immunological responses to CEA by intradermal administration of CEA DNA in combination with electroporation.
The efficiency of boosting immunological responses to CEA by intradermal administration of CEA DNA in combination with electroporation in subjects already vaccinated with CEA DNA.
GM-CSF will be administered to half of the subjects primed with CEA DNA in combination with electroporation and any possible adjuvant effects of GM-CSF will be evaluated.
