Peptide vaccine. (A) In the peptide vaccine, rindopepimut, EGFRvIII peptide is fused with highly immunogenic KLH (PEPvIII-KLH) for vaccine preparation. (B) The vaccine is administered intradermally and the antigen is recognized by APCs. (C) APCs present to T-cells and CTLs. (D) T-cells activate B-cells which then produce antibodies to EGFRvIII in the tumor. CTLs cross the blood brain barrier and target GBM cells with EGFRvIII on the surface. This activation of T-cells and CTLs results in anti-tumor response.
