The present application relates to an antigen peptide derived from the sequence of epidermal growth factor receptor having T790M point mutation and a pharmaceutical composition for the treatment of cancer comprising the peptide.
1 - 8 . (canceled)
9 . A method of treating cancer in a subject in need thereof, comprising
administering peptide-specific cytotoxic T lymphocytes (CTLs) to the subject, wherein the CTLs are prepared by contacting a peptide consisting of the amino acid sequence of SEQ ID NO: 5,7 or 15 with peripheral blood mononuclear cells (PBMCs) to induce the CTLs; or
administering antigen presenting cells that express a peptide consisting of the amino acid sequence of SEQ ID NO: 5,7 or 15 to the subject.
10 . The method according to claim 9 , comprising administering the CTLs to a subject in need thereof.
11 . The method according to claim 9 , comprising administering the antigen presenting cells to a patient in need thereof.
12 . The method according to claim 11 , wherein the antigen presenting cells are prepared by
culturing cells in the presence of the peptide such that the peptide is bound to and presented on an human leukocyte antigen (HLA) molecule of the cells, or
introducing a vector expressing the peptide into the cells such that the peptide is expressed in the cells.
13 . The method according to claim 12 , wherein the cells are dendritic cells.
14 . The method according to claim 13 , wherein the dendritic cells are prepared from peripheral blood mononuclear cells (PBMCs).
