Human Leukocyte Antigen-A*2402-Restricted Tumor Vessel Specific Peptide Vaccination for Advanced Pancreatic Cancer
Recruitment status was: Active, not recruiting
Feasibility and efficacy of combined modality intervention using chemotherapeutic agent gemcitabine with anti-angiogenic peptide vaccination targeting VRGFR1 should be determined in case of advanced/inoperable or therapy-resistant pancreatic cancer patients.
Gemcitabine 1,000mg/m2 BSA will be administered on day1, day8, day15, day29, day36, day43, respectively.
HLA-A*2402-restricted VEGFR1-derived peptide (VEGFR1-A24-1084; SYGVLLWEI) emulsified with Montanide ISA51 will be subcutaneously injected twice weekly for 8weeks (total 16 doses).

HLA-A*2402-restricted VEGFR1-derived peptide (VEGFR1-A24-1084) 1mg emulsified with Montanide ISA51 will be subcutaneously injected 2 times weekly for total 16doses concurrently with conventional dose of gemcitabine 1,000mg/m2 BSA on 1st, 2nd, 3rd, 5th, 6th, 7th weeks for advanced/inoperable pancreatic cancer patients.
HLA-A*2402-restricted cytotoxic T lymphocyte (CTL) clones were obtained from healthy volunteer donor peripheral blood.
These CTL clones showed potent cytotoxicities selectively against VEGFR1-expressing target cells in HLA-class I-restricted manner.
