Human Leukocyte Antigen-A*2402-Restricted Tumor Vessel Specific Peptide Vaccination for Advanced Pancreatic Cancer

Summary

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).
