Brief Summary

Official Title: “Phase Ⅰ/Ⅱ Trial of Human Leukocyte Antigen (HLA)-A*2402-Restricted Vascular Endothelial Growth Factor Receptor 1 (VEGFR1)-Derived Peptide Vaccination Combined With Gemcitabine for Advanced Pancreatic Cancer”

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).

  • Study Type: Interventional
  • Study Design: Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
  • Study Primary Completion Date: April 2009

Detailed Clinical Trial Description

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.

Intervention(s) in this Clinical Trial

  • Biological: VEGFR1-A24-1084 (SYGVLLWEI)
    • 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.
