Gemcitabine With Antiangiogenic Peptide Vaccine Therapy in Patients With Pancreatic Cancer
Phase I Study of Gemcitabine With Antiangiogenic Vaccine Therapy Using Epitope Peptide Restricted to HLA-A*2402 Derived From VEGFR2 in Patients With Unresectable, Locally Advanced, Recurrent or Metastatic Pancreatic Cancer
The purpose of this study is to evaluate the safety, tolerability and immune response of different doses of VEGFR2-169 emulsified with Montanide ISA 51 in combination with gemcitabine and to determine the recommended phase II dose.
Vascular endothelial growth factor receptor 2(VEGFR2) is essential target for tumor angiogenesis, and VEGFR2-169 induces specific Cytotoxic T lymphocytes (CTL) against VEGFR2 expressed targets. VEGFR2-169 shows strong anti-tumor effects restricted to HLA-A*2402 in vitro, and this peptide induces CTL from cancer patients. 60% in Japanese population have HLA-A*2402. VEGFR2-169 is suitable for clinical trial, and gemcitabine has been approved against pancreatic cancer. Gemcitabine is reported to improve immune-response, therefore synergistic effect between vaccine therapy and chemotherapy will be expected. In this clinical trial, we evaluate the safety, tolerability and immune response of different doses of VEGFR2-169 emulsified with Montanide ISA 51 in combination with gemcitabine and to determine the recommended phase II dose of peptide.
Interventional
Phase 1
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Pancreatic Cancer
Biological: VEGFR2-169 and gemcitabine
Escalating doses of VEGFR2-169 will be administered by subcutaneous injection on days 1,8,15 and 22 of each 28-day treatment cycles(doses of 0.5,1.0,2.0mg/body are planned). Gemcitabine will be administered intravenously at a fixed dose of 1000mg/m2 on days 1,8 and 15. Repeated cycles of VEGFR2-169 and gemcitabine will be administered until patients develop progressive disease or unacceptable toxicity,or for maximum 2 cycles, whichever occurs first.
Experimental: Phase I study
Intervention: Biological: VEGFR2-169 and gemcitabine
