Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Peptide vaccination

Arm Description

VEGFR1-derived HLA-A*02:01-restricted peptide (VEGFR1-A2-770; TLFWLLLTL)was vaccinated twice weekly for 8 weeks (total 16 doses) combined with conventional dose (1,000 mg/m^2 body surface area) of gemcitabine 6 doses for advanced stage pancreatic cancer to confirm the safety and efficacy of this type of peptide.

Outcomes

Primary Outcome Measures

Number of Participants Without Grade 4 Hematological or Grade 3 to 4 Non-hematological Adverse Events
Number of participants without grade 4 hematological or grade 3 other adverse events were caslculated based on the National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0 (NCI CTCAE v.3)

Secondary Outcome Measures

Number of Participants With Tumor Regression
Sum of diameters of primary pancreatic tumor or metastatic tumors (target lesions) before and after vaccination were measured by computed tomography. Sum of tumors' size diameters decrease more than 30% after vaccination was diagnosed as response according to the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.0 guidelines.

5. Study Description

Brief Summary
Pancreatic cancer is the fourth leading cause of cancer death in the United States, and no combination therapy is far superior to gemcitabine alone. Vascular endothelial growth factor receptor type 1 (VEGFR1) is expressed on the tumor vessels and a candidate of tumor vessel-specific peptide vaccination strategy to induce T cell immune response. We conducted the study to confirm the safety and efficacy of combined modality intervention using conventional dose of gemcitabine with peptide vaccination targeting tumor-vessel specific VEGFR1 in case of advanced/inoperable or therapy-resistant pancreatic cancer patients. Gemcitabine 1,000 mg/m^2 (body surface area) will be administered on day 1, day 8, day 15, day 29, day 36, and day 43, respectively. VEGFR1-derived HLA-A*02:01-restricted peptide (VEGFR1-A02-770; TLFWLLLTL) emulsified with Montanide ISA51 will be subcutaneously injected twice weekly for 8 weeks (total 16 doses).
Detailed Description
HLA-A*02:01-restricted VEGFR1-specific cytotoxic T lymphocyte (CTL) responses were obtained from HLA-A2/Kd transgenic murine model. HLA-A*02:01-restricted VEGFR1-specific CTL clones were also obtained from peripheral blood mononuclear cells of healthy volunteer donors. These CTL clones showed potent anti-tumor CTL responses in HLA class Ⅰ-restricted manner in vitro. Vaccination of HLA-A*02:01-restricted VEGFR1-specific peptide to A2/Kd transgenic mice markedly suppress the tumor-induced angiogenesis and tumor growth in vivo.
