|ClinicalTrials.gov Identifier: NCT00683358|
Recruitment Status : Unknown
Verified January 2009 by Tokyo University.
Recruitment status was: Active, not recruiting
First Posted : May 23, 2008
Last Update Posted : May 7, 2009
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).
|Condition or disease||Intervention/treatment||Phase|
|Pancreatic Cancer Pancreas Neoplasms||Biological: VEGFR1-A24-1084 (SYGVLLWEI)||Phase 1 Phase 2|
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.
|Study Type :||Interventional (Clinical Trial)|

|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|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|
