A Feasibility and Safety Study of Vaccination With Poly-ICLC and Peptide-pulsed Dendritic Cells in Patients With Metastatic, Locally Advanced, Unresectable, or Recurrent Pancreatic Adenocarcinoma
This trial is active, not recruiting.
|Condition||metastatic pancreatic cancer|
|Treatment||vacc. w/ poly-iclc & peptide-pulsed dendritic cells|
|Sponsor||Medical University of South Carolina|
|Start date||August 2011|
|End date||November 2013|
|Trial size||12 participants|
|Trial identifier||NCT01410968, 101498|
The purpose of this study is to provide a safety and feasibility basis for future studies addressing the hypothesis that subcutaneous vaccination with dendritic cells loaded with multiple antigenic epitopes expressed by pancreatic tumor in combination with systemic administration of Poly-ICLC (Hiltonol) will induce anti-tumor immunity.
|Endpoint classification||safety study|
|Intervention model||single group assignment|

Male or female participants at least 18 years old.
Eligibility Criteria: - Patients must have histologically or cytologically confirmed diagnosis of pancreatic adenocarcinoma that is metastatic, locally advanced, unresectable, or recurrent. Patients with endocrine or neuroendocrine tumors, lymphoma of the pancreas, or ampullary cancer are not eligible. If the histologic diagnosis is based on a metastatic site, the histology must be compatible with pancreatic cancer. - Patient must not have clinically significant ascites. - Patients must be HLA-A2 positivity by serological testing. - Prior surgery is allowed provided at least 14 days has elapsed between surgery and registration. Prior radiation/chemo is allowed provided that at least 28 days have elapsed since the last treatment. - One or more tumors measurable on CT scan per RECIST 1.1. (Eisenhauer) - Eastern Cooperative Oncology Group (ECOG) performance status < 2. - Age > 18 years. - Patient must have an expected life expectancy greater than 3 months. - Signed, written IRB-approved informed consent. - A negative pregnancy test (if female). - Acceptable organ function: - Bilirubin < 3 times upper limit of normal (CTCAE Grade 2 baseline) - AST (SGOT), ALT (SGPT) < 3 x ULN (CTCAE Grade 1 baseline) - Serum creatinine < 1.5 XULN (CTCAE Grade 1 baseline) - Acceptable hematologic status: - Absolute neutrophil count > 1000 cells/mm3, - Platelet count > 75,000 (plt/mm3), (CTCAE Grade 1 baseline) - Hemoglobin > 9 g/dL. - Urinalysis: No clinically significant abnormalities. - PT and PTT < 1.5 X ULN after correction of nutritional deficiencies that may contribute to prolonged PT/PTT. - No evidence of clinically significant, uncontrolled cardiovascular, endocrine, or infectious disease. Exclusion Criteria - Patients must not have any serious uncontrolled acute or chronic medical condition that would interfere with this treatment. An example would be an active acute or chronic infection requiring antibiotics - Patients must not have significant ongoing cardiac problems, myocardial infarction within the last six months, uncontrolled hypertension, unstable angina, uncontrolled arrhythmia or congestive heart failure. - Patients with known brain metastases are not eligible. However, brain-imaging studies are not required for eligibility if the patient has no neurologic signs or symptoms. If brain-imaging studies are performed, they must be negative for disease. - Patients must have no plans to receive concurrent chemotherapy, hormonal therapy, radiotherapy, immunotherapy or any other type of therapy for treatment of cancer while on this protocol treatment. - Due to the undetermined effect of this treatment regimen in patients with HIV-1 infection and the potential for serious interaction with anti-HIV medications, patients known to be infected with HIV are not eligible for this study. - Due to the possibility of harm to a fetus or nursing infant from this treatment regimen, patients must not be pregnant or nursing. Women and men of reproductive potential must have agreed to use an effective contraceptive method. - No other prior malignancy is allowed except for the following: adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, adequately treated Stage I or II cancer from which the patient is currently in complete remission, or any other cancer from which the patient has been disease free for five years.
|Official title||A Feasibility and Safety Study of Vaccination With Poly-ICLC and Peptide-pulsed Dendritic Cells in Patients With Metastatic, Locally Advanced, Unresectable, or Recurrent Pancreatic Adenocarcinoma|
|Description||Primary Objectives 1. Assess the safety of this treatment by evaluating the qualitative and quantitative toxicities in this group of patients. 2. Determine the feasibility of generating dendritic cells and administering these cells as a vaccine to patients. Secondary Objectives 1. Assess anti-tumor activity after vaccination, measured by change in tumor burden and overall survival. 2. Assess immunological responses after vaccination (antigen-specific T cell cytokine production, antigen-specific T cell frequencies by tetramer analysis, and DTH reactions)|
