Start date February 2010
End date November 2013
Trial size 18 participants

Summary

This phase I trial studies the side effects and best dose of vaccine therapy when given together with sargramostim in treating patients with locally advanced or metastatic pancreatic cancer that cannot be removed by surgery. Vaccines made from a gene-modified virus may help the body build an effective immune response to kill tumor cells. Colony-stimulating factors, such as sargramostim, may increase the number of immune cells found in bone marrow or peripheral blood. Giving vaccine therapy directly into the tumor together with sargramostim may cause a stronger immune response and kill more tumor cells.

(Experimental)
Patients receive falimarev vaccine intratumorally using endoscopic ultrasound guidance on day 1. Patients also receive inalimarev vaccine SC on day 1 and sargramostim SC on days 1-4. Patients then receive falimarev vaccine SC on days 15 and 29 and sargramostim SC on days 15-18 and 29-32 in the absence of unacceptable toxicity. Beginning on day 43, patients with stable or improving pancreatic cancer receive falimarev vaccine SC and sargramostim SC (given on the day of and for 3 days after each falimarev vaccination) monthly in the absence of disease progression or unacceptable toxicity. Beginning on day 71, patients with no irreversible or dose limiting toxicity, receive falimarev vaccine SC and sargramostim SC (given on the day of and for 3 days after each falimarev vaccination) monthly in the absence of disease progression or unacceptable toxicity.

for this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for four months following the last vaccine dose; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately - Patients may not have any other active illness (e.g., uncontrolled infection, uncontrolled cardiac disease) that would preclude safe therapy - Patients must sign a written informed consent document Exclusion Criteria: - Patients may not have had radiotherapy to the pancreas - Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier - Patients may not be receiving nor have received any other investigational agents within 28 days prior to registration - Patients with known brain metastases should be excluded from this clinical trial - History of allergic reactions or severe adverse reactions attributed to compounds of similar chemical or biologic composition to PANVAC-V (vaccinia) and/or PANVAC-F (fowlpox) which include but are not limited to the viral vectors vaccinia (small pox vaccination) and fowlpox, allergy to GM-CSF or to eggs which are used for the production of the vaccine - Systemic corticosteroid therapy within 28 days of registration;

Official title Immunotherapy for Unresectable Pancreas Cancer: A Phase 1 Study of Intratumoral Recombinant Fowlpox PANVAC (PANVAC-F) Plus Subcutaneous Recombinant Vaccinia PANVAC (PANVAC-V), PANVAC-F and Recombinant Granulocyte-Macrophage Colony Stimulating Factor (rH-GM-CSF)
Principal investigator Elizabeth Poplin
Description PRIMARY OBJECTIVES: I. To determine the tolerability of delivering two standard doses of the PANVAC-F (fowlpox) (falimarev) vaccine administered intratumorally in conjunction with subcutaneous injections of PANVAC-V (vaccinia) (inalimarev) followed by PANVAC-F (fowlpox) in conjunction with rH-GM-CSF (sargramostim) versus (vs.) subcutaneously injected PANVAC-V or PANVAC-F in conjunction with rH-GM-CSF in patients with incurable pancreatic cancer based on local unresectability or with small volume metastases. SECONDARY OBJECTIVES: I. To assess the toxicity of the vaccine injections. II. To assess evidence of tumor response by imaging and tumor marker response. III. To assess gene transfer to pancreatic tissue. IV. To assess immunologic response to PANVACTM. OUTLINE: This is a dose-escalation study of falimarev. Patients receive falimarev vaccine intratumorally using endoscopic ultrasound guidance on day 1. Patients also receive inalimarev vaccine subcutaneously (SC) on day 1 and sargramostim SC on days 1-4. Patients then receive falimarev vaccine SC on days 15 and 29 and sargramostim SC on days 15-18 and 29-32 in the absence of unacceptable toxicity. Beginning on day 43, patients with stable or improving pancreatic cancer receive falimarev vaccine SC and sargramostim SC (given on the day of and for 3 days after each falimarev vaccination) monthly in the absence of disease progression or unacceptable toxicity. Beginning on day 71, patients with no irreversible or dose limiting toxicity, receive falimarev vaccine SC and sargramostim SC (given on the day of and for 3 days after each falimarev vaccination) monthly in the absence of disease progression or unacceptable toxicity. Patients undergo biopsy periodically for correlative studies. After completion of study treatment, patients are followed every 3 months.
