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)

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.


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.


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.

Inclusion Criteria:

- Patients must have histologically or cytologically confirmed pancreatic adenocarcinoma

- Patients may have locally advanced disease, not amenable to curative resection; the
site of pancreatic cancer must be amenable to endoscopic ultrasound (EUS) injection;
patients with newly diagnosed metastatic disease of small volume may be included in
the study at the investigator's discretion; such patients would be limited to those

- Liver involvement < 10% of volume and no metastasis > 2 cm, and/or

- Pulmonary involvement with no respiratory compromise and no metastasis > 2cm

- Peritoneal disease and no metastasis > 2 cm and without ascites (as might be
found on exploratory laparoscopy)

- Eastern Cooperative Oncology Group (ECOG) performance status =< 1 (Karnofsky >= 80%)

- Patients (in the opinion of the principal investigator) should be able to complete a
full 3-month course of vaccination preferably with an anticipated survival of 6 months
or longer

- Leukocytes >= 3,000/mcL

- Hemoglobin >= 8 gms/dL

- Absolute neutrophil count >= 1,500/mcL

- Platelets >= 100,000/mcL

- Total bilirubin =< 1.5 X institutional upper limit of normal

[SGOT])/alanine aminotransferase (ALT)(serum glutamate pyruvate transaminase [SGPT])

- Prothrombin time (PT)/partial thromboplastin time (PTT) within normal institutional

- Amylase/lipase =< 1.5 X institutional upper limit of normal

- Creatinine =< 1.5 X institutional upper limit of normal

- Urine Protein =< grade 1 or 24-hour urine protein =< 1000 mg for patients with
proteinuria above 1+

- Urinalysis: No evidence of casts

- The effects of PANVAC-V (vaccinia) and/or PANVAC-F (fowlpox) on the developing human
fetus are unknown; 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; topical steroids,
steroid eye drops or inhaled steroids are contraindicated for at least 2 weeks before
vaccinia vaccination and at least 4 weeks post vaccinia vaccination

- Uncontrolled intercurrent illness including, but not limited to active infection,
symptomatic congestive heart failure or documented cardiomyopathy, unstable angina
pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would
limit compliance with study requirements; patients with symptomatic cardiac disease or

months of entry, and/or unstable or uncontrolled arrhythmia or angina
