Adjuvant Allogeneic Tumor Cell Vaccine With Metronomic Oral Cyclophosphamide and Celecoxib in Patients Undergoing Resection of Sarcomas, Melanomas, Germ Cell Tumors, or Epithelial Malignancies Metastatic to Lungs, Pleura, or Mediastinum
Background:
- Certain types of cancers, including sarcoma and melanoma, have specific antigens (protein
molecules) on their surfaces. Research has shown that producing an immune reaction to these
antigens may be able to keep tumors from growing by encouraging the immune system to destroy
the tumor cells. By creating a vaccine that contains antigens similar to those found on the
cancer cells, researchers hope to cause an immune reaction that targets the cancer cells.
However, more research is needed to determine the safety and effectiveness of this type of
vaccine treatment.
Objectives:
- To determine whether a tumor cell vaccine, given to individuals who have had surgery to
remove malignant tumors from the chest, can cause an immune reaction that will prevent the
tumors from coming back.
Eligibility:
- Individuals at least 18 years of age who have been diagnosed with cancer that has spread to
the lungs, pleura, or mediastinum, and have recently had surgery to remove tumors in the
chest.
Design:
- Participants will be screened with a physical examination and medical history, as well
as blood tests and imaging studies.
- Participants will have the option to have leukapheresis to collect white blood cells for
studies on how the body is responding to the vaccine. Participants who agree to have
this procedure will have it before the start of treatment and after the sixth and eighth
vaccines.
- Seven days before the first vaccine, participants will receive the chemotherapy drugs
celecoxib and cyclophosphamide to take twice a day at home.
- Participants will receive the experimental vaccine as an injection in the thigh or arm,
and may receive it in two shots depending on how many cells are in each vaccine.
Participants will receive a diary to monitor medication doses and side effects, as well
as additional cyclophosphamide and celecoxib to take at home as directed by the study.
- Participants will have one vaccine every month for 6 months, and will have regular blood
tests and imaging studies. After the sixth vaccine, participants who have successfully
responded to the treatment will have two additional vaccines given 3 months apart.
- After the eighth vaccine, participants will have followup visits every 3 months for 1
year and then every 6 months for up to 4 years.

Background:
During recent years, the cancer-testis (CT) antigens (CTA) have emerged as attractive targets
for cancer immunotherapy. Whereas malignancies of diverse histologies express a variety of
CTAs, immune responses to these antigens appear uncommon in cancer patients, possibly due to
low-level, heterogeneous antigen expression, as well as immunosuppressive regulatory T cells.
Conceivably, vaccination of cancer patients with allogeneic tumor cells expressing high
levels of multiple CTAs in combination with depletion of T regulatory cells will induce broad
immunity to these antigens. In order to examine this issue, patients with sarcomas,
melanomas, germ cell tumors, or epithelial malignancies metastatic to lungs, pleura or
mediastinum will be vaccinated with irradiated K562 erythroleukemia cells expressing GM-CSF
(K562-GM) following thoracic metastasectomy. Vaccines will be administered in conjunction
with metronomic oral cyclophosphamide (50 mg PO BID x 7d q 14d), and celecoxib (400 mg PO
BID). Serologic responses to a variety of recombinant CTAs will be assessed before and after
vaccination.
Primary Objectives:
-To assess the safety of K562-GM allogeneic tumor cell vaccines in combination with oral
metronomic cyclophosphamide and celecoxib in patients undergoing thoracic metastasectomy.
Eligibility:
- Patients with histologically or cytologically proven sarcoma, melanoma, or epithelial
malignancies metastatic to lungs, pleura or mediastinum who can be rendered no clinical
evidence of active disease (NED).
- Patients must be 18 years or older with an ECOG performance status of 0 2, without
evidence of unstable or decompensated myocardial disease. Patients must have adequate
pulmonary reserve evidenced by FEV1 and DLCO equal to or greater than 30% predicted;
pCO2 less than 50 mm Hg and pO2 greater than 60 mm Hg on room air ABG; and be on no
immunosuppressive medications except inhaled corticosteroids at the time vaccination
commences.
- Patients must have a platelet count greater than 100,000, an ANC equal to or greater
than 1500 without transfusion or cytokine support, a normal PT, and adequate hepatic
function as evidenced by a total bilirubin of <1.5 times upper limits of normal. Serum
creatinine less than or equal to 1.6 mg/ml or the creatinine clearance must be greater
than 70 ml/min/1.73m(2) at the time vaccination commences.
Design:
- Following recovery from thoracic metastasectomy, patients with NED or MRD will be
vaccinated via deep subcutaneous injection with 1x10(8) irradiated K562 GM-tumor cells
periodically over 6 months.
- Vaccines will be administered in conjunction with metronomic oral cyclophosphamide and
celecoxib.
- Systemic toxicities, and immunologic response to therapy will be recorded. Pre and post
vaccination serologic responses to a standard panel of CT antigens as well as cell
mediated responses to epigenetically-modified autologous EBV-transformed B and
autologous tumor cells (if available) will be assessed before and after vaccination.
- Numbers/percentages and function of T regulatory cells in peripheral blood will be
assessed before, during, and after vaccinations.
- Patients will be followed in the clinic with routine staging scans until disease
recurrence.
- As the exact set of comparisons and analyses to be performed will be determined
following completion of the trial, and will be based on limited numbers of patients, the
analyses will be considered exploratory and hypothesis generating rather than
definitive.
- Approximately 25 patients will be accrued to this trial.

- INCLUSION CRITERIA:
1. Patients with sarcomas, melanomas, germ cell tumors, or epithelial malignancies
metastatic to the lungs, mediastinum, or pleura that have no clinical evidence of
active disease (NED).
2. Patients with active disease outside the thorax may be eligible for study once
the extrathoracic disease is definitively treated by local modalities such as
radiation, surgery, or radiofrequency ablation.
3. Patients must have received or refused first line standard systemic therapy for
their metastases (if applicable).
4. Patients must be enrolled within 52 weeks following completion of metastasectomy
and have shown no evidence of disease during that time.
5. Patients with intracranial metastases, which have been treated by surgery or
radiation therapy may be eligible for study provided there is no evidence of
active disease and no requirement for anticonvulsant therapy or steroids
following treatment.
6. Patients must have an ECOG performance status of 0 2.
7. Patients must be 18 years of age or older due to the unknown effects of
immunologic responses to germ cell-restricted gene products during childhood and
adolescent development.
8. Patients must have evidence of adequate bone marrow reserve, hepatic and renal
function as evidenced by the following laboratory parameters:
- Absolute neutrophil count greater than 1500/mm(3)

must be greater than 70 ml/min/1.73m(2).
9. Seronegative for HIV antibody. Note: The experimental treatment being evaluated
in this protocol depends on an intact immune system. Patients who are HIV
seropositive can have decreased immune competence and thus may be less responsive
to the experimental treatment.

and risks.
12. Patients must be willing to practice birth control during and for four months
following treatment.
13. Patients must be willing to sign an informed consent.
EXCLUSION CRITERIA:
1. Patients who are initially rendered NED by surgical therapy but exhibit disease
progression prior to initiation of vaccination will be excluded from the study.

by uncontrolled arrhythmias, unstable angina, decompensated CHF (>NYHA Class II), or
myocardial infarction within 6 months of study will be excluded.
6. Patients with other cardiac diseases may be excluded at the discretion of the PI
following consultation with Cardiology consultants.
7. Patients with any of the following pulmonary function abnormalities will be excluded:
FEV, < 30% predicted; DLCO < 30% predicted (postbronchodilator); Oxygen Saturation
less than 90% on room air.
8. Pregnant and/or lactating women will be excluded due to the unknown, potentially
harmful effects of immune response to CT-X antigens and stem cell proteins that may be
expressed in placenta, fetus, and neonates.
9. Patients with active infections, including HIV, will be excluded, due to unknown
effects of the vaccine on lymphoid precursors.
