Background:
During recent years, cancer-testis (CT) antigens (CTA), particularly those encoded by genes
on the X chromosome (CT-X genes), have emerged as attractive targets for cancer
immunotherapy. Whereas malignancies of diverse histologies express a variety of CTAs, immune
responses to these proteins appear uncommon in cancer patients, possibly due to low-level,
heterogeneous antigen expression, as well as immunosuppressive regulatory T cells present
within tumor sites and systemic circulation of these individuals. Conceivably, vaccination of
cancer patients with tumor cells expressing high levels of CTAs in combination with regimens
that deplete or inhibit T regulatory cells will induce broad immunity to these antigens. In
order to examine this issue, patients with primary lung and esophageal cancers, pleural
mesotheliomas, thoracic sarcomas, thymic neoplasms and mediastinal germ cell tumors, as well
as sarcomas, melanomas, germ cell tumors, or epithelial malignancies metastatic to lungs,
pleura or mediastinum with no evidence of disease (NED) or minimal residual disease (MRD)
following standard multidisciplinary therapy will be vaccinated with H1299 tumor cell lysates
with Iscomatrix adjuvant. Vaccines will be administered with or without 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 as well as immunologic responses to autologous
tumor or epigenetically modified autologous EBVtransformed lymphocytes will be assessed
before and after a six month vaccination period.
Primary Objectives:
1. To assess the frequency of immunologic responses to CTAs in patients with thoracic
malignancies following vaccinations with H1299 cell lysate/Iscomatrix(TM) vaccines alone in
comparison to patients with thoracic malignancies following vaccinations with H1299 cell
lysate/Iscomatrix vaccines in combination with metronomic cyclophosphamide and celecoxib.
Secondary Objectives:
1. To examine if oral metronomic cyclophosphamide and celecoxib therapy diminishes the
number and percentage of T regulatory cells and diminishes activity of these cells in
patients with thoracic malignancies are at risk of recurrence.
2. To examine if H1299 cell lysate/Iscomatrix(TM) vaccination enhances immunologic response
to autologous tumor or epigenetically modified autologous EBV-transformed lymphocytes (B
cells).
Eligibility:
- Patients with histologically or cytologically proven small cell or non-small cell lung
cancer (SCLC;NSCLC), esophageal cancer (EsC), malignant pleural mesothelioma (MPM) ,
thymic or mediastinal germ cell tumors, thoracic sarcomas, or melanomas, sarcomas, or
epithelial malignancies metastatic to lungs, pleura or mediastinum who have no clinical
evidence of active disease (NED), or minimal residual disease (MRD) not readily
accessible by non-invasive biopsy or resection/radiation following standard therapy
completed within the past 26 weeks.
- Patients must be 18 years or older with an ECOG performance status of 0 2.
- Patients must have adequate bone marrow, kidney, liver, lung and cardiac function.
- Patients may not be on systemic immunosuppressive medications at time vaccinations
commence
Design:
- Following recovery from surgery, chemotherapy, or chemo/XRT, patients with NED or MRD
will be vaccinated via IM injection with H1299 cell lysates and Iscomatrix(TM) adjuvant
monthly for 6 months.
- Vaccines will be administered with or without with metronomic oral cyclophosphamide and
celecoxib.
- Systemic toxicities and immunologic response to therapy will be recorded. Pre and post
vaccination serologic and cell mediated responses to a standard panel of CT antigens as
well as autologous tumor cells (if available) and EBV-transformed lymphocytes 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.
- The trial will randomize 28 evaluable patients per arm to either receive vaccine alone
or vaccine plus chemotherapy in order to have 80% power to determine if the frequency of
immune responses on the combination arm exceeds that of the vaccine alone arm, if the
expected frequencies of immune responses on the two arms were 20% and 50%, using a
one-sided 0.10 alpha level Fisher s exact test.
- Approximately 60 patients will be accrued to this trial.

excluded: FEV, < 30% predicted; DLCO < 30% predicted (post-bronchodilator); oxygen
saturation less than 92% on room air.
2.1.2.7 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.
2.1.2.8 Patients with active infections, including HIV, will be excluded, due to unknown
effects of the vaccine on lymphoid precursors.
2.1.2.9 Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, or psychiatric illness/social situations 3 months prior to enrollment that
