- Certain types of lung, esophageal, or thymic cancers and mesotheliomas have specific antigens (protein molecules) on their surfaces. Research studies have shown that giving a vaccine that contains antigens similar to these may cause an immune response, which may keep tumors from growing. Researchers are also interested in determining whether the chemotherapy drug cyclophosphamide and the anti-inflammatory drug celecoxib may help the vaccine work better, particularly in patients with lung cancer.
- To evaluate the safety and effectiveness of tumor cell vaccines in combination with cyclophosphamide and celecoxib in patients with cancers involving the chest.
- Individuals at least 18 years of age who have had surgery for small cell or non-small cell lung cancer, esophageal cancer, thymoma or thymic carcinoma, and malignant pleural mesothelioma.
- Following recovery from surgery, chemotherapy, or radiation, participants will have leukapheresis to collect lymphocytes (white blood cells) for testing.
- Participants will receive celecoxib and cyclophosphamide to take twice a day at home, 7 days before the vaccine.
- Participants will have the vaccine in the clinical center (one or two shots per month for 6 months), and will stay in the clinic for about 4 hours after the vaccine. Participants will keep a diary at home of any side effects from the vaccine, and will continue to take cyclophosphamide and celecoxib.
- One month after the sixth vaccine, participants will provide another blood sample for testing, and if the tests are satisfactory will return to the clinic every 3 months for 2 additional vaccines.
- Participants will return to clinic for follow-up physical examinations, lab tests, and scans every 3 months for 2 years and then every 6 months for up to 3 years.

- Tabulation of toxicity type and grade [ Time Frame: 2 years ]If 25 patients are enrolled and the true probability of a grade 3 or worse toxicity (of any sort) were 20%, then the probability of having 4 or more patients with this occurring is 76.6%. On the other hand, if the combination was very safe and the true probability of a grade 3 or worse toxicity was 5%, then the probability of having 4 or more patients with this occurring would be 3.4%. Thus, if 25 patients were treated, the combination may be considered to have potentially lower safety than tolerable if 4 or more patients experience grade 3 or worse toxicity.
- To ascertain if K526-GM vaccines induce immunity to CT antigens commonly expressed in thoracic malignancies. [ Time Frame: 2 years ]Perform exploratory analyses which investigate immunologic responses to a panel of CT antigens in vaccinated patients.
- To determine if metronomic oral CP and celecoxib reduce the number, percentage and function of CD4+ CD25+ Fox P3+ regulatory T cells (T reg) in peripheral blood of thoracic oncology patients. [ Time Frame: 2 years ]Measure T regulatory cells at baseline and at the conclusion of treatment. The difference, or the relative difference, in the values at the two time points will be obtained, and tested to determine if the difference is equal to zero. If a paired t-test is able to be used, with at least 20 evaluable patients, there is 81% power to detect a change equal to 3/4ths of a standard deviation of the change at the two-sided 0.025 significance level.
