Summary
Brief summary (as posted)
Background: The National Cancer Institute (NCI) Surgery Branch has developed an experimental therapy for treating patients with metastatic cancer that involves taking white blood cells from the patient, growing them in the laboratory in large numbers, genetically modifying these specific cells with a type of virus (retrovirus) to attack only the tumor cells, and then giving the cells back to the patient. This type of therapy is called gene transfer. In this protocol, we are modifying the patients white blood cells with a retrovirus that has the gene for anti-mesothelin incorporated in the retrovirus. Objective: The purpose of this study is to determine a safe number of these cells to infuse and to see if these tumor fighting cells (anti-mesothelin cells) cause metastatic cancer tumors to shrink. Eligibility: \- Adults age 18-70 with metastatic cancer expressing the mesothelin molecule. Design: Work up stage: Patients will be seen as an outpatient at the National Institutes of Health (NIH) clinical Center and undergo a history and physical examination, scans, x-rays, lab tests, and other tests as needed Leukapheresis: If the patients meet all of the requirements for the study they will undergo leukapheresis to obtain white blood cells to make the anti-mesothelin cells. {Leukapheresis is a common procedure, which removes only the white blood cells from the patient.} Treatment: Once their cells have grown, the patients will be admitted to the hospital for the conditioning chemotherapy, the anti-mesothelin cells, and aldesleukin. They will stay in the hospital for about 4 weeks for the treatment. Follow up: Patients will return to the clinic for a physical exam, review of side effects, lab tests, and scans about every 1-3 months for the first year, and then every 6 months to 1 year as long as their tumors are shrinking. Follow up visits will take up to 2 days.

* INCLUSION CRITERIA:
1. Metastatic or unresectable measurable cancers that express mesothelin. As in other protocols conducted by Dr. Hassan in the National Cancer Institute (NCI), epithelial mesotheliomas and pancreatic cancers do not need to be assessed for mesothelin expression since all of these tumors have been shown to express mesothelin. Other metastatic or unresectable cancers must be shown to expresses mesothelin as assessed by reverse transcription polymerase chain reaction (RT-PCR) or immunohistochemistry on tumor tissue. Bi-phasic mesotheliomas must express mesothelin on greater than 50% of the cells in the epithelial component. Diagnosis will be confirmed by the Laboratory of Pathology, NCI.
2. Patients must have previously received at least one systemic standard care (or effective salvage chemotherapy regimens) for metastatic or unresectable disease, if known to be effective for that disease, and have been either non-responders (progressive disease) or have recurred.
3. Greater than or equal to 18 years of age and less than or equal to 70 years of age.
4. Willing to sign a durable power of attorney
5. Able to understand and sign the Informed Consent Document
6. Clinical performance status of Eastern Cooperative Oncology Group (ECOG) 0 or 1.
7. Patients of both genders must be willing to practice birth control from the time of enrollment on this study and for up to four months after treatment.
8. Serology:
1. Seronegative for human immunodeficiency virus (HIV) antibody. (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 be less responsive to the experimental treatment and more susceptible to its toxicities.)
2. Seronegative for hepatitis B antigen, and seronegative for hepatitis C antibody. If hepatitis C antibody test is positive, then patient must be tested for the presence of antigen by RT-PCR and be Hepatitis C virus ribonucleic acid (HCV RNA) negative.
9. Women of child-bearing potential must have a negative pregnancy test because of the potentially dangerous effects of the treatment on the fetus.
10. Hematology:
1. Absolute neutrophil count greater than 1000/mm(3) without the support of filgrastim.
2. White blood cell (WBC) (\> 3000/mm(3)).
3. Platelet count greater than 100,000/mm(3).
4. Hemoglobin greater than 8.0 g/dl.
11. Chemistry:
1. Serum alanine aminotransferase/aspartate aminotransferase (ALT/AST) less or equal to 2.5 times the upper limit of normal.
2. Serum creatinine less than or equal to 1.6 mg/dl.
3. Total bilirubin less than or equal to 1.5 mg/dl, except in patients with Gilbert's Syndrome who must have a total bilirubin less than 3.0 mg/dl.
12. More than four weeks must have elapsed since any prior systemic therapy at the time the patient receives the preparative regimen, and patient's toxicities must have recovered to a grade 1 or less (except for toxicities such as alopecia or vitiligo).
Note: Patients may have undergone minor surgical procedures within the past 3 weeks, as long as all toxicities have recovered to grade 1 or less.
13. Subject's must be co-enrolled in protocol 03-C-0277.
EXCLUSION CRITERIA:
1. Patients with sarcomatoid mesothelioma as mesothelin is not expressed in this type of mesothelioma.
2. Women of child-bearing potential who are pregnant or breastfeeding because of the potentially dangerous effects of the treatment on the fetus or infant.
3. Patients with known brain metastases.
4. Patients receiving full dose anticoagulative therapy.
5. Active systemic infections (e.g.: requiring anti-infective treatment), coagulation disorders or any other major medical illnesses.
6. Any form of primary immunodeficiency (such as Severe Combined Immunodeficiency Disease).
7. Concurrent opportunistic infections (The experimental treatment being evaluated in this protocol depends on an intact immune system. Patients who have decreased immune competence may be less responsive to the experimental treatment and more susceptible to its toxicities).
8. Patients with diabetic retinopathy.
9. Concurrent Systemic steroid therapy.
10. History of severe immediate hypersensitivity reaction to any of the agents used in this study.
11. History of coronary revascularization or ischemic symptoms.
12. Documented left ventricular ejection fraction (LVEF) of less than or equal to 45% tested in patients with:
* Clinically significant atrial and/or ventricular arrhythmias including but not limited to: atrial fibrillation, ventricular tachycardia, second- or third-degree heart block, chest pain, or ischemic heart disease
* Age greater than or equal to 65 years old
13. Documented forced expiratory volume 1 (FEV1) less than or equal to 60% predicted tested in patients with:
* A prolonged history of cigarette smoking (20 pk/year of smoking within the past 2 years).
* Symptoms of respiratory dysfunction
14. Patients who are receiving any other investigational agents.References
