Somministrazione di cellule T trasdotte dal recettore dell'antigene chimerico anti-CD19 dal donatore di trapianto originale a pazienti con tumori maligni delle cellule B ricorrenti o persistenti dopo trapianto di cellule staminali allogeniche

• INCLUSION CRITERIA:

Inclusion Criteria: Recipient

1. Recipients (patients with B-cell malignancy) must have received an HLA-identical or 9/10 matched sibling allogeneic hematopoietic stem cell transplant, or a greater than or equal to 9/10-matched unrelated donor (URD) alloHSCT for any CD19+ B-cell malignancy. Haploidentical donors will not be used in this protocol. Patients with any CD19+ B-cell malignancy that is persistent or relapsed after all of the following interventions are eligible:

   1. Donor engraftment after alloHSCT (>50% donor chimerism of the blood T cells or whole blood leukocytes or whole bone marrow).
   2. A trial of withdrawal of immunosuppressive therapy.

   NOTE: At least 28 days must have elapsed since the latest trial of withdraw of immunosuppression or DCI until the patient can be deemed to have persistent disease.

2. CD19 expression must be detected on the majority of the malignant cells by immunohistochemistry or by flow cytometry in the Laboratory of Pathology, CCR, NCI, NIH. Definition of which cells are malignant must be determined for each patient by the Laboratory of Pathology using techniques to demonstrate monoclonality such as kappa/lambda restriction (other techniques can be used to determine monoclonality at the discretion of the Laboratory of Pathology). The choice of whether to use flow cytometry or immuohistochemistry will be determined by what is the most easily available tissue sample in each patient. Immunohistochemistry will be used for lymph node biopsies and bone marrow biopsies. Flow cytometry will be used for peripheral blood, fine needle aspirate, and bone marrow aspirate samples.

3. Patients must be 18-75 years of age.

4. Performance status: ECOG less than or equal to 2

5. Either no evidence of GVHD or minimal clinical evidence of acute GVHD and chronic GVHD while off of systemic immunosuppressive therapy for at least 28 days. Minimal clinical evidence of acute GVHD is defined as grade 0 to I acute GVHD. Minimal evidence of chronic GVHD is defined as chronic GVHD with no organ site with a score exceeding 1, except for the skin, for which a score of 1 or 2 will be allowable (as defined by the 2005 NIH consensus project) or no chronic GVHD. Subjects with disease that is controlled to stage I acute GVHD or chronic GVHD meeting the above criteria with local therapy only, e.g., topical cutaneous steroids, will be eligible for enrollment.

6. Ability to give informed consent.

7. Prior Therapy: Therapy with monoclonal antibodies and/or chemotherapy must be stopped at least 14 days prior to anti-CD19 CAR-transduced T cell infusion, and recovery of treatment-associated toxicity to less than or equal to grade 2 is required prior to infusion of cells. For patients that have received prior DCI, the last dose must be at least 28 days prior to anti-CD19 CAR-transduced T cell administration. Note that patients can be enrolled on this study at any time after or during therapy, but at least 14 days must elapse from the time of prior monoclonal antibody administration or chemotherapy until anti-CD19 CAR-transduced T cells are infused, and at least 28 days must elapse from the time of withdraw of immunosuppression, or DCI, or other immunomodulatory therapies such as lenalidomide until anti-CD19 CAR-transduced T cells are infused. Systemic immunosuppression given for graft versus host disease must be stopped at least 28 days prior to protocol entry. There is no time restriction in regard to prior intrathecal chemotherapy provided there is complete recovery from any acute toxic effects of such.

8. Recipients of unrelated donor transplants from a National Marrow Donor Program (NMDP) Center must sign a release of information form to authorize NMDP transfer of information to the NIH.

9. Previous allogeneic donor must be willing and available to donate again.

10. Patients of childbearing or child-fathering potential must be willing use an effective method of contraception while being treated on this study and for 4 months after the last cell infusion.

11. Normal left ventricular function as evaluated by echocardiograph within 4 weeks of protocol therapy

Inclusion Criteria: Donor

1. Donors greater than or equal to 18 years of age must be the same individual whose cells were used as the source for the patient s original stem cell transplant.
2. Adequate venous access for peripheral leukapheresis, or consent to use a temporary central venous catheter for leukapheresis.
3. Donors must be HIV negative, hepatitis B surface antigen negative, and hepatitis C antibody negative.
4. Ability to give informed consent.
5. Donor selection will be in accordance with NIH/CC Department of Transfusion Medicine (DTM) criteria and, in the case of an unrelated donor from a Transplant Center, the National Marrow Donor Program (NMDP) standards. When a potentially eligible recipient of an unrelated donor product from an NMDP Center is identified, the recipient will complete an NMDP search transfer request to allow NIH NMDP staff to contact the NMDP Coordinating Center, who will, in turn, contact the donor s prior Donor Center. The NMDP Policy for Subsequent Donation Requests will be followed and the appropriate forms (Subsequent Donation Request form) and Therapeutic T Cell Collection Prescription will be submitted as required.

EXCLUSION CRITERIA:

Exclusion Criteria: Recipients

1. Active infection that is not responding to antimicrobial therapy.
2. Sero positive for 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 are less responsive to the experimental treatment and more susceptible to its toxicities.)
3. Sero positive for hepatitis B antigen, positive hepatitis B tests can be further evaluated by confirmatory tests (HBV DNA), and if confirmatory tests are negative, the patient can be enrolled.
4. Sero positive for hepatitis C antibody unless antigen negative. If hepatitis C antibody test is positive, then patients must be tested for the presence of RNA by RT-PCR and be HCV RNA negative.
5. Active psychiatric disorder which may compromise compliance with the treatment protocol, or which does not allow for appropriate informed consent (as determined by Principal Investigator and/or his designee).
6. Pregnant or lactating. The effects of the immunosuppressive medications that could be required to treat GHVD are likely to be harmful to a fetus. The effects upon breast milk are also unknown and may be harmful to an infant.
7. Serum total bilirubin > 2.5 mg/dl, serum ALT and AST values greater than or equal to 2.5 times the upper limit of normal based on age-specific normal values. If the abnormal liver function is attributable to liver involvement by malignancy, patients may be eligible with serum total bilirubin up to 5.0 mg/dl, and serum ALT and AST values up to 5.0 times the upper limit of normal, provided the patient has no evidence of impending hepatic failure (encephalopathy or prothrombin time >2 time the upper limit of normal).
8. Serum creatinine greater than 1.6 mg/dL
9. Absolute neutrophil count of less than 1000 cells/ml unless low neutrophil count is thought to be due to malignancy in the bone marrow and malignancy is documented in the bone marrow.
10. Active cerebrospinal fluid involvement with malignancy or brain metastasis.
11. Platelet count less than 30,000/ml unless low platelet count is thought to be due to malignancy in the bone marrow and malignancy is documented in the bone marrow.
12. Hemoglobin less than 8.0 g/dL.
13. Receiving systemic corticosteroids including prednisone, dexamethasone or any other corticosteroid at doses of higher than 5 mg/day of prednisone within 28 days prior to anti-CD19-CAR-transduced T cell administration. Corticosteroid creams, ointments, and eye drops are allowed.
14. Blood blast percentage higher than 5%.

Exclusion Criteria: Donors

1. History of psychiatric disorder which may compromise compliance with this protocol or which does not allow for appropriate informed consent.
2. History of hypertension that is not controlled by medication, stroke, or severe heart disease (donors with symptomatic angina will be excluded). Donors with a history of coronary artery bypass grafting or angioplasty who are symptom free will receive a cardiology evaluation and be considered on a case-by-case basis.
3. Donors must not be pregnant.
4. Anemia (Hb < 11 gm/dl) or thrombocytopenia (platelets < 100,000 per ml). However, potential donors with Hb levels < 11 gm/dl that is due to iron deficiency will be eligible as long as the donor is initiated on iron replacement therapy. The NIH Clinical Center, Department of Transfusion Medicine/NMDP physicians will determine the appropriateness of individuals as donors.
