Summary
Background: - After allogeneic (donor) stem cell transplantation, a new immune system grows in the patient from the transplanted donor stem cells and lymphocytes (type of immune cell). Donor lymphocytes, unlike the patient s own lymphocytes, often can recognize the patient s tumor cells as being foreign and destroy them. - It is thought that tumor shrinkage after stem cell transplantation is the result of donor T lymphocytes, or T cells. Some studies show that patients with tumors that have T cells are better able to keep tumor growth in check. - Patients who have had donor stem cell transplantation may have donor T cells in their tumors that can recognize and fight their cancer. Compared with donor T cells taken directly from the donor and infused into the patient, donor T cells found in patients tumors may be specific for the cancer cells and thus better able to attack tumor. Also, because the T cells found their way to the tumor, they may be less likely to recognize and attack non-tumor tissues than the T cells given in donor lymphocyte infusions. - The T cells may be especially effective at controlling tumor if they are given an additional stimulus to become active. Costimulation is the name of the body s natural process for providing an extra stimulus, and can be performed on cells in the laboratory. Costimulation can produce large numbers of activated cells that may be able to attack cancer cells and shrink tumors. Objectives: -To evaluate the ability of lymphocytes found in tumors from patients who have received donor stem cell transplants to control their tumor growth. Eligibility: -Patients between 18 and 75 years of age with a B-cell cancer that has continued to grow or recurred after remission following allogeneic stem cell transplantation. This includes patients who have received transplants from unrelated donors and cord blood. Design: - Immune cells are collected from patients blood and blood from their stem cell donor. - Patients undergo surgery to remove their tumor and a small piece of skin. In the laboratory, donor T cells are isolated from the tumor and costimulated to expand the number of cells and activate them. - The expanded, activated T cells as infused into the patient. - Patients have a needle biopsy and possibly surgery to remove a sample of remaining tumor for research studies. - Patients are followed at the NIH clinic 48 hours after the cell infusion, and again at 1, 2, 4, 8 and 12 weeks after the infusion. Tumor size is monitored every month with CT scans, and possibly also with a PET or bone marrow aspiration and biopsy, for the first 3 months after the cells are infused. Thereafter, visits are less frequent (every 3 months, then every 6 months, and then yearly) during a minimum 5-year follow-up.

Criteria
- INCLUSION CRITERIA:

Recipient

1. Patients must have received allogeneic HSCT for B-cell malignancies (BCL),
specifically Hodgkin s and non-Hodgkin s lymphomas, chronic lymphocytic leukemias, non
T-cell acute lymphoblastic leukemia (B-cell ALL), or multiple myeloma, and must have
persistent disease that has failed to respond after a minimum of four weeks to:

2. Donor Engraftment Status: Patients must have had evidence of stable or increasing
donor engraftment over the preceding three months and at least 50% donor chimerism in
the bone marrow, whole blood and/or circulating CD3+ lymphoid pool.

3. A trial of withdrawal of immunosuppressive therapy, including trials that are
discontinued due to development of GVHD

4. Receiving at least one DLI with a minimum T cell dose of 1 x 10(7) CD3+ cells/kg.

- Patients who have persistent cancer after treatment with an alternative donor
alloHSCT (e.g., haploidentical, matched unrelated, umbilical cord blood) or any
patient for whom a donor cell product is unavailable and/or timely donor
collection is not feasible may be included without failing DLI.

- Presence of bone marrow involvement with tumor and/or at least one resectable
lymph node or other tumor focus that is a minimum of 1.5 cm(3) (estimated size
from which at least 1.0 x 106 TNC/kg can be generated):

5. Resectable defined on a case-by-case basis, in collaboration with the Surgical Consult
Service.

6. For surgical tumor resection, the expected procedure must be associated with minimal
morbidity and minimal hospitalization.

7. In addition to a resectable lesion, there must be at least one other site of disease
that permits monitoring for response to therapy.

8. Patients must be 18 75 years of age.

9. ECOG performance status less than or equal to 2 (Karnofsky performance status greater
than or equal to 60%).

10. Life expectancy > 3 months.

11. Minimal to no clinical evidence (Grade 0 to 1) of acute GVHD or limited-stage chronic
GVHD while off of systemic immunosuppressive therapy for at least four weeks. Subjects
who require continued prophylaxis with steroid-sparing agents, e.g.,cyclosporine, or
whose disease is controlled with local therapy, e.g., topical steroids or budesonide,
will be eligible for enrollment.

12. Provision for a Durable Power of Attorney.

13. Ability to give informed consent.

1.4 Eligibility of Recipients is not contingent upon enrollment of the donor.

Donor

Note: Donor enrollment is not required to meet the primary objectives of this protocol and
will not affect eligibility of recipients.

1. Donor 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 apheresis, or consent to use a temporary central
venous catheter for apheresis.

3. Donors must be HIV negative, hepatitis B surface antigen negative, and hepatitis C
antibody negative.

EXCLUSION CRITERIA:

Recipients

1. Active infection that is not responding to antimicrobial therapy.

2. Active psychiatric disorder which may compromise compliance with transplant protocol,
or which does not allow for appropriate informed consent (as determined by Principal
Investigator and/or his designee).

3. Pregnant or lactating. Patients of childbearing potential must use an effective method
of contraception. 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.

4. 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. 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 prothombin time >2 time the upper limit of normal).

5. Minimum absolute neutrophil count of 500 cells/microl, unless attributable to tumor.

6. Untreated leptomeningeal involvement with malignancy.

Donors:

1. History of psychiatric disorder which may compromise compliance with transplant
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. Donors of childbearing potential must use an effective
method of contraception.

4. Anemia (Hb < 11 gm/dl) or thrombocytopenia (platelets < 100,000 per microl). 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 will determine the appropriateness
of individuals as donors.
