Summary
Brief summary (as posted)
Primary Objective: * To determine if there is significant toxicity associated with the administration of CD34-TK75 transduced donor lymphocytes after allogeneic BMT for relapsed hematologic malignancies Secondary Objectives: * To determine if the patient develops any evidence of anti-leukemic effect from the administration of CD34-TK75 transduced donor lymphocytes * To determine if ganciclovir administration to patients who develop Graft versus Host Disease (GVHD)results in clinical improvement after infusions of CD34-TK75 transduced lymphocytes. Sub-Study Objective The primary purpose is to perform PET imaging of CD34-TK transduced allogeneic donor T cells in patients who have relapsed hematologic malignancies after allogeneic hematopoietic stem cell transplantation (SCT). At this time the limited amount of cGMP quality virus produced by the NGVL will likely permit the imaging of only 3 patients. Consequently our current objective will be to establish that the TK-expressing cells can be detected by 18FHBG-PET in patient organs relevant for performing additional studies that are currently in the planning stages and for which we are working to produce additional virus. The ultimate objective will be to use the TK substrate 18FHBG to locate the donor T cells within the recipient as they exert anti-leukemic effects, and the T cells can then be eliminated in response to in vivo administration of ganciclovir, before morbidity and mortality from GvHD occurs. We will use the imaging strategy to define patterns of T cell trafficking in humans pre and post-DLI infusion, and to determine where the cells reside while they mediate GVL in contrast to GvHD. We expect to obtain in vivo PET imaging markers predictive of GvHD before clinical symptoms occur.

Inclusion Criteria for Patient: * Patients must be prior recipients of allogeneic BMT (matched 6/6 or 5/6 according to the National Marrow Donor Program) for any hematologic malignancy. Eligible patients would include those with leukemia, non Hodgkins Lymphoma, Hodgkins Disease, myelodysplastic syndrome and multiple myeloma. * Patients must have laboratory, histologic, or cytogenetic evidence of disease relapse after allogeneic BMT. * Patients may not have received prior therapy with transduced or non-transduced donor lymphocytes. * Patients ≥ 18 years of age. * The minimum number of transduced and purified lymphocytes from the same donor of donated cells for allogeneic transplant is is 1x105 per kg for all patients. * Expected survival of patient is at least 4 weeks. * Required baseline organ function within 14 days prior to study entry: * Renal function with creatinine less than 5 mg/dl. * Liver function with SGOT, SGPT and alkaline phosphatase ≤ 4 times the upper limit of institutional normal. * Bilirubin ≤ 5.0 mg/dl. * Patient must have signed the informed consent prior to entry and express willingness to meet all the expected requirements of the protocol for the duration of the study. * ECOG Performance Status ≤ 2 * All patients must agree to a repeat bone marrow, liver, gastro-intestinal or skin biopsies dependent on clinical course. * Women of child bearing potential must have a negative pregnancy test (ß-HCG ) within 7 days of study entry. * In addition patients # 3 to 8: * Must have consented to participation in HRPO 09-0744, "Infusion of Genetically Modified T cells: A Pilot I Study of Tracking and Toxicity * Must be willing to undergo 18FHBG-PET/CT-imaging * Must be able to tolerate 45-60 minutes of imaging at each imaging timepoint. * Women of child bearing potential must have an additional negative high sensitivity pregnancy test (20mlU ß-HCG /ml urine as administered in the Center for Clinical Imaging Research, Mallinckrodt Institute of Radiology, Washington University) prior to each imaging session (i.e. at days 10-16 and days 27-33). Inclusion Criteria for Donor: * Must be the original donor for the allogeneic bone marrow transplant patient. * No underlying conditions which would contra-indicate apheresis. * Must have signed the informed consent and express willingness to meet all the expected requirements stated in the protocol for the duration of the study. * Must be eligible according to Washington University "Guidelines for Eligibility of Normal Donors" * Donors ≥ 18 years of age. * Female donors of childbearing potential must have a confirmed negative pregnancy test. Exclusion Criteria for Patient: * Patients receiving immunosuppression (cyclosporin, FK506, prednisone, cellcept, methylprednisolone) for GvHD or other reasons at the time of lymphocyte infusion. * Patients must not have evidence of active CMV or other active viral infection requiring antiviral therapy.
