Phase I/II Study Using Prophylactic Donor Lymphocyte Infusion Early Post-Transplant After Allogeneic Hematopoietic Cell Transplantation Using Post-Transplantation Cyclophosphamide for High-Risk Hematologic Malignancies

Description

Background: People with blood cancers often receive blood or bone marrow transplants. But even with these treatments, the risk of relapse is high. Researchers want to see if giving the transplant recipient an infusion of lymphocytes (a type of white blood cell) from their transplant donor early after the transplant can reduce that risk. Objective: To learn if giving donor lymphocytes early after a transplant will help reduce the risk of relapse for people with certain blood cancers. Eligibility: Adults aged 18-65 with high-risk leukemia, lymphoma, myelodysplastic syndrome, or multiple myeloma that does not respond well to standard treatments and/or has a high risk of relapse. Healthy potential bone marrow and lymphocyte donor relatives aged 12 and older are also needed. Design: Participants will be screened with: Physical exam Blood and urine tests Spinal tap Eye exam Dental exam Heart and lung tests Imaging scans. A radioactive substance may be injected in their arm if a

Trial Eligibility

* INCLUSION CRITERIA: Inclusion Criteria - Recipient * Histologically or cytologically confirmed hematologic malignancy classified as high or very high disease risk by the Refined Disease Risk Index for HCT including one of the following: * Acute myeloid leukemia (AML) with favorable cytogenetics (t(8;21), inv(16), t(15,17)) with induction failure (persistent disease without first achieving remission of any type) or active relapse * AML with intermediate cytogenetics (not classified as favorable or adverse) with induction failure or active relapse (AML with intermediate cytogenetics in morphologic complete remission \[CR\] with minimal residual disease detectable by any modality also will be eligible) * AML with adverse cytogenetics (complex karyotype with \>= 4 abnormalities) regardless of remission status * Low risk myelodysplastic syndrome (MDS) (\<= 5% blasts, including chronic myelomonocytic leukemia) with adverse cytogenetics (abnormal chromosome 7 or \>= 4 abnormalities) with induction failure or active relapse * High risk MDS (RAEB-1 or RAEB-2) with intermediate-risk cytogenetics (no abnormal chromosome 7 or \< 4 abnormalities) with induction failure or active relapse * High risk MDS (RAEB-1 or RAEB-2) with adverse cytogenetics (abnormal chromosome 7 or \>= 4 abnormalities) regardless of remission status * Acute lymphoblastic leukemia (ALL) in CR \>= 2 or with induction failure or active relapse (ALL in CR1 with minimal residual disease detected also will be eligible) * Chronic myelocytic leukemia (CML) in blast crisis phase * Hodgkin lymphoma with stable or progressive disease * Mantle cell lymphoma with stable or progressive disease * Relapsed Burkitt lymphoma in CR or partial remission (PR) * Aggressive B-cell Non-Hodgkin Lymphoma (NHL) (e.g., diffuse large B-cell lymphoma, transformed indolent B-cell lymphoma) with stable or progressive disease * T-cell NHL with stable or progressive disease * Multiple myeloma (MM) with induction failure as defined by failure to achieve minimal response (CR, Very Good Partial Response \[VGPR\], or PR) or the development of progressive disease on primary therapy, or MM with active relapse as defined by previously treated myeloma that achieved a molecular response or better that then progressed * Age 18-65 years. * At least one potentially suitable HLA-haploidentical or HLA-matched donor * Karnofsky performance score \>=60% * Recipient participants must have adequate organ function as defined below: * Cardiac ejection fraction \>=45% by 2D ECHO; * Forced expiratory volume-1 (FEV-1), forced vital capacity (FVC), and diffusing capacity of the lung for carbon monoxide (DLCO) (corrected for hemoglobin) all of \>=50% predicted; * Estimated serum creatinine clearance of \>=60 ml/minute/1.73m2 calculated using eGFR in the clinical lab; * Total bilirubin \<=2X the upper limit of normal; * Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) \<=3X the upper limit of normal. * Myeloablative conditioning is toxic to the developing human fetus and is teratogenic. For this reason, the following measures apply: * Women of child-bearing potential (WOCBP) and men must agree to use highly effective contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for at least one-year post-transplant. * WOCBP must have a negative serum or urine pregnancy test within 7 days prior to enrollment. Inclusion Criteria - Donor -Related donor (age \>=12) deemed suitable, eligible, and willing to donate, per clinical evaluations, who are additionally willing to donate blood, bone marrow, and stool for research. Related donors will be evaluated in accordance with existing Standard Policies and Procedures for determination of eligibility and suitability for clinical donation. EXCLUSION CRITERIA: Exclusion Criteria - Recipient * Subjects who are receiving any other investigational agents. Prior experimental therapies must have been completed at least 3 weeks prior to the date of beginning conditioning. * Prior myeloablative conditioning for autologous or allogeneic HCT. * Active breastfeeding. * Active malignancy of non-hematopoietic type (excluding non-melanoma skin cancers) which is metastatic, relapsed/refractory to treatment, or locally advanced and not amenable to curative treatment. This excludes non-melanoma skin cancers. * Uncontrolled intercurrent illness (e.g. severe endocrinopathy, disseminated intravascular coagulation, profound electrolyte disturbance, active hepatitis, uncontrolled dental infection) that in the opinion of the PI would make it unsafe to proceed with transplantation. Exclusion Criteria - Donor None.
