Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

Background: Stem cell or bone marrow transplants can cure or control blood cancers. Sometimes the donor cells see the recipient's body as foreign. This can cause complications. A high dose of the drug cyclophosphamide (PTCy) can help reduce these risks. Researchers want to see if a lower dose of PTCy can have the same benefits. Based on encouraging results from the first part of the study, researchers now are investigating whether a lower dose of PTCy can allow other immunosuppression to be decreased. Objective: To see if a lower dose of PTCy and now also shorter duration of another immunosuppressant called mycophenolate mofetil will help people with blood cancers have a more successful transplant and fewer side effects. Eligibility: People ages 15-65 with leukemia, lymphoma, or multiple myeloma that is not curable with standard therapy and is at high risk of returning without transplant, and their healthy adult relatives Design: Transplant participants will be screened with: Blood, urine, breathing, and heart tests Scans Chest x-ray Bone marrow samples: A needle inserted into the participant s pelvis will remove marrow and a bone fragment. Transplant recipients will stay at the hospital and be prepped with chemotherapy over 6 days for the transplant. They will get stem cells through a catheter in the chest or neck. They will get the cyclophosphamide chemotherapy. They will stay in the hospital about 4 more weeks. They will have blood transfusions. They will have frequent blood tests and 2 bone marrow samples within 1 year after the transplant. Donor participants will be screened with: Blood, urine, and heart tests Chest x-ray Scans Donor participants will have bone marrow taken from their pelvis or stem cells taken from their blood. For the blood donation, blood will be taken from a vein in one arm, move through a machine to remove white blood cells, and be returned through a vein in the other arm. Participation will last up to 5 years....

Inclusion Criteria	Exclusion Criteria
* Patients must have a histologically or cytologically confirmed hematologic malignancy with standard indication for allogeneic hematopoietic cell transplantation limited to one of the following: * Acute myeloid leukemia (AML) of intermediate or adverse risk disease by the 2017 European LeukemiaNet criteria in first morphologic complete remission (\<5% blasts in the bone marrow, no detectable abnormal peripheral blasts, and no extramedullary disease) * AML of any risk in second or subsequent morphologic complete remission * B-cell acute lymphoblastic leukemia in first or subsequent complete remission * T-cell acute lymphoblastic leukemia with minimal residual disease detected after first line therapy and/or adverse genetics (no NOTCH1/FBXW7 mutation or presence of N/K-RAS mutation and/or PTEN gene alteration) * Myelodysplastic syndrome of intermediate or higher score by the Revised International Prognostic Scoring System (IPSS-R) * Primary myelofibrosis of intermediate-2 or higher risk by the DIPSS * Chronic myelomonocytic leukemia * Chronic myelogenous leukemia resistant to or intolerant of \>=3 tyrosine kinase inhibitors or with history of accelerated phase or blast crisis * B-cell lymphoma including Hodgkin lymphoma that has relapsed within 1 year of completion of primary treatment * Chronic lymphocytic leukemia with 17p deletion and/or unmutated IgHV or refractory to or intolerant of both BTK and PI3K inhibitors * Mature T or NK neoplasms as defined in the WHO guidelines of sufficient type and severity for allogeneic HCT based on the Prognostic Index for T-cell lymphoma (PIT) score of low-intermediate risk or higher or on recently published clinical practice guidelines * Hematologic malignancy of dendritic cell or histiocytic cell type * Multiple myeloma, stage III, relapsing after therapy with both a proteasome inhibitor and an immunomodulatory drug (IMiD) * Age 15-65. Patients \<18 years old must be at least 50 kg. Note: Because patients 15-17 years old and \<50 kg are not able to be cared for on the adult oncology wards and by the investigative team, they are excluded. * At least one potentially suitable HLA-haploidentical donor. * Karnofsky performance score \>=60 * Adequate organ function defined as possessing all of the following: * 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/1.73m\^2 calculated using eGRF in the clinical lab for adults and the Schwartz formula for pediatric subjects; * Total bilirubin \<=2X the upper limit of normal; * Alanine aminotransferase and aspartate aminotransferase \<=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: * Individuals of child-bearing potential (IOCBP) and participants who can father children must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for at least one year post-transplant. * IOCBP must have a negative serum or urine pregnancy test within 7 days prior to enrollment. * Ability of subject or Legally Authorized Representative to understand and the willingness to sign a written informed consent document. Pediatric patients (\<18 years of age) will provide assent, and the parent(s) or legal guardian(s) will provide informed consent. * Subjects requiring standard therapies to prepare for HCT should be referred in remission if possible. However, these diseases are often aggressive and require swift evaluation for HCT while concurrently attempting to establish disease control through the administration of standard therapies. If ongoing therapy for the underlying disease outside of the NIH is not in the best interest of the subject according to the clinical judgment of the PI, then the subject may receive up to 2 cycles of standard treatment for his/her underlying hematologic malignancy as a bridge to HCT on this protocol, prior to starting the research phase of the study. The subject must have a Karnofsky performance status of \>= 60% at the start of the first cycle to proceed. If it becomes apparent that the subject will not be able to proceed to HCT, then he/she must come off study. Subjects receiving standard therapy will be told about the therapy, associated risks, potential benefits, alternatives to the proposed therapy, and the availability of receiving the same treatment elsewhere, outside of a research protocol.	* Patients who are receiving any other investigational agents. Prior experimental therapies must have been completed at least 4 weeks prior to the date of beginning conditioning. * Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection excluding controlled fungal infection on appropriate treatment, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, endocrinopathy (significant uncontrolled or untreated hypothyroidism, hyperthyroidism, or adrenal insufficiency), or active psychiatric illness/social situations that would limit compliance with study requirements * Prior myeloablative conditioning for autologous or allogeneic HCT. * An HLA-matched-sibling donor who is available and willing to donate bone marrow. Note: The patient must have access to HCT using this donor for this to be an exclusion criterion. * Individuals who are pregnant or who intend to become pregnant during the study are excluded because myeloablative conditioning is toxic to the developing fetus with the potential for teratogenic or abortifacient effects. * Nursing participants must be willing to discontinue nursing at the time of the study treatment initiation, as the potential for some of the study medications to be transmissible via nursing is unknown. * Active malignancy of non-hematopoietic type (excluding non-melanoma skin cancers) which is: metastatic, or relapsed/refractory to treatment, or locally advanced and not amenable to curative treatment, or limited disease treated with curative intent treatment within the last 2 years. This excludes non-melanoma skin cancers. * The severity of the hematologic malignancy does not warrant the potential toxicity of myeloablative allogeneic HCT as judged by the PI.
