The purpose of this study is to find out if there is a benefit to giving rituximab with etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin (R-EPOCH) in participants who have high-risk B-cell PTLD in their 2nd phase of treatment (consolidation) while those with low-risk disease will be spared of chemotherapy and treated with rituximab consolidation alone. This study is also being done to find out about the usefulness of circulating tumor DNA (ctDNA), a novel blood test which, has been shown to help guide treatment decisions in other types of lymphoma. The goal is to answer the question if ctDNA is a viable and informative tool in treating PTLD with the hope that in the future it may be used to individualize study treatment for participants with PTLD in a way that limits study treatment toxicity without losing the effectiveness of the treatment plan.

This phase II trial studies how well naive T-cell depletion works in preventing chronic graft-versus-host disease in children and young adults with blood cancers undergoing donor stem cell transplant. Sometimes the transplanted white blood cells from a donor attack the body's normal tissues (called graft versus host disease). Removing a particular type of T cell (naive T cells) from the donor cells before the transplant may stop this from happening. Read Less

This phase I trial tests the safety, side effects, and best dose of autologous anti-CD19 CAR-expressing T lymphocytes (CD19-CAR T cells) in older adults with B-cell acute lymphoblastic leukemia. Chimeric antigen receptor (CAR) T-cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's cancer cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of B-cell acute lymphoblastic leukemia. Read Less

Blood stem cells can produce red blood cells (which carry oxygen), white blood cells of the immune system (which fight infections) and platelets (which help the blood clot). Patients with sickle cell disease produce abnormal red blood cells. A blood stem cell transplant from a donor is a treatment option for patients with severe sickle cell disease. The donor can be healthy or have the sickle cell trait. The blood stem cell transplant will be given to the patient as an intravenous infusion (IV). The donor blood stem cells will then make normal red blood cells - as well as other types of blood cells - in the patient. When blood cells from two people co-exist in the patient, this is called mixed chimerism. Most children are successfully treated with blood stem cells from a sibling (brother/sister) who completely shares their tissue type (full-matched donor). However, transplant is not an option for patients who (1) have serious medical problems, and/or (2) do not have a full-matched donor. Most patients will have a relative who shares half of their tissue type (e.g. parent, child, and brother/sister) and can be a donor (half-matched or haploidentical donor). Adult patients with severe sickle cell disease were successfully treated with a half-matched transplant in a clinical study. Researchers would like to make half-matched transplant an option for more patients by (1) improving transplant success and (2) reducing transplanted-related complications. This research transplant is being tested in this Pilot study for the first time. It is different from a standard transplant because: 1. Half-matched related donors will be used, and 2. A new combination of drugs (chemotherapy) that does not completely wipe out the bone marrow cells (non-myeloablative treatment) will be used to prepare the patient for transplant, and 3. Most of the donor CD4+ T cells (a type of immune cells) will be removed (depleted) before giving the blood stem cell transplant to the patient to improve transplant outcomes. It is hoped that the research transplant: 1. Will reverse sickle cell disease and improve patient quality of life, 2. Will reduce side effects and help the patient recover faster from the transplant, 3. Help the patient keep the transplant longer and 4. Reduce serious transplant-related complications. Read Less

This phase I trial investigates the side effects of chemotherapy and cellular immunotherapy in treating children with IL13Ralpha2 positive brain tumors that have come back after a period of improvement (recurrent) or do not respond to treatment (refractory). Cellular immunotherapy (IL13(EQ)BBzeta/CD19t+ T cells) are brain-tumor specific cells that may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as as cyclophosphamide and fludarabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Many patients with brain tumor respond to treatment, but then the tumor starts to grow again. Giving chemotherapy in combination with cellular immunotherapy may kill more tumor cells and improve the outcome of treatment. Read Less

The overarching objective of this study is to use novel precision medicine strategies based on inherited and acquired leukemia-specific genomic features and targeted treatment approaches to improve the cure rate and quality of life of children with acute lymphoblastic leukemia (ALL) and acute lymphoblastic lymphoma (LLy). Primary Therapeutic Objectives: * To improve the event-free survival of provisional standard- or high-risk patients with genetically or immunologically targetable lesions or minimal residual disease (MRD) ≥ 5% at Day 15 or Day 22 or ≥1% at the end of Remission Induction, by the addition of molecular and immunotherapeutic approaches including tyrosine kinase inhibitors or chimeric antigen receptor (CAR) T cell / blinatumomab for refractory B-acute lymphoblastic leukemia (B-ALL) or B-lymphoblastic lymphoma (B-LLy), and the proteasome inhibitor bortezomib for those lacking targetable lesions. * To improve overall treatment outcome of T acute lymphoblastic leukemia (T-ALL) and T-lymphoblastic lymphoma (T-LLy) by optimizing pegaspargase and cyclophosphamide treatment and by the addition of new agents in patients with targetable genomic abnormalities (e.g., activated tyrosine kinases or JAK/STAT mutations) or by the addition of bortezomib for those who have a poor early response to treatment but no targetable lesions, and by administering nelarabine to T-ALL and T-LLy patients with leukemia/lymphoma cells in cerebrospinal fluid at diagnosis or MRD ≥0.01% at the end of induction. * To determine in a randomized study design whether the incidence and/or severity of acute vincristine-induced peripheral neuropathy can be reduced by decreasing the dosage of vincristine in patients with the high-risk CEP72 TT genotype or by shortening the duration of vincristine therapy in standard/high-risk patients with the CEP72 CC or CT genotype. Secondary Therapeutic Objectives: * To estimate the event-free survival and overall survival of children with ALL and to assess the non-inferiority of TOTXVII compared to the historical control given by TOTXVI. * To estimate the event-free survival and overall survival of children with LLy when ALL diagnostic and treatment approaches are used. * To evaluate the efficacy of blinatumomab in B-ALL patients with end of induction MRD ≥0.01% to \<1% and those (regardless of MRD level or TOTXVII risk category) with the genetic subtypes of BCR-ABL1, ABL-class fusion, JAK-STAT activating mutation, hypodiploid, iAMP21, ETV6-RUNX1-like, MEF2D, TCF3-HLF, or BCL2/MYC or with Down syndrome, by comparing event-free survival to historical control from TOTXVI. * To determine the tolerability of combination therapy with ruxolitinib and Early Intensification therapy in patients with activation of JAK-STAT signaling that can be inhibited by ruxolitinib and Day 15 or Day 22 MRD ≥5%, Day 42 MRD ≥1%, or LLy patients without complete response at the End of Induction and all patients with early T cell precursor leukemia. Biological Objectives: * To use data from clinical genomic sequencing of diagnosis, germline/remission and MRD samples to guide therapy, including incorporation of targeted agents and institution of genetic counseling and cancer surveillance. * To evaluate and implement deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) sequencing-based methods to monitor levels of MRD in bone marrow, blood, and cerebrospinal fluid. * To assess clonal diversity and evolution of pre-leukemic and leukemic populations using DNA variant detection and single-cell genomic analyses in a non-clinical, research setting. * To identify germline or somatic genomic variants associated with drug resistance of ALL cells to conventional and newer targeted anti-leukemic agents in a non-clinical, research setting. * To compare drug sensitivity of ALL cells from diagnosis to relapse in vitro and in vivo and determine if acquired resistance to specific agents is related to specific somatic genome variants that are not detected or found in only a minor clone at initial diagnosis. Supportive Care Objectives * To conduct serial neurocognitive monitoring of patients to investigate the neurocognitive trajectory, mechanisms, and risk factors. * To evaluate the impact of low-magnitude high frequency mechanical stimulation on bone mineral density and markers of bone turnover. There are several Exploratory Objectives. Read Less

This phase I trial studies the side effects and best dose of CS1-chimeric antigen receptor (CAR) T therapy after chemotherapy in treating patients who have CS1 positive multiple myeloma that has come back (relapsed) or does not respond to treatment (refractory). Immune cells can be engineered to kill multiple myeloma cells by inserting a piece of deoxyribonucleic acid (DNA) into the immune cells using a lentiviral vector such as CS1, that allows them to recognize multiple myeloma cells. These engineered immune cells, CS1-CAR T cells, may kill multiple myeloma cells. Read Less
