  • Standard-Dose Combination Chemotherapy or High-Dose Combination Chemotherapy and Stem Cell Transplant in Treating Patients With Relapsed or Refractory Germ Cell Tumors
  • This randomized phase III trial studies how well standard-dose combination chemotherapy works compared to high-dose combination chemotherapy and stem cell transplant in treating patients with germ cell tumors that have returned after a period of improvement or did not respond to treatment. Drugs used in chemotherapy, such as paclitaxel, ifosfamide, cisplatin, carboplatin, and etoposide, 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. Giving chemotherapy before a stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. Giving colony-stimulating factors, such as filgrastim or pegfilgrastim, and certain chemotherapy drugs, helps stem cells move from the bone marrow to the blood so they can be collected and stored. Chemotherapy is then given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy. It is not yet known whether high-dose combination chemotherapy and stem cell transplant are more effective than standard-dose combination chemotherapy in treating patients with refractory or relapsed germ cell tumors.

  • Gut Decontamination In Pediatric Allogeneic Hematopoietic
  • This research study is for participants who are undergoing allogeneic hematopoietic stem cell transplantation (HSCT) and are at risk for developing acute graft-versus-host disease (GVHD). GVHD is a complication of HSCT in which immune cells from the donor cause inflammation and injury to tissues and organs of the HSCT recipient. Vancomycin-polymyxin B (commonly called "vancopoly") is an oral antibiotic that is given to people undergoing allogeneic HSCT as a preventive measure for acute GVHD. This research study is studying the effects of vancopoly on the microorganisms living in the intestine during and after stem cell transplantation.

  • Radiation- and Alkylator-free Bone Marrow Transplantation Regimen for Patients With Dyskeratosis Congenita
  • Dyskeratosis congenita is a disease that affects numerous parts of the body, most typically causing failure of the blood system. Lung disease and a predisposition to cancer are also frequent causes of illness and death. Bone marrow transplantation (BMT) can cure the blood system but can make the lung disease and cancer predisposition worse, because of agents such as alkylators and radiation that are typically used in the procedure. Based on the biology of DC, we hypothesize that it may be possible to avoid these agents in patients with DC, and still have a successful BMT. In this protocol we will test whether a regimen that avoids alkylators and radiation can permit successful BMT without compromising survival in patients with DC.

  • Nivolumab With or Without Ipilimumab in Treating Younger Patients With Recurrent or Refractory Solid Tumors or Sarcomas
  • This phase I/II trial studies the side effects and best dose of nivolumab when given with or without ipilimumab to see how well they work in treating younger patients with solid tumors or sarcomas that have come back (recurrent) or do not respond to treatment (refractory). Monoclonal antibodies, such as nivolumab and ipilimumab, may block tumor growth in different ways by targeting certain cells. It is not yet known whether nivolumab works better alone or with ipilimumab in treating patients with recurrent or refractory solid tumors or sarcomas.

  • Study of Gene Therapy Using a Lentiviral Vector to Treat X-linked Chronic Granulomatous Disease
  • Chronic Granulomatous Disease (CGD) is an inherited immunodeficiency disorder which results from defects that prevent white blood cells from effectively killing bacteria, fungi and other microorganisms. Chronic granulomatous inflammation may compromise vital organs and account for additional morbidity. CGD is thought to affect approximately 1 in 200,000 persons, although the real incidence might be higher due to under-diagnosis of milder phenotypes. The first gene therapy approaches in X-CGD have shown that effective gene therapy requires bone-marrow (BM) conditioning with chemotherapy to make space for the gene-modified cells to engraft. These studies demonstrated that transplantation of gene modified stem cells led to production of white blood cells that could clear existing infections. However, some trails using mouse-derived retroviral vectors were complicated by the development of myelodysplasia and leukemia-like growth of blood cells. This trial will evaluate a new lentiviral vector that may be able to correct the defect, but have much lower risk for the complication. This study is a prospective non-controlled, non-randomized Phase I/II clinical trial to assess the safety, feasibility and efficacy of cellular gene therapy in patients with chronic granulomatous disease using transplantation of autologous bone marrow CD34+ cells transduced ex vivo by the G1XCGD lentiviral vector containing the human CGD gene. Primary objectives include evaluation of safety and evaluation of efficacy by biochemical and functional reconstitution in progeny of engrafted cells and stability at 12 months. Secondary objectives include evaluation of clinical efficacy, longitudinal evaluation of clinical effect in terms of augmented immunity against bacterial and fungal infection, transduction of CD34+ hematopoietic cells from X-CGD patients by ex vivo lentivirus-mediated gene transfer, and evaluation of engraftment kinetics and stability. Approximately 3-5 patients will be treated per site with a goal of 10 total patients to be treated with G1XCGD lentiviral vector.

  • Sorafenib and Cyclophosphamide/Topotecan in Patients With Relapsed and Refractory Neuroblastoma
  • This study will combine three drugs: sorafenib, cyclophosphamide and topotecan. Adding sorafenib to cyclophosphamide and topotecan may increase the effectiveness of this combination. The investigators first need to find out the highest dose of sorafenib that can be given safely together with cyclophosphamide and topotecan. This is the first study to test giving these three drugs together and will help determine the highest dose of sorafenib that can safely be given together with cyclophosphamide and topotecan to patients with resistant/relapsed neuroblastoma.

  • Matched Targeted Therapy For High-Risk Leukemias
  • This research study is seeking to gain new knowledge about recurrent, refractory, or high risk leukemias and myelodysplastic syndrome in children and young adults. It is evaluating the use of specialized testing which analyzes the DNA and RNA of leukemia cells, called leukemia profiling. Once profiling is performed, the results are evaluated by an expert panel of physicians and scientists to determine if there is a targeted drug available that could attack the identified leukemia-associated alteration. This matched targeted therapy (MTT) recommendation is then communicated to the participant's primary oncologist.

  • MIBG With Dinutuximab
  • 131I-Metaiodobenzylguanidine (131I-MIBG) is one of the most effective therapies utilized for neuroblastoma patients with refractory or relapsed disease. In this pediatric phase 1 trial, 131I-MIBG will be given in combination with dinutuximab, a chimeric 14.18 monoclonal antibody. This study will utilize a traditional Phase I dose escalation 3+3 design to determine a recommended phase 2 pediatric dose. An expansion cohort of an additional 6 patients may then be enrolled.

  • Carfilzomib in Combination With Cyclophosphamide and Etoposide for Children
  • This study evaluates the use of carfilzomib in combination with cyclophosphamide and etoposide for children with relapsed/refractory solid tumors or leukemia. The medications cyclophosphamide and etoposide are standard drugs often used together for the treatment of cancer in children with solid tumors or leukemia. Carfilzomib is FDA (Food and Drug Administration) approved in the United States for adults with multiple myeloma (a type of cancer). However, this drug is not approved for the disease being treated in this study. Since carfilzomib has not yet been used in this setting to treat this condition, the investigators must first find the best dose to give. The investigators are looking for the highest dose of carfilzomib that can be given safely. Therefore, not all children taking part in this study will receive the same dose of the study drug in the first part of the trial.

  • Phase I/II Trial of Lentiviral Gene Transfer for SCID-X1 With Low Dose Targeted Busulfan Conditioning
  • This is a phase I/II open label multi-center study in which patients will receive low dose targeted busulfan followed by infusion of autologous CD34+ selected bone marrow or mobilized peripheral blood cells transduced with the G2SCID vector. Subjects will be enrolled over 3 years and be followed for 2 years post-infusion on this protocol, then followed long-term on a separate long-term follow-up protocol. Enrollment of subjects will be agreed upon by representatives of both sites. Data will be collected uniformly from both sites through an electronic capture system and key laboratory studies will be centralized. Harvest, cellular manufacturing and infusion will occur at each site using the same SOPs. Key aspects of cellular product characterization will be centralized

  • Dinutuximab, Sargramostim, and Combination Chemotherapy in Treating Patients With Newly Diagnosed High-Risk Neuroblastoma Undergoing Stem Cell Transplant
  • This phase II trial studies the side effects and how well dinutuximab and sargramostim work with combination chemotherapy in patients with high-risk neuroblastoma undergoing stem cell transplant. Immunotherapy with monoclonal antibodies, such as dinutuximab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Sargramostim helps the body produce normal infection-fighting white blood cells. Giving chemotherapy before a stem cell transplant, with drugs such as cisplatin, etoposide, vincristine, doxorubicin, cyclophosphamide, thiotepa, melphalan, etoposide, carboplatin, topotecan, and isotretinoin, helps kill any cancer cells that are in the body and helps make room in a patient's bone marrow for new blood-forming cells (stem cells). Giving dinutuximab and sargramostim with combination chemotherapy may work better in treating patients with high-risk neuroblastoma undergoing stem cell transplant.

  • A Phase II Dose-escalation Study Characterizing the PK of Eltrombopag in Pediatric Patients With Previously Untreated or Relapsed Severe Aplastic Anemia or Recurrent Aplastic Anemia
  • This is a phase II, open label, multi-center, intra-patient dose escalation study to characterize the pharmacokinetics after oral administration of eltrombopag in combination with immunosuppressive therapy in pediatric patients with previously untreated or relapsed/refractory severe aplastic anemia or recurrent aplastic anemia. All patients will be treated with eltrombopag for the 26-week Treatment Period, followed by a 52-week Follow-Up Period. Patients who have been previously untreated with immunosuppressive therapy will be treated according to the standard of care, hATG/cyclosporine, in addition to eltrombopag. Patients with relapsed/refractory SAA or recurrent AA will be enrolled into one of two treatment options: hATG/cyclosporine plus eltrombopag or cyclosporine plus eltrombopag, depending on prior treatment with immunosuppressive therapy. After initiating treatment with eltrombopag, patients will have their dose assessed and modified as tolerated, until the targeted platelet count or maximum dose is achieved. Pharmacokinetic assessments will be performed at time points intended to capture steady state PK of the starting dose and highest dose achieved. Upon completion of the Treatment and Follow-Up Periods, all patients will be offered the opportunity to enroll in an additional 3 year Long Term Follow-Up Period.

  • Study to Investigate Safety, Pharmacokinetic (PK), Pharmacodynamic (PD) and Clinical Activity of Trametinib in Subjects With Cancer or Plexiform Neurofibromas and Trametinib in Combination With Dabrafenib in Subjects With Cancers Harboring V600 Mutations
  • This is a 3-part (Part A, Part B, Part C), Phase I/IIa, multi-center, open label, study in pediatric subjects with refractory or recurrent tumors. Part A is a repeat dose, dose escalation monotherapy study that will identify the recommended phase II dose (RP2D) on the continuous dosing schedule using a 3 + 3 dose-escalation procedure. Part B will evaluate the preliminary activity of trametinib monotherapy in 4 disease-specific cohorts of subjects. Each cohort will enroll at least 10 response-evaluable subjects (evaluable for response is defined as a subject with a pre-dose and at least 1 post-dose disease assessment or clinical assessment of progression of disease). Part C is will be a 3+3 study design to determine the safety, tolerability and preliminary activity of the RP2D of trametinib in combination with a limited dose escalation of dabrafenib. Part C will enroll up to 18 subjects. . The overall goal of this trial is to efficiently establish safe, pharmacologically relevant dose of trametinib in infants, children and adolescents and determine preliminary activity of trametinib monotherapy in selected recurrent, refractory or unresectable childhood tumors.

  • A Pilot, Phase I/II Study of the Amino Acid Leucine in the Treatment of Patients With Transfusion-Dependent Diamond Blackfan Anemia
  • This study will determine the safety and possibility of giving the amino acid, leucine, in patients with Diamond Blackfan anemia(DBA)who are on dependent on red blood cell transfusions. The leucine is expected to produce a response in patients with DBA to the point where red blood cell production is increased. Red cell transfusions can then be less frequent or possibly discontinued. The investigators will study the side effects, if any, of giving leucine to DBA patients. Leucine levels of leucine will be obtained at baseline and during the study. The drug leucine will be provided in capsule form and taken 3 times a day for a total of 9 months.

  • Study of Lorlatinib (PF-06463922)
  • Lorlatinib is a novel inhibitor across ALK variants, including those resistant to crizotinib. In this first pediatric phase 1 trial of lorlatinib, the drug will be utilized as a single agent and in combination with chemotherapy in patients with relapsed/refractory neuroblastoma. The dose escalation phase of this study (Cohort A1) uses a traditional Phase I 3+3 design. Once a recommended phase 2 pediatric dose is identified, an expansion cohort of 6 patients (Cohort B1), within which ALKi naïve patients will be prioritized, will be initiated. Parallel cohorts will be initiated in adults or patients with large BSA (Cohort A2) and in combination with chemotherapy upon establishing RP2D (Cohort B2).

  • A Study to Assess the Safety, Tolerability, and Efficacy of ST-400 for Treatment of Transfusion-Dependent Beta-thalassemia (TDT)
  • This is a single-arm, multi-site, single-dose, Phase 1/2 study to assess ST-400 in 6 subjects with transfusion-dependent β-thalassemia (TDT) who are ≥18 and ≤40 years of age. ST-400 is a type of investigational therapy that consists of gene edited cells. ST-400 is composed of the patient's own blood stem cells which are genetically modified in the laboratory using Sangamo's zinc finger nuclease (ZFN) technology to disrupt a precise and specific sequence of the enhancer of the BCL11A gene (which normally suppresses fetal hemoglobin production in erythrocytes). This process is intended to boost fetal hemoglobin (HbF), which can substitute for reduced or absent adult (defective) hemoglobin, and is done without the use of integrating viral vectors. ST-400 is then infused back into the patient after receiving conditioning chemotherapy to make room for the new cells in the bone marrow, with the aim of producing new erythrocytes with increased amounts of HbF. The primary objective is to understand safety and tolerability of ST-400, and secondary objectives are to assess the effects on HbF levels and transfusion requirements.
