  • Safety and Effectiveness of Granulocyte Transfusions in Resolving Infection in People With Neutropenia (The RING Study)
  • Neutropenia, a condition characterized by an abnormally low number of infection-fighting white blood cells called neutrophils, commonly develops in people who have undergone chemotherapy or hematopoietic stem cell (HSC) transplantation. The severely reduced immunity of those with neutropenia can put them at risk of entry of life-threatening infections, making the implementation of treatments that increase white blood cell numbers important. Several studies have shown that the transfusion of donor granulocytes, a type of white blood cell that includes neutrophils, is effective in promoting the recovery of adequate numbers of granulocytes. However, granulocyte transfusions can cause side effects, and it is not known whether the success of the therapy outweighs the health risks of the side effects. This study will evaluate the safety and effectiveness of granulocyte transfusions in treating people with a bacterial or fungal infection during neutropenia.

  • Transcranial Doppler (TCD) With Transfusions Changing to Hydroxyurea
  • The primary goal of the Phase III TWiTCH trial is to compare 24 months of alternative therapy (hydroxyurea) to standard therapy (transfusions) for pediatric subjects with sickle cell anemia and abnormally high (≥200 cm/sec) Transcranial Doppler (TCD) velocities, who currently receive chronic transfusions to reduce the risk of primary stroke. For the alternative treatment regimen (hydroxyurea) to be declared non-inferior to the standard treatment regimen (transfusions), after adjusting for baseline differences, the hydroxyurea-treated group must have a mean TCD velocity similar to that observed with transfusion prophylaxis.

  • 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.

  • Safety and Efficacy Trial of Danazol in Patients With Fanconi Anemia or Dyskeratosis Congenita
  • Fanconi anemia (FA) and Dyskeratosis congenita (DC) are inherited bone marrow failure syndromes. The current androgen treatments (e.g., oxymetholone) used to treat FA and DC can cause unwanted masculinizing side effects, indicating a need for a different medication. Danazol is a less potent androgen,and may therefore have fewer masculinizing side effects. Danazol is currently approved by the Food and Drug Administration (FDA) for the treatment of other diseases, but it has never been studied in patients with FA and DC. The main purpose of this study is to see if danazol is a safe treatment for FA and DC. Specifically,we would like to determine: - the best dose of danazol; - how fast hemoglobin (a protein that carries oxygen in the blood) levels rise in FA and DC patients receiving danazol therapy; and - the genetic pattern (known as expression profile) of certain cells in response to danazol, which can predict how well people respond to the medication. Subjects who enroll in the study will be treated with danazol for up to 24 weeks (about 6 months), and will have up to 11 study visits, including followup visits at 38 weeks (9 months) and 52 weeks (one year).

  • Pilot and Feasibility Study of Hematopoietic Stem Cell Gene Transfer for the Wiskott-Aldrich Syndrome
  • The Wiskott-Aldrich Syndrome (WAS) is an inherited disorder that results in defects of the blood and bone marrow. It affects boys because the genetic mistake is carried on the X chromosome. Normal people have blood cells called platelets that stop bleeding when blood vessels are damaged. Boys with WAS have low numbers of platelets that do not function correctly. Boys with WAS are thus at risk for severe life-threatening bleeding. A normal immune system is made of special blood cells called white blood cells, which protect against infection and also fight certain types of cancer. In WAS, these white blood cells don't work as well as they should, making these boys very susceptible to infections and to a form of blood cancer known as lymphoma. The abnormal white blood cells of patients with WAS also cause diseases such as eczema and arthritis. Although WAS can be mild, severe forms need treatment as early as possible to prevent life-threatening complications due to bleeding, infection and blood cancer. Over the past decade, investigators have developed new treatments based on the investigators knowledge of the defective gene causing WAS. The investigators can now use genes as a type of medicine that will correct the problem in the patient's own bone marrow. The investigators call this process gene transfer. The procedure is very similar to a normal bone marrow transplant, in that the old marrow is killed off using chemotherapy, but is different because the patient's own bone marrow is given back after it is treated by gene transfer. This approach can be used even if the patient does not have any matched donors available and will avoid problems such as GVHD and rejection. The investigators wish to test whether this approach is safe and whether gene transfer will lead to the development of a healthy immune and blood system.

  • Gene Transfer for Severe Combined Immunodeficiency, X-linked (SCID-X1) Using a Self-inactivating (SIN) Gammaretroviral Vector
  • Researchers are working on ways to treat SCID patients who don't have a matched brother or sister. One of the goals is to avoid the problems that happen with stem cell transplant from parents and unrelated people, such as repeat transplants, incomplete cure of the immune system, exposure to chemotherapy, and graft versus host disease. The idea behind gene transfer is to replace the broken gene by putting a piece of genetic material (DNA) that has the normal gene into the child's cells. Gene transfer can only be done if we know which gene is missing or broken in the patient. For SCID-X1, gene transfer has been done in the laboratory and in two previous clinical trials by inserting the normal gene into stem cells from bone marrow. The bone marrow is the "factory" inside the bones that creates blood and immune cells. So fixing the gene in the bone marrow stem cells should fix the immune problem, without giving chemotherapy and without risk of graft versus host disease, because the child's own cells are used, rather than another person's. Out of the 20 subjects enrolled in the two previous trials, 18 are alive with better immune systems after gene transfer. Two of the surviving subjects received gene corrected cells over 10 years ago. Gene transfer is still research for two reasons. One is that not enough children have been studied to tell if the procedure is consistently successful. Of the 20 children enrolled in the previous two trials, one child did not have correction of the immune system, and died of complications after undergoing stem cell transplant. The second important reason why gene transfer is research is that we are still learning about the side effects of gene transfer and how to do gene transfer safely. In the last two trials, 5 children have experienced a serious side effect. These children developed leukemia related to the gene transfer itself. Leukemia is a cancer of the white blood cells, a condition where a few white blood cells grow out of control. Of these children, 4 of the 5 have received chemotherapy (medication to treat cancer) and are currently in remission (no leukemia can be found by sensitive testing), whereas one died of gene transfer-related leukemia.

  • A Study Of Panobinostat In Children With Refractory Hematologic Malignancies
  • This study is for patients with relapsed or refractory Acute Lymphoblastic Leukemia (ALL), Acute Myelogenous Leukemia (AML), Hodgkin's Disease (HD) or Non-Hodgkin's Lymphoma (NHL). Panobinostat is a new drug that is considered investigational because it has not been approved in the United States by the Food and Drug Administration (FDA), or in any other country. Panobinostat is a histone deacetylase inhibitor (HDACi) and interferes with gene expression found in cells causing them to stop growing or die. Panobinostat has been used in several hundred adults who had leukemia, HD, NHL and other solid tumors. Panobinostat has not been given to children. This is a phase I study. In a phase I study, drugs are tested to the highest dose that can be safely given. Drugs are given at gradually increasing dosages until there are unacceptable side effects. The goal of the Phase I study is to find out the dose of panobinostat that can be safely given to children with relapsed ALL, AML, HD and NHL.

  • Fludarabine-based Conditioning for Severe Aplastic Anemia
  • The purpose of this study is to continue to optimize conditioning regimens in high-risk patients with severe aplastic anemia (SAA) transplanted with marrow from human leukocyte antigen (HLA)-compatible unrelated donors. Specifically, the study will address whether the addition of fludarabine to the conditioning regimen of Deeg et al. will permit reduction in the cyclophosphamide (CY) dose to a point where survival is maintained or improved and sustained hematopoietic engraftment is maintained or improved with reduced major regimen-related toxicity (RRT) and/or early death.

  • Efficacy and Safety Study of Eltrombopag in Pediatric Patients With Thrombocytopenia From Chronic Idiopathic Thrombocytopenic Purpura (ITP)
  • Phase II, multi-center, 3 part, staggered cohort, open-label and double blind, randomized, placebo controlled study involving 3 age-determined cohorts (Cohort 1: between 12 and 17 years old; Cohort 2: between 6 and 11 years old; Cohort 3: between 1 and 5 years old). Daily dosing with eltrombopag will begin with 5 patients in the oldest age cohort in an open label fashion, and a review of safety, pharmacokinetic and platelet count data will be performed regularly. If no safety concerns are identified after 12 weeks, 18 additional patients will be randomised to placebo or eltrombopag (2:1 randomisation). After 7 weeks of randomized treatment, all patients will receive eltrombopag in an open label fashion. The total duration of treatment with eltrombopag will be 24 weeks. If at the time of the aforementioned 12 week review of the first 5 patients no safety issues are identified, dosing will begin in the next lower age cohort with an initial group of 5 patients. The same procedure will be followed in terms of safety review and subsequent enrolment and randomisation of the additional patients. Initiation of the younger age cohort will take place once data from the previous has been evaluated. Doses will be adjusted according to platelet counts and tolerability. The study will include a review of the safety data by a Data Safety Monitoring Board.
