Sickle Cell Disease and the Genomic and Gene Therapy Needs of Stakeholders
The primary objectives of this prospective mixed-method interview study are to use semi-structured interviews in parents of sickle cell disease (SCD) patients to describe parental attitudes of research involving genomic sequencing, including concerns about participation and expectations from researchers and second, to use surveys to quantitatively measure genetic/genomic knowledge, trust in health care provider, and literacy/numeracy ability in parents of children with SCD and adolescents with SCD. Secondary objectives are development of a web-based tool about treatment options for SCD that fosters patient-clinician communication and promotes shared decision-making. The web-based tool will undergo usability and pilot testing to ensure it is accessible to families and provide data about strategies for integrating into clinical conversations about treatment options. Investigators will use the data generated to reduce the risk of misunderstanding about DNA and genetic research and build strong relationships between SCD families and researchers in the future. The project will design educational information and study materials to help parents of children with SCD understand important details about genomic medicine in SCD care.

Hematopoietic Stem Cell BCL11A Enhancer Gene Editing for Severe β-Hemoglobinopathies
A promising approach for the treatment of genetic diseases is called gene therapy. Gene therapy is a relatively new field of medicine that uses genetic material (mostly DNA) from the patient to treat his or her own disease. In gene therapy, the investigators introduce new genetic material in order to fix or replace a diseased gene, with the goal of curing the disease. The procedure is similar to a bone marrow transplant, in that the patient's malfunctioning blood stem cells are reduced or eliminated using chemotherapy, but it is different because instead of using a different person's (donor) blood stem cells for the transplant, the patient's own blood stem cells are given back after the new genetic material has been introduced into those cells. This approach has the advantage of eliminating any risk of Graft-Versus-Host Disease (GVHD), reducing the risk of graft rejection, and may also allow less chemotherapy to be utilized for the conditioning portion of the transplant procedure. The method used to fix or replace a diseased gene is called gene editing. A person's own cells are edited using a specialized biological medicine that has been formulated for use in human beings. Fetal hemoglobin (HbF) is a healthy, non-sickling kind of hemoglobin. Investigators have recently discovered a gene called BCL11A that is very important in the control of fetal hemoglobin expression. Increasing the expression of this gene in sickle cell patients could increase the amount of fetal hemoglobin while simultaneously reducing the amount of sickle hemoglobin in their blood, and therefore potentially cure the condition.

Gene Transfer for Sickle Cell Disease
A promising approach for the treatment of genetic diseases is called gene therapy. Gene therapy is a relatively new field of medicine that uses genetic material (mostly DNA) from the patient to treat his or her own disease. In gene therapy, the investigators introduce new genetic material in order to fix or replace the patient's disease gene, with the goal of curing the disease.

This approach has the advantage of eliminating any risk of GVHD, reducing the risk of graft rejection, and may also allow less chemotherapy to be utilized for the conditioning portion of the transplant procedure. The method used to introduce the gene into the patient's own blood stem cells is to engineer and use a modified version of a virus (called a 'vector') that efficiently inserts the "correcting" genetic material into the cells. The vector is a specialized biological medicine that has been formulated for use in human beings. The investigators have recently discovered a gene that is very important in the control of fetal hemoglobin expression. Increasing the expression of this gene in sickle cell patients could increase the amount of fetal hemoglobin while simultaneously reducing the amount of sickle hemoglobin in their blood, and therefore potentially cure the condition. In summary, the advantages of a gene therapy approach include: 1) it can be used even if the patient does not have a matched donor available; 2) it may allow a reduction in the amount of chemotherapy required to prepare the patient for the transplant; and 3) it will avoid the strong medicines often required to prevent and treat GVHD and rejection. The goal is to test whether this approach is safe, and whether using gene therapy to change the expression of this particular gene will lead to increased fetal hemoglobin production in people with sickle cell disease.

A Gene Transfer Study Inducing Fetal Hemoglobin in Sickle Cell Disease (GRASP, BMT CTN 2001)
A promising approach for the treatment of genetic diseases is called gene therapy. Gene therapy is a relatively new field of medicine in which genetic material (mostly DNA) in the patient is changed to treat his or her own disease. In gene therapy, we introduce new genetic material in order to fix or replace the patient's disease gene, with the goal of curing the disease. The procedure is similar to a bone marrow transplant, in that the patient's malfunctioning blood stem cells are reduced or eliminated using chemotherapy, but it is different because instead of using a different person's (donor) blood stem cells for the transplant, the patient's own blood stem cells are given back after the new genetic material has been introduced into those cells. This approach has the advantage of eliminating any risk of graft versus host disease (GVHD), reducing the risk of graft rejection, and may also allow less chemotherapy to be utilized for the conditioning portion of the transplant procedure. To introduce new genetic material into the patient's own blood stem cells we use a modified version of a virus (called a 'vector') that efficiently inserts the "correcting" genetic material into the cells. The vector is a specialized biological medicine that has been formulated for use in human beings. Fetal hemoglobin (HbF) is a healthy, non-sickling kind of hemoglobin. The investigators have discovered a gene that is very important in controlling the amount of HbF. Decreasing the expression of this gene in sickle cell patients could increase the amount of fetal hemoglobin while simultaneously reducing the amount of sickle hemoglobin in their blood, specifically the amount in red blood cells where sickle hemoglobin causes damage to the cell, and therefore potentially cure or significantly improve the condition. The gene we are targeting for change in this study that controls the level of fetal hemoglobin is called BCL11A. In summary, the advantages of a gene therapy approach include: 1) it can be used even if the patient does not have a matched donor available; 2) it may allow a reduction in the amount of chemotherapy required to prepare the patient for the transplant; and 3) it will avoid certain strong medicines often required to prevent and treat GVHD and rejection. Our lab studies with normal mice, mice that have a form of SCD, and with cells from the bone marrow of SCD patients who have donated bone marrow for research purposes show this approach is very effective in reducing the amount of sickle hemoglobin in red cells. Our pilot trial testing this approach in 10 patients with SCD has shown that the treatment has not caused any unexpected safety problems, and that it increases HbF within the red blood cells. Our goal is to continue to test whether this approach is safe, and whether using gene therapy to change the expression of BCL11A will lead to decreased episodes of vaso-occlusive crisis pain in people with SCD.

This process is intended to boost fetal hemoglobin (HbF), which can substitute for reduced or absent adult (defective) hemoglobin. 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.

Evaluating the Safety and Effectiveness of Mozobil Mobilization in Adults With Beta-Thalassemia Major
Thalassemia is considered the most common genetic disorder worldwide, occurring with high frequency in Mediterranean areas, the Middle East, Southeast Asia, and the Pacific Islands. Currently, the only cure for thalassemia is bone marrow transplantation from a related, compatible donor. Gene transfer, achieved by transplantation of the patient's own blood stem cells that have been genetically-modified with the corrected gene, could potentially cure thalassemia. The first step in developing gene transfer for treatment of thalassemia is to develop a safe and effective method to obtain blood stem cells from thalassemia patients. Eventually, high numbers of genetically modified cells will need to be infused into the patient for clinical gene transfer to be effective. The blood stem cells are obtained by giving a "mobilization" agent to the patients. This causes the stem cells to leave the bone marrow and go into the blood. The purpose of this study is to test the safety and effectiveness of the new mobilization agent, Mozobil, in causing mobilization of blood stem cells for patients with beta-thalassemia major.
Evaluating the Safety of G-CSF Mobilization in Individuals With Beta Thalassemia Major
Beta thalassemia major is a serious genetic disease of the blood. Treatments are limited, and although a bone marrow transplant from a compatible donor can be curative, only a limited percentage of individuals with this disease have a matched donor available. A long-term goal of study researchers is to develop a gene transfer process as a method of curing beta thalassemia major. Gene transfer involves obtaining blood stem cells from an individual, adding a normal globin gene to the stem cells, and putting the cells back into the individual. Before gene transfer methods can be attempted in individuals with beta thalassemia major, a safe method of obtaining blood stem cells needs to be developed. The purpose of this study is to investigate the safety and feasibility of collecting peripheral blood stem cells (PBSC) from individuals with beta thalassemia major. Research participants will be given G-CSF (filgrastim) for several days to increase the number of stem cells in the blood, a process called "mobilization." After mobilization, participants will undergo a procedure called apheresis to remove the white blood cells. Researchers in the laboratory will purify the stem cells from the mixture and test methods of putting a normal globin gene into the stem cells. Half of the participants will receive hydroxyurea (HU) prior to G-CSF mobilization. HU is used in splenectomized patients to attempt to reduce the risk of clotting during mobilization. In non-splenectomized patients, HU is given in an attempt to decrease the size of the spleen.
