Cord Blood Transplant, Cyclophosphamide, Fludarabine, and Total-Body Irradiation in Treating Patients With High-Risk Hematologic Diseases
Description

This phase II trial studies how well giving an umbilical cord blood transplant together with cyclophosphamide, fludarabine, and total-body irradiation (TBI) works in treating patients with hematologic diseases. Giving chemotherapy, such as cyclophosphamide, fludarabine and thiotepa, and TBI before a donor cord blood transplant (CBT) helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after transplant may stop this from happening in patients with high-risk hematologic diseases.

Study of a Geriatric Assessment to Plan a Treatment Approach for Older People With Various Blood Disorders
Description

This study will evaluate whether a geriatric assessment can lead to better treatment outcomes in older patients (age 60+) with a myeloid malignancy including acute myeloid leukemia, ,myelodysplastic syndromes, myeloproliferative neoplasms, or related blood disorders who are going to receive chemotherapy or another treatment to prepare the body for an allogeneic hematopoietic stem cell transplant (allo-HCT). The geriatric assessment includes looking at patients' cognitive function (thinking processes), physical function, mobility (ability to move the body), mood, nutrition, and current medications to help decide the type of treatment they'll receive. Another purpose of this study is to see whether use of the geriatric assessment improves participants' quality of life. We will evaluate participants' quality of life through questionnaires.

HPV Vaccine Hesitancy Among Indiana Youth With Cancer and Blood Diseases
Description

For the identified groups of patients (survivors of childhood cancer and youth with sickle cell disease) the investigators want to better understand the barriers to, and facilitators of, HPV vaccination. Through HCP interviews the investigators will also assess both attitudinal and logistical obstacles to HPV vaccination. Some subspecialty HCPs may believe, for instance, that it is the primary care provider's responsibility to vaccinate or they may be unfamiliar with the requirement to enter vaccination data into CHIRP. Also, in some cases HPV vaccine may not be readily available in subspecialty clinic locations and/or subspecialty HCPs may not be Vaccines for Children (VFC) providers. Participants: the investigators will focus on two patient groups: survivors of childhood cancer, which includes children aged 9-21 years who have completed active therapy for cancer and are eligible for vaccination, and sickle cell disease, which includes children aged 9-21 years with a diagnosis of sickle cell disease. The investigators will recruit parents of children aged 9-21 years and older adolescents aged 18-21 years. For pediatric patients, the investigators selected a lower age of 9 years because HPV vaccine is licensed down to 9 years of age, and an upper limit of 21 years, as that is considered the upper bound of adolescence by the American Academy of Pediatrics. For patients 9-17 years of age, only parents will be interviewed by video or phone because parents are the vaccine decision-makers. For patients 18-21 years of age, the investigators will interview both young adults and their parents, because, while the young adult has legal decision-making capacity, in reality, the decision is frequently made jointly by the young adult and parent, and older adolescents are frequently unwilling to go against their parents' wishes. All research procedures will be conducted in English. Participants will be excluded if they have an intellectual disability or severe medical illness such that they are unable to consent or to understand the questions.

Identifying Best Approach in Improving Quality of Life and Survival After a Donor Stem Cell Transplant in Older, Medically Infirm, or Frail Patients With Blood Diseases
Description

This phase II/III trial studies the best approach in improving quality of life and survival after a donor stem cell transplant in older, weak, or frail patients with blood diseases. Patients who have undergone a transplant often experience increases in disease and death. One approach, supportive and palliative care (SPC), focuses on relieving symptoms of stress from serious illness and care through physical, cultural, psychological, social, spiritual, and ethical aspects. While a second approach, clinical management of comorbidities (CMC) focuses on managing multiple diseases, other than cancer, such as heart or lung diseases through physical exercise, strength training, stress reduction, medication management, dietary recommendations, and education. Giving SPC, CMC, or a combination of both may work better in improving quality of life and survival after a donor stem cell transplant compared to standard of care in patients with blood diseases.

TERMINATED
Use of T-allo10 in Hematopoietic Stem Cell Transplantation (HSCT) for Blood Disorders
Description

A significant number of patients with hematologic malignancies need a hematopoietic stem cell transplant (HSCT) to be cured. Only about 50% of these patients have a fully matched donor, the remaining patients will require an HSCT from a mismatched related or unrelated donor. Almost 60% of these mismatched donor HSCTs will result in graft-versus-host disease (GvHD), which can cause significant morbidity and increased non-relapse mortality. GvHD is caused by the donor effector T cells present in the HSC graft that recognize and react against the mismatched patient's tissues. Researchers and physicians at Lucile Packard Children's Hospital, Stanford are working to prevent GvHD after HSCT with a new clinical trial. The objective of this clinical program is to develop a cell therapy to prevent GvHD and induce graft tolerance in patients receiving mismatched unmanipulated donor HSCT. The cell therapy consists of a cell preparation from the same donor of the HSCT (T-allo10) containing T regulatory type 1 (Tr1) cells able to suppress allogenic (host-specific) responses, thus decreasing the incidence of GvHD. This is the first trial of its kind in pediatric patients and is only available at Lucile Packard Children's Hospital, Stanford. The purpose of this phase 1 study is to determine the safety and tolerability of a cell therapy, T-allo10, to prevent GvHD in patients receiving mismatched related or mismatched unrelated unmanipulated donor HSCT for hematologic malignancies.

Investigation of the Genetics of Hematologic Diseases
Description

The purpose of this study is to collect and store samples and health information for current and future research to learn more about the causes and treatment of blood diseases. This is not a therapeutic or diagnostic protocol for clinical purposes. Blood, bone marrow, hair follicles, nail clippings, urine, saliva and buccal swabs, left over tissue, as well as health information will be used to study and learn about blood diseases by using genetic and/or genomic research. In general, genetic research studies specific genes of an individual; genomic research studies the complete genetic makeup of an individual. It is not known why many people have blood diseases, because not all genes causing these diseases have been found. It is also not known why some people with the same disease are sicker than others, but this may be related to their genes. By studying the genomes in individuals with blood diseases and their family members, the investigators hope to learn more about how diseases develop and respond to treatment which may provide new and better ways to diagnose and treat blood diseases. Primary Objective: * Establish a repository of DNA and cryopreserved blood cells with linked clinical information from individuals with non-malignant blood diseases and biologically-related family members, in conjunction with the existing St. Jude biorepository, to conduct genomic and functional studies to facilitate secondary objectives. Secondary Objectives: * Utilize next generation genomic sequencing technologies to Identify novel genetic alternations that associate with disease status in individuals with unexplained non-malignant blood diseases. * Use genomic approaches to identify modifier genes in individuals with defined monogenic non-malignant blood diseases. * Use genomic approaches to identify genetic variants associated with treatment outcomes and toxicities for individuals with non-malignant blood disease. * Use single cell genomics, transcriptomics, proteomics and metabolomics to investigate biomarkers for disease progression, sickle cell disease (SCD) pain events and the long-term cellular and molecular effects of hydroxyurea therapy. * Using longitudinal assessment of clinical and genetic, study the long-term outcomes and evolving genetic changes in non-malignant blood diseases. Exploratory Objectives * Determine whether analysis of select patient-derived bone marrow hematopoietic progenitor/stem (HSPC) cells or induced pluripotent stem (iPS) cells can recapitulate genotype-phenotype relationships and provide insight into disease mechanisms. * Determine whether analysis of circulating mature blood cells and their progenitors from selected patients with suspected or proven genetic hematological disorders can recapitulate genotype-phenotype relationships and provide insight into disease mechanisms.

Bone Marrow and Kidney Transplant for Patients With Chronic Kidney Disease and Blood Disorders
Description

The main purpose of this study is to examine the outcome of a combined bone marrow and kidney transplant from a partially matched related (haploidentical or "haplo") donor. This is a pilot study, you are being asked to participate because you have a blood disorder and kidney disease. The aim of the combined transplant is to treat both your underlying blood disorder and kidney disease. We expect to have about 10 people participate in this study. Additionally, because the same person who is donating the kidney will also be donating the bone marrow, there may be a smaller chance of kidney rejection and less need for long-term use of anti-rejection drugs. Traditionally, very strong cancer treatment drugs (chemotherapy) and radiation are used to prepare a subject's body for bone marrow transplant. This is associated with a high risk for serious complications, even in subjects without kidney disease. This therapy can be toxic to the liver, lungs, mucous membranes, and intestines. Additionally, it is believed that standard therapy may be associated with a higher risk of a complication called graft versus host disease (GVHD) where the new donor cells attack the recipient's normal body. Recently, less intense chemotherapy and radiation regimens have been employed (these are called reduced intensity regimens) which cause less injury and GVHD to patients, and thus, have allowed older and less healthy patients to undergo bone marrow transplant. In this study, a reduced intensity regimen of chemotherapy and radiation will be used with the intent of producing fewer toxicities than standard therapy. Typical therapy following a standard kidney transplant includes multiple lifelong medications that aim to prevent the recipient's body from attacking or rejecting the donated kidney. These are called immunosuppressant drugs and they work by "quieting" the recipient's immune system to allow the donated kidney to function properly. One goal in our study is to decrease the duration you will need to be on immunosuppressant drugs following your kidney transplant as the bone marrow transplant will provide you with the donor's immune system which should not attack the donor kidney.

Topical Sodium Nitrite for Chronic Leg Ulcers in Adult Patients With Blood Disorders
Description

Background: - Chronic leg ulcers are a complication of many blood disorders such as sickle cell disease, thalassemia, and other red blood cell disorders. In these disorders, red blood cells break down earlier than normal, which researchers suspect may cause or contribute to the development of leg ulcers; however, the exact cause is unknown, and current therapies are not very effective. Researchers are interested in determining if a research cream made with sodium nitrite, a substance that is known to increase blood flow by dilating blood vessels, may speed up the healing of skin ulcers. Objectives: - To evaluate the safety and effectiveness of topical sodium nitrite cream as a treatment for chronic leg ulcers in individuals with sickle cell disease or other red blood cell disorders. Eligibility: - Individuals at least 18 years of age who have sickle cell disease or another red cell disorder and have had a leg ulcer for more than 4 weeks. Design: * Participants will be screened with a physical examination, medical history, blood tests, and an examination of the ulcer, including x-ray of the leg(s) with the ulcer and swabs from the wound. * Participants will be scheduled for a 5-day inpatient stay at the Clinical Center, with the following procedures: * Days 1 and 2: Participants will have blood draws, a wound assessment, ultrasound of the affected leg, imaging studies (magnetic resonance imaging and infrared photography), thermo-patch application to monitor temperature changes, measurements of blood flow in the skin, and questionnaires about pain and quality of life. An optional skin biopsy may also be conducted with samples taken near the skin ulcer * Day 3: Participants will have one ulcer treated with the topical cream. Frequent blood draws will be conducted before application and then regularly for up to 6 hours after application of the cream. Thirty minutes after the research cream is applied, participants will have imaging studies of the treated leg and measurements of pain levels and blood flow. * Day 4: Participants will have a blood draw and temperature recordings taken. * Day 5: Participants will have the research cream applied and the same imaging studies as before, and will be discharged for care at home. * For the following 3 weeks, participants will come to the clinical center twice a week to have the research cream applied to the leg ulcer and tests performed by the study researchers. * For the fourth and final week, participants will return for additional cream treatment sessions, imaging studies, blood draws, and other tests as directed by the study researchers. * Study participation will end in the following week (week 5). Subjects will come for a final visit one month after the end of the study.

TERMINATED
Pilot Trial of Targeted Immune-Depleting Chemotherapy and Reduced-Intensity Matched Unrelated Double Cord Blood Transplant for the Treatment of Leukemias, Lymphomas, and Pre-Malignant Blood Disorders
Description

Background: * Allogeneic stem cell transplantation (SCT) has been used to treat many kinds of cancer or pre-cancerous conditions that develop in blood or immune system cells. Umbilical cord blood transplantation (UCBT) is a type of allogeneic transplant that is used when none of a patient s siblings are a match and an acceptable match cannot be identified from one of the bone marrow registries. Prior to receiving the cord blood stem cells, large doses of chemotherapy drugs and/or radiation have been traditionally used to eliminate most of the cancerous or abnormal cells from the recipient s system, along with most of his or her own stem cells and immune cells. Donor stem cells then replace the recipient s stem cells in the bone marrow, restoring normal blood production and immunity. In this way, an allogeneic SCT provides not only new blood cells but an entire new immune system. * In the past, allogeneic SCT was performed with very high doses of chemotherapy and/or radiation to get rid of as much of the recipient s cancer as possible and prevent rejection of the treatment. However, intensive chemotherapy or radiation can cause serious side effects, including death. A newer method uses smaller, less toxic doses of chemotherapy and/or radiation before allogeneic SCT. In these reduced-intensity stem cell transplants, the recipient s stem cells and immunity are not completely eliminated, but they are weakened enough to help prevent the donor s cells from being rejected. Objectives: - To study the safety and effectiveness of reduced-intensity stem cell transplants given with immune-depleting chemotherapy and umbilical cord blood provided by an unrelated donor. Eligibility: * Individuals between 18 and 69 years of age who have been diagnosed with any of a number of cancerous and pre-cancerous blood conditions, including lymphoma and leukemia. * Participants must not have a potential donor sibling or a readily available unrelated donor identified through one of the bone marrow donor registries. Design: * Patients will be matched with at least two umbilical cords with an acceptable cell dose. The two frozen umbilical cord blood units will be sent to the NIH prior to the date of transplant. * Patients will receive one, two, or three cycles of chemotherapy (based on the type of disease) to treat the disease and to weaken the immune system. Patients who already have a weakened immune system from other treatments will not receive this round of chemotherapy. * Patients will then receive 4 days of reduced-intensity transplant chemotherapy (also called the conditioning regimen ) to prepare for the transplant. * Two days after transplant chemotherapy, patients will receive the transplant, with the two umbilical cords infused one after the other on the same day. Patients will receive additional treatment to prevent complications. * Patients will remain in the hospital for 4 to 6 weeks after the transplant, and will be discharged for outpatient treatment when the study doctors deem it appropriate. * Patients will continue on medications at home to lower the risk of complications and infections, and will visit the NIH clinic regularly for the first 6 months after the transplant, and then less often for at least 5 years afterward.

Umbilical Cord Blood Transplant, Cyclophosphamide, Fludarabine, and Total-Body Irradiation in Treating Patients With Hematologic Disease
Description

This phase II trial studies how well giving an umbilical cord blood transplant together with cyclophosphamide, fludarabine, and total-body irradiation (TBI) works in treating patients with hematologic disease. Giving chemotherapy, such as cyclophosphamide and fludarabine, and TBI before a donor umbilical cord blood transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after transplant may stop this from happening.

TERMINATED
Non-Myeloablative Bone Marrow Transplant for Patients With Sickle Cell Anemia and Other Blood Disorders
Description

RATIONALE: Giving low doses of chemotherapy, such as fludarabine and cyclophosphamide, and total-body irradiation before a donor bone marrow transplant helps stop the growth of abnormal cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving sirolimus and mycophenolate mofetil after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation followed by a donor bone marrow transplant works in treating patients with sickle cell anemia and other blood disorders.

Donor Peripheral Stem Cell Transplant and Donor Natural Killer Cell Transplant After Total-Body Irradiation, Thiotepa, Fludarabine, and Muromonab-CD3 in Treating Patients With Leukemia or Other Blood Diseases
Description

RATIONALE: Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell and donor natural killer cell transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When certain stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Removing the T cells from the donor cells before transplant may stop this from happening. PURPOSE: This phase II trial is studying how well giving a donor peripheral stem cell transplant and a donor natural killer cell transplant after total-body irradiation, thiotepa, fludarabine, and muromonab-CD3 works in treating patients with leukemia or other blood diseases.

TERMINATED
Umbilical Cord Blood T-Regulatory Cell Infusion Followed by Donor Umbilical Cord Blood Transplant in Treating Patients With High-Risk Leukemia or Other Hematologic Diseases
Description

RATIONALE: Giving chemotherapy, such as fludarabine and cyclophosphamide, and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer or abnormal cells and prepares the patient's bone marrow for the stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer or abnormal cells (graft-versus-tumor effect). Giving an infusion of the donor's T-regulatory cells before the transplant may help increase this effect. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase I trial is studying the side effects and best dose of umbilical cord blood T-regulatory cell infusion followed by donor umbilical cord blood transplant in treating patients with high-risk leukemia or other hematologic diseases.

When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil may stop this from happening. PURPOSE: This phase II trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation works in treating patients who are undergoing an umbilical cord blood transplant for hematologic cancer.

COMPLETED
Busulfan, Antithymocyte Globulin, and Fludarabine Followed By a Donor Stem Cell Transplant in Treating Young Patients With Blood Disorders, Bone Marrow Disorders, Chronic Myelogenous Leukemia in First Chronic Phase, or Acute Myeloid Leukemia in First Remission
Description

RATIONALE: Drugs used in chemotherapy, such as busulfan and fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. A donor peripheral blood, bone marrow , or umbilical cord blood transplant may be able to replace blood-forming cells that were destroyed by chemotherapy. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving antithymocyte globulin before the transplant may stop this from happening. PURPOSE: This phase I/II trial is studying the side effects of busulfan, antithymocyte globulin, and fludarabine when given together with a donor stem cell transplant in treating young patients with blood disorders, bone marrow disorders, chronic myelogenous leukemia in first chronic phase, or acute myeloid leukemia in first remission.

Collection of Tissue Specimens From Patients With Solid Tumors or Blood Disorders and Their HLA-Compatible Family Members
Description

This study will collect biological samples for use in research experiments aimed at better understanding the clinical features of certain diseases. The specimens may be used to evaluate the effectiveness of known therapies, refine treatment approaches, identify potential new therapies, and explore opportunities for disease prevention. The following individuals 2 years of age or older may be eligible for this study: * Patients with a cancerous solid tumor or a cancerous or non-cancerous blood disorder who are being screened for or who are enrolled in a treatment study at the NIH Clinical Center * HLA-compatible donor family members (18 years of age or older) of the above patients who are being evaluated for or are enrolled in an NIH study as a stem cell transplant donor * Patients with a cancerous solid tumor or a cancerous or non-cancerous blood disorder or a bone marrow failure condition who cannot participate in an NIH treatment protocol or travel to the NIH Clinical Center and who are referred for participation through their home health care provider. Research samples will be collected from participants when blood is drawn or bone marrow, urine, or stool is collected, or tumor or other tissue is biopsied as part of their general medical care. Investigators may periodically request an additional sample of blood, stool, or urine. Participants who are 18 years of age or older may donate a large number of white blood cells through a procedure called leukapheresis. This procedure is not part of general medical care and would be done for research purposes only. For apheresis, a catheter (plastic tube) is placed in a vein in the subject's arm. Blood flows from the vein into a cell separator machine, where the white cells are separated from the red cells, platelets, and plasma by a spinning process. The white cells are removed and collected, and the rest of the blood is returned to the subject through a second tube placed in the other arm.
