Pacritinib, a Kinase Inhibitor of CSF1R, IRAK1, JAK2, and FLT3, in Adults and Pediatric Participants 12 Years of Age or Older With Myelodysplastic Syndromes or Myelodysplastic/Myeloproliferative Neoplasms

Background: Myelodysplastic syndrome (MDS) and myelodysplastic/myeloproliferative neoplasm (MDS/MPN) are blood disorders that can cause serious complications in children and adults. MDS and MDS/MPN can also progress to acute myeloid leukemia. Treatments for these disorders are risky and not always effective. Better treatments are needed. Objective: To test a study drug (pacritinib) in adults and children with MDS or MDS/MPN. Eligibility: Children (aged 12 to 17 years) and adults (aged 18 years and older) with MDS or MDS/MPN. Design: Participants will be screened. They will have a physical exam with blood tests. They will have tests of their heart function. They may have a bone marrow biopsy: An area over the hip will be numbed; a needle will be inserted to remove a sample of soft tissue from inside the hipbone. Pacritinib is a capsule taken by mouth. All participants will take the study drug 2 times a day, every day, in 28-day cycles. They will write down the date and time they take each capsule. Doctors will assign varying dosages of the drug to different participants. Participants will have clinic visits each week during cycle 1; every 2 weeks during cycle 2; and gradually increasing to every 3 months after cycle 13. Treatment will continue for up to 8 years. Bone marrow biopsies, heart tests, and other tests will be repeated at intervals throughout the study. Participants will also fill out questionnaires about their quality of life, the symptoms of their disease, and other topics.

Dexamethasone, Intravenous Injection of Human Immunoglobulin, and Increased Infusion of Mononuclear Cells to Reduce Donor Specific Antibodies in Haploid Hematopoietic Stem Cell Transplantation: a Prospective, Multicenter Study

This study tests whether a combination of three treatments - dexamethasone (a steroid), intravenous immunoglobulin (IVIG, a protein that helps the immune system), and an extra dose of donor mononuclear cells - can safely lower harmful antibodies called donor-specific antibodies (DSA) in patients who need a stem cell transplant from a half-matched (haploidentical) family donor. In these transplants, DSA are antibodies made by the patient's own body that attack the donor's stem cells. If DSA levels are high, the transplant is more likely to fail - the donor cells may not "take" (engraft). Currently, there is no single, simple, and reliable way to reduce DSA, and many existing methods have drawbacks. Based on our earlier experience in 11 patients, this three-part approach seemed to work well. All patients successfully engrafted, and DSA levels dropped quickly. Now we want to confirm these results in a larger, prospective, multicenter study. We plan to enroll 60 patients aged 18-65 with blood cancers or other blood disorders who need a haploidentical transplant, have DSA levels above 500 MFI (a measure of antibody strength), and have no other suitable donor available. Participants will receive: * Dexamethasone (25 mg/m²) for 4 days before transplant, * IVIG (1 g/kg) one day before transplant, * Extra mononuclear cells on transplant day - the extra amount depends on how high their DSA level is (low, medium, or high). The main goal is to see how many patients have primary graft failure (when the donor cells never engraft). We will also measure how long it takes for blood counts to recover, rates of graft-versus-host disease, survival, and side effects. All participants will be followed for 1 year. This study will help us find out whether this combination is a safe, simple, and effective way to improve transplant success for patients with DSA who have no other donor options.

Collection of Blood, Bone Marrow, Skin, Saliva, and Stool Samples From Healthy Volunteers Used for Comparative Analysis of Myeloid Malignancies

Background: Myelodysplastic syndromes (MDS) are disorders of blood stem cells that can develop into blood cancers. Treatment options are limited. To find better treatments, researchers need to better understand how MDS develops. To do that, they must be able to compare biospecimens from people with the disease to those of healthy people. Objective: This study will create a database of biospecimens collected from healthy volunteers. Eligibility: Healthy people aged 18 and older. Design: Participants will be screened. They will have a physical exam with blood and urine tests. Up to 5 types of samples will be collected on 1 or more days within 1 month of screening: Blood: Blood will be drawn by inserting a needle into a vein. Saliva: Participants will scrape the insides of their cheeks with a brush. Stool: Participants will be given a container to collect stool at home. They will use a prepaid envelope to mail in the sample. Bone marrow: A sample of the soft tissue inside the bones will be drawn out. The area to be biopsied, usually the lower back, will be numbed. A needle will be inserted through a small cut to remove the sample. Participants' pain will be monitored; additional numbing medicine may be used. Skin: A piece of skin about 1/6 of an inch across will be cut away. Stitches may be used to close the wound. Participants will return to the clinic to have the stitches removed. Participants do not have to provide all of the samples listed. They will give each sample only once.

Biocollection in MyeloDysplastic Syndrome (P-MDS)

Myelodysplastic syndromes (MDS) are chronic myeloid hemopathies characterized by ineffective hematopoiesis (with peripheral cytopenias) and which contrast with a marrow of normal richness. MDS is considered one of the four most common blood diseases. The incidence is estimated at 4,059 cases / year in 2012 with an average age of 78 years in men and 81 years in women (INCA report, Cancers in France in 2015). The incidence increases with lengthening of the lifespan. The main risk of MDS is transformation to acute leukemia in 30 to 40% of cases. Treatment options depend on clinical, hematologic and chromosomal abnormalities. The prognosis is considered to be at low or high risk of developing acute leukemia. This distinction will therefore have an impact on the therapeutic solution (s). MDS exhibit clinical, morphological and genetic heterogeneity. It is therefore necessary to form subgroups of patients to better understand the physiopathogenesis of this pathology. The constitution of a biocollection will make it possible to search for clinical and biological prognostic markers in order to identify patients progressing to acute myeloid leukemia.

Investigation of the Genetics of Hematologic Diseases

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.

Automated Total Marrow and Lymphoid Irradiation for Allogeneic Hematopoietic Cell Transplant

Intensive conditioning regimens used in allogeneic hematopoietic cell transplant (HCT) help to eliminate hematologic tumors and reduce the risk of relapse, but are also characterized by high toxicity. Total marrow and lymphoid irradiation (TMLI) is a specialized radiation technique that specifically targets marrow and lymphoid tissue to maximize antitumor efficacy while reducing off target toxicity. Despite these benefits, TMLI is technically challenging and time consuming. The radiation oncology team at Stanford has developed an automated TMLI platform to overcome these challenges. In this phase II trial, automation will be incorporated into a previously validated conditioning regimen of fludarabine/cyclophosphamide/TMLI HCT with post-transplant cyclophosphamide (PTCy) for graft-versus-host disease (GVHD) prophylaxis to confirm the feasibility and safety of automation in patients receiving allogeneic HCT for high-risk myeloid malignancies.
