10 Clinical Trials for Hemoglobinuria, Paroxysmal
The purpose of this study is to evaluate the safety, effectiveness, and biological activity (how the investigational medication is processed by the body) of pegcetacoplan in 12-17 year-olds (adolescents) who have paroxysmal nocturnal hemoglobinuria (PNH).
The aim of this International PNH Interest Group (IPIG) registry is to develop an international database to prospectively collect data on patients with PNH covering clinical outcomes, patient reported outcomes (PROs), and health-resource utilization (HRU) on all enrolled patients, as well as long term safety data.
This study is researching a clinical treatment combination with two experimental drugs called pozelimab and cemdisiran. The study is focused on people with paroxysmal nocturnal hemoglobinuria (PNH). The aim of the study is to see how safe and effective the pozelimab + cemdisiran combination is for people with PNH and how the combination compares with 2 existing treatments: ravulizumab and eculizumab. The pozelimab + cemdisiran combination may be referred to as "study drugs". Ravulizumab and eculizumab may also be called the "comparator drug". The study is looking at several research questions, including: * How effective is the pozelimab + cemdisiran combination compared to ravulizumab? * How effective is pozelimab + cemdisiran combination compared to eculizumab? * What side effects may happen from taking the study drugs? * How much study drugs are in the blood at different times? * Whether the body makes antibodies against the study drugs (which could make the study drugs less effective or could lead to side effects)
The study aims to longitudinally capture the full spectrum of symptoms, treatment utilization, and overall Health-Related Quality of Life (HRQoL) experienced by PNH patients. By primarily utilizing home reported outcomes (HRO) data on symptom burden and treatment usage, supplemented with patient-reported outcome (PRO) measures, the study seeks to establish a new real-world data (RWD) source to understand symptom variability and HRQoL among PNH patients, including those receiving orally administered iptacopan.
The primary aim of the Global Paroxysmal Nocturnal Hemoglobinuria (PNH) Patient Registry is to conduct a prospectively-planned and efficient natural history study that will result in a more comprehensive understanding of the disease and its course and pace over time. Other registry objectives include the following: * Provide a convenient online platform for participants (or caregivers) to self-report cases of PNH. * Develop a communications registry within the Global PNH Patient registry (e.g., to notify patients of research studies and clinical trials). * Characterize and describe the Global PNH population as a whole, enhancing the understanding of disease prevalence and phenotype as well as the rate of progression of disease characteristics. * Assist the PNH community with the development of recommendations and standards of care. * Be a case-finding resource to be used for researchers who seek to study the pathophysiology of PNH, retrospectively collate intervention outcomes, and design prospective trials of novel treatments.
A phase II trial of a reduced intensity conditioned (RIC) allogeneic hematopoietic cell transplant (HCT) with post-transplant cyclophosphamide (PTCy) for idiopathic severe aplastic anemia (SAA), paroxysmal nocturnal hemoglobinuria (PNH), acquired pure red cell aplasia (aPRCA), or acquired amegakaryocytic thrombocytopenia (aAT) utilizing population pharmacokinetic (popPK)-guided individual dosing of pre-transplant conditioning and differential dosing of low dose total body irradiation based on age, presence of myelodysplasia and/or clonal hematopoiesis.
The primary objective of this study is to describe the frequency and characteristics of pregnancy outcomes and maternal complications among participants exposed to Ultomiris and to describe the frequency and characteristics of selected fetal/neonatal/infant outcomes in utero, at birth, and through 1 year of age after exposure in utero or via breastmilk.
Background: Severe aplastic anemia (SAA), and myelodysplastic syndrome (MDS), and paroxysmal nocturnal hemoglobinuria (PNH) cause serious blood problems. Stem cell transplants using bone marrow or blood plus chemotherapy can help. Researchers want to see if using peripheral blood stem cells (PBSCs) rather than bone marrow cells works too. PBSCs are easier to collect and have more cells that help transplants. Objectives: To see how safely and effectively SAA, MDS and PNH are treated using peripheral blood hematopoietic stem cells from a family member plus chemotherapy. Eligibility: Recipients ages 4-60 with SAA, MDS or PNH and their relative donors ages 4-75 Design: Recipients will have: * Blood, urine, heart, and lung tests * Scans * Bone marrow sample Recipients will need a caregiver for several months. They may make fertility plans and a power of attorney. Donors will have blood and tissue tests, then injections to boost stem cells for 5-7 days. Donors will have blood collected from a tube in an arm or leg vein. A machine will separate stem cells and maybe white blood cells. The rest of the blood will be returned into the other arm or leg. In the hospital for about 1 month, recipients will have: * Central line inserted in the neck or chest * Medicines for side effects * Chemotherapy over 8 days and radiation 1 time * Stem cell transplant over 4 hours Up to 6 months after transplant, recipients will stay near NIH for weekly physical exams and blood tests. At day 180, recipients will go home. They will have tests at their doctor s office and NIH several times over 5 years.
This is a single arm pilot study using TCR alpha/beta+ T cell-depleted peripheral blood stem cells (PBSC) from closely matched unrelated donors or partially matched/haploidentical related donors for hematopoietic stem cell transplant (HSCT) in patients with acquired and inherited bone marrow failure (BMF) syndromes.
Background: * Stem cell transplants from related donors (allogenic stem cell transplants) can be used to treat individuals with certain kinds of severe blood diseases or cancers, such as severe anemia. Allogenic stem cell transplants encourage the growth of new bone marrow to replace that of the recipient. Because stem cell transplants can have serious complications, researchers are interested in developing new approaches to stem cell transplants that will reduce the likelihood of these complications. * By reducing the number of white blood cells included in the blood taken during the stem cell collection process, and replacing them with a smaller amount of white blood cells collected prior to stem cell donation, the stem cell transplant may be less likely to cause severe complications for the recipient. Researchers are investigating whether altering the stem cell transplant donation procedure in this manner will improve the likelihood of a successful stem cell transplant with fewer complications. Objectives: - To evaluate a new method of stem cell transplantation that may reduce the possibly of severe side effects or transplant rejection in the recipient. Eligibility: * Recipient: Individuals between 4 and 80 years of age who have been diagnosed with a blood disease that can be treated with allogenic stem cell transplants. * Donor: Individuals between 4 and 80 years of age who are related to the recipient and are eligible to donate blood. OR unrelated donors found through the National Marrow Donor Program. Design: * All participants will be screened with a physical examination and medical history. * DONORS: * Donors will undergo an initial apheresis procedure to donate white blood cells. * After the initial donation, donors will receive injections of filgrastim to release bone marrow cells into the blood. * After 5 days of filgrastim injections, donors will have apheresis again to donate stem cells that are present in the blood. * RECIPIENTS: * Recipients will provide an initial donation of white blood cells to be used for research purposes only. * From 7 days before the stem cell transplant, participants will be admitted to the inpatient unit of the National Institutes of Health Clinical Center and will receive regular doses of cyclophosphamide, fludarabine, and anti-thymocyte globulin to suppress their immune system and prepare for the transplant. * After the initial chemotherapy, participants will receive the donated white blood cells and stem cells as a single infusion. * After the stem cell and white blood cell transplant, participants will have regular doses of cyclosporine and methotrexate to prevent rejection of the donor cells. Participants will have three doses of methotrexate within the week after the transplant, but will continue to take cyclosporine for up to 4 months after the transplant. * Participants will remain in inpatient care for up to 1 month after the transplant, and will be followed with regular visits for up to 3 years with periodic visits thereafter to evaluate the success of the transplant and any side effects.
