Filter by:This multicenter prospective study seeks to determine if daratumumab given, prior to HLA-identical sibling donor transplantation using alemtuzumab, low dose total-body irradiation, and sirolimus, can prevent pure red blood cell aplasia with an acceptable safety profile in patients with anti-donor red blood cell antibodies, achieving an event-free survival similar to transplanted patients without such antibodies.
Background: Sickle cell disease (SCD) is an inherited disorder of the blood. SCD causes red blood cells (RBCs) to die early. This can lead to a shortage of healthy cells. SCD and other blood disorders can be managed with drugs or cured with a bone marrow transplant. Researchers want to know how long RBCs survive in people with SCD and other blood disorders before and after treatment compared to those who had a bone marrow transplant. Objective: To learn how long RBCs survive in the body in people with SCD and other blood disorders compared to those whose disease was cured with a bone marrow transplant. Eligibility: People aged 18 years or older with SCD or another inherited blood disorder. People whose SCD or blood disorder was cured with a bone marrow transplant are also needed. Design: Participants will be screened. They will have a physical exam with blood and urine tests. Participants will have about 7 tablespoons of blood drawn. In the lab, this blood will be mixed with a vitamin called biotin. Biotin sticks to the outside of RBCs. This process is called "biotin labeling of RBCs." The next day, the participant s own biotin-labeled RBCs will be returned to their bloodstream. Participants will return regularly to have smaller blood samples (about 2 teaspoons) drawn. These samples will be tested to detect the percentage of cells that have biotin labels. These visits may be every 2 weeks, 4 weeks, or some other interval. Participants will continue this schedule for up to 20 weeks or until biotin can no longer be detected....
It is estimated that over 250,000 babies are born with sickle cell disease (SCD) annually in sub-Saharan Africa, and only 10% - 50% of them survive beyond five years of age. Data describing the magnitude of the sickle cell problem are lacking in most African countries. The available data on prevalence were mainly from older studies and small numbers of hospitalized patients. In Uganda, approximately 25,000 children are born with SCD but 70-80% die before their 5th birthday. Lehmann and Raper found 'sicklaemia' prevalence of 0.8% and 45% in the Sebei and Bambaa ethnic groups, respectively. A recent study found a SCT and SCD prevalence of 3% - 19% and 0% - 3%, respectively but this study addressed only 5 of Uganda's 111 districts and used a small convenience sample of children aged 6 - 60 months. The objective of this study is to determine the prevalence and map out the burden of SCT and SCD in Uganda.
ENROL, the European Rare Blood Disorders Platform has been conceived in the core of ERN-EuroBloodNet as an umbrella for both new and already existing registries on Rare Hematological Diseases (RHDs). ENROL aims at avoiding fragmentation of data by promoting the standards for patient registries' interoperability released by the EU RD platform. ENROL's principle is to maximize public benefit from data on RHDs opened up through the platform with the only restriction needed to guarantee patient rights and confidentiality, in agreement with EU regulations for cross-border sharing of personal data. Accordingly, ENROL will map the EU-level demographics, survival rates, diagnosis methods, genetic information, main clinical manifestations, and treatments in order to obtain epidemiological figures and identify trial cohorts for basic and clinical research. To this aim, ENROL will connect and facilitate the upgrading of existing RHD registries, while promoting the building of new ones when / where lacking. Target-driven actions will be carried out in collaboration with EURORDIS for educating patients and families about the benefits of enrolment in such registries, including different cultural and linguistic strategies. The standardized collection and monitoring of disease-specific healthcare outcomes through the ENROL user-friendly platform will determine how specialized care is delivered, where are the gaps in diagnosis, care, or treatment and where best to allocate financial, technical, or human resources. Moreover, it will allow for promoting research, especially for those issues that remain unanswered or sub-optimally addressed by the scientific community; furthermore, it will allow promoting clinical trials for new drugs. ENROL will enable the generation of evidence for better healthcare for RHD patients in the EU as the ultimate goal. ENROL officially started on 1st June 2020 with a duration of 36 months. ENROL is co-funded by the Health Programme of the European Union under the call for proposals HP-PJ-2019 on Rare disease registries for the European Reference Networks. GA number 947670
Rare Anaemia Disorders (RADs) is a group of rare diseases characterized for presenting anaemia as the main clinical manifestation. Different medical entities classified as RADs by ORPHA classification are most of them chronic life threating disorders with many unmet needs for their proper clinical management creating an impact on European health systems. RADs present diagnostic challenges and their appropriate management requires from specialised multidisciplinary teams in Centers of expertise. Although there are some examples of well-established national registries on RADs in EU, the lack of recommendations for Rare disease registries implementation and the lack of standards for interoperability has led to the fragmentation or unavailability of data on prevalence, survival, main clinical manifestations or treatments in most of the European countries.
This study is being done to learn about etavopivat, a once a day medicine taken by mouth in adolescents with sickle cell disease. The main goals are to study safety and how long etavopivat stays in the bloodstream, while also studying if there are benefits from taking etavopivat. Eligible participants who enter the study will start a 96-week treatment period. At the end of the 96 weeks, participants will have an end of study visit that occurs 4 weeks later. The participants will receive etavopivat every day throughout the treatment period.
REACH is a prospective, phase I/II open-label dose escalation trial of hydroxyurea for children with confirmed SCA between 3 and 10 years of age. The short-term goal is to obtain critical pilot data regarding the feasibility, safety, and benefit of hydroxyurea for children with SCA in multiple distinct research settings in Africa. Based on that information, the longer-term goal is to make hydroxyurea more widely available for children with SCA in Africa, particularly those identified with SCA through expanded newborn screening programs.
Sickle cell disease (SCD) refers to a group of hemoglobinopathies that include mutations in the gene encoding the beta subunit of hemoglobin. Within the umbrella of SCD, many subgroups exist, namely sickle cell anemia (SCA), hemoglobin SC disease (HbSC), and hemoglobin sickle-beta-thalassemia (beta-thalassemia positive or beta-thalassemia negative). Several other minor variants within the group of SCDs also, albeit not as common as the varieties mentioned above. It is essential to mention the sickle cell trait (HbAS), which carries a heterozygous mutation and seldom presents clinical signs or symptoms. Sickle cell anemia is the most common form of SCD
Background: Sickle cell disease (SCD) is a genetic disorder where red blood cells, that carry oxygen, are stiff and become stuck in small blood vessels. As a result, affected patients can experience severe pain and serious organ damage. SCD can be cured with a hematopoietic cell transplant (HCT), that is, when they receive blood stem cells from a family donor. But HCT can also have serious side effects, especially in people with organ damage. Researchers want to find ways to make HCT safer for everyone. Objective: To test a new combination of drugs (briquilimab, abatacept, and alemtuzumab), used along with radiation, in people undergoing HCT for SCD. Eligibility: People aged 16 and older with SCD. They must be eligible for HCT and have a family member who is a good donor match. Donors must be aged 4 and older. Design: Participants with SCD will be screened. They will have blood tests and tests of organs including their heart and lung function. Donors will have blood drawn. Participants with SCD will have a tube inserted into a blood vessel in their chest (intravenously). This line will remain in place up to 2 months; it will be used to draw blood and administer the donor cells and other medications. Briquilimab will be administered intravenously 1 time, along with other drugs used to prepare for HCT. Participants will receive abatacept 6 times, from just before they receive their donor cells until 6 months after. Participants will undergo radiation therapy and take other drugs that are standard for HCT. Most HCT recipients remain in the hospital for about 30 days after HCT. Follow-up visits will continue for 5 years....
