ATHN Transcends: A Natural History Study of Non-Neoplastic Hematologic Disorders

In parallel with the growth of ATHN's clinical studies, the number of new therapies for all blood disorders is increasing significantly. Some of the recently FDA-approved therapies for congenital and acquired hematologic conditions have not yet demonstrated long-term safety and effectiveness beyond the pivotal trials that led to their approval. In addition, results from well controlled, pivotal studies often cannot be replicated once a therapy has been approved for general use.2,3,4,5 In 2019 alone, the FDA has issued approvals for 24 new therapies for congenital and acquired hematologic conditions.6 In addition, almost 10,000 new studies for hematologic diseases are currently registered on www.clinicaltrials.gov.7 With this increase in potential new therapies possible, it is imperative that clinicians and clinical researchers in the field of non-neoplastic hematology have a uniform, secure, unbiased, and enduring method to collect long-term safety and efficacy data. As emphasized in a recently published review, accurate, uniform and quality national data collection is critical in clinical research, particularly for longitudinal cohort studies covering a lifetime of biologic risk.8

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.

A Research Study Looking at Long-term Treatment With Etavopivat in People With Sickle Cell Disease or Thalassaemia

Etavopivat is a new medicine under development for treating blood disorders like sickle cell disease and thalassaemia. Sickle cell disease and thalassaemia are inherited blood disorders that affect haemoglobin. Haemoglobin is the protein that carries oxygen through the body. This study is looking into how safe treatment with etavopivat is and how well it works over a long period of time. The study will last for up to 264 weeks, but it will end earlier if etavopivat is approved in the participant's country.

A Study of Immune Suppression Treatment for People With Sickle Cell Disease or β-Thalassemia Who Are Going to Receive an Allogeneic Hematopoietic Cell Transplantation (HCT)

Hematopoietic Cell Transplantation/HCT involves receiving healthy blood-forming cells (stem cells) from a donor to replace the diseased or damaged cells in participants' bone marrow. The researchers think giving participants treatment with fludarabine and dexamethasone, drugs that lower the activity of the body's immune system (immune suppression), before standard conditioning therapy and HCT may help prevent serious side effects, including graft failure and GvHD. In this study, depending on how participants' body responds to the fludarabine and dexamethasone, the study doctor may decide participants should receive another drug, called cyclophosphamide, instead of fludarabine. In addition, depending on the results of participants' routine blood tests, participants may receive the drugs bortezomib and rituximab, which also help with immune suppression.

Determination of Red Cell Survival in Sickle Cell Disease and Other Hemoglobinopathies Using Biotin Labeling

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....

Effect of Exercise on Body Composition and Bone Health in Patients With Thalassemia

The goal of this clinical trial is to determine if a weight bearing exercise intervention can improve body composition and bone health in adolescents and adults with Thalassemia. The main questions it aims to answer are: * Does participation in a 12-week weight bearing exercise intervention change total body lean mass and percentage body fat (as assessed by DXA) in adolescents and adults with Thalassemia? * Does participation in a 12-week weight bearing exercise intervention change muscle function (assessed by hand grip strength, sit to stand and vertical jump) and endurance (assessed by the 6 minute walk test) in adolescents and adults with Thalassemia? * Does participation in a 36 week weight bearing exercise intervention (30 min/day; 5x/week) change bone mineral density as assessed by DXA in adolescents and adults with Thalassemia? Researchers will compare participants' change in body composition, muscle mass, and muscle function during a "Usual Activity" period (12 weeks) with an exercise intervention (Period 1: 12 weeks) to see if exercise can improve body composition and muscle function. The intervention will then be extended an additional 24 weeks for a total of 36 weeks of exercise (Period 2) to explore the change in bone mineral density between between "Usual Activity" and "Exercise Intervention" (Period 2) in individuals with Thalassemia. During the intervention period, participants will engage in a self-directed exercise regime of either weight bearing aerobic exercise or strength training exercises (30 min/day; 5x/week).

European Rare Blood Disorders Platform (ENROL)

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

RADeep Multicenter European Epidemiological Platform for Patients Diagnosed With Rare Anemia Disorders (RADs)

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.

Effect of Folic Acid Supplementation in Pregnant Women Having Thalassaemia Trait

Folic acid supplementation has been recommended for prevention of neural tube defects in pregnancy when taken periconceptionally up to 12 weeks of gestation. A daily dose of 0.4mg has been endorsed by World Health Organisation to achieve a Red blood cell (RBC) folate level of 906nmol/L (400ng/mL) for reduction of neural tube defect. Hong Kong has no policy on food fortification. Research data conducted in countries with food fortification may not be applicable. It is therefore essential to study the baseline folate status in pregnant women locally. For pregnant women with thalassaemia, they are believed to have a higher risk of folate deficiency because of an increased rate of erythropoiesis and chronic haemolysis. However, information on folate level of thalassaemia trait in pregnancy is scanty. Unmetabolized folic acid has been detected in maternal and fetal blood when daily dosage greater than 0.8-1mg was taken. In term of the dosage and duration of folic acid supplementation after 12 weeks of gestation, the practice varies widely among public hospitals and Maternity \& Child Health Care centres. It is therefore essential to study the optimal dosage of folic acid supplementation in women with thalassaemia.
