Hemolytic Anemia

Researchers are studying biomarkers from 129Xe gas exchange MRI to understand how they change with different medical interventions. The study focuses on interactions between 129Xe and red blood cells in the lungs. Participants include healthy volunteers and patients with conditions like interstitial lung disease, pulmonary hypertension, acute or chronic pulmonary embolism, anemia, polycythemia, and dyspnea. The study uses hyperpolarized xenon gas inhaled in multiple doses followed by breath holds, alongside oxygen administration. Participants are grouped by treatment: those undergoing transfusion or phlebotomy, patients receiving oxygen for lung-related conditions or healthy volunteers, and those recently diagnosed with acute or chronic pulmonary embolism. Treatments and responses are monitored at baseline and various follow-up points. Participants will undergo MRI scans to measure red blood cell transfer, chemical shifts after oxygen delivery, and changes in red blood cell signal oscillations before and after treatment. The study includes visits up to 3–6 months after interventions to track changes. Researchers also monitor safety and participant adherence throughout the study, which lasts until mid-2028.

Researchers are studying the smallest effective dose of 131I-apamistamab to prepare patients with advanced sickle cell disease (SCD) for a bone marrow transplant. This is the first time 131I-apamistamab, an investigational drug not yet approved by the FDA, is being used as part of the conditioning regimen before an allogeneic stem cell transplant. The goal is to see if eliminating total body irradiation, which can cause long-term side effects, is possible while still allowing successful transplantation. Participants will receive 131I-apamistamab as an intravenous infusion about ten days before receiving donor stem cells. The dose will be either 100 mCi or 150 mCi based on the dose level. This drug replaces the usual conditioning treatments like chemotherapy, total body irradiation, and Campath antibody. Other treatments involved include sirolimus and Campath, given to support the transplant process. During the study, participants will undergo various assessments including blood tests to monitor graft success, immune recovery, hormone levels, and transplant-related complications up to seven years after transplant. Imaging with planar gamma camera will evaluate drug absorption. Follow-up includes checking for graft failure 42 days post-transplant and monitoring long-term safety. Total participation lasts several years to observe transplant outcomes and side effects.

Researchers are conducting the GENESIS clinical study to map the HLA genomic region in the Greek population and explore its possible links with various underlying diseases. This non-interventional, multicenter study aims to provide a pilot map of genetic variation in HLA that may be useful in medical research and clinical applications related to selected diseases. The study plans to include 12,000 participants over a total duration of 36 months. Each participant will attend one visit at a participating site during which they will provide demographic data, lifestyle information such as smoking and alcohol use, blood pressure measurements, details on diagnosed diseases and treatments, and recent laboratory test results if available. Buccal swab samples will be collected from each participant to extract DNA for HLA genotyping analysis. Selected samples will undergo further whole genome sequencing to investigate associations with autoimmune diseases. Participants will receive a personalized ancestry report after analysis completion. During the study visit, data collection includes demographic and health information, as well as laboratory and clinical test results from the past year. The genetic material from buccal swabs will be stored and processed for genetic analysis. Researchers will measure allele frequency of HLA alleles in the Greek population and assess the prevalence and risk associations of selected HLA-related diseases. The study's total duration is 36 months with results available at the end of this period.

Researchers are evaluating an experimental drug called ALN-CFB in adults with Paroxysmal Nocturnal Hemoglobinuria (PNH) who continue to have anemia despite treatment with a complement component C5 inhibitor. This Phase 1 and 2 study aims to assess the safety and tolerability of ALN-CFB compared to a placebo, while also examining how the drug affects levels of Complement Factor B (CFB) protein in the blood and its concentration over time. Participants will be randomly assigned to receive either ALN-CFB or a placebo following a single-ascending dose escalation design. The study includes a double-blind period where neither participants nor researchers know who receives the drug or placebo. The protocol will be updated to describe Part B after analysis of Part A data. During the study, participants will be monitored for treatment-emergent adverse events and their severity over one year. Researchers will measure ALN-CFB and its metabolites in plasma and urine, along with changes in CFB concentration from baseline. The study involves regular visits for assessments and safety monitoring, lasting up to 365 days.

This research aims to evaluate the long-term safety and effectiveness of CS-101 in participants who previously received CS-101 in an earlier study (CS-101-03). It focuses on individuals with beta-thalassemia who underwent treatment with this base-edited autologous hematopoietic stem cell transplantation. The study is led by the Children's Hospital of Fudan University and monitors participants up to two years after their infusion. Participants in this follow-up study have completed the initial CS-101-03 trial where they received the CS-101 infusion. This current study tracks their health and treatment outcomes for up to two years after the last six-month follow-up visit post-infusion. The study does not introduce new treatments but observes the long-term effects of the prior CS-101 therapy. During the study, participants will undergo evaluations for serious adverse events, death, new cancers or blood disorders, and whether they achieve transfusion independence for at least 12 consecutive months. Researchers will also monitor changes in fetal and total hemoglobin levels, and the genetic modification presence in blood and bone marrow cells. All assessments occur from the time of consent through two years post-infusion, with safety and efficacy carefully observed throughout this period.

This research follows patients with Hemoglobinopathy and Sickle Cell Disease who previously received BEAM-101, a gene-edited cell treatment, in an earlier study. The trial is a long-term observational follow-up to monitor safety and health outcomes over an extended period. It aims to gather important information about the long-term effects and risks after receiving BEAM-101 treatment. Participants in this study have received a single dose of BEAM-101 by intravenous infusion after a conditioning treatment with busulfan. This follow-up study will track their health for 13 years, adding up to 15 years from the initial treatment. Study visits will happen annually for the first 5 years, then every 3 years until year 11, with a final visit at year 15. Additionally, virtual or phone check-ins will occur every 6 months for the first 5 years, then annually thereafter. During the study, participants will undergo regular safety and efficacy assessments to monitor their health, including how well they remain free of severe sickle cell crises and their blood hemoglobin levels. Researchers will review long-term safety data and mortality over the 13 years. The study includes blood tests and other evaluations at scheduled visits and check-ins. Participation will last up to 15 years, with ongoing monitoring to understand the lasting impact of BEAM-101 treatment.

Researchers are conducting a real-world study to evaluate the impact of iptacopan on adult patients with paroxysmal nocturnal hemoglobinuria (PNH) in China. The study aims to assess treatment-related outcomes, disease management, and healthcare resource use, considering new standards for PNH care and the introduction of iptacopan. It includes patients who are either new to complement inhibitor therapy or those stable on C5 complement inhibitors like eculizumab. The study involves two patient groups: one with PNH patients never treated with complement inhibitors who are starting iptacopan, and another with patients stable on C5 complement inhibitors who will switch to iptacopan after its approval in China. Treatments are oral capsules of LNP023 (iptacopan), and patients must start iptacopan within 60 days of consenting. Participants must have documented vaccinations against Neisseria meningitidis and Streptococcus pneumoniae before starting treatment. Participants will be followed for at least 12 months, with assessments including hemoglobin levels, lactate dehydrogenase (LDH), absolute reticulocyte count (ARC), bilirubin, PNH clone size, and signs or symptoms related to PNH. Researchers will monitor treatment effects, adverse events, medication use, transfusions, and healthcare visits. Patient fatigue and work productivity will be evaluated using specific questionnaires, with data collected at baseline and regular intervals to understand iptacopan's real-world impact on disease and quality of life.

Researchers are studying the use of unlicensed cryopreserved cord blood units (CBUs) for transplantation in both pediatric and adult patients with various blood-related cancers and other disorders affecting the blood-forming system. This observational study aims to evaluate outcomes such as the recovery of a certain level of white blood cells after transplantation, as well as the incidence of infections, infusion reactions, survival rates, and graft-versus-host disease over time. The study involves patients receiving unlicensed CBUs at multiple U.S. transplant centers. These CBUs are used for patients with hematologic malignancies and other blood disorders. The protocol collects data on patients who receive these unlicensed transplant units, without administering a new treatment but observing the outcomes after transplantation. Participants will be monitored for neutrophil recovery at 60 and 100 days post-transplant, along with assessments of infection transmission, infusion reactions, survival one year after transplant, and occurrences of acute and chronic graft-versus-host disease. Platelet engraftment levels will also be tracked. The study includes patients of any age and follows them through the transplantation and recovery process to gather information on these key outcomes.

Researchers are evaluating 9MW3011, a drug being studied in patients with non-transfusion-dependent beta-thalassemia, a condition affecting blood production. This phase Ib, randomized, double-blind, placebo-controlled study aims to assess the safety, tolerability, how the drug moves and acts in the body, and immune responses to 9MW3011. The study involves 40 patients divided into four dose groups to explore these effects carefully. Participants will receive either 9MW3011 or a placebo through intravenous infusion in a 4:1 ratio within each dose group. The study has multiple ascending dose cohorts to test increasing doses of 9MW3011. This design helps researchers understand the drug's impact at different dose levels and compare it to a placebo under blinded conditions. During the study, participants will be monitored up to day 169 for adverse events, vital signs, physical exams, ECG results, and lab tests to evaluate safety. Researchers will measure drug levels in the blood, effects on iron metabolism markers, immune responses, and liver iron concentration. Participants will be involved in scheduled visits for assessments, tests, and safety monitoring throughout the study duration.

Researchers are evaluating a new combination of evidence-based interventions (EBIs) aimed at improving diagnostic safety and efficiency in primary care for patients with anemia and decreased glomerular filtration rate. The study is designed as a stepped wedge cluster randomized control trial to measure how these interventions affect patient safety and healthcare efficiency, while also assessing factors influencing their implementation such as acceptability, cost, and sustainability. The study compares an enhanced diagnostic team approach to usual care. The enhanced approach includes automated detection and tracking of abnormal test results, expanding the primary care team to include clinical pharmacists to guide anemia evaluation, and engaging patients through nurse navigators to increase their activation in the diagnostic process. The study involves several clinic groups that receive the intervention at different times, ranging from 12 to 24 months, with some initial control periods. Participants will have their diagnostic accuracy for causes of low hemoglobin and decreased glomerular filtration rate assessed within six months. Researchers will track time to diagnosis, appropriate test usage, treatment costs, and primary care physicians' views on the intervention's acceptability and feasibility. The study also monitors how well the diagnostic process steps are followed, the intervention's reach among patients, and sustainability in clinics over 2.5 years. Patient activation and clinic-level facilitators and barriers are evaluated through surveys and measures during the study period.
