This NIH-sponsored study aims to characterize three biomarkers derived from 129Xe gas exchange MRI and understand how they change in response to interventions. The study focuses on markers derived from the interaction of 129Xe with pulmonary capillary red blood cells RBCs, specifically RBC transfer MRI, cardiogenic oscillations in 129Xe-RBC signal amplitude, and the 129Xe-RBC chemical shift. The study population includes healthy volunteers, patients scheduled to undergo transfusion or phlebotomy, patients with dyspnea, interstitial lung disease ILD, idiopathic pulmonary fibrosis IPF, non-specific interstitial pneumonias NSIP, chronic hypersensitivity pneumonitis cHP, sarcoid, chronic thromboembolic pulmonary hypertension CTEPH, and acute pulmonary embolism.

The GENESIS clinical study aims to map HLA genetic variation in the Greek population and evaluate possible correlations with selected underlying diseases. It is a multicenter, prospective, non-interventional clinical study targeting 12,000 subjects over an anticipated duration of 36 months, with the goal of creating a pilot HLA map for medical research and possible clinical applications. Each subject will complete one visit at a participating site and provide demographic information, including date of birth, gender, race, ancestry, height, and weight, as well as information about smoking or vaping, alcohol consumption, arterial blood pressure, diagnosed diseases, and current treatments. Recent clinical laboratory results from up to 12 months before sample collection may also be collected when available, including blood count, metabolic, liver enzyme, and biochemical parameters. Two buccal swabs will be collected from each subject for DNA extraction and HLA genotyping analysis. Selected DNA samples will also undergo low-pass whole genome sequencing to further investigate associations between the HLA region and autoimmune diseases. After the analysis is completed, an individualized ancestry report will be securely available to study subjects if they elect to access it.

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 Childrens 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.

Diffuse large B-cell lymphoma DLBCL is the most common and aggressive subtype of non-Hodgkin lymphoma, with rapid tumor growth and symptoms varying by tumor location. The disease is classified using advanced methods like immunohistochemistry and molecular testing to guide prognosis and personalized treatment. Despite standard immunochemotherapy curing 60-70% of patients, many experience treatment failure or relapse, and options after second-line therapies remain limited. This observational study examines treatment patterns, demographic, and clinical characteristics of DLBCL patients in the Middle East and Africa. It includes two patient groups those newly diagnosed and eligible for treatment, and those with relapsed or refractory DLBCL who have failed previous therapies. The study aims to explore access to novel therapies and understand real-world treatment approaches in these regions. Participants will be observed over 22 months, during which researchers will document treatment regimens, patient risk profiles, and access to new treatments. Data collection includes patient demographics, disease characteristics, and treatment outcomes. The study does not involve experimental treatments but gathers detailed information to inform future care strategies for DLBCL patients.

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 41 ratio within each dose group. The study has multiple ascending dose cohorts to test increasing doses of 9MW3011. This design helps researchers understand the drugs 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 interventions acceptability and feasibility. The study also monitors how well the diagnostic process steps are followed, the interventions 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.

Researchers are evaluating the safety, tolerability, and effectiveness of a gene therapy treatment called BD211 for patients aged 3 to 35 years with transfusion-dependent beta-thalassemia. This condition requires regular blood transfusions, and the study aims to assess how well the gene-modified stem cells work and how safely they can be used. The study is a Phase 1, open-label trial sponsored by Shanghai BDgene Co., Ltd., focusing on patients who need frequent transfusions and have limited treatment options. The treatment involves a single intravenous infusion of BD211, which consists of autologous CD34 hematopoietic stem cells that have been genetically modified with a lentiviral vector to produce healthy beta-globin. Participants receive one dose of at least 5 million cells per kilogram of body weight. The study includes an 18-month follow-up period to monitor safety endpoints and effectiveness, including the ability to reduce or eliminate the need for transfusions. During the study, participants undergo regular assessments to track neutrophil and platelet engraftment, transfusion independence, blood hemoglobin levels, ferritin levels, and the presence of the beta-globin protein in blood. Researchers also monitor for adverse events, survival rates, hospitalizations, and any signs of complications related to the gene therapy. Participants are expected to comply with scheduled visits, laboratory tests, and long-term follow-up assessments to help determine the treatments overall safety and efficacy.

Researchers are evaluating the treatment of anemia in patients with chronic kidney disease CKD who are on hemodialysis. This Phase III, investigator-blinded, randomized, multicenter study compares two drugs, efepoetin alfa and darbepoetin alfa, to see how well they maintain hemoglobin levels in these patients. The study aims to maintain hemoglobin between 10.0 gdL and 12.0 gdL, which is important for managing anemia in CKD. Participants will be randomly assigned in a 21 ratio to receive either efepoetin alfa or darbepoetin alfa. Both drugs are given by intravenous injection, typically after dialysis sessions. Efepoetin alfa is administered weekly from Day 1 to Week 28, with possible interval changes to one or two weeks from Week 29 to Week 52 based on investigator judgment. The study consists of three periods screening up to 28 days, treatment about 52 weeks, and a 4-week follow-up with phone contacts up to Week 56 or the last visit. During the study, participants will undergo regular assessments including hemoglobin level monitoring to evaluate the mean change between Week 20 and Week 28. Safety and efficacy are closely observed, with dosages adjusted to maintain target hemoglobin levels. Follow-up will include phone contacts to monitor participants up to Week 56. The total participation duration is approximately one year, starting from screening through treatment and follow-up.

Researchers are evaluating the safety and effectiveness of emapalumab for treating prolonged severe cytopenia in participants with large B-cell lymphoma LBCL who have received CAR T-cell therapy CART. This pilot study aims to assess how well emapalumab works to improve blood cell counts and to monitor its safety and tolerability. Additionally, the study explores biomarkers that may indicate response or resistance to the treatment. Participants will be assigned to one of two dose levels of emapalumab, given by infusion. Up to two planned doses are being studied initially, with about 16 to 32 participants enrolled in total. The dosing approach involves evaluating improvement in blood test results among early participants to decide whether to continue enrollment at a given dose or to increase the dose. Treatment cycles and dose adjustments are based on the participants responses. Throughout the study, participants will undergo tests such as blood counts and bone marrow biopsies before and after each treatment cycle. Researchers will monitor safety by tracking adverse events and other health measures for about one year after treatment. Participants may also have biomarkers assessed to understand the treatments effects better. The study lasts until the primary completion date, with ongoing evaluations to assess safety and efficacy.

This research aims to evaluate how human lactoferrin combined with low-dose iron affects iron levels, aerobic fitness, and lactate metabolism in women who exercise and have low iron stores. The study focuses on healthy menstruating women aged 18 to 45 years with serum ferritin below 35 gL, aiming to understand if lactoferrin can improve iron regulation and exercise outcomes. Iron deficiency is common in active women and can reduce oxygen delivery and exercise performance, making this study important for finding better supplementation methods. Participants will be randomly assigned to one of three groups for an 8-week period receiving 100 mg lactoferrin plus 5 mg iron daily, 300 mg lactoferrin plus 5 mg iron daily, or a placebo plus 5 mg iron daily. The study uses a triple-blind design where neither participants nor researchers know who receives which treatment. The intervention is oral supplementation taken daily, and participants will attend six visits including screening, baseline, and follow-ups at weeks 2, 4, 6, and 8. During the study, participants will undergo blood tests to measure iron biomarkers and blood parameters, along with assessments of aerobic capacity using treadmill tests measuring VO2peak, time to exhaustion, and blood lactate levels. Questionnaires will evaluate gastrointestinal symptoms, menstrual symptoms, quality of life, and recovery perception. Daily supplement adherence and any side effects will be monitored throughout. The primary outcome is the change in serum ferritin concentration over time, while secondary measures include changes in hemoglobin, hematocrit, red blood cell count, and exercise performance indicators.
