Hemoglobinopathy

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.

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 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.

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 treatment's overall safety and efficacy.

Researchers are evaluating DISC-3405, a drug being studied in adults with sickle cell disease (SCD). This open-label, multicenter study focuses on examining up to three dose levels of DISC-3405 to assess its safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) in participants with SCD. The study is led by Disc Medicine, Inc and aims to better understand how this drug behaves and affects blood markers in people with this condition. Participants will receive DISC-3405 administered by subcutaneous injection in a within-participant dose escalation design. The study will explore up to three different doses of the drug to observe how participants respond to each level. This approach allows researchers to evaluate safety and drug effects at increasing dose amounts. The study lasts up to 36 weeks and includes multiple assessments during this time. Throughout the study, participants will undergo regular monitoring of safety and tolerability as the primary outcome. Researchers will also measure changes in blood-related markers like hemoglobin, hematocrit, reticulocyte count, red blood cell count, lactate dehydrogenase, and bilirubin. Pharmacokinetic measures such as drug concentration over time, maximum plasma concentration, elimination half-life, and clearance will also be tracked. Participants must be able to comply with study procedures, including providing informed consent and attending all visits during the trial period.

Researchers are studying etavopivat, a new medicine, in children aged 12 to 16 years with sickle cell disease who have an increased risk of stroke. The trial focuses on patients with conditional or abnormal transcranial doppler (TCD) ultrasound results, assessing whether etavopivat is safe and helpful for these participants. The study is a Phase 2 open-label trial sponsored by Forma Therapeutics, Inc., aiming to understand the effect of etavopivat on blood flow velocities in brain arteries. Participants will be divided into two groups based on their TCD results and whether they are already taking the medication hydroxyurea. One group includes participants with abnormal or conditional TCD who are not on hydroxyurea, while the other group includes those with similar TCD results who are on a stable dose of hydroxyurea. All participants will take 400 mg of etavopivat orally once daily for 52 weeks, with the option to continue in a 48-week extension period to further monitor safety. Etavopivat is taken as two 200 mg tablets and may be taken with or without food. During the study, participants will visit the clinic frequently for monitoring. Assessments include measuring blood flow velocities in brain arteries using TCD at various time points, tracking changes in velocity categories, and monitoring safety. The study also includes evaluating blood counts and liver and kidney function. At the end of the treatment and extension periods, participants may be offered the chance to join another study to continue receiving etavopivat. Total participation can last up to about two years depending on extension and further studies.
