Active clinical trials for "Hemoglobinuria"

The primary objective of the study is to evaluate the safety and tolerability of pozelimab and cemdisiran combination therapy in participants with PNH who switch from eculizumab therapy The secondary objectives of the study are: To evaluate the effect of the combination treatment on the following parameters of intravascular hemolysis: lactate dehydrogenase (LDH) control, breakthrough hemolysis, and inhibition of CH50 To evaluate the effect of the combination treatment on the stability of LDH during the transition period from eculizumab monotherapy to combination with pozelimab and cemdisiran To evaluate the effect of the combination treatment on red blood cell (RBC) transfusion requirements To evaluate the effect of the combination treatment on hemoglobin levels To evaluate the effect of the combination treatment on clinical outcome assessments (COAs) measuring fatigue and health related quality of life (HRQoL) To assess the concentrations of total pozelimab and eculizumab in serum; and total cemdisiran and C5 protein in plasma To assess the immunogenicity of pozelimab and cemdisiran To assess safety after dose intensification To evaluate the long-term safety and efficacy of the combination treatment in an optional open-label extension period (OLEP)

This is a randomised Phase III, double-blind, multicentre, cross-over study to compare the efficacy, safety, pharmacokinetics, and immunogenicity between SB12 and Soliris® in subjects with PNH.

Evaluation of the Efficacy and Safety of Pegcetacoplan in Patients with Paroxysmal Nocturnal Hemoglobinuria .

This is a phase II, single-center study to evaluate the efficacy of a novel cytoreductive regimen followed by CD34+E- selected T cell depleted allogeneic stem cell (or soybean agglutinated and E-rosetted BM) transplant as treatment for patients with acute and chronic leukemias, lymphoma and myelodysplstic syndrome/PNH. The impact of the change in conditioning regimen and use of CD34-selected T cell depleted PBSCs on transplanted related morbidity and mortality and disease free survival will be assessed.

The purpose of this study is to transplant haploidentical related peripheral blood stem cells (PBSCs) that come from a relative such as a parent, sibling, a child or other relative who has a half-matched tissue type with the recipient (rather than being completely matched) following administration of a reduced-intensity regimen of busulfan, melphalan and alemtuzumab.

This study will evaluate the safety and effectiveness of the experimental drug eculizumab for treating paroxysmal nocturnal hemoglobinuria (PNH), a disorder that can cause premature destruction of red blood cells. PNH may result in anemia requiring blood transfusions. Patients may be at high risk of life-threatening blood clots in their veins and may have urine discoloration, stomach pain, difficulty swallowing, tiredness, and poor quality of life. Men may have problems getting or maintaining an erection. Eculizumab is a monoclonal antibody that may improve the survival of red blood cells in patients with PNH. Patients 18 years of age and older who have been diagnosed with PNH for more than 6 months, who have active disease, and who require blood transfusions may be eligible for this study. Each candidate is screened with a physical examination, electrocardiogram, blood and urine tests, and a questionnaire for information on how PNH affects the patient physically, socially, emotionally, and functionally. Participants receive infusions of eculizumab through a needle in a vein once a week for five doses and then every two weeks for another 24 doses. All patients are vaccinated against Neisseria meningitides, a bacteria that can cause symptoms, possibly including life-threatening meningitis, in susceptible people, including people who take eculizumab. At every treatment visit, patients update their health status, transfusion record, and medication use; review their laboratory results from the preceding visit; have vital signs measured; and provide a blood sample for laboratory tests. At selected visits, they also provide a urine sample, have a repeat electrocardiogram, and complete a questionnaire. At the final treatment visit, participants have a complete physical examination, in addition to the routine procedures.

The primary objective is to evaluate the safety of eculizumab in patients with transfusion-dependent hemolytic PNH

OBJECTIVES: I. Confirm the efficacy demonstrated in a pilot study using high dose cyclophosphamide in patients with severe aplastic anemia. II. Determine whether the addition of filgrastim (G-CSF) to high dose cyclophosphamide shortens the time to recovery in these patients. III. Determine whether this regimen is efficacious in treating paroxysmal nocturnal hemoglobinuria.

To determine the effectiveness of ACH-0144471 (also known as danicopan and ALXN2040) in improving anemia when given with eculizumab for 24 weeks in participants with PNH. Danicopan dose may be increased within each participant, to a maximum of 200 milligrams (mg) three times daily (TID) based on safety and efficacy at protocol-specified time points.

The primary purpose of this study is to evaluate the safety, tolerability, and efficacy of multiple intravenous (IV) doses of ravulizumab administered to complement inhibitor treatment-naïve participants with PNH.
