Active clinical trials for "Hemoglobinuria"

This is a Phase 3b, single-arm, open-label, multicenter study to evaluate the efficacy, safety, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of eculizumab in adult participants with paraxysmal noturnal hemoglobinuria (PNH) in China.

The purpose of this study is to evaluate the safety, tolerability, immunogenicity, pharmacokinetics, pharmacodynamics, and efficacy of KP104 in complement inhibitor-naïve participants with PNH. The study will be conducted in 2 parts. Part 1 is a dose-selection study to assess escalating doses and varying dose intervals of KP104. Part 2 is a proof-of-concept (POC) study assessing the efficacy of the optimal intravenous (IV) loading dose followed by the optimal maintenance dose and regimen of KP104. Participants who complete the Initial Treatment Period and demonstrate benefit from KP104 will be eligible for a 9-month open-label extension (OLE) treatment period.

Background: Severe aplastic anemia (SAA), and myelodysplastic syndrome (MDS), and paroxysmal nocturnal hemoglobinuria (PNH) cause serious blood problems. Stem cell transplants using bone marrow or blood plus chemotherapy can help. Researchers want to see if using peripheral blood stem cells (PBSCs) rather than bone marrow cells works too. PBSCs are easier to collect and have more cells that help transplants. Objectives: To see how safely and effectively SAA, MDS and PNH are treated using peripheral blood hematopoietic stem cells from a family member plus chemotherapy. Eligibility: Recipients ages 4-55 with SAA, MDS or PNH and their relative donors ages 4-75 Design: Recipients will have: Blood, urine, heart, and lung tests Scans Bone marrow sample Recipients will need a caregiver for several months. They may make fertility plans and a power of attorney. Donors will have blood and tissue tests, then injections to boost stem cells for 5-7 days. Donors will have blood collected from a tube in an arm or leg vein. A machine will separate stem cells and maybe white blood cells. The rest of the blood will be returned into the other arm or leg. In the hospital for about 1 month, recipients will have: Central line inserted in the neck or chest Medicines for side effects Chemotherapy over 8 days and radiation 1 time Stem cell transplant over 4 hours Up to 6 months after transplant, recipients will stay near NIH for weekly physical exams and blood tests. At day 180, recipients will go home. They will have tests at their doctor s office and NIH several times over 5 years.

The primary objective of the study is to describe the long-term safety, tolerability, and efficacy of pozelimab and cemdisiran combination therapy in patients with PNH The secondary objectives of the study are to describe the long-term effect of the combination of pozelimab and cemdisiran on: Measures of intravascular hemolysis Transfusion parameters Hemoglobin levels Fatigue as assessed by a Patient Reported Outcome (PRO) Physical Function (PF) as assessed by a PRO Change in Global Health Status (GHS) as assessed by a PRO Complement activation Concentrations of total pozelimab in serum and cemdisiran and total complement component 5 (C5) protein in plasma Immunogenicity of pozelimab & cemdisiran

The purpose of this study is to evaluate the safety, effectiveness, and biological activity (how the investigational medication is processed by the body) of pegcetacoplan in 12-17 year-olds (adolescents) who have paroxysmal nocturnal hemoglobinuria (PNH).

This study is designed to provide continued access to BCX9930 for subjects currently receiving treatment with BCX9930 in a BioCryst-sponsored clinical study for paroxysmal nocturnal hemoglobinuria (PNH) who, in the opinion of the investigator, would benefit from continued treatment with BCX9930 and who do not have access to other treatment options.

The study is researching a clinical treatment combination with two experimental drugs called pozelimab and cemdisiran. The study is focused on patients with paroxysmal nocturnal hemoglobinuria (PNH). The aim of the study is to see how safe and effective the pozelimab + cemdisiran combination is for patients with PNH and how the combination compares with 2 existing treatments, one called ravulizumab and the other called eculizumab. The pozelimab + cemdisiran combination may be referred to as "study drugs". Ravulizumab and eculizumab may also be called the "comparator drug". The study is looking at several research questions, including: How effective is the pozelimab + cemdisiran combination compared to ravulizumab? How effective is pozelimab + cemdisiran combination compared to eculizumab? What side effects may happen from taking the study drugs? How much study drugs are in your blood at different times? Whether the body makes antibodies against the study drugs (which could make the study drugs less effective or could lead to side effects)

The purpose of this study is to assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy in patients with Paroxysmal Nocturnal Hemoglobinuria (PNH).

The main purpose of this study is to evaluate the efficacy of MY008211A in adult patients with PNH , showing signs of active hemolysis, in China.

The purpose of this study is to assess the safety, tolerability, pharmacokinetics, pharmacodynamics and preliminary efficacy of OMS906 for the treatment of Paroxysmal Nocturnal Hemoglobinuria (PNH) in patients who have a sub-optimal response to ravulizumab.
