Active clinical trials for "Hemoglobinuria, Paroxysmal"

This is a Phase I/II, first-in-human study consisting of four sequential parts and an open-label extension (OLE). The safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of single doses of crovalimab will be evaluated in healthy volunteers (HV) during part 1. The safety, tolerability, PK and PD of multiple doses of crovalimab will be evaluated in participants with paroxysmal nocturnal hemoglobinuria (PNH) in parts 2, 3, 4, and OLE of the study. Efficacy of crovalimab will be evaluated in Parts 2, 3, and 4.

The proposed study, NM8074-PNH-101, is a phase II, open-label, multi-dose, unicenter trial to evaluate the safety and efficacy of NM8074 in Soliris-treated PNH subjects.

Background: Bone marrow failure diseases are rare. Much is known about the diseases at the time of diagnosis, but long-term data about the effects of the diseases and treatments are lacking. Researchers want to better understand long-term outcomes in people with these diseases. Objective: To follow people diagnosed with acquired or inherited bone marrow failure disease and study the long-term effects of the disease and its treatments on organ function. Eligibility: People aged 2 years and older who have been diagnosed with acquired or inherited bone marrow failure or Telomere Biology Disorder. First degree family members may also be able to take part in the study. Design: Participants will be screened with a medical history, physical exam, and blood tests. They may have a bone marrow biopsy and aspiration. For this, a large needle will be inserted in the hip through a small cut. Marrow will be drawn from the bone. A small piece of bone may be removed. Participants may also be screened with some of the following: Cheek swab or hair follicle sample Skin biopsy Urine or saliva sample Evaluation by disease specialists (e.g., lung, liver, heart) Imaging scan of the chest Liver ultrasounds Six-Minute Walk Test Lung function test Participants will be put into groups based on their disease. They will have visits every 1 to 3 years. At visits, they may repeat some screening tests. They may fill out yearly surveys about their medicines, transfusions, pregnancy, bleeding, and so on. They may have other specialized procedures, such as imaging scans and ultrasounds. Participation will last for up to 20 years. ...

This is a 24-month multicenter, observational study designed to describe the real world effectiveness of pegcetacoplan in patients with PNH. Patients meeting the eligibility criteria will be enrolled in the study at the enrollment visit and followed prospectively for 24 (+/- 3) months. The scope of the study is to collect both retrospective and prospective data. The main part of the study will be prospective,collecting data on effectiveness, safety, patient- and clinician-reported outcomes and health care resource use.

This is a Phase II, open-label study designed to evaluate the safety, efficacy, and immunogenicity of NM8074 administered intravenously to adult patients with Paroxysmal Nocturnal Hemoglobinuria (PNH).

This is a Phase II, open-label study designed to evaluate the safety, efficacy, and immunogenicity of NM8074 in PNH patients undergoing complement-inhibitor therapy with Soliris.

This study will collect clinical response data on participants who were already treated with eculizumab for at least 26 weeks and who started ravulizumab treatment as a specific therapeutic strategy as per ordinary clinical practice.

This study is a collection of data to evaluate safety and characterize progression of Paroxysmal Nocturnal Hemoglobinuria (PNH).

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare acquired clonal hematological disorder, which can cause arterial or venous thrombosis. The frequency of PNH in young patients (< 50 years old) with embolic stroke (ESUS), transient ischemic attack (ETUS) or superior sagittal sinus cerebral venous thrombosis (SSS-CVTUS) of undetermined source, is currently unknown. This study proposes to recruit ESUS, ETUS, SSS-CVTUS patients to determine the frequency of PNH diagnosis confirmed by flow cytometry in these patient populations.

The multicenter collaborative clinical study conducted a systematic clinical observation in the treatment of bone marrow failure diseases via UCB&UC-MSCs , in order to observe its clinical efficacy and safety.
