Filter by:The purpose of this study is to determine the efficacy and safety of BCX9930 monotherapy for the treatment of adult patients with PNH not currently receiving complement inhibitor therapy.
The purpose of this study is to determine the efficacy and safety of BCX9930 monotherapy for the treatment of PNH compared to continued C5 inhibitor therapy in adult PNH patients with residual anemia despite treatment with a C5 inhibitor.
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 phase II trial tests whether treosulfan, fludarabine, and rabbit antithymocyte globulin (rATG) work when given before a blood or bone marrow transplant (conditioning regimen) to cause fewer complications for patients with bone marrow failure diseases. Chemotherapy drugs, such as treosulfan, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Fludarabine may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. rATG is used to decrease the body's immune response and may improve bone marrow function and increase blood cell counts. Adding treosulfan to a conditioning regimen with fludarabine and rATG may result in patients having less severe complications after a blood or bone marrow transplant.
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).
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)
The purpose of this Phase 3 study was to determine whether iptacopan is efficacious and safe for the treatment of Paroxysmal nocturnal hemoglobinuria (PNH) patients who were naïve to complement inhibitor therapy.
The primary objective of the study is to evaluate the safety and tolerability of 2 dosing regimens of pozelimab and cemdisiran combination therapy during the open-label treatment period (OLTP) 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 total complement hemolysis activity (CH50) - To evaluate the effect of the combination treatment on hemoglobin levels - To evaluate the effect of the combination treatment on red blood cell (RBC) transfusion requirements - To evaluate the effect of the combination treatment on clinical outcome assessments (COAs) measuring fatigue and health related quality of life - To assess the concentrations of total pozelimab in serum and total complement component (C) 5 and cemdisiran in plasma - To assess immunogenicity to pozelimab and cemdisiran - To evaluate the long-term safety and efficacy of pozelimab and cemdisiran in an optional open-label extension period (OLEP) - To assess safety after treatment intensification with pozelimab and cemdisiran
This study is an open-label, single arm, multicenter, roll-over extension study to characterize long-term safety, tolerability and efficacy of iptacopan and to provide access to iptacopan to patients with PNH who have completed Novartis-sponsored Phase 2 or 3 studies with iptacopan
This study is designed to evaluate the long-term safety of daily oral treatment with BCX9930 in subjects who have participated in a previous BCX9930 trial for PNH and showed a benefit of treatment as determined by the Investigator. The study allows continued access to BCX9930 for enrolled subjects. The study will also evaluate the long-term effectiveness and impact on quality of life and general well-being of BCX9930 treatment, and the subject's satisfaction with the medication.
