Filter by:The primary objective of this study is to evaluate pharmacokinetics (PK) of ravulizumab administered subcutaneously via an on-body delivery system (OBDS) compared with intravenously administered ravulizumab in adult participants with PNH who are clinically stable on eculizumab for at least 3 months prior to study entry.
This is a Phase IIa, open-label, multiple dose, study in patients with PNH who have not received eculizumab (Soliris ®) in the past. A single cohort of subjects is planned for evaluation.
rVA576 for patients with Paroxysmal Nocturnal Hemoglobinuria (PNH).
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 4-60 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.
Evaluation of the Efficacy and Safety of APL-2 in Patients with 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.
This was a Phase 2, open label, single arm, multiple dose study to assess efficacy, safety, pharmacokinetics and pharmacodynamics of iptacopan when administered in addition to Standard of care (SoC) in patients with paroxysmal nocturnal hemoglobinuria (PNH) with signs of active hemolysis.
Coversin in Paroxysmal Nocturnal Hemoglobinuria (PNH) in patients with resistance to Eculizumab due to complement C5 polymorphisms.
The purpose of this study was to assess the pharmacokinetics (PK), pharmacodynamics (PD), safety, and efficacy of ravulizumab in pediatric participants with paroxysmal nocturnal hemoglobinuria (PNH).
This phase II trial studies how well fludarabine phosphate, cyclophosphamide, total body irradiation, and donor stem cell transplant work in treating patients with blood cancer. Drugs used in chemotherapy, such as fludarabine phosphate and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill cancer cells and shrink tumors. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. The donated stem cells may also replace the patient?s immune cells and help destroy any remaining cancer cells.
