This clinical trial is focused on studying the effectiveness and safety of a treatment for a condition called warm autoimmune hemolytic anemia (wAIHA). This is a disease where the body’s immune system mistakenly attacks and destroys its own red blood cells, leading to anemia. The treatment being tested is a medication known as nipocalimab, which is a type of protein called a monoclonal antibody. This medication is given as a solution through an infusion into a vein.
The purpose of the study is to evaluate how well nipocalimab works in treating adults with wAIHA. Participants in the study will receive either nipocalimab or a placebo, which is a substance with no active medication. The study is designed to be double-blind, meaning neither the participants nor the researchers will know who is receiving the actual medication or the placebo during the initial phase. After this phase, there will be a long-term extension where all participants may receive nipocalimab.
Throughout the study, participants will have regular visits to monitor their health and the effects of the treatment. The study will assess whether the treatment can improve hemoglobin levels, which are important for carrying oxygen in the blood, without the need for additional rescue therapies. The study aims to provide valuable information on the potential benefits of nipocalimab for people living with wAIHA.
