Narsoplimab was first approved by the U.S. Food and Drug Administration (FDA) on December 24,2025, for the management of thrombotic microangiopathy following hematopoietic stem cell transplantation (TA-TMA) in children aged 2 years and older and adults. As a serious complication of hematopoietic stem cell transplantation (HSCT), TA-TMA is characterized by high mortality. TA-TMA is associated with endothelial injury and can activate the complement agglutinin pathway, where mannose-binding agglutinin-related serine protease-2 (MASP-2) is a key enzyme. Narsoplimab is a humanized monoclonal antibody that specifically binds to and inhibits MASP-2, thereby reducing complement activation in damaged tissues without compromising the beneficial role of complement in anti-infection. Multiple real-world studies have demonstrated a high response rate. This article provides an overview of the mechanism of action, pharmacodynamics, pharmacokinetics, clinical studies, and safety profile of Narsoplimab.
