Crizanlizumab Injection

Matthew Neal MD · FDA-approved active Small molecule

Crizanlizumab is a monoclonal antibody that binds to P-selectin on the surface of platelets and endothelial cells, blocking platelet-endothelial interactions and reducing vaso-occlusive crises in sickle cell disease.

Crizanlizumab is a monoclonal antibody that binds to P-selectin on the surface of platelets and endothelial cells, blocking platelet-endothelial interactions and reducing vaso-occlusive crises in sickle cell disease. Used for Sickle cell disease (reduction of vaso-occlusive crises in patients 16 years and older).

Mechanism of action

P-selectin is an adhesion molecule that mediates the interaction between platelets, red blood cells, and endothelial cells, contributing to vaso-occlusive events in sickle cell disease. By blocking P-selectin, crizanlizumab reduces the adhesion of sickle cells to the endothelium and decreases platelet activation, thereby reducing the frequency and severity of vaso-occlusive crises. This mechanism addresses a key pathophysiological process in sickle cell disease without directly affecting hemoglobin polymerization.
