What is Loncastuximab?
Loncastuximab is a type of targeted cancer drug called an antibody-drug conjugate, which combines an antibody that finds cancer cells with a powerful cell-killing chemical. It is designed to treat a type of blood cancer called diffuse large B-cell lymphoma (DLBCL) in adults who have already tried other treatments. The antibody part seeks out a protein called CD19 found on certain cancer cells, delivering the toxic agent directly to them while limiting harm to healthy cells.
