Moxetumomab pasudotox, sold under the brand name Lumoxiti, is an anti-CD22 immunotoxin medication for the treatment of adults with relapsed or refractory hairy cell leukemia (HCL) who have received at least two prior systemic therapies, including treatment with a purine nucleoside analog.[2][3][4] Moxetumomab pasudotox is a CD22-directed cytotoxin and is the first of this type of treatment for adults with HCL.[4] The drug consists of the binding fragment (Fv) of an anti-CD22 antibody fused to a toxin called PE38.[5] This toxin is a 38 kDa fragment of Pseudomonas exotoxin A.

Hairy cell leukemia (HCL) is a rare, slow-growing cancer of the blood in which the bone marrow makes too many B cells (lymphocytes), a type of white blood cell that fights infection.[4] HCL is named after these extra B cells which look “hairy” when viewed under a microscope.[4] As the number of leukemia cells increases, fewer healthy white blood cells, red blood cells and platelets are produced.[4]
