Medical Uses
Moxetumomab pasudotox-tdfk (marketed as Lumoxiti), from AstraZeneca, is indicated for the treatment of adult patients with relapsed or refractory hairy cell leukemia (HCL) who have received at least two prior systemic therapies, including treatment with a purine nucleoside analog.
It is a CD22-directed antibody-drug conjugate: the antibody portion binds to CD22 on the surface of malignant B-cells, delivering a bacterial toxin (PE38) that is internalized and disrupts protein synthesis, leading to cell death.
