The monoclonal antibody anselamimab binds to immunoglobulin-associated amyloid in an effort to promote phagocytosis and clearance of the amyloid deposits.

In a phase I study (NCT02245867), 27 patients with deep hematologic responses to myeloma therapy, but persistent organ involvement, received anselamimab.[35]This treatment is not approved by the U.S. Food and Drug Administration and is under clinical evaluation.[35][Level of evidence C3]
