BAFF Antibody Derived from Dal Porto JM, et al1; Kurosaki T, et al2; Mackay F and Schneider P.3


B-cell activating factor (BAFF) is a member of the tumor necrosis factor (TNF) family and has been shown to be an important survival factor for peripheral B cells. It is expressed as a membrane-bound type II transmembrane protein that can be cleaved from the membrane, generating a soluble protein fragment.3 BAFF has been implicated in conferring a survival advantage to B-cell malignancies, such as multiple myeloma.4


Tabalumab (LY2127399) is a fully human monoclonal antibody designed to have neutralizing activity against both membrane-bound and soluble BAFF.5

Clinical Development

Tabalumab is being investigated in a clinical trial in patients with multiple myeloma.
