Antibody Sp. Action Value Parameter Reference polatuzumab vedotin Hs Binding - - 1 ⤷ [1]
Antibody Comments
The ADC iladatuzumab vedotin (DCDS0780A) is being developed by Hoffmann-La Roche for potential treatment of B-cell non-Hodgkin's lymphoma. It is being evaluated in Phase 1 clinical trial NCT02453087.

Immunopharmacology Comments

CD79B is a component of the multimeric B cell antigen receptor (along with CD79A and a membrane-bound antibody that acts as the antigen recognition moiety). The CD79A/B component is responsible for signal transduction. The B cell antigen receptor complex is reported to be involved in the pathogenesis of various B cell-derived lymphoid cancers [2-3]. Inhibitors of components of B cell receptor signalling are being pursued as novel therapeutics for lymphoid neoplasms, e.g.polatuzumab vedotin is an investigational antibody-drug conjugate targeting a toxic payload to CD79B +ve cells in various hematological malignancies.

General Comments
This protein contains an immunoglobulin (Ig)-like domain that resembles the antibody variable domain, that has been coined the 'V-set domain'. The genes for all human V-set domain containing proteins are listed in HGNC gene group 590.
