Isatuximab (Novel monoclonal antibody)

Isatuximab (a novel monoclonal antibody that binds
selectively to CD38), which is widely expressed on the plasma
cells, and kills myeloma cells via multimodal mechanisms
including antibody-dependent cellular cytotoxicity,
antibody-dependent cellular phagocytosis, complement-
dependent cellular cytotoxicity, and immune cell
depletion or inhibition of immunosuppressive cells, as has been described with daratumumab.

 Additionally, isatuximab, similar to other CD38 antibodies, modulates
the NADase enzymatic activity of CD38.
However, isatuximab differentiates itself from daratumumab in its
ability to induce direct apoptosis without cross-linking, and in its binding epitope.

Isatuximab is approved in combination with pomalidomide and dexamethasone for adult patients with multiple myeloma who have received at least two prior therapies including lenalidomide and a proteasome inhibitor.

A pretty amazing mechanism, right?
