SARCLISA

ISATUXIMAB-IRFC CD38-directed Antibody Interactions
Oncology Approved 2020-03-02

Sarclisa (isatuximab-irfc) is a CD38-directed cytolytic antibody indicated for the treatment of adult patients with multiple myeloma. It is used in combination with various therapeutic regimens for patients across different stages of the disease, including those with newly diagnosed multiple myeloma who are ineligible for autologous stem cell transplant. The drug is also approved for patients with relapsed or refractory disease and those who have received multiple prior therapies, including lenalidomide and a proteasome inhibitor. Sarclisa serves as a targeted immunotherapy designed to identify and eliminate malignant plasma cells.

How SARCLISA Works

Isatuximab-irfc is a monoclonal antibody that binds to the CD38 protein expressed on the surface of multiple myeloma cells. This binding triggers tumor cell death through direct apoptosis and the activation of immune effector mechanisms, such as antibody-dependent cell-mediated cytotoxicity and complement-dependent cytotoxicity. Additionally, the drug inhibits the enzymatic activity of CD38, activates natural killer cells, and suppresses regulatory T-cells to enhance the body's immune response against the tumor. When used with pomalidomide, the combination increases direct tumor cell killing and immune-mediated activity compared to using the drug alone.

SARCLISA Target & Pathway

Pro

Target

CD38 (Cyclic ADP Ribose Hydrolase) Cell Surface Marker

A protein highly expressed on multiple myeloma cells. Anti-CD38 antibodies target and kill myeloma cells through multiple mechanisms, becoming a backbone of myeloma treatment across disease stages.
