Anti-GPRC5D Monoclonal Antibody SAR446523

**Semantic type:** Amino Acid, Peptide, or Protein|Immunologic Factor|Pharmacologic Substance

**Definition:** A Fc-engineered immunoglobulin G1 (IgG1) monoclonal antibody directed against the tumor-associated antigen (TAA) human G-protein coupled receptor family C group 5 member D (GPRC5D), with potential immunomodulating and antineoplastic activities. Upon administration, anti-GPRC5D monoclonal antibody SAR446523 targets and binds to GPRC5D expressed on certain tumor cells. This results in an antibody-dependent cell-mediated cytotoxicity (ADCC) against GPRC5D-expressing tumor cells, thereby killing the cancer cells. GPRC5D is overexpressed on certain tumors, such as multiple myeloma, while minimally expressed on normal, healthy cells, and plays a key role in tumor cell proliferation.
