TALVEY® is the first and only FDA-approved bispecific antibody developed to target GPRC5D1,2

The heterogeneous nature of multiple myeloma highlights the need for new treatment targets3

Different targets may help address treatment resistance and avoid reexposure to previous targets4–6 

  • With emerging research, GPRC5D has been identified as a target with a potential role in cancer treatment5,6
  • GPRC5D is expressed on the surface of multiple myeloma cells and non-malignant plasma cells. It is also expressed on healthy tissues such as epithelial cells in keratinized tissues of the skin and tongue1,5,7–10
  • Expressed in a broad range of patients with multiple myeloma that varied according to disease staging, cytogenetic abnormalities, gender, and age5
  • Expression is independent of other targets, including BCMA6

GPRC5D expression has limited to no known impact on healthy B cells, and is prominently found on malignant multiple myeloma cells5,9–11 

GPRC5D expression is not detected in early B cell lines, such as pro-B cells and early progenitor cell lines9

TALVEY® induces the lysis of multiple myeloma cells by activating the immune system via GPRC5D × CD31

  • In research that examined GPRC5D mRNA expression in malignant cells, GPRC5D mRNA was found to be substantially expressed in multiple myeloma cell lines3
  • This finding led to the commitment of Janssen Biotech, Inc., to pursue the development of a GPRC5D-targeting therapy for multiple myeloma4
