Chimeric Antigen Receptors with MAGE-A4 Specificity and Uses Thereof

Abstract:

MAGE-A4, or Melanoma-Associated Antigen A4, is a cancer-testis antigen (CTA) on the X chromosome. The present disclosure provides MAGE-A4-specific chimeric antigen receptors and cells expressing such chimeric antigen receptors. In certain embodiments, engineered cells expressing the chimeric antigen receptors of the present disclosure are capable of inhibiting the growth of tumors expressing MAGE-A4. The engineered cells of the present disclosure are useful for the treatment of diseases and disorders in which an upregulated or induced MAGE-A4-targeted immune response is desired and/or therapeutically beneficial. For example, engineered cells expressing the MAGE-A4-specific chimeric antigen receptors of the present disclosure are useful for the treatment of various cancers.
