Geo Regions

CEACAM5-directed Antibody Drug Conjugate

PF-08046050, SGN-CEACAM5C is an investigational compound. Its safety and efficacy have not been established.

Overview + Rationale

  • A member of the CEACAM sub-group family of glycoproteins involved in cell adhesion.1 
  • Highly expressed in several tumors of epithelial origin such as CRC, PDAC, GC, and NSCLC.2 
  • Normally expressed during fetal development but stops before birth and is restricted in adults.1,2 
  • CEACAM5C is an investigational antibody-drug conjugate, comprising a monoclonal antibody directed to CEACAM5 and a novel TOP1 inhibitor linker-payload system, which enables preferential release of a potent topoisomerase 1 inhibitor within target cells.3 
  • CEACAM5C is under investigation in advanced solid tumors.4
