Precemtabart tocentecan

Precemtabart tocentecan (Precem-TcT; M 9140) is an anti-CEACAM5 (carcinoembryonic antigen-related cell adhesion molecule 5) antibody-drug conjugate (ADC). Precemtabart tocentecan consists of a tumor-specific anti-CEACAM5 monoclonal antibody Precemtabart , a highly hydrophilic and stable cleavable β-glucuronide linker, and a topoisomerase 1 inhibitor payload Exatecan (HY-13631), and the drug-linker conjugate for ADC is Mal-Gly-PAB-Exatecan-D-glucuronic acid (HY-153179). Precemtabart tocentecan inhibits the growth of CEACAM5-positive cancer cells. Precemtabart tocentecan exhibits significant antitumor activity in CEACAM5-expressing xenograft models. Precemtabart tocentecan can be used for the study of CEACAM5-expressing advanced solid tumors, especially mCRC[1].
