Precemtabart tocentecan
Based on 1 Customer Validation
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 (HY-P990940), 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.

Biological Activity
|
Topoisomerase I |
Precemtabart tocentecan (0.09-0.63 nM, 144 h) potently inhibits the viability of CEACAM5-positive SK-CO-1 and MKN45 cells, with IC50 values of 0.09 nM and 0.63 nM respectively[1].
Precemtabart tocentecan (1 nM, 6 days) induces cell death in CEACAM5-negative MDA-MB-231 cells when co-cultured with CEACAM5-positive SK-CO-1 cells, and the effect is enhanced with increasing number of SK-CO-1 cells[1].

Precemtabart tocentecan (4 mg/kg, i.v., once every 2 weeks for 3 doses) exerts potent antitumor activity in Irinotecan (HY-16562A)-pretreated CXF4102 CRC PDX model[1].

Animal Model:COPF230 or REPF210 tumor fragments were subcutaneously implanted into the right flanks of 5-6-week-old female immunodeficient mice[1]
-
Dosage:6 mg/kg
-
Administration:i.v., once on day 0
-
Result:Achieved tumor stasis (-29% tumor volume on day 52) in COPF230 model and tumor regression (-72% tumor volume on day 52) in REPF210 model.
