Aprutumab
Based on 1 Customer Validation
Aprutumab (BAY 1179470) is a fully human fibroblast growth factor receptor 2 (FGFR2)-specific monoclonal antibody. Aprutumab induces FGFR2 endocytosis and degradation in cancer cells expressing FGFR2. Aprutumab serves as the targeted monoclonal antibody component of the antibody-drug conjugate BAY 1187982 (HY-141600) and mediates the endocytosis of the antibody-drug conjugate into FGFR2-positive cells. Aprutumab can be used for the research of FGFR2-positive solid tumors, including studies on gastric cancer and triple-negative breast cancer.

In Vitro
Aprutumab specifically binds to human FGFR2 protein with a Kd value of 75 nM[1].
Aprutumab binds to FGFR2 proteins from multiple non-human species (mouse, rat, dog, pig, rhesus monkey) with an EC50 of 0.25-0.35 nM[1].
Aprutumab (5-24 h) specifically induces FGFR2 internalization in FGFR2-positive SUM-52PE and SNU-16 cancer cells, but exerts no such effect in FGFR2-negative MDA-MB-231 cells[1].
Aprutumab (10 μg/mL; 5 h) reduces FGFR2 expression on the surface of SNU-16 gastric cancer cells, confirming antibody-induced endocytosis[1].
Aprutumab (6 h) colocalizes with early endosome (Rab7) and lysosome (LAMP1) markers in approximately 60% of viable SUM-52PE cells, indicating that it is transported to lysosomes for degradation[1].
After conjugation to form BAY 1187982, Aprutumab retains its binding affinity for the FGFR2 antigen, with an EC50 of 0.29 nM[1].
