ANTI-TROP2 ANTIBODY-DRUG CONJUGATE

摘要

The purpose of the present invention is to provide an antitumor drug that excels in antitumor effect and safety, and that has an excellent therapeutic effect. Provided is an antibody-drug conjugate characterized in that an antitumor compound represented by a formula and anti-TROP2 antibody are linked via a linker having a structure represented by the formula -L1-L2-LP-NH-(CH2)n1-La-(CH2)n2-C(=O)- (wherein anti-TROP2 antibody bonds with the L1 terminal and the antitumor compound bonds with the carbonyl group of the -(CH2)n2-C(=O)- moiety using the nitrogen atom of the amino group at position 1 as the bonding site).
