Provided is an antibody-drug conjugate for use in the treatment of G12D mutantKRAS-expressing cancer. Also provided is a drug-linker conjugate for use in the antibody-drug conjugate. The present inventors have made an antibody-drug conjugate capable of delivering a heterocyclic compound represented by formula (I) to cancer, such as EGFR-expressing cancer, by binding the compound to an antibody, such as an anti-EGFR antibody. Also discovered is a drug-linker conjugate for use in the antibody-drug conjugate or a salt thereof. The antibody-drug conjugate inhibits G12D mutantKRAS and exhibits an antitumor effect through the induction of the decomposition of G12D mutantKRASprotein in cancer, for example EGFR-expressing cancer.
Provided herein are methods of treating cancer in a subject in need thereof, comprising administering to the subject a therapeutically effective amount of a combination of a RTK-MAPK pathway inhibitor and a compound of Formula (I).
Antibody formulations are described comprising a mixture of an anti-α4β7 antibody, an antioxidant or chelator, and at least one free amino acid. The disclosed formulations may have improved stability, reduced aggregate formation, or both. The present invention further provides a safe dosing regimen of these antibody formulations that is easy to follow, and which results in a therapeutically effective amount of the anti-α4β7 antibodyin vivo.
