Indications
By Deruxtecan Preparation Trastuzumab deruxtecan drug is approved by the FDA for the treatment of patients with any HER2-positive advanced solid tumour (e.g., breast, gastric, and GOJ adenocarcinomas) and only after the patient has previously received other advanced treatments.
Mechanism of action
Deruxtecan is attached to the antibody by a peptide linker. After trastuzumab deruxtecan binds to HER2 found on malignant cells, it is internalized and linker cleavage occurs through the actions of lysosomal enzymes. After it is released through cleavage, DXd causes targeted DNA damage and apoptosis in cancer cells, due to the ability to cross cell membranes.
