Trastuzumab pamirtecan
Trastuzumab pamirtecan is DualityBio and BioNTech's HER2 antibody-drug conjugate, in phase 3 trials in breast cancers with high and with modest HER2 expression and in HER2-expressing endometrial cancer.
Overview
DualityBio's DB-1303, licensed to BioNTech as BNT323, is a HER2-directed antibody-drug conjugate with a topoisomerase I inhibitor payload. Phase 3 trials are testing it in metastatic breast cancer with high and with modest HER2 expression against standard chemotherapy or other HER2 conjugates and in advanced HER2-expressing endometrial cancer, where it received US breakthrough designation. It is one of several conjugates trying to improve on trastuzumab deruxtecan's payload chemistry and tolerability.
A HER2 antibody carrying a topoisomerase I inhibitor payload through a cleavable linker, the same design family as trastuzumab deruxtecan, with a bystander effect on neighbouring cells. Connects to HER2.
