Another Her2 ADC competitor down for the count....

ADCT-502 was terminated today for safety, joining MEDI4276 as another potent next-gen ADC with potential in Her2-low expressing breast cancer that failed to live up to expectations this year. ADCT-502 was trastuzamab conjugated to a PBD payload at a DAR of 1.7.

DS-8201 remains the only real ADC competitor for XMT-1522 in Her2-low expressing MBC.
