A huge and exciting topic in the ADC world at the moment is ’non-traditional ADCS’. A non-traditional ADC uses the exact same concept of an ADC in the sense that it is made up of three components that join together and the ‘payload’ provides the killing power. However, one aspect of the ‘ADC’ is different to a traditional ADC, usually the antibody or the payload. Join this day to gain an update on the landscape of non-traditional ADCs.
