Representative data are presented. cytotoxicity in several target-negative cell lines compared with non-stressed ADCs. Notably, ADC aggregates with FcR-activation properties showed dramatically enhanced cytotoxicity in FcR-expressing cells. The FcR-mediated off-target cytotoxicity of ADC aggregates was reduced by using a FcR-blocking antibody or Fc-engineering for silencing Fc-mediated effector functions. Conclusions These…
