Anti-drug antibodies: animals
ADA to surrogate REGN646 in monkeys accelerated clearance, especially at low concentrations; no ADA-associated toxicity
“The presence of ADA in animals in the REGN646 monkey study clearly impacted the rate of drug clearance observed in the study especially at lower concentrations, and there was no evidence of toxicity associated with the occurrence of ADA.”
~7% ADA with DUPIXENT in 16-week and 52-week AD studies (placebo 2% and 8%)
“In the 16-week studies, approximately 7% of subjects treated with DUPIXENT and 2% of subjects on placebo developed antibodies to dupilumab, while in the 52-week study, approximately 7% of subjects treated with DUPIXENT + TCS and 8% of subjects on placebo + TCS developed antibodies to dupilumab.”
In vitro whole-blood cytokine release far below alemtuzumab/TGN1412 controls; no effects on monkey TDAR, lymphocyte subsets or serum cytokines; ADA in some monkeys
