Highly immunogenic in rabbits; significant antigenicity in monkeys, even within the eye
“It is therefore not surprising that it is highly immunogenic in rabbits as shown in the single-dose ocular toxicity studies. A significant antigenicity was observed also in monkeys, even within the eye.”
Serum levels >1000-fold below vitreous in rabbits and monkeys; aqueous humour and retina 2.5-4-fold below vitreous
“In rabbits and monkeys, serum levels were >1000-fold lower than vitreous concentrations. The levels in aqueous humour and retina were 2.5 – 4-fold lower than the vitreous levels.”
Highly immunogenic in rabbits; significant antigenicity in monkeys, even intraocular; most monkeys with perivascular sheathing were ADA-positive
“It is therefore not surprising that it is highly immunogenic in rabbits as shown in the single-dose ocular toxicity studies. A significant antigenicity was observed also in monkeys, even within the eye.”
Antibodies in approximately 1%-9% of patients after 6 to 24 months of monthly dosing; pre-treatment 0%-5%
“The pre-treatment incidence of immunoreactivity to LUCENTIS was 0%-5% across treatment groups. After monthly dosing with LUCENTIS for 6 to 24 months, antibodies to LUCENTIS were detected in approximately 1%-9% of patients.”
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
