No anti-drug antibodies detected in marmoset or mouse surrogate toxicity studies
“Regarding toxicokinetics, exposure to canakinumab or 01BSUR was demonstrated in each study. With the analysis method used, no anti-drug antibodies were detected.”
Small volume of distribution, low clearance; half-life 4-7 days in marmosets vs 17.4 days rhesus, 14.5 days mice
“Of note, with 4-7 days the elimination half-life of canakinumab in marmosets was shorter than in rhesus monkeys (17.4 days), mice (14.5 days) and humans (26 days).”
Immunosuppression/infection risk from IL-1 blockade, including in utero exposed infants
“Because IL-1 blockade may interfere with immune response to infections, risks and benefits should be considered prior to administering live vaccines to infants who were exposed to ILARIS in utero”
No anti-drug antibodies detected in marmoset or mouse surrogate studies; exposure demonstrated in each study
“Regarding toxicokinetics, exposure to canakinumab or 01BSUR was demonstrated in each study. With the analysis method used, no anti-drug antibodies were detected.”
ADA in about 1.4% (CAPS), 1.2% (SJIA) and 3.5% (gout flares); neutralizing <1% in gout flares
“Following treatment with ILARIS, antibodies against ILARIS were observed in approximately 1.4%, 1.2%, and 3.5% of the patients with CAPS, SJIA, and gout flares, respectively. Neutralizing antibodies were detected in < 1% of patients with gout flares.”
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
