Mouse xenograft models of human IL-6-producing tumours (e.g. H460 lung) with siltuximab; no MCD model
“In a study of mice bearing H460 human lung tumour xenografts, twice-weekly dosing with CNTO 328 (25 mg/kg) caused a reduction in tumour volume and a delay in time to tumour endpoint by 7.6 days compared to PBS control.”
EMA: in vitro and in vivo data sufficient to show anti-tumoral effect; MCD mouse model not necessary
“Available data from in vitro and in vivo studies with siltuximab are considered enough to conclude it has an anti-tumoral effect. Additional in vivo experiments in the mice model for MCD are not considered necessary.”
