Figure 3From: Control of hyperuricemia in subjects with refractory gout, and induction of antibody against poly(ethylene glycol) (PEG), in a phase I trial of subcutaneous PEGylated urate oxidaseTwo pharmacokinetic patterns after single subcutaneous injections of PEG-uricase. (a) 'Long-circulating' group: eight subjects with uricase activity present in plasma at 21 days after injection. (b) 'Early elimination' group: five subjects with undetectable plasma uricase activity beyond 10 days after injection. The keys indicate the dose of PEG-modified recombinant mammalian urate oxidase (PEG-uricase).Back to article page
