Fig.4 Pharmacokinetic analysis of IBI112 in hFCRN(SD) rat. (A) Body weight. (B) Pharmacokinetic analysis parameters. On Day 0, Sprague-Dawley (SD) rats and hFcRn(SD) transgenic rats were intravenously injected via the tail vein with IBI112 (hIgG1 Fc) and the YTE-modified IBI112 antibody (5 mg/kg), respectively. Blood was drawn at the indicated times, and serum was obtained for pharmacokinetic analysis (n=3 females, 6-8 weeks old). The results revealed a significantly prolonged half-life of the YTE-modified IBI112 antibody in hFcRn(SD) rats compared to wild-type (WT) SD rats.
