年齢と腎障害が選択的JAK1阻害薬であるフィルゴチニブの薬力学的安定性に及ぼす影響
Br J Clin Pharmacol 2018 Dec;84(12):2779-2789. DOI:10.1111/bcp.13726
Age and renal impairment (RI) had limited impact on the pharmacokinetics (PK) of filgotinib (FIL) but, in subjects with severe RI, exposure to the FIL metabolite was increased. FIL is a selective JAK1 inhibitor that is extensively, rapidly and proportionately absorbed after oral dosing from 50–200mg. Its major metabolite has a similar JAK1 selectivity profile but with reduced potency. In humans, exposure to the metabolite is higher by approximately 16–20 fold compared with the parent FIL. FIL an...
