Influence of Age and Renal Impairment on the Steady State Pharmacokinetics of Filgotinib, a Selective JAK1 Inhibitor

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...

Efficacy and Safety of Filgotinib, a Selective Janus Kinase 1 Inhibitor, in Patients with Active Ankylosing Spondylitis (TORTUGA): Results from a Randomized, Placebo-controlled, Phase 2 Trial

Lancet 2018 Dec 1;392(10162):2378-2387. DOI 10.1016/S0140-6736(18)32463-2

In this first clinical trial of filgotinib in patients with active AS, filgotinib significantly reduced disease activity, and the signs and symptoms of AS compared with placebo. The TORTUGA trial was a randomized, double-blind, placebo-controlled, Phase 2 trial, that enrolled 263 adult patients from 30 sites in seven countries. Patients with active AS and an inadequate response or intolerance to two or more NSAIDs were assigned 1:1 to receive filgotinib 200 mg or placebo once daily for 12 weeks....

Efficacy and Safety of Filgotinib, a Selective Janus Kinase 1 Inhibitor, in Patients with Active Psoriatic Arthritis (EQUATOR): Results from a Randomised, Placebo-controlled, Phase 2 Trial

Lancet. 2018 Dec 1;392(10162):2367-2377. DOI 10.1016/ S0140-6736(18)32483-8

In this first clinical trial of filgotinib in patients with PsA, filgotinib was effective in treating the signs and symptoms of active PsA across various disease manifestations.The EQUATOR trial was a randomized, double-blind, placebo-controlled, Phase 2 trial, that enrolled 191 adult patients from 25 sites in seven countries. Patients with active moderate-to-severe PsA and an insufficient response or intolerance to at least one csDMARD were assigned 1:1 to receive filgotinib 200 mg or placebo o...

Effect of Filgotinib, a Selective JAK1 Inhibitor, with or without Methotrexate in Patients with Rheumatoid Arthritis: Patient-Reported Outcomes

Arthritis Res Ther 2018; 20(1):57 doi: 10.1186/s13075-018-1541-z

Patient-reported outcomes (PROs) from two, Phase 2b, filgotinib (FIL) studies, DARWIN 1 and 2, revealed that patients receiving FIL had improved and sustained PRO responses compared with placebo. With suboptimal RA treatment, patients lose joint functional ability, which heavily influences patient quality of life. The previously reported data from the DARWIN studies, concluded that patients given FIL achieved clinically relevant dose-dependent improvements compared with patients given placebo¹,²...
