Filgotinib doses in combination with MTX have shown improved signs, symptoms and physical function in patients with RA and limited or no prior MTX exposure. FIL 200mg monotherapy did not have a superior ACR20 response rate versus MTX. This 52-week, phase 3 study evaluated FIL in 1252 patients with RA. Patients were randomised to FIL 200mg + MTX or FIL 100mg + MTX, FIL 200 mg monotherapy, or MTX monotherapy. The primary endpoint was the proportion patients achieving ACR20 at week 24. Safety was...

Filgotinib improved RA signs and symptoms, physical function, and inhibited radiographic progression. FIL 200mg plus MTX, but not FIL 100mg plus MTX showed non-inferiority to ADA plus MTX, based on DAS28(CRP) low disease activity. FIL was also well tolerated in RA patients with inadequate response to MTX. This 52-week, phase 3 randomised clinical trial (FINCH 1) evaluated the efficacy and safety of FIL in patients with RA randomised to FIL 200 or 100mg, ADA 40mg, or placebo, all with background...
Among RA patients with an inadequate response or intolerance to bDMARDs, filgotinib (FIL) doses, compared to PBO resulted in significantly greater proportions achieving a clinical response at Wk12. Patients with active RA despite treatment with bDMARD therapy need treatment options. The FINCH 2 Phase 3 study compared the effects of FIL vs PBO for the treatment of RA patients with inadequate response or intolerance to ≥1 prior bDMARDs. Patients were randomized in a 1:1:1 ratio, receiving FI...

EULAR 2019 Abstract LB0003 Presentation
Filgotinib is an orally administered, selective inhibitor of JAK1. Filgotinib has shown good efficacy and was well tolerated for the treatment of RA in Phase 2 and 3 studies evaluating MTX-IR or bDMARD-IR patients. The objective of this study was to compare the efficacy and safety of filgotinib with and without MTX in patients with RA who were naïve to MTX therapy.

EULAR 2019 Abstract LB0001 Presentation
Filgotinib is an orally administered, selective inhibitor of JAK1. Filgotinib has shown good efficacy and was well tolerated for the treatment of rheumatoid arthritis (RA) in Phase 2 studies.The objective of this Phase 3 study was to evaluate the efficacy and safety of filgotinib treatment in patients with RA who have had an inadequate response to methotrexate (MTX).
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 pare...

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 week...

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...
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 placebo&s...
Filgotinib (GLPG0634) is a selective inhibitor of JAK1 currently in development for the treatment of RA and Crohn’s disease. This paper describes the pharmacokinetics of filgotinib and its active metabolite, as well as the PK/PD modelling to support dose selection for phase IIB. Two phase I, randomised, double-blind, placebo-controlled trials in healthy volunteers and one phase IIa proof-of-concept study in RA patients were used to evaluate single and multiple doses of filgotinib. Resul...
