The data include 24 week results of the ongoing Phase 3 FINCH 1, 2, and 3 trials, and updated Week 156 safety data from the Phase 2b DARWIN 3 long term extension study in patients with RA.

Week 24 safety data from the FINCH 1, 2, and 3 studies are aggregated and summarized in the table below. Data from 3,452 patients are reported, including 2,088 patients who received filgotinib.

The Phase 2b DARWIN 3 long term extension trial initially enrolled 739 patients, who received filgotinib 100 mg twice daily, 100 mg or 200 mg once daily. Safety data are summarized in the table below. Results represent treatment through 156 weeks or longer, and comprise 2,203 patient-years of exposure (PYE) to filgotinib.

"The growing body of evidence from both the DARWIN 3 long-term extension trial combined with the results of the FINCH 1, 2, and 3 trials, represent a larger safety database in a broader population of RA patients, spanning from those who are treatment-naive to those who have failed biologics," said John McHutchison, AO, MD, Chief Scientific Officer, Head of Research and Development, Gilead Sciences.


"The available safety data from the FINCH and DARWIN 3 studies, which together included more than 2,700 patients receiving filgotinib, suggest that filgotinib has the potential to deliver a much needed option for treating people living with RA," said Dr. Walid Abi-Saab, Chief Medical Officer, Galapagos.


Filgotinib is an investigational agent and not approved anywhere globally. Its efficacy and safety have not been established.


About the FINCH program

The FINCH Phase 3 program is investigating the efficacy and safety of 100 mg and 200 mg filgotinib once daily, in RA patient populations ranging from early stage to biologic-experienced patients. FINCH 1 is a 52-week, randomized, placebo- and adalimumab-controlled trial in combination with methotrexate (MTX) enrolling 1,759 adult patients with moderately to severely active RA who have had inadequate response to MTX. The primary endpoint is ACR20 at week 12. The trial includes radiographic assessment at weeks 24 and 52. FINCH 2 was a 24-week, randomized, placebo-controlled trial in 449 patients who were receiving conventional disease-modifying anti-rheumatic drugs (cDMARD), and had a prior inadequate response to one or more biological therapies. The primary endpoint was ACR20 at week 12. FINCH 3 is a 52-week, randomized trial in 1,252 MTX-naïve patients to study filgotinib in combination with MTX, as well as monotherapy. The primary endpoint is ACR20 at week 24. Radiographic progression is also being assessed.


About the DARWIN 3 program

DARWIN 3 is an ongoing multi-center, open-label, long-term follow-up safety and efficacy trial of subjects who completed either DARWIN 1 or DARWIN 2, which were double-blind, placebo-controlled Phase 2b trials for 24 weeks of treatment in patients with moderate to severe RA who showed an inadequate response to methotrexate. DARWIN 1 (594 patients) evaluated filgotinib as an addition to methotrexate, as once- and twice-daily administration (once-daily and twice-daily dosing, respectively) at three daily dose levels. DARWIN 2 (283 patients) evaluated filgotinib as once-daily monotherapy administration (once-daily dosing) at three dose levels. Both DARWIN 1 and DARWIN 2 achieved the primary endpoints (ACR20).
