GILEAD AND GALAPAGOS ANNOUNCE FILGOTINIB MEETS PRIMARY AND KEY SECONDARY ENDPOINTS IN THE PHASE 3 FINCH 1 RHEUMATOID ARTHRITIS STUDY

 

Gilead Sciences, Inc. (NASDAQ: GILD) and Galapagos NV (Euronext & NASDAQ: GLPG) today announced Week 24 results of FINCH 1, an ongoing, randomized, double-blind, placebo- and active-controlled Phase 3 study of filgotinib, an investigational, oral, selective JAK1 inhibitor, in adults with moderately-to-severely active rheumatoid arthritis. FINCH 1 evaluated filgotinib versus adalimumab or placebo, on a stable background dose of methotrexate in patients with prior inadequate response to methotrexate. The study achieved its primary endpoint for both doses of filgotinib in the proportion of patients achieving an American College of Rheumatology 20 percent response (ACR20) compared to placebo at Week 12.

The proportion of patients achieving ACR50 and ACR70 response was also significantly greater for filgotinib compared with placebo at Week 12, for both doses. Patients receiving filgotinib 100 mg or 200 mg had a statistically significant reduction in the Health Assessment Questionnaire Disability Index (HAQ-DI) at Week 12 compared with those receiving placebo. The proportions of patients achieving clinical remission (DAS28(CRP) < 2.6) and low disease activity (DAS28(CRP) < 3.2) at Week 12 were significantly higher for patients in both filgotinib arms compared with placebo. When comparing low disease activity rates at Week 12, filgotinib 200 mg was non-inferior to adalimumab. Filgotinib 100 mg and 200 mg also significantly inhibited the progression of structural damage at Week 24 as assessed by change from baseline in modified total Sharp score (mTSS) compared with placebo.

Top-line FINCH 1 efficacy^ data are summarized in the table below.

The safety profile of filgotinib in FINCH 1 is consistent with prior studies up to Week 24. Serious adverse events occurred in 4.4 percent, 5.0 percent, 4.3 percent and 4.2 percent of the patients in the filgotinib 200 mg, filgotinib 100 mg, adalimumab and placebo groups, respectively. There were five deaths, two patients were assigned to the placebo group, two to the filgotinib 200 mg group and one to the filgotinib 100 mg group. Five patients with a malignancy were also reported -- three receiving placebo, one receiving adalimumab and one receiving filgotinib 100 mg, respectively. Three venous thrombotic events were observed (two in the placebo group, one in the filgotinib 200 mg group), and there were four adjudicated major adverse cardiovascular events, two in the placebo, one in the adalimumab and one in the filgotinib 100 mg groups. The proportion of patients with herpes zoster was similar across treatment groups (filgotinib 200 mg = 0.4 percent, filgotinib 100 mg = 0.4 percent, adalimumab = 0.6 percent, placebo = 0.4 percent), as was the rate of serious infections (filgotinib 200 mg = 1.7 percent, filgotinib 100 mg = 1.7 percent, adalimumab = 2.5 percent, placebo = 0.8 percent).


"These FINCH 1 data add to the favorable results obtained previously in the FINCH 2 study in patients with a prior inadequate response to biologic agents and reinforce the evidence supporting the potential of filgotinib to address unmet treatment needs in patients with rheumatoid arthritis," said John McHutchison, AO, MD, Chief Scientific Officer, Head of Research and Development, Gilead Sciences. "Across the FINCH program, the data continue to support filgotinib's potential as a JAK1 specific inhibitor that may provide clinically meaningful responses combined with a favorable safety profile in a wide range of people living with rheumatoid arthritis, including those in the early stages of disease and those who have tried standard therapies without success."

"Many patients living with rheumatoid arthritis are in need of new treatment options that are effective, well-tolerated, and convenient. We are excited about the strong efficacy and tolerability results with both doses of filgotinib," said Dr. Walid Abi-Saab, Chief Medical Officer, Galapagos. "We are particularly pleased with the results filgotinib shows on clinically meaningful endpoints such as clinical remission, ACR70 and radiographic progression, as well as with the encouraging safety profile."

Detailed findings from FINCH 1 will be submitted for presentation at a future scientific conference. Filgotinib is an investigational agent and not approved anywhere globally. Its efficacy and safety have not been established.

Note

About FINCH 1
FINCH 1 is an ongoing 52-week randomized, double-blind, placebo- and active-controlled study, enrolling 1,759 adult patients with moderately to severely active RA who have an inadequate response to MTX. Eligible patients were randomized (3:3:2:3) to receive filgotinib 200 mg (n=477), filgotinib 100 mg (n=480), adalimumab (n=325) or placebo (n=477) in addition to a stable dose of MTX. The primary endpoint of the study is the proportion of patients who achieve an American College of Rheumatology 20 percent improvement response (ACR20) at Week 12. At Week 24, all patients in the placebo arm who did not discontinue study drug were reassigned (1:1) to either filgotinib 100 mg or 200 mg.
