GILEAD AND GALAPAGOS ANNOUNCE FILGOTINIB MEETS PRIMARY ENDPOINT IN THE PHASE 3 FINCH 3 STUDY IN METHOTREXATE-NA¤VE RHEUMATOID ARTHRITIS PATIENTS

28 March 2019 at 22:01 CET

-- Filgotinib 100 mg and 200 mg Plus Methotrexate (MTX) Demonstrated Significantly Higher ACR20/50/70 Responses Than Methotrexate Alone --

-- Filgotinib Safety Profile Consistent With Previously Reported Results --

 

Foster City, Calif. and Mechelen, Belgium; March 28, 2019; 22.01 CET; regulated information - Gilead Sciences, Inc. (NASDAQ: GILD) and Galapagos NV (Euronext & NASDAQ: GLPG) today announced Week 24 results of FINCH 3, an ongoing, randomized, double-blind, active-controlled Phase 3 study of filgotinib, an investigational, oral, selective JAK1 inhibitor, in adults with moderately-to-severely active rheumatoid arthritis. FINCH 3 evaluated filgotinib in combination with methotrexate and as monotherapy in MTX-na´ve patients. The study achieved its primary endpoint in the proportion of patients achieving an American College of Rheumatology 20 percent response (ACR20) at Week 24. The proportion of patients achieving the primary endpoint of ACR20 response at Week 24 was significantly higher for filgotinib 200 mg plus MTX and filgotinib 100 mg plus MTX compared with MTX alone. 

The proportion of patients achieving ACR50, ACR70, and clinical remission (DAS28(CRP) < 2.6) at Week 24 was also significantly higher for patients receiving once-daily filgotinib 100 mg or 200 mg plus MTX compared with patients receiving MTX alone. Additionally, those who received filgotinib experienced greater reduction in the Health Assessment Questionnaire Disability Index (HAQ-DI) compared with those receiving MTX alone at Week 24. Filgotinib 200 mg monotherapy inhibited the progression of structural damage at Week 24 compared with MTX alone as assessed by modified total Sharp score (mTSS).

Top-line FINCH 3 efficacy^ data are summarized in the table below:

The safety profile of filgotinib in FINCH 3 is consistent with prior studies up to Week 24. Serious adverse events occurred in 4.1 percent, 2.4 percent, 4.8 percent, and 2.9 percent of patients receiving filgotinib 200 mg plus MTX, filgotinib 100 mg plus MTX, filgotinib 200 mg monotherapy and MTX alone, respectively. There was one venous thrombotic event (in the MTX group), five cases of adjudicated major adverse cardiovascular events (two in the filgotinib 200 mg plus MTX group, one in the filgotinib 200 mg group and two in the MTX group) and one malignancy (in the MTX group). There was one death, reported in the filgotinib 200 mg plus MTX group. Serious infections occurred in 1.0 percent, 1.0 percent, 1.4 percent and 1.0 percent of the patients in the filgotinib 200 mg plus MTX, filgotinib 100 mg plus MTX, filgotinib 200 mg monotherapy and MTX groups, respectively. The proportion of patients reporting herpes zoster was 0.5 percent in each of the treatment groups.

"The FINCH 3 data clearly demonstrate improved efficacy when filgotinib is compared with the use of MTX alone in rheumatoid arthritis patients with earlier stages of disease," said John McHutchison, AO, MD, Chief Scientific Officer, Head of Research and Development, Gilead Sciences. "These data add to the body of evidence from our broader FINCH clinical study program, reinforcing the potential for filgotinib to address important therapeutic needs in people with rheumatoid arthritis."

"Additional effective and tolerable treatment options are still needed for people newly diagnosed with rheumatoid arthritis or in the early stages of the disease. This complements the FINCH 1 and FINCH 2 data, underlining the potential of filgotinib as a treatment option across a wide range of patient populations suffering from rheumatoid arthritis." said Dr. Walid Abi-Saab, Chief Medical Officer, Galapagos.

Detailed findings from FINCH 3 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.

About FINCH 3

FINCH 3 is an ongoing 52-week randomized, double-blind and active-controlled study examining filgotinib alone and in combination with MTX, enrolling 1,252 adult patients with moderately to severely active RA who are na´ve to MTX.  Patients were randomized (2:1:1:2) to receive filgotinib 200 mg plus MTX (n=417), filgotinib 100 mg plus MTX (n=207), filgotinib 200 mg alone (n=210) or MTX (n=418).  The primary endpoint is the proportion of patients who achieve an ACR20 response at Week 24.
