Gilead and Galapagos Announce Efficacy and Safety Results of Filgotinib Through 52 Weeks in Late-Stage Rheumatoid Arthritis Studies

FOSTER CITY, Calif. & MECHELEN, Belgium–(BUSINESS WIRE)–Gilead Sciences, Inc. (NASDAQ: GILD) and Galapagos NV (Euronext & NASDAQ: GLPG) today announced that Week 52 data from the registrational Phase 3 FINCH 1 and FINCH 3 trials of filgotinib, an investigational, oral, selective JAK1 inhibitor, for the treatment of moderately-to-severely active rheumatoid arthritis (RA) are consistent with and support the efficacy, safety and tolerability profiles demonstrated in the Week 12 and 24 analyses presented earlier this year.

“We are encouraged by the durability of both the efficacy and safety profiles of filgotinib seen in these studies,” said John Sundy, MD, PhD, Senior Vice President, Inflammation and Respiratory Diseases, Gilead Sciences. “These data suggest that filgotinib if approved, may play an important role in helping people living with rheumatoid arthritis achieve sustained, clinically meaningful responses.”

“These recent updates from the FINCH 1 and 3 trials continue to provide consistent evidence to support filgotinib’s profile in RA patients. In the second half of the FINCH 1 and FINCH 3 trials, filgotinib exhibited the same favorable safety profile seen in the first 24 weeks, including similar rates of thrombotic events as previously observed, as well as persistent efficacy,” said Dr. Walid Abi-Saab, Chief Medical Officer, Galapagos.

Detailed Week 52 results from the FINCH 1 and 3 trials will be submitted for presentation at a future medical conference.

A Marketing Authorization Application (MAA) for filgotinib for the treatment of adults with rheumatoid arthritis is now under evaluation by the European Medicines Agency (EMA) and a New Drug Application (NDA) for filgotinib has been submitted to the Japanese Ministry of Health, Labor and Welfare (MHLW). Gilead plans to file a New Drug Application (NDA) for filgotinib for the treatment of rheumatoid arthritis in the United States including the FINCH 1 and FINCH 3 Week 52 data later this year.

Filgotinib is an investigational agent and is not approved anywhere. Its efficacy and safety have not been established by any regulatory authorities.

About the FINCH 1 and FINCH 3 Programs

The FINCH Phase 3 program investigated 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 was 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 had inadequate response to MTX. The primary endpoint was ACR20 at week 12. The trial included radiographic assessment at weeks 24 and 52. FINCH 3 was a 52‑week, randomized trial in 1,252 MTX-naïve patients to evaluate filgotinib 200mg alone and filgotinib 100 mg or 200 mg combined with methotrexate versus methotrexate alone in methotrexate-naïve patients. The primary endpoint was ACR20 at week 24. Radiographic progression was also assessed.
