Promising results for Filgotinib’s clinical trials
Our expert's opinion
"Gilead and Galapagos (acquired by Gilead in 2015) are currently collaborating on Filgotinib, a biologic agent that could help treat and cure multiple diseases, such as Rheumatoid Arthritis, Crohn’s Disease, Ulcerative Colitis and Inflammatory Disease. The product is currently in Clinical Trials phase 3 for the first three of these diseases and Phase 2 for the inflammatory. This article shows the results for the trials for Rheumatoid Arthritis (called FINCH 2). They randomly, and secretely, divided the patients into 3 groups. Group A would received doses of 100mg of Filgotinib, group B would receive doses of 200mg and group C a placebo solution. This ensures that the results are the least biased. The results are good and few adverse events occured, which makes the product look more promising than it was. This is especially good because the population of patients chosen for FINCH2 trial are people with rheumatoid arthritis that didn’t repons well to other biologic treatments that are currently available or under clinical trials. I hope that results will continue to come out positive as this could give the sites of Gilead and Galapagos in Belgium more work and thus a need for new talents."

Gilead and Galapagos announce filgotinib meets primary and all key secondary endpoints in first phase 3 study in rheumatoid arthritis
Gilead Sciences, Inc. (NASDAQ: GILD) and Galapagos NV (Euronext & NASDAQ: GLPG) today announced that FINCH 2, a global, randomized, placebo-controlled, Phase 3 study of filgotinib, an investigational, selective JAK1 inhibitor, in adults with moderately-to-severely active rheumatoid arthritis and prior inadequate response/intolerance to biologic agents, achieved its primary endpoint in the proportion of patients achieving an American College of Rheumatology 20 percent response (ACR20) at Week 12. Also at Weeks 12 and 24, the proportion of patients achieving ACR50 and ACR70, low disease activity (LDA, DAS28(CRP) </equal to 3.2), and clinical remission (DAS28(CRP) < 2.6) were significantly higher for patients receiving once-daily filgotinib 100 mg or 200 mg compared to patients receiving placebo.
Filgotinib was generally well-tolerated in the FINCH 2 trial, with no new safety signals compared to those reported in previous trials of filgotinib. Treatment-emergent adverse events and serious adverse events were mostly mild or moderate in severity. Serious adverse events occurred in 3.4, 5.2 and 4.1 percent of the patients in the placebo, 100mg and 200mg groups, respectively. The proportion of patients who discontinued study drug due to treatment-emergent adverse events was also similar across groups. Two cases of uncomplicated herpes zoster were reported in each filgotinib group. Two major adverse cardiovascular events (MACE) were identified, one subarachnoid hemorrhage in the placebo group and one myocardial ischemia in the filgotinib 100 mg group. There was one case of non-serious retinal vein occlusion in the filgotinib 200 mg group and no reports of deep venous thrombosis (DVT) or pulmonary embolism (PE). There were no deaths, malignancies, gastrointestinal perforations, or opportunistic infections, including active tuberculosis.
Detailed findings from the FINCH 2 study will be submitted for presentation at a future scientific conference.
"Gilead is committed to the development of new therapies that offer meaningful benefit for people living with rheumatoid arthritis and other serious inflammatory diseases," said John McHutchison, MD, Chief Scientific Officer, Head of Research and Development, Gilead Sciences. "These initial Phase 3 data support the potential of filgotinib, in combination with select disease modifying drugs, to help patients with active rheumatoid arthritis who do not adequately respond to current biologic disease modifying agents. These data are particularly encouraging as we look ahead to Phase 3 results from the ongoing FINCH 1 and 3 trials, which are exploring filgotinib in other populations of patients with rheumatoid arthritis."
"We are pleased that filgotinib has demonstrated significantly improved clinical responses in this difficult to treat population," said Dr. Walid Abi-Saab, Chief Medical Officer at Galapagos. "The good tolerability in this study is also very encouraging."
Filgotinib is investigational and not approved anywhere globally. Its efficacy and safety have not been established. For information about the clinical trials with filgotinib: www.clinicaltrials.gov.
