Our clinical program with filgotinib in UC
UC is an inflammatory bowel disease resulting in ulcerations and inflammation of the colon and rectum. Unlike CD, UC involves damaging inflammation of only the colon and rectum. According to GlobalData, there were 1.2 million patients being treated for ulcerative colitis in the 7 major markets, for a combined total sales of just over $5 billion in 2017. Although the introduction of anti-TNF biologics has improved the treatment of some patients, only 33% of patients will achieve long-term remission, and many patients lose their response to treatment over time. The medical need for improved efficacy is high and likely could be achieved by a new mechanism of action.
Gilead initiated the SELECTION Phase 2b/3 trial in UC with filgotinib in December 2016. SELECTION investigates efficacy and safety of 100 mg and 200 mg filgotinib once-daily compared to placebo in patients with moderately to severely active disease including those with prior antibody therapy failure. Gilead will recruit approximately 1,300 patients from the United States, Europe, Latin America, Canada, and Asia/Pacific regions. The SELECTION Phase 2b/3 trial in UC will include a futility analysis, serving as the Phase 2b part of this integrated Phase 2b/3 trial. The outcome of the futility analysis is expected to be reported in 2018. Men and women in SELECTION will be randomized to receive placebo, 100 mg or 200 mg filgotinib. In the United States, males may receive 200 mg if they failed at least one anti-TNF and vedolizumab.
