Filgotinib is a Janus kinase 1 (JAK1) inhibitor, that was reported in The Lancet to show positive results in patients with Crohn’s disease. Filgotinib is a “small molecule drug” that is taken by mouth & unlike the existing treatments for Crohn’s disease (biological agents such as infliximab & adalimumab) does not directly affect TNF but inhibits the activity of JAK1 & thereby reduces the inflammation causing Crohn’s disease.
In the study, 175 patients with moderate-to-severe Crohn’s disease were randomised to receive 200 mg filgotinib or placebo (a similar looking but inactive tablet). Filgotinib induced clinical remission in 48% of the patients, compared with 23% of the patients given placebo. In addition, more patients given filgotinib had an improvement in their quality of life (34%) than those given placebo (18%).
While there is still much work ahead, this Phase 2 study highlights filgotinib’s potential as an oral treatment for the treatment of Crohn’s disease.
