EULAR Abs: Clean Filgo P2b 108-Wk LTE Data Quick Note Galapagos and partner Gilead are slated to present a poster with data from their long-term extension P2b study (DARWIN 3) with filgotinib (oral JAK1 inhibitor) in moderate-to-severely active rheumatoid arthritis on June 16, 2018 during a poster session at EULAR. The abstract (#SAT0200; Long Term Safety of Filgotinib in the Treatment of Rheumatoid Arthritis: Week 108 Data from a Phase 2B Open-Label Extension Study) highlighted an impressive long-term safety profile further solidifying filgotinib as the cleanest JAK1 inhibitor (see Fig. 1). Efficacy was also robust and durable with 68% achieving ACR50 and 72% achieving Low Disease Activity (per DAS28-CRP<3.2) at week 108 in 491 patients. This follows the disappointing baricitinib RA ADCOM, where concerns around a dose-dependent increase in VTE (DVT and PE) events shut down any likelihood of a 4mg approval (we don’t expect a 2mg approval either, see note). A second baricitinib CRL is a positive for GLPG, in our view, and will focus attention on upadacitinib’s nearly comparable VTE rate. We find the EULAR abstract top-line findings from DARWIN 3 LTE safety study to be encouraging and reaffirm our thesis that filgotinib is the best-in-class JAK1 inhibitor.
