Eli Lilly and Company LLY and Incyte Corporation INCY announced the presentation of 12-week results from a Phase IIb study of baricitinib, formerly LY3009104 (INCB28050), an orally available janus kinase (JAK) inhibitor, in patients with active rheumatoid arthritis (RA). The results were presented as a late-breaking oral presentation at the European League Against Rheumatism's (EULAR) Annual European Congress of Rheumatology [EULAR abstract LB0005: 12-Week Results of a Phase IIb Dose-Ranging Study of LY3009104 (INCB028050), an Oral JAK1/JAK2 Inhibitor, in Combination with Traditional DMARDs in Patients with Rheumatoid Arthritis]. The Phase IIb randomized double-blind, placebo-controlled, dose-ranging study, known as JADA, involved a total of 301 patients with active RA on stable doses of methotrexate. Patients were randomized to receive either placebo or one of four once-daily doses of baricitinib (1 mg, 2 mg, 4 mg or 8 mg) for 12 weeks.
