Brief Summary:
This was a phase 2 study to evaluate the safety and efficacy of elsubrutinib (ELS) and ABBV-599 (ELS plus upadacitinib \[UPA\]) vs placebo on a background of conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) for the treatment of signs and symptoms of rheumatoid arthritis (RA) at 12 weeks in biological disease-modifying anti-rheumatic drugs (bDMARD)-inadequate response (bDMARD-IR) or bDMARD-intolerant participants with moderately to severely active RA and to define optimal dose for further development.
Detailed Description:
This was a 12-week, randomized, double-blind, parallel-group, Phase 2, dose exploratory, multicenter study. Participants who met eligibility criteria were randomized in a 3:2:2:2:2:1 ratio to 1 of 6 treatment groups: ABBV-599 \[UPA 15 mg/ELS 60 mg\]); ELS 60 mg/UPA placebo; ELS 20 mg/UPA placebo; ELS 5 mg/UPA placebo; UPA 15 mg/ELS placebo; and ELS placebo/UPA placebo. The study included a 35-day maximum screening period and a 12-week treatment period with 30-day follow-up.
