Study Details

The purpose of this study was to assess efficacy, including inhibition of radiographic progression, and safety with upadacitinib versus placebo and versus an active comparator, adalimumab, in adults with with moderately to severely active rheumatoid arthritis (RA) who are on a stable background of methotrexate (MTX and who have an inadequate response to MTX.

Arms

• Placebo Comparator: Placebo followed by ABT-494
  Participants were to receive placebo to upadacitinib orally once daily (QD) and placebo to adalimumab by subcutaneous injection once every two weeks (eow) for up to 26 weeks. Participants who did not achieve a ≥ 20% improvement in tender joint count (TJC) and swollen joint count (SJC) at Weeks 14, 18, or 22 compared to Baseline were to be switched to 15 mg upadacitinib orally QD. At Week 26, all remaining participants were to be switched to 15 mg upadacitinib QD until Week 48 (end of Period 1). Participants who complete Period 1 will continue to receive 15 mg upadacitinib orally QD for up to 5 years in Period 2.
• Active Comparator: Adalimumab
  Participants were to receive placebo to upadacitinib orally QD and 40 mg adalimumab by subcutaneous injection eow for up to 48 weeks in Period 1. Participants who did not achieve a ≥ 20% improvement in TJC and SJC at Weeks 14, 18, or 22 compared to Baseline were to be switched to 15 mg upadacitinib orally QD. At Week 26 remaining participants who did not achieve low disease activity (defined as Clinical Disease Activity Index \[CDAI\] ≤ 10) were to be switched to 15 mg upadacitinib orally QD until Week 48. Participants who complete Period 1 will continue to receive the same treatment assigned at the end of Period 1 (15 mg upadacitinib QD or 40 mg adalimumab eow) for up to 5 years in Period 2.
• Experimental: Upadacitinib
  Participants were to receive 15 mg upadacitinib orally QD and placebo to adalimumab by subcutaneous injection eow for up to 48 weeks in Period 1. Participants who did not achieve a ≥ 20% improvement in TJC and SJC at Weeks 14, 18, or 22 compared to Baseline were to be switched to 40 mg adalimumab eow. At Week 26 remaining participants who did not achieve low disease activity (defined as CDAI ≤ 10) were to be switched to 40 mg adalimumab eow until Week 48. Participants who complete Period 1 will continue to receive the same treatment assigned at the end of Period 1 (15 mg upadacitinib QD or 40 mg adalimumab eow) for up to 5 years in Period 2.
