A Phase IIb Study of ABT-494, a Selective JAK-1 Inhibitor, in Patients With Rheumatoid Arthritis and an Inadequate Response to Anti-Tumor Necrosis Factor Therapy.

ABSTRACT:

Objective

To compare the efficacy and safety of ABT-494, a novel selective JAK-1 inhibitor, with placebo in patients with moderate-to-severe rheumatoid arthritis (RA) and an inadequate response or intolerance to at least 1 anti-tumor necrosis factor (anti-TNF) agent.

Methods

In this 12-week, double-blind, placebo-controlled, dose-ranging study, 276 RA patients receiving a stable dose of methotrexate (MTX) who had previously received treatment with at least 1 anti-TNF agent were randomized equally to receive immediate-release ABT-494 at 3, 6, 12, or 18 mg twice daily or matching placebo twice daily. The primary end point was the proportion of patients meeting the American College of Rheumatology 20% improvement criteria (achieving an ACR20 response) at week 12.
