Background In ph 2 studies, baricitinib (bari) improved disease activity with an acceptable safety profile in pts with active RA naïve to biologic DMARDs (bDMARDs).1,2
Objectives To report patient-reported outcomes (PRO) from a ph 3 study of bari in pts with active RA on 1 or 2 conventional DMARDs (cDMARDs) and an inadequate response or intolerance to ≥1 TNF inhibitors.
Methods Pts were randomized 1:1:1 to placebo (PBO) or bari (2 or 4 mg) QD for 24 wks. PROs are listed in the table. Analyses included ANCOVA, logistic regression, and nonparametric methods and compared bari 2 or 4 mg vs. PBO.
Results 527 pts were randomized. Assessment of PROs at baseline revealed severe impairment of physical function (HAQ-DI: 1.7-1.8) and QoL. Bari 2 and 4 mg resulted in statistically significant improvements from baseline vs. PBO in most PROs at 24 wks (Table).
Conclusions In this ph 3 study of pts with active RA on cDMARDs and an inadequate response to bDMARDs, bari was associated with significant improvement in most PROs through 24 wks compared to PBO.
