<h3>Background:</h3> In patients (pts) with inadequate response to methotrexate, baricitinib (BARI) treated pts with rheumatoid arthritis (RA) reported significantly greater and more rapid pain relief, than pts treated with adalimumab and placebo [1]. RA-BE-REAL is a 3-year, multinational, prospective, observational study of adult pts with RA starting BARI or any biologic or other targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs). <h3>Objectives:</h3> To assess the association of patient-reported pain and remission or low disease activity (LDA) at 3-month (M) in pts receiving BARI or other treatments, in RA-BE-REAL. <h3>Methods:</h3> The analyses report on pts with RA who were prescribed, for the first time, BARI (cohort A) or a tumor necrosis factor inhibitor (TNFi) (cohort B-TNFi) or any other mode of action treatment (cohort B-OMA) including other b/tsDMARDs. Pain was measured using visual analogue scale [VAS] (0-100 mm) at 3M. Proportion of pts with ≥30%, ≥50% and ≥70% pain improvement from baseline (BL) and pain VAS ≤10mm, ≤20mm and &gt;20mm was also assessed. Disease activity was measured using clinical disease activity index (CDAI), remission (CDAI ≤2.8) or LDA (CDAI &lt;10). <h3>Results:</h3> 673 pts with available data on disease activity at 3M were included in this analysis. At BL pts in cohort B-TNFi had a shorter disease duration and were more often naive to b/tsDMARDs. 84-97% of pts across the treatment cohorts had at least moderate pain (VAS &gt;20mm) at BL (Table 1). A higher percentage of pts receiving BARI achieved pain improvement in all analysed thresholds than pts in cohort B-OMA at 3M. A higher percentage of pts receiving BARI experienced ≥50% and ≥70% pain improvement versus cohort B-TNFi and a similar percentage achieved ≥30% pain improvement at 3M. Achievement of pain improvement ≥30% was observed in 81% (BARI), 79% (cohort B-TNFi) and 71% (cohort B-OMA) of ≥50% in 67%, 62% and 57% and of ≥70% in 46%, 40% and 41%, respectively (Figure 1). At 3M, the proportion of pts with residual pain (VAS &gt;20) for the treatment groups that achieved Remission/LDA or those that did not achieve Remission/LDA was 38% or 92% for BARI, 44% or 95% for cohort B-TNFi and 45% or 91% for cohort B-OMA, respectively. A higher mean change from baseline in Pain VAS measurements was observed in patients achieving remission/LDA under BARI (-32.6mm) than cohort B-TNFi (-27.3mm) and B-OMA (-28.0mm) at 3M. <h3>Conclusion:</h3> The analyses highlight the association between achievement of pain improvement and that of remission/LDA. Pts treated with BARI besides having longer disease duration and higher number of previous b/tsDMARDs are more likely to achieve pain control than pts receiving TNFi/OMA. Almost half the pts who achieved remission/LDA and who had BARI treatment achieved ≥70% pain relief. <h3>REFERENCES:</h3> [1] Taylor, P.C., et al.
