Post hoc analysis of the RA-BEGIN trial finds that, over a one-year period, patients treated with baricitinib (monotherapy or in combination with methotrexate [MTX]) report greater pain relief and a more rapid attainment of clinically meaningful thresholds of pain improvement, than patients who receive MTX monotherapy.Often overlooked, when treating RA solely to a disease activity target, patient-reported pain is common in RA, even in those reaching inflammatory remission. The fact that pain per...

Analysis by Wells, et al. demonstrates long-term efficacy and tolerability of baricitinib 2 mg daily for up to 120 weeks in patients with rheumatoid arthritis.Using data from two completed phase III studies, RA-BEAM (csDMARD-IR patients) and RA-BEACON (TNFi-IR patients), and one ongoing long-term extension study (RA-BEYOND), results demonstrated that the long-term maintenance of clinically relevant treatment goals, including LDA, remission and normative physical function, is achievable with bari...

JAK/STAT 経路: 関節リウマチの疼痛に焦点をあてて

Semin Arthritis Rheum. 2021 Feb;51(1):278-284

Many cytokines associated with RA pathogenesis and pain are affected directly or indirectly by the JAK/STAT pathway, therapeutic targeting may offer promise. Having better understanding of these mechanisms can help clinicians make treatment decisions that optimise the control of inflammation and pain. However, pain in patients with RA is complex and involves multiple driving mechanisms that may differentially occur over time in different people. Although one known constant is that nociceptive ac...

Post hoc analyses from RA-BEAM concluded that BARI 4 mg QD or ADA 40 mg Q2W resulted in improvements in pain, physical function, fatigue and work productivity in patients with RA, independent of the treatment’s impact on inflammation. Among patients achieving remission or LDA, greater improvements in pain and physical function were seen with BARI than with ADA or PBO.Of 1010 patients included in the analysis at Week 24, 168 were in remission, 310 were in remission/LDA and 700 were not in remissi...
