Impact of initial therapy with upadacitinib or adalimumab on achievement of 48-week treatment goals in patients with rheumatoid arthritis: post hoc analysis of SELECT-COMPARE
Rheumatology (Oxford). 2022. Epub ahead of print doi: 10.1093/rheumatology/keac477
Post hoc analysis findings provide the first data evaluating the importance of treatment order with JAKinib vs TNFi as initial therapy, suggesting that a JAKinib first strategy leads to more rapid improvements in treatment outcomes following csDMARD failure.

Achieving pain control in early rheumatoid arthritis with baricitinib monotherapy or in combination with methotrexate versus methotrexate monotherapy
RMD Open. 2022;8(1):e001994 doi: 10.1136/rmdopen-2021-001994
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...Keywords:
Pain Reduction in Rheumatoid Arthritis Patients Who Use Opioids: A Post Hoc Analysis of Phase 3 Trials of Baricitinib
ACR Open Rheumatol. 2021. Epub ahead of print. doi: 10.1002/acr2.11380
This post hoc analysis shows that pain reduction was similar between opioid users and nonusers with baricitinib 2 mg and 4 mg, but not adalimumab.Use of opioids to treat RA-related pain has increased, yet long-term use has been associated with reduced efficacy and safety concerns. In addition, the misuse of opioids has resulted in a public health crisis in the United States and highlights the need for safe, effective nonaddictive alternatives for pain management. As such, Pope, et al. assessed p...Keywords:
Safety of baricitinib for the treatment of rheumatoid arthritis over a median of 4.6 and up to 9.3 years of treatment: final results from long-term extension study and integrated database
Ann Rheum Dis. 2021. Epub ahead of print. doi: 10.1136/annrheumdis-2021-221276.
Analysis of data from the highest level of patient exposure to baricitinib across the spectrum of the RA population demonstrates that baricitinib maintained a similar safety profile to earlier analyses, with no new safety signals identified.Using integrated data from nine randomised controlled trials, Taylor, et al. assessed the safety of baricitinib 2 mg and 4 mg once-daily. Analysis of data from 3770 patients (median 4.6 years, up to 9.3 years) with active RA showed that baricitinib maintained...
Median Time to Pain Improvement and the Impact of Baseline Pain Severity on Pain Response in Patients with Psoriatic Arthritis Treated with Tofacitinib
RMD Open. 2021;7(2):e001609.
Tofacitinib 5 mg twice daily provides clinically meaningful improvements in pain for patients with PsA.Reducing pain is a primary treatment concern for patients with PsA. As such, de Vlam, et al. set out to evaluate the time to pain improvement and the impact of baseline pain severity on pain response in patients with PsA receiving tofacitinib.Using data from the OPAL Broaden and OPAL Beyond trials, they discovered that clinically important improvements in pain were experienced by more patients,...
Efficacy of baricitinib in patients with moderate-to-severe rheumatoid arthritis with 3 years of treatment: results from a long-term study
Rheumatology (Oxford). 2021;60(5):2256-2266.
Baricitinib 4mg may be considered for long-term treatment of early and refractory rheumatoid arthritis following results demonstrating efficacy and tolerability for up to 3 years.Smolen JS, et al. analysed data from two completed 52-week, phase III studies, RA-BEGIN (DMARD-naïve) and RA-BEAM (MTX-IR), and one ongoing long-term extension study (RA-BEYOND) – providing data for 148 weeks in total. Results demonstrated that the long-term maintenance of clinically relevant treatment goals, including ...Keywords:
The JAK/STAT Pathway: A Focus on Pain in Rheumatoid Arthritis
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...
Efficacy of baricitinib in patients with moderate-to-severe rheumatoid arthritis with 3 years of treatment: results from a long-term study
Rheumatology 2020; doi:10.1093/rheumatology/keaa576
Three year follow up data for baricitinib demonstrated efficacy in populations that span the clinical disease continuum in RA, including DMARD-naïve, MTX-IR, csDMARD-IR, and bDMARD-IR and was well tolerated. This study evaluated achievement and maintenance of LDA, remission and physical functioning in patients treated with baricitinib for up to 3 years. Data were analysed from two 52-week, Phase 3 studies (RA-BEAM and RA-BEGIN), and one ongoing long-term extension (RA-BEYOND). Patients completin...
Filgotinib, a JAK1 Inhibitor, Modulates Disease Related Biomarkers in Rheumatoid Arthritis: Results from Two Randomized, Controlled Phase 2b Trials
Rheumatol Ther. 2020 DOI: 10.1007/s40744-019-00192-5
In this study examining the effect of FIL on a panel of biomarkers, FIL down-modulated several key inflammatory mediators of signalling pathways in RA - independent of MTX background therapy. This confirmed the strong network effects of the JAK1 node in autoimmunity, matrix and cartilage degradation, angiogenesis, and leukocyte adhesion and recruitment. Biomarkers key to RA pathophysiology were measured at baseline, Wk4 and Wk12 in FIL 100 mg, FIL 200 mg or PBO treatment groups from two phase 2b...
Effect of Baricitinib and Adalimumab in Reducing Pain and Improving Function in Patients with Rheumatoid Arthritis in Low Disease Activity: Exploratory Analyses from RA-BEAM
J Clin Med. 2019 Sep 5;8(9). pii: E1394
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...
