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...

Study shows that conversions from FACIT-F to PROMIS Fatigue are feasible and applicable for RA clinical trials.The Functional Assessment of Chronic Illness Therapy–Fatigue (FACIT-F), developed for use in cancer patients, has been validated for measuring fatigue in RA, and is often the tool used in European clinical trials; with 10 out of its 13 items being relevant for patients with RA. The Patient-Reported Outcomes Measurement Information System (PROMIS), developed and calibrated in the United ...

The first study to combine in vitro inhibition of cytokine responses in whole blood with clinical pharmacokinetics of individual JAKinibs to model daily cytokine-mediated pharmacodynamic profiles in healthy individuals and patients with RA, has demonstrated that JAKinib potencies depended on cytokine stimulus, pSTAT readout and cell type.Traves and colleagues have observed that JAKinibs have unique, differential effects on specific cytokine signalling pathways, dependent on cytokine stimulus, ST...

MRI studies have shown that BARI reduces joint inflammation and damage in patients with moderate-to-severe active RA. This review summarises the effects of BARI on structural joint damage progression and the mechanisms underlying these effects, using MRI data from across the clinical trial program. Early preclinical animal models showed a significant reduction in joint inflammation, ankle width, and bone resorption. Efficacy and safety of BARI have been confirmed in an extensive programme, inclu...

2020 unfolded apace, dominated by COVID-19 - we have all had to adapt in our practice and in our knowledge base. Amid this there have continued to be a constant flow of publications and science in cytokine signaling, and as in previous years as we come the end of 2020, I will highlight some of the notable papers of the year. You can find the most notable papers, as selected by CSF Steering Committee Chair Professor Iain McInnes, with links to their respective detailed summaries below:

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...

BARI demonstrated to be a safe immune modulator that reduces the concentrations biomarkers of lung fibrosis and inflammation in RA patients, including a subgroup with interstitial lung involvement. Professor Alessandro and colleagues analysed the effects of baricitinib in a population of RA and RA-ILD patients in a real-life setting, describing any changes in lung function parameters, serum inflammatory biomarkers and fibrotic biomarkers after 6 months of treatment. Fifteen patients were recruit...

BARI may potentially interrupt the passage of SARS-CoV-2 into the target cells by binding to AAK1 and GAK, which are regulators of the ACE2 receptor regulator identified for its uptake, and could also treat cytokine storm through suppression JAK1/JAK2. Professor Zhang and et al reviewed BARI, as a potential drug to prevent SARS-COV-2 from entering target cells. They also evaluated BARI’s ability to control COVID-19 induced cytokine storm. As a cell surface protein, ACE2 is involved in receptor-m...

Amrhein et al examined the different uptake and expulsion mechanisms of BARI and TOF in cellular assays. Different cellular uptake mechanism for BARI and TOF was observed and showed that BARI’s transport was not dependent on organic cation transporters. Results indicated TOF was exported from RASF in a MATE-1 dependent way. TOF might be exported from healthy cells, thereby not inhibiting JAK pathway in these cellsThe interaction of BARI and TOF with OCTs was investigated using quenching experime...

Autoantibodies associated with the onset of RA have gained attention in recent years as prognostic biomarkers. Though not used diagnostically, anti-CarbV (carbamylated vimentin) and anti-MCV (vimentin modified by citrullination) baseline titers are being investigated as predictors of treatment response. In this post-hoc analysis of data from the RA-BEGIN cohort of active RA patients, López-Romero and colleagues consider the potential predictive values of baseline anti-CarbV and anti-MCV titers r...
