BTK is involved in both adaptive and innate immune responses and mediates signalling of several immune receptors of relevance to RA and SLE pathogenesis. Targeting BTK is a promising approach therefore for autoimmune disorders with aberrant B cell responses. Evobrutinib is a novel, highly specific, and irreversible BTK inhibitor. In vivo and animal models showed that evobrutinib modulated B cell and innate immune cell activation, was efficacious, and prevented joint damage. The potency of evobru...

UPA monotherapy showed statistically significant improvements in clinical and functional outcomes versus continuing MTX in MTX inadequate-responder patients with RA. Despite its proven effectiveness and safety, many patients are unable to tolerate MTX due to its side-effects. Therapies that can be used without concomitant MTX therefore, have an important place in RA management. In previous studies, UPA has shown efficacy in combination with stable background csDMARDs in RA patients who are DMARD...

TOF 5 mg and 10mg BID demonstrated a consistent safety profile and sustained efficacy for up to 9.5 years in this open-label LTE ORAL Sequel study.TOF 5 mg and 10 mg BID demonstrated consistent safety (as monotherapy and combination therapy) and efficacy within this open-label LTE study of RA patients. As RA requires long-term treatment, it’s important to assess the long-term efficacy and safety of RA therapies to understand the potential lifelong impact on patient health and quality of life.

In a post-hoc analysis, BARI 4 mg showed similar efficacy and safety during placebo-controlled and LTE observation periods regardless of the presence or absence of select comorbidities in RA patients.Patients with RA have a high prevalence of comorbidities. This post-hoc analysis investigated the effect of select comorbidities (depression, osteoporosis, hepatic, cardiovascular or pulmonary disorders) on the efficacy and safety of BARI 4 mg QD in patients with moderate-to-severe active RA and ina...

In this integrated analysis, BARI showed an acceptable safety profile in Japanese patients with up to 3.2 years of exposure. Other than incidences of herpes zoster (HZ), no major differences were noted with BARI safety in Japanese patients with RA, compared to the patients in the integrated database.BARI has previously demonstrated significant clinical efficacy and acceptable safety. Japanese patients who participated in the BARI clinical development programme, were comparable to those from the ...

This study suggests that many bDMARDs and tsDMARDs can be considered equivalent therapeutic alternatives in bDMARD-naïve RA patients, with inadequate response to csDMARDs.In the absence of randomised controlled trials comparing drugs, indirect comparisons and network meta-analysis may provide information to help select an optimal treatment alternative. In this network meta-analysis, 27 randomized controlled trials were analysed to assess the possibility that some drugs on the market may be consi...

RA patients receiving TOF 5 or 10 mg BID plus MTX showed sustained clinical and radiographic treatment effects through months 12-24. The safety profile was consistent with previous TOF studies. The 12-month data from the ORAL Scan study have been previously reported. This report assesses durability of responses, including structural damage progression, and safety with TOF through 24 months. Patients were randomized 4:4:1:1 to receive TOF 5 or 10 mg BID, or PBO advanced to TOF with stable, backgr...

This review shows that changes in lymphocyte subsets were largely within normal reference ranges and were not associated with efficacy or safety end points. BARI is a selective JAK1/JAK2 inhibitor, approved for the treatment of moderate to severe RA. BARI treatment is associated with changes to circulating lymphocyte and lymphocyte subsets, however detailed analyses of these effects, and their relevance to efficacy and safety is lacking. This study investigated the changes in lymphocyte cell sub...

2018 brought a wealth of new data in cytokine signalling and IL-6 that helps inform current clinical practice and brings the promise of new options in the future. There was good data on the use of sub cutaneous tocilizumab as well as strategies in early RA and for methotrexate tapering. For the currently marketed JAK inhibitors, tofacitinib and baricitinib, continuous long-term efficacy and safety data further support its current use and applications. On the development side, the outcomes of the...

Baricitinib (BARI) in combination with MTX and concomitant csDMARDs was shown to be efficacious, regardless of corticosteroid use in RA patients. MTX is prescribed to most RA patients but concomitant csDMARDs and/or corticosteroids can be added. This study assessed the efficacy and safety of BARI in two arms; with/without corticosteroids and; with MTX only/MTX plus csDMARD/csDMARDs only. Baseline characteristics and adverse reactions were also compared. Data were pooled from two phase 3 studies ...
