Genetic analysis of tofacitinib-treated subjects with RA or PsO identified multiple loci associated with increased herpes zoster (HZ) risk.It is well known that HZ risk is elevated in subjects with RA compared with the general population, and that treatment with JAK inhibitors may result in increased risks compared with TNFi and other bDMARD treatments. To this end, Bing, et al. used genome-wide association studies to identify genetic factors associated with an increased risk/faster onset of HZ ...

Fifty-six-week data suggest that upadacitinib could be a favourable long-term treatment option in patients with PsA who are refractory to biologic therapy.As the need for additional therapeutic agents that can effectively control disease activity continues, new data from a 56-week analysis of the oral reversible JAK1 inhibitor, upadacitinib, currently under investigation for the treatment of PsA, shows that efficacy of the drug is maintained over the duration of this study.Mease, et al. explored...

Comparative Analysis of BTK Inhibitors and Mechanisms Underlying Adverse Effects

Understanding of the B-cell receptor signalling pathway led to the identification of a suitable drug target to addresses autoimmunity and inflammation in areas such as MS, RA, pemphigus and SLE. There are currently 22 BTKis in various stages of clinical development. However, AEs such as cardiovascular and bleeding side effects, as well as rash, diarrhoea and infections have been associated with the inhibition of other kinases with a BTKi-binding cysteine in their catalytic domain.Based on clinic...

This integrated Phase III safety analysis of UPA showed that UPA had a similar profile to ADA and MTX for serious infections, malignancies, and thromboembolic events. Patients receiving UPA had increased risk of HZ and creatine phosphokinase elevation versus ADA.This integrated Phase III safety analysis of UPA examined >3500 RA patients and 4000 patient-years of exposure. Data were pooled from 3834 patients in SELECT-NEXT, SELECT-BEYOND, SELECT-MONOTHERAPY, SELECT-COMPARE and SELECT-EARLY studie...

Reports from clinical trials and the US Corrona RA registry showed that serious infection event (SIE) incidence was higher in older versus younger patients with RA receiving 10 mg BID of TOF and ADA, however, SIE risk was similar between age groups with TOF 5 mg BID and ADA.Data were collected from Phase II–IV tofacitinib studies, and the US Corrona RA registry. The clinical data set evaluated patients receiving TOF 5 and 10 mg BID versus TNFi (ADA/ETN) in RA patients aged ≥50 years. The EMA rec...

Baricitinib, an oral selective JAK1 and JAK2 inhibitor,8 demonstrated significant clinical efficacy in phase 3 RA trials. Pooled data from these trials, including a long-term extension (LTE), inform the safety profile for baricitinib, mainly to evaluate the incidence of infection in patients with active rheumatoid arthritis (RA), with a focus on serious infection, tuberculosis (TB), herpes zoster (HZ) and opportunistic infection (OI). The data collected were from eight double-blind randomised tr...

This 24-week update from the baricitinib RA-BEYOND LTE study follows patients previously treated in the pivotal study RA-BEGIN. It demonstrates the maintained safety and efficacy of baricitinib monotherapy, and the effects of concurrent MTX treatment on response rates and patient reported outcomes. Previous P3 study RA-BEGIN demonstrated the superior efficacy of 4mg baricitinib compared to MTX monotherapy up to 52 weeks, with no major safety events being identified. At the end of the trial, pati...

This review investigates the potential implications of COVID-19 on the field of rheumatology. Common pathways in COVID-19 and RA have provided rationale for the trial of DMARD therapies in treatment of severe COVID-19 infections. Safety considerations of RA patients undergoing immunomodulatory treatments are reviewed. Recommendations suggest that RA patients should continue DMARD treatment, whereas glucocorticoid use could be deleterious in COVID-19 infection and should be considered carefully, ...

RA is a chronic, life-long disease requiring long-term treatment. As such, it is important to understand the long-term safety profile of DMARDs. In this analysis, baricitinib maintained a stable safety profile during long-term exposure. This baricitinib safety analysis included integrated data from nine Phase 3, 2, and 1b clinical trials, and one long-term extension, with data up to 360 weeks. 3700 patients were included, with maximum follow-up of almost 7 years – representing an additional 3,54...

This study conducted mainly in Chinese patients with RA, and an inadequate response to MTX, showed that baricitinib 4mg was associated with significant improvements and consistent with the findings from previous clinical trials.The efficacy and safety of baricitinib have been assessed in several clinical trials, predominantly in Caucasian populations. However, evidence on the efficacy and safety of baricitinib in Chinese patients is limited, with only one of the main clinical trial program studi...
