Itacitinib is an orally active JAK inhibitor and effectively delayed disease onset, reduced symptom severity, and accelerated recovery of inflammatory diseases in mouse models. Covington M et al demonstrated itacitinib’s high selectivity for JAK 1, its inhibition on IL-2 induced T cell proliferation and JAK/STAT signalling, its ability to also inhibit of the JAK/STAT pathway in response to IL-6 stimulation, and its effect on rat adjuvant induced arthritis model. The study used recombinant enzym...

This study highlights the importance of accounting for known risk factors of RA-ILD in clinical practice. Interstitial lung disease (ILD) is an extra-articular manifestation of RA. The post-hoc investigated incidence rates of ILD in patients with RA, receiving tofacitinib 5 or 10 mg twice daily, and identified potential risk factors for ILD. This post-hoc analysis comprised a pooled analysis of patients receiving tofacitinib 5 or 10 mg twice daily or placebo from 21 Phase 1-4, and 2 long-term ex...

Upadacitinib monotherapy demonstrated superior clinical, radiographic, and patient-reported outcomes versus methotrexate in methotrexate-naïve RA patients.This 48-week double-blind active comparator study investigated upadacitinib monotherapy in patients with early RA, who were either methotrexate-naïve, or who had very limited exposure. 947 patients were randomised to once-daily upadacitinib 15 or 30 mg, or weekly methotrexate. Unusually, there were two separate primary endpoints, selected for ...

This SLR reviewed data on pharmacological treatment of PsA. Findings informed the 2019 EULAR taskforce when updating recommendations for PsA management. Overall, no new safety signals were reported. Encouragingly, LTEs of JAKi did not report any venous thromboembolic events or PEs. Efficacy was demonstrated for a range of bDMARD and tsDMARD therapies in various disease domains. Efficacy varied between PsA manifestations and between therapies. Observational data demonstrated efficacy when switchi...

This 3-year, open-label, LTE study follows PsA patients previously treated in pivotal studies OPAL Broaden and OPAL Beyond. It demonstrates maintained safety and efficacy of tofacitinib up to 36 and 30 months, respectively. No new safety concerns are highlighted. Previous P3 studies, OPAL Broaden and OPAL Beyond, demonstrated safety and efficacy of 5mg and 10mg tofacitinib BID in PsA. These patients rolled over to OPAL Balance for a period of 36 months. 686 participants were used in this interim...

This study aimed to characterize temporary interruptions of baricitinib and describe their impact on efficacy and safety. Brief interruptions during phase 3 baricitinib trials were associated with minor increases in symptoms which were resolved following treatment. In life-long, chronic conditions such as RA, interruption of therapy is common for various reasons, such as side effects, non-compliance, or because a patient requires surgery. Concerns have been raised that these treatment breaks cou...

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...

Patients with psoriatic arthritis (PsA) had similar safety profile with TOF to that of other systemic therapies in real-world settings, except for the known risk of HZ. Treatment recommendations from EULAR and GRAPPA for patients with PsA vary according to adverse prognostic risk factors, disease manifestations and responsiveness to prior treatment. Safety concerns for most PsA therapies include gastrointestinal AEs, hepatotoxicity, opportunistic infections (OIs) including TB, and SIEs. This stu...

Relative Efficacy and Safety of Tofacitinib, Baricitinib, Upadacitinib, and Filgotinib in Comparison to Adalimumab in Patients with Active Rheumatoid Arthritis

This Bayesian network meta-analysis, comparing the relative efficacy and safety of JAK inhibitors, determined BARI 4mg + MTX and UPA 15mg + MTX were the most effective. The analysis included 5451 patients with an inadequate response to MTX and active RA, from four RCTs. Relative effects were converted into a probability allowing each treatment to be ranked. BARI and UPA had significantly higher ACR20 response rates than ADA 40mg + MTX whilst TOF 5mg and FIL 200mg had comparable ACR20 response ra...

Broad and focused studies are required to have an insight of safety for small molecules, such as JAK inhibitors in the case of accidental exposure before or during pregnancy.This case study’s objective describes a case report of a 43-year-old woman affected by RA who became pregnant during BARI treatment. She has had two previous pregnancies at term without complications. After failure of bDMARDs due to loss of efficacy and adverse drug reactions, the patient was started on BARI when it became a...
