Infections in Baricitinib Clinical Trials for Patients with Active Rheumatoid Arthritis

Annals of the Rheumatic Diseases, May 2020

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...

Incidence Rates of Interstitial Lung Disease Events in Tofacitinib-Treated Rheumatoid Arthritis Patients

Journal of Clinical Rheumatology, Aug 2020 doi: 10.1097/RHU.0000000000001552.

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...

Efficacy and Safety of Long-Term Baricitinib With and Without Methotrexate for the Treatment of Rheumatoid Arthritis: Experience With Baricitinib Monotherapy Continuation or After Switching From Methotrexate Monotherapy or Baricitinib Plus Methotrexate.

Arthritis Care Res (Hoboken) 2020;72(8):1112-1121

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...

Efficacy and Safety of Upadacitinib Monotherapy in Methotrexate-naïve Patients with Moderately to Severely Active Rheumatoid Arthritis (SELECT-EARLY): A Randomized, Double-blind, Active-comparator, Multi-center, Multi-country Trial

Arthritis Rheumatol 2020

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 ...

Safety of synthetic and biological DMARDs: a systematic literature review informing the 2019 update of the EULAR recommendations for the management of rheumatoid arthritis

Annals of the Rheumatic Diseases 2020;79:760-770

This SLR informed the 2019 EULAR taskforce updating recommendations for RA management. Overall, no new safety signals were reported. The known safety profile of bDMARDs was confirmed and extended to tsDMARDS. IL-6i associated lower intestinal perforation has been further confirmed, while VTE and PE concerns in JAKi treatment need further evaluation.Previous updates for the EULAR recommendations on RA pharmacological management were conducted in 2016. In this SLR safety of csDMARDs, tsDMARDs, and...

Drug retention of 7 biologics and tofacitinib in biologics-naïve and biologics-switched patients with rheumatoid arthritis: the ANSWER cohort study

Arthritis Res Ther 2020;22:142

This paper is based upon a long-term cohort study, namely the ANSWER cohort, an observational multi-centre registry of RA patients in the Kansai district of Japan. Analyses demonstrate a difference in observed drug retention between bDMARDs-naïve and bDMARDs-switched patients. 7 bDMARD treatments were compared in patients with no prior exposure to biologics, with abatacept showing the greatest retention rate. In patients that had switched between these same bDMARDs or to tofacitinib throughout t...

Comparative effectiveness of antitumour necrosis factor agents, biologics with an alternative mode of action and tofacitinib in an observational cohort of patients with rheumatoid arthritis in Switzerland

RMD Open 2020;6:e001174 doi:10.1136/rmdopen-2020-001174

This nested cohort study found that, in Switzerland, there was a generally limited overall drug maintenance for b/tsDMARD options in RA. Using data from SCQM-RA – a prospective longitudinal registry, overall maintenance (drug survival) was calculated for TNFi, bDMARD-OMA or JAKi in patients with RA.After adjusting for potential confounding factors, there was a higher hazard of drug discontinuation with TNFi compared with tofacitinib; no significant difference was observed between non-TNF bDMARDs...

Temporary Interruption of Baricitinib: Characterization of Interruptions and Effect on Clinical Outcomes in Patients With Rheumatoid Arthritis

Arth Res Ther 2020;22:115 doi.org/10.1186/s13075-020-02199-8

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...

Safety Profile of Baricitinib For the Treatment of Rheumatoid Arthritis Over a Median of 3 Years of Treatment: An Updated Integrated Safety Analysis

Lancet Rheumatol 2020;2:e347–57

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...

Baricitinib In Patients with Rheumatoid Arthritis With Inadequate Response to Methotrexate: Results From A Phase 3 Study

Clin Exp Rheumatol . Jul-Aug 2020;38(4):732-741. Epub 2020 May 20.

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...
