COVID-19 revisiting inflammatory pathways of arthritis

Nat Rev Rheumatol 2020 doi.org/10.1038/s41584-020-0451-z

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, ...

Safety and Efficacy of Tofacitinib in Patients with Active Psoriatic Arthritis: Interim Analysis of OPAL Balance, an Open-Label, Long-Term Extension Study

Rheumatol Ther 2020 doi.org/10.1007/s40744-020-00209-4

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...

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...

Fenebrutinib Versus Placebo or Adalimumab in Rheumatoid Arthritis: A Randomized, Double-Blind, Phase II Trial (ANDES Study)

Arthritis Rheumatol. 2020 Sep; 72(9): 1435–1446.

In this randomised phase II trial with MTX treatment-refractory RA patients, greater efficacy was observed with fenebrutinib 150 mg once daily or 200 mg twice daily compared to placebo, while response rates were numerically similar to those observed with adalimumab. BTK inhibitors have demonstrated clinical efficacy in B cell malignancies and multiple sclerosis, although there is limited clinical evidence of its efficacy in RA. Fenebrutinib (FEN) an orally active and selective non-covalent inhib...

Evaluation of Hepatitis B Virus in Clinical Trials of Baricitinib in Rheumatoid Arthritis

RMD Open 2020;6:e001095

Although hepatitis B virus (HBV) reactivation was seen in patients with RA treated with DMARDs, including BARI, who had serology suggestive of prior infection, reactivation was transient even with continued BARI treatment and did not account for any clinically relevant AEs.Reactivation of HBV replication is a recognised complication in patients receiving biologic agents for RA, such as DMARDs. Limited data exist on prevalence of occult infection and the incidence of reactivation in RA patients t...

An Integrated Analysis of the Safety of Tofacitinib in Psoriatic Arthritis Across Phase III and Long Term Extension Studies with Comparison to Real World Observational Data

Drug Saf. 2020;43:379-392

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...
