The JAK/STAT Pathway: A Focus on Pain in Rheumatoid Arthritis

Semin Arthritis Rheum. 2021 Feb;51(1):278-284

Many cytokines associated with RA pathogenesis and pain are affected directly or indirectly by the JAK/STAT pathway, therapeutic targeting may offer promise. Having better understanding of these mechanisms can help clinicians make treatment decisions that optimise the control of inflammation and pain. However, pain in patients with RA is complex and involves multiple driving mechanisms that may differentially occur over time in different people. Although one known constant is that nociceptive ac...

Baricitinib Inhibits Structural Joint Damage Progression in Patients with Rheumatoid Arthritis – A Comprehensive Review

Arthritis Res Ther 2021;23(1):3.

MRI studies have shown that BARI reduces joint inflammation and damage in patients with moderate-to-severe active RA. This review summarises the effects of BARI on structural joint damage progression and the mechanisms underlying these effects, using MRI data from across the clinical trial program. Early preclinical animal models showed a significant reduction in joint inflammation, ankle width, and bone resorption. Efficacy and safety of BARI have been confirmed in an extensive programme, inclu...

Filgotinib Versus Placebo or Adalimumab in Patients with Rheumatoid Arthritis and Inadequate Response to Methotrexate: A Phase III Randomised Clinical Trial

Ann Rheum Dis. 2021 Jan 27:annrheumdis-2020-219214

Filgotinib improved RA signs and symptoms, physical function, and inhibited radiographic progression. FIL 200mg plus MTX, but not FIL 100mg plus MTX showed non-inferiority to ADA plus MTX, based on DAS28(CRP) low disease activity. FIL was also well tolerated in RA patients with inadequate response to MTX.This 52-week, phase 3 randomised clinical trial (FINCH 1) evaluated the efficacy and safety of FIL in patients with RA randomised to FIL 200 or 100mg, ADA 40mg, or placebo, all with background M...

Bimekizumab efficacy and safety in moderate to severe plaque psoriasis (BE READY): a multicentre, double-blind, placebo-controlled, randomised withdrawal Phase 3 trial

Lancet 2021;397:475–86 doi: 10.1016/S0140-6736(21)00126-4

Bimekizumab therapy was associated with a rapid and sustained improvement in PASI response and IGA score in patients with moderate to severe plaque psoriasis. Dual inhibition of IL-17A/F with bimekizumab can affect a more durable response in PsO patients than sole IL-17A inhibition. Gordon et al. compared the safety and efficacy of two different maintenance dosing schedules, in addition to the effects of treatment withdrawal in the 52-week BE READY trial.

Bimekizumab versus ustekinumab for the treatment of moderate to severe plaque psoriasis (BE VIVID): Efficacy and safety from a 52-week, multicentre, double-blind, active comparator and placebo controlled Phase 3 trial

Lancet 2021;397:487–98. doi: 10.1016/S0140-6736(21)00125-2

Bimekizumab was more efficacious than ustekinumab and placebo in the treatment of moderate to severe plaque psoriasis. Previous bimekizumab Phase 2 clinical studies have shown both rapid and durable clinical improvements in skin clearance, as well as a safety profile in line with expectations from this MoA. This study aimed to evaluate the efficacy and safety of bimekizumab in moderate to severe plaque PsO over 1 year compared with both placebo and ustekinumab.

Upadacitinib for psoriatic arthritis refractory to biologics: SELECT-PsA 2

Annals of the rheumatic diseases. 2021 Mar 1;80(3):312-20.

In this trial of patients with active PsA who had inadequate response or intolerance to at least one biologic DMARD, upadacitinib 15 mg and 30 mg was more effective than placebo over 24 weeks in improving signs and symptoms of PsA. Despite the availability of bDMARDs in PsA, only a small proportion of patients achieve the recommended target of minimal disease activity; as such, additional treatment options are needed. Upadacitinib is under evaluation for PsA. This paper reports the 24-week data ...

Tofacitinib in psoriatic arthritis patients: skin signs and symptoms and health-related quality of life from two randomized Phase 3 studies

J Eur Acad Dermatol Venereol 2020;34:2809–2820.

Considering the multi-domain nature of PsA, effective treatments must demonstrate efficacy across a range of clinical and patient-reported outcomes. Dermatologic symptoms often precede rheumatic manifestations in people with PsA, typically by 10 years. Tofacitinib demonstrated significant improvements across a range of outcomes including burdensome dermatologic symptoms. This post hoc analysis included data from two double-blind, Phase 3 studies in patients with active PsA and an inadequate resp...

EULAR Definition of Difficult-to-Treat Rheumatoid Arthritis

Ann Rheum Dis 2021;80:31–35.

A significant proportion of people with RA remain symptomatic despite treatment according to current management recommendations. Different terms have traditionally been used to describe this subpopulation, including severe, refractory, resistant to multiple drugs or treatments, established and difficult-to-treat. A recent survey indicated that – in addition to new drugs – new management approaches are needed for optimal treatment in these patients.A EULAR Task Force agreed the uniform terminolog...

Comparative effectiveness of first-line tumour necrosis factor inhibitor versus non-tumour necrosis factor inhibitor biologics and targeted synthetic agents in patients with rheumatoid arthritis: results from a large US registry study

Ann Rheum Dis 2021;80:96–102.

RA treatment guidelines recommend a treat-to-target approach guided by disease stage and treatment history, yet the optimal sequence of different treatment modalities has not been established. Data from Corrona – were used to evaluate the comparative effectiveness of TNFi versus non-TNFi bDMARDs and tsDMARDs as first-line treatment following csDMARD failure. Results support RA guidelines recommending individualised care based on clinical judgement and consideration of patient preference.The stud...
