JAKinibs have been linked with an increased risk of HZ in patients with RA. To this end, Winthrop, et al. evaluated data from six Phase III clinical trials to determine the incidence of HZ in the upadacitinib (UPA)-treated patients with RA and identify potential risk factors for the development of HZ in these patients. Analysis of data provides further support for the need for continued vigilance and monitoring for signs of herpes zoster (HZ) in patients receiving UPA, particularly in Asian popu...

Which Patient-reported Outcomes do Rheumatology Patients Find Important to Track Digitally? A Real-world Longitudinal Study in Arthritis Power

Nowell WB, Gavigan K, Kannowski CL, Cai Z, Hunter T, Venkatachalam S, Birt J, Workman J, Curtis JR.
Arthritis Res Ther. 2021;23(1):53.

Fatigue, physical function, pain, and morning joint stiffness are the most important PROs to track, according to the rheumatology patients who experience these symptoms. Increasingly used, alongside clinical measures, to track symptoms and assess disease activity over time, patient-reported outcomes (PROs) are also important indicators of quality of life and treatment effectiveness. To enable us to better understand which PROs patients with rheumatic and musculoskeletal disease consider most im...

Diminished cytokine-induced Jak/STAT signaling is associated with rheumatoid arthritis and disease activity

Ptacek J, Hawtin RE, Sun D, Louie B, Evensen E, Mittleman BB, Cesano A, Cavet G, Bingham CO III, Cofield SS, Curtis JR, Danila MI, Raman C, Furie RA, Genovese MC, et al.
PLoS ONE 2021;16(1):e0244187

This analysis provides evidence that immune cell signalling pathways are important in RA. There were consistent differences between RA patients and healthy controls in IFNα, IL-6, IL-10 and GM-CSF+ IL-2 induced JAK/STAT signalling in multiple immune cell subsets. We know that RA is characterised by dysregulation of immune responses, but the exact cause is unknown. Recently, single-cell transcriptomics and mass cytometry confirmed the critical role of activated immune cells and fibroblasts...

Concerns surrounding increased rates of PE and cardiovascular associated deaths has led to black box warnings when prescribing JAK inhibitors. As such, ongoing investigations regarding cardiovascular and VTE event risks in JAK inhibitor therapies, both clinical and real-world, are vital. Mease and colleagues consider data from clinical tofacitinib development programmes, and the ongoing real-data study A3921133. Conclusions from data analysis state that those with pre-existing cardiovascular and...

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

Burmester GR, Curtis JR, Yun H, FitzGerald O, Winthrop KL, Azevedo VF, Rigby WFC, Kanik KS, Wang C, Biswas P, Jones T, Palmetto N, Hendrikx T, Menon S, Rojo R.
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 s...

Tofacitinib Kullanıcılarında Herpes Zoster Riski Glukokortikoidlerle Artmıştır Ancak Methotreksat ile Değil

Curtis JR, Xie F, Yang S, Bernatsky S, Chen L, Yun H, Winthrop K.
Arthritis Care Res 2018 DOI 10.1002/acr.23769

The rate of Herpes Zoster (HZ) in tofacitinib (TOF) users with concomitant glucocorticoids (GC) was approximately double that of other TOF combination therapies. TOF is an effective treatment for RA. Increased HZ risk has been observed with the use of JAK inhibitors, whereas the HZ risk with biologics and targeted RA therapies are comparable. This study evaluated the HZ risk in TOF users according to concomitant GC, MTX, both, or neither. MarketScan and Medicare data were used to identify 8030 ...

Effectiveness and Safety of Tofacitinib in Rheumatoid Arthritis: a Cohort Study

Machado MAÁ, Moura CS, Guerra SF, Curtis JR, Abrahamowicz M, Bernatsky S.
Arthritis Res Ther 2018; 20(1):60 doi: 10.1186/s13075-018-1539-6

A retrospective cohort study of tofacitinib (TOF) revealed that patients previously treated with methotrexate who initiated TOF, presented no differences in hospitalised infections or effectiveness, compared with non-TNF biologics. Currently, TOF is recommended in ACR and EULAR guidelines as an alternative to biologics after first-line cDMARD therapy. Previous indirect comparisons have shown that patients with RA who experience cDMARD failure show similar efficacy when given TNFis, abatacept, ...

Tofasitinib Romatoid Artrit Klinik Programında Melanom Dışı Deri Kanserlerinin Analizi

Curtis JR, Lee EB, Martin G, Mariette X, Terry TT, Chen Y, Geier J, Andrews J, Kaur M, Fan H, Nduaka CI.
Clin Exp Rheumatol 2017;35:614–22

Because non-melanoma skin cancer (NMSC) is one of the most common malignancies associated with RA immunomodulatory therapies, this analysis looked to determine the rate of NMSC incidence per 100 patient-years in patients with RA receiving TOF in the clinical trial programme. The Phase 1, 2, and 3 IRs (combined) for both TOF 5- and 10 mg were low and comparable to those of adalimumab, MTX and placebo, IRs remained stable over time. TOF doses used in the 2 Phase 1; 8 Phase 2; and 6 Phase 3 studi...

J Med Econ 2017;20:464–73

This retrospective study looked at claims-based datasets to establish whether it is preferable to switch to another TNF inhibitor (TNFi) or to a therapy with a different mechanism of action (MOA) when RA treatment failure occurs with an initial TNFi, due to inadequate response or lack of tolerability. Administrative claims data from a large US database were used to compare treatment patterns, treatment effectiveness (based on fulfillment of six criteria) and costs in in the 12 months after RA p...

Interstitial lung disease (ILD) is a common extra-articular condition for RA patients. This retrospective cohort study of health insurance databases investigates the ILD incidence and exacerbation between ABA, TCZ, RTX, and anti-TNFα agents in adult RA patients with prior biologic therapy. Two definitions of ILD were used: one specific, one sensitive; descriptive results were produced for both. In patients with no history of ILD, the overall incidence rate of ILD ranged from 1.8% to 6.4%...

The developments of certain malignancies associated with chronic inflammatory diseases such as RA is known to occur to a greater extent than that of the general population. It is also know that certain RA treatments can affect malignancy rates. As such, newer immunomodulatory agents, such as the JAK inhibitor tofacitinib, are closely monitored for safety events of special interest, including malignancies. This paper analyses pooled malignancy data from the tofacitinib RA clinical development...
