Rheumatology (Oxford). 2021;60(4):1708-1716.

Long-term evaluation of tofacitinib has found limited progression of structural damage in patients with RA treated with tofacitinib for up to 5 years. Similar results were also observed for patients receiving tofacitinib monotherapy or combination therapy for up to 3 years. It is well known that inflammation in RA leads to structural damage over time, and therapies such as DMARDS have the ability to reduce inflammation whilst inhibiting the progression of structural damage. In this study, van...

Ann Rheum Dis. 2020 10.1136/annrheumdis-2019-216566

The results of ORAL Sequel suggest that the live zoster vaccine (LZV) may not provide adequate long-term protection in patients with RA receiving TOF. This LTE study enrolled 100 patients with RA, 14 weeks post LZV vaccination. Patients received either TOF 5 mg BID, or TOF 10 mg BID in addition to any background csDMARDs. Incidence rates and 95% CIs for HZ post-vaccination were calculated based on time to first event. Short-term varicella zoster vaccine (VZV) specific immunity was evaluated a...

Evaluation of the Short-, Mid-, and Long-term Effects of Tofacitinib on Lymphocytes in Patients with Rheumatoid Arthritis

van Vollenhoven R, Lee EB, Strengholt S, Mojcik C, Valdez H, Krishnaswami S, Biswas P, Lazariciu I, Hazra A, Clark JD, Hodge J, Wang L, Choy E.
Arthritis Rheumatol 2018 DOI: 10. 1002/art.40780

Tofacitinib (TOF) treatment is associated with short-term transient increases in absolute lymphocyte counts (ALC), followed by a gradual decline to reach steady state by ~48 months. Changes in both ALC and lymphocyte subset counts (LSC) were reversible upon TOF discontinuation. Low ALC but not LSC were associated with an increased risk of serious infective episodes (SIEs) and herpes zoster (HZ). This data supported the treatment recommendations on ALC counts for starting and continuing therapy w...

Romatoid Artritli Hastalarda Metotreksat veya Glukokortikoid Başlanmasının yada Kesilmesinin Tofacitinib Etkinliği Üzerine Etkisi: Bir Post Hoc Analiz

Fleischmann R, Wollenhaupt J, Cohen S, Wang L, Fan H, Bandi V, Andrews J, Takiya L, Bananis E, Weinblatt ME.
Rheumatol Ther 2018 Jun; 5(1):203–14. DOI: 10.1007/s40744-018-0093-7

Methotrexate (MTX) or Glucocorticoid (GC) discontinuation has little effect on CDAI response in patients given tofacitinib (TOF) for up to 3 years. Patients receiving TOF who showed initial improvements benefitted from initiation of MTX or GCs. Concomitant treatments such as MTX or GC are commonly used in combination with RA therapies to improve or accelerate clinical responses. However, their use is associated with many adverse events so clinicians aim to use them for a minimal duration. This ...

This Chinese sub-population of patients with RA from ORAL Sync reported significant improvements in patient-reported outcomes (PROs), which were maintained up to 12 months from tofacitinib (TOF) treatment initiation. ORAL Sync was a randomised, Phase 3 study investigating TOF therapy in combination with csDMARDs in patients with active RA who had previously had an inadequate response to csDMARDs. To date, this is the only Phase 3 study of TOF in patients from China with RA. This analysis inclu...

Arthritis Rheumatol 2017;69(10):1960–68

The results of this analysis of patients with herpes zoster (HZ) within the global tofacitinib (TOF) RA programme suggest that there is likely to be a greater HZ risk in patients receiving TOF and glucocorticoids compared with patients receiving TOF monotherapy. The global TOF RA development programme comprised 2 Phase 1, 9 Phase 2, 6 Phase 3 and 2 long-term extension studies. These studies included 6192 patients; data were reviewed to identify cases of HZ. Crude incidence rates of number of pa...

This retrospective, observational study used a real-world US clinical database to demonstrate greater effectiveness of switching to a therapy with an alternative mechanism of action (MOA) vs cycling between TNF inhibitors (TNFis) in patients in which TNFi therapy has failed. Between 1 April 2010 and 31 March 2015, a total of 613 of the observed patients failed a TNFi therapy and then either cycled to another TNFi therapy (54.2%) or switched to a therapy with an alternative MOA (45.8%). The most...

Kremer JM, Emery P, Camp HS, Friedman A, Wang L, Othman AA, Khan N, Pangan AL, Jungerwirth S and Keystone EC.
Arthritis Rheumatol 2016;68:2867–77

The summary and accompanying slide deck have been developed in conjunction with the Genovese et al. study (Study 1) which examined ABT-494 in MTX-IR patients in order to compare and contrast the data. In these two Phase 2b studies, ABT-494 (a novel selective JAK-1 inhibitor) was shown to be effective in patients with active RA who were non-responders to MTX or at least one TNF inhibitor. Patients with active RA who had an inadequate response to MTX (study 1) or were refractory to or intoleran...

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...
