Patients who were treated with tofacitinib in the RA clinical development programme were more likely to develop herpes zoster than were those who received placebo.Cases of herpes zoster reported by investigators in the Phase 2, Phase 3 and long-term extension studies of tofacitinib were evaluated. Herpes zoster was noted in 5% of tofacitinib-treated patients; only 7% of these cases were serious, no patients with herpes zoster died and only 10% permanently discontinued tofacitinib treatment.The o...

This analysis of exposure to tofacitinib, an oral JAKi for the treatment of RA, for up to 8.5 years allowed estimation of safety events with improved precision versus previous tofacitinib reports. Adverse events were generally stable over time; no new safety signals were observed compared with previous tofacitinib reports.Data were collated into an integrated safety summary of tofacitinib in adult patients with active RA, and included data spanning the tofacitinib clinical programme: from 2 Pha...

Tofacitinib is an oral Janus kinase inhibitor for the treatment of RA. By modulating the signalling of cytokines that are integral to lymphocyte activation, proliferation, and function, tofacitinib may suppress multiple elements of immune response. A systematic literature search including all biologics and tofacitinib procured 66 RCTs and 22 LTEs that were included in a meta-analysis to provide estimated incidence rates, risk ratios, and risk differences of serious infection for each therapy. Es...

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 develop...

Active RA is associated with changes in both high- and low-density lipoprotein cholesterol as well as changes in the level and function of several HDL-associated proteins, yet the pathways and mechanisms involved with systemic inflammation altered lipid metabolism have not been determined. In addition, treatments for active RA are known to modify lipid metabolism, such as increasing circulating cholesterol levels. In the clinical development programme, a proportion of tofacitinib-treated patien...

This article reviews data from animal and phase 2 clinical studies assessing the immunomodulatory effects and pharmacokinetics of CP-690,550 (now known as tofacitinib), as well as its efficacy and safety in patients with rheumatoid arthritis (RA). In two rodent models of arthritis, CP-690,550 produced dose-dependent decreases in signs of disease activity compared with untreated controls, reductions in histologically assessed inflammation and articular cartilage damage, and statistically signific...
