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 pati...

Analysis of 19 studies involving the use of tofacitinib to treat RA showed that lymphoma incidence rate and type were consistent with expectations in the RA population as a whole, and did not increase with tofacitinib exposure time.Previous research has suggested that there is a link between the likelihood of developing malignant tumours and RA. Previously, it has been unclear whether the increased rates seen are due to the use of immunomodulatory therapies, such as tofacitinib, which are used a...

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 c...

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 pat...

Evidence is presented that treatment with sarilumab demonstrates patient-reported benefits in TNF-IR patients with moderate to severe RA. These improvements complement the clinical efficacy previously reported for sarilumab, and are consistent with those seen in the MOBILITY trial (MTX-IR patients)1, yet in a more difficult-to-treat population.Data were analysed from the 24-week Phase 3 TARGET randomised controlled trial in adult patients with active RA and previous inadequate response or intole...

Data were examined to compare patient characteristics, treatment patterns and costs in patients with RA receiving tofacitinib (TOF) or common bDMARDs (adalimumab [ADA], etanercept (ETN) or abatacept [ABA]) who had previously received a single bDMARD.This study analyses real-world data from two US claims databases between November 2012 and October 2014. Data were collected from a total of 1252 patients in the Truven Marketscan Commercial and Medicare Supplemental databases. Pre-index (12-months b...
