Efectividad y Seguridad de Tofacitinib en Artritis Reumatoide: Un Estudio de Cohorte

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, to...

Experiencia Mundial de Vigilancia Después de la Comercialización de Tofacitinib en Artritis Reumatoide a lo largo de 3 Años

Rheumatol Ther 2018 Jun; 5(1):283–91

This real-world analysis of tofacitinib (TOF) revealed that AEs reported by patients with RA from 2012 to 2015 were consistent with the known safety profile of TOF – no new safety risks were identified.As of August 2017, it is estimated that more than 102 000 patients worldwide have received TOF, but TOF safety has not been evaluated in patients with real-world experience. This analysis addressed this – by evaluating the safety of TOF from post-marketing surveillance (PMS) reports from patients ...

Niveles de transaminasas y Eventos Hepáticos Durante Tratamiento con Tocilizumab: Análisis Conjunta de Datos de Seguridad en Ensayos Clínicos de Largo Plazo en Artritis Reumatoide.

Arthritis Rheumatol. 2017 Sep;69(9):1751-1761. doi: 10.1002/art.40176

In this pooled analysis investigating liver enzyme abnormalities and hepatic adverse events (AEs) during long-term tocilizumab (TCZ) treatment for RA in clinical trials, although transaminase elevations were frequent, rates of hepatic serious AEs remained low. Data were pooled from patients who received ≥1 dose of IV TCZ with or without DMARDs in Phase 3 or 4 clinical trials, long-term extensions, and a pharmacology study.A total of 4171 patients were included in the all-exposure population with...

Treatment Persistence and Clinical Outcomes of Tumor Necrosis Factor Inhibitor Cycling or Switching to a New Mechanism of Action Therapy: Real-world Observational Study of Rheumatoid Arthritis Patients in the United States with Prior Tumor Necrosis Factor Inhibitor Therapy

Adv Ther. 2017 Aug;34(8):1936-1952. doi: 10.1007/s12325-017-0578-8

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...

Tratamiento de la Artritis Reumatoide con Antagonista del Factor de Necrosis Tumoral o Tocilizumab como el Primer Biológico en un Estudio Comparativo Observacional

Arthritis Care Res (Hoboken). 2017 Oct;69(10):1484-1494. doi: 10.1002/acr.23303

To date, the comparative efficacy of tocilizumab and TNFi for patients with RA has only been investigated in a single head-to-head trial and network meta-analyses. This study, ACT-iON, is the first prospective, large-scale, global, multicentre, comparative effectiveness study comparing initiation of intravenous tocilizumab with initiation of a TNFi in patients with RA as the first-line biologic treatment after inadequate response to csDMARDs. Patients were observed in a real-world, clinical pra...

Discontinuation of Tofacitinib after achieving Low Disease Activity in Patients with Rheumatoid Arthritis: a Multicentere, Observational Study

Rheumatology. Doi 10.1093/rheumatology/kex068

This study showed that in patients who achieved low disease activity (LDA), it is possible to discontinue tofacitinib without flare in approximately one-third of patients. Patients from the tofacitinib Phase 3 programme and long-term extension study were enroled. Discontinuation was based on physician-patient decision making with informed consent. The primary endpoint was the proportion of patients who remained tofacitinib free at post-treatment Week 52. Of 64 patients treated with tofacitinib w...

Evaluation of Real-World Experience with Tofacitinib Compared with Adalimumab, Etanercept, and Abatacept in RA Patients with 1 Previous Biologic DMARD: Data from a U.S. Administrative Claims Database

J Manag Care Spec Pharm. 2016 Dec;22(12):1457-1471.

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...

Risk for Gastrointestinal Perforation Among Rheumatoid Arthritis Patients Receiving Tofacitinib, Tocilizumab, or Other Biologics

Arthritis Rheumatol. 2016 May 17. DOI 10.1002/art.39761 [Epub ahead of print]

Historically, patients with RA have suffered with upper tract gastrointestinal perforation (GIPs), associated with NSAID use. More recently, the IL-6 receptor antagonist tocilizumab (TCZ) has been associated with lower tract GIPs. Janus kinase (JAK) inhibitors, including tofacitinib (TOF), with some downstream effects on IL-6 signalling, also have potential for an increased risk of GIPs.There is limited real-world evidence and almost no comparative evidence on the risk for GIP associated with TC...

Real-world Comparative Risks of Herpes Virus Infections in Tofacitinib and Biologic-treated Patients with Rheumatoid Arthritis

Ann Rheum Dis. 2016 Apr 25;0:1–5 doi: 10.1136/annrheumdis-2016-209131

Herpes Zoster (HZ) complications can cause considerable morbidity including debilitating pain syndromes. Clinical trials of tofacitinib have suggested it may increase the risk of HZ. Although unclear, the mechanism may involve reduced CD4 T-cell function and interference of interferon signalling. Following approval of tofacitinib in the US in 2012, real-world data from Medicare (2006–2013) and from the US longitudinal database, Marketscan, (2010–2014) were analysed. A total of 2526 patients who...

Pregnancy outcome after tocilizumab therapy in early pregnancy – a case series from the German Embryotox Pharmacovigilance Center

Reproductive Toxicology doi:10.1016/j.reprotox.2016.01.002

MTX users have an increased incidence of spontaneous abortions (SABs) compared to baseline risk (42.5%1 vs. 13-17%2). Tocilizumab (TCZ) has been shown to have similar efficacy with or without MTX. There is currently limited data on the effect of TCZ on pregnancy, but with more safety data, TCZ could be an alternative for RA patients of reproductive age. The patients were enrolled at Embryotox Berlin, a pharmacovigilance center providing risk assessment during pregnancy, between 2011 and 2014 dur...
