Five-year Efficacy and Safety of Tocilizumab Monotherapy in Patients with Rheumatoid Arthritis who were Methotrexate- and Biologic-naïve or Free of Methotrexate for 6 Months: the AMBITION Study

Jones G, Wallace T, McIntosh MJ, Brockwell L, Gómez-Reino JJ, Sebba A.
J Rheumatol 2017;44:2. DOI 10.3899/jrheum.160287.

Results from the AMBITION study (Actemra versus Methotrexate double-Blind Investigate Trial In mONotherapy), showed the continuing efficacy and safety of tocilizumab up to 264 weeks. AMBITION was a 24-week randomised controlled trial in patients with active RA who were either MTX-naïve or MTX-free for 6 months prior to study entry. Patients received TCZ 8 mg/kg IV Q4W or oral MTX weekly (7.5 mg dose escalating to 20 mg). For those patients who then entered the long-term extension (LTE) stu...

Systematic review and meta-analysis of serious infections with tofacitinib and biologic disease-modifying antirheumatic drug treatment in rheumatoid arthritis clinical trials

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. ...

The effect of tofacitinib on pneumococcal and influenza vaccine responses in rheumatoid arthritis

Winthrop KL, Silverfield J, Racewicz A, Neal J, Lee EB, Hrycaj P, Gomez-Reino J, Soma K, Mebus C, Wilkinson B, Hodge J, Fan H, Wang T, Bingham CO 3rd.
Ann Rheum Dis. 2015 Mar 20. pii: annrheumdis-2014-207191. doi: 10.1136/annrheumdis-2014-207191. [Epub ahead of print]

The increased risk of serious infection among RA patients means vaccinations against pneumococcus and influenza are recommended in this group of patients. Studies evaluating immune response to these vaccines in conjunction with DMARD therapy can provide clinicians with important information relating to things such as timing of vaccination. This study aimed to assess the effect of tofacitinib on vaccine responses to PPSV-23 and the trivalent seasonal influenza vaccine in those whom tofacitinib...

Lipid profile changes in patients with chronic inflammatory arthritis treated with biologics and tofacitinib in randomized clinical trials: A systematic review and meta-analysis

Souto A, Salgado E, Maneiro JR, Mera A, Carmona L, Gómez-Reino JJ.
Arthritis Rheumatol. 2015;67(1):117–127

Systemic inflammation, reflected by high levels of C-reactive protein and the erythrocyte sedimentation rate, has been identified as an independent risk factor for cardiovascular disease, the most important cause of death in RA and SpA. Studies with TNF antagonists have given contradictory results on cardiovascular risk. As such, this systemic literature search aimed to analyse lipid changes in RA and SpA subjects treated with biologics or tofacitinib in randomized clinical trials. The search ...

Analysis of Infections and All-Cause Mortality in Phase II, III and Long-Term Extension Studies of Tofacitinib in Patients with Rheumatoid Arthritis

Cohen S, Radominski SC, Gomez-Reino JJ, et al.
Arthritis Rheumatol. 2014;66(11):2924–2937

This study pools data from the global tofacitinib RA development programme (phase II, phase III and long-term extension studies) to determine the rate of infections and all-cause mortality with tofacitinib treatment. In total, 4,789 patients within these studies received tofacitinib, at varying doses and with varying duration. The overall incidence rate of serious infections was 3.09 events/100 patient-years (95% CI 2.73–3.49), which was stable over time, with pneumonia and skin and s...

El inhibidor de la JAK tofacitinib para la artritis reumatoide: resultados de estudios de fase III

Salgado E & Gomez-Reino JJ.
International Journal of Clinical Rheumatology June 2013; 8(3):311–13

The tofacitinib ORAL research program involves six phase 3 trials (Standard, Solo, Step, Scan, Sync and Start) to assess the safety and efficacy of tofacitinib 5 and 10 mg twice daily as monotherapy, or with either background MTX or traditional DMARD therapy. This report by Salgado et al. provides an overall analysis of the each of the study designs and the clinical results to date. The results show that tofacitinib effectively controlled the signs and symptoms of RA across a range of patient po...
