Tocilizumab as Monotherapy or Combination Therapy for Treating Active Rheumatoid Arthritis: a Meta-analysis of efficacy and Safety Reported in Randomized Controlled Trials

Arthritis Res Ther 2016; 18:211. DOI 10.1186/s13075-016-1108-9

This is the first meta-analysis comparing efficacy and safety of TCZ monotherapy (TCZMONO) versus TCZ + csDMARD (TCZCOMBI) in patients with RA. The findings show that similar efficacy can be expected with TCZ monotherapy in patients with intolerance to csDMARDs compared with inadequate responders to csDMARDs who switch to TCZ add-on therapy.A total of 6679 patients from 13 studies were included, receiving: 1298, TCZMONO; 3077, TCZCOMBI; 2204, csDMARDs. Meta-analyses were performed for the follow...

RAPID3 and ACR/EULAR Provisional Definitions as Predictors of Radiographic Outcome in a Rheumatoid Arthritis Clinical Trial with Tocilizumab

Arthritis Care Res 2016; Accepted article. DOI 10.1002/acr.23008.

The findings reported represent the first validation of RAPID3 (Routine Assessment of Patient Index Data 3) remission ± SJC ≤1 as an alternative to the established SDAI or Boolean remission definitions, which can be time consuming and costly to measure. RAPID3 is a pooled index of the patient-reported measures: function, pain and Patient Global estimate of status.Data were analysed from the TociLIzumab Safety and THE Prevention of Structural Joint Damage (LITHE) study, a 2-year double-blind Phas...

Risk for Lower Intestinal Perforations in Patients with Rheumatoid Arthritis Treated with Tocilizumab in Comparison to Treatment with Other Biologic or Conventional Synthetic DMARDs

Ann Rheum Dis 2016;0:1–7 DOI 10.1136/annrheumdis-2016-209773.

This real-life study confirms findings from the tocilizumab (TCZ) clinical development program that IL-6 inhibition with TCZ may be associated with increased risk of lower intestinal perforation (LIP). Data were analysed from the RABBIT register of patients. The primary outcome was the incidence of LIPs in patients exposed to TCZ, csDMARDs, TNFis, abatacept, or rituximab. Thirty-seven LIPs were observed in 53,972 patient years. The proportion of patients who developed a LIP was higher in patient...

Pregnancy Outcomes in the Tofacitinib Safety Databases for Rheumatoid Arthritis and Psoriasis

Drug Saf. 2016 June 9; 39:755–762; DOI 10.1007/s40264-016-0431-z [Epub ahead of print]

RA and psoriasis may present in women of child-bearing potential, however there are currently no adequate or well-controlled studies of tofacitinib (TOF) or any DMARD in pregnant women. Pregnancy was an exclusion criterion of TOF randomized clinical trials because of the unknown effects of TOF on mother and child; TOF is a small molecule with the potential to cross the placenta. The current analysis looked at reported pregnancies and their outcomes from TOF RA and psoriasis clinical safety datab...

Efficacy and safety of the oral Janus kinase inhibitor peficitinib (ASP015K) monotherapy in patients with moderate to severe rheumatoid arthritis in Japan:a 12-week, randomised, double-blind, placebo-controlled phase IIb study

Ann Rheum Dis. 2016 Jun;75:1057-64. doi: 10.1136/annrheumdis-2015-208279. Epub 2015 Dec 15

Peficitinib (ASP015K) is a novel orally bioavailable JAK inhibitor in development for the treatment of RA. It inhibits JAK1, JAK2, JAK3 and Tyk2 enzyme activities and has moderate selectivity or JAK3 inhibition.Here the authors report the findings of a 12-week, randomized, double-blind, placebo-controlled phase IIb study evaluating efficacy, safety and dose response of peficitinib (25, 50, 100, or 150 mg) as once-daily oral monotherapy in Japanese patients with moderate to severe RA. The primar...

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...

Two-year Efficacy of Tocilizumab in Patients with Active Rheumatoid Arthritis in Clinical Practice

Reumatol Clin. 2016; May 10 doi: 10.1016/j.reuma.2016.03.014 [Epub ahead of print]

The efficacy and safety of tocilizumab has been studied in several randomized clinical trials (RCTs) but due to the strict inclusion and exclusion criteria of RCTs, real-life observational studies are needed to supplement the findings from these trials. This small longitudinal, open-label study from an outpatient clinic in Spain evaluated the effectiveness, survival rate and reasons for treatment discontinuations in 85 patients treated with tocilizumab over a 24-month period. The study also ass...

Efficacy and Safety of Baricitinib in Japanese Patients with Active Rheumatoid Arthritis Receiving Background Methotrexate Therapy: A 12-week, Double-blind, Randomized Placebo-controlled Study

J Rheumatol. 2016;43(3):504–511.

Clinical trials have shown baricitinib once daily to be effective in patients with RA. However, this Janus kinase (JAK) 1/JAK2 inhibitor has not been evaluated in a Japanese population. In this 12-week, placebo-controlled study, 145 Japanese patients were enrolled and received placebo, 1 mg, 2 mg, 4 mg or 8 mg oral baricitinib daily. Efficacy results were encouraging and consistent with earlier trials. Significantly more baricitinib patients achieved ACR20 response at Week 12 of treatment compar...

The Efficacy and Safety of Clazakizumab, an Anti-Interleukin-6 Monoclonal Antibody, in a Phase 2b Study of Adults with Active Psoriatic Arthritis

Arthritis Rheumatol. 2016 Mar 24. DOI 10.1002/art.39700 [Epub ahead of print]

Encouraging results have been seen with clazakizumab in RA, but the results of anti-IL6 therapy in patients with psoriatic arthritis (PsA) have so far been unclear. This Phase 2b dose-ranging study examined the efficacy and safety of clazakizumab given subcutaneously q4w, with or without MTX, in 165 patients with PsA who had inadequate response to NSAIDs.ACR20 response at Week 16, the primary endpoint, was significantly higher in patients receiving clazakizumab 100 mg compared with placebo (52.4...

Initial Experience with Tofacitinib in Clinical Practice: Treatment Patterns and Costs of Tofacitinib Administered as Monotherapy or in Combination with Conventional Synthetic DMARDs in 2 US Health Care Claims Databases

Clin Ther. 2016 Mar 28. doi: 10.1116/j.clinthera. 2016.03.038 [Epub ahead of print]

This study analyzes data from two US claims databases between November 2012 and June 2014. It was designed to build upon knowledge from tofacitinib Phase 3 clinical trials providing clinical insights from independent sources on treatment patterns and costs for tofacitinib. Data were collected from 337 patients in the Truven Marketscan (TM) and 118 patients in the Optum Clinformatics (OC) databases. In this early experience cohort for tofacitinib, approximately 75% of patients had previously rece...
