Long-term Effectiveness of Tocilizumab in Patients with Rheumatoid Arthritis, Stratified by Number of Previous Treatment Failures with Biologic Agents: Results from the German RABBIT Cohort

Rheumatol Int 2018 Apr; 38(4):579-87

In this observational study, the German RABBIT cohort was used to assess the long-term effectiveness and retention rates of tocilizumab (TCZ) in patients with prior bDMARD failures. Results of the study suggested that TCZ could be an effective treatment option for patients with difficult-to-treat RA. A total of 885 patients were involved in the study and these were categorised dependent on the number of bDMARD failures they had prior to TCZ treatment. Patient data recorded in the cohort included...

Effect of Glucocorticoids on the Clinical and Radiographic Efficacy of Tofacitinib in Patients with Rheumatoid Arthritis: A Posthoc Analysis of Data from 6 Phase III studies

J Rheumatol 2018 Feb; 45(2):177-87

In this post hoc analysis, six Phase 3 studies were used to analyse the effect of glucocorticoids (GC) on the efficacy of tofacitinib (TOF) in patients with RA. Concomitant use of GC did not affect the clinical or radiographic outcomes of patients treated with TOF. Data from all six clinical trials were evaluated, with four studies (ORAL Scan, ORAL Standard, ORAL Sync and ORAL Step) being pooled for analysis. In these studies, MTX was used as a comparison and patients were required to maintain a...

JAK Inhibition as a Therapeutic Strategy for Immune and Inflammatory Diseases

Nat Rev Drug Discov 2017;16:843–62 DOI: 10.1038/nrd.2017.201

Janus kinases (JAKs) are essential mediators of downstream signaling pathways in many inflammatory and autoimmune diseases. This review summarizes current clinical data on first- and second-generation JAK inhibitors (jakinibs) and discusses their use for the treatment of immune and inflammatory conditions.First generation jakinibs such as tofacitinib, baricitinib, and ruxolitinib, non-selectively inhibit JAK-dependent pro-inflammatory cytokines, which are major contributors to immunopathology. T...

Successful Treatment of Arthritis Induced by Checkpoint Inhibitors with Tocilizumab: a Case Series

Ann Rheum Dis 2017;76:2061-64. doi: 10.1136/annrheumdis-2017-211560

This case series evaluated the use of tocilizumab (TCZ) as an effective treatment for patients who develop arthritis as an adverse event (AE) of immune checkpoint inhibitor (ICI) cancer treatment. Results suggested that TCZ was an effective treatment, as it reduced the arthritis disease progression.ICIs have been defined as a revolutionary treatment for metastatic melanomas; however, a common AE is the development of polyarthritis. Current arthritis treatments reduce the efficiency of ICI therap...

Tofacitinib Therapy for Rheumatoid Arthritis: A Direct Comparison Study between Biologic-naive and Experienced Patients

Intern Med. 2018 Mar 1;57(5):663-670. doi: 10.2169/internalmedicine.9341-17

This 6-month prospective direct comparison study analysed the effectiveness of tofacitinib (TOF) therapy on bDMARD-naïve and bDMARD-experienced patients. bDMARD-naïve patients were more responsive to TOF therapy than bDMARD-experienced patients.The study analysed the data of 113 patients diagnosed with high or moderate disease activity, defined using CDAI scores. All patients had failed to achieve CDAI low disease activity or remission with MTX therapy for ≥3 months. Patients were given 5 mg TOF...

Herpes Zoster and Tofacitinib: Clinical Outcomes and the Risk of Concomitant Therapy

Arthritis Rheumatol 2017;69(10):1960–68

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...

Tofacitinib or Adalimumab versus Placebo for Psoriatic Arthritis

N Engl J Med 2017; 377:1537-50. DOI: 10.1056/NEJMoa1615975

In the Phase 3 OPAL Broaden trial of patients with active psoriatic arthritis (PsA) with inadequate response to ≥1 csDMARD, superior efficacy was observed in patients treated with tofacitinib (TOF) compared with those given placebo. Patients were randomised to: 5 mg TOF BID, 10 mg TOF BID, 40 mg adalimumab administered subcutaneously q2W, or placebo with a switch to 5 mg TOF at Month 3. Adalimumab was used as an active control in the study. A variety of primary and secondary endpoints were used ...

Tofacitinib for Psoriatic Arthritis in Patients with an Inadequate Response to TNF Inhibitors

N Engl J Med 2017;377:1525–36.

The study data presented that tofacitinib (TOF) improves efficacy response rates in patients with severe psoriatic arthritis (PsA) who have an inadequate response to TNF inhibitors.The Phase 3 Oral Psoriatic Arthritis Trial (OPAL) Beyond study evaluated patients with active PsA who had inadequate responses to more than one TNFi. Patients were randomised 2:2:1:1 to 5 mg TOF BID or 10 mg TOF BID for 6 months; or PBO, with a switch to 5 mg TOF BID or to 10 mg BID at 3 months.Primary endpoints were ...

Safety and Efficacy of Baricitinib in Elderly Patients with Rheumatoid Arthritis

RMD Open. 2017; 3(2): e000546. doi: 10.1136/rmdopen-2017-000546

In this post hoc analysis of pooled data from two randomised controlled trials, RA-BUILD and RA-BEAM, age was shown not to be a contraindication for use of baricitinib. Patients in RA-BUILD were csDMARD-inadequate responder(IR) patients who received an oral placebo or 2 mg or 4 mg baricitinib once daily. Patients in RA-BEAM were MTX-IR patients and received an oral placebo, 4 mg baricitinib once daily or subcutaneous adalimumab every 2 weeks. Efficacy and safety of baricitinib in elderly patient...

Treatment Persistence and Healthcare Costs Among Patients with Rheumatoid Arthritis Changing Biologics in the USA

Adv Ther. 2017 Nov;34(11):2422-2435. doi: 10.1007/s12325-017-0617-5

Updated treatment guidelines recommend the use of different mechanism of action (MOA) therapies earlier in the treatment course. Clinical studies have revealed that this approach may be better than TNFi cycling, and may be more cost effective.This study of Commercial and Medicare Advantage claims data showed that patients who switched MOA had higher treatment persistence and lower healthcare costs than TNFi cyclers.After the first TNFi claim, patients either cycled to another TNFi (n=935) or swi...
