Tofacitinib as induction and maintenance therapy for ulcerative colitis

N Engl J Med. 2017 May 4;376(18):1723-1736. DOI 10.1056/NEJMoa1606910

Tofacitinib, at a dose of 10 mg twice daily, was more effective than placebo for induction of remission and mucosal healing in patients with moderately to severely active ulcerative colitis. Furthermore, maintenance therapy with tofacitinib, at a dose of either 5 mg or 10 mg twice daily, was more effective than placebo in sustaining remission and mucosal healing.

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 ...

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...

Lymphoma in the Tofacitinib Rheumatoid Arthritis Clinical Development Program

Arthritis Care Res (Hoboken). 2018 May;70(5):685-694. doi: 10.1002/acr.23421

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...
