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 ...

Efficacy, Safety, Pharmacokinetics, and Pharmacodynamics of Filgotinib, a Selective Janus kinase 1 Inhibitor, after Short-term Treatment of Rheumatoid Arthritis: Results of Two randomized Phase IIA Trials

Arthritis Rheumatol. 2017 Oct;69(10):1949-1959. doi: 10.1002/art.40186

In two 4-week exploratory Phase 2a trials in MTX-inadequate responder (IR) patients with RA, the highly selective JAK1 inhibitor filgotinib met the primary endpoint of ACR20 at Week 4, showing greater response than placebo.Study 1, a proof-of-concept study, included 127 patients randomised to placebo, filgotinib 100 mg BID or filgotinib 200 mg QD. Study 2, was a dose-ranging study and included 91 patients randomised to placebo, filgotinib 30 mg QD, filgotinib 75 mg QD, filgotinib 150 mg QD or fi...

Filgotinib (GLPG0634/GS-6034), an oral selective JAK1 inhibitor, is effective as monotherapy in patients with active rheumatoid arthritis: results from a randomised, dose-finding study (DARWIN 2)

Ann Rheum Dis 2017;76:1009–19

In these two Phase 2b studies, filgotinib (a selective JAK-1 inhibitor) was shown to improve the signs and symptoms of RA (compared with placebo), either as monotherapy or when added to MTX.DARWIN 1 included 594 patients with moderate to severe RA on a stable dose of MTX, while DARWIN 2 included 283 patients who stopped taking MTX before the start of the study. After 12 weeks’ treatment, significantly more patients who were receiving filgotinib 100 mg or 200 mg daily in DARWIN 1 or any filgotini...

Baricitinib in Patients with Inadequate Response or Intolerance to Conventional Synthetic DMARDs: Results from the RA-BUILD Study

Ann Rheum Dis 2017;76:88–95.

Baricitinib improved symptoms of RA in the RA-BUILD trial, a Phase 3 study of baricitinib in patients with moderately to severely active RA, refractory to or intolerant to csDMARDs. As well as providing a short-term (24 weeks) benefit, there appeared to be joint damage benefit, considered a marker of long-term disability.RA-BUILD was a 24-week randomised, double-blind, placebo-controlled parallel-group study. Patients were randomised 1:1:1 to receive once-daily doses of placebo (n=228) or barici...

Baricitinib, Methotrexate, or Combination in Patients with Rheumatoid Arthritis and no or Limited Prior Disease-Modifying Antirheumatic Drug Treatment

Arthritis Rheumatol 2016. DOI 10.1002/art.39953. Accepted article

In this 52-week study of patients receiving initial therapy for RA, baricitinib alone or in combination with MTX demonstrated superior efficacy compared with MTX alone.Patients naïve to csDMARD (no or <3 doses of MTX) or bDMARD were randomised 4:3:4 (N=588) toMTX QW, baricitinib 4 mg QD or baricitinib 4 mg QD + MTX QW. The primary endpoint assessment was noninferiority of baricitinib monotherapy to MTX based on ACR20 response at Week 24.Not only was the primary endpoint met, baricitinib monother...

A Randomized Phase 2b Study of ABT-494, a Selective JAK Inhibitor in Patients with Rheumatoid Arthritis and an Inadequate Response to Methotrexate

Arthritis Rheumatol 2016; Accepted article DOI 10.1002/art-39808 [Epub 2016]

This dose-ranging study evaluated the efficacy of the novel, selective JAK1 inhibitor ABT-494 versus placebo in patients with moderate-to-severe RA and inadequate response (IR) to MTX.In this 12-week, randomised, double-blind study (BALANCE II), the efficacy and safety ofABT-494 dosed at 3mg, 6 mg, 12 mg, 18 mg (all twice daily) and 24 mg (once daily) was assessed. Patients included had not received prior biologic therapy.Of the 299 patients included in the analysis, the proportions of patients ...

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...

Calprotectin more accurately discriminates the disease status of rheumatoid arthritis patients receiving tocilizumab than acute phase reactants

Rheumatology. 2015 Aug 4. doi:pii: kev251. [Epub ahead of print]

Calprotectin is a member of the S100 protein family that has strong pro-inflammatory effects that reflect local ongoing inflammation rather than systemic response, due to its release at local inflammation sites. High calprotectin levels have been found in SF and serum from RA patients and correlate with disease activity. This study analysed the accuracy of calprotectin compared to acute phase response in discriminating the clinical disease status of RA patients receiving TCZ. A clinical assessme...
