This Phase 2b study of VX-509 (decernotinib), a selective JAK3 inhibitor, showed that VX-509 in combination with stable DMARD therapy was effective for improving synovitis and osteitis as assessed by MRI in patients who had an inadequate response to DMARD therapy.Patients were randomised to treatment groups receiving either placebo, VX-509 100 mg, 200 mg or300 mg for 12 weeks. Minimum inclusion criteria included Grade ≥2 clinical synovitis in either the wrist or two metacarpophalangeal joints. A...

Evidence is presented that treatment with sarilumab improves patient-reported outcomes (PROs). These improvements complement the clinical efficacy previously reported for sarilumab.Data were analysed from the 52-week Phase 3 MOBILITY randomised controlled trial in adult patients with active RA and previous inadequate response to MTX. Patients received subcutaneous placebo or sarilumab 150 mg or 200 mg every 2 weeks in combination with MTX, for 52 weeks.PROs assessed were: Patient Global Assessme...

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 ...

VX-509 (decernotinib) is a novel oral, selective inhibitor of JAK-3. JAK-3 is a member of the JAK signalling family that is primarily expressed in hematopoietic cells and associates with only the common γ-chain making it a promising therapeutic drug target. A phase IIb 24-week study of VX-509 in 358 patients with RA, who had prior inadequate response to MTX, uses ACR20 response rate and DAS28-CRP change at Week 12 to assess the efficacy of VX-509. Patients were administered either placebo+MTX or...

Sarilumab plus methotrexate in patients with active rheumatoid arthritis and inadequate response to methotrexate: Results of a phase III study

Biologic DMARDs targeting TNF-alpha, IL-1, T-cell co-stimulatory blockade, B-cell depletion, and IL-6R, as well as the newer JAK inhibitors have greatly improved clinical outcomes in RA. However, not all patients respond to current biologic or small molecule DMARDs.

Sarilumab is a fully human anti-IL-6Rα mAb that binds membrane-bound and soluble human IL-6R with high affinity, blocking cis and trans IL-6-mediated signalling. This study (MOBILITY) is the first randomised, double-blin...

Recent innovations in the treatment of RA have focused on the use of small molecules to inhibit intracellular kinases such as the JAK family. Baricitinib (LY3009104, formerly INCB028050) is an orally administered, potent, selective and reversible inhibitor of JAK1 and JAK2, which has shown anti-inflammatory effects, as well as preservation of cartilage and bone, in preclinical rodent studies.

This phase IIb study was designed to investigate multiple doses and dosing regimens of baricitin...

This is the first phase 2 study to be published for spleen tyrosine kinase (Syk) inhibitor R788 (fostamatinib). This phase 2 study ingestigated the efficacy and safety of fostamatinib in patients with active RA despite long-term treatment with methotrexate. In this 6-month, double-blind, placebo-controlled trial, patients were randomised to receive two doses of R788 (100 mg twice daily or 150 mg once daily) or placebo once or twice daily. Significantly more patients on R788 achieved ACR 20 respo...

An oral Syk kinase inhibitor in the treatment of rheumatoid arthritis: a three-month randomized, placebo-controlled, phase II study in patients with active rheumatoid arthritis that did not respond to biologic agents

This was the first phase 2 study to be published investigating the efficacy and safety of the spleen kinase (Syk) inhibitor R788 (fostamatinib) in patients with refractory rheumatoid arthritis (RA). In this multicentre, randomised, double-blind, placebo-controlled, 3-month trial, patients with active RA on stable background treatment (excluding biologics) were randomised to receive 100 mg R788 or placebo twice daily. Differences in ACR20 responses were significant at week 6 (p=0.003), but not th...

This phase 2 clinical trial assessed the influence of fostamatinib on patient reported outcomes (PROs) in 457 patients with active rheumatoid arthritis (RA) and an inadequate response to methotrexate (MTX). Patients received either placebo or fostamatinib 100 mg twice daily or 150 mg once daily (1:1:1) for 24 weeks in addition to their baseline MTX. Patients taking fostamatinib 100 mg twice daily had statistically significant improvements in health-related quality of life scores for pain, patien...
