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.

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...

Analysis of Non-melanoma Skin Cancer across the Tofacitinib Rheumatoid Arthritis Clinical Programme

Clin Exp Rheumatol 2017;35:614–22

Because non-melanoma skin cancer (NMSC) is one of the most common malignancies associated with RA immunomodulatory therapies, this analysis looked to determine the rate of NMSC incidence per 100 patient-years in patients with RA receiving TOF in the clinical trial programme. The Phase 1, 2, and 3 IRs (combined) for both TOF 5- and 10 mg were low and comparable to those of adalimumab, MTX and placebo, IRs remained stable over time. TOF doses used in the 2 Phase 1; 8 Phase 2; and 6 Phase 3 studies...

Biologic or Tofacitinib Monotherapy for Rheumatoid Arthritis in People with Traditional Disease-modifying Anti-rheumatic Drug (DMARD) Failure: a Cochrane Systematic Review and Network meta-analysis (NMA)

Cochrane Database Syst Rev 2016;11:CD012437.

Treatment options for RA patients who are MTX/DMARD incomplete responders (IR) include other DMARDs, biologics or tofacitinib (TOF). However, there is a lack of direct head-to-head comparator trials of biologics in people with RA. This review provides an update of the 2009 Cochrane overview, ‘Biologics for rheumatoid arthritis’,1 and provides comparisons and estimates for biologic or TOF monotherapy in MTX/DMARD-IR people with RA.The benefits and harms of biologic monotherapy (TNFis: adalimumab,...

Biologics or Tofacitinib for Rheumatoid Arthritis in Incomplete Responders to Methotrexate or Other Traditional Disease-Modifying Anti-Rheumatic Drugs: A Systematic Review and Network Meta-Analysis

Cochrane Database of Systematic Reviews 2016 Issue 5. Art. No.: CD012183 [DOI: 10.1002/14651858.CD012183].

Treatment options for RA patients who are MTX/DMARD incomplete responders (IR) include other DMARDs, biologics or tofacitinib (TOF). However, there is a lack of head-to-head studies to show any important differences between these options in terms of benefits and harms. This review provides an update of the 2009 Cochrane overview and network meta-analysis (NMA) of biologics for RA.1Nine biologics (abatacept, adalimumab, anakinra, certolizumab pegol, etanercept, golimumab, infliximab, rituximab, a...

Tofacitinib, an oral Janus kinase inhibitor: analysis of malignancies across the rheumatoid arthritis clinical development programme

Ann Rheum Dis. 2015 Apr 22. pii: annrheumdis-2014-205847. doi: 10.1136/annrheumdis-2014-205847. [Epub ahead of print]

The developments of certain malignancies associated with chronic inflammatory diseases such as RA is known to occur to a greater extent than that of the general population. It is also know that certain RA treatments can affect malignancy rates. As such, newer immunomodulatory agents, such as the JAK inhibitor tofacitinib, are closely monitored for safety events of special interest, including malignancies.

This paper analyses pooled malignancy data from the tofacitinib RA clinical develop...

Molecular pathways: Molecular basis for sensitivity and resistance to JAK inhibitors

Clin Cancer Research doi:10.1158/1078-0432.CCR-13-0279

Janus kinases (JAKs) mediate the regulation of a variety of cytokine signals with alterations in JAK1, JAK2, JAK3 and Tyk2 signalling contributing to many disease states including autoimmune diseases and haematological malignancies. Recently tofacitinib and ruxolitinib have been approved for treatment for rheumatoid arthritis and myelofibrosis respectively. Several JAK2 inhibitors, such as momelotinib and pacritinib, currently in development for myelofibrosis and the JAK1/2 inhibitor baricitinib...

Safety of synthetic and biological DMARDs: a systematic literature review informing the 2013 update of the EULAR recommendations for the management of rheumatoid arthritis

Ann Rheum Dis doi:10.1136/annrheumdis-2013-204575

Two systematic literature reviews were undertaken to update the safety findings on synthetic and biological DMARDs in order to inform the updates to the EULAR recommendations to the treatment of RA. Of 10,559 articles screened, 49 were included for review covering a diverse range of outcomes. In the main these showed the patients on bDMARDs had a significantly greater risk of serious infections and tuberculosis compared with csDMARDs, while differences in data between studies mean a slight incre...

Targeting the SYK-BTK axis for the treatment of immunological and hematological disorders: recent progress and therapeutic perspectives

Pharmacol Ther. 2013 May; 138(2):294–309

This review focuses on targeting spleen tyrosine kinase (SYK) and Bruton’s tyrosine kinase (BTK) inhibitors as potential immunomodulatory agents for the treatment of autoimmune and inflammatory disorders with SYK inhibition showing encouraging efficacy in patients with RA. The paper describes the role of SYK and BTK in several therapy areas including autoimmune diseases, allergic inflammatory disorders and haematological cancers as well as their role in innate immunity and regulators of adaptive...
