Tofacitinib regulates synovial inflammation in psoriatic arthritis, inhibiting STAT activation and induction of negative feedback inhibition

Annals of the Rheumatic Diseases. 2015 Sep 9. doi:10.1136/annrheumdis-2014-207201

Psoriatic arthritis (PsA) is a chronic inflammatory arthritis associated with psoriasis (Ps) and characterised by synovitis and progressive destruction of articular cartilage and bone. Recently developed agents for PsA target IL12p40, IL-6 and IL-17, several of which signal through the JAK family of receptor-associated tyrosine kinases. Tofacitinib is a drug of the JAK inhibitor class and is currently approved for the treatment of RA in 27 countries. This study evaluated the effect of tofacitini...

Long-term Safety of Tocilizumab: Results from 3 Years of Followup Postmarketing Surveillance of 5573 Patients with Rheumatoid Arthritis in Japan

The Journal of Rheumatology. 1 June 2015 DOI: 10.3899/jrheum.141210 [Epub ahead of print]

The humanised anti-interleukin 6 receptor monoclonal antibody tocilizumab (TCZ) has been available in clinical practice for several years. The purpose of this study was to evaluate the long-term safety of for the treatment of RA in a real-world clinical setting as a long-term extension of a single-arm, observational post marketing surveillance study. Data on selected adverse events (AEs) - fatal events, serious infection, malignancy, GI perforation, and serious cardiac dysfunction - were collect...

Mean increases from baseline in patient serum creatinine (SCr) levels have been observed in the clinical development programme for the JAK inhibitor tofacitinib. These increases predominantly occurred within the first three months, and reversed with tofacitinib withdrawal.

This phase 1, randomised, placebo-controlled, parallel-group, 2-period study assessed changes in measured glomerular filtration rate (mGFR) with tofacitinib, relative to placebo, in 148 patients with active RA. Result...

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

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...

Super-enhancers delineate disease-associated regulatory nodes in T cells

Transcription machinery (proteins responsible for activating or ‘switching off’ genes) is not distributed in the genome in a symmetrical (or even) manner. Some parts of the genome, so called super-enhancers (SEs), accumulate an exceptionally high level of proteins relevant to the regulation of transcription (i.e. the machinery is concentrated in particular parts of the genome). In this paper, the investigators asked about the locale of these regions in the genome of T cells. Then they addressed...
