PK profile of TOF is rapid absorption and elimination with time to max concentration 0.5-1 hour and terminal half-life at 3 hours. It is currently approved for immediate release (IR) 5 mg BID, 10 mg total; however, decreasing the dosage to QD dosing may help increase compliance. This study performed in 24 healthy males compared the PK of XR and IR TOF under both single and multiple dose conditions and evaluated the effect of a high-fat meal on the PK of XR TOF. There were no clinically important...

Hypoxia is a key driving force in joint inflammation, however little is known about the effect it can have on JAK/STAT signalling in rheumatoid arthritis. Due to the development of JAK inhibitors as therapeutics it is important to understand any links there may be. Previous studies have shown that HIF1a, a protein associated with hypoxia, facilitates the binding of STAT3 to haptoglobin promoter in HepG2 human hepatoma cells. HIF1a also requires interaction of Notch signalling pathways with STAT3...

A large number of loci implicated in disease susceptibility have been identified through genome-wide association studies (GWAS). In this review article, Diogo et al. discuss recent advances in GWAS in the context of rheumatoid arthritis pathogenesis and clinical applications. Relevant cells types and pathways in RA highlighted by GWAS to date include regulatory T-cells and CD4+ memory T cells as well as the JAK/STAT and NF-kB signalling pathways. The development of drugs targeting these pathways...
