Differential Properties of Janus Kinase Inhibitors in the Treatment of Immune-mediated Inflammatory Diseases

Rheumatology (Oxford) 2023;63(2):298–308 doi 10.1093/rheumatology/kead448

JAKis differ in structure, which affects their inhibitory concentration for different JAKs.

This review by Taylor, et al. compares the pharmacological profiles of JAKis, including abrocitinib, baricitinib, filgotinib, peficitinib, tofacitinib, and upadacitinib.

Blocking the IL-6R is a major therapeutic advance for many diseases in adults and children. Updated consensus statement provides guidance to rheumatologists and other experts, as well as patients and administrators, on managing patients with the use of drugs blocking the IL-6 pathway.

JAKi are approved in various immune-mediated inflammatory diseases. With five JAKi now licensed, this paper reviews key points to consider in their use to assist clinicians, patients, and other stakeholders once the decision is made to commence JAKi.The consensus was developed by a Steering Committee and an expanded Task Force using EULAR standard operating procedures. The committee included patients as well as experts in rheumatology, gastroenterology, haematology, dermatology, and infectious d...

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...

Despite preclinical and healthy volunteer studies of tofacitinib showing no evidence of nephrotoxicity, increases in mean serum creatinine levels have been observed in patients treated with the drug during the RA clinical development programme. This report explores the clinical significance of this change.

Serum creatinine values and renal adverse event data were pooled from patients who received =1 dose of tofacitinib either with background DMARDs or as monotherapy in five Phase 3 studie...
