The effect of roxadustat (FG-4592) on individuals with chronic kidney diseases (CKD) patients receiving or not receiving the dialysis was unclear. The aim of this study was to evaluate the efficacy of roxadustat for the treatment of anemia in patients who are dialysis dependent (DD) or dialysis independent (NDD) CKD. We performed a systematic review of randomised controlled trials (RCTs) comparing treatment with roxadustat versus placebo or epoetin alfa up to November 2019. ⋯ The percentage change in the transferrin saturation levels was -2.07 % (-6%, NDD patients versus placebo, and +3.7 % in DD patients versus epoetin alfa) in anemia associated CKD patients. This review found roxadustast increases the levels of hemoglobin, serum transferrin, intestinal iron absorption, and reduces hepcidin in both NDD and DD-CKD patients. Safety data is still emerging.

Prostaglandin D2 (PGD2) is a pleiotropic mediator, significantly involved in the pathogenesis of type 2 (T2) asthma because of its biologic actions exerted on both immune/inflammatory and airway structural cells. In particular, the pro-inflammatory and pro-remodelling effects of PGD2 are mainly mediated by stimulation of chemoattractant receptor-homologous molecule expressed on Th2 cells (CRTH2). ⋯ Indeed, fevipiprant appears to be safe and effective, especially in consideration of its ability to inhibit eosinophilic bronchial inflammation and improve forced expiratory volume in one second (FEV1). Further ongoing phase III trials will definitely clarify if fevipiprant can prospectively become a valid option for an efficacious add-on treatment of moderate-to-severe T2-high asthma.
