When every-2-week administration of long-acting ESAs is extended to every 4 weeks, efficacy either remains stable or decreases incrementally. The GAIN trial (Gain effectiveness in Anemia treatment with NeoRecormon®) was designed to compare anemia management with epoetin beta, epoetin alpha or darbepoetin alpha in HD patients. An interim analysis of data from 1005 stable HD patients suggested that switching to epoetin beta from either epoetin alpha or darbepoetin alpha resulted in improved efficacy and a 20% dose reduction in SC epoetin beta.\n\nThe aim of the study is to compare two schedules of anaemia treatment in HD patients using two different erythropoietic stimulating agents (epoetinum beta vs darbepoetinum) with respect to the efficacy in anaemia correction and to the haemoglobin (Hb) level stability.\n\nThis is a multicenter (2 centers), prospective, open-label, parallel, controlled trial of therapy equivalence', 'detailedDescription': 'Currently available ESAs include epoetin alfa, epoetin beta, and darbepoetin. Epoetin alfa and beta have been designed to resemble closely the endogenous molecule and have similar pharmacokinetics. They are considered "short-acting" in comparison to darbepoetin, a second-generation molecule with a prolonged half-life, which is considered "long-acting." European and American Best Practice Guidelines (EBPG) recommend preferential subcutaneous (SC) twice- to thrice-weekly epoetin administration. There is a great deal of evidence that once-weekly SC administration of epoetin beta to be equally efficient and well tolerated in HD patients, even in those requiring high weekly epoetin doses. Several recent reports support the efficacy of once every-other-week epoetinum administration in the maintenance phase of the anaemia treatment in predialysis, haemodialysis and in peritoneal dialysis CKD patients.\n\nHowever, there are studies suggesting that in HD patients receiving SC short-acting ESA therapy, ESA efficacy decreases when the dosing is extended from thrice-weekly to once-weekly administration.
