BACKGROUND: Renal anemia is one of the most common complications of chronic kidney disease. This real-life study assessed the effectiveness of methoxy polyethylene glycol-epoetin beta, a continuous erythropoietin receptor activator (C.E.R.A.), for the treatment of chronic kidney disease (CKD)-associated anemia in patients receiving dialysis in daily clinical practice. METHODS: 247 patients receiving chronic intermitted dialysis in 26 centers in Poland with CKD-associated symptomatic anemia, ESA-naïve, and with balanced iron stores in the investigators' opinion were enrolled this real-life study...

Conjugation of epoetin beta (EPO) with methoxypolyethylene glycol-succinimidyl butanoate (mPEG-SBA) was studied. The compound mPEG-SBA was synthesized from mPEG, and the obtained intermediates and final product were analyzed by a reversed-phase chromatographic system equipped with an evaporative light scattering detector. Labeling the hydroxyl group in PEGs with benzoyl chloride and succinimide with benzylamine was applied to resolve and characterize different PEGs. The synthesized mPEG-SBA was used for the PEGylation of EPO...

BACKGROUND: Chronic kidney disease (CKD) is a global disease, and the number of people affected is increasing due to driving factors such as diabetes, obesity, and hypertension, as well as increased life expectancy. Many patients with CKD suffer anemia throughout the period of their disease. AIM: This research aimed to investigate the relation between resistance to the methoxy polyethylene glycol-epoetin beta (ME-β) and angiotensin-converting enzyme (ACE) gene polymorphism...

BACKGROUND: Erythropoiesis-stimulating agents (ESAs) are commonly used to treat anaemia in people with chronic kidney disease (CKD). However, their use has been associated with cardiovascular events. This is an update of a Cochrane review first published in 2014. OBJECTIVES: To compare the efficacy and safety of ESAs (epoetin alfa, epoetin beta, darbepoetin alfa, methoxy polyethylene glycol-epoetin beta, and biosimilar ESAs against each other, placebo, or no treatment) to treat anaemia in adults with CKD...

Antibodies that bind polyethylene glycol (PEG) can be induced by pegylated biomolecules and also exist in a significant fraction of healthy individuals who have never received pegylated medicines. The binding affinity of antibodies against PEG (anti-PEG antibodies) likely varies depending on if they are induced or naturally occurring. Anti-PEG antibodies can accelerate the clearance of pegylated medicines from the circulation, resulting in loss of drug efficacy, but it is unknown how accelerated blood clearance is affected by anti-PEG antibody affinity...

BACKGROUND: Because health plans each issue their own policies, drug coverage can vary. This variation can result in patients having unequal access to treatment. In this study, we evaluate commercial health plans' coverage policies for erythropoiesis-stimulating agents (ESAs) for patients with anemia resulting from chronic kidney disease (CKD). OBJECTIVES: To assess how a set of US commercial health plans cover ESAs for patients with anemia due to CKD. Our second objective was to examine the evidence that the plans reviewed when formulating their coverage policies...

PURPOSE: Previous studies reported that the long-acting erythropoiesis-stimulating agent (ESA) significantly suppresses the expression of hepcidin, which regulates iron availability. In this study, we compared the iron availability for erythropoiesis between short and long-acting ESA over a long period. METHODS: We enrolled 69 hemodialysis patients in this study. All patients were treated with short-acting ESA (epoetin-α or epoetin-β) for the first 30 months...

Anemia is an important complication in patients with chronic kidney disease. Peritoneal dialysis (PD) is one of the most common modalities of kidney replacement therapy for patients with end-stage kidney disease. PD is particularly prevalent in the Asian Pacific region. Among the different countries and regions, including mainland China, Hong Kong, Japan, Malaysia, Singapore, South Korea, and Thailand, PD accounts for 2.8% to 74.6% of the dialysis population. In addition, 82% to 96% of the PD populations from these countries and regions are receiving erythropoiesis-stimulating agents (ESAs)...

BACKGROUND: Daprodustat is an oral agent that stimulates erythropoiesis by inhibiting the prolyl hydroxylases which mark hypoxia-inducible factor for degradation through hydroxylation. Its safety and efficacy (noninferiority) were assessed in this 52-week, open-label study. METHODS: Japanese patients not on dialysis (ND) (N = 299) with anemia of CKD (stages G3, G4, and G5) with iron parameters of ferritin >100 ng/mL or transferrin saturation >20% at screening were randomized to daprodustat or epoetin beta pegol (continuous erythropoietin receptor activator [CERA], also known as methoxy polyethylene glycol-epoetin beta)...

BACKGROUND: Despite the widespread use of erythropoiesis-stimulating agents (ESAs) to treat anaemia, the risk of adverse outcomes associated with the use of different types of ESAs in non-dialysis chronic kidney disease (CKD) is poorly investigated. METHODS: From a pooled cohort of four observational studies, we selected CKD patients receiving short-acting (epoetin α/β; n = 299) or long-acting ESAs (darbepoetin and methoxy polyethylene glycol-epoetin β; n = 403)...

Erythropoiesis Stimulating Agents (ESAs) are well-tolerated and effective drugs for the treatment of anaemia in patients with chronic kidney disease. In the past, scientific research and clinical practice around ESAs have mainly focused on the haemoglobin target to reach, and to moving towards the normality range; more cautious approach has been taken more recently. However, little attention has been paid to possible differences among ESA molecules. Although they present a common mechanism of action on the erythropoietin receptor, their peculiar pharmacodynamic characteristics could give different signals of activation of the receptor, with possible clinical differences...

BACKGROUND: Erythropoietin-stimulating agents (ESAs) are used to treat anemia in patients with chronic kidney disease, enabling maintenance of stable hemoglobin levels and eliminating the need for multiple transfusions. Epoetin-beta pegol (C.E.R.A.) is a continuous erythropoietin receptor activator created by integrating a large methoxy-polyethylene-glycol-polymer chain into the erythropoietin molecule, which provides it with a longer half-life. On rare occasions, cases of antibody-mediated pure red cell aplasia (PRCA) related to ESAs are reported...

Introduction: Anemia in patients with chronic kidney disease (CKD) is present in about 50% in pre-dialysis and over 90% of patients on hemodialysis. Erythropoiesis-stimulating agent (ESA) is a standard therapy for renal anemia, but management of anemia in CKD still remains a challenge from the treatment point of view. Aim: To evaluate safety and efficacy of methoxy polyethylene glycol-epoetin beta as continuous erythropoietin receptor activator (C.E.R.A.) in maintenance of haemoglobin (Hb) concentrations in patients with chronic renal anemia in the routine clinical practice...

Pre-existing antibodies that bind polyethylene glycol are present in about 40% of healthy individuals. It is currently unknown if pre-existing anti-polyethylene glycol (PEG) antibodies can alter the bioactivity of pegylated drugs with a single long PEG chain, which represents the majority of newly developed pegylated medicines. Methoxy polyethylene glycol-epoetin beta (PEG-EPO) contains a single 30 kDa PEG chain and is used to treat patients suffering from anemia. We find that the pre-existing human anti-PEG IgM and IgG antibodies from normal donors can bind to PEG-EPO...

AIMS: Methoxy polyethylene glycol-epoetin beta (continuous erythropoietin receptor activator, C.E.R.A.) is used for the treatment of anaemia in adults with chronic kidney disease (CKD). Patients treated with shorter-acting erythropoiesis-stimulating agents, up to three-times weekly, can be switched to once-monthly C.E.R.A. Doses can be adjusted on a monthly basis based on haemoglobin levels during the preceding period. A model-based approach was applied to optimise C.E.R.A. development, more specifically, the confirmatory trial of the paediatric plan...

BACKGROUND AND OBJECTIVES: Erythropoiesis-stimulating agents correct anemia of CKD but may increase cardiovascular risk. We compared cardiovascular outcomes and all-cause mortality associated with monthly methoxy polyethylene glycol-epoetin beta with those of the shorter-acting agents epoetin alfa/beta and darbepoetin alfa in patients with anemia of CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted a multicenter, open-label, noninferiority trial in which patients were randomized to receive methoxy polyethylene glycol-epoetin beta or reference erythropoiesis-stimulating agents, stratified by maintenance or correction treatment status and C-reactive protein level...

Objectives: There is a lack of data in Panama on the potential differences in total healthcare professional (HCP) time between routine administrations of short-acting erythropoietin simulating agents (ESAs) (i.e. epoetin alfa) and continuous erythropoietin receptor activator (CERA) (i.e. methoxy polyethylene glycol-epoetin beta). This study aimed to quantify the HCP time associated with a single administration of epoetin alfa and CERA for the treatment of anemic patients with chronic kidney disease (CKD) on hemodialysis...

BACKGROUND: Clinicians providing dialysis care have numerous erythropoiesis-stimulating agents (ESAs) available for treating anemia. We sought to provide a contemporary description of ESA types used in hemodialysis (HD) settings in nine European countries. METHODS: Our study uses Dialysis Outcomes and Practice Patterns Study phase 5 (2012-2015) data from nine European countries (Belgium, France, -Germany, Italy, Russia, Spain, Sweden, Turkey, and the United Kingdom)...

PURPOSE: to study efficacy of various schemes of therapy of patients with chronic heart failure (CHF) and anemia. MATERIALS AND METHODS: We included in this study 208 patients with CHF of ishemic etiology (mean age 60.6±1.4 years, 174 with and 34 without anemia). According to therapeutic regimen of the use of methoxy polyethylene glycol-epoetin beta (MEB, 0.60 mсg/kg) and intravenous (IV) iron hydroxide sucrose complex all patients were divided into 4 groups. In all patients before and after treatment we determined Hb, Ht, plasma levels of ferritin, erythropoietin (EPO), NT-proBNP, IL-1, IL-6, TNF-α, transferrin saturation (TS), total vascular peripheral resistance, and parameters of systolic and diastolic function of left ventricular (LV) myocardium (by echocardiography and doppler echocardiography)...
