Patients with lower-risk myelodysplastic syndromes (MDS) are mainly affected by chronic anemia and fatigue. Treatment strategies aim to improve anemia and quality of life, as well as iron overload due to red blood cell transfusion support. To promote proliferation and differentiation of erythropoiesis, erythropoiesis-stimulating agents (ESAs) such as erythropoietin (EPO) and mimetics are applied as first-line therapy in a large fraction of lower-risk MDS patients. In general, ESAs yield favorable responses in about half of the patients, although responses are often short-lived...

Luspatercept (ACE-536, ACVR2B-Fc), a fusion protein consisting of the extracellular domain of ActRIIB receptor and the Fc-part of human immunoglobulin G1 (IgG1), is currently under clinical development (Phase III). It stimulates the formation of red blood cells and hence may be misused by athletes for doping purposes in the future. Several antibody-based strategies for the detection of Luspatercept and other ACVR2B-Fc fusion proteins in human serum were evaluated (ELISA; IEF-, SDS-, and SAR-PAGE followed by Western blotting; immunoprecipitation)...

BACKGROUND: Myelodysplastic syndromes are characterised by ineffective erythropoiesis. Luspatercept (ACE-536) is a novel fusion protein that blocks transforming growth factor beta (TGF β) superfamily inhibitors of erythropoiesis, giving rise to a promising new investigative therapy. We aimed to assess the safety and efficacy of luspatercept in patients with anaemia due to lower-risk myelodysplastic syndromes. METHODS: In this phase 2, multicentre, open-label, dose-finding study (PACE-MDS), with long-term extension, eligible patients were aged 18 years or older, had International Prognostic Scoring System-defined low or intermediate 1 risk myelodysplastic syndromes or non-proliferative chronic myelomonocytic leukaemia (white blood cell count <13 000/μL), and had anaemia with or without red blood cell transfusion support...

Regular transfusion and iron chelation are the current treatment of severe forms of thalassemia. As a consequence of this demanding supportive treatment, there are several unmet therapeutic needs. Due to a deeper understanding in the pathophysiology of thalassemia, new therapeutic strategies have been developed that are now in pre-clinical and clinical trials. Areas covered: Activin receptor ligand traps (luspatercept and sotatercept), drugs targeting ineffective erythropoiesis, showed encouraging results in Phase I and II clinical trials...

Erythropoiesis-stimulating agents (ESAs) are not perfect, since they have potential side effects. Iron therapy is also receiving growing attention in recent years. Areas covered: We performed a literature search on PubMed using the following key words: anemia, chronic kidney disease, HIF stabilisers, sotatercept, actin traps, iron, iron-containing phosphate binders, iron dialysate. We reviewed new drugs that are under clinical development to obtain better safety and activity and/or easier and cheaper manufacturing processes in comparison to available ESAs...

Patients with lower-risk myelodysplastic syndromes (MDS) are affected primarily by symptoms of chronic anemia and fatigue rather than progression to acute myeloid leukemia. Severe thrombocytopenia, although less common in lower-risk MDS, is associated with increased risk of bleeding. For anemic patients, the principal aim of treatment is to improve anemia and decrease red blood cell transfusions. For transfusion-dependent patients with lower-risk MDS without chromosome 5q deletion [non-del(5q) MDS], there are limited effective treatments...

INTRODUCTION: The main pillars for the treatment of chronic kidney disease (CKD) associated anemia are peptidic erythropoiesis stimulating agents (ESAs) and iron preparations. Both approaches benefit from long-term efficacy and safety data but are surrounded by clinical and economic concerns, driving the search for novel anti-anemic drugs. AREAS COVERED: By answering pivotal questions, the authors describe the recent developments of next generation ESAs, introduce cutting-edge iron formulations and focus on investigational approaches that interact with pathways involved in erythropoietin (Epo) synthesis and myeloid hematopoiesis...
