A Phase 2, Open-Label, Ascending Dose Study of KER-050 for the Treatment of Anemia in Patients With Very Low, Low, or Intermediate Risk Myelodysplastic Syndromes (MDS)

Description

The purpose of this study is to evaluate the effects of KER-050 on anemia in patients with very low, low or intermediate risk MDS.KER-050 is a therapeutic protein designed to increase red blood cell and platelet production by inhibiting the signaling of a subset of the transforming growth factor beta (TGF-ß) family of proteins to promote hematopoiesis. It is being developed for the treatment of low blood cell counts, or cytopenias including anemia and thrombocytopenia in patients with Myelodysplastic Syndrome (MDS) and Myelofibrosis (MF).
