About The Company
At Keros, our mission is to innovate therapies that have the potential to shift the treatment paradigm for a wide range of patients with disorders that are linked to dysfunctional signaling of the transforming growth factor-beta (TGF-ß) family of proteins.
About the Role

At Keros, our mission is to deliver significant clinical benefit to a wide range of patients with disorders that are linked to dysfunctional signaling of the transforming growth factor-beta (TGF-ß) family of proteins. With a focus on developing differentiated product candidates that are designed to alter TGF-β signaling, we aim to target the pathways critical for the growth, repair and maintenance of blood cells and a number of tissues, including bone, skeletal muscle, adipose and heart tissue. We believe our product candidates have the potential to unlock the full therapeutic benefits of modulating the TGF-β superfamily and provide disease-modifying benefit to patients.
