Keros Therapeutics, Inc.
Business
Keros Therapeutics is a clinical-stage biopharmaceutical company developing protein therapeutics targeting transforming growth factor-beta (TGF-β) signaling pathways for neuromuscular and hematological disorders. Its lead candidates are rinvatercept (KER-065) for neuromuscular diseases including Duchenne muscular dystrophy and amyotrophic lateral sclerosis, and elritercept (KER-050) for cytopenias in myelodysplastic syndromes and myelofibrosis. The company operates two franchises—neuromuscular and hematology—with rinvatercept in Phase 2 development and elritercept in Phase 3 trials; in December 2024, Keros licensed elritercept globally (excluding mainland China, Hong Kong and Macau) to Takeda Pharmaceuticals for further development and commercialization.
