FDA Orphan Status for Keros Duchenne Candidate

FDA has granted Keros Therapeutics an orphan drug designation for its investigational therapy KER-065 and its use in treating Duchenne muscular dystrophy. The company says it is preparing to launch a Phase 2 trial of the therapy.

Keros describes KER-065 as a ligand trap designed to block signaling pathways involving myostatin and activin A, proteins that limit muscle growth and repair. By inhibiting these pathways, the company hopes the drug can boost skeletal muscle regeneration, increase strength, reduce fibrosis, and improve bone health.

Alongside KER-065, Keros says it also developing elritercept for treating cytopenias such as anemia and thrombocytopenia in patients with blood disorders, including myelodysplastic syndrome and myelofibrosis.
