"This agreement enables us to strategically expand our program, subsidized by non-dilutive capital, while also gaining access to one of the largest pharmaceutical markets globally."

Yuan Sun, Executive Director of Hansoh Pharma, added, "We are excited to partner with Keros, a leader in understanding the role of the Transforming Growth Factor-Beta family of proteins. We believe in the potential of KER-050 as a treatment for diseases associated with ineffective hematopoiesis, such as myelodysplastic syndromes and other hematologic disorders, and we believe that our extensive clinical development and commercialization experience in China can help to bring this differentiated product candidate to benefit patients across China."

Keros will receive a $20 million upfront payment and will also be eligible to receive up to $170.5 million in development and commercial milestones, plus tiered royalties on net product sales ranging from the low double digit to high teens.

About KER-050

Keros’ lead protein therapeutic product candidate, KER-050, is an engineered ligand trap comprised of a modified ligand-binding domain of the Transforming Growth Factor-Beta receptor known as activin receptor type IIA that is fused to the portion of the human antibody known as the Fc domain. KER-050 is being developed for the treatment of low blood cell counts, or cytopenias, including anemia and thrombocytopenia, in patients with myelodysplastic syndromes, or MDS, and in patients with myelofibrosis.
