ALK1 antagonists and their uses in treating renal cell carcinoma

摘要

In certain aspects, the present disclosure relates to the insight that a polypeptide comprising a ligand-binding portion of the extracellular domain of activin-like kinase I (ALK1) polypeptide may be used to inhibit tumor growth of renal cell carcinoma (RCC) in vivo. In additional aspects the disclosure relates to the insight that a polypeptide comprising a ligand-binding portion of the extracellular domain of ALK1 dramatically increases the ability of a standard of care receptor tyrosine kinase inhibitor to inhibit RCC tumor growth in vivo.
