NCIt definition : A fully human, IgG2 monoclonal antibody directed against activin-like receptor kinase
1 (ALK-1) with potential antineoplastic activity. Ascrinvacumab binds to and neutralizes
ALK-1. This may disrupt tumor endothelial cell function and inhibit tumor angiogenesis,
eventually leading to an inhibition of tumor cell proliferation. ALK-1, a member of
the transforming growth factor beta (TGF-b) type I receptor family, is overexpressed
on endothelial cells in a variety of tumor cell types and increases endothelial cell
proliferation and migration.;
