Pre-Made Bintrafusp Alfa Biosimilar, Fusion Protein targeting CD274/PD-L1 fused with human TGFBR2 (transforming growth factor beta receptor 2) (1:2) via a peptidyl linker: Recombinant therapeutic protein targeting B7-H/B7H1/PDCD1L1/PDCD1LG1 is a biosimilar expressed by mammalian cell line as a benchmark reference therapeutic antibody for biological drug disovery items including cell culture, assay development, animal model development, PK/PD model development (Pharmacokinetics & Pharmacodynamic) and mechanism of action (MOA) research.
Bintrafusp alfa (M7824) is a bifunctional fusion protein composed of the extracellular domain of the human TGF-¦Â receptor II (TGF-¦ÂRII or TGF-¦Â ¡®trap¡¯) fused via a flexible linker to the C-terminus of each heavy chain of an IgG1 antibody blocking PD-L1 (anti-PD-L1). Bintrafusp alfa is more effectively suppressed tumor growth and metastasis than either a TGF-¦Â trap or an anti-PD-L1 antibody alone. Bintrafusp alfa also inhibited spontaneous metastasis in multiple preclinical models, presumably due to its suppressive effect on epithelial-to-mesenchymal transition
