Approved drug
olaratumab is an approved drug (EMA & FDA (2016))
Compound class: Antibody
Comment: Olaratumab is a fully human anti-platelet-derived growth factor receptor α (PDGFRα) monoclonal antibody, developed by Eli Lilly (link to Lilly's olaratumab webpage here), originally developed by ImClone Systems, Inc. [2].
Peptide sequences and structural information for this antibody are available from its IMGT/mAb-DB record. BLAST peptide sequence analysis reveals identical matches with sequences 8 and 16 from patent US8128929, and directly to clone IMC-3G3 [1]. From patent US8128929 it appears that the epitope recognised by olaratumab overlaps the PDGFRα binding sites for PDGF-AA and PDGF-BB.
