                                        Comment: The INN record for ulenistamab identifies this as a hunamised monoclonal antibody directed against a protein called pancreatic adenocarcinoma up-regulated factor (PAUF). PAUF appears to be a product of the zymogen granule protein 16B gene ZG16B (UniProt accession Q96DA0), that is aberrantly expressed in some cancers [1,4], and which is involved in tumour development and metastasis [2]. The peptide sequences of the heavy and light chains of ulenistamab are claimed in patent WO2019022281A1 [3].
