Vantictumab /vænˈtɪktʊmæb/ is a human IgG2 monoclonal antibody designed for the treatment of cancer.^[1]

This drug was developed by OncoMed Pharmaceuticals Inc. in partnership with Bayer.^[2] OncoMed was awarded a patent in 2016, which is set to expire in 2029.^[3] In April 2017, Bayer terminated its option to license vantictumab.^[4]

It inhibits wnt signalling by targeting the frizzled receptors on cancer cells.^[5]

Phase I trials have been completed for pancreatic cancer, non-small cell lung cancer, and breast cancer. In 2016 results were reported from a phase 1b clinical trial for triple-negative breast cancer^[5]^[6] and in 2020 for pancreatic cancer.^[7]
