Preclinical efficacy of the Wnt/β-catenin pathway inhibitor BC2059 for the treatment of desmoid tumors.

ABSTRACT: Mutation in the CTNNB1 gene, leading to a deregulation of the WTN/β-catenin pathway, is a common feature of desmoid tumors (DTs). Many β-catenin inhibitors have recently been tested in clinical studies; however, BC2059 (also referred as Tegavivint), a selective inhibitor of nuclear β-catenin that works through binding TBL-1, is the only one being evaluated in a clinical study, specifically for treatment of desmoid tumor patients. Preclinical studies on BC2059 have shown activity in multiple myeloma, acute myeloid leukemia and osteosarcoma. Our preclinical studies provide data on the efficacy of BC2059 in desmoid cell lines, which could help provide insight regarding antitumor activity of this therapy in desmoid tumor patients. In vitro activity of BC2059 was evaluated using desmoid tumor c
