Tanomastat (previously known as BAY 12-9566) is an inhibitor of angiogenesis and a biphenyl matrix metalloprotease (MMP). The drug was selective towards MMPs 2,3, and 9 and no activity against MMP1. Tanomastat was developed for the treatment of cancer and arthritis. Tanomastat participated in phase III clinical trials as maintenance therapy in patients with advanced ovarian cancer, and in patients with pancreatic, lung cancers. However, all studied were discontinued after the recommendation of the independent data safety monitoring board.
