Takeda Oncology (originally Millennium Pharmaceuticals) is a biopharmaceutical company based in Cambridge, Massachusetts. It is a fully owned subsidiary of Takeda Pharmaceutical. Takeda Oncology's research, development and commercialization activities focused in two therapeutic areas: oncology and inflammation to develop a line of new product candidates. It was one of the first companies to systematically search for genes linked to disease, although none of the drugs which it is marketing or has in clinical trial, with one partial exception, have been the results of that research.
