TAK-700 Development Halted Due to Poor Phase III Trial Results.

Takeda Oncology Company and Millenium announced recently that they are halting the development of TAK-700 (Ortoronel) due to poor Phase III trial results in men with metastatic prostate cancer who have not had previous chemotherapy. The drug failed to extend survival time. TAK-700 has been previously discussed in blogs published on this website on June 3rd and November 21st, 2011. TAK-700 is an oral, non-steroidal, androgen (e.g. testosterone) synthesis inhibitor. End points of the clinical studies also included delay in disease progression in addition to extending survival time.
