简要总结
This is an open-label, multicenter, Phase 1/2 study of TAK-700 in combination with docetaxel and prednisone that will evaluate the safety and pharmacokinetics (PK) of the combination and will allow estimation of prostate-specific antigen (PSA) response in men with metastatic castration-resistant prostate cancer (mCRPC).
