Paris--Adding a form of high-dose calcitriol to docetaxel (Taxotere) offers improved survival over docetaxel alone in men with metastatic androgen-independent prostate cancer, according to results of a multicenter trial presented at the 13th European Cancer Conference (ECCO-13) here. Further, the addition of the calcitriol formulation, known as DN-101, to the chemotherapy agent produced an unanticipated advantage in a reduced number of serious gastrointestinal and thromboembolic adverse events.
