CHAARTED, ChemoHormonal Therapy versus Androgen Ablation Randomized Trial for Extensive Disease in Prostate Cancer; CI, confidence interval; HR, hazard ratio; GETUG, Groupe d’Etude des Tumeurs Urogenitales; NR, not reported.
Includes 550 standard of care (SOC) and docetaxel and 516 SOC and zoledronate and docetaxel.
The rate of grade 3/4 neutropenia decreased to 15% after an amendment to use prophylactic GCSF.
