Outcomes
Primary Outcome Measures
To evaluate the efficacy of AMG 073 compared with placebo by determining the proportion of subjects with a mean intact parathyroid hormone (iPTH) value <= 250 pg/mL (26.5 pmol/L) during the efficacy assessment phase.
Secondary Outcome Measures
To evaluate the efficacy of AMG 073 compared with placebo by determining: the proportion of subjects with a reduction from baseline in iPTH of >= during the efficacy assessment phase
To evaluate the efficacy of AMG 073 compared with placebo by determining: percentage change from baseline in calcium x phosphorus (Ca x P) during the efficacy assessment phase
To evaluate the efficacy of AMG 073 compared with placebo by determining: changes in self-reported cognitive function from baseline to the end of the efficacy assessment phase
To evaluate the safety of AMG 073 compared with placebo.
