Primary outcomes

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.

Time frame: Efficacy Assessment phase - final 10 weeks of study

Secondary outcomes

To evaluate the efficacy of AMG 073 compared with placebo by determining: the proportion of subjects with a reduction from baseline in mean iPTH of >= 30% during the efficacy assessment phase

Time frame: Efficacy Assessment phase - final 10 weeks of study
To evaluate the efficacy of AMG 073 compared with placebo by determining: percentage change from baseline in iPTH during the efficacy assessment phase

Time frame: Efficacy Assessment phase - final 10 weeks of study
To evaluate the safety of AMG 073 compared with placebo

Time frame: Entire study - 26 weeks
