Primary Outcome Measures:
  • Percent change in iPTH from baseline during the efficacy period [ Time Frame: Baseline, 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Proportion of subjects with ≥ 30% reduction in iPTH from baseline during the efficacy period [ Time Frame: Baseline, 12 weeks ] [ Designated as safety issue: No ]
  • Proportion of subjects with iPTH ≤ 300 pg/mL during the efficacy period [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Mean change in corrected calcium and phosphorus from baseline during the efficacy period [ Time Frame: Baseline, 12 weeks ] [ Designated as safety issue: Yes ]
