Primary Outcome Measures:
  • Reduction in Mean iPTH of ≥ 30% During the Efficacy Assessment Phase [ Time Frame: Efficacy assessment phase (weeks 12-18) ] [ Designated as safety issue: No ]
    Reduction in mean intact parathyroid hormone (iPTH) of ≥ 30% within the participant during the efficacy assessment phase


Secondary Outcome Measures:
  • Percentage Change From Baseline in Mean iPTH During the Efficacy Assessment Phase [ Time Frame: Baseline, efficacy assessment phase (weeks 12-18) ] [ Designated as safety issue: No ]
    Percentage change from baseline in mean intact parathyroid hormone (iPTH) during the efficacy assessment phase
