Primary Outcome Measures:
  • Achieving the NKF-K/DOQI targets for both biPTH (80-160 pg/mL, equivalent to iPTH 150-300 pg/mL) and Ca x P (less than 55 mg^2/dL^2) during the assessment phase [ Time Frame: Weeks 17 - 27 ]
    Proportion of subjects in each treatment group simultaneously achieving the National Kidney Foundation - Kidney Disease Outcome Quality Initiative (NKF-K/DOQI) targets for both biPTH (80-160 pg/mL, equivalent to iPTH 150-300 pg/mL) and Ca x P (< 55 mg^2/dL^2) during the assessment phase (last 11 weeks of study following a 16-week titration phase)


Secondary Outcome Measures:
  • Absolute Change from Baseline for P During the Assessment Phase [ Time Frame: Baseline to weeks 17-27 ]
    Absolute change from baseline for serum phosphorus (P) during the assessment phase

  • Proportion of Participants with ≥ 30% Reduction from Baseline in Mean iPTH During the Assessment Phase [ Time Frame: Baseline and Weeks 17-27 ]
    Proportion of participants with ≥ 30% reduction from baseline in mean intact parathyroid hormone (iPTH) during the assessment phase.

  • Percent Change from Baseline for Calcium During the Assessment Phase [ Time Frame: Baseline to weeks 17-27 ]
    Percent Change from Baseline for Calcium (Ca) During the Assessment Phase

  • Percent Change from Baseline for Phosphorus During the Assessment Phase [ Time Frame: Baseline to weeks 17-27 ]
    Percent change from baseline for Phosphorus (P) during the assessment phase

  • Percent Change from Baseline for Ca x P During the Assessment Phase [ Time Frame: Baseline to weeks 17-27 ]

  • Percent Change from Baseline for iPTH During the Assessment Phase [ Time Frame: Baseline to weeks 17-27 ]
    Percent change from baseline for intact parathyroid hormone (iPTH) during the assessment phase

  • Proportion of Participants who Attained the K/DOQI Target Range for Ca x P During the Assessment Phase. [ Time Frame: Weeks 17 - 27 ]
    Proportion of participants who attained the K/DOQI target range for calcium x phosphorus (Ca x P) during the assessment phase.

  • Proportion of Participants who Attained the K/DOQI Target Range for Ca During the Assessment Phase [ Time Frame: Weeks 17-27 ]
    Proportion of participants who attained the K/DOQI target range for calcium (Ca) during the assessment phase.

  • Proportion of Participants who Attained the K/DOQI Target Range for iPTH During the Assessment Phase [ Time Frame: Weeks 17-27 ]
    Proportion of participants who attained the K/DOQI target range for intact parathyroid hormone (iPTH) during the assessment phase.

  • Proportion of Participants who Attained the K/DOQI Target Range for P During the Assessment Phase. [ Time Frame: Weeks 17-27 ]
    Proportion of participants who attained the K/DOQI target range for phosphorus (P) during the assessment phase.

  • Absolute Change from Baseline for iPTH During the Assessment Phase [ Time Frame: Baseline to weeks 17-27 ]
    Absolute change from baseline for intact parathyroid hormone (iPTH) during the assessment phase.

  • Absolute Change from Baseline for Ca During the Assessment Phase [ Time Frame: Baseline to weeks 17-27 ]
