Primary Outcome Measures:
  • The Percentage of Participants With of Hypercalcemia [ Time Frame: Anytime during the study through Week 53 ]
    The percentage of participants with an event of hypercalcemia, defined as at least 1 adjusted calcium > 11.5 mg/dL or at least 2 consecutive adjusted calcium >= 11.0 mg/dL during the 52 weeks of the study.

  • The Percentage of Participants With Hyperphosphatemia [ Time Frame: Anytime during the study through Week 53 ]
    The percentage of participants with an event of hyperphosphatemia, defined as at least 2 consecutive phosphorus >= 7.0 mg/dL during the 52 weeks of the study.


Secondary Outcome Measures:
  • The Mean Change in Intact Parathyroid Hormone (iPTH) [ Time Frame: From Baseline to Final Visit (which could occur anytime between study initiation and Week 53) ]
  • The Percentage of Participants With iPTH <= 180 pg/mL or >= 50% Decrease of iPTH at the Participant's Final Visit [ Time Frame: From Baseline to the participant's Final Visit (which could occur anytime between study initiation and Week 53) ]
  • The Percentage of Participants With 2 or More Decreases From Baseline in iPTH of >= 50% [ Time Frame: Anytime during the study from Baseline to the participant's final visit (which could occur anytime from study initiation to Week 53) ]
  • Change in Mean iPTH [ Time Frame: Every week from Baseline through Week 13 and every other week thereafter until Week 53 ]
  • Duration of 2 Consecutive Decreases in iPTH >= 50% [ Time Frame: From Baseline to the participant's Final Visit (which could occur anytime between study initiation and Week 53) ]
  • Duration of 2 Consecutive iPTH Values <= 180 pg/mL [ Time Frame: From Baseline to the participant's Final Visit (which could occur anytime between study initiation to Week 53) ]
  • The Percentage of Participants Whose Abnormal Baseline Alkaline Phosphatase Was Normalized at Final Visit [ Time Frame: From Baseline to the participant's Final Visit (which could occur anytime between study initiation and Week 53) ]
  • The Percentage of Participants Whose Abnormal Baseline Bone Specific Alkaline Phosphatase (BSAP) Was Normalized at Final Visit [ Time Frame: From Baseline to the participant's Final Visit (which could occur anytime between study initiation and Week 53) ]

Arms Assigned Interventions
Experimental: Paricalcitol 2 µg ± 1 µg
Study drug was administered 3 times per week (no more frequently than every other day) intravenously immediately before the completion of hemodialysis. The initial dosage was administered for 2 weeks, with subsequent dosage adjustment based on the subject's iPTH, calcium (adjusted), and phosphorus levels every 2 weeks. Total duration of treatment was 48 weeks in this study, combined with 12 weeks in the previous study, M10-309 (NCT00667576), for a total of 52 weeks of treatment.
Drug: Paricalcitol
Intravenous (IV) paricalcitol, 3 times weekly, immediately before completion of hemodialysis.

Detailed Description:
The first 12-week period in this study was a dose-response study reported as Study M10-309 (NCT00667576). Only subjects who completed 12 weeks in NCT00667576 were enrolled into this study (M10-312). Baseline in this study was the same as Baseline in NCT00667576. The duration of treatment in Study M10-312 was 40 weeks (for a total of 52 weeks, including NCT00667576).
