Primary Outcome Measures:
  • Change From Baseline in Left Ventricular Mass Index (LVMI) Over 48 Weeks Measured by Cardiac Magnetic Resonance Imaging (MRI) [ Time Frame: Baseline, 24 Weeks, and 48 Weeks/Early Termination ] [ Designated as safety issue: No ]

    Change from Baseline in left ventricular mass index (LVMI) over 48 weeks measured by cardiac MRI. The effects of paricalcitol injection on progression or regression of left ventricular hypertrophy (LVH) in participants with Stage 5 chronic kidney disease (CKD) on hemodialysis (HD) compared to placebo. Left Ventricular Mass is normalized to the participant's height by the following equation to obtain LVMI: LVM (g) divided by height (m)2.7.

    The primary comparison was between the 4 mcg paricalcitol injection and the placebo treatment groups in the change from baseline to Week 48.



Secondary Outcome Measures:
  • Change From Baseline in the Echocardiographic Assessment of Diastolic Function Assessed by Evaluating Changes in Diastolic Mitral Annular Relaxation Velocity (E') Over 48 Weeks. [ Time Frame: Baseline, 24 Weeks, and 48 Weeks/Early Termination ] [ Designated as safety issue: No ]
    Mitral Annular relaxation velocity is a measure of diastolic heart function.

  • Change From Baseline in Evaluating Changes in the Additional Measure of Diastolic Function of Isovolumetric Relaxation Time (IVRT) Over 48 Weeks. [ Time Frame: Baseline, 24 Weeks, and 48 Weeks/Early Termination ] [ Designated as safety issue: No ]
    Isovolumetric relaxation time is a measure of diastolic heart function.

  • Change From Baseline in Evaluating Changes in the Additional Measure of Diastolic Function of Peak E-wave Velocity to Lateral E-wave Velocity (E/E') Over 48 Weeks. [ Time Frame: Baseline, Week 24, and Week 48/Early Termination ] [ Designated as safety issue: No ]
    The ratio of peak E-wave velocity to lateral e-wave velocity is a measure of diastolic heart function.

  • Change From Baseline in Evaluating Changes in the Additional Measure of Diastolic Function E-wave Deceleration Time (DT) Over 48 Weeks [ Time Frame: Baseline, 24 Weeks, and 48 Weeks/Early Termination ] [ Designated as safety issue: No ]
    E-wave deceleration time is a measure of diastolic heart function.

  • Change From Baseline in Biological Marker Triiodothyronine (T3). [ Time Frame: Baseline and Early Termination Visit (4 Weeks, 5 Weeks, 7 Weeks, 8 Weeks, 14 Weeks, and 16 Weeks) ] [ Designated as safety issue: No ]
    Plasma T3 is a circulating hormone that may have an effect on diastolic heart function and its level may be affected by treatment with paricalcitol. The study was terminated early (prior to any subject reaching Week 24). The values are for Baseline and Early Termination only. Each of the 12 randomized subjects terminated at different study weeks; therefore Early Termination cannot be defined as a specific week and varies for different subjects. Of the 12 subjects, 11 had early termination visits and 1 didn't. The final visit week range is 4-16.

  • Change From Baseline in Biological Marker Plasma Troponin-T Over 48 Weeks [ Time Frame: Baseline and Early Termination Visit (4 Weeks, 5 Weeks, 7 Weeks, 8 Weeks, 14 Weeks, and 16 Weeks) ] [ Designated as safety issue: No ]
    Plasma troponin-t is a marker of heart damage and and its level may be affected by treatment with paricalcitol. The study was terminated early (prior to any subject reaching Week 24). The values are for Baseline and Early Termination only. Each of the 12 randomized subjects terminated at different study weeks; therefore Early Termination cannot be defined as a specific week and varies for different subjects. Of the 12 subjects, 11 had early termination visits and 1 didn't. The final visit week range is 4-16.

  • Change From Baseline in Biological Marker Plasma Interleukin-6 (IL-6) Over 48 Weeks [ Time Frame: Baseline and Early Termination Visit (4 Weeks, 5 Weeks, 7 Weeks, 8 Weeks, 14 Weeks, and 16 Weeks) ] [ Designated as safety issue: No ]
    Plasma IL-6 is a biomarker of inflammation that may have an effect on heart function and its level may be affected by treatment with paricalcitol. The study was terminated early (prior to any subject reaching Week 24). The values are for Baseline and Early Termination only. Each of the 12 randomized subjects terminated at different study weeks; therefore Early Termination cannot be defined as a specific week and varies for different subjects. Of the 12 subjects, 11 had early termination visits and 1 didn't. The final visit week range is 4-16.

  • Change From Baseline in Biological Marker Plasma High Sensitivity C-reactive Protein (hsCRP) Over 48 Weeks [ Time Frame: Baseline and Early Termination Visit (4 Weeks, 5 Weeks, 7 Weeks, 8 Weeks, 14 Weeks, and 16 Weeks) ] [ Designated as safety issue: No ]
    Plasma high sensitivity CRP is a biomarker of inflammation that may have an effect on heart function and its level may be affected by treatment with paricalcitol. The study was terminated early (prior to any subject reaching Week 24). The values are for Baseline and Early Termination only. Each of the 12 randomized subjects terminated at different study weeks; therefore Early Termination cannot be defined as a specific week and varies for different subjects. Of the 12 subjects, 11 had early termination visits and 1 didn't. The final visit week range is 4-16.

  • Change From Baseline in Biological Marker Plasma B-Type Natriuretic Peptide (BNP) [ Time Frame: Baseline and Early Termination Visit (4 Weeks, 5 Weeks, 7 Weeks, 8 Weeks, 14 Weeks, and 16 Weeks) ] [ Designated as safety issue: No ]
    Plasma BNP is a product from the heart that becomes elevated with an enlarged heart and its level may be affected by treatment with paricalcitol. The study was terminated early (prior to any subject reaching Week 24). The values are for Baseline and Early Termination only. Each of the 12 randomized subjects terminated at different study weeks; therefore Early Termination cannot be defined as a specific week and varies for different subjects. Of the 12 subjects, 11 had early termination visits and 1 didn't. The final visit week range is 4-16.
