Brief Summary:
To evaluate the effects of paricalcitol capsules on cardiac structure and function over 48 weeks in patients with Stage 3/4 chronic kidney disease (CKD) who had left ventricular hypertrophy (LVH).
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Chronic Kidney Disease Left Ventricular Hypertrophy | Drug: paricalcitol Drug: placebo | Phase 3 |
Patients who met the inclusion criteria and did not meet any of the exclusion criteria were randomized in a 1:1 ratio to each treatment group to receive paricalcitol capsules or placebo. A stratified randomization scheme was used to ensure balance among treatment groups with respect to country, gender, and baseline renin angiotensin-aldosterone system (RAAS) inhibitor use (yes/no).
Participants who completed the 48-Week Treatment Period could continue on in the ongoing Long-term Follow-up Period that was to last 18 months, with study visits at 6 months, 12 months and 18 months post Treatment Week 48 Visit. Participants did not receive study drug, nor were they to have undergone echocardiogram/MRI procedures during the Long-term Follow-up Period.

Experimental: Paricalcitol
Participants received paricalcitol capsules 2 µg once a day (two 1 µg paricalcitol capsules), for up to 48 weeks. Participants who completed the 48-week Treatment Period could continue in the Long-term Follow-up Period for an additional 18 months. Participants did not receive study drug during the Long-term Follow-up Period.

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 to 48 weeks ]The Central Cardiac MRI Core Laboratory (CCL) interpreted and analyzed all cardiac MRI data. Left Ventricular Mass (LVM) was normalized to the participant's height by the following equation to obtain LVMI: LVM (grams) divided by height (meters)^2.7.
Secondary Outcome Measures :
- Change in Diastolic Mitral Annular Relaxation Velocity (E') [ Time Frame: Baseline to 48 weeks ]Diastolic mitral annular relaxation velocity (lateral E wave velocity; E') is a measure of diastolic function.
- Change in Ratio of Peak E Wave Velocity to Lateral E Wave Velocity (E/E') [ Time Frame: Baseline to 48 weeks ]The ratio of peak E wave velocity to lateral E wave velocity (E/E') is a measure of diastolic function.
- Change in E-wave Deceleration Time (DT) [ Time Frame: Baseline to 48 weeks ]E-wave deceleration time (DT) is a measure of diastolic function.
- Change in Isovolumetric Relaxation Time (IVRT) [ Time Frame: Baseline to 48 weeks ]Isovolumetric relaxation time (IVRT) is a measure of diastolic function.
- Change in Left Atrial Volume [ Time Frame: Baseline to 48 weeks ]Left atrial volume is a measure of diastolic function.
- Change in Plasma Triiodothyronine (T3) [ Time Frame: Baseline to 48 weeks ]Plasma triiodothyronine (T3) is a biological and inflammatory marker.
- Change in Interleukin-6 (IL-6) [ Time Frame: Baseline to 48 weeks ]Interleukin-6 (IL-6) is a biological and inflammatory marker.
- Change in Troponin-T [ Time Frame: Baseline to 48 weeks ]Troponin-T is a biological and inflammatory marker.
- Change in B-type Natriuretic Peptide (BNP) [ Time Frame: Baseline to 48 weeks ]B-type natriuretic peptide (BNP) is a biological and inflammatory marker.
- Change in High Sensitivity C-reactive Protein (hsCRP) [ Time Frame: Baseline to 48 weeks ]High sensitivity C-reactive protein (hsCRP) is a biological and inflammatory marker.
- Change in Progression of Thoraco-abdominal Aortic Plaque Volume [ Time Frame: Baseline to 48 weeks ]Change from baseline to Week 48 in thoraco-abdominal aortic plaque volume.
- Change in Progression of Thoraco-abdominal Aortic Wall Volume [ Time Frame: Baseline to 48 weeks ]Change from baseline to Week 48 in thoraco-abdominal aortic wall volume
- Change in Progression of Aortic Compliance [ Time Frame: Baseline to 48 weeks ]Change from baseline to Week 48 in aortic compliance.
- Change in Progression of Left Ventricular End-systolic Volume Index [ Time Frame: Baseline to 48 weeks ]Change from baseline to Week 48 in left ventricular end-systolic volume index.
- Change in Progression of Left Ventricular End-diastolic Volume Index [ Time Frame: Baseline to 48 weeks ]Change from baseline to Week 48 in left ventricular end-diastolic volume index.
- Change in Progression of Left Ventricular Ejection Fraction [ Time Frame: Baseline to 48 weeks ]Change from baseline to Week 48 in left ventricular ejection fraction.
