Terminated
Conditions
Hemodialysis
Chronic Kidney Disease Stage V
Registration Number
NCT01758289
Lead Sponsor
AbbVie (prior sponsor, Abbott)
Brief Summary

This study was designed to evaluate the effectiveness, safety, and impact on quality of life when paricalcitol (Zemplar® intravenous \[IV\]) is administered in Venezuelan patients on hemodialysis who are at risk of developing secondary hyperparathyroidism associated with stage V chronic kidney disease.

Exclusion Criteria
  • Subjects with severe hyperparathyroidism (parathyroid hormone [PTH] > 3000 pg/mL)
  • Subjects with hypercalcemia, adjusted according to serum albumin, hyperphosphatemia, or subjects with calcium-phosphorus product (Ca x P) ≥ 70
  • Known hypersensitivity and/or toxicity of vitamin D, its metabolites and/or other components of Zemplar® IV (paricalcitol)

Primary Outcome Measures
NameTimeMethod
Percentage of Participants Achieving at Least a 30% Reduction From Baseline in the Levels of Parathyroid Hormone (PTH) at the Final Study VisitBaseline Week 1 (Study Visit 1) to Week 24 (Final Study Visit)
Secondary Outcome Measures
NameTimeMethod
European Quality of Life 5 Dimensions (EQ-5D) Visual Analogue Scale (VAS) Scores At Baseline, Week 12, and Week 24Baseline Week 1 (Study Visit 1), Week 12 (Study Visit 3), Week 24 (Final Study Visit)

The EQ-5D questionnaire is an international, standardized, generic instrument for describing and valuing health status that is divided into 5 parameters that include mobility, self-care, usual activities, pain/discomfort, anxiety/depression and a VAS. For the VAS portion, health status is assessed by participants on a vertical, visual analog scale from 0 to 100 where the endpoints are labeled 'worst imaginable health state' (0) and 'best imaginable health state' (100).

European Quality of Life 5 Dimensions (EQ-5D) Parameters of Mobility, Self-Care, Usual Activities, Pain/Discomfort, and Anxiety/Depression At Baseline, Week 12, and Week 24Baseline Week 1 (Study Visit 1), Week 12 (Study Visit 3), Week 24 (Final Study Visit)

The EQ-5D questionnaire is an international, standardized, generic instrument for describing and valuing health status that is divided into 5 parameters that include mobility, self-care, usual activities, pain/discomfort, anxiety/depression and a visual analogue scale (VAS). For each parameter other than the VAS, participants are asked to indicate which of 5 statements (from 'no problem' to 'extreme problem') best describes their health state.

Number of Participants Achieving Parathyroid Hormone (PTH) Levels < 300 pg/mLBaseline to Week 12, Week 12 to Week 24

Participants who achieved PTH Levels \< 300 pg/mL between the first and third study visit (Baseline to Week 12) and the third and final study visit (Week 12 to Week 24).

Percentage of Participants With Hypercalcemia, Hyperphosphatemia and Elevations of Calcium-Phosphate Product (Ca x P) at Baseline, Week 12, and Week 24Baseline Week 1 (Study Visit 1), Week 12 (Study Visit 3), Week 24 (Final Study Visit)

Hypercalcemia was defined as a value of serum calcium (Ca) greater than or equal to 10.3 mg/dL.

Hyperphosphatemia was defined as a value of serum phosphorus (P) greater than or equal to 5.5 mg/dL.

Elevated Ca×P was defined as as greater or equal to 56.65 mg\^2/dL\^2, calculated as the result of multiplying the maximum values of calcium (10.3 mg/dL) and phosphorus (5.5 mg/dL).

Number of Participants Achieving PTH Level Reductions to < 300 pg/mL or 30% Below Baseline in 12 or 24 WeeksBaseline Week 1 (Study Visit 1) to Week 24 (Final Study Visit)

Number of participants achieving PTH level reductions to \< 300 pg/mL or 30% below Baseline in 12 weeks (Baseline to Week 12 or Week 12 to Week 24) or in 24 weeks (Baseline to Week 24).

Beck Depression Inventory (BDI) Scores At Baseline and Final Study VisitBaseline Week 1 (Study Visit 1), Week 24 (Final Study Visit)

BDI is a 21-item questionnaire, participant self-report rating inventory that measures characteristic attitudes and symptoms of depression. The range of scores is 0 to 63, with a higher value representing a worse outcome.
