Brief Summary:
This observational study will evaluate the clinical benefit of Zemplar (paricalcitol injection) in daily routine practice in end-stage renal disease patients with severe over-reactivity of parathyroid glands. Participants will be followed for 6 months. Data will be collected from participants initiated on Zemplar therapy according to standard of care. The time to achieving the maintenance dose of Zemplar (paricalcitol injection), the proportion of participants achieving target parathyroid hormone levels, and prevalence of elevated serum calcium and phosphate levels will be evaluated.

Condition or disease
Kidney Failure, Chronic

Detailed Description:
Prospective data collection started at initial dosing with Zemplar (paricalcitol injection) and ended up to 6 months later. If available, retrospective data on vitamin D treatment as well as on the incidence of hypercalcaemia and hyperphosphataemia in the 6 months leading up to paricalcitol treatment were also collected. Eight visits were planned for documentation of prospective data. In accordance with the non-interventional character of the study, only diagnostic and monitoring procedures were applied which are part of the routine medical care of secondary hyperparathyroidism.

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Time (in Weeks) From Treatment Initiation to Achieving Maintenance Dose of Zemplar (Paricalcitol Injection) [ Time Frame: 6 months ]
    Maintenance dose is defined as weekly dose of paricalcitol that results in at least 2 consecutive intact parathyroid hormone (iPTH) values within the target therapeutic range of 150 - 300 pg/mL, corresponding to 15.9 - 31.8 pmol/L.


Secondary Outcome Measures :
  1. Number of Participants Achieving Target Intact Parathyroid Hormone (iPTH) Levels at Month 6 [ Time Frame: 6 months ]
    Target intact parathyroid hormone (iPTH) values were within the target therapeutic range of 150 - 300 pg/mL, corresponding to 15.9 - 31.8 pmol/L.

  2. Country-Specific Data on the Usage of Medication Affecting Calcium (Ca) Balance [ Time Frame: 6 months prior to start of study through 6 months of treatment ]
    If available, data on vitamin D treatment (those who received vitamin D supplement products from Anatomical Therapeutic Chemical [ATC] group A11CC [vitamin D and analogues]) in the 6 months leading up to paricalcitol treatment and during 6 months of paricalcitol treatment were also collected.

  3. Country-Specific Data on the Usage of Medication Affecting Phosphorus (P) Balance [ Time Frame: 6 months prior to start of study through 6 months of treatment ]
    If available, data on the use of phosphate binders (those who received calcium-based phosphate binders or sevelamer/lanthanum) in the 6 months leading up to paricalcitol treatment and during 6 months of paricalcitol treatment were also collected.

  4. Country-Specific Data on the Usage of Medication Affecting Secondary Hyperparathyroidism [ Time Frame: 6 months prior to start of study through 6 months of treatment ]
    If available, data on the use of medication affecting secondary hyperparathyroidism (those who received calcimimetics and calcium supplementation) in the 6 months leading up to paricalcitol treatment and during 6 months of paricalcitol treatment were also collected.

  5. Number of Participants With Hypercalcaemia During Preceding 6 Months of Conventional Vitamin D Therapy [ Time Frame: 6 months prior to start of study through baseline ]
    Hypercalcaemia (serum calcium > 2.6 mmol/L) among participants during the preceding 6 months of conventional vitamin D therapy was derived from retrospective data collection in case report form, reported at baseline. Conventional vitamin D therapy included vitamin D supplement products from ATC group A11CC (vitamin D and analogues).

  6. Number of Participants With Hypercalcaemia During 6 Months of Selective Vitamin D Receptor Activator (Paricalcitol) Treatment [ Time Frame: 6 months ]
    Hypercalcaemia (serum calcium > 2.6 mmol/L), based on laboratory data, was collected during the observed 6 months treatment with Zemplar (paricalcitol injection).

  7. Number of Participants With Hyperphosphataemia During Preceding Conventional Vitamin D Therapy [ Time Frame: 6 months prior to start of study through baseline ]
    Hyperphosphataemia (serum phosphorus >1.78 mmol/L) among participants during the preceding 6 months of conventional vitamin D therapy was derived from retrospective data collection in case report form, reported at baseline. Conventional vitamin D therapy included vitamin D supplement products from ATC group A11CC (vitamin D and analogues).

  8. Number of Participants With Hyperphosphataemia During 6 Months of Selective Vitamin D Receptor Activator (Paricalcitol) Treatment [ Time Frame: 6 months ]
    Hyperphosphataemia (serum phosphorus > 1.78 mmol/L), based on laboratory data, was collected during the observed 6 months treatment with Zemplar (paricalcitol injection).
