About this study

Official title: A Multi Centre, Open Label, Parallel Group, Randomized Controlled Trial to Compare the Safety and Efficacy of Oral Paricalcitol Versus Oral Calcitriol in the Treatment of Secondary Hyperparathyroidism in Dialysis Patients

The purpose of this study is to determine whether oral paricalcitol is safer and more efficacious compared to oral calcitriol in the treatment of hyperparathyroidism in chronic kidney disease patients undergoing dialysis.

Read the detailed description

Secondary hyperparathyroidism, a common consequence of chronic kidney disease, results from abnormal regulation of calcium and phosphate homeostasis. The early administration of calcium supplements or vitamin D attenuates the development and progression of hyperparathyroidism, preventing or retarding the emergence of many of the serious complications of chronic kidney disease. However, these vitamin D derivatives also have serious side effects, including hypercalcemia and hyperphosphatemia and, as a result, a high level of the calcium-phosphate product. These adverse outcomes have prompted the development of novel, "nonhypercalcemic" vitamin D analogues. Three of these analogues have recently been marketed for clinical use in patients with chronic kidney disease: 19-nor-1,25-dihydroxyvitamin D2 (paricalcitol), 1 -hydroxyvitamin D2 (doxercalciferol), and 22-oxacalcitriol.

Oral paricalcitol was developed to provide a convenient, alternative therapy, particularly for Peritoneal Dialysis patients in whom regular intravenous administration of paricalcitol is not practical. This study is designed to determine the proportion of patients with 'End stage renal failure' on haemodialysis or peritoneal dialysis and secondary hyperparathyroidism who achieved more than 30% reduction in baseline iPTH concentration at 24 weeks of treatment with Paricalcitol or Calcitriol capsules.

Questions about this trial

What is this clinical trial studying?

A study testing Paricalitol and Calcitriol in people with Hyperparathyroidism and Kidney Disease, run by Penang Hospital, Malaysia at 11 sites in Malaysia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Dec 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in Malaysia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

More than 30% reduction in baseline iPTH concentration at 24 weeks of treatment with Paricalcitol or Calcitriol capsules. (time frame: 24 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00800358, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Dec 2012.
