Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 75 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Chronic hemodialysis patients with severe SHPT (defined as iPTH ≥ 800pg/mL) resistant to rocaltrol or alfacalcidol (defined as iPTH not controlled in the range between 2 - 9 times of lab upper limit reference).
  • Chronic hemodialysis patients with severe SHPT and at the same time hypercalcemia (defined as serum calcium ≥2.56mmol/L) but still < 2.8mmol/L precluding the use of rocaltrol or alfacalcidol but still feasible to use paricalcitol.

Who cannot join

About this study

Official title: Providing Intravenous Paricalcitol Treatment to the Sick and Poor Chronic Hemodialysis Patients With Severe Secondary Hyperparathyroidism Resistant to Existing Vitamin D Analogs

This study aims to provide intravenous paritcalcitol treatment for the sick and poor hemodialysis patients with severe secondary hyperparathyroidism (SHPT) resistant to existing vitamin D analogs therapy or with hypercalcemia precluding the use of existing vitamin D analogs.

The study aims to evaluate the effect of paricalcitol on control of SHPT, biochemical parameters of chronic kidney disease-mineral bone disease, cardiac parameters, vascular calcification and stiffness parameters and nutrition status in patients receiving chronic hemodialysis treatment.

Read the detailed description

This is a 2-year single-arm intervention study of which intravenous paricalcitol will be provided as a second-line treatment to 30 chronic hemodialysis patients with severe SHPT (defined as intact parathyroid hormone [iPTH] ≥ 800pg/mL) resistant to existing vitamin D analogs treatment (including rocaltrol and alfacalcidol) or with hypercalcemia (defined as serum calcium ≥2.56mmol/L) precluding the use of existing vitamin D analogs.

The study aims to evaluate the control of SHPT, various biochemical parameters of chronic kidney disease-mineral bone disease, left ventricular mass and volumes, vascular calcification and stiffness parameters, handgrip strength and serum albumin with the use of intravenous paricalcitol in patients receiving chronic hemodialysis treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Intravenous ParicalcitolDrug

    Also called Zemplar

    Twenty four months of intravenous paricalcitol will be given twice or thrice weekly post-hemodialysis depending on frequency of hemodialysis of the patients

Study groups in NCT03023748
Study groupRoleWhat they receive
intravenous paricalcitol solutionsExperimentalIntravenous paricalcitol will be administered twice or thrice weekly post-hemodialysis with a dose based on the baseline iPTH level divided by 120. For instance, with a baseline iPTH 1200pg/mL, an induction dose of 10mcg twice or thrice weekly will be given. The maximum weekly dose allowed is 30mcg. Subsequent dose titration may be required depending on the serum PTH level. Intravenous paricalcitol will be continued up to 24 months.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Intravenous Paricalcitol in people with Endstage Renal Disease and Secondary Hyperparathyroidism, run by The University of Hong Kong at 1 site in Hong Kong.

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 2 inclusion and 2 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: status not confirmed, as of the sponsor's last update on 18 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Hong Kong. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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?

Change in left ventricular mass index (time frame: 52 weeks and 104 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 18 Jan 2017.
