Trial summary

Secondary hyperparathyroidism (sHPT) is common in patients with chronic kidney disease (CKD), including those who are undergoing long-term haemodialysis treatment. sHPT is characterized by persistently elevated levels of parathyroid hormone (PTH) and major disturbances in phosphorus and calcium metabolism.

About this study

Official title: Efficacy and Safety of High Intensity Focused Ultrasound (HIFU) Device to Treat Uncontrolled Secondary Hyperparathyroidism in Chronic Haemodialysis Patients

Secondary hyperparathyroidism (sHPT) is common in patients with chronic kidney disease (CKD), including those who are undergoing long-term haemodialysis treatment. sHPT is characterized by persistently elevated levels of parathyroid hormone (PTH) and major disturbances in phosphorus and calcium metabolism. When glomerular filtration rate (GFR) falls, the phosphorus clearance decreases significantly, leading to phosphorus retention. The resulting hyperphosphatemia is thought to be one of the principal causes of secondary hyperparathyroidism which is a very early complication of patients with CKD. Its diagnosis and treatment is crucial in the management of such patients.The treatment of the sHPT of CKD's patient includes dietary phosphate restriction, the use of phosphate binders, correction of hypocalcaemia, the use of vitamin D and its derivatives. The calcimimetic agent cinacalcet hydrochloride may be also used in combination with vitamin D. While the majority of patients can be controlled in this way, medical therapy is not always successful in achieving adequate control of secondary hyperparathyroidism. Oral medications (calcimimetics, recently developed phosphate binders, and active vitamin D derivatives amount to very high monthly costs, and have efficacy limitations as well as side-effects.

HIFU may become a valuable alternative treatment that help control secondary hyperparathyroidism in selected patients presenting with enlarged parathyroid gland(s) visible at ultrasonography,.

The aim of this study is to evaluate the efficacy and safety of HIFU treatment in chronic haemodialysis patients with secondary hyperparathyroidism presenting with enlarged parathyroid gland(s) which are visible at ultrasonography and for whom medical therapy has been unsuccessful.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The proportion of patients with a reduction from baseline of at least 30% in mean serum iPTH levels at 6 months after the last HIFU session and continuation of optimal medical therapy.

    Measured: 6 months after the last HIFU session

Secondary outcomes (1)
  1. Proportion of patients with a serum PTH in the KDIGO in the recommended range (approximately two to nine times the upper normal limit for the assay)

    Measured: at 6 months after last HIFU session

Questions about this trial

What is this clinical trial studying?

A study testing Ultrasonic ablation device in people with Secondary Hyperparathyroidism and End Stage Renal Disease, run by Theraclion at 3 sites in 2 countries.

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 4 inclusion and 13 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: withdrawn, as of the sponsor's last update on 6 May 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Italy, Spain. 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 was withdrawn before enrolling participants, so there are no results.

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?

The proportion of patients with a reduction from baseline of at least 30% in mean serum iPTH levels at 6 months after the last HIFU session and continuation of optimal medical therapy. (time frame: 6 months after the last HIFU session). 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 6 May 2014.
