PROTOCOL OUTLINE: This is a randomized, multicenter study. Patients are stratified by gender. Patients are randomized to receive surgery or follow up without surgery.

Patients receive parathyroidectomy (current standard care) or long term follow up without parathyroidectomy.

Quality of life is assessed before the study and then every 6 months. All patients are followed every 6 months until death.

Questions about this trial

What is this clinical trial studying?

A study testing parathyroidectomy and Observation in people with Hyperparathyroidism, run by National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).

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

Who may be eligible to take part?

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 30 May 2017. Status can change between updates, so confirm with the study contact before making plans.

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?

Quality of Life (time frame: 2 years). 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 NCT00004843, 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 30 May 2017.
