About this study
Official title: HEXT: The Hypoparathyroidism Studies, EXTended: The Effect of PTH on the Skeleton in Hypoparathyroidism
This is an open-label study of PTH(1-84) treatment that seeks:
- To determine the actions of PTH(1-84) to provide long term control of serum calcium and urinary calcium excretion with use of standard amounts of calcium and vitamin D supplementation.
- To determine the extent to which PTH(1-84) improves quality-of-life on long-term basis.
- To establish the safety of PTH(1-84) when administered for up to 12 years.
- To attempt to quantify improvements in the typical signs/symptoms of hypoparathyroidism post PTH administration.
There will be one visit conducted every six months in the study offices of the principal investigator, Dr. John Bilezikian. In addition to these visits, there will be, for new patients who have not used PTH (1-84) before, a Screening Visit four weeks prior to the baseline visit for the purpose of performing screening labs as well as a Pre-Baseline Local Quest Lab performed to ensure stability prior to Baseline.
Read the detailed description
Hypoparathyroidism is a rare disorder in which parathyroid hormone (PTH) is markedly decreased or absent from the circulation. It is the only remaining hormone deficiency state for which replacement with the missing hormone has been heretofore unavailable. The hypoparathyroid state is due either to autoimmune destruction of the parathyroid glands or to loss of parathyroid function after neck surgery. Without PTH, calcium homeostasis is markedly abnormal, the most salient clinical feature of which is a reduced serum calcium concentration. The hypocalcemia is associated with other important abnormalities such as markedly reduced parameters of bone turnover. PTH(1-84) is the ideal therapeutic approach to hypoparathyroidism. The current mainstay of therapy, calcium and vitamin D, has important clinical limitations. Large doses of calcium and vitamin D are required and often associated with hypercalciuria and vitamin D toxicity. Moreover, this approach does not correct the skeletal deficiencies resident in the bones themselves due to lack of PTH. In contrast, PTH(1-84) replaces precisely what is missing in this disorder. The research question is: What are the long-term safety and efficacy parameters of PTH(1-84) therapy in hypoparathyroidism?
Preliminary data suggest that treatment with PTH(1-84) for up to 4 years improves control of the serum and urine calcium concentration safely. Since hypoparathyroidism is a chronic disorder, it is important to know whether these salutary effects continue to be seen beyond 4 years. There is a need to determine the safety and efficacy treatment of PTH(1-84) in hypoparathyroidism beyond 4 years.

A Phase 3 study testing open-label PTH(1-84) in people with Hypoparathyroidism, run by Columbia University at 1 site in United States.
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 12 inclusion and 24 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 5 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 5 Jul 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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 Dose of Calcium Supplementation (time frame: Baseline, up to 4 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 NCT01199614, which also lists 14 linked publications.
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 5 Jul 2024.
