About this study

Official title: A Randomized, Double-Blind, Multiple Ascending Oral Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of PCO371 in Patients With Hypoparathyroidism

This is a multi-center, placebo-controlled, randomized, double-blind, multiple-ascending dose study in patients with hypoparathyroidism.

The total duration of study medication treatment will be 13 weeks and includes a Fixed-Dose Treatment period and a Dose Titration Treatment period. The Fixed-Dose Treatment period consists of multiple daily dosing at a fixed dose level. Once patients have completed the Fixed-Dose Treatment period, patients will enter the Dose Titration Treatment period where PCO371 (or placebo), oral calcium and oral active vitamin D can each be titrated according to the patient's albumin-corrected serum calcium level.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PCO371 in people with Hypoparathyroidism, run by Chugai Pharmaceutical at 11 sites in 3 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 18 inclusion and 30 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: stopped early, as of the sponsor's last update on 11 Jun 2021. 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 United States, Canada, Hungary. 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. Some participants in this study may receive a placebo. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study was stopped early (reason given: Terminated on the basis of the currently uncertain risk-benefit balance for the patients, and the strategic position of the development program). 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?

Treatment-emergent adverse events (time frame: 13 weeks). The study lists 7 primary outcomes in all. 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 11 Jun 2021.
