About this study

Official title: Copeptin After an Oral Stimulation With Macimorelin in Healthy Volunteers - The Macicop-Study

This study investigates stimulation of the posterior pituitary gland by oral Macimorelin (a ghrelin receptor Agonist) to be a novel diagnostic test in the polyuria-polydipsia syndrome.

Read the detailed description

Copeptin measurements upon intravenous arginine stimulation discriminate patients with diabetes insipidus versus patients with primary polydipsia with a high diagnostic accuracy. An oral test would be easier to perform, causes less risks and discomfort for the patients and would require less resources in clinical practice. This study investigates stimulation of the posterior pituitary gland by oral Macimorelin (a ghrelin receptor Agonist) to be a novel diagnostic test in the polyuria-polydipsia syndrome.

  6. Change in Prolactin value (yg/L)

    evaluate Prolactin values after the intake of of a single oral-dose Macimorelin

    Measured: baseline blood exam (timepoint 0) and further blood collections after 30, 45, 60, 90 and 120 minutes after baseline blood collection

  7. Change in Cortisol value (ng/mL)

    evaluate Cortisol values after the intake of of a single oral-dose Macimorelin

    Measured: baseline blood exam (timepoint 0) and further blood collections after 30, 45, 60, 90 and 120 minutes after baseline blood collection

  8. Change in Adrenocorticotropin (ACTH) value ( pg/mL)

    evaluate ACTH values after the intake of of a single oral-dose Macimorelin

    Measured: baseline blood exam (timepoint 0) and further blood collections after 30, 45, 60, 90 and 120 minutes after baseline blood collection

  9. Change in Luteotropin (LH) value (U/L)

    evaluate LH values after the intake of of a single oral-dose Macimorelin

    Measured: baseline blood exam (timepoint 0) and further blood collections after 30, 45, 60, 90 and 120 minutes after baseline blood collection

  10. Change in Follicle-stimulating hormone value(FSH) (IU/mL)

    evaluate FSH values after the intake of of a single oral-dose Macimorelin

    Measured: baseline blood exam (timepoint 0) and further blood collections after 30, 45, 60, 90 and 120 minutes after baseline blood collection

What is this clinical trial studying?

A study testing Macimorelin 0.5mg/kg body weight and Macimorelin 0.75mg/kg body weight in people with Polyuria-polydipsia Syndrome, run by University Hospital, Basel, Switzerland at 1 site in Switzerland.

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 1 inclusion and 9 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 8 Aug 2019. 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 Switzerland. 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 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?

Change in Copeptin value (pmol/l), after intake of Macimorelin of 0.5mg/kg body weight (time frame: baseline blood exam (timepoint 0) and further blood collections after 30, 45, 60, 90 and 120 minutes after baseline blood collection). 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 NCT03844217, 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 8 Aug 2019.
