  4. Plasma melatonin half life

    Time required for the concentration of plasma melatonin to decrease to half of its starting dose

    Measured: Up to 720 minutes after taking the tablet

  5. Evolution of the plasma concentration of 6-sulfatoxymelatonin

    The change in plasma 6-sulfatoxymelatonin concentration

    Measured: Up to 720 minutes after taking the tablet

  6. Plasma 6-sulfatoxymelatonin AUC

    Area Under the Curve of plasma 6-sulfatoxymelatonin

    Measured: Up to 720 minutes after taking the tablet

  7. Plasma 6-sulfatoxymelatonin Cmax

    Peak concentration of plasma 6-sulfatoxymelatonin

    Measured: Up to 720 minutes after taking the tablet

  8. Plasma 6-sulfatoxymelatonin Tmax

    Time take to reach Cmax of plasma 6-sulfatoxymelatonin

    Measured: Up to 720 minutes after taking the tablet

  9. Plasma 6-sulfatoxymelatonin half life

    Time required for the concentration of plasma 6-sulfatoxymelatonin to decrease to half of its starting dose

    Measured: Up to 720 minutes after taking the tablet

  10. Evolution of the plasma zinc concentration

    The change in plasma zinc concentration

    Measured: Up to 720 minutes after taking the tablet

  11. Plasma zinc AUC

    Area Under the Curve of plasma zinc

    Measured: Up to 720 minutes after taking the tablet

  12. Plasma zinc Cmax

    Peak concentration of plasma zinc

    Measured: Up to 720 minutes after taking the tablet

  13. Plasma zinc Tmax

    Time take to reach Cmax of plasma zinc

    Measured: Up to 720 minutes after taking the tablet

  14. Plasma zinc half life

    Time required for the concentration of plasma zinc to decrease to half of its starting dose

    Measured: Up to 720 minutes after taking the tablet

  15. Evolution of state of drowsiness

    The change in (Visual Analog Scale)VAS score, minimum = 0 and maximum = 10 higher score means a worse outcome

    Measured: Up to 720 minutes after taking the tablet

Questions about this trial

What is this clinical trial studying?

A study testing dietary supplement, 1 tablet containing delayed release melatonin, zinc and lemon balm in people with Melatonin Bioavailability, run by Larena SAS at 1 site in France.

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 6 inclusion and 22 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 13 Nov 2023. 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 France. 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?

Evolution of the plasma melatonin concentration (time frame: Up to 720 minutes after taking the tablet). 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 NCT05419466, 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 13 Nov 2023.
