About this study

Official title: Melatonin Replacement Therapy Effects on Cardiac Autonomic Activity in Pinealectomized Patients

This is an open-label, single-arm, single-center, proof-of-concept study to assess the effects of melatonin on cardiac autonomic activity in melatonin non-proficient pinealectomized patients.

Read the detailed description

This is an open-label, single-arm, single-center, proof-of-concept study to assess the effects of melatonin on cardiac autonomic activity in melatonin non-proficient pinealectomized patients. The study consists of a screening period, followed by a 3-month melatonin treatment period, and a 6-month washout follow-up period. Adverse events were monitored with respect to seriousness, intensity, relationship to treatment, action taken and outcome of the event.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Melatonin Replacement TherapyDrug

    Melatonin (Aché Pharmaceutics, Brazil), 3 mg, administered in the evening, 30 minutes before the usual bedtime, every day for 3 months. After discontinuation of melatonin therapy, patients are followed up for 6 months to assess safety parameters and cardiac autonomic activity.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. cardiac autonomic function - heart rate variability

    The cardiac autonomic function was determined through heart rate variability (HRV) measures after polysomnography ECG recordings.

    Measured: 9 months

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Melatonin Replacement Therapy in people with Pineal Tumor, run by University of Sao Paulo at 1 site in Brazil.

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 2 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 21 Mar 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 Brazil. 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.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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 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?

cardiac autonomic function - heart rate variability (time frame: 9 months). 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 NCT03885258, which also lists 7 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 21 Mar 2019.
