About this study

Official title: A Three-Period Study to Evaluate the Effects of Modafinil on the Single-Dose Pharmacokinetics of MK-6552 in Healthy Male Participants

The goal of this study is to learn what happens to MK-6552 in a person's body over time. Researchers will compare what happens to levels of MK-6552 in people's blood when it is taken with and without modafinil. Researchers also want to learn about the safety of MK-6552 taken with and without modafinil and if people tolerate it.

Conditions
Healthy, Narcolepsy
Being tested

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MK-6552 and Modafinil in people with Healthy and Narcolepsy, run by Merck Sharp & Dohme LLC 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 3 inclusion and 3 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 30 Oct 2024. 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 United States. 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?

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 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?

Number of Participants Who Experience an Adverse Event (AE) (time frame: Up to approximately 1 month). The study lists 11 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 30 Oct 2024.
