About this study

Official title: A Phase 1, Double-Blind, Placebo-Controlled, Single and Multiple Ascending Dose Study of REM0045392 to Evaluate Pharmacokinetics, Pharmacodynamics, Safety, Tolerability, and Food Effect in Healthy Male Participants and in a Panel of Healthy Elderly Participants (Both Sexes)

This study is testing if the medicine REM0045392 is safe and well-tolerated. It also looks at whether food affects how the medicine works.

The medicine will be tested in Healthy men (Part 1 and 2) and Healthy Older men and women (Part 3).

Participants will take the medicine once (in Part 1) or during 14 days (in Part 2 and 3), with increasing doses.

REM0045392 is being developed as a treatment for Alzheimer's disease.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing REM0045392 in people with Healthy, run by reMYND at 1 site in Belgium.

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 14 inclusion and 34 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 4 Feb 2026. 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 Belgium. 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 was stopped early (reason given: Sponsor decision). 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?

Number of Participants with Treatment Related Adverse Events (time frame: Throughout the study, until 7-10 days post last dose). 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 4 Feb 2026.
