What is being measured

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

  1. Change from baseline in physical examination

    Physical examination

    Measured: Subjects will be followed up to 14 days post-dose

  2. Rates of adverse events and serious adverse events

    Adverse events and serious adverse events

    Measured: Subjects will be followed up to 14 days post-dose

  3. Rates of early termination due to adverse events

    Early termination due to adverse events

    Measured: Subjects will be followed up to 14 days post-dose

  4. Change from baseline in vital signs, clinical laboratory values, and electrocardiogram results

    Vital signs, clinical laboratory values, and electrocardiogram results

    Measured: Subjects will be followed up to 14 days post-dose

  5. Change from baseline dissociative effects, psychosis, and hallucinatory symptoms as measured by the Neuropsychiatric Inventory (NPI-12)

    Neuropsychiatric Inventory (NPI-12) - NPI-12 assesses 12 behavioral domains common in dementia. Higher scores indicate more severe illness.

    Measured: Subjects will be followed up to 14 days post-dose

  6. Change from baseline in suicidal ideation and behavior as measured by the Sheehan Suicidality Tracking Scale (S-STS)

    Sheehan Suicidality Tracking Scale (S-STS) is a 16-item scale that assesses the seriousness of suicidality phenomena on a likert-type scale (0 to 4) ranging from 0 = not at all to 4 = extremely

    Measured: Subjects will be followed up to 14 days post-dose

  7. Change from baseline in motor complications as measured by the Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part 4

    Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part 4 includes 6 items assessing motor complications, higher scores indicate more serious illness.

    Measured: Subjects will be followed up to 14 days post-dose

  8. Change in total score of the Sheehan Suicidality Tracking Scale (S-STS)

    Sheehan Suicidality Tracking Scale (S-STS) is a 16-item scale that assesses the seriousness of suicidality phenomena on a likert-type scale (0 to 4) ranging from 0 = not at all to 4 = extremely

    Measured: Subjects will be followed up to 14 days post-dose

Secondary outcomes (6)
  1. Change from baseline in the One Back test

    The One Back test is a measure of working memory

    Measured: Week 12

  2. Change from baseline in the Two Back test

    The Two Back test is a measure of working memory

    Measured: Week 12

  3. Change from baseline in the Groton Maze Learning Test

    The Groton Maze Learning test is a measure of problem solving and reasoning

    Measured: Week 12

  4. Change from baseline in the Identification Test

    The Identification test is a measure of visual attention

    Measured: Week 12

  5. Change from baseline in the International Shopping List Test

    The International Shopping List test is a measure of verbal learning

    Measured: Week 12

  6. Change from baseline on Continuous Paired Associate Learning Test

    The Continuous Paired Associate Learning test is a measure of visual associate memory

    Measured: Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing NYX-458 in people with Mild Cognitive Impairment and Mild Dementia, run by Aptinyx at 26 sites 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 7 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: under way, not looking for participants, as of the sponsor's last update on 27 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 26 sites 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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 from baseline in physical examination (time frame: Subjects will be followed up to 14 days post-dose). The study lists 8 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 27 Oct 2022.
