Secondary outcomes (6)
  1. Number of Participants With Treatment-emergent Adverse Events (TEAEs) Based on Severity

    Measured: From the first dose up to 1 month following last dose with investigational medicinal product (IMP) in each part of the study

  2. Number of Participants With Clinically Significant Changes in Electrocardiogram (ECG) Values

    Measured: Up to end of treatment in each part of the study (up to an average of 15 days)

  3. Number of Participants With Clinically Significant Changes in Vital Sign Measurements

    Measured: Up to end of treatment in each part of the study (up to an average of 15 days)

  4. Number of Participants With Clinically Significant Changes in Laboratory Assessments

    Measured: Up to end of treatment in each part of the study (up to an average of 15 days)

  5. Number of Participants With Clinically Significant Changes in Physical and Neurological Examination Results

    Measured: Up to end of treatment in each part of the study (up to an average of 15 days)

  6. Changes in Suicidality Assessed Using the Columbia Suicide Severity Rating Scale (C-SSRS) Score

    The C-SSRS includes 'yes' or 'no' responses for assessment of suicidal ideation and behavior as well as numeric ratings for the severity of ideation, if present (from 1 to 5, with 5 being the most severe). Greater lethality or potential lethality of suicidal behaviors (endorsed on the behavior subscale) indicates increased risk.

    Measured: Up to end of treatment in each part of the study (up to an average of 15 days)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Emraclidine, Itraconazole and Carbamazepine in people with Healthy Volunteers, run by Cerevel Therapeutics, 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 9 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: finished, as of the sponsor's last update on 2 Apr 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?

Part A: Maximum Observed Plasma Concentration (Cmax) of Emraclidine and its Metabolite CV-0000364 (time frame: Pre-dose and at multiple time points post-dose from Day 1 in TP 1 up to Day 15 in TP 2 of Part A). The study lists 9 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 2 Apr 2024.
