What is being measured

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

  1. Change from Baseline in Fluorodeoxyglucose Positron Emission Tomography (FDG-PET) Metabolic Measure of Standard Uptake Value Ratio (SUVR) for Whole Brain, Hippocampal and Dorsolateral Prefrontal Cortices

    The effects of AGN-242071 on brain metabolic activity or glucose metabolism will be determined using the FDG-PET scan by reporting results as SUVR.

    Measured: Baseline (Day -3 to Day -1) to Day 28

  2. Percentage of Participants with Treatment-Emergent Adverse Events (TEAE)

    An adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. An AE that occurs during the treatment period will be considered a TEAE if it was not present before the first dose or if it was present but increased in severity during the treatment period.

    Measured: Day 1 to Day 35

  3. Percentage of Participants with Changes from Baseline in Clinically Significant Clinical Laboratory Values

    Clinical laboratory safety tests include Chemistry, Hematology and Urinalysis.

    Measured: Baseline (Day -3 to Day -1) to Day 35

  4. Percentage of Participants with Changes from Baseline in Clinically Significant Vital Signs

    Vital signs include systolic and diastolic blood pressure, pulse rate, weight, respiration rate, and temperature.

    Measured: Baseline (Day -3 to Day -1) to Day 35

  5. Percentage of Participants with Changes from Baseline in Clinically Significant Electrocardiogram (ECG) Findings

    A standard 12-lead ECG will be performed.

    Measured: Baseline (Day -3 to Day -1) to Day 35

  6. Percentage of Participants who have Suicidal Ideation or Behaviours as determined by Columbia-Suicide Severity Rating Scale (C-SSRS)

    The C-SSRS is a clinician-rated instrument that reports the severity of both suicidal ideation and suicidal behavior since the last visit.

    Measured: Baseline (Day 1) to Day 35

  7. Clearance of AGN-242071

    Clearance will be determined utilizing a population pharmacokinetic (PK) approach implemented in non-linear mixed effects modeling (NONMEM®) software.

    Measured: Day 1 to Day 28

  8. Volume of Distribution of AGN-242071

    Volume of Distribution will be determined utilizing a population PK approach implemented in NONMEM® software.

    Measured: Day 1 to Day 28

  9. Cmax: Maximum Plasma concentration for AGN-242071

    Measured: Day 28

  10. AUC: Area Under the Curve for AGN-242071

    Measured: Day 28

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AGN-242071, Donepezil and Memantine in people with Alzheimer's Disease, run by Allergan at 6 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 2 inclusion and 25 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: withdrawn, as of the sponsor's last update on 2 Nov 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 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 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 withdrawn before enrolling participants, so there are no results.

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 Fluorodeoxyglucose Positron Emission Tomography (FDG-PET) Metabolic Measure of Standard Uptake Value Ratio (SUVR) for Whole Brain, Hippocampal and Dorsolateral Prefrontal Cortices (time frame: Baseline (Day -3 to Day -1) to Day 28). The study lists 10 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 Nov 2018.
