About this study

Official title: A Double-Blind, Placebo-Controlled Randomized Study to Assess the Safety, Tolerability, and Pharmacokinetics of EVP-6124 in Participants With Schizophrenia on Stable Monotherapy With Selected Antipsychotics

This study in patients with schizophrenia is designed to provide preliminary evidence of the safety, tolerability, and pharmacokinetics as well as the effects on cognitive function of 2 doses of EVP-6124 compared with placebo when given with the patient's usual antipsychotic medication.

Read the detailed description

Study drug will be supplied as capsules and will be orally administered once daily for a total of 21 days. Eligible subjects will be admitted to an inpatient study unit on Day -6 (six days before the first dose of study drug is administered) and will remain confined to the inpatient study unit throughout the dosing phase. Safety assessments, PK sampling, and cognitive testing will be performed.

What is being measured

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

  1. Number of Participants With Serious and Non-serious Adverse Events Spontaneously Reported by Subject and/or Observed by Investigator.

    Safety and tolerability was measured by number of reported adverse events (serious and non-serious) and repeated clinical evaluation of physical examinations, vital signs, 12-lead electrocardiogram (ECG), 24-hour continuous cardiac monitoring, and laboratory tests (hematology/blood chemistry/urinalysis).

    Measured: Screening (Day -5 for continuous cardiac monitoring) to Day 22

  2. EVP-6124 Maximum Plasma Concentration (Cmax), Patients on Aripiprazole

    Blood samples for pharmacokinetic (PK) analyses were taken before dosing with EVP-6124 on Days 1 and 21.

    Measured: Days 1 and 21

  3. EVP-6124 Time to Maximum Concentration (Tmax), Patients on Aripiprazole

    Blood samples for PK analyses were taken before dosing with EVP-6124 on Days 1 and 21.

    Measured: Days 1 and 21

  4. EVP-6124 Area Under the Curve (AUC[0-24 h]), Patients on Aripiprazole

    Blood samples for PK analyses were taken before dosing with EVP-6124 on Days 1 and 21.

    Measured: Days 1 and 21

  5. EVP-6124 Half-life (T[1/2]), Patients on Aripiprazole

    Blood samples for PK analyses were taken before dosing with EVP-6124 on Days 1 and 21.

    Measured: Days 1 and 21

  6. EVP-6124 Maximum Plasma Concentration (Cmax), Patients on Paliperidone/Risperidone

    Blood samples for PK analyses were taken before dosing with EVP-6124 on Days 1 and 21.

    Measured: Days 1 and 21

  7. EVP-6124 Time to Maximum Concentration (Tmax), Patients on Paliperidone/Risperidone

    Blood samples for PK analyses were taken before dosing with EVP-6124 on Days 1 and 21.

    Measured: Days 1 and 21

  8. EVP-6124 Area Under the Curve (AUC[0-24 h]), Patients on Paliperidone/Risperidone

    Blood samples for PK analyses were taken before dosing with EVP-6124 on Days 1 and 21.

    Measured: Days 1 and 21

  9. EVP-6124 Half-life (T[1/2]), Patients on Paliperidone/Risperidone

    Blood samples for PK analyses were taken before dosing with EVP-6124 on Days 1 and 21.

    Measured: Days 1 and 21

Secondary outcomes (4)
  1. N100 Gating Ratio

    N100 auditory evoked potential response (amplitude measured in microvolts) using the sensory gating paradigm. Measured by electroencephalography (EEG) as the amplitude ratio of test stimulus to conditioning stimulus. Plotted on a unitless scale of 0 to 2. Normalization is suggested by a lower value.

    Measured: Days -1 to 20

  2. P50 Amplitude Difference

    P50 auditory evoked potential response (amplitude measured in microvolts) using sensory gating paradigm. Measured by EEG as amplitude difference (conditioning stimulus minus test stimulus). Plotted on a scale of -0.2 to 0.8 microvolts. Normalization is suggested by a higher value.

    Measured: Days -1 to 20

  3. MMN Summed Amplitude

    Mismatch negativity (MMN) auditory evoked potential response (amplitude in microvolts) using orienting paradigm. Measured by EEG and calculated as the voltage difference over 100-200 msec following stimulus onset (rare stimulus minus frequent stimulus). Plotted on a scale of -1.2 to 0.2 microvolts. Normalization is suggested by a more negative value.

    Measured: Days -1 to 20

  4. P300 Peak Amplitude

    P300 auditory evoked potential response (amplitude in microvolts) using orienting paradigm. Measured by EEG and calculated as the peak amplitude over 250-500 msec following stimulus onset (rare stimulus minus frequent stimulus). Plotted on a scale of -0.4 to 1.2 microvolts. Normalization is suggested by a more positive value.

    Measured: Days -1 to 20

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing EVP-6124 (0.3 mg/day), EVP-6124 (1.0 mg/day) and Antipsychotic therapy in people with Schizophrenia and Schizoaffective Disorder, run by FORUM Pharmaceuticals Inc 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 10 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 21 Jun 2012. 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. 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?

Yes. Results are posted in the registry (first posted 21 Jun 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 Serious and Non-serious Adverse Events Spontaneously Reported by Subject and/or Observed by Investigator. (time frame: Screening (Day -5 for continuous cardiac monitoring) to Day 22). 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?

On the ClinicalTrials.gov record for NCT01556763, which also lists 1 linked publication.

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 21 Jun 2012.
