Brief Summary

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.

Outcome Measures

Primary Outcomes (9)

  • 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).

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

  • 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.

    Days 1 and 21

  • 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.

    Days 1 and 21

  • 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.

    Days 1 and 21

  • 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.

    Days 1 and 21

  • 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.

    Days 1 and 21

  • 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.

    Days 1 and 21

  • 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.

    Days 1 and 21

  • 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.

    Days 1 and 21
