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

Placebo
PLACEBO COMPARATORMatching placebo was administered as one capsule per day for 21 days.
EVP-6124 (1.0 mg/day)
EXPERIMENTALEVP-6124 was administered as one 1.0 mg capsule per day for 21 days.
EVP-6124 (0.3 mg/day)
EXPERIMENTALEVP-6124 was administered as one 0.3 mg capsule per day for 21 days.
Interventions
EVP-6124 was administered as one 0.3 mg capsule per day for 21 days.
EVP-6124 was administered as one 1.0 mg capsule per day for 21 days.
Concomitant therapy with antipsychotic medication (aripiprazole \[10 to 30 mg/day\], olanzapine \[10 to 20 mg/day\], paliperidone \[3 to 12 mg/day\], or risperidone \[2 to 16 mg/day\]), taken at the same time each day as the EVP-6124 dose. Patients must have been taking concomitant therapy for at least 2 weeks at a stable dose to be eligible for the study.

- Negative urine drug screen at screening and inpatient observation baseline period (Day -6), except for a short-acting benzodiazepine if prescribed for insomnia.
- Fluent in English (speaking, writing, and reading).
You may not qualify if:
- Female subject who was pregnant or breast-feeding.
- Any active clinically significant medical condition within 1 month (30 days) prior to screening.
- A history of substance (drug) dependence or substance or alcohol abuse within the 12 months before randomization as defined in the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV).
- A score of \>5 on any item on the PANSS (Positive and Negative Syndrome Scale) Positive subscale at baseline during the inpatient observation period (Day -1).
- Any laboratory test abnormalities at screening indicating hepatic or renal dysfunction, or any other laboratory test abnormalities deemed by the investigator to be clinically significant.
- Any hematologic malignancy or solid tumor diagnosed within 3 years prior to study entry with the exception of localized skin cancer or carcinoma in situ of the cervix.
- Known to have had or was a carrier of HBsAg, HCV antibody, or had a positive result to the HIV-1 and/or HIV-2 antibodies.
- Uncooperative with or could not complete the study procedures.
- Received an investigational drug within 30 days before screening.
