Detailed Description:

This is a randomized, double-blind, placebo-controlled, Phase 2 safety/efficacy study in which two dose levels of EVP-6124 will be evaluated. Eligible for enrollment will be patients who meet clinical criteria for schizophrenia and who are taking chronic atypical anti-psychotic medication at a stable dose. This study will therefore evaluate the effects of EVP-6124 when administered concomitantly with anti-psychotic medication.

Patients will be randomized to one of the following groups: 0.3 mg or 1.0 mg EVP-6124, or placebo. Seventy-five patients per group. Study drug will be supplied as capsules and will be orally administered once daily for a total of 84 days.


Ages Eligible for Study:   18 Years to 55 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subjects who meet clinical criteria for schizophrenia or schizo-affective disorder utilizing the structured clinical interview (SCI)
  • Must be treated with a second generation anti-psychotic drug other than clozapine at a stable dose for at least 4 weeks and must have been on that drug and clinically stable for at least 8 weeks
  • Must have no more than "moderate" severity rating for negative symptoms: BPRS item ≤4
  • A minimal level of extrapyramidal symptoms (EPS); Simpson-Angus Scale total score ≤6
  • A minimal level of depression; Calgary Depression Scale total score ≤10
  • Must have a general health status acceptable for participation in a 12-week clinical trial
  • Fluency (oral and written) in the language in which the standardized tests will be administered
  • If a smoker, the ability to refrain from smoking for at least 30 minutes prior to any cognitive testing

Exclusion Criteria:
