Phase 1
Terminated
Conditions
Schizophrenia
Interventions
Drug: Placebo
Registration Number
NCT01568203
Lead Sponsor

Brief Summary

The purpose of this study is to assess the safety and tolerability of AMG 579 following a single oral dose administration in healthy subjects (Part A) and in patients with schizophrenia or stable schizoaffective disorder (Part B).

  • Clinically stable, as judged by the investigator, and in a non-acute phase for at least 12 weeks within enrollment. If patient is on antipsychotic medications, they must be on second generation oral antipsychotic therapy (eg, ziprasidone, quetiapine, olanzapine, etc) for at least 8 weeks within enrollment and at least one month within enrollment on a stable dose
Exclusion Criteria
  • Hospitalized for psychiatric symptoms in the 3 months within enrollment
  • Patients with evidence of mental retardation by history or clinical examination or known premorbid IQ ≤ 70
  • Current risk of self-harm or violence as determined by the investigator, or current risk of suicide or history of suicidal behavior within 12 months of enrollment, and/or ongoing suicidal ideation as assessed using Columbia-Suicidal Severity Rating Scale (C-SSRS) at screening (eg, any response of "yes" to the Suicidal Ideation questions on the C-SSRS in the past 12 months).
