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). The study in healthy subjects (Part A) concluded, and following a protocol amendment, enrolled only patients with schizophrenia or stable schizoaffective disorder (Part B).

Condition Intervention Phase
Schizophrenia Drug: AMG 579 Drug: Placebo Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Basic Science
Official Title: Phase I, Randomized, Placebo-Controlled, Ascending Single Dose Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of AMG 579 in Healthy Adult Subjects and Patients With Stable Schizophrenia or Schizoaffective Disorder

Further study details as provided by Amgen:

Primary Outcome Measures:
  • Number of adverse events per subject to include clinically significant changes in neurological examinations, safety laboratory tests, electrocardiograms, and vital signs [ Time Frame: Up to 15 days ]
  • Incidence of treatment-emergent suicidal ideation and behavior [ Time Frame: Up to 15 days ]
    Measured by Columbia-Suicide Severity Rating Scale (C-SSRS)

Secondary Outcome Measures:
  • Peak plasma and cerebrospinal fluid (CSF; cohort 4 healthy subjects only) concentration (Cmax) of AMG 579 [ Time Frame: Up to 15 days ]
  • Time of peak plasma and CSF (cohort 4 only healthy subjects only) concentration (tmax) of AMG 579 [ Time Frame: Up to 15 days ]
  • Area under the plasma and CSF (cohort 4 healthy subjects only) concentration versus time curve (AUC) of AMG 579 [ Time Frame: Up to 15 days ]
  • Terminal phase half-life (t1/2) in plasma and CSF (cohort 4 healthy subjects only) of AMG 579 [ Time Frame: Up to 15 days ]
  • Scores on Simpson Angus Scale (SAS) and Barnes Akathesia Rating Scale (BARS) [ Time Frame: Up to 15 days ]

Enrollment: 50
Study Start Date: September 2011
Study Completion Date: June 2012
Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: AMG 579 Drug: AMG 579
3 dose levels of single oral dose administration of AMG 579 in healthy subjects (Part A), and 5 dose levels of single oral dose administration of AMG 579 in patients with schizophrenia or schizoaffective disorder (Part B)
Placebo Comparator: Placebo Drug: Placebo
Matching placebo control for AMG 579 at each dose level


Ages Eligible for Study:   18 Years to 60 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Diagnosis of schizophrenia (chronic, all types) or schizoaffective disorder according to Diagnostic and Statistical Manual of Mental Disorders, 4th edition Text Revision (DSM-IV-TR) criteria and by Mini International Neuropsychiatric Interview (M.I.N.I.) 6.0 for Schizophrenia and Psychotic Disorders Studies
  • Body weight greater or equal to 50 kg and body mass index (BMI) between 18 and 38.0 kg/m2, inclusive, at screening
  • Patient is judged by the Investigator to be likely to tolerate being off of antipsychotic medications for the duration of the trial (for patients withdrawing from or currently not taking antipsychotic medications)
  • 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).

Additional critera apply. Eligibility criteria for healthy subjects (Part A) not outlined above.
