Collaborator:

William Carpenter, University of Maryland
ClinicalTrials.gov Identifier:
NCT01012167
First received: April 28, 2009
Last updated: May 2, 2017

  Purpose

The project is designed to address the following two primary aims:

  1. To determine whether adjunctive oxytocin is superior to placebo for the treatment of persistent negative symptoms, as measured by the SANS total score, in people with schizophrenia.
  2. To determine whether adjunctive Galantamine is superior to placebo for the treatment of cognitive impairments, as measured by improvement on a composite neurocognitive score in people with schizophrenia.

The investigators will also address the following secondary aims:

  1. To determine whether people with schizophrenia treated with adjunctive oxytocin, compared to placebo, will show greater improvement on markers of negative symptom liability including: social affiliation, facial affect recognition, olfactory discrimination, initiation of smooth pursuit and latency of internally-driven saccades.
  2. To determine whether people with schizophrenia treated with adjunctive Galantamine, compared to placebo, will show greater improvement on markers of cognitive impairment liability including: predictive pursuit, P50 sensory gating and visual-spatial working memory.

The investigators will address the following exploratory aims:

  1. To determine whether changes in markers of negative symptom liability are correlated with changes in SANS total score.
  2. To determine whether changes in markers of cognitive impairment liability are correlated with changes in the composite neurocognitive score.
  3. To determine the response to oxytocin of all cognition domains assessed by the MATRICS battery, and to determine the response to Galantamine of all cognition domains assessed by the MATRICS, which are not included in the primary neurocognitive outcome score.
  4. To determine whether there is a differential response of oxytocin and Galantamine on the SANS total score, composite neurocognitive score, and with the phenotypic measures of negative symptom and cognitive impairment liability.
  5. To determine whether oxytocin and Galantamine are associated with:

    • adverse effects on positive or depressive symptoms;
    • adverse effects on motor symptoms;
    • adverse effects on laboratory and EKG measures;
    • increased occurrence of side effects;
    • social interest that is independent of sexual desire.

Primary Outcome Measures:
  • Scale for the Assessment of Negative Symptoms (SANS) Total Score [ Time Frame: Every other week for 6 weeks ]
    Mean SANS Total Score by Treatment and Week. SANS total score range = 0-85. Higher scores indicate more severe negative symptoms.

  • Mean Z-Scores for Composite Cognitive Primary Outcome* by Treatment Group and Week [ Time Frame: Treatment Week 0 and Week 6 ]
    * Composite Cognitive Primary Outcome = mean of z-scores from the Brief Assessment of Cognition in Schizophrenia (BACS) Symbol Digit test, the Hopkins Verbal Learning Test (HVLT), and the Rapid Visual Information Processing test (RVIP). Z-scores for each test were calculated as Z = (individual patient score - pooled baseline mean)/(pooled baseline standard deviation). Higher values of the composite score represent a better outcome.


Secondary Outcome Measures:

  • Brief Psychiatric Rating Scale (BPRS) - Psychosis Score [ Time Frame: Every other week for 6 weeks ]
    The psychosis score is calculated by adding the scores for scales #4 Conceptual Disorganization, #11 Suspiciousness, #12 Hallucinatory Behavior, and #15 Unusual Thought Content. Each scale ranges from "1=Not Present" to "7=Very Severe". The minimum psychosis score is 4 and the maximum psychosis score is 28. A higher score indicates a more severe psychosis rating.

  • Calgary Depression Scale (CDS) - Total Score [ Time Frame: Every other week for 6 weeks ]
    Total score calculated by adding scores for scales #1-#9. Each scale ranges from "0=Absent" to "3=Severe". The minimum total CDS score is 0 and the maximum total CDS score is 27. A higher score indicates a more severe depression rating.

The minimum total ASEX score is 5 and the maximum score is 30. Lower scores indicate more positive sexual experiences.

  • Arizona Sexual Experience Questionnaire (ASEX) Male [ Time Frame: Once during evaluation and once at the end of 6 weeks of study treatment ]
    Mean ASEX total scores by treatment and week for male participants. Total scores are calculated by adding scores for scales #1-#5. Total scores are calculated by adding scores for scales #1-#5. Each scale ranges from "1=Easily/Extremely" to "6=Never/None". The minimum total ASEX score is 5 and the maximum score is 30. Lower scores indicate more positive sexual experiences.

Total scores calculated by adding scores from scales #1-#11. Each scale ranges from "0=None/Normal" to "4=Extreme/Severe". The minimum total score is 0 and the maximum score is 44. Higher scores indicate a more severe extrapyramidal side effect rating.

  • Abnormal Involuntary Movement Scale (AIMS) [ Time Frame: Treatment Week 0 and Week 6 ]

Criteria

Inclusion Criteria:

  • Any race
  • Subjects will meet DSM-IV criteria for schizophrenia or schizoaffective disorder
  • Judged clinically stable and will not exceed threshold levels of positive, depressive, and/or extrapyramidal symptoms
  • The minimum level of negative symptoms will be defined as follows:

    • Scale for the Assessment of Negative Symptoms (SANS) total score (minus the global items, and inappropriate affect, poverty of content of speech and attentional items) 20 or greater; OR
    • SANS alogia global item score 3 or greater
  • The maximum level of psychotic, depressive, and extrapyramidal symptoms at the beginning and end of leading in:

    • Brief Psychiatric Rating Scale (BPRS) psychotic factor score (4-items) less or equal to 16
    • BPRS Anxiety/Depression factor score (4-items) less than or equal to 14
    • Simpson-Angus-Scale (SAS) total score (13-items) less than or equal to 10
  • Subjects will be required to be on the same antipsychotic(s) for two months and on the same dose for the last month

Exclusion Criteria:

  • Participants with an organic brain disorder; mental retardation; or a medical condition, whose pathology or treatment could alter the presentation or treatment of schizophrenia or significantly increase the risk associated with the proposed treatment protocol
  • Participants with intermittent alcohol or substance use will not be excluded unless they have met DSM-IV criteria for alcohol or substance abuse (other than nicotine) within the last month.
  • Participants may be treated with one or more antipsychotics, except chlorpromazine, thioridazine, or mesoridazine. These latter antipsychotics are excluded because of the concern that their anticholinergic properties may interfere with the accurate assessment of galantamine efficacy.
  • Participants may not be treated with anticholinergic medications or have clinically significant extrapyramidal symptoms. Additionally, subjects treated with glycopyrrolate will be accepted.
  • Female participants may not be pregnant
  • Female subjects may not be taking olanzapine at doses higher than 30 mg . Male subjects may not be taking olanzapine at doses higher than 40 mg.
