About this study

Official title: Efficacy of High Dose Olanzapine in a Controlled Fixed Dose-Response Trial for the Treatment of Schizophrenia and Schizoaffective Disorder

The purposes of this study are to assess the efficacy, safety, and side effects among doses approved by the Food and Drug Administration and higher (not FDA approved) doses of olanzapine in patients with schizophrenia or schizoaffective disorder.

Being tested
Olanzapine
Medical subject headings
Schizophrenia, Psychotic Disorders

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The primary objective of this study is to assess the fixed dose response relationship for efficacy between standard and higher doses of olanzapine (10, 20, and 40 mg/day) in patients with schizophrenia or schizoaffective disorder.

Secondary outcomes (19)
  1. To assess the dose response efficacy of olanzapine in improving psychopathology of schizophrenia as measured by a mean change from baseline on the PANSS subscores and Clinical Global Impression-Severity(CGI-S) Scale as well as by the absolute score

  2. of CGI-I (Improvement) Scale

  3. To assess the efficacy of olanzapine doses between treatment arms (e.g. 10 mg/day versus 40 mg/day ) in improving the psychopathology of schizophrenia as measured by mean changed from baseline on the PANSS total and subscores and Clinical Global

  4. Impression-Severity (CGI-S) Scale as well as by absolute score of CGI-I (Improvement) Scale

  5. To assess the efficacy of olanzapine doses as measured by efficacy scales in patients who have successfully completed the 2 week titration period

  6. To assess the efficacy of olanzapine doses within the standard range of 10 and 20 mg/day versus high dose 40 mg/day in improving the psychopathology of schizophrenia as measured by mean change from baseline on the PANSS total

  7. To assess the response rate of olanzapine doses in improving the psychopathology of schizophrenia. Clinical response is defined as an improvement (reduction) of =>20% from baseline in the PANSS total score

  8. To compare the time to response among all olanzapine treatment arms. Clinical response is defined as an improvement (reduction) of =>20% from baseline in the PANSS total score. In addition, the cumulative frequency distribution of differential

  9. rates of response reduction in PANSS total score will be assessed at 8 weeks

  10. To compare the dose response efficacy between all olanzapine treatment arms in improving depressive symptoms as measured by a mean change from baseline on the Montgomery-Asberg Depression Rating Scale (MADRS)

  11. To assess the efficacy between all olanzapine treatment arms in improving patients' overall level of functioning and health-related quality of life as measured by the Global assessment of Functioning (GAF) and the Heinrich Carpenter

  12. Quality of Life Scale (QLS)

  13. To analyze steady-state olanzapine plasma concentrations following 10, 20, and 40 mg daily dosing and examine the associations between state plasma levels, efficacy, and safety measures

  14. To assess the safety between treatment arms and the safety dose-response relationship between the olanzapine treatment groups as determined by:

  15. Treatment-emergent adverse events,

  16. ECG

  17. Vital signs and fasting laboratory analytes (clinical chemistry, hematology, lipid panel, and prolactin)

  18. Appetite as measured by the Eating Behavior Assessment

  19. Extrapyramidal symptoms as measured by the Modified Simpson-Angus Scale, The Barnes Akathisia Rating Scale, and the Abnormal Involuntary Movement Scale (AIMS)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Olanzapine in people with Schizophrenia and Schizoaffective Disorder, run by Eli Lilly and Company at 33 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Jan 2007. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 33 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The primary objective of this study is to assess the fixed dose response relationship for efficacy between standard and higher doses of olanzapine (10, 20, and 40 mg/day) in patients with schizophrenia or schizoaffective disorder.. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00100776, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jan 2007.
