To Determine if Olanzapine is More Cost Effective Than Haloperidol for the Treatment of Schizophrenia
A Phase 4 study testing Haloperidol and Olanzapine in people with Schizoaffective Disorder and Schizophrenia, run by US Department of Veterans Affairs at 18 sites in United States.
Trial summary
Although currently marketed antipsychotic drugs are useful in the treatment of schizophrenia, efficacy and safety profiles need to be improved. Forty to eighty percent of patients either fail to respond or only partially respond to conventional antipsychotic agents. Read more about this study

About this study
Official title: CSP #451 - The Clinical and Economic Impact of Olanzapine in the Treatment of Schizophrenia
Although currently marketed antipsychotic drugs are useful in the treatment of schizophrenia, efficacy and safety profiles need to be improved. Forty to eighty percent of patients either fail to respond or only partially respond to conventional antipsychotic agents. Secondary symptoms may be unimproved even in patients who respond to treatment. A variety of adverse events occur in patients receiving currently available agents. The severity of these events contributes to the poor compliance that is observed in this patient population. Olanzapine is a novel antipsychotic agent with a reduced incidence of extrapyramidal symptoms. Other side effects are minimal.
Read the detailed description
Primary Hypothesis: To determine if olanzapine is more cost effective than haloperidol for the treatment of schizophrenia.
Secondary Hypothesis: Secondary objectives include evaluation of clinical efficacy, safety, social and vocational functioning, family burden, compliance and satisfaction for olanzapine relative to haloperidol.
Intervention: Olanzapine (5 mg to 20 mg/day), haloperidol (5 mg to 20 mg/day).
Primary Outcomes: Total inpatient hospital care costs are the primary outcome. Other major outcomes are total social costs (cost of VA health care, non-VA services and other specified social costs), efficacy measures (PANNS, BPRS, CGI Severity, and neurocognitive battery scores) and safety measures (adverse events, ECG?s).
Study Abstract: Although currently marketed antipsychotic drugs are useful in the treatment of schizophrenia, efficacy and safety profiles need to be improved. Forty to eighty percent of patients either fail to respond or only partially respond to conventional antipsychotic agents. Secondary symptoms may be unimproved even in patients who respond to treatment. A variety of adverse events occur in patients receiving currently available agents. The severity of these events contributes to the poor compliance that is observed in this patient population. Olanzapine is a novel antipsychotic agent with a reduced incidence of extrapyramidal symptoms. Other side effects are minimal.
Approximately 327 patients with schizophrenia or schizoaffective disorder were randomly assigned to one of two treatment groups. One treatment group was prescribed olanzapine with daily dosage ranging from 5 mg/day to 20 mg/day. The other treatment group was prescribed haloperidol with daily dosage also ranging from 5 mg/day to 20 mg/day. A semi-structured psychosocial case management treatment program is provided for all study patients. Patients were recruited from 18 VA medical centers over a 24-month period and were followed for one year. 18 patients were enrolled at one site that had its research program terminated during the study. Because of questions regarding the circumstances that led to the termination, these 18 patients will not be included in study analyses. The major objective of the study is to determine if olanzapine is more cost effective than haloperidol. Secondary objectives include evaluation of clinical efficacy, safety, social and vocational functioning, family burden, compliance and satisfaction for olanzapine relative to haloperidol.

A Phase 4 study testing Haloperidol and Olanzapine in people with Schizoaffective Disorder and Schizophrenia, run by US Department of Veterans Affairs at 18 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 1 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Where is the study taking place?
The record lists 18 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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00007774, 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 4 Feb 2009; AzTrials last refreshed its copy on 6 Nov 2026.
