What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in Negative Symptoms of Schizophrenia Measured by the Negative Symptom Assessment (NSA) Scale Total Score
The NSA Scale is a 16-item clinician-rated instrument for rating the negative symptomatology of schizophrenia. Total score ranges from 16 (best) to 96 (worst), with greater scores indicating greater severity of symptoms.
Measured: Baseline of A7501013 to Day 365
Secondary outcomes (1)
Change From Baseline in Quality of Life Measured by the Quality of Life Scale (QLS) Total Score
The QLS is a 21-item clinician-rated scale for rating psychosocial functioning (Interpersonal Relations, Instrumental Role, Intrapsychic Foundations, and Common Objects and Activities). The score ranges from 0 (worst) to 126 (best), with greater values indicating better quality of life.
Measured: Baseline of A7501013 to Day 365

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing asenapine and olanzapine in people with Schizophrenia, run by Organon and Co.
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 5 inclusion and 4 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 9 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.
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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 5 Jul 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Change From Baseline in Negative Symptoms of Schizophrenia Measured by the Negative Symptom Assessment (NSA) Scale Total Score (time frame: Baseline of A7501013 to Day 365). 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 NCT00174265, which also lists 1 linked publication.
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 9 Feb 2022.
