What is being measured

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

  1. Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score.

    PANSS total score measures symptoms of schizophrenia and consists of responses to 30 items: 7 items from the positive subscale (P1-P7), 7 items from the negative subscale (N1-N7) and 16 items from the general psychopathology subscale (G1-G16). Responses to each item range from 1 = absence of symptom, to 7 = most extreme symptoms. The PANSS total score is the sum of the scores for all 30 items, and ranges from 30 to 210, with a higher score indicating greater severity of symptoms. Change from baseline values that are negative represent an improvement in symptoms.

    Measured: Baseline and Day 42

An improvement in symptoms is represented by change from baseline values that are negative.

    Measured: Baseline and Day 42

  3. Change From Baseline in PANSS General Psychopathology Score.

    PANSS General Psychopathology subscale measures symptoms of schizophrenia and consists of responses to 16 items (G1-G16). Responses to each item range from 1 = absence of symptom, to 7 = most extreme symptoms. The PANSS General Psychopathology subscale is the sum of the scores for all 16 items and ranges from 16 to 112, with a higher score indicating greater severity of symptoms.. An improvement in symptoms is represented by change from baseline values that are negative.

    Measured: Baseline and Day 42

    PANSS Marder Factor Positive symptom score measures symptoms of schizophrenia and consists of responses to 8 items (P1,P3,P5,P6,N7,G1,G9,G12). Responses to each item range from 1 = absence of symptom, to 7 = most extreme symptoms. The PANSS Marder Factor Positive symptom score is the sum of the scores for all 8 items and ranges from 8 to 56, with a higher score indicating greater severity of symptoms. An improvement in symptoms is represented by change from baseline values that are negative.

    Measured: Baseline and Day 42

  9. Percentage of Participants Who Were PANSS Responders.

    PANSS total score measures symptoms of schizophrenia and consists of responses to 30 items: 7 items from the positive subscale (P1-P7), 7 items from the negative subscale (N1-N7) and 16 items from the general psychopathology subscale (G1-G16). Responses to each item range from 1 = absence of symptom, to 7 = most extreme symptoms. The PANSS total score is the sum of the scores for all 30 items, and ranges from 30 to 210, with a higher score indicating greater severity of symptoms. The PANSS total score was determined at baseline and then at Day 42, and a participant with a 30% or greater reduction from baseline in PANSS total score at Day 42 was considered a PANSS responder.

    Measured: Day 42

  10. Change From Baseline in Clinical Global Impressions -Severity of Illness (CGI-S) Score.

    The CGI-S is a score that measures the severity of overall bipolar illness. The score ranges on a scale from 1 to 7, where 1 is normal, and 7 is very severely ill. Change from baseline values that are negative represent an improvement in symptoms.

    Measured: Baseline and Day 42

  11. Percentage of Participants Who Were Clinical Global Impressions - Improvement (CGI-I) Responders.

    The CGI-I is a score on a 7-point scale for assessing the change from preceding phase of overall symptoms of bipolar disorder during the treatment of an acute episode or in longer term illness prophylaxis. Compared to the baseline, the CGI-I score ranges from 1 = very much improved since initiating treatment, to 7 = very much worse since initiating treatment. The CGI-I score was assessed at baseline and Day 42. Compared to the baseline measurement, a CGI-I responder had a score at Day 42 of 3 (minimally improved), 2 (much improved) or 1 (very much improved).

    Measured: Day 42

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Asenapine 5 mg and Asenapine 10 mg 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 11 inclusion and 10 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 20 Jun 2024. 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. Some participants in this study may receive a placebo. 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 17 Apr 2015). 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 Positive and Negative Syndrome Scale (PANSS) Total Score. (time frame: Baseline and Day 42). 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 NCT01098110, 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 20 Jun 2024.
