About this study

Official title: An 8-week, Placebo-controlled, Double-blind, Randomized, Fixed-dose Efficacy and Safety Trial of Asenapine in Adolescent Subjects With Schizophrenia

This study is designed to evaluate whether asenapine, which is approved by the United States Food and Drug Administration (US FDA) for acute treatment of schizophrenia in adults, is also effective in adolescents with schizophrenia. Participants who qualify for the study will be randomly assigned to receive a fixed dose of asenapine (either 2.5 mg or 5 mg twice daily [BID]) or placebo for 8 weeks. Throughout the study, observations will be made on each participant at various times to assess the efficacy and safety of the study treatment. The primary objective of the trial is to demonstrate significant superiority of at least one asenapine dose to placebo, as measured by the change from baseline of the Positive and Negative Syndrome Scale (PANSS) total score at Day 56.

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 at Day 56

    The PANSS is a 30-item clinician-rated instrument for assessing the symptoms of schizophrenia. It consists of 3 subscales: positive subscale (7 items), negative subscale (7 items), and general psychopathology subscale (16 items). Positive symptoms refer to an excess or distortion of normal mental status (e.g., delusions). Negative symptoms represent a diminution or loss of normal functions (e.g., emotional withdrawal). For each item, symptom severity was rated on a 7-point scale, from 1=absent to 7=extreme. The PANSS total score for each participant was calculated as the sum of the rating assigned to each of the 30 PANSS items, and ranged from 30 to 210 with a higher score indicating greater severity of symptoms. The reported measure is the change from baseline at Day 56; improvement in symptoms is represented by negative values.

    Measured: Baseline and Day 56

Secondary outcomes (18)
  1. Change From Baseline in Clinical Global Impression of Severity (CGI-S) Score at Day 56

    Change from baseline in CGI-S score at Day 56 is the Key Secondary Outcome Measure. CGI-S is a 7-point scale for assessing the global severity of the participant's illness, with ratings from 1=normal, not ill to 7=very severely ill. The reported measure is the change from baseline at Day 56; improvement in symptoms is represented by negative values.

    Measured: Baseline and Day 56

  2. Change From Baseline in PANSS Positive Subscale Score at Day 56

    This measure reports results for the 7 items of the positive subscale of the PANSS, which is a 30-item clinician-rated instrument used to assess the symptoms of schizophrenia. Positive symptoms refer to an excess or distortion of normal mental status (e.g., delusions). For each item, symptom severity was rated on a 7-point scale, from 1=absent to 7=extreme. The PANSS positive subscale score for each participant was calculated as the sum of the rating assigned to each of the 7 subscale items, and ranged from 7 to 49 with a higher score indicating greater severity of symptoms. The reported measure is the change from baseline at Day 56; improvement in symptoms is represented by negative values.

    Measured: Baseline and Day 56

  3. Change From Baseline in PANSS Negative Subscale Score at Day 56

    This measure reports results for the 7 items of the negative subscale of the PANSS, which is a 30-item clinician-rated instrument used to assess the symptoms of schizophrenia. Negative symptoms represent a diminution or loss of normal functions (e.g., emotional withdrawal). For each item, symptom severity was rated on a 7-point scale, from 1=absent to 7=extreme. The PANSS negative subscale score for each participant was calculated as the sum of the rating assigned to each of the 7 subscale items, and ranged from 7 to 49 with a higher score indicating greater severity of symptoms. The reported measure is the change from baseline at Day 56; improvement in symptoms is represented by negative values.

    Measured: Baseline and Day 56

  4. Change From Baseline in PANSS Positive and Negative Subscale Scores Combined at Day 56

    This measure reports results for the combined positive subscale (7 items) and negative subscale (7 items) of the PANSS, which is a 30-item clinician-rated instrument used to assess the symptoms of schizophrenia. Positive symptoms refer to an excess or distortion of normal mental status (e.g., delusions). Negative symptoms represent a diminution or loss of normal functions (e.g., emotional withdrawal). For each of the total 14 items in the combined positive and negative subscales, symptom severity was rated on a 7-point scale, from 1=absent to 7=extreme. The PANSS positive and negative subscale scores combined for each participant was calculated as the sum of the rating assigned to each of the 14 combined subscale items, and ranged from 14 to 98 with a higher score indicating greater severity of symptoms. The reported measure is the change from baseline at Day 56; improvement in symptoms is represented by negative values.

    Measured: Baseline and Day 56

  14. CGI-I Responders

    A CGI-I responder was defined as a participant who had a CGI-I score of 1 (very much improved) or 2 (much improved) at the last available assessment of the study for that participant (i.e., endpoint). CGI-I is a 7-point scale for assessing the global improvement of the participant's illness relative to baseline, with ratings from 1=very much improved to 7=very much worse.

    Measured: Baseline up to Day 56

  15. Kaplan-Meier Estimate of Cumulative Percentage of Participants With CGI-I Response at End of Study

    CGI-I response was defined as the occurrence of a CGI-I score of 1 (very much improved) or 2 (much improved). CGI-I is a 7-point scale for assessing the global improvement of the participant's illness relative to baseline, with ratings from 1=very much improved to 7=very much worse. The Kaplan-Meier estimate reports the cumulative percentage of participants with CGI-I response from first drug intake up to approximately Day 58.

    Measured: Baseline up to approximately Day 58

  16. Change From Baseline in Children's Global Assessment Scale (CGAS) Score at Day 56

    CGAS is a 100-point scale measuring psychological, social, and school functioning in children aged 6-17. Minimum scores ranged from 1-10, representing the need for constant supervision (worse result) to maximum scores of 91-100, representing superior functioning (better result). The reported measure is the change from baseline at Day 56; improvement in functioning is represented by positive values.

    Measured: Baseline and Day 56

  17. Change From Baseline in Pediatric Quality of Life Enjoyment and Satisfaction Questionnaire (PQ-LES-Q) Total Score at Day 56

    PQ-LES-Q is a questionnaire to assess quality of life enjoyment and satisfaction in children and adolescents. The participant is asked to rate 15 items reflecting quality of life with respect to the previous week on a scale of 1=very poor to 5=very good. Items 1-14 assess specific areas (e.g., your health, your mood or feelings); Item 15 is a global assessment of overall quality of life. The PQ-LES-Q total score for each participant was calculated as the sum of the rating assigned to each of the first 14 items, and ranged from 14 to 70 with a higher score indicating better quality of life. The reported measure is the change from baseline at Day 56; improvement in quality of life is represented by positive values. This analysis used a last-observation-carried-forward (LOCF) approach; if no Day 56 value was available for a participant, the last available assessment prior to the Day 56 assessment was used.

    Measured: Baseline and Day 56

  18. Change From Baseline in PQ-LES-Q Overall Score (i.e., Item 15) at Day 56

    PQ-LES-Q is a questionnaire to assess quality of life enjoyment and satisfaction in children and adolescents. The participant is asked to rate 15 items reflecting quality of life with respect to the previous week on a scale of 1=very poor to 5=very good. Items 1-14 assess specific areas (e.g., your health, your mood or feelings); Item 15 is a global assessment of overall quality of life. The Item 15 result is defined to be the PQ-LES-Q overall score, and ranged from 1 to 5 with a higher score indicating better quality of life. The reported measure is the change from baseline at Day 56; improvement in quality of life is represented by positive values. This analysis used an LOCF approach; if no Day 56 value was available for a participant, the last available assessment prior to the Day 56 assessment was used.

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 7 inclusion and 6 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 21 May 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 6 Jun 2014). 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 at Day 56 (time frame: Baseline and Day 56). 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 NCT01190254, 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?
