What is being measured

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

  1. Measurement of Schizophrenia Symptoms: Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score

    The Positive and Negative Syndrome Scale is a 30-item rating scale specifically developed to asses both the positive and negative symptom syndromes of patients with schizophrenia. The PANSS total score is rated based on a structured clinical interview with the patient and supporting clinical information obtained from family, hospital staff, or other reliable informants. This assessment provides scores in 9 clinical domains, including a positive syndrome, a negative syndrome, depression, a composite index, and general psychopathology. Each item is scored on a 7-point (1 to 7) scale, with 1 being minimal impact, and 7 being highest impact. The cumulative score ranges from 30 to 210. A negative change score indicates improvement.

    Measured: Baseline to Week 6

Secondary outcomes (1)
  1. Measurement of Schizophrenia Symptoms: Change From Baseline in Clinical Global Impression-Severity (CGI-S)

    The Clinical Global Impressions-Severity scale is a clinician-rated scale that measures the overall severity of a participant's illness in comparison with the severity of illness in other participants the physician has observed. The participant is rated on a scale from 1 to 7 with 1 indicating a "normal state" and 7 indicating "among the most extremely ill participants." A higher score indicates greater illness. A negative change score indicates improvement.

    Measured: Baseline to Week 6

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Cariprazine in people with Schizophrenia, run by Forest Laboratories at 41 sites in 4 countries.

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 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 14 Nov 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 41 sites in India, United States, Colombia, South Africa. 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. 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 14 Nov 2018). 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?

Measurement of Schizophrenia Symptoms: Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score (time frame: Baseline to Week 6). 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 NCT01104779, which also lists 6 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 14 Nov 2018.
