What is being measured

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

  1. Modified Bond-Lader Visual Analog Scale Score After 50-mg Dose (Day 2)

    The Modified Bond-Lader Visual Analog Scale (VAS) uses a 100 mm line, each with a set of opposing adjectives at either end:Alert (=0) - Drowsy (=100); If patient is sleeping the Bond-Lader VAS will be assign a score of 100.

    Measured: At 1 hour post-dose, Day 2 (50 mg)

Secondary outcomes (12)
  1. Modified Bond-Lader Visual Analog Scale Score After 100-mg Dose (Day 3)

    The Modified Bond-Lader Visual Analog Scale (VAS) uses a 100 mm line, each with a set of opposing adjectives at either end:Alert (=0) - Drowsy (=100); If patient is sleeping the Bond-Lader VAS will be assign a score of 100.

    Measured: At 1 hour post-dose, Day 3 (100 mg)

  2. Modified Bond-Lader Visual Analog Scale Score After 200-mg Dose (Day 4)

    The Modified Bond-Lader Visual Analog Scale (VAS) uses a 100 mm line, each with a set of opposing adjectives at either end:Alert (=0) - Drowsy (=100); If patient is sleeping the Bond-Lader VAS will be assign a score of 100.

    Measured: At 1 hour post-dose, Day 4 (200 mg)

  3. Modified Bond-Lader Visual Analog Scale Score After 300-mg Dose (Day 5)

    The Modified Bond-Lader Visual Analog Scale (VAS) uses a 100 mm line, each with a set of opposing adjectives at either end:Alert (=0) - Drowsy (=100); If patient is sleeping the Bond-Lader VAS will be assign a score of 100.

    Measured: At 1 hour post-dose, Day 5 (300 mg)

  4. Modified Bond-Lader Visual Analog Scale Score After 300-mg Dose (Day 6)

    The Modified Bond-Lader Visual Analog Scale (VAS) uses a 100 mm line, each with a set of opposing adjectives at either end:Alert (=0) - Drowsy (=100); If patient is sleeping the Bond-Lader VAS will be assign a score of 100.

    Measured: At 1 hour post-dose, Day 6 (300 mg)

  5. Maximum Intensity Modified Bond-Lader Visual Analog Scale Score

    The Maximum Intensity Modified Bond-Lader VAS after dose (MaxIntVAS) is calculated as maximum possible value of VAS during that day at any from 1, 2, 3, 4, 5, 12, 13, 14 hours post-dose assessments

    Measured: During Day 2 (50 mg)

  6. Time to Maximum Intensity Modified Bond-Lader Visual Analog Scale Score

    Time (Tmax) to Maximum Intensity Modified Bond-Lader VAS after dose is corresponding assessment time (one from 1, 2, 3, 4, 5, 12, 13, 14 hours post-dose) of MaxIntVas

    Measured: During Day 2 (50 mg)

  7. Area Under the Modified Bond-Lader Visual Analog Scale-time Curve

    Area under the Modified Bond-Lader VAS-time curve is calculated by the linear trapezoidal formula which equals sum of (Ck+Ck+1)/2 multiplied by the time interval between k and k+1 observations, where Ck and Ck+1 are the corresponding the intensity of sedation evaluations measured by the Modified Bond-Lader VAS from 1 to 14 hours post-dose

    Measured: During Day 2 (50 mg)

  8. Change in Simpson-Angus Scale (SAS) Total Score

    SAS total score is the sum of the 10 individual-item scores (range:0-40), with the score for each item ranging from 0 to 4, higher scores indicate greater severity of Parkinsonian symptoms. Change : total score at day 7 minus total score at randomization. Increase in Change of total score indicates an increase in extrapyramidal motor symptoms.

    Measured: Randomization to Day 7

  9. Change in Barnes Akathisia Rating Scale (BARS) Global Score

    BARS global score is the 4th individual-item score on the BARS scale,the Global Assessment of Akathisia, with the score ranging from 0 to 5. Change : score at day 7 minus score at randomization. Increase in Change of BARS global score indicates an increase in akathisia.

    Measured: Randomization to Day 7

  10. Change in Abnormal Involuntary Movement Scale (AIMS) Total Score

    AIMS total score is the sum of the 10 individual-item scores (range:0-40), with the score for each item ranging from 0 to 4. Change : total score at day 7 minus total score at randomization. Increase in Change of total score indicates an increase in abnormal voluntary movements.

    Measured: Randomization to Day 7

  11. Number of Patients With Potential Extrapyramidal Symptoms (EPS)

    Number of patients with adverse events potentially associated with EPS collected by MedDRA Preferred Terms as akathisia, extrapyramidal disorder, restlessness

    Measured: From start of the study treatment to last dose plus 30 days

  12. Number of Patients With Potential Somnolence

    Number of patients with adverse events potentially associated with somnolence collected by MedDRA Preferred Terms as lethargy, sedation, somnolence

    Measured: From start of the study treatment to last dose plus 30 days

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Quetiapine Immediate Release and Quetiapine Extended Release in people with Bipolar Depression, run by AstraZeneca.

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 2 inclusion and 1 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 11 May 2011. 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 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?

Yes. Results are posted in the registry (first posted 31 Mar 2011). 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?

Modified Bond-Lader Visual Analog Scale Score After 50-mg Dose (Day 2) (time frame: At 1 hour post-dose, Day 2 (50 mg)). 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 NCT00926393, 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 11 May 2011.
