What is being measured

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

  1. Adverse Events

    Total number of adverse events

    Measured: 3 days

  2. Serum Potassium - Average Concentration From Trapezoidal Area Under the Curve (AUC)

    The mean AUC value was calculated as AUC (calculated using the trapezoidal method) divided by the length of the sampling period.

    Measured: up to 740 min after start dosing for each treatment day

  3. Blood Glucose - Average Concentration From Trapezoidal Area Under the Curve (AUC)

    The mean AUC value was calculated as AUC (calculated using the trapezoidal method) divided by the length of the sampling period.

    Measured: up to 140 min after start dosing for each treatment day

  4. Electrocardiogram (ECG)- Average Trapezoidal Area Under the Curve (AUC)

    The mean AUC of QTcF (ECG interval measured from the beginning of the Q wave to the end of the T wave, corrected for heart rate using Fridericia's formula)was calculated as AUC (calculated using the trapezoidal method) divided by the length of the sampling period.

    Measured: up to 740 min after start dosing for each treatment day

  5. Vital Sign (Blood Pressure)- Average Trapezoidal Area Under the Curve (AUC)

    The mean AUC value was calculated as AUC (calculated using the trapezoidal method) divided by the length of the sampling period.

    Measured: up to 740 min after start dosing for each treatment day

  6. Vital Sign (Pulse Rate)- Average Trapezoidal Area Under the Curve (AUC)

    The mean AUC value was calculated as AUC (calculated using the trapezoidal method) divided by the length of the sampling period.

    Measured: up to 740 min after start dosing for each treatment day

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Symbicort Turbuhaler and Terbutaline Turbuhaler in people with Asthma, run by AstraZeneca at 2 sites in Japan.

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 3 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 29 Aug 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Japan. 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. 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 29 Aug 2012). 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?

Adverse Events (time frame: 3 days). The study lists 6 primary outcomes in all. 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 NCT00837967, 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 29 Aug 2012.
