What is being measured

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

  1. AUC(0-t)

    Area under the plasma concentration versus time curve to the last measured concentration.

    h=hour

    Measured: 48 hours

  2. AUC (0-∞)

    The area under the plasma concentration curve was estimated by extrapolating to infinity AUC0-t. The extrapolation to infinity was done by regression with the last log-transformed data to estimate the terminal area by means of the line that maximized R'2 (coefficient of determination). The units are ng.h/mL.

    h=hours

    Measured: 48 hours

  3. Cmax

    Maximum plasma concentration

    Measured: 48 hours

Secondary outcomes (2)
  1. t1/2

    Apparent terminal elimination half-life

    Measured: 48 hours

  2. Tmax

    Time to maximum plasma concentration

    Measured: 48 hours

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Tramadol Contramid OAD and Zytram in people with Pain, run by Labopharm Inc..

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 10 inclusion and 14 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 27 Apr 2012. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 2 Jun 2009). 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?

AUC(0-t) (time frame: 48 hours). The study lists 3 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 NCT00911742, 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 27 Apr 2012.
