What is being measured

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

  1. Pain intensity difference from baseline to final assessment using the VAS scale (100 mm, 0 being "no pain" and 100 being "worst pain imaginable").

    Arthritis Pain Intensity measured by a 100mm Visial Analog Scase (VAS)

    Measured: 4 weeks

Secondary outcomes (1)
  1. WOMAC Osteoarthritis Index, SF36

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Extended-Release Hydrocodone/Acetaminophen in people with Pain, run by Abbott.

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 8 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 19 Jan 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Pain intensity difference from baseline to final assessment using the VAS scale (100 mm, 0 being "no pain" and 100 being "worst pain imaginable"). (time frame: 4 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 19 Jan 2011.
