What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CelecoxibDrug

    Initial dose: Celecoxib 200mg tablet x 2 will be administrated during a period from 1 to 2 hours post lateral mandibular impacted third molar tooth extraction in subjects with "moderate pain" or "severe pain"rated as 45.0 mm or more on the VAS

  • CelecoxibDrug

    Additional dose: Celecoxib 200mg tablet x 1 will be administrated during a period from 5 to 12 hours post-initial dose of Celecoxib 400mg in subjects who require an additional analgesic dose for any pain

  • PlaceboDrug

    Additional dose: Placebo (tablet) will be administrated during a period from 5 to 12 hours post-initial dose of Celecoxib 400mg in subjects who require an additional analgesic dose for any pain

What is being measured

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

  1. Efficacy Rate (Percentage) of Patient's Impression

    Patient's impression was assessed by self-report and was entered in the patient diary, based on the following categories: "Excellent", " Good", "Fair" and "Poor".

    Efficacy rate was calculated from the following formula, "The number of participants assessed as Excellent or Good" over "total participants" multiplied by 100.

    Measured: 2 hours post-additional dose

Secondary outcomes (3)
  1. Number of Participants in Each Pain Intensity (PI) With 4 Categories

    Pain intensity was entered in the patient diary on the following categories: "No pain", "Mild pain", "Moderate pain" and "Severe pain".

    Measured: 2 hours after additional dose

  2. Pain Intensity Measured by Visual Analog Scale (VAS)

    The Pain intensity was recorded on the 100 mm VAS in the patient diary, where 0 mm=no pain, 100 mm=unbearable maximal pain.

    Measured: 2 hours post-additional dose

  3. Differences in Pain Intensity (PI) Measured by VAS Among Participants

    The differences in PI were obtained by subtracting the PI at each time point from the Baseline PI score.

    Measured: Pre-additional dose (baseline) and 2 hours post-additional dose

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Celecoxib in people with Pain, run by Pfizer's Upjohn has merged with Mylan to form Viatris Inc. at 22 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 8 inclusion and 2 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 2 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 22 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. 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?

Yes. Results are posted in the registry (first posted 19 Nov 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?

Efficacy Rate (Percentage) of Patient's Impression (time frame: 2 hours post-additional dose). 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 NCT01062113, 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 2 Feb 2021; AzTrials last refreshed its copy on 1 Nov 2026.
