What is being measured

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

  1. Sum of Pain Intensity Differences (SPID 24)

    Pain Intensity assessed at predefined time points (at 0.25, 0.5, 1, 2, 4, 6, 8, 12, 16, 20 and 24 hours after first drug administration) over a 24 hour period using an 11-point Numeric Rating Scale (NRS) where a score of zero indicates "no pain" and a score of ten indicates "pain as bad as you can imagine". Pain Intensity Differences at each predefined time point (calculated as post-baseline NRS values - baseline NRS values) were analyzed. Negative SPID24 values indicate a decrease in pain intensity and positive values indicate an increase in pain intensity since baseline.

    Measured: Baseline value; up to 24 hours after first study drug administration

Secondary outcomes (23)
  1. Mean Pain Intensity Scores at Fixed Time Points

    The mean pain intensity at fixed time points in the trial for all participants is listed. The pain intensity was measured using the Pain Intensity (PI). Pain intensity was assessed on 11-point numerical rating scale from 0 = no pain to 10 = pain as bad as you can imagine.

    Measured: Baseline; up to 48 hours

  2. Pain Intensity Differences at Fixed Time Points

    Pain Intensity (PI) was assessed on 11-point numerical rating scale from 0 = no pain to 10 = pain as bad as you can imagine. Pain Intensity Difference (PID) was the difference between baseline pain intensity (prior to the first dose) and the pain intensity at the time. A negative number indicates a decrease in pain in the whole treatment group. The greater the negative pain intensity difference value the greater the pain relief in the treatment arm. A score of 0 indicates that there has been no change in pain in a treatment group. A positive value indicates an increase in pain in the treatment group.

    Measured: Starting at 15 minutes and up to 48 hours after first drug administration

  3. Patient Global Impression of Change After 12 Hours of Treatment

    In the Patient Global Impression of Change (PGIC) the participant indicates the perceived change over the treatment period. The participant verbally rated their impression of overall status with 1 of 7 possible responses (very much improved, much improved, minimally improved, no change, minimally worse, much worse, very much worse).

    Measured: Baseline value to 12 hours after first study drug administration

  4. Patients Global Impression of Change After 24 Hours of Treatment

    In the Patient Global Impression of Change (PGIC) the participant indicates the perceived change over the treatment period. The participant verbally rated their impression of overall status with 1 of 7 possible responses (very much improved, much improved, minimally improved, no change, minimally worse, much worse, very much worse).

    Measured: Baseline value to 24 hours after study drug administration

  5. Patient Global Impression of Change After 48 Hours of Treatment

    In the Patient Global Impression of Change (PGIC) the participant indicates the perceived change over the treatment period. The participant verbally rated their impression of overall status with 1 of 7 possible responses (very much improved, much improved, minimally improved, no change, minimally worse, much worse, very much worse).

    Measured: Baseline value to 48 hours after first study drug administration

  6. Sum of Pain Intensity Differences After 60 Minutes

    Pain Intensity (PI) was assessed on 11-point numerical rating scale from 0 = no pain to 10 = pain as bad as you can imagine. Pain Intensity Difference (PID) was the difference between the PI after fixed times after first dose and the baseline PI (prior to the first dose). The Sum of Pain Intensity Differences over 60 minutes was calculated. If the value is negative then the baseline pain intensity was greater than the pain intensity measured after dosing.

    Measured: Baseline value to 60 minutes after first study drug administration

  7. Sum of Pain Intensity Differences After 4 Hours

    Pain Intensity (PI) was assessed on 11-point numerical rating scale from 0 = no pain to 10 = pain as bad as you can imagine. Pain Intensity Difference (PID) was the difference between the PI after fixed times after first dose and the baseline PI (prior to the first dose). The Sum of Pain Intensity Differences over 4 hours was calculated. If the values are negative (then the baseline pain intensity was greater than the pain intensity measured after dosing).

    Measured: Baseline value to 4 hours after first study drug intake

  8. Sum of Pain Intensity Differences After 8 Hours

    Pain Intensity (PI) was assessed on 11-point numerical rating scale from 0 = no pain to 10 = pain as bad as you can imagine. Pain Intensity Difference (PID) was the difference between the PI after fixed times after first dose and the baseline PI (prior to the first dose). The Sum of Pain Intensity Differences over 8 hours was calculated. If the values are negative (then the baseline pain intensity was greater than the pain intensity measured after dosing).

    Measured: Baseline value to 8 hours after first study drug administration

  9. Sum of Pain Intensity Differences After 12 Hours

    Pain Intensity (PI) was assessed on 11-point numerical rating scale from 0 = no pain to 10 = pain as bad as you can imagine. Pain Intensity Difference (PID) was the difference between the PI after fixed times after first dose and the baseline PI (prior to the first dose). The Sum of Pain Intensity Differences over 12 hours was calculated. If the values are negative (then the baseline pain intensity was greater than the pain intensity measured after dosing).

    Measured: Baseline value to 12 hours after first study drug administration

  10. Sum of Pain Intensity Differences After 48 Hours

    Pain Intensity (PI) was assessed on 11-point numerical rating scale from 0 = no pain to 10 = pain as bad as you can imagine. Pain Intensity Difference (PID) was the difference between the PI after fixed times after first dose and the baseline PI (prior to the first dose). The Sum of Pain Intensity Differences over 60 minutes was calculated. If the values are negative (then the baseline pain intensity was greater than the pain intensity measured after dosing).

    Measured: Baseline value to 48 hours after first study drug administration

  11. Number of Participants With 30% Response After 12 Hours, Based on Pain Intensity Scores

    Individual participant response. Number of participants that reported a 30% or more reduction in pain intensity from the administration of the first dose to 12 hours after the first study drug administration are counted as having a response if their pain intensity decreased by 30% from their baseline value.

    Measured: Baseline value to 12 hours after first study drug administration

  12. Number of Participants With 30% Response After 24 Hours, Based on Pain Intensity Scores

    Individual participant response. Number of participants that reported a 30% or more reduction in pain intensity from the administration of the first dose to 24 hours after the first study drug administration are counted as having a response if their pain intensity decreased by 30% from their baseline value.

    Measured: Baseline value to 24 hours after first study drug administration

  13. Number of Participants With 30% Response After 48 Hours, Based on Pain Intensity Scores

    Individual participants response.

  17. Time to First Rescue Medication

    The median time to first rescue medication intake (600 mg ibuprofen) in hours.

    Measured: up to 48 hours

  18. Time to Perceptible Pain Relief

    When the participant began to feel any pain-relieving effect after the administration of the first dose they were requested to stop the first stopwatch. The time was noted. This measured when the participant first felt any difference in the pain.

    Measured: up to 48 hours

  19. Time to Meaningful Pain Relief

    The participant was instructed to stop the stopwatch when they had meaningful pain relief. That is, when the pain relief made a real difference, after the first drug administration.

    Measured: up to 48 hours

  20. Pharmacokinetic Concentrations of Tapentadol

    Tapentadol concentrations were measured in participants in the tapentadol treatment arm. Serum was analyzed by means of liquid chromatography coupled to tandem mass spectrometry with a lower limit of quantification (LLOQ) at 0.2 ng/mL.

    Measured: 15 minutes to 20 hours after first drug administration

  21. Pharmacokinetic Concentrations of Tapentadol-O-glucuronide

    Tapentadol-O-glucuronide is the metabolite of tapentadol. Metabolites are sometimes referred to as "breakdown products". The body alters the administered medication to a metabolite so that can be more easily or quickly removed from the body. Tapentadol-O-glucuronide concentrations were measured in participants in the tapentadol treatment arm. Serum was analyzed by means of liquid chromatography coupled to tandem mass spectrometry with a lower limit of quantification (LLOQ) at 0.2 ng/mL.

    Measured: 15 minutes to 20 hours after first drug administration

  22. Mean Pain Intensity Scores at Relative Time- Tapentadol Randomized Participants

    The pain intensity at the relative time points are the pain intensity before and one hour after study drug administration. The pain intensity was measured using the Pain Intensity (PI). Pain intensity was assessed on 11-point numerical rating scale from 0 = no pain to 10 = pain as bad as you can imagine.

    Measured: Baseline; for the first 6 administrations

  23. Mean Pain Intensity Scores at Relative Time - Matching Placebo Randomized Participants

    The pain intensity at the relative time points are the pain intensity before and one hour after study drug administration. The pain intensity was measured using the Pain Intensity (PI). Pain intensity was assessed on 11-point numerical rating scale from 0 = no pain to 10 = pain as bad as you can imagine.

    Measured: Baseline; for the first 6 administrations

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Tapentadol in people with Bunion and Pain, run by Grünenthal GmbH at 1 site in United States.

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 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 28 Oct 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 24 Jun 2013). 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?

Sum of Pain Intensity Differences (SPID 24) (time frame: Baseline value; up to 24 hours after first study drug administration). 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 28 Oct 2019.
