What is being measured
The primary outcome is the main question the study is designed to answer.
Time-weighted Sum of Pain Relief Rating and Pain Intensity Difference From 0-8 Hours (SPRID 0-8)
SPRID: time-weighted sum of pain relief rating combined with pain intensity difference (PRID) over 8 hours. SPRID 0-8 score range: -8 (worst) to 56 (best). PRID: sum of Pain intensity differences (PID) and pain relief rating (PRR) at each time point. PRID score range: -1=worst to 7=best. PID: baseline pain severity score minus pain severity score at a given time point (pain severity score range 0=none to 3=severe; baseline score range 2=moderate to 3=severe). PID score range: -1(worst) to 3 (best). PRR: assessed on 5-point pain relief rating scale (0=No relief to 4=Complete relief).
Measured: 0 to 8 hours
Time to Onset of Meaningful Relief
Participants evaluated the time to meaningful relief by stopping a second stopwatch labeled 'meaningful relief' at the moment they first began to experience meaningful relief. Stopwatch was active up to 8 hours after dosing or until stopped by the participant, or rescue medication was administered.
Measured: 0 to 8 hours
Secondary outcomes (13)
Time to Confirmed First Perceptible Relief
Participants evaluated the time to first perceptible relief by stopping a stopwatch labeled 'first perceptible relief' at the moment they first began to experience any relief. Stopwatch was active up to 8 hours after dosing or until stopped by the participant, or rescue medication was administered. The first perceptible relief was considered confirmed if the participant also stopped the second stopwatch indicating meaningful relief.
Measured: 0 to 8 hours
Pain Relief Rating (PRR)
PRR was evaluated at different time points during the study up to 8 hours after taking the study medication, and immediately before rescue medication was taken (if necessary). PRR was assessed on a 5-point categorical pain relief rating scale where 0=No relief to 4=Complete relief.
Measured: 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8 hours
Pain Intensity Difference (PID)
PID was derived by subtracting the pain severity score at a given post-dosing time point (pain severity score range 0 [none] to 3 [severe]) from the baseline score (Baseline pain severity score range 2 [moderate] to 3 [severe]). Total possible score range for PID: -1 (worst) to 3 (best).
Measured: 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8 hours
Sum of Pain Relief Rating and Pain Intensity Difference (PRID)
PRID was sum of PID and PRR at each post-dosing time point. The overall possible score range, for PRID was -1 (worst) to 7 (best). PID was derived by subtracting the pain severity score at a given post-dosing time point (pain severity score range 0 [none] to 3 [severe]) from the baseline score (Baseline pain severity score range 2 [moderate] to 3 [severe]). Total possible score range for PID: -1 (worst) to 3 (best). PRR was assessed on 5-point categorical pain relief rating scale (0=No relief to 4=Complete relief).
Measured: 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8 hours
Time-weighted Sum of Pain Intensity Difference (SPID)
SPID: time-weighted sum of PID over 2, 3, 6 and 8 hours. SPID scores range was -2 (worst) to 6 (best) for SPID 0-2, -3 (worst) to 9 (best) for SPID 0-3, -6 (worst) to 18 (best) for SPID 0-6, -8 (worst) to 24 (best) for SPID 0-8. PID: baseline pain severity score minus pain severity score at a given time point (pain severity score range 0=none to 3=severe; baseline score range 2=moderate to 3=severe). Total score range for PID: -1(worst) to 3 (best).
Measured: 0-2, 0-3, 0-6, 0-8 hours
Time-weighted Sum of Pain Relief Rating (TOTPAR)
TOTPAR: time-weighted sum of PRR scores over 2, 3, 6 and 8 hours. TOTPAR score range was 0 (worst) to 8 (best) for TOTPAR 0-2, 0 (worst) to 12 (best) for TOTPAR 0-3, 0 (worst) to 24 (best) for TOTPAR 0-6, 0 (worst) to 32 (best) for TOTPAR 0-8. PRR was evaluated at different time points during the study up to 8 hours, and immediately after taking rescue medication (if necessary). PRR was assessed on a 5-point categorical pain relief rating scale wherein 0=No relief to 4=Complete relief.
Measured: 0-2, 0-3, 0-6, 0-8 hours
Time-weighted Sum of Pain Relief Rating and Pain Intensity Difference (SPRID)
SPRID: time-weighted sum of PRID over 2, 3, 6 and 8 hours. SPRID score range:-2 (worst) to 14(best) for SPRID 0-2, -3(worst) to 21(best) for SPRID 0-3, -6(worst) to 42(best) for SPRID 0-6, -8(worst) to 56(best) for SPRID 0-8. PRID:sum of PID and PRR at each time point. Total score range for PRID: -1=worst to 7=best. PID:baseline pain severity score minus pain severity score at given time(score range 0=none to 3=severe; baseline score range 2=moderate to 3=severe). Total score range for PID: -1(worst) to 3(best), PRR: scored on 5-point pain relief rating scale(0=No relief to 4=Complete relief).
Measured: 0-2, 0-3, 0-6, 0-8 hours
Cumulative Percentage of Participants With Meaningful Relief
Percentage of participants with meaningful relief evaluated by stopping the stopwatch labeled 'meaningful relief' at the moment the participant first began to experience meaningful relief. Stopwatch was active up to 8 hours after dosing or until stopped by the participant, or rescue medication was administered.
Measured: 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8 hours
Cumulative Percentage of Participants With Confirmed First Perceptible Relief
Percentage of participants with first perceptible relief was evaluated by stopping a stopwatch labeled 'first perceptible relief' at the moment the participant first began to experience any relief. Stopwatch was active up to 8 hours after dosing or until stopped by the participant, or rescue medication was administered. The first perceptible relief was considered confirmed if the participant also stopped the second stopwatch indicating meaningful relief.
Measured: 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8 hours

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Novel Ibuprofen and Standard Ibuprofen in people with Pain, run by Pfizer.
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 5 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 17 Aug 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. 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 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 17 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?
Time-weighted Sum of Pain Relief Rating and Pain Intensity Difference From 0-8 Hours (SPRID 0-8) (time frame: 0 to 8 hours). The study lists 2 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 NCT01098747, which also lists 2 linked publications.
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 17 Aug 2012.
