What is being measured
The primary outcome is the main question the study is designed to answer.
Time Weighted Sum of Pain Relief Rating (PRR) and Pain Intensity Difference (PID) Scores From 0 to 8 Hours Post-dose (SPRID 0-8): Ibuprofen + Caffeine Versus Ibuprofen
SPRID 0-8: time-weighted sum of PRID scores from 0 to 8 hours. PRID: sum of PID and PRR at each post-dose time point. PRR score: at each post-dose time point participants answered to question "How much relief do you have from your starting pain?" on a 5-point scale: 0= none, 1= a little, 2= some, 3= a lot, 4= complete; higher scores = more relief from pain. Numerical pain severity rating (NPSR) scale: at baseline and each post-dose time point participants answered to question "How much pain do you have at this time?" on an 11-point scale: range from 0= no pain to 10= worst possible pain; higher scores = worse pain. PID score: NPSR score at baseline (0 hour) minus NPSR score at each post-dose time point; overall possible PID score range at a post-dose time point: -10 to 10, higher positive value = greater improvement. Overall possible SPRID 0-8 score range: -80 to 112, higher scores = more improvement in pain.
Measured: From 0 to 8 hours post-dose on Day 1

SPID 0-2, SPID 0-4, SPID 0-6, SPID 0-8: time-weighted sum of PID scores from 0 to 2, 0 to 4, 0 to 6 and 0 to 8 hours post-dose respectively. NPSR scale: at baseline and each post-dose time point participants answered to question "How much pain do you have at this time?" on an 11-point scale: score range from 0 = no pain to 10 = worst possible pain; higher scores = worse pain. PID score: NPSR score at baseline (0 hour) minus NPSR score at each post-dose time point; overall possible PID score range at a post-dose time point: -10 to 10, higher positive value = greater improvement. Overall possible range: SPID 0-2 = -20 to 20; SPID 0-4 = -40 to 40; SPID 0-6 = -60 to 60; SPID 0-8 = -80 to 80. Higher SPID scores = more improvement in pain.
Measured: From 0 to 2, 0 to 4, 0 to 6 and 0 to 8 hours post-dose on Day 1
Time Weighted Sum of Pain Relief Rating Scores From 0 to 2 (TOTPAR 0-2), 0 to 4 (TOTPAR 0-4), 0 to 6 (TOTPAR 0-6) and 0 to 8 Hours Post-dose (TOTPAR 0-8)

Overall possible range: TOTPAR 0-2 = 0 to 8; TOTPAR 0-4 = 0 to 16; TOTPAR 0-6 = 0 to 24; TOTPAR 0-8 = 0 to 32. Higher TOTPAR scores = more improvement in pain.
Measured: From 0 to 2, 0 to 4, 0 to 6 and 0 to 8 hours post-dose on Day 1
Sum of Pain Relief Rating and Pain Intensity Difference (PRID) Scores at 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, and 8 Hours Post-dose
PRID: sum of PID and PRR at each post-dose time point. PRR score: at each post-dose time point participants answered to a question "How much relief do you have from your starting pain?" on a 5-point scale: 0= none, 1= a little, 2= some, 3= a lot, 4= complete; higher scores = more relief from pain. NPSR scale: at baseline and each post-dose time point participants answered to a question "How much pain do you have at this time?" on an 11-point scale: range from 0= no pain to 10= worst possible pain; higher scores = worse pain. PID score: NPSR score at baseline (0 hour) minus NPSR score at each post-dose time point; overall possible PID score range at a post-dose time point: -10 to 10, higher positive value = greater improvement.

PID score: NPSR score at baseline (0 hour) minus NPSR score at each post-dose time point; overall possible PID score range at a single post-dose time point: -10 to 10, higher positive value = greater improvement in pain.
Measured: 0.25, 0.5, 1, 1.5, 2, 3, 4 5, 6, 7, and 8 hours post-dose on Day 1
Time to Onset of Achieving Meaningful Relief
When the participants were administered study medication at time 0 hours they were given the 2 stopwatches: 1 stopwatch was labelled as "first perceptible relief" and another as "meaningful relief." Participants were instructed to stop the stopwatch labelled as "meaningful relief" at the moment when they first experienced meaningful relief, that is, when the relief from the pain was meaningful to them. The stopwatch remained active for 8 hours (until stopped by the participants, or until rescue medication was administered).
Measured: Up to 8 hours post-dose on Day 1
Time to Onset of First Perceptible Relief
When the participants were administered study medication at time 0 hours they were given the 2 stopwatches: 1 stopwatch was labelled as "first perceptible relief" and another as "meaningful relief." Participants were instructed to stop the stopwatch labelled as "first perceptible relief" at the moment when they first began to feel any pain relieving effect. It was when they first felt a little/noticeable pain relief. It did not mean that they felt completely better (though they might), but when they first felt any difference in pain that they had at present. The stopwatch remained active for 8 hours (until stopped by the participants, or until rescue medication was administered).
Measured: Up to 8 hours post-dose on Day 1
Time to Treatment Failure
Treatment failure was defined as time to first dose of rescue medication or study discontinuation of the participants due to lack of efficacy.
Measured: Up to 8 hours post dose on Day 1

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 6 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 8 Apr 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 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 8 Apr 2019). 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 (PRR) and Pain Intensity Difference (PID) Scores From 0 to 8 Hours Post-dose (SPRID 0-8): Ibuprofen + Caffeine Versus Ibuprofen (time frame: From 0 to 8 hours post-dose on Day 1). 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 8 Apr 2019.
