Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Overall Summed Pain Intensity Difference (SPID)
Participants assessed Pain Intensity (PI) using a 0-10 numeric pain rating scale (NPRS) where 0 is no pain and 10 is worst pain imaginable. PI was assessed 17 times within 24 hours after the first study dose, and immediately before any rescue medication and/or at early termination. The participant's baseline PI was subtracted from the timepoint PI, to derive a Pain Intensity Difference (PID) for each timepoint. Overall Summed Pain Intensity Difference (SPID) measures pain intensity change relative to baseline over the 24 hour period after dosing, and corresponds to the Area Under the Curve (AUC) of the PID. In this study, higher positive Overall SPID indicates better pain improvement. Overall SPID could range from -120 to 240. Two hour windowed last observation carried forward was used as applicable where PI score obtained before a rescue medication replaced PI score for each timepoint within 2 hours following rescue dose.
Time frame: 24 hours after the first dose
Pain Intensity Using a Numeric Pain Rating Scale Utilizing 2-hour Windowed Last Observation Carried Forward (W2LOCF)
10 point scale, where 0 is no pain and 10 is the worst pain imaginable; 2-hour windowed last observation carried forward (W2LOCF) utilizes "pain right now" just prior to rescue medication use and censors subsequent pain intensity values for 2 hours when calculating SPIDs
Time frame: 24 hours after the first dose
Total Pain Relief
Pain relief was assessed by participants using a 5 point scale, where 0 = none, 1 = slight, 2 = moderate, 3 = good or a lot, and 4 = complete. Pain relief was measured 17 times within 24 hours after the first study medication dose, and immediately before any rescue medication and/or at the time of early termination. Two-hour windowed last observation carried forward approach was used whereby the pain relief score obtained before a given rescue medication was carried forward to replace the pain relief scores collected at each observation timepoint within 2 hours following the rescue dose. Total pain relief (TOTPAR) had Areas Under the Curve (AUCs) calculated for each time point. The range for 24 hours post dose TOTPAR AUC was 0 to 96. Higher positive values indicate a better outcome with larger pain improvements.
Time frame: 24 hours after the first dose
Pain Relief: Number and Percentage of Subjects With Perceptible and Meaningful Pain Relief
The time to onset of first perceptible relief was defined as the post dose time at which the subject first begins to feel pain relief. The time to meaningful pain relief was defined as the post dose time at which the subject begins to feel meaningful pain relief. The assessments of perceptible and meaningful pain relief were ceased when rescue medication was taken.
Time frame: 24 hours after the first dose

Ran from Sep 2020 to primary completion in Dec 2020, 2 months.
Results were first posted in Aug 2022, 1 year 7 months after primary completion.
Of 62 industry-sponsored phase 2 interventional studies under Pain, half reached primary completion within 8 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 19. This study's 2 months is below that.
Counting every sponsor, half of 186 studies reached it within 21 months; a quarter within 7 and three quarters within 40.
