- Have been receiving or have received chronic opioid therapy defined as greater than 15 morphine equivalents units per day for greater than 3 out of 7 days per week over a one-month period within 12 months of surgery.
- Use concurrent therapy that could interfere with the evaluation of efficacy or safety, such as any drugs which in the investigator's opinion may exert significant analgesic properties or act synergistically with N1539.
- Unable to discontinue medications, that have not been at a stable dose for at least 14 days prior to the scheduled bunionectomy procedure, within 5 half lives of the specific prior medication (or, if half life is not known, within 48 hours) before dosing with study medication.

- Be currently receiving treatment with oral meloxicam (Mobic®) within 7 days prior to surgery
- Have previously received N1539 in clinical trials, or had major surgery in the last 3 months that would interfere with study outcomes or increase the risk of study participation.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Summed Pain Intensity Difference Over the First 24 Hours (SPID24)
Time Frame: 24 Hours
|
Pain intensity was recorded using a Numeric Pain Rating Scale (Range 0-10) where 0 equates to no pain (better), and 10 equates to the worst pain imaginable (worse).
Pain intensity scores were to be recorded at the following time points: 0.25, 0.5, 0.75, 1, and 2 hours post Dose 1. Thereafter pain assessments were to be recorded every 2 hours until 48 hours post Dose 1. Pain intensity differences from baseline at each time point were calculated and a time weighted summed pain intensity difference (SPID) was then calculated.
Time weighted SPID calculations were computed by multiplying a weight factor to each score prior to summation.
The weight factor at each time point was the time elapsed since the previous observation.
A smaller SPID value (i.e. more negative) was better.

Time to First Dose of Rescue Analgesia
Time Frame: 48 Hours
|
Rescue analgesia (oral oxycodone 5 mg) was available to subjects with inadequately controlled pain upon request.
Time to first rescue was calculated as the elapsed time from administration of Dose 1 to the administration of the first dose of rescue analgesia.

Number of Doses of Rescue Analgesia Utilized Per Subject
Time Frame: 48 Hours

Time to Perceptible Pain Relief (TTPPR)
Time Frame: 12 Hours
|
Time to perceptible and meaningful pain relief was measured using the double stopwatch method.
For each randomized subject, two stopwatches were started immediately after administration of the first study dose (Hour 0).
The subject was to stop the first watch when they first perceived pain relief to occur (time to perceptible relief).
Once the first watch was stopped, the second stopwatch was given to the subject with the instructions to stop the watch when they first experienced meaningful pain relief (time to meaningful relief).

Time to perceptible and meaningful pain relief was measured using the double stopwatch method.
For each randomized subject, two stopwatches were started immediately after administration of the first study dose (Hour 0).
The subject was to stop the first watch when they first perceived pain relief to occur (time to perceptible relief).
Once the first watch was stopped, the second stopwatch was given to the subject with the instructions to stop the watch when they first experienced meaningful pain relief (time to meaningful relief).

Subjects With ≥ 30% Improvement in Pain From Baseline to Hour 6
Time Frame: 6 Hours
|
Percent improvement in pain is the cumulative pain intensity percent reduction from baseline over the defined interval (6 or 24 hours), calculated as SPID for the defined interval (SPID6 or SPID24) divided by the baseline pain intensity (BaselinePI) extrapolated across that interval.
Example: % Improvement through Hour 6 = 100 * SPID6 / (BaselinePI * 6 * 60), and SPID6 < 0 as an indication for improvement.
|
6 Hours
|
Subjects With ≥ 50% Improvement in Pain From Baseline to Hour 6
Time Frame: 6 Hours
|
Percent improvement in pain is the cumulative pain intensity percent reduction from baseline over the defined interval (6 or 24 hours), calculated as SPID for the defined interval (SPID6 or SPID24) divided by the baseline pain intensity (BaselinePI) extrapolated across that interval.
Example: % Improvement through Hour 6 = 100 * SPID6 / (BaselinePI * 6 * 60), and SPID6 < 0 as an indication for improvement.
