Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| SPID48 | 0 to 48 hours | SPID48: Time-weighted Sum of the Pain Intensity Difference (SPID) as recorded on an NRS (Numeric Rating Scale, 0 =no pain to 10 =worst possible pain) at rest 0 to 48 hours after the first dose of study drug. The score range was -480 (worst score) to 480 (best score). |
Secondary
| Measure | Time frame |
|---|---|
| Number of participants with treatment-related adverse events as assessed by CTCAE v5.0 | Day 1 to Day 30 |
