Eligibility
Inclusion criteria

Exclusion criteria
* Participated in another oliceridine clinical study. * Received any investigational drug, device or therapy within 35 days before surgery. * Clinically significant medical, surgical, postsurgical, psychiatric or substance abuse condition or history of such condition that could confound the interpretation of efficacy, safety or tolerability data in the study. * American Society of Anesthesiologists (ASA) Physical Status Classification System classification III or worse.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| SPID-48 | 48 hours | Sum of Pain Intensity Difference over 48 hours (SPID-48), calculated from pain intensity scores measured using the Numeric Rating Scale (NRS; 0-10 points), where 0 indicates no pain and 10 indicates the worst possible pain. SPID-48 represents the time-weighted sum of pain intensity differences from baseline across the 48-hour assessment period. Higher SPID-48 values indicate greater pain relief (better outcome). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Responder rate | 48 hours | A patient is a responder if their final time-weighted Sum of Pain Intensity Differences from baseline (SPID-48) corresponds to, or is greater than, a 30% improvement. |
| Time to rescue pain medication use | 48 hours | — |
| Proportion of rescue pain medication use | 48 hours | — |
| Total rescue pain medication use | 48 hours | — |
