Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Pain Intensity on Movement From 0-48 Hours Post-Treatment | Assessed from 0 to 48 hours post-dose, summary measure (see description) reported. | A derived measure computed based on a patient-reported numerical pain rating scale assessing pain as a whole number from 0 (no pain) to 10 (worst pain imaginable) when the subject sits up from a supine position. This measure was evaluated by electronic diary at 13 planned time points from 0 to 48 hours post-treatment. The values reported are mean pain scores for each treatment group. |
| Secondary | Pain Intensity Using the NPRS-11 With Movement | Assessed from 0 to 72 hours post-dose, summary measure (see description) reported. | A derived measure computed based on a patient-reported numerical pain rating scale assessing pain as a whole number from 0 (no pain) to 10 (worst pain imaginable) when the subject sits up from a supine position. This measure was evaluated by electronic diary at 17 planned time points from 0 to 72 hours post-treatment. The values reported are mean pain scores for each treatment group. |
| Secondary | Total IV Morphine-equivalent Dose of Rescue Opioids | 0-72 hrs. post dose (after surgery) | IV morphine-equivalent dose |
| Secondary | Composite Endpoint of Silverman's Integrated Analgesic (SIA) Assessment Score | 0 to 72 hours | Score of Integrated Analgesia (SIA) is a composite endpoint that integrates pain assessment scores with opioid use over various collections of timepoints by ranking the pain score and the opioid use separately across treatments. After the scores are computed the means are calculated across time points to provide a single overall treatment effect. The composite SIA score ranges from -200 to 200 with -200 being the best case and 200 the worst case. |
| Secondary | Subjects Not Taking Rescue Medication From PACU Discharge to 72 Hours | From PACU Discharge to 72 Hours post-treatment | Pooled SABER-Bupivacaine parts 1 + 2 vs. Bupivacaine HCl |
| Secondary | Time to First Opioid Rescue Medication Use After Discharge From the PACU | From PACU Discharge to 72 Hours post-treatment | Pooled SABER-Bupivacaine parts 1 + 2 vs. Bupivacaine HCl |
| Secondary | Time to PACU Discharge Eligibility as Assessed by Modified Post-Anesthesia Discharge Scoring System (mPADSS) | From admission to discharge from PACU (Approximately 0 to 12 hours) | mPADSS is a tool used to determine eligibility for discharge from the PACU after ambulatory surgery. It includes an assessment of parameters such as vital signs, activity level, nausea/vomiting, pain, and surgical bleeding. For this trial, evaluation of eligibility for PACU discharge by mPADSS has been slightly modified to provide a standardized means of assessing eligibility for PACU discharge across multiple investigative sites and also ensures that nonmedical complications, such as a missing ride home, do not interfere with evaluation of test drug effects. |
