Clinical Trial Summary

This is a research study testing SABER-Bupivacaine (an experimental pain-relieving medication). SABER-Bupivacaine is designed to continuously deliver bupivacaine, a common local anesthetic, for a few days in order to treat local post-surgical pain. The purpose of this study is to investigate safety (side effects) associated with the use of SABER-Bupivacaine and how well it works in reducing pain and opioid-related side effects following various kinds of abdominal surgeries.

• Patients with known hypersensitivity to morphine
• Patients with conditions contraindicated for use of opioids
• Patients with atrial fibrillation/flutter or other non-sinus rhythm (including paced rhythm); left bundle branch block (LBBB); or the following conditions: right bundle branch block (RBBB) in presence of a cardiac disease, significant cardiomyopathy, and myocardial infarction within last 6 months
• Patients with a serum creatinine level two times more than the local laboratory normal limit
• Patients who have received greater than 600 mg morphine equivalent daily dose for three or more days per week in the month prior to the surgical procedure
• Patients who are currently being treated with methadone, or history of methadone use within the previous 6 months
• Patients with known or suspected abuse of opioids or other illicit drugs
• Patients with known or suspected alcohol abuse
• Participation in another clinical trial at the same time or within 30 days of this trial
• Patients who, in the Investigator's opinion, should not participate in the trial or may not be capable of following the trial schedule for any reason

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mean Pain Intensity on Movement	Mean pain intensity on movement AUC (time-normalized AUC) during the period 0 to 72 hours post-dose. Pain intensity was assessed with a standard 0 to 10 numeric rating scale (NRS), where no pain at all was rated as 0 and the worst pain imaginable was rated as 10. The AUC is computed for each patient using the standard trapezoidal rule and normalised by dividing by the time interval over which it is computed. This normalisation converts the AUC to the natural pain scale (NRS 0-10) to allow for better translation of the clinical treatment effect magnitude.	0 to 72 hours post-dose
Primary	Supplemental Opioid Use	Total morphine-equivalent dose during 0-72 hours post dose. Median values were presented because data was not normally distributed.	0-72 hours post dose
Secondary	Mean Pain Intensity on Movement	Mean pain intensity on movement AUC (time-normalized AUC) during the period 0 to 48 hours post-dose. Pain intensity was assessed with a standard 0 to 10 numeric rating scale (NRS), where no pain at all was rated as 0 and the worst pain imaginable was rated as 10. The AUC is computed for each patient using the standard trapezoidal rule and normalised by dividing by the time interval over which it is computed. This normalisation converts the AUC to the natural pain scale (NRS 0-10) to allow for better translation of the clinical treatment effect magnitude.	0 to 48 hours post-dose
Secondary	Total Morphine-equivalent Dose	Total morphine-equivalent dose during 0-48 hours post dose.	0-48 hours post dose
Secondary	Proportion (Percent) of Patients Who Have Evidence of a Wound Infection	From Surgical Wound Healing and Local Tissue Condition Evaluation	0 to 14 days post-dose (Visits 3 and 4)
Secondary	Time-to-first Use of Opioid Rescue Medication		0 to 14 days post-dose (Time from extubation until first opioid use)
Secondary	Number (Incidence) of Participants With Opioid-related Side Effects	AEs include: nausea, vomiting, constipation, dizziness, somnolence, urinary retention, respiratory depression	0 to 30 days post-dose
Secondary	Pain Intensity at Rest AUC During 0-72 Hours Post Dose	Mean pain intensity at rest AUC during the period 0 to 72 hours post-dose. Pain intensity was assessed with a standard 0 to 10 numeric rating scale (NRS), where no pain at all was rated as 0 and the worst pain imaginable was rated as 10.
