A Health Economic Trial in Adult Patients Undergoing Open Colectomy MA402S23B302

Study Overview
=================
Brief Summary
-----------------
This study is designed to compare the standard of care against EXPAREL (bupivacaine liposome extended-release injectable suspension) to determine if total opioid consumption is reduced when using EXPAREL, therefore possibly reducing total hospitalization costs.

Detailed Description
-----------------
This is a phase 4, prospective, sequential, open-label study designed to evaluate the efficacy, safety, and health economic benefits of intraoperative local wound infiltration with EXPAREL (bupivacaine liposome extended-release injectable suspension), compared with postsurgical administration of standardized intravenous (IV) morphine sulfate, for postsurgical analgesia in adult patients undergoing open colectomy with general anesthesia.

Official Title
-----------------
A Pain Relief Trial Utilizing the Infiltration of a Multivesicular Liposome Formulation Of Bupivacaine, EXPAREL®: A Phase 4 Health Economic Trial in Adult Patients Undergoing Open Colectomy

Conditions
-----------------
Bowel Obstruction

Intervention / Treatment
-----------------
* Drug: IV morphine sulfate
* Drug: EXPAREL (bupivacaine liposome injectable suspension)


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Male or female, 18 years of age or older. Patients scheduled to undergo open segmental colectomy with planned primary anastamosis, as defined by cecectomy, right hemicolectomy, resection of transverse colon, left hemicolectomy, or sigmoidectomy. Ability to provide informed consent, adhere to study visit schedule, and complete all assessments. Exclusion Criteria: Patients with a history of hypersensitivity or idiosyncratic reactions or intolerance to any local anesthetic, opioid, or propofol. Patients who abuse alcohol or other drug substance. Patients with severe hepatic impairment. Patients currently pregnant or who may become pregnant during the course of the study. Patients with any psychiatric, psychological, or other condition that the Investigator feels may make the patient an inappropriate candidate for this clinical study. Patients who have participated in a EXPAREL study within the last 30 days. Patients who have received an investigational drug within 30 days prior to study drug administration, or planned administration of another investigational product or procedure during the patient's participation in this study. Patients who undergo any concurrent surgical procedure during the ileostomy reversal surgery. In addition, the patient will be ineligible if he/she meets the following criteria during surgery: Patients with unplanned multiple segmental resections or large intestine. Patients who have unplanned, temporary or permanent colostomies, ileostomies, or the like placed. Patients who receive intraoperative administration of opioids (other than fentanyl or analogs) or an other analgesic, local anesthetics, or anti-inflammatory agents. Patients who receive Entereg(R).

Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: IV morphine sulfate<br>morphine sulfate (or Sponsor-approved equivalent) | Drug: IV morphine sulfate<br>* Patients in this group will receive IV morphine sulfate via patient-controlled analgesia (PCA) pump, as needed. The PCA pump will be set up postsurgically as soon as possible and prior to the patient leaving the post-anesthesia care unit (PACU) or immediately upon transfer to the floor if the stay in the PACU is less than 1 hour.<br>* Other names: morphine sulfate (or Sponsor-approved equivalent);|
| Experimental: EXPAREL<br>EXPAREL (bupivacaine liposome injectable suspension) | Drug: EXPAREL (bupivacaine liposome injectable suspension)<br>* Patients in this group will receive 266 mg EXPAREL diluted with preservative free 0.9% normal saline to a total volume of 30 cc and administered via wound infiltration prior to wound closure. When not contraindicated, 30 mg IV ketorolac, a non-steroidal anti-inflammatory drug (NSAID), may be substituted per the site's standard of care. All patients will be offered rescue analgesia, as needed.<br>* Other names: bupivacaine free base;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Total Opioid Burden | Total opioid consumed (IV and PO) postsurgically until the hospital discharge order is written or through Day 30, whichever is sooner. | Wound closure to time hospital discharge order written or Day 30, whichever is sooner | 
| Health Economic Benefits | Total cost of hospitalization until the time hospital discharge order is written or through Day 30, whichever is sooner. Length of stay (LOS), recorded in hours, defined as the time of completion of the wound closure until the hospital discharge order is written or through Day 30, whichever is sooner. | Wound closure to Day 30 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incidence of Opioid-related Adverse Events and Patient Satisfaction With Postsurgical Analgesia. | Incidence of opioid-related adverse events defined as somnolence, respiratory depression, hypoventilation, hypoxia, dry mouth, nausea, vomiting, constipation, sedation, confusion, pruritus, urinary retention, and postoperative ileus. Responses to one question pertaining to patient satisfaction with postsurgical analgesia and four questions pertaining to postsurgical recovery following hospital discharge. | Wound closure to time hospital discharge order written or Day 30, whichever is sooner. |
