A Health Economic Trial in Adult Patients Undergoing Open Colectomy MA402S23B302 (IMPROVE-Open)

This study has been terminated.
(Slow enrollment.)

Pacira Pharmaceuticals, Inc Identifier:
First received: October 24, 2011
Last updated: January 19, 2014
Last verified: January 2014
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.

Condition Intervention Phase
Bowel Obstruction Drug: IV morphine sulfate Drug: EXPAREL (bupivacaine liposome injectable suspension) Phase 4

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Health Services Research
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

Primary Outcome Measures:
  • Total Opioid Burden [ Time Frame: Wound closure to time hospital discharge order written or Day 30, whichever is sooner ]
    Total opioid consumed (IV and PO) postsurgically until the hospital discharge order is written or through Day 30, whichever is sooner.

  • Health Economic Benefits [ Time Frame: Wound closure to Day 30 ]
    1. Total cost of hospitalization until the time hospital discharge order is written or through Day 30, whichever is sooner.
    2. 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.

Secondary Outcome Measures:
  • Incidence of Opioid-related Adverse Events and Patient Satisfaction With Postsurgical Analgesia. [ Time Frame: Wound closure to time hospital discharge order written or Day 30, whichever is sooner. ]
    1. 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.
    2. Responses to one question pertaining to patient satisfaction with postsurgical analgesia and four questions pertaining to postsurgical recovery following hospital discharge.

Enrollment: 5

Study Completion Date: July 2012
Primary Completion Date: July 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: IV morphine sulfate
morphine sulfate (or Sponsor-approved equivalent)
Drug: IV morphine sulfate
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.
Other Name: morphine sulfate (or Sponsor-approved equivalent)
Experimental: EXPAREL
EXPAREL (bupivacaine liposome injectable suspension)
Drug: EXPAREL (bupivacaine liposome injectable suspension)

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.

Other Name: bupivacaine free base

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.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

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).
