The Efficacy and Safety of NALDEBAIN for the Treatment of Post-Laparotomy Surgery

A Randomized Controlled Trial to Compare the Efficacy and Safety of NALDEBAIN With Intravenous Patient-Controlled Analgesia With Fentanyl for the Treatment of Post-Laparotomy Surgery

• Status: Unknown
• Phase: Phase 4

Summary

The primary objective of this study is to determine the safety and efficacy of single doses of intramuscular NALDEBAIN on patients scheduled to undergo elective laparotomy. This will be performed by administering NALDEBAIN pre-operatively to subjects scheduled to undergo elective laparotomy, and assessing the safety and efficacy of the drug compared to PCA with fentanyl. The study will demonstrate whether single use of NALDEBAIN is noninferior to PCA with fentanyl or not.

Detailed description

Screening (Days -30 to -1) (All Study Subjects) The nature of the study, as well as the potential risks and benefits associated with study participation, will be fully explained to all potential subjects. The following will then be obtained: * Informed consent. * Demographic information, including sex, age, BMI and type of surgery. * Vital signs, including temperature, respiratory rate, blood pressure and heart rate. * Medical history, including medication use and history of allergy. * Physical examination. * Laboratory testing, including hematological and biochemical tests, and urinalysis. * ECG and X-ray. Study Day -1 (All Eligible Subjects) * Eligible subjects will be required to check into the clinical site before surgery (Day -1). The following procedures will be performed upon check-in: * Review inclusion/exclusion criteria * Randomization * Review of concomitant medications * Review of adverse events * Additional laboratory tests will be requested as needed deciding by the investigator. * All eligible subjects will hospitalize and be randomized into one of two treatment groups: * Group 1 - Intramuscular NALDEBAIN. * Group 2 - Intravenous PCA with fentanyl. Group 1 will receive single dose of NALDEBAIN (150 mg Nalbuphine Sebacate) intramuscularly 24±12 hours before surgery. Group 2 will receive intravenous patient-controlled analgesia with fentanyl through 48 hours after surgery. * Pain assessment: group 1 and 2 will rate their pain intensity using a VAS pain scale prior dosing or at Day -1 respectively. * Brief Pain Inventory (BPI) will be evaluated at Day -1. * Vital signs will be checked prior to dosing and once daily before Day 6. * Group 1 received NALDEBAIN will evaluate injection site within 1 hour prior to dosing. Study Day 0-5 All subjects will be given general anesthesia prior to their scheduled surgical procedure. If patients need additional medication for treatment of pain, Ketorolac and Morphine could be used as supplemental analgesics when they needed. After surgery, the following evaluations will be performed: * Pain assessment: All subjects will rate their average pain intensity using a VAS pain scale. The assessment will perform before the first use of PCA or supplemental analgesics and at 4±1, 24±2, 32±3, 48±4 hours and once daily on Days 3 to Day 5 after the surgery. * Brief Pain Inventory (BPI) will be evaluated at Day 2. * Vital signs (temperature, respiratory rate, blood pressure and heart rate) will be checked once daily before Day 6. * In Group 1 (NALDEBAIN group), the injection site will be evaluated once daily before final visit. * Review of concomitant medication and adverse event record. * In Group 2 (PCA group), the amount of fentanyl used will be recorded on Days 0 through 2. Study Day 6 Evaluate the following items at Day 6. * Pain assessment: Subjects will rate their pain intensity in the patient diary. * Brief Pain Inventory (BPI) will be evaluated. * Vital signs (temperature, respiratory rate, blood pressure and heart rate) will be checked. * Injection site evaluation. * Review of the adverse event record. * Review of concomitant medication. Final Visit (Day of Discharge, Day 6\~30) * Vital signs (temperature, respiratory rate, blood pressure and heart rate) will be checked * Injection site evaluation * Laboratory tests, including hematological and biochemical tests, and urinalysis. * Patient satisfaction: At the final visit, each subject was asked the following question: "How satisfied were you with your postsurgical analgesia"? Subjects were asked to classify themselves as either "highly satisfied", "satisfied", "uncertain", "dissatisfied", or "very dissatisfied". * Physical examination. * Review of the adverse event record. * Review of concomitant medication.
