About this study
Official title: Intraoperative Methadone for Postoperative Pain Management in a Head and Neck Oncology Population - A Prospective, Randomized Controlled Trial
This phase IV trial compares how well methadone plus standard fentanyl given during surgery (intraoperative) works compared to intraoperative standard fentanyl alone in managing pain after surgery (postoperative) among patients with head and neck cancers. For most head and neck cancers, the standard treatment is surgery to remove the cancer followed by surgical reconstruction, which often requires tissue harvested from another part of the body-known as a "free flap tissue transfer". These procedures are highly complex, demand a two-surgeon team, and often take many hours to complete. The combination of multiple operative sites and extent of the surgery contributes to significant postoperative pain. Methadone is not yet used in the head and neck population but has been utilized in other subspecialties like spine and cardiac surgery. The benefits of methadone may include improved pain control in the first 72 hours postoperatively requiring less opioids postoperatively and improvement in overall pain scores. Giving intraoperative methadone plus standard fentanyl may work better than fentanyl alone in managing postoperative pain among patients with head and neck cancers.
Read the detailed description
PRIMARY OBJECTIVE:
- To assess the effectiveness of intraoperative methadone compared to control in reducing the requirements of morphine milliequivalents (MMEs).
SECONDARY OBJECTIVES:
- To assess the effectiveness of intraoperative methadone compared to control in reducing objective measures of pain, including MMEs, for up to 72 hours postoperatively.
II. To assess how soon after surgery patients require additional opioid administration for those in the methadone group compared to control.
III. To assess whether additional pain management is required less frequently in the methadone group compared to control.
EXPLORATORY OBJECTIVES:
- To assess if there is an increase in the incidence of post-operative emesis events in the methadone group compared to the control.
II. To assess the effectiveness of intraoperative methadone compared to control on patient's pain scores daily.
III. To assess whether there is a difference in respiratory status between the methadone group compared to the control.
IV. To assess whether higher rates of naloxone administration are required in the methadone group.
- To assess if pain control impacted acute recovery more effectively in the methadone group compared to control.
VI. Clinical outcomes that are standard of care may be assessed. VII. To assess if there is any impact on pain at ~1 month postoperatively compared to the control group.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive methadone intravenously (IV) at the time of incision during standard of care (SOC) surgery. Patients also receive SOC fentanyl prior to SOC laryngoscopy procedure.
ARM II: Patients receive SOC fentanyl prior to SOC laryngoscopy procedure and surgery.
After completion of study intervention, patients are followed up at 4-6 weeks.

What is being measured
The primary outcome is the main question the study is designed to answer.
Total morphine milligram equivalents (MMEs) administered in the first 24 hours postoperatively
MMEs will be calculated using the Stanford Opioid Equivalent calculator and data is obtained from the medication administration record (MAR) in epic. Out of room is standard terminology for when the patient leaves the operating room and a required timestamp per standard workflows across all institutions. Two-sided two-sample t-test will be used to compare mean MMEs administered in the first 24 hours between the methadone and control groups. If data is right skewed, log transformation will be performed prior to t-test. If severe violation to normality assumption is detected graphically or by Shapiro-Wilk hypothesis test, Wilcoxon rank-sum test will be performed instead.
Measured: From out of room to 24 hours postoperatively
Secondary outcomes (3)
Cumulative MMEs between 24-48 hours postoperatively and 48-72 hours postoperatively
Will be analyzed as the same approaches as the primary endpoint with two-sided two-sample t-test. If data is right skewed, log transformation will be performed prior to t-test. If severe violation to normality assumption is detected graphically or by Shapiro-Wilk hypothesis test, Wilcoxon rank-sum test will be performed instead.
Measured: From 24 hours postoperatively to 72 hours postoperatively
Time to first dose of oral opioid administered & intravenous opioid administered
Will be assessed using a time-to-event analysis (log-rank test) to compare between the two groups.
Measured: From out of room to discharge, an average of 5 days
Acute pain service (APS) consult placement (Yes/No) and outcome of that consult
Chi-squared test (or Fisher's exact test if any expected count is < 5) will be used to compare proportion of APS placement between the two groups. Chi-squared test (or Fisher's exact test if any expected count is < 5) will be used to assess the ambulatory goals comparing the proportion of goals achieved between the two groups on each post-operative day (POD) period. (POD0, POD1 and POD2).
Measured: From out of room to discharge, an average of 5 days

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
