NCT07222072

Brief Summary

The investigators propose a randomized, triple-blinded (patients, investigators, outcomes assessors), placebo-controlled pilot feasibility trial (Methadone to End Narcotic Dependence, MEND trial) to assess the feasibility and safety of postoperative oral methadone in patients undergoing spine surgery and collect preliminary data to inform a larger clinical trial that will test the opioid-sparing effects of methadone at 3 months after spine surgery.

Outcome Measures

Primary Outcomes (5)

  • Feasibility and Acceptability-Participant Willingness/Recruitment

    Willingness of participants to be randomized Indicates acceptability of randomization among eligible patients Outcome Measure: % of eligible patient consenting to randomization

    7 days

    Feasibility, acceptability and execution of clinical protocol based on the use of intraoperative IV methadone followed by a postoperative oral methadone regimen following spine surgery will be assessed by yes/no response to the following: Willingness of neurosurgeons/anesthesiologists to buy in to the trial Reflects institutional buy-in and clinical integration potential Outcome Measure: % of surgeons permitting patient enrollment and supporting protocol adherence

    7 days

  • Feasibility and Execution-Protocol Compliance and Execution

    Feasibility of clinical protocol based on the use of intraoperative IV methadone followed by a postoperative oral methadone regimen following spine surgery will be assessed by yes/no response to the following: Compliance with the protocol, including specific study related procedures and timepoints specific to medication administration, adverse event reporting and data collection. Demonstrates deliverability and data reliability Outcome Measure: % adherence to all major protocol steps (drug administration, ECGs, AE reporting, opioid data)

Masking Details
Patients will be randomized 1:1 to postoperative methadone versus placebo on arrival to the operating room. Randomization will occur using a computer-generated randomization system in REDCap, with the sequence of randomly sized blocks pre-determined using the PLAN Procedure in SAS statistical software, stratified by previous history of opioid use (Opioid naïve versus those taking opioids before surgery).
