About this trial

Total hip and knee joint replacements are among the most common and painful orthopedic procedures performed worldwide, often requiring intensive analgesia to support early ambulation and recovery. Despite widespread use of multimodal regimens, many patients still rely on opioids, which can cause sedation, nausea, constipation, and long-term dependency. Evaluating Suzetrigine in this high-need population may improve recovery trajectories, reduce opioid consumption, and support enhanced recovery protocols. Given the growing surgical volume and the emphasis on opioid-sparing strategies, rigorous investigation of Suzetrigine's efficacy in joint replacement is of high clinical value. In this study, patients undergoing primary total hip replacement will be randomized to receive either Suzetrigine or placebo for seven days, with the loading dose administered prior to surgery. The primary outcome is cumulative 48-hour opioid consumption in oral morphine equivalents starting from entry into the post-anesthesia care unit (PACU).

Treatments tested in this trial

  • Suzetrigine

    Drug

    Suzetrigine is a new novel peripherally acting non-opioid pain medication recently approved by the FDA that exerts its analgesic effects by binding to the peripherally located Nav1.8 Sodium channel receptors present on peripheral nerves.

  • Placebo

    Other intervention

    This will be a placebo drug.

Treatment groups

Trial outcomes

Primary outcomes

1

Cumulative opioid consumption within the first 48 hours after THA starting from PACU entry (t=0), in oral morphine equivalents

The primary outcome is cumulative 48-hour opioid consumption in oral morphine equivalents starting from entry into the post-anesthesia care unit (PACU). This measure will be taken from EPIC via the MAR and documented in the study "MUD"; post-discharge, patient to report date/time of opioid use # of pills, dose in diary and documented in study "MUD". Measurements will be taken in PACU and 0-48 hrs following surgery.

Time frame
From entry into the post-anesthesia care unit (PACU) to 48 hours after THA surgery

Secondary outcomes

1

Post operative pain using Numeric Rating Scale (current at rest, with ambulation, worst & least in last 24 hours) - POD1-7

Post operative pain using Numeric Rating Scale (current at rest, with ambulation, worst \& least in last 24 hours). The Numeric Rating Scale is a simple, widely used tool for measuring pain intensity. It consists of a 0-10 point scale. This will be measured at post operative day 1 and upto post-operative day 7.

Time frame
From Post Anesthesia Care Unit to post op date 7
2

Numeric Rating Scale - PACU: average, least, worst

Numeric Rating Scale in Post-Anesthesia Care Unit (PACU) ranging from average to least to worst. Post operative pain using Numeric Rating Scale(current at rest, with ambulation, worst \& least in last 24 hours). The Numeric Rating Scale is a simple, widely used tool for measuring pain intensity. It consists of a 0-10 point scale. This will be measured after surgery in the PACU.

Time frame
From arrival in PACU until discharge criteria are met (expected duration up to 4 hours postoperatively).
3

Numeric Rating Scale @POD14, @week 6, @week 12 - average pain, worst & least: last 7 days; current

Numeric Rating Scale measured at 14 days following surgery, then at 6 weeks following surgery and then 12 weeks following surgery. Measurements will range from average pain to worst pain to least amount of pain over the last 7 days and current pain.

Time frame
From 14 days following surgery, 6 weeks from surgery and 12 weeks from surgery.
4

Cumulative Opioid consumption (Oral morphine equivalents = OME): PACU, 0-24hours, 0 to 168 hours (7 days postoperatively)

Cumulative Opioid consumption (Oral morphine equivalents = OME): Post anesthesia care unit (PACU) at 0 and 24hours and 168 hours (i.e. 7 days postoperatively). The primary outcome is cumulative consumption in oral morphine equivalents starting from entry into the post-anesthesia care unit (PACU). This measure will be taken from EPIC via the MAR and documented in the study "MUD"; post-discharge, patient to report date/time of opioid use # of pills, dose in diary and documented in study "MUD". Measurements will be taken in PACU, 0-24hrs, 0-48 hrs and 0-168hrs following surgery.

Time frame
from first time in PACU to 24hours after and then 168hours after
