Precision Pain Management - A Randomized Clinical Trial Assessing the Efficacy of Suzetrigine on Postoperative Analgesia Among Surgical Patients at Higher Risk for Persistent Postoperative Opioid Use (POU)
What this study is about
The purpose of the study is to investigate the effectiveness of suzetrigine for treatment of acute postoperative pain among surgical patients identified as high risk for persistent postoperative opioid use (POU).
View original scientific description
The purpose of the study is to investigate the efficacy of suzetrigine for treatment of acute postoperative pain among surgical patients identified as high risk for persistent postoperative opioid use (POU). Using a validated artificial intelligence predictive model (termed SurgNet-POU) developed by the PI, electronic health record (EHR) data will be queried from all prospective surgical patients undergoing orthopedic surgery and inputted into the model to predict risk of POU (defined as requiring opioids ≥ 3 months after surgery). Those identified as high risk by the SurgNet-POU will be eligible candidates for this study. Suzetrigine (Vertex Pharmaceuticals) is an FDA-approved non-opioid oral analgesic that acts as a selective Nav1.8 sodium channel blocker. It has been shown to have efficacy in post-surgical pain and has compared favorably to placebo and similar to some opioids, without the risk of addiction or other adverse events related to opioids. Consented participants will be randomized to one of two arms: (1) standard care (termed standard care) defined as usual prescribing outpatient opioid analgesic protocols per surgical team; versus (2) standard care combined with 14-day regimen of suzetrigine. Those randomized to the suzetrigine arm will receive 100mg suzetrigine PO \~ 1-2 hours prior to surgery and take 50mg po twice a day for 14 days postoperatively. The primary outcome will be total opioid consumption over 14 days postoperatively. Secondary outcomes include average, highest and lowest pain scores at 7, 14, 30, and 90 days after surgery; and opioid consumption at 7, 30, and 90 days after surgery.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Patients who are identified as high-risk for POU as calculated by our SurgNet-POU predictive deep learning model. The probability threshold will be set at \~\> 0.25. Potential participants will be screened prior to surgery by incorporating their electronic health record data in to the model.
- Patients undergoing major orthopedic surgery (hip arthroplasty, knee arthroplasty, shoulder arthroplasty, joint arthroscopy, foot/ankle surgery, upper extremity fracture surgery, spine surgery), breast surgery (mastectomy, breast reconstruction), gynecological surgery (hysterectomy, myomectomy), or abdominal surgery.
- Adult patients of at least 18 years of age
- Has the capacity to consent
Exclusion criteria
- Incarceration
- Patients with a previous history of opioid use disorder.
- Patients on fentanyl transdermal patch, methadone, and/or buprenorphine.
Where
- La Jolla, California
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
