Suzetrigine for Pain Management After Broken Hip Surgery

(STRIDE-HIP Trial)

The goal of this clinical trial is to learn whether suzetrigine (Journavx®), when added to standard multimodal pain management, can reduce opioid use while providing adequate pain control in adults undergoing surgery for an acute hip fracture. The study will enroll adults aged 18 years or older with femoral neck, intertrochanteric, pertrochanteric, or subtrochanteric hip fractures requiring operative treatment at Beth Israel Deaconess Medical Center. Although enrollment is open to adults aged 18 years and older, the study population is expected to consist predominantly of older adults.

The main questions the study aims to answer are:

* Does treatment with suzetrigine as part of multimodal pain therapy reduce postoperative opioid consumption, measured as morphine milligram equivalents (MME), during the index hospitalization through 72 hours after surgery or hospital discharge, whichever occurs first?

* Does suzetrigine provide effective postoperative pain control and have an acceptable safety and tolerability profile in adults undergoing hip fracture surgery? Researchers will compare participants receiving suzetrigine plus standard multimodal analgesia with matched historical BIDMC patients who underwent similar hip fracture surgery between 2020 and 2025 and received standard multimodal analgesia without suzetrigine. Historical controls will be matched on factors including age, sex, fracture type, surgery type, surgeon, ASA class, opioid-naïve status, regional anesthesia, and relevant comorbidities.

Participants in the prospective study will:

* Receive a 100-mg oral loading dose of suzetrigine before surgery, followed by 50 mg orally every 12 hours for up to 14 days or until pain resolves, whichever occurs first.

* Receive standard multimodal pain management, which may include acetaminophen, nonsteroidal anti-inflammatory medications when appropriate, regional anesthesia, and rescue opioid medication as clinically needed.

* Complete pain assessments during hospitalization and at follow-up time points, with opioid use recorded and converted to MME.

* Complete follow-up assessments at approximately Days 7, 14, and 28 after surgery, including pain, medication use, adverse events, treatment adherence, and patient-reported outcomes.

* Record study medication use, missed doses, rescue opioid use, and adverse events after hospital discharge when applicable.
