This randomized clinical trial will compare suzetrigine with standard analgesia for postoperative pain management after skin cancer surgery. Adults undergoing Mohs micrographic surgery or wide local excision for cutaneous malignancy or a skin-cancer precursor lesion of the head and neck will be randomized to suzetrigine monotherapy or scheduled acetaminophen plus ibuprofen for 72 hours after surgery. The study uses a double-blind, double-dummy design, and breakthrough oxycodone may be prescribed in either arm on request after same-day clinical assessment. The primary objective is to determine whether suzetrigine controls acute postoperative pain as well as scheduled acetaminophen plus ibuprofen during the first 24 hours after the first dose. Secondary outcomes include rescue opioid consumption, pain through 48 and 72 hours, satisfaction with pain control, functional recovery, adverse events, surgical bleeding, wound-healing complications, and blinding integrity.
Postoperative pain after Mohs micrographic surgery and wide local excision is commonly managed with non-opioid analgesics, including acetaminophen and ibuprofen. However, some patients undergoing skin cancer surgery are older, medically complex, or receiving antithrombotic therapy, and postoperative analgesic choices may be limited. Suzetrigine is an FDA-approved non-opioid analgesic for moderate to severe acute pain in adults and may provide an alternative postoperative pain strategy. This study is a prospective, randomized, double-blind, double-dummy, active-controlled, parallel-group Phase IV trial. Adults undergoing Mohs micrographic surgery or wide local excision for cutaneous malignancy or a skin-cancer precursor lesion of the head and neck requiring layered or more complex reconstruction will be enrolled at four M Health Fairview dermatologic surgery clinics in Minnesota. Participants will be randomized 1:1 after surgery to receive either suzetrigine monotherapy or scheduled acetaminophen plus ibuprofen for 72 hours. Participants in the suzetrigine arm will receive a 100 mg loading dose followed by 50 mg every 12 hours through 72 hours. Participants in the standard analgesia arm will receive acetaminophen 1000 mg every 8 hours plus ibuprofen 400 mg every 6 hours through 72 hours. Matching placebo capsules will be used so that the two regimens are identical in appearance, capsule count, and dosing schedule. Breakthrough oxycodone 5 mg every 6 hours as needed may be prescribed in either arm if a participant reports inadequately controlled pain and is assessed by a responsible clinician. Oxycodone is prescribed through routine clinical care and is not supplied automatically as study medication. Participants will complete electronic or paper diary assessments from baseline through Day 7, with a Day 30 safety survey and routine clinical record review through 90 days after surgery. The primary endpoint is the time-averaged area under the curve of Numeric Pain Rating Scale scores over the first 24 hours after the first dose, expressed as change from baseline, and tested for non-inferiority. Secondary outcomes include rescue opioid consumption, pain through 48 and 72 hours, patient-reported recovery and satisfaction, adverse events, wound-healing complications, surgical bleeding, and blinding integrity.

Participants will receive suzetrigine 100 mg orally once as a loading dose in clinic after surgery, followed by suzetrigine 50 mg orally every 12 hours through 72 hours. Matching placebo capsules will be used at intervening dosing times to preserve blinding.
Participants will receive acetaminophen 1000 mg orally every 8 hours plus ibuprofen 400 mg orally every 6 hours through 72 hours after surgery. Matching placebo capsules will be used at suzetrigine dosing times to preserve blinding.

Time-Averaged Numeric Pain Rating Scale Area Under the Curve Over 24 Hours
The primary endpoint is the time-averaged area under the curve of Numeric Pain Rating Scale scores from 0 to 10 over the first 24 hours after the first study dose, expressed as change from baseline. The endpoint will be tested for non-inferiority of suzetrigine compared with scheduled acetaminophen plus ibuprofen.
Time frame: Baseline through 24 hours after first study dose
Rescue Opioid Consumption Within 24 Hours
Rescue opioid consumption will be measured as total oxycodone use in morphine milligram equivalents within the first 24 hours after the first study dose.
Time frame: Baseline through 24 hours after first study dose
Time-Averaged Numeric Pain Rating Scale Area Under the Curve Over 48 Hours
Pain over 48 hours will be assessed using the time-averaged area under the curve of Numeric Pain Rating Scale scores from 0 to 10, expressed as change from baseline.
Time frame: Baseline through 48 hours after first study dose
Time-Averaged Numeric Pain Rating Scale Area Under the Curve Over 72 Hours
Pain over the 72-hour treatment course will be assessed using the time-averaged area under the curve of Numeric Pain Rating Scale scores from 0 to 10, expressed as change from baseline.
Time frame: Baseline through 72 hours after first study dose
Maximum Numeric Pain Rating Scale Score
Maximum postoperative pain will be assessed using the highest Numeric Pain Rating Scale score reported during the 72-hour treatment course.
Time frame: Baseline through 72 hours after first study dose
Adequacy of Pain Control
Adequacy of pain control will be assessed using participant-reported yes or no responses at 24 and 48 hours after the first study dose.
Time frame: 24 and 48 hours after first study dose
Patient Global Impression of Change
Participant-reported overall change after surgery will be assessed using the Patient Global Impression of Change at 48 hours and Day 7.
Time frame: 48 hours and Day 7 after first study dose
Satisfaction With Pain Control
Participant satisfaction with pain control will be assessed at the end of the 72-hour study medication course and at Day 7.
Time frame: 72 hours and Day 7 after first study dose
Activities of Daily Living
Functional recovery will be assessed using participant-reported activities of daily living at 24 hours and Day 7.
Time frame: 24 hours and Day 7 after first study dose
Adverse Events and Serious Adverse Events
Adverse events and serious adverse events will be collected through diary surveys, safety surveys, routine clinical care, and study safety review through Day 30.
Time frame: Baseline through Day 30 after surgery
Surgical Bleeding and Wound-Healing Complications
Surgical bleeding and wound-healing complications will be assessed using participant reports, clinical follow-up, and routine record review through 90 days after surgery.
Time frame: Baseline through 90 days after surgery
Study Drug Discontinuation Due to Adverse Events
Study drug discontinuation due to adverse events will be assessed during the 72-hour study medication course.
