Suzetrigine added to multimodal opioid-sparing pain care for heart and weight-loss surgery

Official title: Suzetrigine-enhanced MultimOdal Opioid-sparing THerapy in Cardiac and Bariatric SURGery

Run by Icahn School of Medicine at Mount Sinai · NCT07539623 · Data updated 2026-11-12

This trial will test whether adding suzetrigine to standard multimodal pain care lowers opioid use and pain after bariatric or open-heart (sternotomy) surgery in adults.

Is this trial a fit for you?

Likely a good fit

Adults 18–85 scheduled for elective bariatric surgery (laparoscopic or open) or cardiac surgery via sternotomy who are opioid-naïve, able to consent, and not taking contraindicated CYP3A inhibitors or inducers are ideal candidates.

Probably not a fit

Patients having urgent or emergent surgery, ASA class V, chronic opioid users or those with substance use disorder, reoperations, or those taking contraindicated CYP3A modulators are unlikely to benefit or be eligible.

What this trial studies

This is a prospective, randomized, phase 3 study comparing suzetrigine versus placebo added to an established multimodal analgesic regimen for adults undergoing bariatric surgery or cardiac surgery via sternotomy. Participants aged 18–85 who are scheduled for elective procedures and who are not chronic opioid users or have substance use disorder will be enrolled and randomized. The main outcomes are post-operative opioid consumption and pain scores, with exclusions for urgent/emergent cases, ASA class V, reoperation, and concomitant use of strong/moderate CYP3A inhibitors or inducers. The trial is conducted at Mount Sinai Morningside and follows participants through the immediate post-operative period for analgesic outcomes.

Why it matters

Potential benefit: If successful, adding suzetrigine could reduce the need for opioids after surgery and lower post-operative pain and opioid-related side effects.

How similar studies have gone: Multimodal opioid-sparing approaches have previously reduced opioid needs after surgery, but adding suzetrigine is a novel approach with limited published clinical data to date.
