Run by University of Rochester · NCT07217912 · Data updated 2026-11-12

This study will test whether taking daridorexant the first three nights after heart surgery can reduce postoperative delirium and improve sleep in people aged 60 and older.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are people aged 60 or older having surgical aortic valve replacement or coronary artery bypass grafting at the University of Rochester's Strong Memorial Hospital who can consent and complete English-language assessments.

Probably not a fit

Patients with baseline delirium or dementia-level cognitive impairment, those undergoing emergency or repeat cardiotomy, people with severe liver or kidney dysfunction, or those taking contraindicated medications or regular prescription sleep aids are unlikely to benefit from this protocol.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a randomized, placebo-controlled pilot trial of daridorexant 50 mg given each of the first three nights after surgical aortic valve replacement or coronary artery bypass grafting. Participants complete a baseline visit, receive daridorexant or placebo in the hospital, and are evaluated daily for delirium symptoms and sleep during the first three postoperative days. The protocol includes an optional wrist-worn sleep monitor to collect objective sleep data in the postoperative setting. The trial follows a prior feasibility effort and is intended to generate preliminary effect estimates to plan a larger phase 2b trial.

Why it matters

Potential benefit: If successful, the drug could reduce the incidence and severity of postoperative delirium and improve sleep quality after cardiac surgery.

How similar studies have gone: Using an orexin receptor antagonist to prevent postoperative delirium is a novel application, though a prior feasibility study at the same center supported conducting this randomized pilot and daridorexant is already approved for treating insomnia.
