Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

. Self-reported bedtime was between 9 pm and midnight on 4-7 nights per week.
Exclusion criteria
. Body mass index \> 32 as calculated from the participant's height (m) and weight (kg); weight (kg)/square height (m²)
. Presence of a sleep disorder, such as a diagnosis of insomnia, narcolepsy, sleep paralysis, active somnambulism (history of childhood somnambulism is accepted), hypnagogic/ hypnopompic hallucinations, and REM behavior disorder, will be excluded based on the clinical interview. For sleep apnea syndrome, an apnea-hypopnea index \> 15 per hour of sleep on the first screening night will be used as an exclusion criterion. For periodic limb movement disorder, an index of periodic limb movements during sleep associated with an arousal \> 15 per hour of sleep on the first screening night will be used as an exclusion criterion.
. History of epilepsy
. Any previous serious head injury or stroke
. Any evidence of psychiatric disorder (including Beck Depression Inventory \[BDI\] ≥ 20 at screening, or a score of 3 on item related to suicidal ideas)
. Evidence of any clinically significant, or unstable, acute or chronically progressive medical or surgical disorder (including planned medical procedures that may impact sleep), or any condition that may interfere with the absorption, metabolism, distribution, or excretion of the study drug, or may affect the participant's safety
. Clinically significant and abnormal electrocardiogram (ECG; including QTc ≥ 450 ms for males, 460 ms for females) or a history of cardiovascular disease including poorly controlled hypertension, ischemic heart disease, arrhythmia, or severe heart failure
