Inclusion criteria
. Male or female between 18 to 75 years of age, inclusive.
. Diagnosis of OSA according to the International Classification of Sleep Disorders, 3rd edition (ICSD-3) criteria.
. Patients with OSA may be considered for enrollment if they meet one of the following criteria:
. Use of a primary therapy for OSA (i.e., positive airway pressure (PAP), oral pressure therapy, oral appliance, or upper airway stimulator) on at least 1 night per week, or
. History of at least 1 month of an attempt to use one or more primary OSA therapies with at least one documented adjustment that was made in an attempt to optimize the primary OSA therapy, or participants who have never used and refuse to use a primary OSA therapy, or
. History of a surgical intervention intended to treat OSA symptoms.
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.
What they're measuring
1
To evaluate the effect of solriamfetol compared to placebo among patients with OSA in change from baseline to Week 12 in the mean MWT sleep latency (minutes, (determined from the first four 40-minute trials of the MWT)
Timeframe: From enrollment to the end of treatment at 12 weeks
2
To evaluate the effect of solriamfetol compared to placebo among patients with OSA in change from baseline to Week 12 in ESS scores
Timeframe: From enrollment to the end of treatment at 12 weeks
. A stable level of compliance with a primary OSA therapy for at least 1 month prior to the baseline visit as follows:
. A stable level of use of a primary OSA therapy, or
Exclusion criteria
. Female participants who are pregnant or lactating.
. Usual bedtime later than 1 a.m. (01:00).
. Occupation requiring nighttime shift work or variable shift work.
. Any other clinically relevant medical, behavioral, or psychiatric disorders other than OSA that is associated with excessive sleepiness.
. History or presence of bipolar disorder, bipolar related disorders, schizophrenia, schizophrenia spectrum disorder, or other psychotic disorders according to DSM-5 criteria, or presence of significant suicidality.
. History or presence of any acutely unstable medical condition, behavioral or cognitive impairment, or any medical condition or surgical history that could affect the safety of the participant or interfere with study efficacy, safety and PK assessments, or the ability of the participant to complete the study per the judgment of the investigator.
. History of the bariatric surgery within the past year or a history of any gastric bypass procedure.
. Presence of renal impairment or calculated creatinine clearance less than 60 mL/min at screening, which is calculated using the following formula: CLcr (mL/min) = (140 - age \[years\]) x body weight (kg) x (0.85, if female))/(72 x serum creatinine value \[mg/dL\]), if serum creatinine is expressed in µmol/L, the value should be divided by 88.4 to convert µmol/L to mg/dL.
