What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Idiopathic hypersomnia severity scale (IHSS) score

    IHSS is a tool used to measure the severity of the symptoms experienced by patients with IH during the previous month. The IHSS includes 2 items (1 and 2) on nighttime sleep duration and quality, 3 items (3, 4, and 5) on sleep inertia and sleep drunkenness after nighttime sleep and 1 (8) after daytime nap, and 3 items (6, 7, and 9) on diurnal symptoms (nap occurrence, daytime sleepiness). Items 10-14 assess daytime functioning alterations due to hypersomnolence. Six items are scored on a 3-point Likert scale and 8 items on a 4-point Likert scale; the Likert scale is a point scale that is used to allow the individual to express how much they agree or disagree with a particular statement. The total IHSS score is the sum of all item scores (range: 0-50), and higher scores indicate more severe symptoms.

    Measured: From baseline to week 7

Secondary outcomes (14)
  1. Epworth Sleepiness Scale (ESS) score

    ESS is a short 8-item questionnaire designed to assess daytime sleepiness. Participants assign a score from 0 to 3 (0 = never; 1 = weak; 2 = moderate; 3 = strong).The minimum score is 0 and the maximum score is 24.

    Measured: From baseline to week 7

  2. Maintenance of Wakefulness Test (MWT)

    MWT is used in this study to assess an individual's ability to maintain awake while resisting the pressure to fall asleep. Patients will be administrated four 40-minute MWT session at 2 hours interval at baseline visit 2 (Day 14) and at endpoint visit (Day 35), according to validated standard. The changes in MWT will be compared between the treatment groups.

    Measured: From baseline to week 7

  3. Psychomotor vigilance task (PVT)

    PVT is a widely utilized as a measure of behavioral alertness, primary due to its high sensitivity to sleep deprivation and its psychometric advantages over other cognitive tests. The standard 10-min PVT measures sustained or vigilant attention by recording response times (RT) to visual (or auditory) stimuli presented at random inter-stimulus intervals.

    Measured: From baseline to week 7

  4. Karolinska Sleepiness Scale (KSS)

    KSS measures the subjective level of sleepiness at a particular time during the day. On this scale subjects indicate which level best reflects the psycho-physical sate experienced in the last 10 min. The KSS is a measure of situational sleepiness.

    Measured: From baseline to week 7

  5. Sleep inertia questionnaire

    The Sleep inertia questionnaire evaluated self-reported sleep inertia and sleep drunkenness on the day of the PVT assessment, utilizing wording similar to items from IHSS scale to assess their presence and duration.

    Measured: From baseline to week 7

  6. Clinical Global Impression Scale for Change (CGI-C)

    CGI-C was used to measure, the change in excessive daytime sleepiness (EDS) compared to baseline. This scale if administrated by the same investigator and consists of a 7-grade scale as follows: "very much improved", "much improved", "minimally improved", "no change", "minimally worse," "much worse", "very much worse".

    Measured: From baseline to week 7

  7. Clinical Global Impression Scale for Severity (CGI-S)

    CGI-S is an observer-rated scale that measures illness severity by using a 7- grade scale ranging from ("normal, not at all ill") "borderline ill", "slightly ill", "moderately ill", "markedly ill", "severely ill", "among the most extremely ill patients".

    Measured: From baseline to week 7

  8. The EuroQol 5-Dimensional Descriptive System (EQ-5D-3L)

    EQ-5D-3L is a validated generic quality of life questionnaire that can be completed by the patient and/or caregiver and assesses 5 dimensions: mobility, washing and dressing, daily living activities, discomfort/pain, and anxiety. Each question has 3 response levels: no problem, some problems and important problems. The questionnaire includes also a visual analog scale in which the patient quantifies his or her perception of quality of life using a score ranging from the worst imaginable state of health (0) to the best imaginable state of health (100).

    Measured: From baseline to week 7

  9. Work Productivity and Activity Impairment- General Health (WPAI:GH)

    WPAI:GH is a well validated instrument to measure the effect of health conditions on work productivity and daily activities. The WPAI-GH consists of six questions: 1 = currently employed; 2 = hours missed due to health problems; 3 = hours missed other reasons; 4 = hours actually worked; 5 = degree health affected productivity while working (using a 0 to 10 Visual Analogue Scale (VAS)); 6 = degree health affected productivity in regular unpaid activities (VAS).

    Measured: From baseline to week 7

  10. Questionnaire on Functional Outcomes of Sleep

    FOSQ consists of 10 questions related to the effects of fatigue on daily activities. Each item in the FOSQ is rated on a 4 to 6-point scale, where patients provide their level of agreement of frequency of occurrence specific statements to their functioning.

    Measured: From baseline to week 7

  11. Logbook for compliance to monitor

    The patient logbook must be completed throughout the treatment to monitor compliance with treatment.

    Measured: From baseline to week 7

  12. Percentage of sleep stages

    % of time spent in stage 1 and 2 sleep stages and stage 3 during polysomnography

    Measured: From baseline to week 7

  13. Microarousal index

    Microarousal index is apneas + hypopneas per hour of sleep during polysomnography assessment. When the respiratory event index (apneas + hypopneas per hour of sleep) is between 5 and 15 per hour of sleep, SAS is considered mild, and between 15 and 30, moderate. Above 30, it is severe.

    Measured: From baseline to 7 weeks

  14. Total sleep time

    Total sleep time measured in minutes during polysomnography

    Measured: From baseline to 7 weeks

A Phase 2 study testing Solriamfetol in people with Idiopathic Hypersomnia, run by University Hospital, Montpellier at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 19 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Yves DAUVILLIERS, MD (+33467335219, y-dauvilliers@chu-montpellier.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Idiopathic hypersomnia severity scale (IHSS) score (time frame: From baseline to week 7). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
