研究概览
简要总结
The purpose of this study is to determine whether portable devices can provide measurements at home similar to those taken in the clinic, in particular in participant with NT1, and to investigate night-to-night changes in sleep patterns using these devices at home. This study may enable future at-home studies and ultimately lead to a decreased burden on the people who need these measurements.
详细描述
This is a non-drug study including participants with NT1 and healthy participants using devices designed for at-home assessments. The study will assess whether a portable EEG device provides an EEG signal comparable to inpatient nPSG. The frequency and characteristics of wake and sleep patterns and transitions over multiple nights will also be characterized. Participants with NT1 who will complete the study TAK-994-1501 (NCT04096560) will be eligible to enter the current study following the appropriate washout period (60 days).
The study will enroll approximately 32 participants (16 participants with NT1 and 16 healthy participants). Participants will be enrolled in the 2 groups:
- NT1 Participants
- Healthy Participants
This multi-center trial will be conducted in the United States. The overall time to participate in this study is approximately 8 days. The follow-up visit will occur on Day 10 and during this debrief, participants will answer a questionnaire on user experience (device comfort) for the wearable devices.

入选标准
- •Has access to at-home Wi-Fi and can add an internet-ready device with assistance.
- •Body mass index (BMI) between greater than equal to (>=) 18.0 and less than or equal to (<=) 40.0 kilogram per square meter (kg/m^2) at the screening visit.
- •Must have regular sleep-wake habits (example, routinely spending 6.5 to 8.5 hours sleeping nightly, not oversleeping by more than 2 hours on weekends, that is, total sleep not more than approximately 10.5 hours) as determined by investigator interviews and confirmed in accelerometry/actigraphy records obtained between screening and first visit (measured using a minimum of 10 day/night consecutive periods) and who regularly fall asleep between 9:30 PM and 12:00 AM (healthy participants only).
- •Must not require use of sleep aids or must be willing to discontinue use of sleep aids for the duration of the study.
- •Has completed the TAK-994-1501 study, the participant is eligible to enter the current study following the appropriate washout period (60 days).
- •Participants With NT1 Only:
- •With NT1 who is drug-naïve may also be enrolled.
- •With NT1 must present with subjective sleep complaint.
- •With NT1 must have a diagnosis of NT1, as defined by the International Classification of Sleep Disorders, 3rd edition (ICSD-3) criteria.
排除标准
- •Has a current diagnosis of cancer except for squamous or basal cell skin cancer.
- •Has a nicotine or marijuana dependence that is likely to have an effect on sleep (example, a participant who routinely awakens at night to smoke) and/or an unwillingness to discontinue all smoking and nicotine use during the confinement portions of the study.
- •Cannot maintain stable sleep environment at home, for example, due to young children not yet sleeping through the night or partners with disrupted sleep (example, shift workers).
- •Undergoing current treatment for hepatitis B with interferon.
- •Has a risk of suicide according to endorsement of Item 4 or 5 of the screening visit Columbia Suicide Severity Rating Scale (C-SSRS) or has made a suicide attempt in the previous 6 months.
- •Has medical condition, such as past or current epilepsy, seizure, head injury/trauma, medically significant unstable cardiovascular, pulmonary, hepatic, renal, or gastrointestinal disease, that interferes with a normal sleep pattern or would preclude enrollment in the view of the investigator.
- •Has a lifetime history of major psychiatric disorder, such as bipolar disorder or schizophrenia.
- •As of the screening visit and throughout the study, the participant should not be a chronic caffeine user, as defined by an excessive (greater than [>] 600 milligram [mg]/day) caffeine intake per day.
- •Has a medical disorder (other than narcolepsy), associated with excessive daytime sleepiness. This includes clinically significant obstructive sleep apnea or other sleep disturbances that has a significant impact on daytime sleepiness, confirmed by past PSG data (example, apnea hypopnea index >=10, periodic limb movement disorder index in sleep >=15) or a periodic limb movement disorder arousal index of >=10, or as evaluated on interview at the screening visit. Because nPSG data is obtained on Day 1, participants may be removed from study if they meet the above exclusion at the discretion of the principal investigator. Participants removed under this criterion will be replaced.
- •At the time of screening the participant is being treated with nasal or oro-nasal positive airway pressure for any reason.
- •Is currently being prescribed sodium oxybate or has been off of sodium oxybate for less than 4 weeks.
- •Is using varenicline (Chantix).
结局指标
主要结局
Sleep State Scoring From nPSG and Portable EEG Device
时间窗: up to 2 Nights
The concordance between EEG signals obtained from the portable EEG device with nPSG over 2 inpatient night stays will be assessed using data obtained during the inpatient setting from nPSG and a portable EEG device. Scoring of sleep stages occur in 30-seconds epoch based on American Academy of Sleep Medicine (AASM) scoring rules. The output from the nPSG and the portable EEG device will be hand scored for each participant, with the rater assigning 1 of 5 sleep/wake stages to each 30 second epoch 3 stages of non-REM (NREM) sleep (N1, N2, N3), rapid eye movement (REM), and wakefulness (W). The nPSG is a standardized procedure used to assess various sleep parameters, including sleep latency and sleep architecture. nPSG will be used to as the comparator to the portable EEG device.
Stage Shift Index (SSI) as Measured by Standard nPSG and EEG Device on Night 2
时间窗: Night 2
SSI will be measured by standard nPSG and portable EEG device on Night 2 in the clinic. SSI will be calculated as the number of transitions between any wake or sleep stage divided by hours of total sleep time. The summary of the frequency of different stages of sleep transitions can be represented by SSI, which can be used to differentiate healthy participant from those with sleep pathology. The correlation between the SSI as measured by the portable EEG device and by the nPSG will be analyzed for participants with NT1 and healthy controls. The nPSG is a standardized procedure used to assess various sleep parameters, including sleep latency and sleep architecture. nPSG will be used as the comparator to the portable EEG device.
次要结局
- Number of Microsleeps and State Transitions During the Maintenance of Wakefulness Tests (MWTs)(Day 2)
- SSI as Measured by Standard nPSG and EEG Device During the Period at Home(Nights 3-7)
