Brief summary
The main objectives of this study are to determine the treatment preferences of children with narcolepsy type 1 between Extended-release sodium oxybate and Non-extended-release oxybates (Sodium oxybate or a medication with the combination of Calcium, magnesium, potassium, and sodium oxybates). The study will also assess the safety, convenience, and tolerability of Extended-release sodium oxybate. Additionally, the researchers aim to assess how well Extended-release sodium oxybate works in treating narcolepsy type 1.
Interventions
DRUGExtended-release sodium oxybate
Participants will take Extended-release sodium Oxybate (Lumryz) 4.5-9 g oral suspension in approximately ⅓ cup of water orally once a day before bedtime. Dosage of Lumryz will be the same as the equivalent total dose of the Non-Extended-release Oxybate (Xywav or Xyrem) that participants use before starting the study
DRUGNon-extended-release oxybates
Participants will take Non-Extended-release Oxybates (Xyrem oral solution or Xywav oral solution) 4.5-9 g orally per night (divided into two doses, once before bedtime and another dose 2-4 hours later) at the same dose of Xyrem or Xywav that participants use before starting the study will be continued to compare with Extended-release sodium Oxybate (Lumryz)

Inclusion criteria
1. Participants must be under the care of a doctor at the Stanford Sleep Clinic. 2. Participants must have a documented diagnosis of narcolepsy type 1 shown by sleepiness and either: a spinal fluid marker for narcolepsy (hypocretin-1) at a specific level, or a history of sudden loss of muscle control (cataplexy), or a particular genetic marker for narcolepsy, or a sleep study showing a specific sleep pattern for narcolepsy. 3. Parent(s), or guardian(s) have signed a consent form and the child must agree to participate. 4. Participants are on a stable dose of medications

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Participant preference for selecting the extended vs non-extended release oxybates | Baseline, up to 8-12 weeks through study completion | Participants will be asked at the end of the study whether participants prefer extended-release sodium oxybate vs sodium oxybate vs calcium, magnesium, potassium and sodium oxybates |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Epworth Sleepiness Scales for Children and Adolescents (ESS-CHAD) score | Baseline, up to 8-12 weeks through study completion | ESS-CHAD is a multi-item questionnaire which asks the participants to rate their chances of falling asleep during various normal daily activities. 4-point Likert scale will be used. The score ranges from 0-24. A higher score means higher chance of falling asleep. |
| Number of cataplexy attacks | Baseline, up to 8-12 weeks through study completion | The study team will ask the participants to report the number of cataplexy attacks as measured by Sleep and Symptoms diary when participants switch to the other intervention. |
| Change in Patient Global Impression of Change (PGIc) scale score | Baseline, up to 8-12 weeks through study completion | The PGIc is a 7-point scale. Participants will be asked to rate their narcolepsy impression since the end of the Stable-Dose Period. The scale is Very much better, Much better, A little better, No change, A little worse, Much worse, and Very much worse. |
