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.

Outcome Measures
Primary Outcomes (1)
Participant preference for selecting the extended vs non-extended release oxybates
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
Baseline, up to 8-12 weeks through study completion
Secondary Outcomes (3)
Change in Epworth Sleepiness Scales for Children and Adolescents (ESS-CHAD) score
Baseline, up to 8-12 weeks through study completion
Number of cataplexy attacks
Baseline, up to 8-12 weeks through study completion
Change in Patient Global Impression of Change (PGIc) scale score
Baseline, up to 8-12 weeks through study completion
Study Arms (2)
Extended-release sodium oxybate
EXPERIMENTALParticipants in this arm will take extended-release sodium oxybate
Non-extended-release oxybates
ACTIVE COMPARATORParticipants in this arm will take non-extended-release sodium oxybate
Interventions
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
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)

- Parent(s), or guardian(s) have signed a consent form and the child must agree to participate.
- Participants are on a stable dose of medications
You may not qualify if:
- Participants who have any of the following conditions will not be included in the study
