Inclusion criteria
Inclusion criteria: Healthy adult participants and Healthy elderly participants: - Participant weighs at least 50 kg (Healthy adults participants) / 40 kg (Healthy elderly participants) and has a body mass index (BMI) from 18.5 to 30 kg/m^2, inclusive at Screening. Narcolepsy patients: - Patient weighs at least 40 kg inclusive at Screening. - A diagnosis of narcolepsy Type 1, as defined by the International Classification of Sleep Disorders, Third Edition (ICSD-3). - A patient who is positive for HLA-DQB106:02 - At Day -1, Epworth sleepiness scale (ESS) score >=10 - Blood pressure <140 systolic and < 90 diastolic. The patient may have a history of hypertension and be on antihypertensive medication treatment as long as the BP meets these criteria.

HV (only Cohort 4): - Participant has had CSF collection performed within 14 days prior to Check-in (Day -1). Narcolepsy patients: - Medical disorder associated with excessive sleepiness other than narcolepsy (including sleep apnea syndrome). - Excessive caffeine (>400mg/day) use one week prior to study.

| efficacy Part 2:Average Sleep Latency in Maintenance of Wakefulness Test (MWT) The MWT is a validated objective measure that evaluates a person's ability to remain awake under soporific conditions for a defined period of time. This tendency to fall asleep is measured via electroencephalography-derived sleep latency. Sleep onset is defined as the first epoch of greater than 15 seconds of cumulative sleep in a 30-second epoch. Trials were ended after 40 minutes if no sleep occurs, or after unequivocal sleep, defined as 3 consecutive epochs of stage 1 sleep, or 1 epoch of any other stage of sleep. If no sleep has been observed according to these rules, then the latency is defined as 40 minutes. MWT sleep latency ranges from 0 to 40 minutes, with higher scores indicating greater ability to stay awake.. Time Frame: Days 1 and 3 up to 8 hours following the start of infusion | — |
