Vibrance study 1&2

Purpose: We are looking for participants with Narcolepsy (Type 1 or Type 2) to evaluate safety and efficacy of ALKS 2680 in NT1 and NT2. ALKS 2680 is a selective orexin-2 receptor agonist that aims to restore orexin signaling, and, thereby promote wakefulness and ameliorate cataplexy in patients with NT1/NT2.

Inclusion:

NT1 or NT2

Study Requirements:

F2-week medication washout
2 overnight visits, up to 9 in-clinic visits, up to 12 virtual visits
Questionnaires, blood samples, actigraphy monitoring, sleep/cataplexy diaries

Compensation:

up to $2250 - $3350

Impact of Low Sodium Oxybate on Total Sleep Time in Patients with Idiopathic Hypersomnia

Purpose: Stanford University and Mayo Clinic have partnered to evaluate the efficacy of low sodium oxybate (Xywav) on total sleep time in patients with idiopathic hypersomnia. The comprehensive assessments will yield detailed information about how low sodium oxybate affects sleep, breathing, and other physiological metrics, ultimately enhancing understanding of idiopathic hypersomnia.

Inclusion:

IH, recommended low sodium oxybate, 18-65 years old, BMI 18-35 kg/m², sleep duration ≥ 9 hours

Exclusion:

Various medical/psychiatric conditions, shift workers.

Study Requirements:

3-5 months, 6-7 visits at Redwood City Sleep Clinic.
2 24-hour in-lab sleep study, actigraphy monitoring, blood draw
participants will receive an active dose of XYWAV at no cost.
