The trial will continue for up to 24 months or until marketing approval, whichever occurs sooner.
NCT00330291 ↗ Xyrem for Treatment Refractory Insomnia Due to PTSD Withdrawn State University of New York - Upstate Medical University Phase 2 2005-08-01 Xyrem (sodium oxybate) is an agent with the propensity to improve slow wave sleep and sleep efficiency. It is FDA approved to treat cataplexy (drop attacks) associated with narcolepsy (sleep attacks). It has been shown to be a safe and effective agent here where deep, restorative slow wave sleep improves and next day cataplexy attacks tend not to occur. Post Traumatic Stress Disorder (PTSD) is a psychiatric illness where a patient has witnessed or been involved in a traumatic event. After the event is over, nightmares, flashbacks, avoidance of people and places associated with trauma and hyperarousal occur which is incapacitating to the patient. One major part of PTSD hyperarousal is marked insomnia with multiple awakenings at night. This resultant poor sleep is compounded by use of SSRI serotonergic antianxiety agents (ie Zoloft(sertraline)) as first line therapy which tend to degrade slow wave, restorative sleep. Patients may respond to SSRI treatment but may fail to remit as they continue to have sleep problems. PTSD patients will often fail to respond to antihistamine (Desyrel (trazodone)) and benzodiazepine GABA hypnotic agents (Restoril(temazepam)) and continue with poor, interrupted sleep. It is possible that Xyrem's ability to remarkably improve slow wave sleep may greatly help treatment refractory insomnia due to PTSD. The author proposes an open-label study (no placebo) where 10 PTSD patients, who have failed usual PTSD treatments and have failed usual insomnia treatments in particular will be given Xyrem in addition to their current PTSD medication. The authors wish to determine if Xyrem is a safe treatment optionin this difficult-to-treat patient population.
NCT00345800 ↗ Exploratory Clinical Study to Evaluate Sodium Oxybate (Xyrem) on Potential Endocrine Changes Completed UCB Pharma SA Phase 4 2006-04-01 To monitor for endocrine changes in response to treatment of cataplexy with Xyrem, to focus on the hypothalamic pituitary axis and to confirm the safety of Xyrem on potential endocrine changes.

Sodium Oxybate: Clinical Trials, Market Analysis, and Projections

Introduction to Sodium Oxybate

Sodium oxybate, commonly known by the brand name Xyrem, is a medication specifically approved for the treatment of narcolepsy, particularly for managing excessive daytime sleepiness (EDS) and cataplexy. Here, we will delve into the recent clinical trials, market analysis, and future projections for this drug.

Clinical Trials Update

REST-ON Trial

The pivotal phase 3 REST-ON trial has been a significant milestone in the clinical development of sodium oxybate. This multicenter, randomized, double-blind, placebo-controlled trial (NCT02720744) evaluated the efficacy and safety of an extended-release, once-nightly formulation of sodium oxybate (ON-SXB), known as FT218 or LUMRYZ[1][4].

  • Participants and Dosage: The trial included patients aged 16 years and older with narcolepsy type 1 (NT1) and type 2 (NT2). Participants were randomized 1:1 to receive either ON-SXB or placebo, with dosages titrated from 4.5 g to 9 g over a 13-week period.
  • Endpoints: The trial assessed three coprimary endpoints: mean sleep latency on the Maintenance of Wakefulness Test (MWT), Clinical Global Impression-Improvement (CGI-I) rating, and the number of weekly cataplexy attacks. Secondary endpoints included changes in the Epworth Sleepiness Scale (ESS)[1][4].
  • Results: The trial demonstrated statistically significant improvements in all coprimary and secondary endpoints compared to placebo. For example, at the 9 g dose, ON-SXB showed a significant increase in mean sleep latency and a reduction in cataplexy attacks and daytime sleepiness[1][4].

Safety Profile

The safety profile of ON-SXB was consistent with that of traditional sodium oxybate. Common adverse reactions included nausea, vomiting, headache, dizziness, and enuresis, which generally subsided over time[1][4].
