RAISE UP STUDY for Adults with Narcolepsy Type 1 (NT1)
RECRUITMENT COMPLETED as of August 2023 for adults (18 and over) with Narcolepsy Type 1: CLICK HERE.
If you have narcolepsy with cataplexy (also known as narcolepsy type 1), you may be eligible to participate in research. The purpose of the RaiseUp Study is to evaluate the safety and effectiveness of an investigational study drug in the treatment of adults who have narcolepsy type 1 (NT1). This study may help researchers understand how the body processes the investigational study drug and how it may affect excessive daytime sleepiness (EDS).
Who Can Participate?
Eligible participants must:
- Be 18 to 70 years of age.
- Have received an NT1 diagnosis within the past 10 years or are experiencing NT1 symptoms (characterized by cataplexy, or the sudden loss of muscle control and muscle weakness due to strong emotions or actions, like anger or laughter, while remaining conscious).
- Be willing to stop any current NT1 treatment.
For more information about the RaiseUp Study or to take the prescreening questionnaire and see if you may qualify, talk to your doctor and visit the RaiseUp Study website.

XW Labs’ Phase 1 Study in Australia for Treatment of Narcolepsy With XW10172
Study completed May 2019. See XW Labs Initiates First-in-Human Phase I Study for Novel Narcolepsy Treatment. More information at the Australian New Zealand Clinical Trials Registry.
May 2021: XWPharma Announces Abstract for XW10172 Accepted for Presentation at the Associated Professional Sleep Societies SLEEP 2021 Annual Meeting.
"XW10172 is a conjugate of the GABAB receptor agonist, oxybate, that is in development as a modified release formulation intended to provide the desired tolerability and efficacy based on once-nightly dosing. The drug and formulation are designed to deliver oxybate without the sodium content of other products that is associated with increased cardiovascular health risk and monitoring requirements. The company plans to develop XW10172 for treatment of sleep disorders associated with neurodegenerative diseases, starting with excessive daytime sleepiness in patients with Parkinson’s disease and cataplexy and excessive daytime sleepiness in patients with narcolepsy."
Safety and Efficacy of THN102 on Sleepiness in Narcoleptic Patients
RECRUITMENT COMPLETE as of Fall 2018: see clinicaltrials.gov. Theranexus' THN102 is a combination of modafinil and flecanide combo. Flecainide is "an antiarrhythmic agent used in this instance at very low dosages and for its modulating effects on the glial connexins.”
Results:
- July 2018: Theranexus presents data on stimulating effect of new drug candidate. THN 102 is currently in Phase II clinical evaluation in narcolepsy and a Phase II trial in Parkinson's is also planned.
- February 2019: Theranexus Announces Preliminary Results of Phase II Trial of Thn102 on Narcolepsy Patients. "THN102's safety and tolerability profile has been deemed very satisfactory. However, the results do not indicate any difference in efficacy between THN102 (combination of modafinil and flecainide) and modafinil alone with respect to the trial’s primary endpoint (Epworth Sleepiness Scale). An over-representation of poorly responding narcoleptic patients may account for THN102's lack of difference in efficacy from the standard of care drug."
- September 2019: Efficacy of THN102 on vigilance and cognition during 40-hour total sleep deprivation in healthy subjects: Glial connexins as a therapeutic target. "THN102 seems more efficient than modafinil on vigilance, working memory and executive functions, opening new perspectives in management of hypersomnolence disorders."
- September 2020: THN102 Improves Excessive Daytime Sleepiness in Parkinson Disease.
Umecrine Cognition’s Phase IIa Study of GR3027 in Patients With IH
RECRUITING COMPLETE as of Fall 2018. GR3027 was originally developed with the intention to reverse the hypersomnolence and impairments in cognition that occur in the clinical setting of liver failure – aka, hepatic encephalopathy. In October of 2017, Umecrine Cognition expanded their study of GR3027 to IH (see Umecrine Cognition Expands Study of New Medicine GR3027 to IH).
In January, 2019, Umecrine Cognition announced their overall results from their Phase 2a Study. The primary study objectives were met in regard to safety and pharmacokinetics and also showed preliminary evidence of clinical efficacy. CLICK HERE to find out more about these results.
As of November, 2020, although GR3027 continues to be tested for liver failure, there has been no further development for IH. Read more HERE.
Survey Study on Autonomic Impairment in Adults With Idiopathic Hypersomnia (IH)
RECRUITING COMPLETE as of September 2018. In 2018, HF promoted this Stanford University-based survey study of autonomic impairment in adults with IH. Autonomic dysfunction includes symptoms like dizziness, bowel or bladder trouble, and temperature and heart rate dysregulation.
Results:
- May 2019 Autonomic Symptom Burden in Idiopathic Hypersomnia: abstract published as part of the annual meeting of the AAN (American Academy of Neurology). The researchers found that people with IH reported extremely high levels of autonomic dysfunction, on par with other conditions of severe autonomic failure, like MSA (multiple system atrophy) and diabetes. “Symptoms of ANS impairment, sleepiness, and fatigue are more severe in individuals with IH compared to controls. Moreover, ANS symptom burden correlates moderately with higher levels of sleepiness and fatigue.” The researchers also hope to complete follow-up studies and provide a more detailed exploration of the potential mechanisms involved. "Future analysis will focus on COMPASS [composite autonomic symptom score-31] subscores and objective autonomic testing to help identify symptomatic domains, with the goal of more focused therapeutic targets for patients with IH."
- May 2020 Frequency and severity of autonomic symptoms in idiopathic hypersomnia: publication in the Journal of Clinical Sleep Medicine.

Health and Well-Being in Those With and Without a Disorder of Daytime Sleepiness—A Research Survey From Australia
In 2015, Victoria University in Melbourne, Australia, commenced a study about the general health and well-being of people within three groups. The first group was those people with both narcolepsy and cataplexy. (Cataplexy is a sudden loss of muscle tone, often triggered by emotional arousal.) The second group was people with either narcolepsy-without-cataplexy or idiopathic hypersomnia. The third group had no disorders of excessive daytime sleepiness. This project was part of a PhD program by Samantha Gauci (under the supervision of Prof. Dorothy Bruck and Dr. Warwick Hosking). One question in the study was whether the presence of cataplexy in narcolepsy was associated with a different level of general health and well-being (and some symptoms such as pain and migraines).

The TONES Study (Jazz Pharmaceuticals’ JZP-110/Solriamfetol)
In 2015, doctors began conducting the TONES medical research study of an investigational product (JZP-110) designed to treat sleepiness and to help adults stay awake. The researchers wanted to evaluate the product’s effectiveness against excessive sleepiness when taken once a day for 12 weeks. Participants had to have been diagnosed with narcolepsy and sleeping at least 6 hours a night. For further info, CLICK HERE.
Results of related research into JZP-110:
- January 2019: A Randomized Study of Solriamfetol for Excessive Sleepiness in Narcolepsy. This phase 3 study evaluated the safety and efficacy of solriamfetol in narcolepsy.
- March 2019: Solriamfetol was approved by the U.S. FDA for the treatment of sleepiness caused by narcolepsy and obstructive sleep apnea.
