The most recent phase II clinical trial examining TAK-925 for people with idiopathic hypersomnia completed enrollment in 2020. Studying Idiopathic Hypersomnia: Takeda is also studying how orexin agonists might work to increase wakefulness in people with idiopathic hypersomnia. Phase II clinical trials are currently underway for people with type 1 narcolepsy with cataplexy and type 2 narcolepsy without cataplexy. TAK-994Ĭlinical Trial Opportunity: TAK-994 is an oral dose formulation OX2R agonist. Over the past 20 years, a few approaches have been explored, but promising research started coming out of Japan a few years ago from Takeda Pharmaceuticals. However, finding treatments able to cross the blood-brain barrier and mimic the function of orexin has been scientifically challenging. Since 1999, we’ve known that type 1 narcolepsy with cataplexy is caused by a selective loss of neurons producing the neuropeptide orexin (or hypocretin), which plays a central role in maintaining wakefulness. Most recently, in December 2020, Avadel announced the submission of its New Drug Application (NDA) to the FDA.Ĭlinical Research Opportunity: An open label study is currently evaluating the long-term safety and tolerability of FT218 and the ability to switch from twice-nightly sodium oxybate to once-nightly FT218. Under FDA Review: Since my last update, the FT218 Phase III clinical trial was completed and Avadel reported positive topline data in April 2020. This is being studied for the treatment of excessive daytime sleepiness (EDS) and cataplexy in people living with narcolepsy. FT-218īackground: FT218 is a once-nightly formulation of sodium oxybate using Avadel Pharmaceuticals’ proprietary Micropump® technology to provide an extended-release of the drug. This comes soon after Jazz Pharmaceuticals also announced here in 2018 that the FDA approved X yrem (sodium oxybate) to treat cataplexy and excessive daytime sleepiness (EDS) in children and adolescents with narcolepsy 7 years of age and older. Pediatric Indication: It is exciting that Xywav was FDA-approved for children ages 7 years and up. It is an oral solution that is administered at night in two doses.įDA Approval: In July 2020, Jazz Pharmaceuticals announced that the FDA approved the Xywav oral solution for the treatment of cataplexy or excessive daytime sleepiness in people with narcolepsy who are 7 years of age and older. Xywav is now FDA-approved and available on the market. Nighttime Medicationsīackground: Xywav is a low-sodium alternative to Xyrem, with 92 percent less sodium per nightly dose. I am not familiar with the trial sponsor, Suven Life Sciences, but look forward to learning more about their efforts. SUVN-G3031Ĭlinical Trial Opportunity: SUVN-G3031 is a novel histamine H3 receptor inverse agonist. 2020, Harmony Biosciences announced that the first patient enrolled in a Phase II trial evaluating the safety and efficacy of pitolisant for the treatment of excessive daytime sleepiness (EDS) and other key symptoms in people with Prader-Willi Syndrome (PWS). Learn more.įurther Clinical Research for Prader-Willi Syndrome: As of Dec. 2020, pitolisant/Wakix was also FDA-approved for the indication of cataplexy as well. Subsequently, in the U.S., Harmony Biosciences LLC announced FDA approval for pitolisant/Wakix for the indication of excessive daytime sleepiness in narcolepsy in 2019 and the treatment went onto the U.S. This article offers some ideas about how the treatment may work.įDA Approval: In 2016, pitolisant (trade name: Wakix) was approved and on the market in Europe. Histamine-directed medications Pitolisant/Wakixīackground: Pitolisant is a histamine H3 receptor inverse agonist that activates histamine neurons, which is an exciting advancement because pitolisant works via a different mechanism than other treatment options for narcolepsy. As of July 2019, Sunosi became commercially available in the United States. Wake-promoting or stimulant medications Solriamfetol/Sunosiīackground: Solriamfetol (trade name Sunosi) is a wake-promoting agent, a dual-action dopamine and nonrepinephrine reuptake inhibitor to treat excessive daytime sleepiness in people with narcolepsy and obstructive sleep apnea.įDA Approval: In March 2019, Jazz Pharmaceuticals announced here that the FDA approved solriamfetol/Sunosi for the treatment of excessive sleepiness in adults with narcolepsy or obstructive sleep apnea. Wake-promoting or stimulant medications.There are new and upcoming narcolepsy treatment options in these categories: I shared progress updates in 20, and am excited to publish a new update today! Drug development in the narcolepsy space has gained incredible momentum the past few years.
