The total participation duration extends up to approximately 100 weeks, with safety, tolerability, and treatment effects closely tracked throughout this period.

Researchers are conducting a Phase 3, multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of HBS-301 in adults aged 18 years and older with narcolepsy. The study focuses on treating excessive daytime sleepiness EDS, cataplexy, sleepinesswakefulness, and fatigue in participants diagnosed with narcolepsy. Approximately 258 participants will be included in this trial. Participants will be randomly assigned to receive either HBS-301 tablets or matching placebo tablets once daily in the morning upon waking. The study includes a ScreeningBaseline period lasting up to 28 days, followed by an 8-week Double-blind Treatment period. After this, participants may choose to enter a 1-year Open-label Extension period where they will receive HBS-301. Finally, a 30-day safety follow-up will monitor participants after treatment ends. Throughout the study, participants will undergo various assessments including evaluations of daytime sleepiness using the Epworth Sleepiness Scale, cataplexy frequency, wakefulness through the Maintenance of Wakefulness Test, fatigue levels, cognitive complaints, quality of life, and work productivity. Safety will be monitored by tracking adverse events and pharmacokinetic measurements. The total study participation may last up to approximately 16 months including all phases.

Researchers are evaluating the safety, tolerability, and effects of ORX750 in adults with Narcolepsy Type 1 NT1, Narcolepsy Type 2 NT2, and Idiopathic Hypersomnia IH. These rare conditions cause excessive daytime sleepiness and affect daily activities such as school, work, and driving. The study aims to understand how ORX750, which mimics the brain protein orexin that helps maintain wakefulness, impacts sleepiness and other symptoms in these conditions. Participants will receive either ORX750 capsules or matching placebo capsules in a randomized, double-blind setup. The study assesses multiple groups those with NT1, NT2, and IH. The treatment and monitoring will occur over a period of up to 35 days, including evaluation of plasma drug levels and sleepiness measures. During the study, participants will undergo safety assessments including monitoring for adverse events, laboratory tests, vital signs, ECGs, and suicidal ideation screening up to day 35. Researchers will also measure sleepiness using the Maintenance of Wakefulness Test and the Epworth Sleepiness Scale. The total study duration for each participant is about five weeks, with careful observation of how the body processes ORX750 and its effects on daytime alertness.

Idiopathic Hypersomnia IH is a condition where adults feel extremely sleepy during the day, especially in the morning, even after sleeping a lot at night. This condition can cause difficulty waking up, trouble focusing, and symptoms like dizziness. Researchers are studying TAK-360, a drug that acts like orexin, a brain chemical that helps keep people awake. The study aims to understand how safe and tolerable TAK-360 is for adults with IH and to find the right dose to help with wakefulness. Participants in the study will be randomly assigned to receive either TAK-360 tablets or placebo tablets that look the same but contain no active medicine. Both treatments will be taken orally for 4 weeks. The study uses a double-blind design, meaning neither participants nor researchers know who receives the drug or placebo, to fairly evaluate the effects of TAK-360. During the study, participants will be monitored for safety and side effects up to 8 weeks. Researchers will measure changes in daytime sleepiness using the Epworth Sleepiness Scale and symptoms using the Idiopathic Hypersomnia Severity Scale at the start and after 4 weeks. The trial will also track any treatment-emergent adverse events. The total participation time may include screening, treatment, and follow-up assessments over several weeks.

Narcolepsy Type 2 NT2 is a lifelong condition causing excessive daytime sleepiness, difficulty staying awake, and problems with concentration and memory, impacting daily life activities. Researchers are evaluating TAK-360, a drug that acts like orexin, a brain chemical that promotes wakefulness, to understand its safety, tolerability, and ability to help adults with NT2 stay awake. This is a Phase 2, randomized, double-blind, placebo-controlled study to find the right dosage of TAK-360. Participants will be randomly assigned to receive either TAK-360 tablets or matching placebo tablets orally for 4 weeks. TAK-360 is being studied to assess its effects compared to placebo. The study uses a parallel design and includes a 4-week treatment period where participants take the assigned tablets daily. During the study, participants will be monitored for treatment-emergent adverse events for up to 15 weeks. Researchers will assess wakefulness using tools like the Epworth Sleepiness Scale and the Maintenance of Wakefulness Test at baseline and after 4 weeks of treatment. Safety, tolerability, and efficacy data will be collected throughout the study, which runs until November 2026.

Researchers are evaluating the safety and tolerability of TAK-861 in people with narcolepsy type 1 NT1. This study focuses on participants who have already been exposed to TAK-861 doses in previous clinical trials. The goal is to monitor how TAK-861 affects symptoms such as excessive daytime sleepiness and cataplexy episodes over a long period. All participants in this trial will receive TAK-861 tablets. Those who previously received a placebo will be randomly assigned to one of the TAK-861 dose groups. The study is a long-term extension conducted worldwide and is expected to last approximately five years or until the product is approved or the study is stopped. Participants may switch doses as needed and will attend multiple clinic visits, some of which can be done at home. Throughout the trial, participants will be regularly assessed for safety by tracking any treatment-emergent adverse events. Researchers will also measure changes in sleep latency, sleepiness scores, and cataplexy rates compared to baseline data from earlier trials. Follow-up assessments will take place four weeks after the final dose to monitor ongoing effects and ensure participant safety.

Researchers are evaluating the optimal doses of the drug E2086 compared to placebo in adults with narcolepsy, a condition characterized by excessive daytime sleepiness EDS. The study focuses on reducing EDS as measured by the Mean Sleep Latency MSL using the first four maintenance of wakefulness tests MWTs. This Phase 2 trial includes participants diagnosed with either narcolepsy type 1 NT1 or type 2 NT2 within the last 10 years. Participants will be randomly assigned to receive either E2086 or a matching placebo tablet taken orally once daily for four weeks at low, middle, and high doses. Each dosing period is separated by a washout period of at least seven days, with a total treatment duration of approximately 14 weeks. This design allows comparison of the effects of different doses of E2086 on narcolepsy symptoms. During the study, participants will undergo assessments to measure changes in sleep latency, cataplexy episodes, and sleepiness scales. Additional safety evaluations include monitoring for adverse events, laboratory tests, vital signs, ECG parameters, and suicidality assessments. Blood samples will be collected to analyze drug concentration levels. The study involves regular monitoring up to Day 113 and aims to assess both efficacy and safety over the course of treatment and follow-up.

This research aims to evaluate the long-term safety and explore the efficacy of astegolimab in adults aged 40 to 90 years with chronic obstructive pulmonary disease COPD. It focuses on participants who have completed a 52-week placebo-controlled treatment period in previous studies GB43311 or GB44332. The study is a phase 3, open-label extension to gather extended safety information on this drug in COPD patients. Participants from the parent studies who qualify will receive subcutaneous injections of astegolimab every two weeks throughout the study until it ends. This open-label extension allows all participants to receive the active drug without placebo comparison. The study continues treatment beyond the initial 52-week period to monitor long-term effects. During the study, participants will be monitored for adverse events up to 12 weeks after their last dose of astegolimab. Researchers will collect safety data to understand the incidence of any side effects. The study involves regular assessments and follow-ups to ensure participant well-being, with the total duration lasting until July 2034.
