Study Stopped
A safety signal has emerged in Phase 2 studies of TAK-994. As an immediate precautionary measure, Takeda has suspended dosing of patients and has decided to stop Phase 2 studies early.
A Study of TAK-994 in Adults With Type 1 and Type 2 Narcolepsy
A Randomized, Double-Blind, Placebo-Controlled, Multiple Rising Oral Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of TAK-994 in Patients With Narcolepsy With or Without Cataplexy (Narcolepsy Type 1 or Narcolepsy Type 2)

Brief Summary
The main aims of the study are:
- To check for side effects from TAK-994 and check what dose of TAK-994 participants can tolerate.
- To check what dose range provides adequate relief of narcolepsy symptoms.
- To check how much TAK-994 stays in the blood of participants, over time. The study will have 4 parts. Participants can only join 1 of the parts. A. Participants with type 1 narcolepsy will take either TAK-994 or placebo tablets for 28 days. A placebo looks just like TAK-994 but will not have any medicine in it. B. Participants with type 1 narcolepsy will take 1 of 3 doses of TAK-994 or placebo tablets for 56 days. C. Participants with type 1 narcolepsy in China only will take TAK-994 or placebo tablets for 56 days. D. Participants with type 2 narcolepsy will take either TAK-994 or placebo tablets for 28 days.

Outcome Measures
Primary Outcomes (5)
Part A: Number of Participants Who Experience at Least One Treatment Emergent Adverse Event (TEAE) During the Study
An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A TEAE is defined as an AE with an onset that occurs after receiving study drug.

Parts B and C: Change From Baseline in Average Sleep Latency as Assessed by the Maintenance of Wakefulness Test (MWT)
MWT: validated, objective measure that evaluates person's ability to remain awake under soporific conditions for defined period. During each MWT session (1 session=40 minutes), participants were instructed to sit quietly and remain awake for as long as possible. Sleep latency in each session was recorded on electroencephalography (EEG). If no sleep had been observed according to these rules, then latency= 40 minutes. Mixed-effect model for repeated measures (MMRM) was used for analysis. Due to early termination of the study, no post-baseline efficacy data for this outcome measure was collected and analyzed for participants in Part C: TAK-994 180 mg.

Interventions
Eligibility Criteria
You may qualify if:
- Has a diagnosis of narcolepsy type 1 (NT1) (Parts A-C) or NT2 (Part D) by polysomnography (PSG)/ multiple sleep latency test (MSLT) performed within the past 10 years meeting the minimal acceptable criteria for the proper performance of the PSG/MSLT as outlined by the International Classification of Sleep Disorders, 3rd edition criteria.
- The participant's Epworth Sleepiness Scale (ESS) score must be greater than or equal to (\>=) 10 at Day -1.
- Must be willing to discontinue all medications used for the treatment of NT1/NT2.
- The human leukocyte antigen (HLA) genotype: Part A: should test positive for human leukocyte antigen (HLADQB1)\* 06:02 (PARTs A-C)- (positive results for either homozygous or heterozygous alleles will be considered "positive" and acceptable). However, if the HLA test is negative (i.e. negative for the heterozygous allele) and the PI feels strongly that the participant has narcolepsy with cataplexy (NT1) then a discussion should be initiated between the PI and the sponsor or designee about the advisability of doing a spinal tap to determine the participant's cerebrospinal fluid (CSF) orexin-1 (OX-1) level. If the CSF result shows the orexin 1 (OX-1) concentration is either less than or equal to\<110 pg/mL, or less than one-third of mean values obtained in normal participants with the same standardized assay, then the diagnosis of NT1 is established allowing the participant to be enrolled and randomized, If the CSF OX-1 concentration is \>110 pg/mL then the participant will not be allowed to continue in the study .
- For Parts A, B, and C, during the screening period, participant, must have \>=4 partial or complete episodes of cataplexy/week (WCR), and \>=4 partial or complete episodes of cataplexy/week during the screening period when off of anticataplexy medications, averaged over 2 weeks (14 consecutive days) minimum. WCR recording taken during following period will be considered for study eligibility: after the participant has stopped taking anticataplexy medications for at least 7 days (minimum 7-day washout) and study Day -2.
You may not qualify if:
- Has a risk of suicide according to endorsement of Item 4 or 5 of the screening/baseline visit Columbia suicide severity rating scale (C-SSRS) or has made a suicide attempt in the previous 12 months.
- Is an excessive (\>600 mg/day) caffeine user 1 week before to the study screening.
- Has a usual bedtime later than 2400 (12:00 AM, midnight) or an occupation requiring nighttime shift work or variable shift work within the past 6 months or travel within more than 3 time zones, within 14 days before Study Day -2.
- Has a nicotine dependence that is likely to have an effect on sleep (e.g., a participant who routinely awakens at night to smoke) and/or an unwillingness to discontinue all smoking and nicotine use during the confinement portions of the study. Participants undergoing optional CSF collection.
- Has a local infection at the puncture site.
- Has developed signs of lumbar radiculopathy, including lower extremity pain and paresthesia.
- Has any known focal neurological deficit that might suggest an increase in intracranial pressure.
