Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 65 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • 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.

Who cannot join

  • 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 history of cancer (except carcinoma in situ that has been resolved without further treatment or basal cell skin cancer); past or current epilepsy, seizure; a lifetime history of major psychiatric disorder other than depression or anxiety; a clinically significant history of head injury or head trauma; a history of cerebral ischemia, transient ischemic attack, intracranial aneurysm, or arteriovenous malformation; known coronary artery disease, a history of myocardial infarction, angina, cardiac rhythm abnormality, or heart failure; or current or recent (within 6 months) gastrointestinal disease expected to influence the absorption of drugs. Any history of Roux-en-Y gastric bypass is considered exclusionary and any other surgical intervention that may influence the absorption of drugs should be discussed and approved by the sponsor or designee before enrolling the participants.
  • Has a medical disorder, other than narcolepsy, associated with EDS. This includes clinically significant moderate to severe obstructive sleep apnea and/or with or without treatment with mandibular advanced device hypoglossal nerve stimulation and/or positive airway pressure (PAP) therapy) and/or restless legs syndrome (RLS)/periodic limb movement disorder that has a significant impact on daytime sleepiness. This is evidenced by a clinical history of sleep apnea syndrome (loud snoring with observed respiratory pauses in the absence of nPSG) and/or RLS causing historical sleep onset/maintenance insomnia with resultant insufficient sleep. Or any as evaluated during the clinical interview at screening. pPast PSG data demonstrating any of the following sleep disturbances: apnea Hypopnea Index ≥15 or apnea index ≥10, an oxygen saturation of <80 for >10 seconds, periodic leg movement arousal index of ≥15/h) or as evaluated on interview at the time of screening. Asshould be considered exclusionary unless, based on a clinical evaluation by the investigator, a meaningful change in clinical status has occurred that would impact the results. Because nPSG data is obtained on Day -2, subjects may fail screening if criteria are not meet on the Day -2 nPSG.
  • 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.

About this study

Official title: 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)

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.

  1. 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.
  2. Participants with type 1 narcolepsy will take 1 of 3 doses of TAK-994 or placebo tablets for 56 days.
  3. Participants with type 1 narcolepsy in China only will take TAK-994 or placebo tablets for 56 days.
  4. Participants with type 2 narcolepsy will take either TAK-994 or placebo tablets for 28 days.
Read the detailed description

The drug being tested in this study is called TAK-994. TAK-994 is being tested in participants with NT1 and NT2.

The study will enroll up to approximately 202 participants. The study has 4 Parts: Parts A, B, C (China only) and D. Part A - Part A has 2 cohorts [Cohorts (A1a and A1b) A2] In both of these Cohorts, participants will be randomly assigned (by chance, like flipping a coin) in a 2:1 ratio to receive TAK-994 or placebo up to 28 days:

  • Part B: In Part B, participants will be randomized in 1:1:1:1 ratio in four parallel arms to receive TAK-994 Dose 1, 2 or 3 or placebo for 56 days. Depending upon their eligibility participants completing Part B of the study treatment will be enrolled to participate in an Extension study.
  • Part C: In Part C, participants only from China will be enrolled and randomized in a 2:1 ratio to receive TAK-994 and placebo for 56 days.
  • Part D: Participants will be included in two cohorts [Cohorts (D1a and D1b) and D2] and will be randomized in 2:1 ratio to receive TAK-994 or placebo for 28 days. The dose will be selected based on the safety and tolerability in Part A.

This multi-center trial will be conducted in the United States, Japan, China, Italy, France, and European Union. The overall duration of the study is 63 days. Participants will be followed up for 7 days after the last dose of study drug.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: First dose of study treatment to end of study follow-up (up to Day 35) in Part A

  2. Part A: Number of Participants Who Meet the Markedly Abnormal Value Criteria for Safety Laboratory Tests at Least Once Postdose During the Study

    Standard safety laboratory values (hematology, serum chemistry, urinalysis) were collected and compared to pre-specified criteria for markedly abnormal values. Markedly abnormal values criteria: Erythrocytes(10^12/L:<0.8xlower limit of normal(LLN), >1.2xupper limit of normal(ULN); Hemoglobin grams per litre(g/L):<0.8xLLN, >1.2xULN; Hematocrit voltage/volts(V/V):<0.8xLLN, >1.2xULN; Platelets(10^9/L):<75, >600; Leukocytes(10^9/L):<0.5xLLN, >1.5xULN; Alanine Aminotransferase units/litre(U/L):>3xULN, Aspartate Aminotransferase(U/L):>3xULN; Bilirubin micromoles/litre (umol/L):>1.5xULN; Alkaline Phosphatase(U/L):>3xULN; Gamma Glutamyl Transferase(U/L):>3 x ULN; Albumin(g/L):<25; Protein Total(g/L):<0.8xLLN, >1.2xULN;Glucose millimoles/litre(mmol/L):<2.8, >19.4; Calcium(mmol/L):<1.92, >2.77; Creatinine(umol/L):>1.5xULN; Urea(mmol/L):>10.7; Sodium(mmol/L):<130, >150; Potassium(mmol/L):<3.0, >5.3. Only categories with at least one participant with event are reported.

    Measured: First dose of study treatment to end of study follow-up (up to Day 35) in Part A

  3. Part A: Number of Participants Who Meet the Markedly Abnormal Value Criteria for Vital Sign Measurements at Least Once Postdose During the Study

    Vital signs (body temperature and sitting blood pressure) were collected and compared to pre-specified criteria for markedly abnormal values throughout the study. Markedly abnormal values criteria: Heart Rate (beats/min): <40, >115; Systolic Blood Pressure millimeters of mercury (mmHg): <90, ≥160, Change from Pre-Dose >20, Change from Pre-Dose >30, Time-matched Change from Baseline > 20, Time-matched Change from Baseline > 30; Diastolic Blood Pressure (mmHg): <50, ≥100, Change from Pre-Dose >20, Change from Pre-Dose >30, Time-matched Change from Baseline > 20, Time-matched Change from Baseline > 30; Respiratory Rate (breaths/min): >21; Temperature Celsius (C): >38.5. Only categories with at least one participant with event are reported.

    Measured: First dose of study treatment to end of study follow-up (up to Day 35) in Part A

  4. Part A: Number of Participants Who Meet the Markedly Abnormal Value Criteria for Safety Electrocardiogram (ECG) Parameters at Least Once Postdose During the Study

    A 12 lead ECG was performed, the ECG values were compared to pre-specified criteria for markedly abnormal values. Markedly abnormal values criteria: ECG Mean Heart Rate (beats/min): <40, >115; PR Interval milliseconds (msec): ≤80, ≥200; corrected QT interval by Fredericia (QTcF) Interval (msec): ≤300, >500, ≥30 change from baseline and >450; QRS Duration (msec): ≤80, ≥180. Only categories with at least one participant with event are reported.

    Measured: First dose of study treatment to end of study follow-up (up to Day 35) in Part A

  5. 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.

    Measured: Baseline and Week 8 (Day 56) in Parts B and C

Secondary outcomes (12)
  1. Part A: Cmax: Maximum Observed Plasma Concentration After Single Dose of TAK-994 at Day 1

    Measured: Pre-dose and at multiple time points (up to 14 hours) post-dose at Day 1 in Part A

  2. Part A: Tmax: Time of First Occurrence of Cmax After Single Dose of TAK-994 at Day 1

    Measured: Pre-dose and at multiple time points (Up to 14 hours) post-dose at Day 1 in Part A

  3. Part A: AUC(0-last): Area Under the Concentration-time Curve From Time 0 to Time of the Last Quantifiable Concentration After Single Dose of TAK-994 at Day 1

    Measured: Pre-dose and at multiple time points (up to 14 hours) post-dose at Day 28 in Part A

  6. Part A: AUC(0-t): Area Under the Concentration-time Curve From Time 0 to Time Tau Over a Dosing Interval of TAK-994 at Day 28

    Measured: Pre-dose and at multiple time points (Up to 12 hours) post-dose at Day 28 in Part A

  7. Parts B and C: Change From Baseline in the Epworth Sleepiness Scale (ESS) Total Score to Week 8

    The ESS is a subjective, self-administered, validated scale (scored 0 to 3) to respond to each of the 8 questions of daily life that asks participants how likely they are to fall asleep in those situations. The scores are summed to give an overall score of 0 to 24. Higher scores indicate stronger subjective daytime sleepiness, and scores below 10 are considered to be within the normal range. MMRM was used for analysis. Due to early termination of the study, no post-baseline secondary efficacy data for this outcome measure was collected and analyzed for participants in Part C: TAK-994 180 mg.

    Measured: Baseline and Week 8 (Day 56) in Parts B and C

  8. Parts B and C: Change From Baseline in Weekly Cataplexy Rate (WCR) at Week 8

    Participants will complete a daily patient-reported sleep diary to record self-reported narcolepsy symptoms. Participants will record episodes of cataplexy in the diary. The total number of events averaged for a week will be reported. WCR = (Total number of cataplexy over a number of non-missing diary days for a given duration/number of Non-missing diary days in that duration)*7. MMRM was used for the analysis. Due to early termination of the study, no secondary efficacy data was collected and analyzed for participants in Part C: TAK-994 180 mg.

    Measured: Baseline and Week 8 (Day 56) in Parts B and C

  9. Parts B and C: Number of Participants Who Experience at Least 1 TEAE During the Study

    An 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.

    Measured: First dose of study drug to end of study follow-up (up to Day 63) in Parts B and C

  10. Parts B and C: Number of Participants Who Met the Markedly Abnormal Value Criteria for Safety Laboratory Tests at Least Once Postdose During the Study

A Phase 2 study testing TAK-994 in people with Narcolepsy Type 1 (NT1) and Narcolepsy Type 2 (NT2), run by Takeda at 78 sites in 12 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 29 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 78 sites in United States, Japan, China, Italy, Spain and 7 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Oct 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part A: Number of Participants Who Experience at Least One Treatment Emergent Adverse Event (TEAE) During the Study (time frame: First dose of study treatment to end of study follow-up (up to Day 35) in Part A). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04096560, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Oct 2024.
