A Study of TAK-994 in Adults With Type 1 and Type 2 Narcolepsy

Phase 2
Terminated
Conditions
Narcolepsy Type 1 (NT1)
Narcolepsy Type 2 (NT2)
Interventions
Drug: Placebo
Drug: TAK-994
Registration Number
NCT04096560
Lead Sponsor
Takeda
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.

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.

Inclusion Criteria
  1. 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.
  2. The participant's Epworth Sleepiness Scale (ESS) score must be greater than or equal to (>=) 10 at Day -1.
  3. Must be willing to discontinue all medications used for the treatment of NT1/NT2.
  4. 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 .
  5. 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.

Exclusion Criteria
  1. 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.
  2. Is an excessive (>600 mg/day) caffeine user 1 week before to the study screening.
  3. 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.

Primary Outcome Measures
NameTimeMethod
Part A: Number of Participants Who Experience at Least One Treatment Emergent Adverse Event (TEAE) During the StudyFirst dose of study treatment to end of study follow-up (up to Day 35) in Part A

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.

Part A: Number of Participants Who Meet the Markedly Abnormal Value Criteria for Safety Laboratory Tests at Least Once Postdose During the StudyFirst dose of study treatment to end of study follow-up (up to Day 35) in Part A

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.

Part A: Number of Participants Who Meet the Markedly Abnormal Value Criteria for Vital Sign Measurements at Least Once Postdose During the StudyFirst dose of study treatment to end of study follow-up (up to Day 35) in Part A

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.

Part A: Number of Participants Who Meet the Markedly Abnormal Value Criteria for Safety Electrocardiogram (ECG) Parameters at Least Once Postdose During the StudyFirst dose of study treatment to end of study follow-up (up to Day 35) in Part A

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.

Parts B and C: Change From Baseline in Average Sleep Latency as Assessed by the Maintenance of Wakefulness Test (MWT)Baseline and Week 8 (Day 56) in Parts B and C

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.

Parts B and C: Number of Participants Who Experience at Least 1 TEAE During the StudyFirst dose of study drug to end of study follow-up (up to Day 63) in Parts B and C

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.

Parts B and C: Change From Baseline in the Epworth Sleepiness Scale (ESS) Total Score to Week 8Baseline and Week 8 (Day 56) in Parts B and C

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.

Parts B and C: Change From Baseline in Weekly Cataplexy Rate (WCR) at Week 8Baseline and Week 8 (Day 56) in Parts B and C

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.
