简要总结

This study will evaluate the efficacy and safety of SPN-812 (viloxazine extended release) in children 4 to 5 years of age with ADHD.

详细描述

This is a randomized, double-blind, placebo-controlled, multicenter, 2-arm (1:1), parallel-group, efficacy and safety/tolerability fixed-dose study of SPN-812 in preschool-age children (4 to 5 years old) with ADHD. Participants will be screened for eligibility for up to 4 weeks. Eligible participants will be treated with study medication for 6 weeks. The total duration of the study is up to 10 weeks.

  • Has a primary diagnosis of ADHD according to DSM-IV-TR criteria and confirmed with the Kiddie Schedule for Affective Disorders and Schizophrenia - Present and Lifetime Version (K-SADS-PL).
  • Has an ADHD-RS-IV-P Total Score of ≥ 28 (males) or ≥ 24 (females) at Visit 1 (Screening) and at Visit 2 (Baseline).
  • Has a CGI-S score of ≥ 4 (moderate or worse) at Visit 1 (Screening) and at Visit 2 (Baseline).
  • Has undergone an adequate course of non-pharmacologic treatment or is having symptoms severe enough to warrant pharmacologic treatment without prior non-pharmacologic treatment.
  • Is participating in a structured group activity (e.g., preschool, kindergarten, sports, Sunday school, summer camp or childcare program) at least 2 days a week during study so as to assess symptoms and impairment in a setting outside the home.
  • Has not initiated any behavioral intervention/therapy within 30 days of Visit 1 (Screening) and does not plan to initiate any new or discontinue any ongoing behavioral intervention/therapy during the study (e.g., subject is eligible if behavioral intervention/therapy is initiated 30 or more days prior to Visit 1 [Screening] and continues with a similar duration/frequency throughout their study).
  • Subjects who are on ADHD medication at Visit 1 (Screening), but whose ADHD symptoms are not well controlled on current ADHD medication (e.g., meets Inclusion Criterion #4), meet all other inclusion/

排除标准

  • , and discontinues ADHD medication at least 7 days prior to the day of Visit 2 (Baseline) are eligible to participate.
  • Has no current condition in the opinion of the Investigator that could confound efficacy assessments, safety assessments or increase participant risk.
  • Has lived with the same parent(s) or legal guardian(s) or has lived under a shared living arrangement (e.g., joint legal custody) for greater than or equal to 6 months prior to Visit 1 (Screening).
  • Has a body weight ≥5th percentile for age and sex at Visit 1 (Screening) and Visit 2 (Baseline).
  • Exclusion Criteria:
  • Has a diagnosis at Screening (per K-SADS-PL) of another psychiatric disorder that is considered to be the primary diagnosis rather than ADHD or has a comorbid psychiatric disorder secondary to ADHD that, in the opinion of the investigator (after consulting medical monitor), will likely interfere with study treatment adherence and/or impact study results.
  • Has a current diagnosis of a major neurological disorder. The eligibility of those who have seizures, a history of seizure-like events (e.g., syncope, myoclonus, severe muscle spasms), a family history of seizure disorder (immediate family, i.e., sibling, parent), and/or febrile seizures will be assessed on a case-by-case basis after consulting the medical monitor.
  • History of Bipolar Disorder diagnosed in a first degree relative.
  • Has global development delay or intellectual disability by medical history.
  • Has a current diagnosis of a significant (per Investigator's evaluation and/or judgement) systemic disease.
  • Has body mass index > 95th percentile for the subject's age and sex at Visit 1 (Screening) or Visit 2 (Baseline).
  • Has a mean resting systolic and diastolic blood pressure* that are both >95th percentile for age sex, and height and has a mean resting pulse rate* that is >95th percentile for age and sex (males: >117 bpm; females: >122 bpm) at Visit 1 (Screening) or Visit 2 (Baseline). * Note: The mean of three measurements while seated.
  • Has a clinically significant electrocardiogram finding(s) at Visit 1 (Screening).
  • Is currently taking SPN-812 for ADHD, has previously taken SPN-812 for ADHD, but discontinued due to a lack of efficacy or adverse reactions, or has history of allergic reaction, hypersensitivity or intolerance to viloxazine.
  • Has an allergy to or cannot swallow pudding and applesauce and cannot swallow intact capsule whole.
  • Has any food allergy, intolerance, restriction or special diet that, in the opinion of the Investigator, could contraindicate the subject's participation in the study.
  • Has received any investigational drug within the longer of 30 days or 5 half-lives prior to Visit 2 (e.g., first dose of study medication).
  • Has a positive urine drug test at Visit 1 (Screening). A positive test for amphetamines is allowed for subjects receiving a stimulant ADHD medication at Screening. The subject will be required to discontinue the stimulant for the duration of the study, beginning at least 7 days prior to Visit 2 (Baseline).
  • Is using of prohibited concomitant medications including known CYP1A2 substrates (e.g., theophylline, melatonin) during the Screening Period or (anticipated) for the duration of the study.
  • Any reason that, in the opinion of the Investigator, would prevent the subject from participating in the study.
  • Has suicidal ideation ("Yes" indicated on C-SSRS question 4 or 5) or suicidal behavior ("Yes" indicated on C-SSRS for any suicidal behavior) within 6 months prior to or the day of Visit 1 (Screening) or has attempted suicide ("Yes" indicated on C-SSRS for lifetime).

结局指标

主要结局

Change from Baseline in the Attention-Deficit/Hyperactivity Disorder Rating Scale, 4th Edition, Preschool Version (ADHD-RS-IV-P) Total Score at End of Study (Week 6)

时间窗: Baseline and Week 6

The Attention-Deficit/Hyperactivity Disorder Rating Scale, 4th Edition, Preschool Version (ADHD-RS-IV-P) consists of 18 items that correspond directly to the DSM-IV-TR criteria for ADHD. The scale is subdivided into two subscales: inattention ("IA", 9 items) and hyperactivity-impulsivity ("H/I", 9 items).The clinician rates the frequency and severity of each symptom on a 4-point Likert-type scale, where 0 = Never or rarely, 1 = Sometimes, 2 = Often, and 3 = Very often. The sum of the ratings of all 18 items yields the raw Total score (range: 0-54; the higher the Total score, the more severe the ADHD symptoms). Post-baseline raw Total scores are converted to a change from baseline Total score. A lower change from baseline ADHD-RS-IV-P Total Score (\<0) represents a better outcome.

次要结局

  • Change from Baseline in the Clinical Global Impression of Severity (CGI-S) Score at End of Study (Week 6)(Baseline and Week 6)
  • Clinical Global Impression of Change (CGI-C) Score at End of Study (Week 6)(Week 6)
  • Change from Baseline in Attention-Deficit/Hyperactivity Disorder Rating Scale, 4th Edition, Preschool Version (ADHD-RS-IV-P) Hyperactivity/Impulsivity Subscale Score at End of Study (Week 6)(Baseline and Week 6)
  • Change from Baseline in Attention-Deficit/Hyperactivity Disorder Rating Scale, 4th Edition, Preschool Version (ADHD-RS-IV-P) Inattention Subscale Score at End of Study (Week 6)(Baseline and Week 6)
  • Clinical Global Impression of Severity (CGI-S) Responder Rate (percentage of subjects with CGI-S score of 1 or 2) at End of Study (Week 6)(Baseline and Week 6)
  • Clinical Global Impression of Change (CGI-C) Responder Rate (percentage of subjects with CGI-C score of 1 or 2) at End of Study (Week 6)(Week 6)
  • Attention-Deficit/Hyperactivity Disorder Rating Scale, 4th Edition, Preschool Version (ADHD-RS-IV-P) Responder Rate (percentage of subjects with ≥ 50% Reduction in Change from Baseline) at End of Study (Week 6)(Baseline and Week 6)
