A Phase 1, Single-dose, Sequential Cohort, Nonrandomized Crossover Trial to Assess the Pharmacokinetics, Safety, and Tolerability of Oral Brexpiprazole in Children (6 to< 13 Years Old) With Central Nervous System Disorders
A study to assess pharmacokinetics, safety and tolerability of brexpiprazole in children ages 6 to <13 years with CNS disorders.
A US based nonrandomized, sequential cohort, crossover trial to assess pharmacokinetics, safety and tolerability of brexpiprazole in children ages 6 to <13 years with CNS disorders who are receiving antipsychotic treatment for their medical condition.
Inclusion Criteria:
Male and female subjects between 6 and 12 years of age
Subjects with CNS disorders including, but not limited to, ADHD, autism spectrum disorders, bipolar I disorder (subjects 10 to 12 years old only for bipolar), conduct disorder, oppositional defiant disorder, or any psychotic disorder and who are receiving antipsychotic treatment for their medical condition. Subjects' diagnoses will be determined by the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) criteria and confirmed at screening using the Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime version (K-SADS-PL).
Subjects must be considered psychiatrically/medically appropriate for participation in a clinical trial in which they will receive two doses of an antipsychotic medication.
Subjects with good physical health, as determined by no clinically significant deviation from normal for all of the following, prior to enrollment in the trial:
Subjects who are within the 5th to 95th percentile for gender-specific BMI for age from the Centers for Disease Control and Prevention growth charts and weight at least 15 kg (approx. 33 lbs)
Ability to commit to remain fully abstinent or use 2 approved methods of birth control during the trial for 21 (± 2) days following the last dose of IMP for sexually active females of childbearing potential.
Ability, in the opinion of the PI, of the subject and the subject's legally acceptable representative or caregiver(s) to understand the nature of the trial and follow protocol requirements, including all of the following:
Exclusion Criteria:
Subjects with a clinical presentation or history that is consistent with delirium, dementia, amnesia, or other cognitive disorders; subjects with psychotic symptoms that are better accounted for by another general medical condition(s) other than those listed in the second inclusion criterion above, or direct effect of a substance (ie, medication, illicit drug use, etc.).
Subjects with a history of at least mild intellectual disability as determined by IQ < 70, clinical evidence, or a social or school history that is suggestive of intellectual disability.
Subjects who have any of the following:
Subjects with a lifetime history of a substance use disorder (as determined by the DSM-5 criteria), or current substance misuse including alcohol and benzodiazepines, but excluding caffeine and nicotine.
Subjects who currently have clinically significant neurological, hepatic, renal, metabolic, hematological, immunological, cardiovascular, pulmonary, or gastrointestinal disorders such as any history of myocardial infarction, congestive heart failure, HIV seropositive status/acquired immunodeficiency syndrome, or chronic hepatitis B or C. Medical conditions that are minor or well-controlled may be considered acceptable if the condition does not expose the subject to an undue risk of significant adverse event or interfere with assessments during the course of the trial.
Subjects with insulin dependent diabetes mellitus (IDDM) are excluded. Subjects with non-IDDM may be eligible for the trial if their condition is determined to be stable.
Subjects with epilepsy or a history of seizures (except for a single seizure episode, for instance childhood febrile seizure or post traumatic) or a history of severe head trauma or cerebrovascular disease (eg, stroke, transient ischemic attack, etc.).
Any major surgery within 30 days prior to the first dose of IMP.
Any history of significant bleeding or hemorrhagic tendencies.
Blood transfusions within 30 days prior to first dose of IMP.
Subjects with a positive drug screen for cocaine, marijuana (even if by prescription), or other illicit drugs, or alcohol are excluded and may not be retested or rescreened.
Subjects who have supine or standing diastolic blood pressure, after resting for at least 5 minutes, ≥ 95 mmHg.
Subjects who have had a dose of depot antipsychotics within 6 months of screening.
Consumption of alcohol or grapefruit, grapefruit juice, Seville oranges, or Seville orange juice within 72 hours prior to the first dose of IMP and throughout the trial
Subjects who participated in a clinical trial and were exposed to IMP within the last 30 days prior to screening or who participated in more than 2 interventional clinical trials within the past year.
Subjects with a history of neuroleptic malignant syndrome or hypersensitivity to atypical antipsychotics.
Subjects with a history of true allergic (i.e. not intolerance) response to more than one class of medications.
Subjects with a history of allergic reaction or a known or suspected sensitivity to any substance that is contained in the IMP formula.
Subjects who do not tolerate venipuncture or have poor venous access that would cause difficulty for collecting blood samples.
Prisoners or subjects who are compulsorily detained (e.g. juvenile detention, court-mandated treatment) for any reason.
Inability to tolerate oral medication or swallow tablets.
