A Study to Assess Change in Disease Activity and Adverse Events (AEs) With Cariprazine in the Treatment of Depressive Episodes in Pediatric Participants Participants (10 to 17 Years of Age) With Bipolar I Disorder.
(3112 Ped BPD)
What this study is about
Bipolar disorder is a severe chronic mood disorder that affects up to 4% of the adult population and 1.8% of the pediatric population in the United States. The treatment of the depressive episodes of bipolar disorder in the pediatric population has not been as widely studied as the treatment of depressive episodes in bipolar disorder in adults, therefore pharmacotherapeutic options are limited.

Primary outcome measures
Number of Participants with Adverse Events
Time frame: Baseline (Week 0) to Week 10
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a casual relationship with this treatment. The investigator assesses the relationship of each event to the use of the study. A serious adverse event (SAE) is an event that results in death, is life threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event, that based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment-emergent adverse events/ treatment emergent serious adverse events (TEAEs/TESAEs) are defined as any event that began or worsened in severity on or after the first dose of the study drug.
Abnormal Change from Baseline in Vital Signs
Time frame: Baseline (Week 0) to Week 10
Change in vital signs like systolic and diastolic blood pressure will be assessed.
Number of Participants with Incidence of Abnormal Clinical Laboratory Test Results
Time frame: Baseline (Week 0) to Week 6
Number of participants with incidence of abnormal clinical laboratory test results like hematology will be assessed.
Change in Electrocardiogram (ECG)
Time frame: Baseline (Week 0) to Week 6
12 -lead resting ECGs will be recorded. Parameters include RR interval, PR interval, QT interval, and QRS duration.
Change From Baseline in Simpson-Angus Scale (SAS)
Time frame: Baseline (Week 0) to Week 6
SAS is a 10-item rating scale for assessment of antipsychotic-induced parkinsonism in both clinical practice and research settings. Each item ranges from 0 (normal) to 4 (extreme symptoms). The scale consists of 1 item measuring gait (hypokinesia), 6 items measuring rigidity, and 3 items measuring glabella tap, tremor, and salivation, respectively.
Change from Baseline in Columbia-Suicide Severity Rating Scale (C-SSRS)
Time frame: Baseline (Week 0) to Week 10
The C-SSRS is a clinician-rated instrument that reports the severity of both suicidal ideation and behavior, with a higher score denoting more severe suicidal ideation and behavior.
Change From Baseline in Barnes Akathisia Rating Scale (BARS)
Time frame: Baseline (Week 0) to Week 6
BARS is a 4-item rating scale used to assess drug-induced akathisia. The scale comprises items for rating the observable restless movements that characterize the condition, the subjective awareness of restlessness, and any distress associated with the akathisia (each on a 4-point scale from normal \[0\] to severe \[3\]). In addition, there is a global severity for akathisia rated on a 6-point scale (absent \[0\] to severe akathisia \[5\]).
Change From Baseline in Abnormal Involuntary Movement Scale (AIMS)
Time frame: Baseline (Week 0) to Week 6
AIMS assesses abnormal involuntary movements, such as tardive dyskinesia, associated with antipsychotic drugs; it measures facial, oral, extremities, and trunk movements, as well as the participant's awareness of abnormal movements. The first 10 items are rated on a none (0) to severe (4) scale. There are an additional 2 items on dental status that are answered yes or no.
Change in Children's Depression Rating Scale - Revised (CDRS-R) Total Score
Time frame: Baseline (Week 0) to Week 6
The CDRS-R is a 17-item clinician-administered scale specifically developed for the assessment of depressive symptoms in children and adolescents. Total scores range from 17 to 113. In general, scores below 20 indicate an absence of depression, scores of 20 to 30 indicate borderline depression, and scores of 40 to 60 indicate moderate depression. The CDRS-R will be administered by a clinician with extensive professional training in mental illness.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
