Eligibility

Primary outcome measure(s)

• Number of Participants Experiencing Adverse Events — Up to approximately 50 days
  An 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 causal relationship with this treatment.
• Number of Participants with Clinical Significant Change From Baseline in Vital Sign Measurements — Up to approximately 20 days
  Number of participants with clinical significant change from baseline in vital sign measurements like systolic and diastolic blood pressure will be assessed.
• Number of Participants with Clinical Significant Change from Baseline in Electrocardiogram (ECG) — Up to approximately 20 days
  12-lead resting ECG will be recorded.
• Number of Participants with Clinical Significant Change in Physical Examinations — Up to approximately 20 days
  Number of participants with clinical significant change in physical examinations will be assessed.
• Number of Participants with Clinical Significant Change in Clinical Laboratory Test Results Like Hematology will be Assessed — Up to approximately 20 days
  Number of participants with clinical significant change in clinical laboratory test results will be assessed.
• Change from Baseline in Columbia-Suicide Severity Rating Scale (C-SSRS) — Up to approximately 20 days
  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 Abnormal Involuntary Movement Scale (AIMS) — Up to approximately 20 days
  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 From Baseline in Barnes Akathisia Rating Scale (BARS) — Up to approximately 20 days
  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 Simpson-Angus Scale (SAS) — Up to approximately 20 days
  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.
