Outcome Measures

Primary Outcomes (8)

• Part A: Number of Participants With Treatment-emergent Adverse Events (TEAEs)

  Day 10

• Part A: Number of Participants With Serious Adverse Events (SAEs)

  Day 10

• Part A: Number of Participants With Clinically Significant Abnormal Laboratory Parameters

  Day 10

• Part A: Number of Participants With Clinically Significant Abnormal Vital Signs Values

  Day 10

• Part A: Number of Participants With Clinically Significant Abnormal Electrocardiograms (ECGs) Findings

  Day 10

• Part A: Number of Participants With Clinically Significant Abnormal Electroencephalogram (EEG) Findings

  Day 8

• Part A: Number of Participants With Suicidal Ideation or Suicidal Behavior as Measured Using Columbia-suicide Severity Rating Scale (C-SSRS)

  The C-SSRS is an interview-based rating scale to systematically assess any suicidality, suicidal behavior, or suicidal ideation. Any suicidality is emergence of any suicidal ideation or suicidal behavior. Any suicidal behavior is indicated when response is "yes" for any these questions- actual attempt to suicide, engaged in non-suicidal self-injurious behavior, interrupted attempt, aborted attempt, preparatory acts. Any suicidal ideation is indicated when response is "yes" for any of these questions- wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with methods without intent to act or some intent to act, without specific plan or with specific plan and intent to suicide.

  Day 10

• Part B: Number of Participants With Suicidal Ideation or Suicidal Behavior as Measured Using C-SSRS

  The C-SSRS is an interview-based rating scale to systematically assess any suicidality, suicidal behavior, or suicidal ideation. Any suicidality is emergence of any suicidal ideation or suicidal behavior. Any suicidal behavior is indicated when response is "yes" for any these questions- actual attempt to suicide, engaged in non-suicidal self-injurious behavior, interrupted attempt, aborted attempt, preparatory acts. Any suicidal ideation is indicated when response is "yes" for any of these questions- wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with methods without intent to act or some intent to act, without specific plan or with specific plan and intent to suicide.

• Any clinically abnormal symptom or organ impairment found by medical history at screening, and physical examinations, vital signs, ECG finding, or laboratory test results that require medical treatment at screening or baseline
• Evidence of clinically significant disease (example, cardiac, respiratory, gastrointestinal, renal disease, sleep disorders) that in the opinion of the investigators could affect the participant's safety or interfere with the study assessments
