Primary outcomes

  1. Number of Participants With Treatment Emergent Adverse Events (AEs) by Severity

    Time frame: Baseline through follow-up (Day 112)

    An AE was any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. TEAEs were events between first dose of study drug and up to follow-up visit that were absent before treatment or that worsened after treatment. AEs presented below were TEAEs. The investigator was required to use clinical judgment to assess the potential relationship between investigational product and each AE, to define an treatment-related AE. Assessments of AE intensity were defined as mild (easily tolerated, causing minimal discomfort and not interfering with daily activities), moderate (causing sufficient discomfort and interferes with normal daily activities) and severe (preventing normal daily activities).

Secondary outcomes

  1. Number of Participants With Laboratory Abnormalities (Without Regard to Baseline Abnormality)

    Time frame: Baseline through Visit 10 (Day 91)

    Safety laboratory assessments included clinical chemistry, hematology, urinalysis, and other tests. Abnormality was determined at the investigator's discretion.

  2. Number of Participants With Vital Signs Meeting the Pre-defined Categorical Summarization Criteria

    Time frame: Baseline through Visit 10 (Day 91)

    Vital signs abnormality criteria: 1) supine systolic blood pressure (SBP) <90 millimeters of mercury (mmHg); 2) supine diastolic blood pressure (DBP) <50 mmHg; 3) supine pulse rate <40 or >120 beats per minute (bpm); 4) change from baseline (increase or decrease) in supine SBP >=30 mmHg; 5) change from baseline (increase or decrease) in supine DBP >=20 mmHg.

  3. Number of Participants With Electrocardiogram (ECG) Data Meeting the Pre-defined Categorical Summarization Criteria

    Time frame: Baseline through Visit 10 (Day 91)

    ECG assessments included pulse rate (PR), QT, heart rate, QTcF intervals and QRS complex. ECG abnormalities criteria included: PR interval value >= 300 msec, or baseline (BL) >200 msec and >=25% increase from BL, or BL <=200 msec and >=50% increase from BL; QRS interval value >= 140msec, or >=50% increase from BL; QTcF value >450 and <=480 msec, or >480 and <=500 msec, or >500 msec, or increase from BL>30 and <=60 msec, or >60msec.

  4. Number of Participants With Categorical Scores on the Columbia Suicide Severity Rating Scale (C-SSRS)

    Time frame: Week 0, 2, 4, 6, 8, 10, 12, 13-14

    The C-SSRS is an interview-based rating scale to systematically assess suicidal ideation and suicidal behavior. Participants who responded "yes" to the questions will be counted. Data relevant to the assessment of suicidality were mapped to the Columbia-Classification Algorithm of Suicide Assessment (C-CASA) codes.

  5. Number of Participants With Response to Patient Health Questionnaire-9 (PHQ-9)

    Time frame: Week 0, 2, 4, 6, 8, 10, 12, 13-14.

    The PHQ-9 is a 9 item self-report scale for the assessment of depressive symptoms. The PHQ-9 were completed by participants and reviewed by site staff at the pre-defined time points.
