  • Number of Participants With Treatment Emergent Adverse Events (AEs), Treatment Emergent Serious Adverse Events (SAEs), Treatment Related AEs and Treatment Related SAEs [ Time Frame: Baseline (Day 1) up to 13 Months ]
    An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment emergent are events between first dose of study drug and up to 28 days after last dose of study drug (up to 13 months) that were absent before treatment or that worsened relative to pretreatment state. AEs included both serious and non-serious AEs. Treatment-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. Relatedness to study drug was assessed by the investigator.

Current Secondary Outcome Measures  ICMJE
 (submitted: January 31, 2020)
  • Number of Participants With Suicidal Ideation as Per Columbia Suicide Severity Rating Scale (C-SSRS) Mapped to Columbia Classification Algorithm of Suicide Assessment (C-CASA) [ Time Frame: Baseline (Day 1), Post-baseline on Day 1 up to 12 Months ]
    Number of participants with C-CASA code 4 are reported. C-SSRS responses mapping to C-CASA suicidal ideation code 4 are as follows: "Yes" on "wish to be dead", "non-specific active suicidal thoughts", "active suicidal ideation with any methods (not plan) without intent to act", "active suicidal ideation with some intent to act, without specific plan", "active suicidal ideation with some intent to act, without specific plan".
  • Number of Participants With Suicidal Behavior as Per Columbia Suicide Severity Rating Scale (C-SSRS) Mapped to Columbia Classification Algorithm of Suicide Assessment (C-CASA) [ Time Frame: Baseline (Day 1), Post-baseline up to 12 Months ]
    Number of participants with C-CASA code 1 or 2 or 3 are reported. C-SSRS responses mapping to C-CASA suicidal behavior codes 1, 2, or 3 are as follows: (1) completed suicide; (2) suicide attempt (response of "Yes" on "actual attempt"); (3) preparatory acts toward imminent suicidal behavior ("Yes" on "aborted attempt", "interrupted attempt", "preparatory acts or behavior").
  • Number of Participants as Per Reliable Change Index (RCI) Category for Cogstate Detection Task [ Time Frame: Month 12 ]
    CogState brief battery consisted of 2 tasks- detection and pediatric identification task using a laptop computer with external response buttons. Prior tasks, participants were briefed rules, given an interactive demonstration and a sufficient number of practice trials. For each task, participant responded "yes" using a response button with dominant hand. Participants had to "respond as fast and as accurately as possible." Detection task: measured simple reaction time to assess psychomotor function. Participant pressed a "YES" response key as soon as they detected an event (ie, a card turning face up presented in the center of the computer screen). A participant's RCI was calculated by dividing the change from individual baseline score by ([square root 2] times WSD), where WSD is within-subject standard deviation from Cogstate detection task normative data. Improvement in cognition when RCI <=-1.65, decline in cognition when RCI =>1.65.
  • Number of Participants as Per Reliable Change Index Category for Cogstate Pediatric Identification Task [ Time Frame: Month 12 ]
    CogState brief battery consisted of 2 tasks-detection and pediatric identification task using a laptop computer with external response buttons. Prior tasks, participants were briefed rules, given an interactive demonstration and a sufficient number of practice trials. For each task, participant responded "yes" using a response button with dominant hand. Participants had to "respond as fast and as accurately as possible." Pediatric identification task: measured choice reaction time to assess visual attention. An event (a card turning face up) occurred in center of computer screen and participant decided if event met a predefined and unchanging criterion (is the color of the card black?); answered "YES" if criterion was met. A participant's RCI was calculated by dividing the change from individual baseline score by ([square root 2] times WSD),WSD=within-subject standard deviation from Cogstate task normative data. Improvement in cognition: RCI <=-1.65, decline in cognition: RCI =>1.65.
