Primary Outcome Measures
NameTimeMethod
DBT Period: Change From Baseline to Week 116 in Global Outcome, as Measured by CDR-SBBaseline, Week 116

CDR was derived through semi-structured interview with the participant and an appropriate informant, and it rated impairment across six domains: memory, orientation, judgment, and problem solving, community affairs, home and hobbies, and personal care on a 5-point scale for which 0=no impairment, 0.5=questionable impairment, and 1, 2, and 3=mild, moderate, a...

OLE Period: Number of Participants With Adverse Events (AEs)From day of first dose in OLE period up to 14 weeks after the last OLE dose (up to 48 weeks)

An adverse event is any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product, regardless of causal attribution.

OLE Period: Number of Participants With Post-baseline Suicidal Ideation or Suicidal Behavior as Measured Using Columbia-Suicide Severity Rating Scale (C-SSRS)From day of first dose in OLE period up to 14 weeks after the last OLE dose (up to 48 weeks)

C-SSRS=assessment tool used to assess lifetime suicidality of a participant (at baseline) as well as any new instances of suicidality (C-SSRS since last visit).
