Outcome Measures

Primary Outcomes (2)

  • Change From Baseline in Hamilton Psychiatric Scale for Depression-17 Item (HAM-D17) Score

    HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression. Items are scored on either a 3-point (0 to 2) or a 5-point scale (0 to 4) with 0=none/absent and 4=most severe, for a maximum total score of 50. Higher scores indicate greater severity. FOT evaluation is defined as the last "on-therapy" evaluation, regardless of the number of days on therapy. Analysis on Observed cases (non-missing data) and Last observation carried forward (LOCF); LOCF method of imputation for any missing value at any visit.

    Baseline (Extension Study) up to Day 308 or Final On-Therapy (FOT) Evaluation

  • Percentage of Participants With Adverse Events (AEs) or Serious Adverse Events (SAEs)

    Any untoward medical occurrence in a participant who received study treatment was considered an AE without regard to possibility of causal relationship. An AE resulting in any of the following outcomes, or deemed to be significant for any other reason, was considered to be an SAE: death; initial or prolonged inpatient hospitalization; a life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; or congenital anomaly.

    Baseline (Extension Study) up to Day 329 or 15 days after last dose of study treatment

Secondary Outcomes (2)

  • Number of Participants With Categorical Scores on Clinical Global Impression-Improvement (CGI-I)

    Day 308 or FOT Evaluation

  • Change From Baseline in Clinical Global Impression-Severity of Illness [CGI-S] Score

    Baseline (Extension Study) up to Day 308 or FOT Evaluation

Eligibility Criteria

Age20 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Outpatients who have completed double-blind therapy in short-term study for the indication of major depressive disorder (MDD), including scheduled evaluations, with no major protocol violations and no study events that, in the opinion of the investigator, would preclude the subject's entry into the long-term, open-label study.

You may not qualify if:

  • Clinically important abnormalities on baseline (day 56 of the short-term study) physical examination, or any unresolved clinically significant abnormalities on electrocardiogram (ECG), laboratory test results, or vital signs recorded before day 56 in the previous short-term study for the indication of MDD.
