Efficacy of Vortioxetine on Cognitive Functioning in Working Patients With Major Depressive Disorder
Bibliographic record
Abstract
OBJECTIVE: This post hoc analysis investigates the effect of vortioxetine on cognitive functioning and depressive symptoms in working adults with major depressive disorder (MDD). METHODS: Population data from FOCUS, a double-blind, randomized, placebo-controlled study investigating the efficacy of vortioxetine versus placebo on cognitive functioning and depression in patients with MDD, were used to analyze mean change from baseline scores for the Digit Symbol Substitution Test (DSST), Trail Making Test A/B (TMT-A/B), Stroop, and Perceived Deficits Questionnaire (PDQ). FOCUS, conducted from December 2011 through May 2013, included adult patients with recurrent MDD according to DSM-IV-TR criteria. Change in depression severity (Montgomery-Asberg Depression Rating Scale [MADRS] total score) was analyzed using data from 3 additional short-term placebo-controlled studies (2 of which included duloxetine) and 1 relapse prevention study. Analyses were done according to patients' working status at baseline and workplace position. All analyses were made versus placebo. RESULTS: In FOCUS, the effect versus placebo on the DSST was 5.6 for 10 mg and 5.0 for 20 mg (P < .001 for both doses) in working patients; the effect was 4.0 (P < .001 for both doses) in total study population. The effect remained significant when adjusting for change in MADRS. In patients with "professional" positions, the effect was 9.2 for 10 mg (P = .006) and 9.0 for 20 mg (P = .001). A similar pattern of results was also observed for TMT-A/B, Stroop, PDQ, and MADRS total score. The efficacy of duloxetine was not different in working patients (MADRS). CONCLUSIONS: The beneficial effects of vortioxetine on objective and subjective measures of cognitive functioning are greater in working patients with MDD; the observed benefits were independent of improvement in depressive symptoms. TRIAL REGISTRATION: This study is a secondary analysis of data from 5 registered trials: ClinicalTrials.gov identifiers: NCT01422213, NCT00635219, NCT00735709, NCT01140906, NCT00596817.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
