A Subgroup Analysis of the Impact of Vortioxetine on Functional Capacity, as Measured by UPSA, in Patients with Major Depressive Disorder and Subjective Cognitive Dysfunction.
Background: We evaluated vortioxetine's effects on functional capacity in demographic and clinical subgroups of patients with major depressive disorder. Methods: This was an exploratory analysis of the CONNECT study (NCT01564862) that evaluated changes in functional capacity using University of California San Diego Performance-based Skills Assessment data, categorized by sex, age, education, employment status, and baseline disease severity (Montgomery-Åsberg Depression Rating Scale, Clinical Global Impressions-Severity of Illness). Results: Greater changes in University of California San Diego Performance-based Skills Assessment composite scores were observed with vortioxetine vs placebo in specific subgroups: males (∆+3.2), females (∆+2.9), 45-54 or ≥55 years (∆+5.6, ∆+3.4), working (∆+2.8), high school or greater education (∆+2.7, ∆+2.8), disease severity (Montgomery-Åsberg Depression Rating Scale, <30, ∆+3.5; ≥30, ∆+2.5; Clinical Global Impressions-Severity of Illness ≤4, ∆+2.8; >4, ∆+3.0), major depressive episodes (≤2, >2 [∆+2.7,+3.3]), and episode duration (≤22, >22 weeks [∆+3.7,+2.4]). Conclusions: Our findings support the need for additional studies to assess whether vortioxetine improves functional capacity within specific patient subgroups.
