- Late-breaking study results will be presented at the International College of Neuropsychopharmacology (CINP) World Congress in Vancouver, Canada, on 24 June 2014
- Brintellix 10-20 mg/day met the primary study endpoint in adult patients with major depression and showed a statistically significant improvement in cognitive performance as assessed by DSST versus placebo
- The study also met several secondary endpoints measuring symptoms of depression and patient outcomes; Brintellix was generally well tolerated.
- The study results are consistent with results from previous studies of Brintellix that demonstrated an improvement in cognitive performance in adult and in elderly patients with major depression
- Impairment in cognition (i.e., diminished ability to think or concentrate or indecisiveness) is a criterion item in the diagnosis of a major depression. Cognitive dysfunction affects functional impairment (i.e., workplace performance), and improvement in cognitive function significantly influences functional recovery from depression
Valby, Denmark, 16 June 2014 - H. Lundbeck A/S (Lundbeck) today announced results from the CONNECT study showing that Brintellix (vortioxetine) 10 mg/day to 20 mg/day in adults with major depressive disorder (MDD) met the primary study endpoint of demonstrating superiority versus placebo in cognitive function as measured by the Digit Symbol Substitution Test (DSST). These findings will be presented as a late-breaking poster at the 29 th International College of Neuropsychopharmacology (CINP) World Congress in Vancouver, Canada on 24 June 2014 [i] .
The objectives of this randomized, double-blind, placebo-controlled study were to evaluate the effects of Brintellix on cognitive function using objective neuropsychological tests associated with executive function, processing speed and attention after eight weeks of treatment in adults with major depression (MDD), while also confirming efficacy on overall symptoms of depression.
In the CONNECT study (NCT01564862), a total of 602 subjects were randomized (198 on Brintellix, 210 on duloxetine, and 194 on placebo). Adults (18-65 years) with MDD, MADRS≥26 and self-reported cognitive dysfunction were enrolled. The primary endpoint was change from baseline to Week 8 on the Digit Symbol Substitution Test (DSST). Key secondary endpoints, patient-reported Perceived Deficits Questionnaire (PDQ) and Clinical Global Impression – Global Improvement (CGI–I) Scale at Week 8 were analyzed in a pre-specified testing sequence using the full-analysis set (FAS). Additional endpoints included the objective performance-based University of San Diego Performance-Based Skills Assessment (UPSA) to measure functionality, the Montgomery–Åsberg Depression Rating Scale (MADRS) to assess efficacy in depression, and a pre-specified path-analysis to detect direct vs indirect effects of Brintellix on cognitive function.
Brintellix was statistically superior to placebo on the primary endpoint (the Digit Symbol Substitution Test or DSST) (p<0.05) and two key secondary endpoints – patient-reported Perceived Deficits Questionnaire (PDQ) and CGI-I. Brintellix was statistically superior to placebo on the MADRS (p<0.05) and UPSA (p<0.001) change from baseline at Week 8. A pre-specified path-analysis to detect direct vs. indirect effects of treatment on cognition supported that the beneficial impact of Brintellix on cognitive performance is mostly a direct effect and not only due to alleviation of overall depressive symptoms.
Duloxetine was included in the study as an active reference to demonstrate assay sensitivity for depression. Duloxetine was not statistically significantly different from placebo on the primary study endpoint (DSST) or UPSA, but was significant on the PDQ, MADRS and CGI-I secondary endpoints.
Common adverse events (>5%) for Brintellix were nausea, headache, and diarrhea.
Brintellix was approved by the U.S. Food and Drug Administration (FDA) for the treatment of Major Depressive Disorders in adults and by the European Commission for the treatment of adults with Major Depressive Episodes. More recently, the Australian Therapeutic Goods Administration (TGA) approved vortioxetine for the treatment Major Depressive Disorders in April 2014.
CONNECT study further builds upon established efficacy and tolerability profile of Brintellix
The findings add to previously reported clinical data showing that Brintellix improved cognitive performance in elderly patients with major depression [ii] and the placebo-controlled FOCUS study in adult patients with major depression [iii] . In addition, these data build upon pre-clinical in-vivo evidence suggesting that the observed improvement in cognitive function in depressed patients of Brintellix may be supported by the pharmacological profile of Brintellix, which has shown positive effects on cognition in animal models through enhanced neurotransmission and synaptic plasticity in brain areas critical for cognitive function. However, the precise contribution of the individual targets to the observed pharmacodynamic profile remains unclear and caution should be applied when extrapolating animal data directly to man.
About cognitive function in major depression
Cognitive dysfunction is well-documented in the different phases of major depression, and plays an important role in functional recovery from major depression [iv] . A general assumption is that cognitive dysfunction is restored as mood symptoms of depression improve [v] . This is also supported by studies that have shown that daily life functioning, including work and family life often remain impaired even in remission [vi] .
Research suggests that different factors may explain why improvement in depression-related symptoms is not followed by improvement in daily life functioning v . These associated factors include residual symptoms, comorbidity, misdiagnosis and long-lasting cognitive impairment [vii] .
Cognition is defined as the mental action or process of acquiring knowledge and understanding through thought, experience and the senses. It can be seen as comprised of several domains such as for example attention, memory, producing and understanding language, learning, reasoning, problem solving, and decision making. Cognition is generally impacted in major depression, and focus is often on four of the domains, executive function, attention, speed of processing and memory.
About Brintellix ® (vortioxetine)
Brintellix is an inhibitor of serotonin (5-HT) reuptake and is also an agonist at 5-HT1A receptors, a partial agonist at 5-HT1B receptors and an antagonist at 5-HT3, 5-HT1D and 5-HT7 receptors. Brintellix is considered to be the first and only compound with this combination of pharmacodynamic activity, although the mechanism of the antidepressant effect of Brintellix is not fully understood and has not been established.
Brintellix (vortioxetine) was discovered by Lundbeck researchers in Copenhagen, Denmark. The clinical trial program in the US was conducted jointly by Lundbeck and Takeda, and Takeda holds marketing authorization for the US market. Brintellix is a trademark of H. Lundbeck A/S and is used under license by Takeda Pharmaceuticals America, Inc.
The World Health Organization has issued an Anatomical Therapeutic Chemical (ATC) code for Brintellix that places it in the category of "Other" antidepressants.
