Valby, 2015-03-05 08:00 CET (GLOBE NEWSWIRE) -- For non US. Media only
H. Lundbeck A/S (Lundbeck) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion for a Type-II Variation related to the update of the European summary of the product characteristics (SmPC) for Brintellix.
The update of the SmPC provides physicians with new Brintellix data related to its effect on certain aspects of cognitive function and patient functioning in general, as measured by cognitive performance assessment (neuropsychological test such as Digit Symbol Substitution Test (DSST)) and by functional capacity assessment (University of San Diego Performance-Based Skills Assessment (UPSA)) in patients with major depression, commonly referred to as depression. Patients with depression have cognitive symptoms 94% of the time[i]. Cognitive symptoms encompass a wide variety of signs, including attention and concentration difficulties, problems with thinking speed and difficulty making decisions.[ii]
The CHMP positive opinion was reached after a review of comprehensive data from the international clinical program comprised of five studies assessing the safety and efficacy of Brintellix including its effect on cognitive performance and function. The application was based primarily on data from one recently completed clinical study (CONNECT) in addition to four clinical studies that were previously submitted as part of the original approval process, as well as a newly completed clinical pharmacology functional magnetic resonance imaging (fMRI) study[iii] in remitted patients with depression. The application, known as a Type II Variation, was submitted to the European Medicines Agency (EMA) in September 2014.
“We are delighted that Brintellix has received this positive opinion from the CHMP, particularly given the role cognitive deficits play in impacting treatment outcomes for many patients” said Anders Gersel Pedersen, Executive Vice President and Head of R&D at Lundbeck. “The encouraging data we have seen on Brintellix when addressing cognitive dysfunction reinforces our belief that Brintellix has the potential to help many patients with their treatment of depression”.
The variation will be implemented upon finalization of the linguistic review process by EMA, expected end of March.
Lundbeck announces publication of CONNECT study results
The peer-reviewed journal Neuropsychopharmacology has published the CONNECT trial results.[iv] The article “A Randomized, Placebo-Controlled, Active-Reference, Double-Blind, Flexible-Dose Study of the Efficacy of Vortioxetine on Cognitive Function in Major Depressive Disorder” is available online at http://www.ncbi.nlm.nih.gov/pubmed/25687662
In the publication, the authors conclude that “Brintellix is an efficacious and well-tolerated treatment for patients suffering from depression. In this study of adults with MDD and self-reported cognitive dysfunction, Brintellix was statistically significantly superior to placebo on the predefined primary analysis, an objective measure of cognitive functioning, and on both predefined key secondary endpoints of global clinical status and patient-reported cognitive functioning. Brintellix was also significantly superior to placebo in the treatment of depressive symptoms and in the improvement of functional capacity.”

About the CONNECT studyiv
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 functional capacity, 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 the two key secondary endpoints — patient-reported Perceived Deficits Questionnaire (PDQ) (p=0.001) and CGI-I (p<0.05). 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 cognitive functioning, as measured by the DSST performance showed that the improvement observed with Brintellix could be mainly attributed to 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, and it was statistically significantly different on the 2 key secondary endpoints PDQ, CGI-I as well as MADRS, the latter validating the study.
Common adverse events (≤ 5%) for Brintellix were nausea, headache, and diarrhea.
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[v]. A general assumption is that cognitive dysfunction is restored as mood symptoms of depression improve[vi]. However, studies have shown that daily life functioning, including work and family life often remain impaired even in remission[vii].
Research suggests that different factors may explain why improvement in depression-related symptoms is not followed by improvement in daily life functioning. These associated factors include residual symptoms, comorbidity, misdiagnosis and long-lasting cognitive impairment[viii].
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.
Brintellix is approved in the United- States, Europe, Canada, Chile, South Korea, Turkey, Australia, Hong Kong, Singapore and South Africa.
The World Health Organization has issued an Anatomical Therapeutic Chemical (ATC) code for Brintellix that places it in the category of "Other" antidepressants.
