Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Major Depressive Disorder (MDD) is a distressing and highly prevalent condition which affects the individual's physical, emotional and cognitive well-being, making it one of the leading causes of disability worldwide.
Rationale:
Among the other symptoms, cognitive dysfunctions are one of the major impacts of this disorder and sometimes even overshadow the depressive symptoms2. Disturbances in cognitive functions affect a person's performance in life and work, affecting their concentration, focus, memory, planning, and decision making. Moreover, lack of sleep and dominant-negative thoughts associated with depression also make the cognitive ability worse.
Literature review has consistently demonstrated the negative impact on cognitive abilities affecting the productivity and functioning of individuals with MDD, despite the wide variety of study designs or locations. Cognitive dysfunctions is one of the most common effects reported throughout these studies.
Research gap identified:
Despite the repeated emphasis given in literature indicating the pivotal importance of cognitive abilities on the daily and professional working of humans, this is one domain that is very rarely studied separately in studies.
Relevance, importance, and applicability:
On September 30, 2013, the Food and Drug Administration approved vortioxetine for the treatment of adults with MDD. Vortioxetine's precise mechanism of action is unknown. It is hypothesized that vortioxetine works via blockade of serotonin reuptake; however, vortioxetine is pharmacologically different than other SSRIs because it also works by direct modulation of various serotonin receptors8,9. Chronic therapy with early approved antidepressants causes desensitization of 5-hydroxytryptamine (5-HT1A) on the presynaptic neuron, thereby creating a negative feedback loop and possibly reducing their antidepressive effects. Vortioxetine is an agonist of 5-HT1A on the presynaptic neuron, which can accelerate the antidepressant effects, similar to pindolol, and incorporate serotonin transporter (SERT) blockade10. This molecule acts as an antagonist, agonist, and partial agonist of multiple serotonin receptors and is designed to help reduce depressive symptoms for treatment and maintain response.
Vortioxetine has shown clinically significant results in Major Depressive Disorders (MDD), and possible positive effects on the cognitive abilities of the participants were noted in a few other studies with clinically significant improvement reported. An analysis by Baune et. al showed that Vortioxetine was the only anti-depressant that improved cognitive abilities. Many other studies have backed up this finding of Vortioxetine as an anti-depressant improving the cognitive functions of patients with MDD when taken as directed.
To the best of the knowledge of Principal Investigators, there was no local study done to assess the potential cognitive improvement seen with Vortioxetine when used as directed for the treatment of Major Depressive Disorders.
Purpose of this study:
As such the purpose of this trial is to provide evidence to assess this claim in the Pakistani population. This would be the first randomized trial dedicated for this assessment in the region with active control of one of the most commonly used Selective Serotonin and Norepinephrine Reuptake Inhibitors (SSNRIs) in Pakistan for the treatment of depression, Venlafaxine.
