A Pilot Study Utilizing Escitalopram to Address Cognitive Dysfunction in Glioma Patients
Summary
Glioma is a cancer of glial cells, a class of tissue supporting neuronal function in the brain. As many as 85% of glioma patients experience cognitive impairment. This is not only from direct tumor involvement, but also from therapy such as cranial radiation and chemotherapy, which degrades neuronal function. There is evidence that serotonin selective reuptake inhibitors (SSRIs), such as escitalopram, improve cognition or prevent cognitive decline and may also improve outcomes critical to overall survival including functional independence, psychosocial stability, and quality of life. This pilot study will evaluate the effectiveness of the selective serotonin reuptake inhibitor (SSRI) escitalopram for treating cognitive impairment in newly diagnosed grade IV glioma over a 17 week treatment period.
Detailed description
As many as 85% of patients with glioma, a cancer of glial cells, experience cognitive impairment. This is not only from direct tumor involvement, but also from therapy such as cranial radiation and chemotherapy, which degrades neuronal function. Commonly, impairments in visuospatial skills and executive function are seen. There is evidence that serotonin selective reuptake inhibitors (SSRIs) such as escitalopram improve modulation and function of resting state networks, contribute to neuroplastic changes in brain regions subserving these abilities, and provide general functional support to neuronal cells. In addition to either improving cognition or preventing cognitive decline, treatment with an SSRI may also improve outcomes critical to overall survival in this vulnerable population, including functional independence, psychosocial stability, and quality of life. This study will characterize the degree of change in cognition/brain function in participants with grade IV glioma planning to undergo concurrent chemoradiation therapy followed by temozolomide and 17 weeks of treatment with an SSRI, escitalopram, and determine the degree of change in psychosocial function as assessed via ratings in mood and quality of life. The study hypothesis is that following treatment with escitalopram participants will experience improved cognitive and mood function over time.

Outcome measures
Primary
Change in Cognition
Changes in cognition will be measured using the NIH Toolbox neurocognitive assessments. The NIH Toolbox has excellent test / re-test reliability across composite domain scores r = .86 - .9263. It has also shown strong convergent (r = .78 - .9) and discriminant (r = .19 - .39) validities. It has been validated on groups of patients with Spinal Cord Injuries, Traumatic Brain Injury and Stroke. More recently a small group of patients diagnosed with diffuse glioma completed the NIH Toolkit Cognitive and Emotional batteries pre- and post-surgery. Results suggested good tolerance on the part of the patients and benefits of having a standardized battery that can be employed across sites. Paired t-test will be used to determine if the changes from baseline to the 17 week visit are significant. If assumptions for the paired t-test are not met, the non-parametric Wilcoxon sign rank test will be used instead.
Time frame: Baseline, 12-weeks and 17-weeks
Characterize the degree of change in cognition and brain function
Changes in cognition and brain function will be measured via Patient-Reported Outcome Measurement Information System (PROMIS) Neuro-QoL Item Bank v2.0 - Cognitive Function assessment completed at baseline, 12 weeks, and 17 weeks. A higher score on this measure indicate higher cognitive function. The change from baseline will be compared with the Wilcoxon sign rank test.
Time frame: Baseline, 12-weeks and 17-weeks
Change in Psycho-social Functions - PROMIS Neuro-QoL Item Bank v1.0 - Depression
The degree of change in psychosocial functions will be assessed via patient-reported ratings in mood and quality of life. The following assessments will be completed: PROMIS Neuro-QoL Item Bank v1.0 - Depression; PROMIS Neuro-QoL Item Bank v1.0 - Anxiety; PROMIS Neuro-QoL Item Bank v1.0 - Fatigue. Higher scores on these assessments indicate higher levels of the concept being assessed. The changes from baseline will be compared with the Wilcoxon sign rank test.
Time frame: Baseline, 12-weeks and 17-weeks
Change in Psycho-social Functions - PROMIS Neuro-QoL Item Bank v1.0 - Anxiety
The degree of change in psychosocial functions will be assessed via patient-reported ratings in mood and quality of life. The following assessments will be completed: PROMIS Neuro-QoL Item Bank v1.0 - Depression; PROMIS Neuro-QoL Item Bank v1.0 - Anxiety; PROMIS Neuro-QoL Item Bank v1.0 - Fatigue. Higher scores on these assessments indicate higher levels of the concept being assessed. The changes from baseline will be compared with the Wilcoxon sign rank test.
Time frame: Baseline, 12-weeks and 17-weeks
Change in Psycho-social Functions - PROMIS Neuro-QoL Item Bank v1.0 - Fatigue
The degree of change in psychosocial functions will be assessed via patient-reported ratings in mood and quality of life. The following assessments will be completed: PROMIS Neuro-QoL Item Bank v1.0 - Depression; PROMIS Neuro-QoL Item Bank v1.0 - Anxiety; PROMIS Neuro-QoL Item Bank v1.0 - Fatigue. Higher scores on these assessments indicate higher levels of the concept being assessed. The changes from baseline will be compared with the Wilcoxon sign rank test.
