Study Details

Study Description

Brief Summary

Immune checkpoint inhibitors (ICIs) are a group of novel immunotherapies that boost the body's own defense against the cancer by improving the immune system's ability to recognize and destroy cancer cells. While it is relatively well-documented that conventional cancer treatments (e.g., chemotherapy) are associated with cognitive impairment, virtually nothing is yet known about effects on cognition during and after ICI treatment. Due to significantly improved survival rates after ICI treatments, it becomes important to map possible adverse effects associated with these treatments. The investigators therefore investigate possible changes in cognitive function in a group of cancer patients from prior to ICI treatment to nine months later. A gender- and age- matched healthy control group will serve as a comparison. The study has the potential to broaden our understanding of associations between cognition, the brain, and the immune system and to provide clinically relevant knowledge about possible cognitive impairments associated with immunotherapy.

Detailed Description

This controlled prospective observational study will include two groups with a total of 84 participants. A total of 42 patients diagnosed with melanoma, referred to treatment with ICI will be enrolled in the study and examined prior to treatment with ICI (baseline), at eight weeks following baseline (T2), at 24 weeks following baseline (T3) and 12 weeks after treatment completed (T4). A total of 42 gender- and age- matched healthy controls will be included and assessed at similar time points. Assessments will include a battery of neuropsychological tests, questionnaires, blood samples, and Magnetic Resonance Imaging (MRI).

The main objectives of the study are to investigate:

Changes in cognitive functions over the course of treatment with ICIs.
Possible associations between changes in cognitive function and immune markers during and following ICI treatment.
Possible associations between changes in cognitive function and changes in brain morphology.
Changes over time in other possible adverse effects of ICI treatment, including psychological distress, sleep disturbances, and fatigue.

Outcome Measures

Primary Outcome Measures

Attention [Baseline, and week 8, 24 and 12 weeks after completed treatment]
Changes in attention as measured with WAIS-IV The Digit Span Forwards (scores with a minimum of 0 points to a maximum of 16 points - higher scores mean a better outcome)
Attention [Baseline, and week 8, 24 and 12 weeks after completed treatment]
Changes in attention as measured with Paced Auditory Serial Addition Test (scores ranging from a minimum of 0 and a maximum of 60 with higher scores indicating a better outcome)
Processing Speed [Baseline, and week 8, 24 and 12 weeks after completed treatment]
Changes in processing speed as measured with WAIS-IV The Digit Symbol coding (scores ranging from a minimum of 0 and a maximum of 135 with higher scores indicating a better outcome)
Processing Speed [Baseline, and week 8, 24 and 12 weeks after completed treatment]
Changes in processing speed as measured with Trail Making Test A (outcome is time in seconds)
Working memory [Baseline, and week 8, 24 and 12 weeks after completed treatment]
Changes in working memory as measured with WAIS-IV The Digit Span Backwards (scores with a minimum of 0 points to a maximum of 16 points - higher scores mean a better outcome)
Working memory [Baseline, and week 8, 24 and 12 weeks after completed treatment]
Changes in working memory as measured with WAIS-IV The Digit Span Ranking (scores with a minimum of 0 points to a maximum of 16 points - higher scores mean a better outcome)
Learning and memory [Baseline, and week 8, 24 and 12 weeks after completed treatment]
Changes in learning and memory as measured with the Hopkins Verbal Learning Test - Revised (part 1 include a minimum score of 0 and a maximum score of 36 with higher score indicating a better outcome, part 2 include a minimum score of 0 and a maximum score of 12 with higher scores indicating better outcomes)
Learning and memory [Baseline, and week 8, 24 and 12 weeks after completed treatment]
Changes in learning and memory as measured with Brief Visuospatial Memory Test - Revised (part 1 include a minimum score of 0 and a maximum score of 18 with a higher score indicating a better outcome, part 2 include a minimum score of 0 and a maximum score of 6 with higher scores indicating better outcomes)
Visuospatial ability [Baseline, and week 8, 24 and 12 weeks after completed treatment]
Changes in visuospatial ability as measured with WAIS-IV Matrix Reasoning (scores with a minimum of 0 and a maximum of 26 with higher scores indicating better outcomes)
Verbal fluency [Baseline, and week 8, 24 and 12 weeks after completed treatment]
Changes in verbal fluency as measured with the Controlled Oral Word Association Test, letter and animal (as many words as possible, more words indicating a better outcome. No maximum value)
Executive function [Baseline, and week 8, 24 and 12 weeks after completed treatment]
Changes in executive function as measured with the Trail Making Test B (outcome is time in seconds)

Secondary Outcome Measures

Cancer-related fatigue [Baseline, and week 8, 24 and 12 weeks after completed treatment]
Changes in fatigue severity as measured with The Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT fatigue) scale (range from 0 to 52. Items are reverse scored when appropriate to provide a scale in which higher scores represent better functioning or less fatigue)
