Clinical Trial Summary

This prospective cohort study is designed to characterize the utility of sNfL as a biomarker in clinical practice. This study also aims to understand how access to sNfL measures affects patient and clinician knowledge of their disease status and capture how this may have the potential to influence clinical decision-making. Level of disability, cognitive changes, fatigue, depression, and quality of life to detect clinical and subclinical worsening will be measured. While there is strong evidence in support of sNfL as a potential biomarker, literature regarding the application of sNfL in a real-world clinical practice setting is lacking. Understanding the utility of this test to clinicians and patients as a biomarker of MS disease activity is essential. Additionally, the optimum sampling frequency in clinical practice should be investigated to further elucidate its practicality. Given recent advances in the treatment of MS, there is increasing need for convenient and accessible measures of treatment efficacy.

Intervention

Diagnostic Test:
• Serum Neurofilament Light
The purpose of this research is to investigate a biomarker, called serum neurofilament light (sNfL), which is measured in blood. This study will attempt to investigate whether or not sNfL is a useful tool for clinicians in patients diagnosed with relapsing remitting multiple sclerosis.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Evaluate the utility of sNfL levels to aid with clinical decision-making by examining clinicians' understanding of patient's clinical status before sNfL results are received vs. after sNfL results are received	This outcome is based on structured clinician questionnaires developed for this study. Prior to receiving patient sNfL results, clinicians will answer the question "My current clinical impression of this patient's disease status is (circle one): a. Stable, b. Suspected disease activity, c. Confirmed disease activity, d. At risk for relapse, e. Relapse, f. Other (please specify)." After receiving patient sNfL results, clinicians will answer the question "After reviewing this patient's sNfL results along with other diagnostic testing at this time, my opinion of the patient's disease status is (circle one): a. Stable, b. Suspected disease activity, c. Confirmed disease activity, d. At risk for relapse, e. Relapse, f. Other (please specify)" and these answers will be reported.	1 year
