Radicava/Edaravone Findings in Biomarkers from ALS (REFINE ALS): Interim Analysis
Neuromuscular and Clinical Neurophysiology (EMG)
S35 - Amyotrophic Lateral Sclerosis (4:30 PM-4:42 PM)
006
To identify possible biomarkers that may serve as quantifiable, biological, nonclinical measures of the pharmacodynamic effect of edaravone in amyotrophic lateral sclerosis (ALS). Real-world treatment outcomes will be compared with biomarker changes.
Radicava® (edaravone), a US FDA-approved treatment for ALS, has been shown to slow the rate of physical functional decline.  Because treatment outcomes can vary, quantifiable biomarkers for edaravone may supplement and improve patient evaluation before (ie, identify likely responder) and during treatment (ie, measure treatment response).
This is a prospective, observational, longitudinal, multicenter (up to 40 sites) US study with ≥200 ALS patients who will receive edaravone for 24 weeks. All participants must either be treatment-naive or be more than 1 month without receiving any edaravone before enrollment.   Biomarker quantification and other assessments will be performed at baseline and during cycles 1, 3, and 6. Selected biomarkers of oxidative stress, inflammation, neuronal injury and death, and muscle injury, as well as biomarker discovery panels (EpiSwitchTM and SOMAscan®) will be evaluated and, when feasible, compared with biobanked samples. Clinical efficacy assessments will include the ALS Functional Rating Scale-Revised, King’s clinical staging, the Amyotrophic Lateral Sclerosis Assessment Questionnaire, the Appel ALS Rating Scale, slow vital capacity, hand-held dynamometry and grip strength, and the time to specified clinical milestones or death. DNA samples will be collected for potential genomic evaluation. The predicted rate of progression and survival, and their potential correlations with biomarkers, will be evaluated. Safety will be assessed, including adverse events related to the study, which will be reported throughout the study.
An update on the current status of the study will be provided at the meeting.
The findings will help to further the understanding of the pharmacodynamic effect of edaravone on selected biomarkers relevant to disease mechanisms and possible mode of drug activity.
