简要总结
REFINE-ALS is a prospective, observational, longitudinal, multicenter study designed to identify biomarkers to serve as quantifiable biological non-clinical measures of Edaravone effects in ALS. Epigenetic and protein biomarkers will also be investigated.
详细描述
Treatment will be prescribed by HCPs in accordance with their clinical judgement and the prescribing information for Edaravone. The decision to prescribe Edaravone to the participants should be made separately from the decision to enroll then in the study. There will be no randomized assignments to treatment and no restrictions on the use of commercially available medications (but those participating in an experimental study, even if taking Edaravone, will be excluded). No experimental treatment is evaluated in this study. The intervention is limited to the collection of blood and urine samples for biomarker testing.
During the estimated study period, eligible patients who are prescribed Edaravone within the approved indication will be invited to participate in the study. An initial screening/baseline visit will be scheduled for participants who are considered for study participation.
Participants in this study will be followed from enrollment up to 24 weeks after treatment initiation (6 treatment cycles [each cycle consisting of 28 days], corresponding to a treatment period of approximately 24 weeks) or premature study discontinuation. Throughout the study period, the investigators will record participant baseline and follow-up information and perform clinical and biomarker assessments.
