Mitsubishi Tanabe Pharma America, Inc. (MTPA) today announced a collaboration with the Massachusetts General Hospital (MGH) Neurological Clinical Research Institute (NCRI) to conduct a study designed to identify and measure specific biomarkers in people with amyotrophic lateral sclerosis (ALS). ?We are honored to be working with the team at MGH on our first clinical trial in the U.S.,? said Stephen Apple, M.D., Senior Medical Director, Medical Affairs, MTPA. ?This biomarker trial has sparked exponential interest in the ALS community, and with the help of MGH, we hope to further our understanding of the potential role these measures may have in evaluating a treatment response.? The ALS biomarker study, which will be sponsored by MTPA and led by MGH, has been designed to have 200 patients complete six cycles (24 weeks) of treatment, and will be conducted at up to 40 sites across the country. Findings may assist with identifying specific biomarkers as quantifiable, biological, non-clinical measures for the treatment effect of edaravone in people with ALS. The first biomarker study patient is anticipated to be enrolled late spring of 2019, with early interim analyses planned for later in the year. ?ALS is a complex disorder with diverse pathophysiology, and we do not currently have validated biomarkers for diagnosing or following ALS progression,? said study Primary Investigator James Berry, M.D., M.P.H., MGH NCRI, Boston. ?This study will broaden our understanding of numerous biomarkers that may be associated with ALS, including those for oxidative stress, inflammation, muscle and neuronal injury and death. It will increase our understanding of ALS and of the biological effects of edaravone in people with ALS undergoing therapy.? The biomarker study is a 24-week, prospective, observational, longitudinal, multicenter study. All participants will be newly prescribed commercial RADICAVA? (edaravone)and, once enrolled in this study, biomarker and clinical assessments will be obtained prior to initiating RADICAVA, as well as at start of treatment and at pre-specified time points throughout the study. Patient biomarker data and disease progression assessments will be compared to samples stored at biorepositories and progression models, respectively. 2 The study will evaluate the following biomarkers: ? Oxidative stress ? 4-hydroxynonenal (4-HNE), 8-Isoprostanes, 3-nitrotyrosine (3NT), 8-hydroxy-2'-deoxyguanosine (8OHdG), urate ? Inflammation ? matrix metalloproteinase-9 (MMP-9) ? Neuronal injury and death ? neurofilament (Nf) heavy and light chain proteins, urinary neurotrophin receptor p75 ? Muscle injury ? creatinine About Mitsubishi Tanabe Pharma America, Inc.

(edaravone) on May 5, 2017 as a treatment for amyotrophic lateral sclerosis (ALS).2 In a pivotal trial, people given RADICAVA experienced a 33 percent slower rate of decline in the loss of physical function, compared to placebo as measured by the ALS Functional Rating Scale-Revised (ALSFRS-R), a validated rating instrument for monitoring the progression of disability in people with ALS.1,3,4 Edaravone was discovered and developed for ALS by Mitsubishi Tanabe Pharma Corporation (MTPC) and commercialized in the U.S. by Mitsubishi Tanabe Pharma America, Inc. MTPC group companies began researching ALS in 2001 through an iterative clinical platform over a 13-year period. In 2015, edaravone was approved for use as a treatment for ALS in Japan and South Korea. Marketing authorization was granted in Canada in October 2018 and Switzerland in February 2019 3 IMPORTANT SAFETY INFORMATION Before you receive RADICAVA, tell your healthcare provider about all of your medical conditions, including if you: ? have asthma. ? are allergic to other medicines. ? are pregnant or plan to become pregnant.
