Mitsubishi Tanabe Pharma America to Present on ALS Clinical Programs at 2019 Muscle Study Group Annual Scientific Meeting

Company to Share Details on Collaboration with ALS Patients & Caregivers to Inform Clinical Study Design

JERSEY CITY, N.J., September 20, 2019 – Mitsubishi Tanabe Pharma America, Inc. (MTPA) today announced three presentations on amyotrophic lateral sclerosis (ALS) at the 2019 Muscle Study Group Annual Scientific Meeting, including a podium presentation highlighting collaborative work with a group of ALS patients and caregivers to help inform the design of the REFINE-ALS biomarker study. The meeting will be held September 20 – 22 in Snowbird, Utah.

MTPA will present details about the approach taken to seek study input from the ALS Research Ambassadors, a group of patients and caregivers with specialized training from the ALS Clinical Research and Learning Institute.

“Our collaboration with the ALS Research Ambassadors was instrumental to ensuring the REFINEALS study is truly patient-centered,” said Stephen Apple, M.D., Senior Medical Director, Medical Affairs, MTPA. “The substantive feedback we received from ALS patients and their caregivers during the study design process allowed us to modify the study protocol to enhance patient convenience while maintaining scientific rigor.”

In addition, MTPA will present a poster on the use of a novel machine-learning risk-based analysis tool to determine if results from the phase 3 studies of edaravone may be generalizable to a broader patient population.

A second poster presentation will highlight an analysis of 10 clinical studies which indicated that certain ALS clinical trial inclusion criteria may influence study participants’ baseline characteristics.

Presentation details:

Friday, September 20 from 7:30 PM – 9:00 PM MDT

  • Evidence for Generalizability of Edaravone Efficacy Using a Novel Machine-Learning (ML) Risk-Based Analysis Tool (Poster presentation)
  • The Influence of Clinical Study Inclusion Criteria on Baseline Characteristics and Disease Progression in Amyotrophic Lateral Sclerosis (Poster presentation) Sunday, September 22 from 8:45 AM – 8:55 AM MDT
  • Engaging ALS Research Ambassadors to Help Design the REFINE-ALS Biomarker Study (Platform presentation)

REFINE-ALS is a trial designed to identify and measure specific biomarkers in up to 300 people with ALS who are starting treatment with RADICAVA® (edaravone). The study is sponsored by Mitsubishi Tanabe Pharma America, Inc. and led by Massachusetts General Hospital Neurological Clinical Research Institute. The REFINE-ALS study includes approximately 40 sites across the country and will utilize the expertise of multiple specialty laboratories to assess biomarker samples. The trial includes assessments of biomarkers for oxidative stress, inflammation, neuronal and muscle injury. Biomarkers will be measured prior to initiating treatment with RADICAVA, at the start of treatment, and at pre-specified time points throughout the 24-week study period (six cycles of treatment).

About RADICAVA® (edaravone)
The U.S. Food and Drug Administration approved RADICAVA® (edaravone) on May 5,2017, as a treatment for amyotrophic lateral sclerosis (ALS). 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.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 January 2019.

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. It is not known if RADICAVA will harm your unborn baby.

What are the possible side effects of RADICAVA?

  • RADICAVA may cause serious side effects including hypersensitivity (allergic) reactions and sulfite allergic reactions.
  • Hypersensitivity reactions have happened in people receiving RADICAVA and can happen after your infusion is finished.
  • RADICAVA contains sodium bisulfite, a sulfite that may cause a type of allergic reaction that can be serious and life-threatening. Sodium bisulfite can also cause less severe asthma episodes in certain people. Sulfite sensitivity can happen more often in people who have asthma than in people who do not have asthma.
  • Tell your healthcare provider right away or go to the nearest emergency room if you have any of the following symptoms: hives; swelling of the lips, tongue, or face; fainting; breathing problems; wheezing; trouble swallowing; dizziness; itching; or an asthma attack (in people with asthma).
