MT Pharma America to Present Data on Investigational Edaravone and Amyotrophic Lateral Sclerosis at the 2017 American Academy of Neurology Annual Meeting

Analysis of Patient U.S. Health Claims Data of 170 Million Individuals
Identifies Potential Early Signals of ALS

JERSEY CITY, N.J., April 18, 2018 – Mitsubishi Tanabe Pharma America, Inc. (MTPA) today announced presentations on amyotrophic lateral sclerosis (ALS) at the 70 th Annual Meeting of the American Academy of Neurology (AAN) in Los Angeles, April 21-27.

“While it’s been nearly one year since the FDA approved a second treatment option for ALS, there is still much to learn about this devastating disease,” said Jean Hubble, M.D., Vice President of Medical Affairs, MTPA. “In particular, we are eager to share findings from an analysis that identified clinically relevant signs and symptoms differentiating ALS patients from the general population up to five years prior to diagnosis. This is critical given it often takes up to 12 to 14 months for ALS patients to be accurately diagnosed.”

ALS data to be presented at AAN include:

About RADICAVA^® (edaravone)
The U.S. Food and Drug Administration (FDA) approved RADICAVA^® (edaravone) on May 5, 2017 as a treatment for amyotrophic lateral sclerosis (ALS). 1 In clinical trials, 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.^1,2,3

RADICAVA is administered in 28-day cycles by intravenous infusion. It takes 60 minutes to receive each 60 mg dose. For the initial cycle, the treatment is infused daily for 14 consecutive days, followed by a two-week drug-free period. All cycles thereafter are infused daily for 10 days within a 14-day period, followed by a two-week drug-free period.

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.

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

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

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).
