MT Pharma America Begins Patient Insurance Benefits Investigation Process in Advance of Availability of RADICAVA^™ (Edaravone)

JERSEY CITY, N.J., July 25, 2017 – MT Pharma America, Inc. today announced that healthcare providers (HCPs) now can begin the insurance benefits investigation process for their patients in preparation for availability of RADICAVA^TM (edaravone), an intravenous infusion treatment approved in May by the U.S. Food and Drug Administration (FDA). RADICAVA is indicated for all adult patients diagnosed with amyotrophic lateral sclerosis (ALS),also known as Lou Gehrig’s disease, and is on schedule to be available to patients in the U.S. in mid-August 2017.

“We have initiated the benefits investigation process now to allow people diagnosed with ALS access to RADICAVA as soon as it becomes available,” said Atsushi Fujimoto, President, MT Pharma America. “We are committed to making the process of accessing RADICAVA as seamless as possible and encourage healthcare providers to begin the process now for their patients.”

The benefits investigation and product access process is initiated by the HCP and facilitated through the Searchlight Support^TM hub, which provides assistance for people who are prescribed RADICAVA. Key steps in the process include:

1. TREATMENT DECISION: Patient visits HCP, who determines whether RADICAVA is an appropriate treatment for him/her.
2. BENEFITS VERIFICATION: Before beginning treatment the patient’s insurance coverage must be confirmed:
   1. HCP submits Benefits Investigation and Enrollment Form to connect patient to Searchlight Support. Forms (available at www.RADICAVA.com/HCP)can be submitted by the HCP online through a secure HCP portal, faxed or mailed.
   2. Searchlight Support conducts rapid benefits investigation to confirm patient insurance coverage and assigns a patient ID.
   3. A Care Coordinator from Searchlight Support can help the HCP’s office identify a location for infusion service based on individual patient’s insurance benefits and geographical proximity (ALS center, home infusion, physician’s office, free-standing infusion center or hospital outpatient department).
   4. Case manager contacts patient to explain benefits and discuss co-pay support options.
3. SCHEDULING INFUSIONS: Patient or HCP office contacts infusion site or home infusion provider to schedule the first cycle of treatment.
4. RADICAVA ORDERED: Site of care submits order form with patient ID to Searchlight Support to obtain RADICAVA for scheduled treatment. Searchlight Support facilitates RADICAVA shipment from distributor to infusion site once available in mid-August.

RADICAVA^TM (Edaravone)
The U.S. Food and Drug Administration (FDA) approved RADICAVA^TM (edaravone) on May 5, 2017 as a new treatment option indicated for all adult patients diagnosed with amyotrophic lateral sclerosis (ALS).¹ In clinical trials, people given RADICAVA experienced a 33 percent lower rate of decline in 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 (e.g., Monday through Friday and the following Monday through Friday) within a 14-day period, followed by a two-week drug-free period.¹

Edaravone was discovered and developed for ALS by Mitsubishi Tanabe Pharma Corporation (MTPC) and will be commercialized in the U.S. by MT Pharma America. MTPC group companies began researching ALS in 2001 through a comprehensive clinical platform over a 13-year period. In 2015, edaravone was approved for use as a treatment for all patients diagnosed with ALS in Japan and South Korea.
