Mitsubishi Tanabe Pharma America to Present New ALS Research at MNDA's 35th International Symposium on ALS/MND

JERSEY CITY, N.J., Dec. 3, 2024 /PRNewswire/ -- Mitsubishi Tanabe Pharma America, Inc. (MTPA) today announced 10 presentations covering advances in amyotrophic lateral sclerosis (ALS) research at the Motor Neurone Disease Association (MNDA) 35^th International Symposium on ALS/MND, being held in Montreal, Canada, from December 6-8. 

"We are honored to participate in this year's MNDA symposium, where we will share insights from our preclinical, clinical and real-world studies on RADICAVA^® (edaravone) and RADICAVA ORS^® (edaravone) and discuss the evolving ALS treatment landscape," said Gustavo A. Suarez Zambrano, M.D., Vice President of Medical Affairs at MTPA. "Our commitment to advancing ALS research is underscored by over eight years of continuous contributions at this symposium. This dedication guides us in leveraging both clinical and real-world evidence to help support the ALS community."

RADICAVA ORS Results:
Final results from two multi-center, Phase 3b, double-blind, parallel group studies will be presented, including a comparison of daily dosing of RADICAVA ORS (edaravone) with the FDA-approved on/off regimen, assessed over 48 weeks (MT-1186-A02) and up to 96 weeks (MT-1186-A04). Additionally, safety data from a Phase 3 open-label safety extension study (MT-1196-A03) will be shared.

About RADICAVA^® (edaravone) and RADICAVA ORS^® (edaravone)
The U.S. Food and Drug Administration (FDA) approved RADICAVA^® (edaravone) on May 5, 2017, and the oral formulation RADICAVA ORS^® (edaravone) on May 12, 2022, for the treatment of amyotrophic lateral sclerosis (ALS). In 2024, the FDA recognized RADICAVA ORS with Orphan Drug Exclusivity based on the major contribution to patient care of the innovative oral formulation. RADICAVA is administered in 28-day cycles by intravenous (IV) 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. RADICAVA ORS is taken daily for 14 consecutive days followed by a 14-day drug-free period for the initial treatment cycle. For subsequent treatment cycles, RADICAVA ORS is taken for 10 days within a 14-day period followed by a 14-day drug-free period. RADICAVA ORS should be taken in the morning after overnight fasting. Patients should not eat or drink (except water) within one hour after taking RADICAVA ORS.¹

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. (MTPA). The MTPC group companies began researching ALS in 2001 through an iterative clinical platform over a 13-year period. In 2015, edaravone was approved as RADICUT^® for the treatment of ALS in Japan and South Korea. Marketing authorizations were subsequently granted in Canada (October 2018), Switzerland (January 2019), Indonesia (July 2020), Thailand (April 2021), Malaysia (December 2021) and Brazil (February 2024). Marketing authorization for RADICAVA^® Oral Suspension was granted in Canada (November 2022) and Switzerland (May 2023), and RADICUT^® Oral Suspension 2.1% was granted regulatory approval in Japan in December 2022. To date, in the U.S., RADICAVA and RADICAVA ORS have been used to treat over 16,000 people with ALS, with over 2.0-million days of therapy, and have been prescribed by over 2,400 HCPs.^2-4

IMPORTANT SAFETY INFORMATION

Hypersensitivity Reactions

RADICAVA (edaravone) and RADICAVA ORS (edaravone) are contraindicated in patients with a history of hypersensitivity to edaravone or any of the inactive ingredients of this product. Hypersensitivity reactions (redness, wheals, and erythema multiforme) and cases of anaphylaxis (urticaria, decreased blood pressure, and dyspnea) have occurred with RADICAVA.

Patients should be monitored carefully for hypersensitivity reactions. If hypersensitivity reactions occur, discontinue RADICAVA or RADICAVA ORS, treat per standard of care, and monitor until the condition resolves.

Sulfite Allergic Reactions

RADICAVA and RADICAVA ORS contain sodium bisulfite, a sulfite that may cause allergic-type reactions, including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown but occurs more frequently in asthmatic people.

Adverse Reactions

The most common adverse reactions (≥10%) reported in RADICAVA-treated patients were contusion (15%), gait disturbance (13%), and headache (10%). In an open label study, fatigue was also observed in 7.6% of patients receiving RADICAVA ORS.

Pregnancy

Based on animal data, RADICAVA and RADICAVA ORS may cause fetal harm.

To report suspected adverse reactions or product complaints, contact Mitsubishi Tanabe Pharma America, Inc., at 1-888-292-0058. You may also report suspected adverse reactions to the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
