Initial Study Results Show a Single Oral Dose is Expected to Have Similar Pharmacokinetic Parameters as IV Infusion
JERSEY CITY, N.J., November 15, 2018 – Mitsubishi Tanabe Pharma America, Inc. (MTPA) today announced that Mitsubishi Tanabe Pharma group companies will present pharmacokinetic (PK) data on an investigational oral suspension formulation of edaravone for the treatment of amyotrophic lateral sclerosis (ALS) at the 29th International Symposium on ALS/MND being held December 7-9 in Glasgow, Scotland. The Phase 1 study showed oral edaravone is expected to have similar PK parameters to the current intravenous infusion.
The intravenous (IV) formulation of edaravone, known as RADICAVA® (edaravone), is a treatment option previously approved by the U.S. Food and Drug Administration (FDA) to slow the loss of physical function in ALS patients.
“The creation and development of an oral suspension of edaravone for the treatment of ALS could provide a beneficial new therapy option for this progressive disease,” said Joseph M. Palumbo, M.D., Vice President, Head of Medical Science and Translational Research, Mitsubishi Tanabe Pharma Development America. “We are committed to furthering the development of this new formulation as quickly as possible in an effort to advance care for people with ALS.”
The initial Phase 1 dose-ranging PK study confirmed that a single oral dose of edaravone has a similar PK profile when compared to IV infusion. No new safety findings were observed relative to IV infusion. Data collection is ongoing, and the latest results and its anticipated development plan will be presented at the upcoming Symposium.
Additional details regarding the oral formulation development program will be released when available.
About RADICAVA® (edaravone) IV
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 a clinical trial, people given RADICAVA demonstrated a 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
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. On October 3, 2018 edaravone was granted market authorization in Canada.

- 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).
