Acorda Therapeutics, Inc. ACOR will present new data for INBRIJA during four oral platform presentations at the upcoming American Academy of Neurology Annual Meeting in Los Angeles, taking place April 21–27, 2018. INBRIJA is an investigational inhaled levodopa treatment for symptoms of OFF periods in people with Parkinson's disease taking a carbidopa/levodopa regimen.

"We are delighted to have the opportunity to present data from our Phase 3 clinical development program for INBRIJA, an investigational treatment for people with Parkinson's living with OFF periods, or the re-emergence of Parkinson's symptoms. To date, INBRIJA has been studied in more than 800 people with Parkinson's worldwide," said Burkhard Blank, M.D., Acorda's Chief Medical Officer. "OFF periods are one of the most disruptive aspects of Parkinson's and there is a tremendous unmet need for new treatment options to address them."

The INBRIJA data will be presented on Tuesday, April 24, 2018, during Session S26: Movement Disorders - Parkinson's Disease Clinical Trials from 3:30 PM – 5:30 PM PT. Details are as follows:

A New Drug Application for INBRIJA was accepted for review by U.S. Food and Drug Administration in February 2018, and FDA has set a target PDUFA date of October 5, 2018.

About Parkinson's and OFF periods

Parkinson's is a progressive neurodegenerative disorder resulting from the gradual loss of certain neurons responsible for producing dopamine. Approximately one million people in the U.S. and 1.2 million Europeans are diagnosed with Parkinson's; OFF periods are experienced by approximately 350,000 in the U.S. and 420,000 in Europe. It causes a range of symptoms including impaired movement, muscle stiffness and tremors. As Parkinson's progresses, people will experience OFF periods, which are characterized by the re-emergence of Parkinson's motor and non-motor symptoms. This re-emergence can occur even when an individual's treatment regimen has been optimized.

About INBRIJA^TM (levodopa inhalation powder) and ARCUS®

INBRIJA is a self-administered, orally inhaled levodopa (L-dopa) therapy in development for the treatment of symptoms of OFF periods in people with Parkinson's disease taking a carbidopa/levodopa regimen. INBRIJA utilizes Acorda's investigational ARCUS® platform for inhaled therapeutics. INBRIJA was designed to deliver a precise dose of a dry powder formulation of L-dopa through the lung. Oral medication can be associated with variable onset of action, as the medicine is absorbed through the gastrointestinal (digestive) tract before reaching the brain. Inhaled treatments enter the body through the lungs and reach the brain, bypassing the digestive system.

The proprietary name INBRIJA has been conditionally accepted by the U.S. Food and Drug Administration (FDA).
