=Acorda (ACOR) : FDA delays review of Parkinson's treatment

Shares of Acorda Therapeutics(ACOR) slid 19% Thursday, after the company said the U.S. Food and Drugs Administration has extended the review period for a treatment for symptoms of Parkinson Disease. The extension comes after Acorda submitted additional information on its Inbrija, an inhaled levodopa therapy that aims to reduce off times, or the periods when standard levodopa treatment stops working. The FDA determined that the additional information constituted a major amendment that would take longer to review. The regulator moved the review date back to Jan. 5, 2019 from Oct. 5, 2018. Parkinson's is a progressive neurodegenerative disorder that affects about 1 million people in the U.S. and 1.2 million people in Europe. Acorda shares have fallen 13.8% in 2018, while the S&P 500 SPX, +0.04% has gained 8.1%.
