Item 8.01Other Events

On August 29, 2017, Acorda Therapeutics, Inc. (the “Company”) issued a press release announcing that it received a Refusal to File (RTF) letter from the U.S. Food and Drug Administration (FDA) regarding its New Drug Application (NDA) for INBRIJA. INBRIJA is an investigational treatment for symptoms of OFF periods in people with Parkinson’s disease taking a carbidopa/levodopa regimen. Upon its preliminary review, FDA determined that the NDA, submitted on June 26, 2017, was not sufficiently complete to permit a substantive review. FDA specified two reasons for the RTF: first, the date when the manufacturing site would be ready for inspection, and, second, a question regarding the submission of the drug master production record. FDA also requested additional information at resubmission, which was not part of the basis for the RTF. The Company will seek immediate guidance, including a Type A meeting with the FDA, to respond to the issues, which it believes are addressable, and to seek clarification of what additional information will be required. The FDA has not requested or recommended additional clinical efficacy or safety studies. A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated by reference into this Item.
