For those statements, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. Among the factors that could cause our actual results to differ materially are the following: the risk that the MAA will not be accepted for review by the EMA due to deficiencies in the application or for other reasons; acceptance of the NDA filing represents only a preliminary evaluation of the application and is not indicative of deficiencies that may be identified during the FDA's review; a PDUFA goal date is subject to change and does not guarantee that the review of the NDA will be completed on a timely basis; the risk that the FDA, and/or EMA ultimately deny approval of the U.S. NDA, and/or MAA, respectively; the risk that SPAs are not a guarantee that the FDA will ultimately approve a drug candidate following filing acceptance; whether the FDA and EMA will concur with our interpretation of our Phase 3 study results, supportive data, or the conduct of the studies; whether Riona® will be successfully launched and marketed by our Japanese partner, Japan Tobacco, Inc. and Torii Pharmaceutical Co., Ltd.; whether, Zerenex, if approved by the FDA and/or EMA, will be successfully launched and marketed; if approved, whether any meaningful pharmacoeconomic benefits will be generated with the use of Zerenex; and other risk factors identified from time to time in our reports filed with the Securities and Exchange Commission.
