NEW YORK, May 22, 2014 (GLOBE NEWSWIRE) -- Keryx Biopharmaceuticals, Inc. (Nasdaq: KERX) (the "Company") announced today that the U.S. Food and Drug Administration (FDA) has extended the initial Prescription Drug User Fee Act (PDUFA) goal date for its review of the Company's New Drug Application (NDA) seeking marketing approval of ZerenexTM (ferric citrate) by three months. The new PDUFA goal date is September 7, 2014.

The notification letter from the FDA states that the Company's recent submission, in response to a Chemistry, Manufacturing and Controls (CMC) section information request from the FDA, included substantial revisions to the CMC section of the NDA. The FDA considered the submission to be a major amendment to the NDA and is extending the goal date by three months to provide time for a full review of the submission.

"We believe that we have sufficiently responded to the questions that we have received to date and will work with the FDA to answer any additional questions that they may have in order to complete their review of the Zerenex NDA," commented Ron Bentsur, Chief Executive Officer of Keryx. "Our commercial team remains focused on preparing for the potential launch of Zerenex late in the third quarter."

Cautionary Statement

Some of the statements included in this press release, particularly those regarding the FDA's review, potential approval and subsequent commercialization of Zerenex, may be forward-looking statements that involve a number of risks and uncertainties. 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: while we continue to work to answer the FDA's questions prior to the revised PDUFA date, there is no assurance that we have or will answer such questions to the satisfaction of the FDA, that the FDA will not have additional questions, or that the FDA will ultimately approve the NDA during the current review cycle, if at all; 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 could ultimately deny approval of the U.S. NDA, and/or MAA, respectively; that the FDA and EMA may not 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; and other risk factors identified from time to time in our reports filed with the Securities and Exchange Commission.
