(“Keryx” or the “Company”) (KERX) common stock during the period between March 2, 2016 and July 29, 2016, inclusive (the “Class Period”). This action was filed in the United States District Court for the Southern District of New York and is captioned Erickson v. Keryx Biopharmaceuticals, Inc., et al., No. 1:16-cv-06218 (S.D.N.Y.).

Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member.

The complaint charges Keryx and certain of its officers and directors with violations of the Securities Exchange Act of 1934. Keryx is a biopharmaceutical company that develops and markets treatments for renal disease. The Company’s lead product, Auryxia (ferric citrate), is an oral, ferric iron-based compound that is used for the control of serum phosphorus levels in patients with chronic kidney disease on dialysis. Keryx commenced its commercial launch of Auryxia in the United States in December 2014.

The complaint alleges that during the Class Period, defendants misrepresented and failed to disclose material adverse facts regarding the Company’s business and prospects, which were known to defendants or recklessly disregarded by them, including that: (a) the Company’s sole third-party contract manufacturer for Auryxia was experiencing manufacturing difficulties that would require it to cease manufacture of Auryxia while the problems were rectified; (b) without that contract manufacturer manufacturing Auryxia, Keryx would not have enough inventory of Auryxia to meet its projected sales guidance; (c) Keryx was attempting to get another third-party manufacturer for Auryxia approved by the FDA, but that approval would not come until at least November 2016; and (d) based on the foregoing, defendants lacked a reasonable basis for their positive statements about the Company, its business and financial prospects, and its ability to meet its 2016 guidance during the Class Period.

On August 1, 2016, Keryx issued a press release and conducted a conference call with investors and stock analysts. During the call, Keryx announced that due to previously undisclosed manufacturing and supply issues, the Company was facing an imminent supply interruption for Auryxia until at least October 2016 and it was withdrawing its fiscal 2016 guidance. Keryx also disclosed that it would not be able to get its second contract manufacturer approved by regulators until at least November 2016. On this news, the market price of Keryx common stock declined precipitously, falling $2.64 per share, or 36%, from its close of $7.36 per share on July 29, 2016 to close at $4.72 per share on August 1, 2016, on unusually high trading volume.

Plaintiff seeks to recover damages on behalf of all purchasers of Keryx common stock during the Class Period (the “Class”). The plaintiff is represented by Robbins Geller, which has extensive experience in prosecuting investor class actions including actions involving financial fraud.
