NEW YORK, Feb. 5, 2013 /PRNewswire/ -- Attorney Advertising -- Bronstein, Gewirtz & Grossman, LLC announces that a class action suit was filed in the United States District Court for the Southern District of New York on behalf of purchasers of Kerx Biopharmaceuticals, Inc. ("Keryx" or the "Company") (NASDAQ CM: KERX) securities between June 1, 2009 and April 1, 2012 inclusive (the "Class Period"). On April 2, 2012, Keryx announced the top-line data from the perifosine X-PECT Phase 3 Clinical Trial. The Company revealed that the trial for refractory advanced colorectal cancer did not meet the primary endpoint of improving overall patient survival versus capecitabine and a placebo. On this news, Keryx share price fell from $4.98 or about 65% on March 30, 2012 to $1.74 on April 2, 2012. The complaint alleges violations of federal securities laws, including issuing a series of material or false misrepresentations to the market, which had the effect of artificially inflating the market price during the Class Period. The complaint alleges that defendants mislead investors about the timing and success of Keryx's clinical trial that tested whether the drug perifosine was effective in treating late stage colorectal cancer. No Class has yet been certified in the above action.
