Keryx Biopharmaceuticals Announces Top-Line Data from the Perifosine (KRX-0401) X-PECT Phase 3 Clinical Trial

Keryx Biopharmaceuticals, Inc. reported today that the Phase 3 "X-PECT" (Xeloda® + Perifosine Evaluation in Colorectal cancer Treatment) clinical trial evaluating perifosine (KRX-0401) + capecitabine (Xeloda) in patients with refractory advanced colorectal cancer did not meet the primary endpoint of improving overall survival versus capecitabine + placebo.

This Phase 3 trial was conducted pursuant to a Special Protocol Assessment (SPA) agreement with the FDA.  468 patients at sixty-five U.S. sites participated in this study. 

Ron Bentsur, Chief Executive Officer of Keryx, stated, "We are all extremely disappointed with the results of the study.  We thank the investigators who participated in what we believe was a well-run study, despite the outcome.  We will evaluate whether our Phase 3 study of Perifosine in relapsed/refractory multiple myeloma will continue as planned."
Mr. Bentsur commented further, "With approximately $31 million in cash as of March 31, 2012, and a well-controlled burn rate, we plan to focus our resources on the pending completion of the Zerenex (ferric citrate) long-term Phase 3 study for end stage renal disease (ESRD) patients with hyperphosphatemia, expected in the fourth quarter of 2012, and the New Drug Application (NDA) filing for Zerenex which will hopefully follow shortly thereafter."

KRX-0401 (perifosine) is in-licensed by Keryx from AeternaZentaris Inc. in the United States, Canada and Mexico.
