NEW YORK, Feb. 22 /PRNewswire-FirstCall/ -- Keryx Biopharmaceuticals, Inc. (Nasdaq: KERX), a biopharmaceutical company focused on the acquisition, development and commercialization of medically important, novel pharmaceutical products for the treatment of life-threatening diseases, including diabetes and cancer (the 'Company'), today announced its results for the fourth quarter and year ended December 31, 2007 .

At December 31, 2007 , the Company had cash, cash equivalents, investment securities and interest receivable of $64.7 million , as compared to $125.6 million at December 31, 2006 .

The net loss for the fourth quarter ended December 31, 2007 was $29,261,000 , or $0.67 per share, compared to a net loss of $18,347,000 , or $0.42 per share, for the comparable quarter in 2006, representing an increase in net loss of $10,914,000 . The increase in net loss was primarily attributable to a $2,228,000 increase in research and development expenses related to the Company's Sulonex(TM) (sulodexide oral gelcap) pivotal Phase 3 and Phase 4 clinical program, a $4,372,000 increase in expenses related to KRX-0401, a $2,600,000 increase in expenses related to Zerenex, a $446,000 increase in expenses related to the Company's other clinical compounds and a $1,692,000 increase in non-cash compensation expense related to stock option and restricted stock grants.

The net loss for the year ended December 31, 2007 was $90,062,000 , or $2.07 per share, compared to a net loss of $73,764,000 , or $1.76 per share, for the year ended December 31, 2006 , representing an increase in net loss of $16,298,000 . The increase in net loss was primarily attributable to a $7,839,000 increase in research and development expenses related to the Company's Sulonex pivotal Phase 3 and Phase 4 clinical program, a $6,702,000 increase in expenses related to KRX-0401 (perifosine), a $3,294,000 increase in expenses related to Zerenex (ferric citrate) and a $1,580,000 increase in expenses related to the Company's other clinical compounds. The increase in net loss was also due to a $1,838,000 decrease in interest and other income. The increase in net loss was partially offset by a $4,252,000 decrease in non- cash compensation expense related to stock option and restricted stock grants.

Commenting on the year and the quarter, Michael S. Weiss, Keryx's Chairman and Chief Executive Officer, said, 'This was an important year for the Company as we made substantial progress toward the potential commercialization of Sulonex, including: completion of the active treatment portion of the SUN- MICRO Phase 3 trial with the subsequent completion of the trial in February 2008 ; enrollment of over 50% of the patients required for completion of the SUN-MACRO Phase 4 trial; completion of four Independent Data Safety Monitoring Committee (DSMC) meetings surrounding the Phase 3 and Phase 4 trials culminating in the fourth quarter DSMC final review of the safety and efficacy data related to the Sulonex Phase 3 trial, at which time the DSMC again found no cogent reason to recommend that we alter or terminate the study; and the completion of our first commercial-scale manufacturing facility with final validation anticipated in 2008.' Mr. Weiss, continued, 'With the Phase 3 trial now complete, we anxiously await the final results from the study, and continue to target making an announcement of the top line data before the end of next month. In preparation for the potential commercial launch of Sulonex, we continue to build our internal expertise, including key hires in commercial, medical affairs, quality operations, legal and accounting. Financially, we ended the year in line with our expectations and believe that we are well- positioned for an exciting and fruitful 2008.'
