Keryx Biopharmaceuticals, Inc. Announces Second Quarter 2003 Financial Results 
 
         - Keryx to Hold Investor Conference Call Tomorrow, Thursday, 
                      August 14, 2003 at 10:00 AM EDT - 
 
    NEW YORK, Aug. 13 / -- Keryx Biopharmaceuticals, Inc. 
(Nasdaq: KERX; London AIM: KRX), a biopharmaceutical company focused on the 
acquisition, development and commercialization of novel pharmaceutical 
products for the treatment of life-threatening diseases, including diabetes 
and cancer, released financial results for the second quarter ended  
June 30, 2003.   
    The net loss for the quarter ended June 30, 2003 of $(1,509,000), or 
$(0.07) per share, was $902,000 less than the net loss of $(2,411,000), or 
$(0.12) per share, for the year ago quarter.  The decrease in net loss was 
primarily attributable to the reduction of early stage research activities and 
associated personnel expenses resulting from restructuring programs initiated 
in 2002 and 2003.  This decrease was partially offset by a $186,000 non-cash 
impairment charge, arising from the Company's current restructuring program.  
The decrease was also partially offset by a $420,000 non-cash accelerated 
depreciation expense, taken in the second quarter of 2003, relating to the 
shortening of the useful life of the leasehold improvements in its Jerusalem 
facility and which was included in general and administrative expenses.  The 
decrease was further partially offset by increased non-cash compensation 
expense and lower interest income in the second quarter of 2003, as compared 
to the second quarter of 2002. 
    At June 30, 2003, the Company had cash, cash equivalents, interest 
receivable and investment securities of $21.0 million, compared to cash, cash 
equivalents, interest receivable and investment securities of $22.4 million at 
March 31, 2003 and $24.1 million at December 31, 2002. 
    Commenting on the quarter, Michael S. Weiss, Keryx's Chairman and Chief 
Executive Officer, said, "During this quarter, we continued to cut the 
operating burn rate of the Company while making significant strides towards 
the initiation of our U.S.-based clinical program for KRX-101, our advanced 
clinical-stage drug candidate for the treatment of diabetic nephropathy.  I am 
very excited that the esteemed Collaborative Study Group, the very same group 
that was responsible for conducting the trial which led to the approval of 
irbesartan for diabetic nephropathy, will be conducting our trial.  I view 
their participation as a major vote of confidence in KRX-101.  Additionally, I 
believe the recently launched S.O.A.R. program has the potential to result in 
several important collaborations with leading investigators from around the 
world who can help us further explore KRX-101's ability to potentially treat a 
number of diseases beyond diabetic nephropathy."  Mr. Weiss added, "We made 
substantial progress during the second quarter, and I look forward to building 
on this momentum in the second half of 2003."

10:00 am EDT.  In order to participate in the conference call, please call
