Keryx Biopharmaceuticals, Inc. Announces Third Quarter 2003 Financial Results 
 
              - Keryx to Hold Investor Conference Call Tomorrow, 
                 Tuesday, November 11, 2003 at 10:00 AM EST - 
 
    NEW YORK, Nov. 10  -- 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, today announced the financial results for the third quarter ended 
September 30, 2003. 
    The net loss for the quarter ended September 30, 2003 of $(1,556,000), or 
$(0.07) per share, was $1,476,000 less than the net loss of $(3,032,000), or 
$(0.15) per share, for the year ago quarter.  The decrease in net loss was 
primarily attributable to a $1,301,000 reduction in research and development 
expenses and a reduction of $174,000 in general and administrative expenses, 
resulting primarily from restructuring programs initiated in 2002 and 2003.  
The decrease was partially offset by lower interest income in the third 
quarter of 2003, as compared to the third quarter of 2002. 
    At September 30, 2003, the Company had cash, cash equivalents, interest 
receivable and investment securities of $19.7 million, compared to cash, cash 
equivalents, interest receivable and investment securities of $21.0 million at 
June 30, 2003 and $24.1 million at December 31, 2002. 
    Commenting on the quarter, Michael S. Weiss, Keryx's Chairman and Chief 
Executive Officer, said, "I am very pleased with the progress we have made to 
date, as we recently satisfied a major milestone which was the initiation of 
our Phase II/III U.S.-based clinical program for KRX-101, our advanced 
clinical-stage drug candidate for the treatment of diabetic nephropathy.  We 
are also honored to have the support of the Collaborative Study Group, and its 
tremendous success and experience in this disease area, in this clinical 
program.  We are excited about getting the program underway and strongly 
believe that the data from the Phase II portion of this Phase II/III clinical 
program will corroborate the robust results achieved in our 223-patient 
European Phase II study."  Mr. Weiss added, "During the quarter, in connection 
with our S.O.A.R. program for KRX-101, we also initiated important scientific 
collaborations with leading investigators who we hope will help us unlock 
additional potential clinical applications for KRX-101 beyond diabetic 
nephropathy and shed additional light on the drug's mechanistic 
characteristics.  We look forward to announcing additional S.O.A.R. 
collaborations in the near future."    
    Commenting on the financial results for the quarter, Mr. Weiss said, "In 
this quarter we proved once again that we are an extremely cost conscience 
organization that is able to achieve much on a modest budget.  Our core group 
of highly-focused, highly-skilled individuals remains focused on building 
value in KRX-101 and in-licensing or acquiring additional pipeline products."

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