           KERYX BIOPHARMACEUTICALS, INC. ANNOUNCES FIRST QUARTER 2004
                               FINANCIAL RESULTS

     -REPORTS NON-CASH CHARGE RELATED TO ACCESS ONCOLOGY, INC. ACQUISITION-

 -KERYX TO HOLD INVESTOR CONFERENCE CALL ON MONDAY, MAY 10, 2004 AT 10:00AM EDT-

NEW YORK, NEW YORK, MAY 7, 2004 - Keryx Biopharmaceuticals, Inc. (NASDAQ: KERX;
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 released
financial results for the first quarter ended March 31, 2004.

As part of a previously announced acquisition of ACCESS Oncology, Inc., the
Company incurred a non-cash, acquired in-process research and development charge
in the quarter ended March 31, 2004 of $18.8 million, all of which was included
in research and development expenses. This charge arose as a result of purchase
accounting treatment for the acquisition, as mandated by accounting principles
generally accepted in the United States of America.

At March 31, 2004, the Company had cash, cash equivalents, interest receivable
and investment securities of $56.1 million, compared to cash, cash equivalents,
interest receivable and investment securities of $31.4 million at December 31,
2003, representing an increase of $24.7 million. This increase is primarily
attributable to the $31.8 million in net proceeds raised by the Company in a
private placement of common stock to institutional investors completed in
February 2004 and approximately $2.2 million of exercise proceeds from the
exercise of options and warrants during the first quarter ended March 31, 2004.
This increase was partially offset by approximately $7.4 million of assumed
liabilities, comprised of $6.3 million of debt and $1.1 million of accounts
payable and accrued liabilities, paid by the Company following the acquisition
of ACCESS Oncology, Inc.


The net loss for the quarter ended March 31, 2004 was $(21,823,000), or $(0.78)
per share, compared to a net loss of $(3,788,000), or $(0.19) per share, for the
quarter ended March 31, 2003. The increase in net loss in the first quarter of
2004, as compared to the first quarter of 2003, was primarily attributable to
the $18,800,000, or $(0.68) per share, non-cash acquired in-process research and
development charge taken in the first quarter of 2004 arising from the
acquisition of ACCESS Oncology, Inc.

Commenting on the quarter, Michael S. Weiss, Keryx's Chairman and Chief
Executive Officer, said, "This quarter was very successful for Keryx. Through
the acquisition of ACCESS Oncology, we built out our product pipeline with
KRX-0401 (Perifosine), our lead oncology compound in Phase II clinical
development. In addition, we raised $32 million from some of the most
prestigious institutional investors in the industry, and we view this as a major
vote of confidence in our compounds and our business plan. In the coming
quarters we intend to continue to build Keryx into a leading biotechnology
company through the clinical development of our lead product candidates KRX-101
and KRX-0401 and the pursuit of additional product acquisitions."
