Item
      1.01. Entry into a Material Definitive Agreement.
On
      March
      23, 2006, Keryx Biopharmaceuticals, Inc. ("Keryx") issued a press release
      announcing that it has entered into an agreement to acquire Accumin
TM
,
      a
      novel, patent protected, diagnostic for the direct measurement and
      quantitation of total, intact urinary albumin, from AusAm Biotechnologies,
      Inc.
      ("AusAm"). Pursuant to the Asset Purchase Agreement (the "Agreement") dated
      February 6, 2006, between the parties, Keryx will acquire Accumin in exchange
      for up to 300,000 shares of Keryx common stock and a royalty arrangement under
      which Keryx may be required to pay up to a maximum of $16.1 million. Keryx
      believes that it will be required to issue approximately 200,000 shares of
      Keryx
      common stock at closing to AusAm. The Agreement was entered into in
      connection with a voluntary petition by AusAm for bankruptcy relief under
      Chapter 11 of the United States Bankruptcy Code. The bankruptcy court approved
      the Agreement on March 17, 2006. Pursuant to the Agreement, Keryx will register
      the shares issued to AusAm. A copy of the press release is filed as Exhibit
      99.1
      to this report and is incorporated herein by reference.
