EXHIBIT INDEX The following designated exhibit is furnished herewith: Exhibit Description of Exhibit Number 99.1 AVANT Immunotherapeutics, Inc. Press Release, dated August 30, 2007

                                                                    Exhibit 99.1

            AVANT Receives Approval to Transfer Securities
                     to the NASDAQ Capital Market


    NEEDHAM, Mass.--(BUSINESS WIRE)--Aug. 30, 2007--AVANT
Immunotherapeutics, Inc. (Nasdaq: AVAN) announced today that on August
29, 2007 it received a letter from The NASDAQ Stock Market stating
that AVANT was approved to list its common stock on The NASDAQ Capital
Market. AVANT's common stock will be transferred to The NASDAQ Capital
Market from The NASDAQ Global Market at the opening of business on
August 31, 2007.

    Under The NASDAQ Capital Market, AVANT will continue to have until
January 2, 2008 to regain compliance with NASDAQ Marketplace Rule
4450(a)(5) (the "Minimum Bid Price Rule") in accordance with
Marketplace Rule 4450(e)(2). To regain compliance with the Minimum Bid
Price Rule, the closing bid price of AVANT's common stock must remain
at $1.00 per share or more for a minimum of ten consecutive business
days. AVANT will seek to regain compliance with the Minimum Bid Price
Rule by January 2, 2008 and is considering alternatives to address
compliance with the continued listing standards of The NASDAQ Stock
Market.

    AVANT currently meets all of the requirements for continued
listing on The NASDAQ Capital Market, except for the Minimum Bid Price
Rule as explained above, and believes the transfer to be in the best
interest of all stockholders. Additionally, the lower cost and listing
requirements of The NASDAQ Capital Market better meet AVANT's needs as
a small public company.
