Item 3.01-Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing. On July 6, 2007, AVANT Immunotherapeutics, Inc. (the "Company") received a letter from the Listing Qualifications Department of The NASDAQ Stock Market indicating that the Company is not in compliance with NASDAQ Marketplace Rule 4450(a)(5) (the "Minimum Bid Price Rule") because the closing bid price per share for the Company's common stock has been below $1.00 per share for 30 consecutive business days. This notification has no effect on the listing of the Company's common stock at this time. The Company will have 180 calendar days, or until January 2, 2008, to regain compliance in accordance with Marketplace Rule 4450(e)(2). The Company will seek to regain compliance within the 180-day cure period and is considering alternatives to address compliance with the continued listing standards of The NASDAQ Stock Market. To regain compliance with the Minimum Bid Price Rule, the closing bid price of the Company's common stock must remain at $1.00 per share or more for a minimum of ten consecutive business days. If the Company does not regain compliance with The Minimum Bid Price Rule by January 2, 2008, NASDAQ will provide the Company with written notification that its common stock will be delisted. At that time the Company would be permitted to appeal NASDAQ's determination to delist the Company's common stock to a NASDAQ Listings Qualifications Panel. Alternatively, the Company can apply to list its common stock on the Nasdaq Capital Market and NASDAQ will determine whether the Company meets the Nasdaq Capital Market initial listing criteria as set forth in Marketplace rule 4310(c), except for the bid price requirement. If the Company meets the initial listing criteria, NASDAQ will notify the Company that it has been granted an additional 180 calendar days to come into compliance with the Minimum Bid Rule while on the Nasdaq Capital Market. On July 10, 2007 the Company issued a press release announcing its receipt of the notification letter. A copy of the press release is attached hereto as Exhibit 99.1. Item 9.01. Financial Statements and Exhibits. (d) Exhibits Exhibit Number Description of Exhibit 99.1 AVANT Immunotherapeutics, Inc. Press Release, dated July 10, 2007

EXHIBIT INDEX The following designated exhibit is furnished herewith: Exhibit Number Description of Exhibit 99.1 AVANT Immunotherapeutics, Inc. Press Release, dated July 10, 2007

                                                                    EXHIBIT 99.1

AVANT Receives NASDAQ Deficiency Notice Relating to Minimum Bid Price

    NEEDHAM, Mass.--(BUSINESS WIRE)--July 10, 2007--AVANT
Immunotherapeutics (Nasdaq: AVAN) announced today that on July 6, 2007
it received a letter from The NASDAQ Stock Market stating that for the
last 30 consecutive business days, the closing bid price per share for
AVANT's common stock has been below the $1.00 minimum per share
requirement for continued inclusion under NASDAQ Marketplace Rule
4450(a)(5).

    In accordance with NASDAQ Marketplace Rule 4450(e)(2), AVANT has
180 calendar days, or until January 2, 2008, to regain compliance by
maintaining a closing bid price per share of $1.00 or higher for a
minimum of 10 consecutive business days. The NASDAQ Letter has no
effect on the listing of AVANT's common stock at this time. AVANT will
seek to regain compliance within this cure period and is considering
alternatives to address compliance with the continued listing
standards of The NASDAQ Stock Market. If AVANT does not demonstrate
compliance within the required period AVANT will be issued a delisting
letter, which may be appealed at that time. If AVANT is unsuccessful
in meeting the minimum bid requirement during an initial 180-day
compliance period, AVANT may apply to transfer the listing of its
common stock to The Nasdaq Capital Market and receive an additional
180-day compliance period, if AVANT meets all initial listing
criteria, except for the minimum bid requirement, for that market as
set forth in Marketplace Rule 4310(c).
