Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing

On March 25, 2009, Antigenics Inc. (the “Company”) received notification from The NASDAQ Stock Market that the NASDAQ Listing Qualifications Panel (the “Panel”) had determined to transfer the Company’s listing to The NASDAQ Capital Market and continue the Company’s listing on that market effective with the opening of trading on March 27, 2009. The Company’s shares will continue to trade under the ticker “AGEN.”

The Panel’s decision is subject to the condition that, among other things, the Company demonstrates compliance with all continued listing standards of The NASDAQ Capital Market on or before June 22, 2009. The Panel’s determination follows a hearing on January 29, 2009 at which the Panel considered the Company’s plan to regain compliance with the minimum $35 million market value of listed securities or the alternative $2.5 million stockholders’ equity requirement for continued listing. While the Company is taking steps to comply with the terms of the Panel decision, there can be no assurance that the Company will be able to do so.
